Relationship of people across an international border based on an isonymy analysis across the German–Danish frontier
Authors: Boldsen Jesper , Lasker Gabriel W. 
Published: July 2008

SummaryUsing lists of names of male personal telephone subscribers, isonymy was calculated within and between 29 contiguous areas in a north-to-south line extending 210 km south of Grindsted, Denmark. Each area shared some surname(s) with every other area. Isonymy was high across both the present and past borders of Denmark with Germany and was consistently lower in areas beyond 160 km south of Grindsted. Relative isonymy between areas was also smaller on average south of the present border than north of it, and smaller still for pairs of areas spanning the border. This is partly accounted for by decreases in isonymy with distance, but the slope of the logistic regression on distance is greater for the northern moiety than the southern one. Most of these findings can be traced to the influence of common surnames ending in ‘sen’, the distribution of which tends to correlate highly with isonymy. Such surnames tend to be of recent origin and to be very frequent and hence highly polygenic. Thus much of the heterogeneity is explained by surname history rather than genetic heterogeneity.
Intrauterine devices: learning from the past and looking to the future
Authors: Petta Carlos Alberto , McPheeters Melissa , Chi I-Cheng 
Published: July 2008

SummaryThis paper reviews the historical development of the IUD, describing the challenges and successes, and attempts to offer a balanced perspective for family planning service workers today. Modern IUDs are an important component of family planning services and an excellent contraceptive choice for properly screened women, providing contraception that is safe, effective, long lasting and cost effective. Potential research strategies for the future are also discussed.
Contributions of the proximate determinants to fertility change in Botswana
Authors: Letamo Gobopamang 
Published: July 2008

SummaryThis study uses Bongaarts' model to examine the relative contributions of three proximate determinants (non-marriage, contraceptive use and postpartum infecundability) to fertility change using data from the 1984 and 1988 Botswana Family and Health Surveys. Breast-feeding is shown to be the most important proximate determinant of fertility, followed by contraceptive use, and finally non-marriage, both in 1984 and 1988. However, contraceptive use increased between 1984 and 1988, leading to fertility decline over this period. Marriage is the least important proximate determinant of fertility, probably due to the high prevalence of premarital childbearing. Other factors such as induced abortion could have played a major role in the fertility decline but their effect could not be estimated due to lack of accurate data.
Social and economic factors related to breast-feeding durations in Tanzania
Authors: Hinde P. R. Andrew , Mturi Akim J. 
Published: July 2008

SummarySome social and economic factors related to breast-feeding durations in Tanzania are analysed using current status data taken from the 1991–92 Tanzanian Demographic and Health Survey. Proportional hazards and proportional odds models are estimated. The results show that breast-feeding durations vary according to the region of residence of the mother and child (and whether they are living in a rural or an urban area), the age of the mother at the time of the birth, the order of the birth, and the mother's religion.
Using a mixture model to detect son preference in Vietnam
Authors: Haughton Dominique , Haughton Jonathan 
Published: July 2008

SummarySon preference is strong in Vietnam, according to attitudinal surveys and studies of contraceptive prevalence and birth hazards. These techniques assume a single model is valid for all families, but it is more plausible that son preference is found for some, but not all, families. Heterogeneous preferences may be addressed with a mixture model. This paper specifies and estimates a two-Weibull regression model, applied to the interval between the second and third births. The data come from the Vietnam Living Standards Survey of 1992–93. Applying information criteria, graphs, and martingale-based residuals, the two-Weibull model is found to fit better than a one-Weibull model. Roughly half of parents have son preference and, curiously, a propensity for fewer children. The other group has more children, no son preference, and is colourless in the sense that the birth interval is difficult to predict on the basis of the regressors used.
A healthy body and a healthy mind: the relationship between ill-health and cognitive function in school-age children
Authors: Nokes C. 
Published: July 2008

Health of school age children and the Partnership for Child DevelopmentUntil recently, health programmes in developing countries have focused on infant survival and on the health of adolescents and, consequently, the health concerns of children of school age, falling between the ages of infancy and adolescence, have been neglected. The World Bank Development Report of 1993, stated a need to move beyond the focus on survival and to capture the concept that community health depends on the quality of life and opportunities for development. In response, the Partnership for Child Development was set up in 1992 to address the problem of ill-health among school-age children in the developing world.
The influence of early diet on later development
Authors: Morley Ruth 
Published: July 2008

SummaryThe possibility that early nutrition has long term consequences in man has been much debated. There have been limited opportunities to perform formal randomised studies on the effect of early nutrition in man and many studies have been flawed by problems with study design. Infants born preterm are a special group. At the start of this study in 1982 evidence on which to base choice of diet was inconsistent and related only to short term outcome, and diets available for such babies differed greatly in nutrient content. In this group it was both ethical and practical to conduct a formal, randomised trial of early diet and outcome and the results were clearly needed for management decisions.A long term prospective outcome study was undertaken on 926 preterm infants randomly assigned to the diet received in the neonatal period. Surviving children have been followed at 9 months, 18 months and now 7½–8 years of age. The findings suggest that children fed a nutrient supplemented preterm formula perform better than those fed a standard formula milk, and also that human milk may contain factors which promote brain growth or development. Outcome data from the randomised trials show that a very brief period of dietary manipulation (on average for the first 4 weeks of life) influences later development.

Demographic perspectives on China and India
Authors: Adlakha Arjun , Banister Judith 
Published: July 2008

SummaryThis paper compares levels and trends of population growth rates, age and sex composition, mortality, and fertility including family planning practices in the world's two most populous countries, China and India. Both countries are undergoing demographic transition but China is nearer than India to achieving a stationary population. Fertility in China has declined below replacement level while in India it is nearly one and a half children per woman above replacement level. Both countries have achieved large reductions in mortality but life expectancy at birth in China is currently about 10 years longer than in India. Both countries have young populations but China will precede India in the aging of population structure during the 21st century.
Infant and child mortality levels and trends in Bangladesh
Authors: Kabir M. , Chowdhury Rafiquel Islam , Amin Ruhul 
Published: July 2008

SummaryInfant and child mortality levels and trends in Bangladesh are examined using data from the 1989 Bangladesh Fertility Survey. Both infant and child mortality declined from the mid 1970s but infant mortality declined more quickly. The level of infant mortality in 1989 was around 100 per 1000 live births while child mortality (5q) was 200 per 1000 live births. Life table analysis confirms the change in infant and child mortality.The decline in infant mortality is attributed to the introduction of improved public health measures and access to maternal and child health services.
Inter-individual and seasonal weight variation in rural Nepali women
Authors: Panter-Brick C. 
Published: July 2008

SummaryChanges in body weight were examined for non-pregnant women in rural Nepal, using 183 anthropometric measures between the early winter and monsoon seasons in 1982, 1982–83, 1990–91 and 1993. The women gained weight when work loads decreased after the monsoon, but despite substantial changes in total energy expenditure, which were out of phase with changes in food intake, seasonal changes were small, averaging only up to 2.6% of initial body weight.There were notable differences between individual women, changes in body weight ranging from-5·6 kg to 4·8 kg. Weight change was examined with respect to lactation status, age, body mass index, mid upper arm circumference and skinfolds as well as total energy expenditure and intake. Non-lactating women, very thin women and women aged under 25 years gained more weight than their counterparts, both before and after the monsoon. Data for a sub-sample in 1982–83 indicated that women who maintained high physical activity levels throughout the year were less prone to weight loss than women whose activity fluctuated between seasons. Initial energy reserves, age-related maturation factors, levels of physical activity and energy intake combine to produce the notable inter-individual variation in body weight changes observed in this population.
Perceptions of symptoms of severe childhood malaria among Mijikenda and Luo residents of Coastal Kenya
Authors: Mwenesi H. A. , Harpham T. , Marsh K. , Snow R. W. 
Published: July 2008

SummaryEffective community based malaria control programmes require an understanding of current perceptions of malaria as a disease and its severe manifestations. Quantitative and qualitative surveys of mothers on the Kenyan Coast suggest that fever is conceptualised in biomedical terms whereas the aetiology of severe malaria is perceived to be of more complex cultural origin. This is reflected in the treatments sought for convulsions. The results are discussed in the context of ethnographic factors. To be effective, future health information programmes must take cultural beliefs into account.
Premature weaning in East Bhutan: only if mother is pregnant again
Authors: Bohler Erik , Bergström Staffan 
Published: July 2008

SummaryThe relationship between breast-feeding and subsequent pregnancy in East Bhutan is examined, against the background of local attitudes to family planning. Ninety-eight mothers who had given birth 30–36 months earlier were interviewed. Semisolid supplementary feeding was introduced at a median age of 3 months. Median total duration of breast-feeding was 28 months, and day and night breast-feeding on demand was continued throughout. Median duration of postpartum amenorrhoea was 12 months, and was associated with the timing of the introduction of supplementary foods.There was a significant association between the occurrence of a subsequent pregnancy and early termination of breast-feeding. The relationships between breast-feeding pattern and pregnancy interval are complex, and their relative influence changes with time. During the first year postpartum, infertility during lactational amenorrhoea is important. During the second year there is a strong negative effect on lactation from the next pregnancy. The only important reason for ceasing to breast-feed within 2 years seems to be a new pregnancy.
Is menopause withering away?
Authors: Topo Paivi , Hemminki Elina 
Published: July 2008

SummaryMenopause (cessation of menstruction) and the period surrounding it (climacterium) are often defined retrospectively by asking a woman the date of her last menstrual period (LMP). Based on a survey of 2000 women aged 45–64 in 1989 in Finland, this study examines (1) the relation between these definitions and women's own definitions of their climacteric status and of the cessation of menstruction and (2) the effect of menopausal and postmeno pausal hormone therapy and hysterectomy on the definition of menopause and climacterium. Agreement of the woman's own definition of her climacteric status and interval since LMP was 25% among current hormone users, 41% among hysterectomised women and 64% among those who were neither currently using hormones nor had been hysterectomised. Current hormone users defined the climacteric phase as longer than their LMP suggested. Current hormone use and hysterectomy had little effect on reported final cessation of menstrual periods. It is concluded that hysterectomy and hormone therapy shape women's thinking about the end of reproductive life, blur the concepts of menopause and postmenopause and confuse the measurement of age at menopause.
The adaptive significance of social synchronisation of ultradian behaviour cycles: a computer model
Authors: Meier-Koll A. , Bohl E. , Schardl B. , Novacek F. 
Published: July 2008

SummaryDaily behaviour patterns in a hunter–gatherer community of Colombian Indians show that individual activities are regulated by ultradian behaviour cycles of about 2 hr and that these cycles can be synchronised by social interaction. A computer model was developed which simulated an artificial community and generated dynamic portraits of locomotor activity and social aggregation similar to those of the observed community of Colombian Indians. Social phase-locking of ultradian behaviour cycles occurred, contributing to the safety of group members and their economy of effort in gathering and related activities. Social synchronisation of ultradian behaviour cycles may also have occurred in early hominid groups.
Sex linked versus autosomal inbreeding coefficient in close consanguineous marriages in the Basque country and Castile (Spain): genetic implications
Authors: Calderón R. , Morales B. , Peña J. A. , Delgado J. 
Published: July 2008

SummaryPedigree structures of 161 uncle/niece-aunt/nephew and 4420 first cousin consanguineous marriages registered during the 19th and 20th centuries in two large and very different Spanish regions have been analysed and their genetic consequences evaluated. The frequencies of the different pedigree subtypes within each degree of relationship were quite similar in both populations despite significant heterogeneity in inbreeding patterns. The mean X-linked inbreeding coefficient (Fx) for each type of cousin mating was calculated and compared to that expected for autosomal genes (F). The effect of genealogical structure on theFx/Fradio was compared to different cultural populations worldwide. Preferentiality and avoidance of close consanguinity along with specific types of pedigrees are discussed on the basis of premarital migration and sociocultural rules still deeply rooted in certain human groups. By admitting that the observedFxcoefficient is usually higher thanFin most human populations some remarks have been made in terms of population genetic risk.
Birth spacing and infant and early childhood mortality in a high fertility area of Bangladesh: age-dependent and interactive effects
Authors: Alam Nurul 
Published: July 2008

SummaryTo examine the effects of birth spacing on early childhood mortality, 3729 singleton births in 1983–84 were followed for 3 years in rural Bangladesh. Logistic regression analyses were used to assess whether the survival of older siblings modifies the effect of preceding birth intervals and to see if the effects of preceding and succeeding birth intervals are inter-related, controlling for the effects of sex of the child, mother's age and household economic status. With the exception of the neonatal period, birth spacing effects were highly significant. A preceding birth interval of <15 months was associated with a greater mortality risk in the post-neonatal period for children with an older sibling who survived infancy. However, a short preceding birth interval did not adversely affect post-neonatal mortality if the older sibling died in infancy. Neonatal and post-neonatal deaths were higher if older siblings had died in respective age intervals. A pregnancy interval of <12 months after childbirth raised the risk of death at ages 1–2 years considerably if the child was born after a short birth interval (<15 months). The results suggest that the high mortality risks of closely spaced children are due to sibling competition for parental resources.
Australian trends in mortality by socioeconomic status using NSW small area data, 1970–89
Authors: Quine Susan , Taylor Richard , Hayes Lillian 
Published: July 2008

SummaryThis ecological study examines trends in socioeconomic differentials in mortality in New South Wales, Australia, over a 20-year period (1970–89). The proportion unskilled was used as the indicator of socioeconomic status and its selection justified. Using census data aggregated by Local Government Area, the relationship between mortality and socioeconomic status was examined using quintiles based on the proportion unskilled in the population. Local Government Areas were also sorted into quintiles using mortality rates (0–74 years) to describe change in mortality differentials over time. Socioeconomic differentials were more evident in the relatively homogeneous Local Government Areas within the Sydney Statistical Division than in the remaining NSW Statistical Divisions which are more heterogeneous and predominantly rural. Although there has been an overall decline in mortality for males and females, and for high and low status groups, over this period the relative socioeconomic differentials have not declined. For the most recent period (1985–89) there appears to be some widening of differentials for males. The NSW state trends are generally similar to those reported for Britain and for other industrialised countries, suggesting that this is a common trend and that policies to reduce inequalities have not been effective.
Antecedents of Adolescent Pregnancy
Authors: Wilson Fiona 
Published: July 2008

SummaryThe recognition of which girls are at risk of becoming pregnant before the age of 16 years is of interest to legal, educational, social and medical services. In this paper a large amount of data, available for a total population of schoolgirls, has been used to show that prediction is indeed possible. It was found that compared to a group of girls matched on a number of sociodemographic characteristics, those who became pregnant during adolescence were more likely to have been academic underachievers at age 11, to have made an appearance in a juvenile court, and to have been referred to a child guidance or psychiatric clinic at an early age. Difficulties over matching also suggest that they are more likely to have five or more siblings, to be illegitimate and to have mothers who were themselves teenagers at the time of their daughter's birth.
Fertility of Migrant Women in Australia
Authors: Yusuf Farhat , Eckstein Gary 
Published: July 2008

SummaryThis paper examines the current fertility (1971–72) of migrant women in Australia, in order to compare the fertility levels and patterns prevalent among migrants from nine selected countries with those of the Australian born women. Birth registration data have been mainly used in the analysis.Three main points emerge. Among the married women there were few differences in fertility regardless of the country of birth. A major exception was the somewhat higher fertility levels among the southern European migrants. Extramarital fertility seemed to vary substantially between different migrant groups: New Zealanders had the highest and the Italians and Greeks had the lowest levels. There were major differences in the proportion of women married among the various migrant groups; again the southern Europeans had highest proportions married. Comparison of the reproductive behaviour of migrants with their counterparts in the countries of origin showed that the southern European migrants in Australia had higher fertility rates than those prevalent in their countries of origin.
Abortion in India, with Particular Reference to West Bengal
Authors: Dutta Ranajit 
Published: July 2008

SummaryInduced abortion has a long history in India. It occurs in village society, although the rate is relatively low. Socioeconomic and demographic characteristics of women having legal abortions are presented for a national, a West Bengal state, and a West Bengal local sample. A series of illegal abortions (1969) prior to the legalization of abortion in West Bengal is compared with more recent experience (1977–78) of legal abortion.Clinical facilities for meeting the demand for abortion are still inadequate. Reasons are given for predicting that the demand for legal abortion will continue to rise. Currently only 6% of legal abortions are by vacuum aspiration and nearly one-quarter by hysterotomy and hysterectomy. Greater provision needs to be made for the safer early abortions.
A Demographic Study of Mirpur: A Village in Coastal Midnapore District, West Bengal
Authors: Basu Amitabha , Gupta Ranjan , Bhattacharya Kalyan K. 
Published: July 2008

SummaryMirpur is a small village of 320 individuals in coastal Midnapore district, West Bengal, the inhabitants of which claim partial Portuguese ancestry. The demographic data collected in Mirpur are reported here. The age structure of the population suggests a growing population trend, but a constriction at the base of the pyramid indicates a recent decline of fertility. The completed family size, net reproductive index and total fertility rate are also compatible with high growth rate, but the age-specific fertility rates are lower in the younger than in the older women. The infant mortality rate is low in general, and is lower in the offspring of the younger women. The Mirpurians suffer from protein-calorie malnutrition and heavy intestinal parasitic load. The possible relationships among high fertility, malnutrition and high parasitic load are discussed.
