SummaryOccult hepatitis B infection (OBI) is characterized by serum hepatitis B surface antigen (HBsAg) negative and hepatitis B virus (HBV) DNA positive (HBsAg‐/HBV DNA+). Occult hepatitis B infection in community‐based populations has been scarcely investigated, and OBI outcomes remain unclear, especially in Wuwei, a region located in Northwest China. This region is one of the areas in China that has the highest prevalence of chronic HBV infection. A prospective study was performed in the general population of 2 towns of Wuwei from June 2011 to May 2014. A questionnaire was used to collect demographic and medical data, and serum samples were collected from the participants and stored until analysis. DNA was detected using quantitative PCR (qPCR) or nested PCR, the HBV DNA from HBV DNA‐positive or possible positive (below the detection limit) subjects was extracted and amplified by nested PCR, and the PCR products were sequenced. Sequence analysis was performed using the Mega 6.0 program and CLC sequence viewer software. Hepatitis B virus DNA was detected in 90 of 3,080 HBsAg‐negative subjects, and the prevalence of OBI in the study population was 2.92% (90/3,080, 95% CI: 2.33%‐3.51%). Hepatitis B virus genomes in 51 of 80 objects (63.75%) contained mutations in the “a” determinant of HBsAg. After 2 years follow‐up, 42 of 90 HBV DNA of OBI subjects remained positive, and the natural clearance rate of OBI subjects was 53.3%. Occult hepatitis B infection prevalence in this cohort was much lower than chronic HBV infection in the same region. HBV DNA was cleared in most OBI subjects during the 2 year period. Our data suggest that some OBI may represent a late stage of resolving the HBV infection process.

AbstractThis paper applies an implementation framework, based on a behavior change model, to compare four case studies of complementary feeding programs. It aims to expand our understanding of how to design and implement behavior change interventions aimed at improving complementary feeding practices. Four programs met the selection criteria of scale and documented improvements: Bangladesh, Malawi, Peru, and Zambia. We examined commonalities and differences in the design and implementation of social and behavior change approaches, use of program delivery platforms, challenges encountered, and lessons learned. We conclude that complementary feeding practices, in particular dietary diversity, can be improved rapidly in a variety of settings using available program platforms if interventions focus on specific constraints to food access and use effective strategies to encourage caregivers to prepare and feed appropriate foods. A five‐step process is presented that can be applied across a range of complementary feeding programs to strengthen their impacts.

AbstractAgriculture and food systems play a central role in nutrition by supplying nutritious, healthy and affordable foods. When integrated with nutrition education for behaviour change, agricultural interventions that supply diverse affordable foods from all food groups have great scope for improving young child and family diets. In 2014, process reviews were conducted in Cambodia and Malawi of food security projects that provided agricultural support and community‐based nutrition education on improved infant and young child feeding (IYCF). In both countries, household visits were carried out with mothers/caregivers, and interviews and Focus Group Discussions (FGDs) were conducted with purposively selected project stakeholders (53 in Cambodia, 170 in Malawi), including government staff from the agriculture and health sectors. Results highlight that adoption of improved IYCF practices was facilitated by participation in nutrition education and practical cooking sessions, and supportive family and community structures. Barriers faced by families and caregivers were identified, such as women's workload and lack of access to high quality foods, namely fruits, vegetables, legumes, nuts and animal source foods. Implementation challenges regarding coordination of cross‐sectoral targeting strategies and capacities of extension services to sustain community‐based IYCF nutrition education need to be addressed to improve programme effectiveness and impact. The project lessons from Cambodia and Malawi are useful for integrated agriculture‐IYCF nutrition education programmes to help ensure better young child nutrition outcomes.

AbstractThe availability and consumption of commercially produced foods and beverages have increased across low‐income and middle‐income countries. This cross‐sectional survey assessed consumption of commercially produced foods and beverages among children 6–23 months of age, and mothers' exposure to promotions for these products. Health facility‐based interviews were conducted among 218 randomly sampled mothers utilizing child health services in Dakar, Senegal; 229 in Dar es Salaam, Tanzania; 228 in Kathmandu Valley, Nepal; and 222 in Phnom Penh, Cambodia. In the day prior to the interview, 58.7% of 6–23‐month‐olds in Dakar, 23.1% in Dar es Salaam, 74.1% in Kathmandu Valley, and 55.0% in Phnom Penh had consumed a commercially produced snack food. In the previous week, the majority of children in Dakar (79.8%), Kathmandu Valley (91.2%), and Phnom Penh (80.6%) had consumed such products. Consumption of commercially produced sugar‐sweetened beverages was noted among 32.0% of Phnom Penh, 29.8% of Dakar, 23.1% of Dar es Salaam, and 16.2% of Kathmandu Valley children. Maternal education was negatively associated with commercial snack food consumption in Dakar and Kathmandu Valley. Children of Phnom Penh mothers in the lowest wealth tercile were 1.5 times more likely to consume commercial snack food products, compared to wealthier mothers. These snack consumption patterns during the critical complementary feeding period demand attention; such products are often high in added sugars and salt, making them inappropriate for infants and young children.
Government information systems to monitor complementary feeding programs for young children
Authors: Jefferds Maria Elena D. 
Published: October 2017

AbstractAccelerating progress to improve complementary feeding of young children is a global priority. Strengthening monitoring through government information systems may increase the quality and implementation of infant and young child feeding (IYCF) programs. Monitoring is necessary for the effective implementation of programs as it allows program managers to assess program performance, identify problems, and take corrective action. Program descriptions and conceptual models explain how program inputs and activities should lead to outputs and outcomes, and ultimately public health impact; thus, they are critical tools when designing effective IYCF programs and monitoring systems as these descriptions and conceptual models form the basis for the program and are key for developing the monitoring system, indicators, and tools. Despite their importance, many programs do not have these documented, nor monitoring plans, limiting their ability to design effective programs and monitoring systems. Once in place, it is important to periodically review the monitoring system to confirm it still appropriately meets stakeholder needs and the data are being used to inform decision‐making, and to make program adjustments as the monitoring focus, resources, or capacity may change during the program lifecycle. Including priority indicators of IYCF practices and counseling indicators in the government information systems may strengthen IYCF programs when the indicators are contextualized to the government IYCF program, capacity, and setting, and the indicators are used for decision‐making and program improvement.

AbstractWe assessed India's readiness to deliver infant and young child feeding (IYCF) interventions by examining elements related to policy, implementation, financing, and evidence. We based our analysis on review of (a) nutrition policy guidance and program platforms, (b) published literature on interventions to improve IYCF in India, and (c) IYCF program models implemented between 2007 and 2012. We find that Indian policies are well aligned with global technical guidance on counselling interventions. However, guidelines for complementary food supplements (CFS) need to be reexamined. Two national programs with the operational infrastructure to deliver IYCF interventions offer great potential for scale, but more operational guidance, capacity, and monitoring are needed to actively support delivery of IYCF counselling at scale by available frontline workers. Many IYCF implementation efforts to date have experimented with approaches to improve breastfeeding and initiation of complementary feeding but not with improving diet diversity or the quality of food supplements. Financing is currently inadequate to deliver CFS at scale, and governance issues affect the quality and reach of CFS. Available evidence from Indian studies supports the use of counselling strategies to improve breastfeeding practices and initiation of complementary feeding, but limited evidence exists on improving full spectrum of IYCF practices and the impact and operational aspects of CFS in India. We conclude that India is well positioned to support the full spectrum of IYCF using existing policies and delivery platforms, but capacity, financing, and evidence gaps on critical areas of programming can limit impact at scale.
Harnessing private sector expertise to improve complementary feeding within a regulatory framework: Where is the evidence?

AbstractGlobal recognition that the complex and multicausal problems of malnutrition require all players to collaborate and to invest towards the same objective has led to increased private sector engagement as exemplified through the Scaling Up Nutrition Business Network and mechanisms for blended financing and matched funding, such as the Global Nutrition for Growth Compact. The careful steps made over the past 5 to 10 years have however not taken away or reduced the hesitation and scepticism of the public sector actors towards commercial or even social businesses. Evidence of impact or even a positive contribution of a private sector approach to intermediate nutrition outcomes is still lacking. This commentary aims to discuss the multiple ways in which private sector can leverage its expertise to improve nutrition in general, and complementary feeding in particular. It draws on specific lessons learned in Bangladesh, Côte d'Ivoire, India, Indonesia, and Madagascar on how private sector expertise has contributed, within the boundaries of a regulatory framework, to improve availability, accessibility, affordability, and adequate use of nutritious foods. It concludes that a solid evidence base regarding the contribution of private sector to complementary feeding is still lacking and that the development of a systematic learning agenda is essential to make progress in the area of private sector engagement in nutrition.

AbstractAge‐appropriate complementary feeding practices are far from optimal among low‐ and middle‐income countries with available data. The evidence on the association between feeding practices and linear growth is mixed. We sought to systematically examine the association between two indictors of dietary quality—dietary diversity and animal source food (ASF) consumption (WHO, 2008)—and stunting (length‐for‐age z‐score) employing existing data from 39 Demographic and Health Surveys. Data on 74,548 children aged 6–23 months were pooled and multiple logistic regression models, adjusting for child, maternal, and household characteristics, employed to assess the association between dietary quality and stunting. Stratified models by child age and by World Bank country‐income classifications (World Bank, 2015) were also applied. Children aged 6–23 months consuming zero food groups in the previous day had a 1.345 higher odds of being stunted when compared to the reference group (≥5 food groups); those who did not consume any ASF in the previous day had a 1.436 higher odds of being stunted compared to children consuming all three types of ASF (egg, meat, and dairy). We estimated that 2,629 cases of stunting would have been averted (12.6% of those stunted) among the population studied if all children had consumed five or more food groups. Outcomes by country‐income groupings showed larger associations of diet diversity and ASF consumption for upper‐ and lower‐middle income countries compared to low‐income countries. In summary, dietary diversity and ASF consumption were associated with stunting, with associations varying by stratified groups.
Evaluation of programs to improve complementary feeding in infants and young children
Authors: Frongillo Edward A. 
Published: October 2017

AbstractEvaluation of complementary feeding programs is needed to enhance knowledge on what works, to document responsible use of resources, and for advocacy. Evaluation is done during program conceptualization and design, implementation, and determination of effectiveness. This paper explains the role of evaluation in the advancement of complementary feeding programs, presenting concepts and methods and illustrating them through examples. Planning and investments for evaluations should occur from the beginning of the project life cycle. Essential to evaluation is articulation of a program theory on how change would occur and what program actions are required for change. Analysis of program impact pathways makes explicit the dynamic connections in the program theory and accounts for contextual factors that could influence program effectiveness. Evaluating implementation functioning is done through addressing questions about needs, coverage, provision, and utilization using information obtained from process evaluation, operations research, and monitoring. Evaluating effectiveness is done through assessing impact, efficiency, coverage, process, and causality. Plausibility designs ask whether the program seemed to have an effect above and beyond external influences, often using a nonrandomized control group and baseline and end line measures. Probability designs ask whether there was an effect using a randomized control group. Evaluations may not be able to use randomization, particularly for programs implemented at a large scale. Plausibility designs, innovative designs, or innovative combinations of designs sometimes are best able to provide useful information. Further work is needed to develop practical designs for evaluation of large‐scale country programs on complementary feeding.

AbstractAdequate nutrient intake is a prerequisite for achieving good nutrition status. Suboptimal complementary feeding practices are a main risk factor for stunting. The need for systematic and user‐friendly tools to guide the planning, implementation, monitoring, and evaluation of dietary interventions for children aged 6–23 months has been recognized. This paper describes five tools, namely, ProPAN, Optifood, Cost of the Diet, Fill the Nutrient Gap, and Monitoring Results for Equity System that can be used in different combinations to improve situation analysis, planning, implementation, monitoring, or evaluation approaches for complementary feeding in a particular context. ProPAN helps with development of strategies and activities designed to change the behaviours of the target population. Optifood provides guidance for developing food‐based recommendations. The Cost of the Diet can provide insight on economic barriers to accessing a nutritious and balanced diet. The Fill the Nutrient Gap facilitates formulation of context‐specific policies and programmatic approaches to improve nutrient intake, through a multistakeholder process that uses insights from linear programming and secondary data. The Monitoring Results for Equity System helps with analysis of gaps, constraints, and determinants of complementary feeding interventions and adoption of recommended practices especially in the most vulnerable and deprived populations. These tools, and support for their use, are readily available and can be used either alone and/or complementarily throughout the programme cycle to improve infant and young child‐feeding programmes at subnational and national levels.
Complementary feeding practices for infants and young children in South Asia. A review of evidence for action post‐2015
Authors: Aguayo Víctor M. 
Published: October 2017

AbstractSome 37% (~64 million) South Asian children under 5 years are stunted. Most stunting occurs during the complementary feeding period (6–23 months). Our objective was to (a) characterize complementary feeding practices in South Asia and (b) review the effectiveness of information, education, and counselling (IEC) interventions aiming to improve complementary feeding in South Asia. We conducted a comprehensive review of (a) the latest nationally representative survey data and (b) peer‐reviewed interventions (January 1990 to December 2015) that used IEC as the main strategy to improve complementary feeding. The analytical sample included 30,966 children aged 6–23 months. Foods made from grains are the main complementary food (76.8% of children). Only 33.2% of children are fed fruits and vegetables rich in vitamin A and a mere 17.1% are fed complementary foods containing meat, fish, poultry and/or eggs. Timely introduction, minimum meal frequency, minimum dietary diversity, and minimum acceptable diet were estimated at 57.4%, 47.7%, 33.0%, and 20.5%, respectively. The evidence on the effectiveness of IEC interventions is limited in quantity, quality, and scale. The 12 intervention studies that met the inclusion criteria indicate that IEC interventions delivered by many types of primary care workers/community resource persons using multiple contact opportunities improved the timeliness, frequency, diversity, and/or adequacy of complementary feeding. However, acceptability, availability, and affordability seem to constrain improvements in diet diversity, particularly foods of animal origin. The small size of most intervention studies and the training and/or supervision intensity of counsellors raise concerns about the potential for scale and/or sustainability of some of the interventions reviewed.
Emerging issues in complementary feeding: Global aspects
Authors: Michaelsen Kim F. , Grummer‐Strawn Laurence , Bégin France 
Published: October 2017

AbstractThe complementary feeding period (6–24 months) is a window of opportunity for preventing stunting, wasting, overweight, and obesity and for improving long‐term development and health. Because WHO published its guiding principles for complementary feeding in 2003, new knowledge and evidence have been generated in the area of child feeding. The aim of this paper is to highlight some of the emerging issues in complementary feeding and potential implications on the guidelines revision.Evidence on the effect of the quality and quantity of protein and fat intake on child growth during the complementary feeding period is summarized. The increased availability of sugar‐containing beverages and unhealthy snack foods and its negative effect on young child's diet is described. Negative effects of nonresponsive feeding and force feeding are also discussed, although few scientific studies have addressed these issues.There are several emerging research areas that are likely to provide a better understanding of how complementary feeding influences growth, development, and health. These include the effect of the young child's diet on body composition, gastrointestinal microbiota, and environmental enteric dysfunction. However, at present, findings from these research areas are not likely to influence guidelines.Several emerging issues will be relevant to address when complementary feeding guidelines will be updated. With the increasing prevalence of obesity globally, it is important that guidelines on complementary feeding address both prevention of undernutrition and prevention of overweight, obesity, and noncommunicable diseases later in life.
Household food insecurity and children's dietary diversity and nutrition in India. Evidence from the comprehensive nutrition survey in Maharashtra

AbstractWe analyse data from the 2012 Comprehensive Nutrition Survey in the State of Maharashtra, India, which surveyed 2,630 households. This is a unique dataset because in addition to nutritional status of mothers and children, it has information on diets of women and children and household food security. This rich dataset allows us to address three issues: whether household food security predicts higher diet diversity in children aged 6–23 months; whether household food security predicts lower risk of undernutrition; and whether the lower risk of undernutrition in children who live in food secure households is mediated by improved diet diversity for children. We find that children from moderately food insecure and severely food insecure households are more likely to have lower diet diversity scores. We find that the odds of a child being severely stunted, severely underweight, or severely wasted are higher in severely food insecure households. After controlling for children's diet diversity, and other child, maternal and household characteristics, we find that household food security is no longer statistically associated with stunting, wasting, or underweight. However, diet diversity of children is statistically significantly associated with whether a child is stunted or underweight. Our results although not causal provide evidence for understanding the extent to which household food insecurity affects children's diet diversity and how both these factors affect nutrition outcomes in children. Our analysis informs Government of Maharashtra's and India's National Nutrition Mission in their efforts for formulating appropriate policies and programmes to address child undernutrition.
