The Journal of Biosocial Science regularly publishes papers addressing the social and cultural aspects of disease, sickness and well-being. Most of these papers attempt to understand the prevalence and distribution of disease and sickness within and between populations as well as local responses to biomedical interventions and public health policy more generally. They fall broadly within the remit of human ecology; and they embrace a ‘factorial’ model of disease in which social and cultural factors are deemed to be just one of a number of factors to be considered alongside a range of other factors. These include biological features of the infecting organism; nutritional factors; environmental factors; psychological factors; and genetic factors influencing susceptibility to disease at an individual and population level.

This work concerns the questions if and to what extent social variables past and present, and actual sports activity and nutritional and smoking habits, have an influence on body compartment indices, and how this differs between female and male medical students from Wrocław, Poland. Backward stepwise regression was applied to four dependent variables, i.e. Body Mass Index (BMI), %Fat Mass (%FM), Extracellular Water/Intracellular Water Index (100×ECW/ICW) and Body Cell Mass Index (BCMI=BCM/height2), and for eighteen independent variables including nutrition, parents’ social status, smoking and sports activity. Females ate meat less frequently and fruit and vegetables more often, and drank beer less frequently but milk more often than did male students. It seems that there exists some effect on fat accumulation resulting from difference in nutrition between females and males. The results may be interpreted in terms of a parental gender effect on body composition of children associated with different conditions of life and nutrition in childhood and youth for female and male students in Wrocław.

Premarital fertility, defined as fertility before first marriage, was found to be highly prevalent in Namibia. According to data from the 1992 and 2000 DHS surveys, the proportion of premarital births was 43% for all births, and 60% for the first birth. This seemed to be primarily due to a late mean age at first marriage (26·4 years) and low levels of contraception before first marriage. Data were analysed using a variety of demographic methods, including multiple decrement life table and multivariate logistic models. Major variations were found by ethno-linguistic groups: Herero and Nama/Damara had the highest levels of premarital fertility (above 60%); Ovambo and Lozi had intermediate levels of premarital fertility (around 40%); Kavongo and San appeared to have kept a more traditional behaviour of early marriage and low levels of premarital fertility (around 20%). The largest ethno-linguistic group, the Ovambo, were in a special situation, with fast increasing age at marriage and average level of premarital fertility. Whites and mixed races also differed, with Afrikaans-speaking groups having a behaviour closer to the average, whereas other Europeans had less premarital fertility despite an average age at marriage. Ethnic differences remained stable after controlling for various socioeconomic factors, such as urbanization, level of education, wealth, access to mass media, and religion. Results are discussed in light of the population dynamics and political history of Namibia in the 20th century.

Data from the District Level Household Survey (2002) conducted by the Reproductive and Child Health Project in India has been used to examine the impact of utilization of antenatal care services on improvement in maternal health in rural areas of Uttar Pradesh, India. Multilevel analysis shows that after controlling for other socioeconomic and demographic factors, utilization of antenatal care services may lead to the utilization of other maternal health related services such as institutional delivery, delivery assisted by trained professionals, seeking advice for pregnancy complications, and seeking advice for post-delivery complications. There is strong clustering of utilization of services within the primary sampling units (i.e. villages) and districts.

In Western industrialized countries, women report using health services, and certain medications, more often than do men. Often, analyses are based on data that exclude objective measures of morbidity and that come from cross-sectional surveys, which precludes the use of socioeconomic covariates that are endogenous to seeking care. Here, differences in objective cognitive and physical function, as well as differences in reporting on illness, propensity to seek care, and socioeconomic resources are expected to account for differences in care-seeking behaviour among women and men. This model is applied to the question of medication use in Ismailia, Egypt, using two waves of survey data and in-home tests of physical function from 896 adults aged 50 years and older. The results show that women use ‘modern’ medications more often than do men, and that differences between women and men in reported morbidity and disability, observed cognitive and physical function, and economic resources account for women’s greater use of medication. The findings underline a need for biosocial models to understand differences in women’s and men’s care-seeking behaviour in later life.

This paper uses multilevel modelling and Demographic and Health Survey data from five African countries to investigate the relative contributions of compositional and contextual effects of socioeconomic status and place of residence in perpetuating differences in the prevalence of malnutrition among children in Africa. It finds that community clustering of childhood malnutrition is accounted for by contextual effects over and above likely compositional effects, that urban–rural differentials are mainly explained by the socioeconomic status of communities and households, that childhood malnutrition occurs more frequently among children from poorer households and/or poorer communities and that living in deprived communities has an independent effect in some instances. This study also reveals that socioeconomic inequalities in childhood malnutrition are more pronounced in urban centres than in rural areas.

Uganda is invoked as a metaphor for a host of arguments and insights about HIV/AIDS. However, much of what has been asserted about the country is not based on the available evidence. This paper reviews findings by epidemiologists and anthropologists, and draws on the author’s experiences of researching in the country since the early 1980s. It comments on various myths about HIV/AIDS in Uganda, including myths about the origin and dissemination of the disease, about the links between HIV/AIDS and war, and about declining rates of infection. It shows that much less is known about Uganda than is commonly supposed, and it offers some alternative hypotheses for interpreting HIV prevalence and incidence data. In particular it draws attention to the importance of mechanisms for social compliance. It concludes by raising concerns about the current enthusiasm for provision of anti-retroviral drugs.

Using the matched wife–husband (763) sample from the data collected from Ogbomoso and Iseyin towns in Oyo State, Nigeria, this paper examines factors associated with couples’ fertility intention. The analysis used logistic regression models for predicting the effects of selected socioeconomic background characteristics on a couple’s fertility intention. Results indicate high levels of concurrence among husbands and wives on fertility intention. Where differences exist, husbands are more pronatalists than their wives. About 87% of pairs of partners reported similar fertility preferences. Of these couples, 59·5% wanted more children while only 27·8% reported otherwise. The logistic regression models indicated that a couple’s fertility intention was associated with age, education, place of residence, frequency of television-watching and number of living children. Therefore, programme interventions aimed at promoting fertility reduction in Nigeria should convey fertility regulation messages to both husbands and wives.

Two sample populations, one refugee and one resident, were studied. The frequencies of consanguineous marriages came out to be 49·8% and 55·4%, respectively, for the refugees and the residents. Caste endogamy was dominant both in the residents and the refugees. The mean coefficient of inbreeding was calculated to be 0·0303 for the refugee population and 0·0332 for the resident population samples. First cousin marriage was the dominant type of marriage in both samples; father’s brother’s daughter (FBD) marriage was more frequent among the refugees while mother’s brother’s daughter (MBD) marriage was more frequent among the residents. Education has no decreasing effect on the incidence of consanguineous marriages. A significant difference in the pattern of marriages in the refugees is observed after the Saur Revolution of 1979.

Intimate partner violence is widespread worldwide. While assumed to impact women’s ability to use contraceptive methods, few data are available to support this claim. In this study, eight focus group discussions were conducted to guide questionnaire development and to provide contextual information. Participants were women who were currently using the pill and women who had used the pill previously. In addition, 300 women were interviewed who initiated oral contraceptive pill use between December 1995 and April 1996. Participants were interviewed 3–6 months later to investigate the role intimate partner violence played in covert pill use and pill discontinuation. Special study procedures for asking women questions about violence were employed. Nineteen per cent of the women interviewed were using the pill covertly. The odds of covert pill use were four times higher in El Alto and La Paz than in Santa Cruz. Women who used the pill covertly were more likely to have experienced method-related partner violence (OR=21.27) than women whose partners knew of their pill use. One-third of the women had discontinued pill use at the time of the interview. In the final multivariate analysis, having experienced side-effects (OR=2.37) was a significant predictor of pill discontinuation and method-related partner violence was marginally predictive (OR=1.91; 95% CI 1.0–3.66). While efforts are ongoing to incorporate men into family planning programmes, some male partners oppose, and in some situations violently oppose, contraceptive use. The needs of women with these types of partners must not be overlooked.

There is a strong theoretical and empirical relationship between educational attainment and fertility behaviour. However, a fundamental issue that has largely been neglected is the change in this relationship across cohorts resulting from differential improvement in educational opportunities for women over time and how it relates to fertility transition. Utilizing the 1998 DHS data from Kenya this study examines the differential effect of educational attainment on women’s use of modern contraception and desire for cessation of childbearing across generations. The findings indicate that even after controlling for husband’s education and other relevant factors, a woman’s advanced education is positively associated with use of modern contraception. However, support for a similar hypothesis on a woman’s desire for family limitation was only found among the youngest cohort of women. The results suggest that for Kenya’s incipient fertility transition to be sustained the government needs to continue efforts to improve female education and support access to family planning among younger women.

The aim of this study was to determine the consistency of spouses’ declarations about contraceptive use and child desire in Turkey. Husbands eligible for the study were currently married to eligible women, i.e. those who generally lived in the same household or who stayed in the household the night before the interview. Husband questionnaires were completed by 1971 men. It was found that 88·9% of the couples had not talked about family planning with each other in the last two months. The percentage of answers on current contraceptive use for all methods that were consistent for husbands and wives was 70·2%. The consistency among partners who stated they would like to have children in the future was found to be 94·8%, and that among partners who were planning to use a contraceptive method was found to be 88·3%.

Malnutrition among children is prevalent in almost all the states in India. This study assesses the extent and causes of malnutrition in two eastern Indian states with similar climates, namely West Bengal and Assam, using data from the National Family Health Survey 1998–99 (NFHS-2). The three indices of malnutrition taken for analysis are weight-for-height (WHZ), height-for-age (HAZ) and weight-for-age (WAZ). These are assumed to depend on birth order, preceding birth interval, parent’s educational status, working status of the mother, mother’s age at delivery of the children, source of drinking water, toilet facilities and standard of living of the household. Logistic regression was carried out separately for each of the three indices on the explanatory variables for both the states. It was found that not all variables are equally important in determining whether a baby is underweight, or suffering from acute or chronic malnutrition. Also, the importance of variables is not the same in the two states. It was observed that the coefficients associated with the variables in determining weight-for-height are not significant compared with those for weight-for-age and height-for-age.

This note considers two hypotheses on the causes of homosexuality and paedophilia in men, viz. the hypotheses of maternal immunity and of postnatal learning. According to the maternal immune hypothesis, there is progressive immunization of some mothers to male-specific antigens by each succeeding male fetus, and there are concomitantly increasing effects of anti-male antibodies on the sexual differentiation of the brain in each succeeding male fetus. An attempt is made to assess the status of this hypothesis within immunology. Knowledge of the properties of anti-male antibodies is meagre and there has been little direct experimentation on them, let alone on their effects on the developing male fetal brain. Moreover until the relevant antigens are identified, it will not be possible to test mothers of male homosexuals or paedophiles for the presence of such antibodies. Yet until this experimentation has been done, it would seem premature to regard the hypothesis as more than a very provisional explanatory tool. The evidence in relation to the postnatal learning hypothesis is quite different. There is an abundance of data suggesting that male homosexuals and paedophiles report having experienced more sexual abuse (however defined) in childhood (CSA) than do heterosexual controls. The question revolves round the interpretation of these data. Many (though not all) of these studies are correlational and thus subject to the usual qualifications concerning such data. However, there are grounds for supposing that some of the reports are veridical, and there is support from a longitudinal study reporting a small but significant increase in paedophilia in adulthood following CSA. To summarize: most boys who experience CSA do not later develop into homosexuals or paedophiles. However, the available evidence suggests that a few do so as a result of the abuse.

Female- and male-headed households were compared using data from a Demographic and Health Survey conducted in Tanzania in 1996. Chi-squared tests showed that sex of head of household was highly significantly associated with: residence, household size and composition, radio ownership, having enough food to eat, and age and marital status of head of household. An analysis by the logit regression model showed that female-headed households were more likely than male-headed households to be in rural areas, be small, have fewer men, not have radios and not have enough food to eat. The majority of female heads of households were unmarried and older than male heads of households. The implication is that female-headed households are poorer than male-headed households.

This paper traces the development of policies dealing with HIV/AIDS in Botswana from their beginning in the late 1980s to the current programme to provide population-wide anti-retroviral therapy (ARV). Using a variety of source material, including long-term ethnographic research, it seeks to account for the failure of Western-inspired approaches in dealing with the pandemic. It does this by looking at the cultural and institutional features that have created resistance to the message and inhibited effective implementation. The negative response to the first educational campaign stressing condom use is described and contextualized in terms of Tswana ideas of morality and illness. Nor, as was initially expected, did the introduction of free ARV therapy operate to break the silence and stigma that had developed around the disease. Take-up was very slow, and did not operate to encourage widespread testing. In 2003, key policymakers in Botswana began to argue for a break with the AIDS ‘exceptionalism’ position, with its emphasis on voluntarism, confidentiality and the human rights of patients. This resulted in routine testing being introduced in 2004. This links to a major argument running through the paper which is that the failure of policy cannot be attributed solely to the nature of local populations. Western cultural assumptions about ‘good practice’ also require critical examination.

The aim of this research was to explore people’s knowledge, attitude, behaviour and practice towards HIV/AIDS and sexual activity in rural Kenya, where HIV is widespread. The study community was located in south-eastern Kenya, 50 km north of Mombassa, and had an estimated population of 1500. Subjects aged between 16 and 49 were recruited using a stratified cluster-sampling method and they completed self-administered questionnaires.Almost all respondents knew the word ‘HIV’. Around 50% knew of a person living with HIV. About 80% gave ‘death’ or ‘fear’ as words representing their image of AIDS. With regard to sexual activity, the distribution of answers to the question ‘how many partners have you ever had in your life’ was bimodal in males but had only one peak in females, indicating that some men have a large number of sexual partners in their lifetime. First sexual intercourse was at around 12–13 years for both sexes, but female teenagers were more sexually experienced than their male counterparts.

The age at menarche, body height and weight of the daughters of farmers, farmer–workers and landless villagers in a rural region of Poland were studied. In the period 1967–1977, a time of economic development, a decrease in age at menarche (by 0.74 years) and a secular trend in body height (by 2.4 cm/decade) was observed. In 1977–1987, a period of acute economic crisis, age at menarche increased by 0.16 years and the secular trend in body height was only 1.1 cm/decade. In 1987–2001, age at menarche decreased and body height increased by 0.28 years and 2.9 cm respectively. The percentage of families owning a car, freezer and video increased during this period. These last results are indicative of an improvement in living conditions, but the villagers regard themselves as losers as a result of the political transformation (1989) in Poland.

This study focuses on determining the number of children considered ideal by Pakistani husbands and identifying the factors associated with this, with a special emphasis on family type. A cross-sectional survey was conducted among married males residing in four areas of Khairpur district. An equal number of study participants were selected systematically from each field site to achieve the required sample size of 500. Interviews were conducted by trained fieldworkers using a structured questionnaire to obtain information on background socioeconomic characteristics, family structure and reproductive health knowledge and practices, in particular family planning. Multivariate logistic regression analyses were used to assess the hypothesis that family type has an independent association with husbands’ idealization of a larger number of children. The mean ideal number of children perceived by husbands was four. Living in an extended family (AOR=1·81; 95%CI: 1·11, 3·35) and being illiterate (AOR=2·13, 95%CI; 1·33, 3·42) are significantly associated with idealization of a larger number of children by the husband, while adjusting for socioeconomic status, family structure and family planning information. Understanding the dynamics of family type and its effects on husbands’ opinions regarding ideal number of children can help strengthen population control efforts in Pakistan.

Fertility awareness-based methods of family planning help women to identify the days of the cycle they should avoid unprotected intercourse to prevent pregnancy. Therefore using fertility awareness-based methods influences the timing of sexual activity, which may affect the nature of the sexual relationship. Data are used from the clinical trials of two fertility awareness-based methods – the Standard Days Method and the TwoDay Method – to determine the frequency and timing of intercourse during the cycle, and the determinants of coital frequency. The mean coital frequency of study participants was similar to that reported by users of other methods. Results suggest that coital frequency increases with consecutive cycles of method use. At the same time the frequency of intercourse during the identified fertile days and during menses decreases. This evidence implies a behavioural change as couples get more experience using their method and communicating about the fertile days. Coital frequency was also influenced by the method used and by the study sites. Potential differences between the methods and sites that may contribute to this effect are discussed.
