Background The use of financial incentives and penalties to encourage uptake of healthy behaviors is increasingly seen as a viable intervention in developed countries . Previous review s of the effectiveness of financial incentives and penalties for encouraging the uptake of healthy behaviors have focused on individual behaviors making it difficult to draw overall conclusions about the effectiveness of such interventions . This systematic review will explore the effectiveness of financial incentives and penalties for encouraging a wide range of behaviors , including : smoking cessation , increased physical activity , healthier dietary intake , sensible patterns of alcohol consumption , safe sun , safe sex , and primary preventive clinical behaviors . Methods Systematic methods will be used to search existing literature and screen studies for inclusion . All studies that meet the following inclusion criteria will be included in the review : participants were 18 years old or older and living in high-income countries ; interventions included cash or cash-like incentives to promote the uptake of healthy behaviors , or cash or cash-like penalties to discourage unhealthy behaviors ; the comparator was usual care or no intervention ; study design was r and omized controlled trial , cluster r and omized controlled trial , controlled before and after study , or interrupted time series analysis . Two review ers will independently screen the publications to ensure they meet the inclusion criteria . Quality will be assessed by two research ers , working independently , using the Cochrane risk of bias tool . Meta- analysis will be conducted , if appropriate . Any studies identified as at ‘ high risk of bias ’ will be excluded from meta- analysis . Discussion This systematic review will provide policy-relevant recommendations for the use of financial incentives and penalties as a method of encouraging uptake of healthy behaviors Summary . — The empowerment of women , broadly defined , is an often-cited objective and benefit of social cash transfer programs in developing countries . Despite the promise and potential of cash transfers to empower women , the evidence supporting this outcome is mixed . In addition , there is little evidence from programs at scale in sub-Saharan Africa . We conducted a mixed- methods evaluation of the Government of Zambia ’s Child Grant Program , a poverty-targeted , unconditional transfer given to mothers or primary caregivers of young children aged zero to five . The quantitative component was a four-year longitudinal clustered-r and omized control trial in three rural districts , and the qualitative component was a one-time data collection involving in-depth interviews with women and their partners stratified on marital status and program participation . Our study found that women in beneficiary households were making more sole or joint decisions ( across five out of nine domains ) ; however , impacts translated into relatively modest increases in the number of decision domains a woman is involved in , on average by 0.34 ( or a 6 % increase over a baseline mean of 5.3 ) . Qualitatively , we found that changes in intrahousehold relationships were limited by entrenched gender norms , which indicate men as heads of household and primary decision makers . However , women ’s narratives showed the transfer increased financial empowerment as they were able to retain control over transfers for household investment and savings for emergencies . We highlight method ological challenges in using intrahousehold decision making as the primary indicator to measure empowerment . Results show potential for unconditional cash transfer programs to improve the financial and intrahousehold status of female beneficiaries , however it is likely additional design components are need for transformational change Recent evidence suggests that conditional cash transfer programs for schooling are effective in raising school enrollment and attendance . However , there is also reason to believe that such programs can affect other outcomes , such as the sexual behavior of their young beneficiaries .  Zomba Cash Transfer Program is a r and omized , ongoing conditional cash transfer intervention targeting young women in Malawi that provides incentives ( in the form of school fees and cash transfers ) to current schoolgirls and recent dropouts to stay in or return to school . An average offer of US$ 10/month conditional on satisfactory school attendance – plus direct payment of secondary school fees – led to significant declines in early marriage , teenage pregnancy , and self-reported sexual activity among program beneficiaries after just one year of program implementation . For program beneficiaries who were out of school at baseline , the probability of getting married and becoming pregnant declined by more than 40 percent and 30 percent , respectively . In addition , the incidence of the onset of sexual activity was 38 percent lower among all program beneficiaries than the control group . Overall , these results suggest that conditional cash transfer programs not only serve as useful tools for improving school attendance , but may also reduce sexual activity , teen pregnancy , and early marriage There is promising evidence that poverty-targeted cash transfer programs can have positive impacts on  adolescent transitions to adulthood in re source poor setting s , however existing research is typically from small scale programs in diverse geographic and cultural setting s. We provide estimates of the impact of a national unconditional cash transfer program , the Kenya Cash Transfer for Orphans and Vulnerable Children  , on pregnancy and early marriage among females aged 12 to 24 , four years after program initiation . The evaluation was design ed as a clustered r and omized controlled trial and ran from 2007 to 2011 , capitalizing on the existence of a control group , which was delayed entry to the program due to budget constraints . Findings indicate that , among 1549 females included in the study , while the program reduced the likelihood of pregnancy by five percentage points , there was no significant impact on likelihood of early marriage . Program impacts on pregnancy appear to work through increasing the enrollment of young women in school , financial stability of the household and delayed age at first sex . The Kenyan program is similar in design to most other major national cash transfer programs in Eastern and Southern Africa , suggesting a degree of generalizability of the results reported here . Although the objective of the program is primarily poverty alleviation , it appears to have an important impact on facilitating the successful transition of adolescent girls into adulthood Background Unconditional and conditional cash transfer programmes ( UCT and CCT ) show potential to improve the well-being of orphans and other children made vulnerable by HIV/AIDS ( OVC ) . We address the gap in current underst and ing about the extent to which household-based cash transfers differentially impact individual children ’s outcomes , according to risk or protective factors such as orphan status and household assets . Methods Data were obtained from a cluster-r and omised controlled trial in eastern Zimbabwe , with r and om assignment to three study arms – UCT , CCT or control . The sample included 5,331 children ages 6 - 17 from 1,697 households . Generalized linear mixed models were specified to predict OVC health vulnerability ( child chronic illness and disability ) and social protection ( birth registration and 90 % school attendance ) . Models included child-level risk factors ( age , orphan status ) ; household risk factors ( adults with chronic illnesses and disabilities , greater household size ) ; and household protective factors ( including asset-holding ) . Interactions were systematic ally tested . Results Orphan status was associated with decreased likelihood for birth registration , and paternal orphans and children for whom both parents ’ survival status was unknown were less likely to attend school . In the UCT arm , paternal orphans fared better in likelihood of birth registration compared with non-paternal orphans . Effects of study arms on outcomes were not moderated by any other risk or protective factors . High household asset-holding was associated with decreased likelihood of child ’s chronic illness and increased birth registration and school attendance , but household assets did not moderate the effects of cash transfers on risk or protective factors . Conclusion Orphaned children are at higher risk for poor social protection outcomes even when cared for in family-based setting s. UCT and CCT each produced direct effects on children ’s social protection which are not moderated by other child- and household-level risk factors , but orphans are less likely to attend school or obtain birth registration . The effects of UCT and CCT are not moderated by asset-holding , but greater household assets predict greater social protection outcomes . Intervention efforts need to focus on ameliorating the additional risk burden carried by orphaned children . These efforts might include caregiver education , and additional incentives based on efforts made specifically for orphaned children Summary Background Cash-transfer programmes can improve the wellbeing of vulnerable children , but few studies have rigorously assessed their effectiveness in sub-Saharan Africa . We investigated the effects of unconditional cash transfers ( UCTs ) and conditional cash transfers ( CCTs ) on birth registration , vaccination uptake , and school attendance in children in Zimbabwe . Methods We did a matched , cluster-r and omised controlled trial in ten sites in Manical and , Zimbabwe . We divided each study site into three clusters . After a baseline survey between July , and September , 2009 , clusters in each site were r and omly assigned to UCT , CCT , or control , by drawing of lots from a hat . Eligible households contained children younger than 18 years and satisfied at least one other criteria : head of household was younger than 18 years ; household cared for at least one orphan younger than 18 years , a disabled person , or an individual who was chronically ill ; or household was in poorest wealth quintile . Between January , 2010 , and January , 2011 , households in UCT clusters collected payments every 2 months . Households in CCT clusters could receive the same amount but were monitored for compliance with several conditions related to child wellbeing . Eligible households in all clusters , including control clusters , had access to parenting skills classes and received maize seed and fertiliser in December , 2009 , and August , 2010 . Households and individuals delivering the intervention were not masked , but data analysts were . The primary endpoints were proportion of children younger than 5 years with a birth certificate , proportion younger than 5 years with up-to- date vaccinations , and proportion aged 6–12 years attending school at least 80 % of the time . This trial is registered with Clinical Trials.gov , number NCT00966849 . Findings 1199 eligible households were allocated to the control group , 1525 to the UCT group , and 1319 to the CCT group . Compared with control clusters , the proportion of children aged 0–4 years with birth certificates had increased by 1·5 % ( 95 % CI −7·1 to 10·1 ) in the UCT group and by 16·4 % ( 7·8–25·0 ) in the CCT group by the end of the intervention period . The proportions of children aged 0–4 years with complete vaccination records was 3·1 % ( −3·8 to 9·9 ) greater in the UCT group and 1·8 % ( −5·0 to 8·7 ) greater in the CCT group than in the control group . The proportions of children aged 6–12 years who attended school at least 80 % of the time was 7·2 % ( 0·8–13·7 ) higher in the UCT group and 7·6 % ( 1·2–14·1 ) in the CCT group than in the control group . Interpretation Our results support strategies to integrate cash transfers into social welfare programming in sub-Saharan Africa , but further evidence is needed for the comparative effectiveness of UCT and CCT programmes in this region . Funding Wellcome Trust , the World Bank through the Partnership for Child Development , and the Programme of Support for the Zimbabwe National Action Plan for Orphans and Vulnerable Children Among policymakers , a common perception surrounding the effects of cash transfer programmes , particularly unconditional programmes targeted to families with children , is that they induce increased fertility . We evaluate the Zambian Child Grant Programme  , a government unconditional cash transfer targeted to families with a child under the age of 5 and examine impacts on fertility and household composition . The evaluation was a cluster r and omized control trial , with data collected over 4 years from 2010 to 2014 . Our results indicate that there are no programme impacts on overall fertility . Our results contribute to a small evidence base demonstrating that there are no unintended incentives related to fertility due to cash transfers Background There is increasing pressure to address the social determinants of health ( SDoH ) and health inequities through the implementation of culturally acceptable interventions particularly in Sub-Saharan Africa ( SSA ) where health outcomes are generally poor . Available evaluation research on cash transfers ( CTs ) suggests that the programs may influence the wider determinants of health in SSA ; yet , there has been no attempt to synthesize the evidence regarding their contribution to tackling the SDoH and health inequalities . To date , nearly all the review s on CTs ' impact on health have predominantly featured evidence from Latin America with limited transferability to the social , cultural , and political environments in SSA . Therefore , the aim of this study is to undertake a systematic review to assess the role of CTs in tackling the wider determinants of health and health inequalities in SSA . Methods / design A systematic review of published and unpublished literature on CTs ’ impact on health and health determinants covering the period 2000–2016 will be undertaken . Studies will be considered for inclusion if they present quantitative or qualitative data , including all relevant study design s. The SDoH conceptual framework will be used to guide the data extraction process . EPPI Review er software will be used for data management and analysis . Studies included in the review will be analyzed by narrative synthesis and /or meta- analysis as appropriate for the nature of the data retrieved . Discussion This review will provide empirical evidence on the impact of CTs on SDoH to inform CT policy , implementation , and research in SSA . The protocol follows the Preferred Reporting Items for Systematic Review and Meta- Analysis Protocol s ( PRISMA -P ) . Systematic review registration This protocol has been registered with the PROSPERO international prospect i ve register of systematic review s , reference CRD42015025015 Despite significant global efforts to improve vaccination coverage against major childhood diseases , vaccination rates are below 90 % . To eradicate diseases such as measles , however , vaccination rates close to 95 % are needed . We use a r and omized experiment to investigate the effect of a dem and incentive , a conditional cash transfer program , in improving  vaccination coverage in rural Nicaragua . Double-difference estimates show the program led to large increases in vaccination coverage , and these result ed in vaccination levels greater than 95 % for some vaccines . Effects were especially large for children who are typically harder to reach with traditional supply-side interventions PURPOSE This study investigates the causal effect of Kenya 's  unconditional cash transfer program on  mental health outcomes of young people . METHODS Selected locations in Kenya were r and omly assigned to receive unconditional cash transfers  in the first phase of Kenya 's Cash Transfer Program for orphans and Vulnerable Children . In intervention locations , low-income households and those with orphans and vulnerable childrens began receiving monthly cash transfers of $ 20 in 2007 . In 2011 , 4 years after program onset , data were collected on the psychosocial status for youth aged 15 - 24 years from households in intervention and control locations ( N = 1960 ) . The primary outcome variable was an indicator of depressive symptoms using the 10- question Center for Epidemiologic Studies Depression Scale . Secondary outcomes include an indicator for hopefulness and physical health measures . Logistic regression models that adjusted for individual and household characteristics were used to determine the effect of the cash transfer program . RESULTS The cash transfer reduced the odds of depressive symptoms by 24 percent among young persons living in households that received cash transfers . Further analysis by gender and age revealed that the effects were only significant for young men and were larger among men aged 20 - 24 years and orphans . CONCLUSIONS This study provides evidence that poverty-targeted unconditional cash transfer programs , can improve the mental health of young people in low-income countries The aim of this study is to assess whether the Government of Kenya 's Cash Transfer for Orphans and Vulnerable Children ( Kenya CT-OVC ) can reduce the risk of HIV among young people by postponing sexual debut . The program provides an unconditional transfer of US$ 20 per month directly to the main caregiver in the household . An evaluation of the program was implemented in 2007–2009 in seven districts . Fourteen Locations were r and omly assigned to receive the program and fourteen were assigned to a control arm . A sample of households was enrolled in the evaluation in 2007 . We revisited these households in 2011 and collected information on sexual activity among individuals between 15–25 years of age . We used logistic regression , adjusted for the respondent 's age , sex and relationship to caregiver , the age , sex and schooling of the caregiver and whether or not the household lived in Nairobi at baseline , to compare rates of sexual debut among young people living in program households with those living in control households who had not yet entered the program . Our results , adjusted for these covariates , show that the program reduced the odds of sexual debut by 31 percent . There were no statistically significant effects on secondary outcomes of behavioral risk such as condom use , number of partners and transactional sex . Since the CT-OVC provides cash to the caregiver and not to the child , and there are no explicit conditions associated with receipt , these impacts are indirect , and may have been achieved by keeping young people in school . Our results suggest that large-scale national social cash transfer programs with poverty alleviation objectives may have potential positive spillover benefits in terms of reducing HIV risk among young people in Eastern and Southern Africa OBJECTIVES The purpose of this study was to examine the effects on immunization coverage of 3 incentives for physicians -- a cash bonus for practice --wide increases , enhanced fee for service , and feedback . METHODS Incentives were applied at 4-month intervals over 1 year among 60 inner-city office-based pediatricians . At each interval , charts of 50 r and omly selected children between 3 and 35 months of age were review ed per physician . RESULTS The percentage of children who were up to date for diphtheria , tetanus , and pertussis and Haemophilus influenzae type b ; polio ; and measles-mumps-rubella immunization in the study 's bonus group improved by 25.3 percentage points ( P < .01 ) . No significant changes occurred in the other groups . However , percentage of immunizations received outside the participating practice also increased significantly in the bonus group ( P < .01 ) . Levels of missed opportunities to immunize were high in all groups and did not change over time . Physicians ' knowledge of contraindications was low . CONCLUSIONS Bonuses sharply and rapidly increased immunization cover-age in medical records . However , much of the increase was the result of better documentation . A bonus is a powerful incentive , but more structure or education may be necessary to achieve the desired results Background Diabetes is an increasing public health problem in the UK and globally . Diabetic retinopathy is a microvascular complication of diabetes , and is one of the leading causes of blindness in the UK working age population . The diabetic eye screening programme in Engl and aims to invite all people with diabetes aged 12 or over for retinal photography to screen for the presence of diabetic retinopathy . However , attendance rates are only 81 % , leaving many people at risk of preventable sight loss . Methods This is a three arm r and omized controlled trial to investigate the impact of different types of financial incentives ( based on principles from behavioral economics ) on increasing attendance at  diabetic eye screening appointments in London . Eligible participants will be aged 16 or over , and are those who have been invited to screening appointments annually , but who have not attended , or telephoned to rearrange an appointment , within the last 24 months . Eligible participants will be r and omized to one of three conditions:1.Control condition ( usual invitation letter)2.Fixed incentive condition ( usual invitation letter , including a voucher for £ 10 if they attend their appointment)3.Probabilistic incentive condition ( invitation letter , including a voucher for a 1 in 100 chance of winning £ 1000 if they attend their appointment ) . Participants will be sent invitation letters , and the primary outcome will be whether or not they attend their appointment . One thous and participants will be included in total , r and omized with a ratio of 1.4:1:1 . In order to test whether the incentive scheme has a differential impact on patients from different demographic or socio-economic groups , information will be recorded on age , gender , distance from screening center , socio-economic status and length of time since they were last screened . A cost-effectiveness analysis will also be performed . Discussion This study will be the first trial of financial incentives for improving uptake of diabetic eye screening . If effective , the intervention may suggest a cost-effective way to increase screening rates , thus reducing unnecessary blindness . Trial registration IS RCT N14896403 , 25 February Financial incentives are being used increasingly to encourage a wide array of health behaviors because of their well-established efficacy . However , little is known about how to translate incentive-based strategies to public health practice geared toward improving population -level health , and a dearth of research exists on how individuals respond to incentives through public health communication strategies such as direct mail . This study reports results of a population -based r and omized controlled trial testing a direct mail , incentive-based intervention for promoting mammography uptake . The study population was composed of a r and om sample of Minnesota women enrolled in Medicare fee-for-service and overdue for breast cancer screening . Participants ( N = 18,939 ) were r and omized into three groups : ( 1 ) Direct Mail only , ( 2 ) Direct Mail plus Incentive , and ( 3 ) Control . Both direct mail groups received two mailers with a message about the importance of mammography ; however , Mail plus Incentive mailers also offered a $ 25 incentive for getting a mammogram . Logistic regression analyses measured intervention effects . Results showed the odds for receiving mammography were significantly higher for the Direct Mail plus Incentive group compared with both Direct Mail only and Control groups . The use of incentives also proved to be cost-effective . Additionally , the Direct Mail only group was more likely to receive mammography than the Control group . Findings offer experimental evidence on how the population -based strategy of direct mail coupled with a financial incentive can encourage healthy behavior , as well as how incentive-based programs can be translated into health promotion practice aim ed at achieving population -level impact Goods-based contingency management interventions ( e.g. , those using vouchers or prizes as incentives ) have demonstrated efficacy in reducing cocaine use  , but cost has limited dissemination to community clinics . Recent research suggests that development of a cash-based contingency management approach may improve treatment outcomes while reducing operational costs of the intervention . However , the clinical safety of providing cash-based incentives to substance abusers has been a concern . The present 16-week study compared the effects of goods-based versus cash-based incentives worth $ 0 , $ 25 , $ 50 , and $ 100 on short-term cocaine abstinence in a small sample of cocaine-dependent methadone patients ( N = 12 ) . A within-subject design was used ; a 9-day washout period separated each of 8 incentive conditions . Higher magnitude ( $ 50 and $ 100 ) cash-based incentives ( checks ) produced greater cocaine abstinence compared with the control ( $ 0 ) condition , but a magnitude effect was not seen for goods-based incentives ( vouchers ) . A trend was observed for greater rates of abstinence in the cash-based versus goods-based incentives at the $ 50 and $ 100 magnitudes . Receipt of $ 100 checks did not increase subsequent rates of cocaine use above those seen in control conditions . The efficacy and safety data provided in this and other recent studies suggest that use of cash-based incentives deserves consideration for clinical applications of contingency management , but additional confirmation in research using larger sample s and more prolonged periods of incentive delivery is needed Opportunity  NYC-Family Rewards was the first conditional cash transfer , r and omized controlled trial for low-income families in the United States . From 2007 to 2010 , Family Rewards offered 2,377 New York City families cash transfers  that were conditional upon their investments in education , preventive health care , and parental employment . Their health and other outcomes were compared to those of a  control group of 2,372 families . The experiment led to a modest improvement in health insurance coverage and a large increase in the use of preventive dental care . It improved parents ' perception of their own health and levels of hope , mainly through improvements in reported financial well-being . While the program 's impacts on physical health were weaker , our study might not have captured effects on chronic disease risk that take longer to accrue . In the context of New York City 's operating social-safety-net programs , conditional cash transfers may have led to positive , albeit modest , improvements in the health of poor families OBJECTIVE This study determined the effect of 2 financial incentives --- bonus and enhanced fee-for-service --- on documented immunization rates during a second period of observation . METHODS Incentives were given to 57 r and omly selected inner-city physicians 4 times at 4-month intervals based on the performance of 50 r and omly selected children . Coverage from linked records from all sources was determined for a sub sample of children within physician offices . RESULTS Up-to- date coverage rates documented in the charts increased significantly for children in the bonus group ( 49.7 % to 55.6 % ; P < .05 ) and the enhanced fee-for-service group ( 50.8 % to 58.2 % ; P < .01 ) compared with the control group . The number of immunizations given by these physicians did not change significantly , although the number of immunizations given by others and documented by physicians in the bonus group did increase ( P < .05 ) . Up-to- date coverage for all groups increased from 20 to 40 percentage points when immunizations from physician charts were combined with other sources . CONCLUSIONS Both financial incentives produced a significant increase in coverage levels . Increases were primarily due to better documentation not to better immunizing practice s. The financial incentives appeared to provide motivation to physicians but were not sufficient to overcome entrenched behavior patterns . However , true immunization coverage was substantially higher than that documented in the charts Background Smoking during pregnancy is harmful to the unborn child . Few smoking cessation interventions have been successfully incorporated into st and ard antenatal care . The main aim of this study is to determine the feasibility of a personal financial incentive scheme for encouraging smoking cessation among pregnant women . Design A pilot r and omised control trial will be conducted to assess the feasibility and potential effectiveness of two varying financial incentives that increase incrementally in magnitude ( $ 20 vs. $ 40AUD ) , compared to no incentive in reducing smoking in pregnant women attending an Australian public hospital antenatal clinic . Method Ninety ( 90 ) pregnant women who self-report smoking in the last 7 days and whose smoking status is biochemically verified , will be block r and omised into one of three groups : a. No incentive control group ( n=30 ) , b. $ 20 incremental incentive group ( n=30 ) , and c. $ 40 incremental incentive group ( n=30 ) . Smoking status will be assessed via a self-report computer based survey in nine study sessions with saliva cotinine analysis used as biochemical validation . Women in the two incentive groups will be eligible to receive a cash reward at each of eight measurement points during pregnancy if 7-day smoking cessation is achieved . Cash rewards will increase incrementally for each period of smoking abstinence . Discussion Identifying strategies that are effective in reducing the number of women smoking during pregnancy and are easily adopted into st and ard antenatal practice is of utmost importance . A personal financial incentive scheme is a potential antenatal smoking cessation strategy that warrants further investigation . Trial registration Australian New Zeal and Clinical Trials Registry ( ANZCTR ) number : The cash component of Oportunidades , a large conditional cash transfer ( CCT ) program in Mexico , has previously been shown to be associated with better outcomes for child growth and development . The objective of this analysis was to determine whether the cash transfers were also associated with positive outcomes for adult health .  Oportunidades  was originally r and omized across 506 rural ( < 2500 inhabitants ) communities assigned to immediate incorporation into the program in 1997 or incorporation 18 mo later . Adults ( n = 1649 early , n = 2039 late intervention ) aged 18 - 65 y were then assessed in 2003 . All of the households included in the analysis reported here complied with Oportunidades 's requirements for the entire period , but some received higher cumulative cash transfers because they were living in communities r and omized to begin receiving transfers earlier and /or they accumulated cash at a faster rate because they had more school-aged children at baseline . Our primary findings were that a doubling of cumulative cash transfers to the household was associated with higher BMI ( beta = + 0.83 , 95 % CI 0.46 , 1.20 ; P < 0.0001 ) , higher diastolic blood pressure ( beta = + 1.19 , 95 % CI 0.09 , 2.29 ; P = 0.03 ) , and higher prevalence of overweight [ odds ratio ( OR ) = 1.41 , 95 % CI 1.18 , 1.67 ; P < 0.0001 ) , grade I obesity ( OR = 1.41 , 95 % CI 1.14 , 1.75 ; P = 0.002 ) , and grade II obesity ( OR = 1.57 , 95 % CI 1.05 , 2.36 ; P = 0.03 ) , while controlling for a wide range of covariates , including household composition at baseline . Oportunidades has been portrayed as a model for CCT programs worldwide , but the results reported here support the notion that the cash component of Oportunidades may be negatively associated with some adult health outcomes BACKGROUND Scaling-up of effective preventive interventions in child and maternal health is constrained in many developing countries by lack of dem and . In Latin America , some governments have been trying to increase dem and for health interventions by making direct payments to poor households contingent on them keeping up-to- date with preventive health services . We undertook a public health programme effectiveness trial in Honduras to assess this approach , contrasting it with a direct transfer of re sources to local health teams . METHODS 70 municipalities were selected because they had the country 's highest prevalence of malnutrition . They were allocated at r and om to four groups : money to households ; re sources to local health teams combined with a community-based nutrition intervention ; both packages ; and neither . Evaluation surveys of about 5600 households were undertaken at baseline and roughly 2 years later . Pregnant women and mothers of children younger than 3 years old were asked about use of health services ( primary outcome ) and coverage of interventions such as immunisation and growth monitoring  ( secondary outcome ) . Reports were supplemented with data from children 's health cards and government service utilisation data . Analysis was by mixed effects regression , accounting for the municipality-level r and omisation . FINDINGS The household-level intervention had a large impact ( 15 - 20 percentage points ; p<0.01 ) on the reported coverage of antenatal care and well-child check-ups . Childhood immunisation series could thus be started more opportunely , and the coverage of growth monitoring was markedly increased ( 15 - 21 percentage points ; p<0.01 . Measles and tetanus toxoid immunisation were not affected . The transfer of re sources to local health teams could not be implemented properly because of legal complications . INTERPRETATION Conditional payments to households increase the use and coverage of preventive health care interventions BACKGROUND Effective and scalable HIV prevention for adolescents in sub-Saharan Africa is needed . Cash transfers can reduce HIV incidence through reducing risk behaviours . However , questions remain about their effectiveness within national poverty-alleviation programmes , and their effects on different behaviours in boys and girls . METHODS In this case-control study , we interviewed South African adolescents ( aged 10 - 18 years ) between 2009 and 2012 . We r and omly selected census areas in two urban and two rural districts in two provinces in South Africa , including all homes with a resident adolescent . We assessed household receipt of state-provided child-focused cash transfers , incidence in the past year and prevalence of transactional sex , age-disparate sex , unprotected sex , multiple partners , and sex while drunk or after taking drugs . We used logistic regression after propensity score matching to assess the effect of cash transfers on these risky sexual behaviours . FINDINGS We interviewed 3515 participants ( one per household ) at baseline , and interviewed 3401 at follow-up . For adolescent girls ( n=1926 ) , receipt of a cash transfer was associated with reduced incidence of transactional sex ( odds ratio [ OR ] 0·49 , 95 % CI 0·26 - 0·93 ; p=0·028 ) , and age-disparate sex ( OR 0·29 , 95 % CI 0·13 - 0·67 ; p=0·004 ) , with similar associations for prevalence ( for transactional sex , OR 0·47 , 95 % CI 0·26 - 0·86 ; p=0·015 ; for age-disparate sex , OR 0·37 , 95 % CI 0·18 - 0·77 ; p=0·003 ) . No significant effects were shown for other risk behaviours . For boys ( n=1475 ) , no consistent effects were shown for any of the behaviours . INTERPRETATION National , child-focused cash transfers to alleviate poverty for households in sub-Saharan Africa can substantially reduce unsafe partner selection by adolescent girls . Child-focused cash transfers are of potential importance for effective combination strategies for prevention of HIV . FUNDING UK Economic and Social Research Council , South African National Research Foundation , Health Economics and AIDS Research Division at University of KwaZulu-Natal , South African National Department of Social Development , Claude Leon Foundation , John Fell Fund , Nuffield Foundation , and Regional Interagency Task Team for Children affected by AIDS-Eastern and Southern Africa BACKGROUND Many governments have implemented conditional cash transfer ( CCT ) programmes with the goal of improving options for poor families through interventions in health , nutrition , and education . Families enrolled in CCT programmes  receive cash in exchange for complying with certain conditions : preventive health requirements and nutrition supplementation , education , and monitoring design ed to improve health outcomes and promote positive behaviour change . Our aim was to disaggregate the effects of cash transfer from those of other programme components . METHODS In an intervention that began in 1998 in Mexico , low-income communities ( n=506 ) were r and omly assigned to be enrolled in a CCT programme  ( Oportunidades , formerly Progresa ) immediately or 18 months later . In 2003 , children ( n=2449 ) aged 24 - 68 months who had been enrolled in the programme their entire lives were assessed for a wide variety of outcomes . We used linear and logistic regression to determine the effect size for each outcome that is associated with a doubling of cash transfers while controlling for a wide range of covariates , including measures of household socioeconomic status . FINDINGS A doubling of cash transfers was associated with higher height-for-age Z score ( beta 0.20 , 95 % CI 0.09 - 0.30 ; p<0.0001 ) , lower prevalence of stunting ( -0.10 , -0.16 to -0.05 ; p<0.0001 ) , lower body-mass index for age percentile ( -2.85 , -5.54 to -0.15 ; p=0.04 ) , and lower prevalence of being overweight ( -0.08 , -0.13 to -0.03 ; p=0.001 ) . A doubling of cash transfers was also associated with children doing better on a scale of motor development , three scales of cognitive development , and with receptive language . INTERPRETATION Our results suggest that the cash transfer component of Oportunidades is associated with better outcomes in child health , growth , and development There is promising recent evidence that poverty-targeted social cash transfers have potential to improve maternal health outcomes ; however , questions remain surrounding design features responsible for impacts . In addition , virtually no evidence exists from the African region . This study explores the impact of Zambia 's Child Grant Program  on a range of maternal health utilization outcomes using a r and omized design and difference-in-differences multivariate regression from data collected over 24 months from 2010 to 2012 . Results indicate that while there are no measurable program impacts among the main sample , there are heterogeneous impacts on skilled attendance at birth among a sample of women residing in households having better access to maternal health services . The latter result is particularly interesting because of the overall low level of health care availability in program areas suggesting that dedicated program design or matching supply-side interventions may be necessary to leverage unconditional cash transfers in similar setting s to impact maternal health
The quality of evidence on the effect of financial incentives on breastfeeding practice s was low but seems to indicate a potential positive impact on receiving colostrum , early initiation of breastfeeding , exclusive breastfeeding and mean duration of exclusive breastfeeding .
There is no effect of financial incentives on immunization coverage although there was moderate quality evidence of conditional cash transfers leading to a small but non-significant increase in coverage of age-appropriate immunization .
Conclusions Financial incentives may have potential to promote increased coverage of several important child health interventions , but the quality of evidence available is low .
The more pronounced effects seem to be achieved by programs that directly removed user fees for access to health services .
Some indication of effect were also observed for programs that conditioned financial incentives on participation in health education and attendance to health care visits .
This finding suggest that the measured effect may be less a consequence of the financial incentive and more due to conditionalities addressing important informational barriers
Background Financial incentives are widely used strategies to alleviate poverty , foster development , and improve health .
Cash transfer programs , microcredit , user fee removal policies and voucher schemes that provide direct or indirect monetary incentives to households have been used for decades in Latin America , Sub-Saharan Africa , and more recently in Southeast Asia .
Until now , no systematic review of the impact of financial incentives on coverage and uptake of health interventions targeting children under 5 years of age has been conducted .
The objective of this review is to provide estimates on the effect of six types of financial incentive programs : ( i ) Unconditional cash transfers ( CT ) , ( ii ) Conditional cash transfers ( CCT ) , ( iii ) Microcredit ( MC ) , ( iv ) Conditional Microcredit ( CMC ) , ( v ) Voucher schemes ( VS ) and ( vi ) User fee removal ( UFR ) on the uptake and coverage of health interventions targeting children under the age of five years .
