Background Existing studies indicate that about one in every six children dies before age five in Nigeria. While evidence suggests that improved access to adequate health care holds great potential for improved child survival, previous studies indicate that there are substantial barriers to accessing health care in Nigeria. There has not been a systematic attempt to examine the effects of barriers to health care on under-five mortality in Nigeria. This study is designed to address this knowledge gap. Data and method Data came from a nationally representative sample of 18,028 women (aged 15–49) who had a total of 28,647 live births within the 5 years preceding the 2008 Nigeria Demographic and Health Survey. The risk of death in children below age five was estimated using Cox proportional hazard models and results are presented as hazards ratios (HR) with 95% confidence intervals (CI). Results Results indicate higher under-five mortality risks for children whose mothers had cultural barriers and children whose mothers had resource-related barriers to health care (HR: 1.44, CI: 1.32–1.57, p<0.001), and those whose mothers had physical barriers (HR: 1.13, CI: 1.04–1.24, p<0.001), relative to children whose mothers reported no barriers. Barriers to health care remained an important predictor of child survival even after adjusting for the effects of possible confounders. Conclusion Findings of this study stressed the need for improved access to adequate health care in Nigeria through the elimination of barriers to access. This would enable the country to achieve a significant reduction in childhood mortality.Background Existing studies indicate that about one in every six children dies before age five in Nigeria.

South Africa has one of the highest HIV/AIDS prevalence rates in the world. It is estimated that 5.38 million South Africans are living with HIV/AIDS. In addition, new infections among adults aged 15+ were reportedly 316 900 in 2011. New infections among children (0–14 years old) was also high in 2011 at 63 600. This paper examines South Africas mortality due to HIV/AIDS among the youth (15–34 years old). This age group is of fundamental importance to the economic and social development of the country. However, the challenges of youth development remain vast and incomparable. One of these challenges is the impact of HIV/AIDS on mortality. Life table techniques are used to estimate among others, sex differentials in death rates for the youth population, probability of dying from HIV/AIDS before the age of 35 and life expectancy should HIV/AIDS be eradicated from the population. The study used data from the National Registry of Deaths, as collated by Statistics South Africa from 2001 to 2009. Results show that youth mortality due to HIV/AIDS has remained consistently higher among older youths than in younger ones. By sex, mortality due to this cause has also remained consistent over the period, with mortality due to HIV/AIDS being higher among females than males. Cause-specific mortality rates and proportional mortality ratios reflect the increased mortality of older youth (especially 30–34 years old) and females within the South African population. Probability of dying from HIV/AIDS shows that over the period, fluctuations in likelihood of mortality have occurred, but for both males and females (of all age groups) the chances of dying from this cause decreased in 2007–2009.

The paper presents the interaction effect of poverty-wealth status and autonomy on modern contraceptive use in Nigeria and Namibia with a view to examining whether poor women with less autonomy are less likely to use modern contraception than other women. A weighted sample of 3,451 currently married women in 2006-07 Namibia Demographic and Health Survey (DHS) and 23,578 in 2008 Nigeria (DHS) are used in the analysis. In Nigeria, the odd of using modern contraception is nearly 15 times higher among rich women with more autonomy than their counterparts who are poor and are less autonomous and 5.5 times higher among Namibian women. The study concluded that contraceptive behaviors of currently married women of Namibia and Nigeria are not independent of the linkage between poverty and autonomy and thus recommended that more concerted efforts be made in addressing poverty and improving the autonomous status of women in sub-Sahara Africa.

ABSTRACT One of the reasons for the perpetuation of female circumcision is that it controls female sexuality. In this study, the authors examined the relationship between female circumcision and the sexual behavior of women in Kenya and Nigeria. Data on women who were aware of circumcision and were circumcised were extracted from the Kenya Demographic and Health Survey of 2008–09 as well as the Nigeria Demographic and Health Survey of 2008. The sample size was 7,344 for Kenya and 16,294 for Nigeria. The outcome variables were age at first intercourse and total lifetime number of sexual partners. The study hypothesis was that women who were circumcised were less likely to have initiated sex early and to have only one sex partner. Cox proportional hazards regression and Poisson regression were used to examine the relations of female circumcision and other selected variables to sexual behavior. No association was observed between female circumcision and the outcomes for sexual behavior of women in Kenya and Nigeria. The argument of sexual chastity is insufficient to sustain the perpetuation of female circumcision.

Place of death remains an issue of growing interest and debate among scholars as an indicator of quality of end-of-life care in developed countries. In sub-Saharan Africa, however, variations in place of death may suggest inequalities in access to and the utilization of health care services that should be addressed by public health interventions. Limited research exists on factors associated with place of death in sub-Saharan Africa. The study examines factors associated with the place of death among Zambian adults aged 15–59 years using the 2010–2012 sample vital registration with verbal autopsy survey (SAVVY) data, descriptive statistics and multivariate logistic regression analysis. Results show that more than half of the adult deaths occurred in a health facility and two-fifths died at home. Higher educational attainment, urban versus rural residence, and being of female gender were significant predictors of the place of death. Improvement in educational attainment and investment in rural health facilities and the health care system as a whole may improve access and utilization of health services among adults.

Abstract Abortion is legal in South Africa, but over half of abortions remain unsafe there. Evidence suggests women who are (Black) African, of lower socioeconomic status, living with HIV, or residents of Gauteng, KwaZulu-Natal, or Limpopo provinces are disproportionately vulnerable to morbidity or mortality from unsafe abortion. Negative attitudes toward abortion have been documented in purposively sampled studies, yet it remains unclear what attitudes exist nationally or whether they differ across sociodemographic groups, with implications for inequities in service accessibility and health. In the current study, we analysed nationally representative data from 2013 to estimate the prevalence of negative abortion attitudes in South Africa and to identify racial, socioeconomic and geographic differences. More respondents felt abortion was ‘always wrong’ in the case of family poverty (75.4%) as compared to foetal anomaly (55%), and over half of respondents felt abortion was ‘always wrong’ in both cases (52.5%). Using binary logistic regression models, we found significantly higher odds of negative abortion attitudes among non-Xhosa African and Coloured respondents (compared to Xhosa respondents), those with primary education or less, and residents of Gauteng and Limpopo (compared to Western Cape). We contextualise and discuss these findings using a human rights-based approach to health.

Background Resolution of public health problems in Africa remains a challenge because of insufficient skilled human resource capacity. The Consortium for Advanced Research Training in Africa (CARTA) was established to enhance capacity in multi-disciplinary health research that will make a positive impact on population health in Africa. Objective The first cohort of the CARTA program describes their perspectives and experiences during the 4 years of fellowship and puts forward suggestions for future progress and direction of research in Africa. Conclusions The model of training as shown by the CARTA program is an effective model of research capacity building in African academic institutions. An expansion of the program is therefore warranted to reach out to more African academics in search of advanced research training.Background Resolution of public health problems in Africa remains a challenge because of insufficient skilled human resource capacity.

Background Crime and violence causes massive disruptions to the health, survival and development of populations. In South Africa, incredibly high rates of crime and violence are noted. The country also has a very large youth population whose health, survival and development are key to economic growth. Among other efforts to encourage healthy youth development and the promotion of social activities such as sports, youth groups, choirs and so forth. This study examines the relationship between perceived community safety and the uptake of social activities among youth in South Africa. Data and methods This paper uses data from the National Youth Lifestyle Survey (2008) with an unweighted sample of 4,391 youth (age12-22 years old). Using chi-square and logistic regression analysis the association between perceived community safety and social activity participation are tested. Findings The results indicate that youth participation in social activities in South Africa is high (55% of males and 45% of females). Among males, the most prominent activity is sports (51.8%), while for females there is high participation in choir and singing groups (55.68%). More than 50% of males perceive their communities as risky while less than half of females feel the same. Male youth are more likely to participate in social activities if they perceive their communities as risky (OR = 1.04). Females (OR = 0.83), youth have a negative view of their future (OR = 0.43) are less likely to participate in social activities. Conclusions There exists an association between youth’s perception of community safety and their participation in social activities. Whether sports and groups are protective or enabling environments for youth from unsafe communities is moot. More in-depth research is needed on why youth participate in these clubs and groups to truly understand the role of social activities in South African societies.

ABSTRACT Theories of youth risk taking range from the realist to the sociocultural. Much of this theorising, particularly in the field of epidemiology, has been strongly influenced by the Health Belief Framework. More recently, attention has shifted to understanding how young people perceive risk and what makes some of them resilient to risk taking. In this article we develop a framework that brings together diverse theoretical perspectives on youth risk taking. We draw on lessons from across the social science disciplines to inform a conceptual framework incorporating the broad context and internal processes of young peoples decisions to take risks. Our Youth Risk Interpretation Framework (Y-RIF) has been developed from insights gained during an ethnographic study conducted in South Africa (Graham, Lauren, 2012. Understanding risk in the everyday identity-work of young people on the East Rand of Johannesburg. Doctoral Thesis. University of Johannesburg, Johannesburg.). We argue that our framework is useful, as it offers new ways of understanding why some young people take risks while others are more cautious. It could be used to inform youth behaviour surveillance research and interventions. However, it will need to be rigorously tested.

Abstract The purpose of this study is to examine the association between extra-curricular activities and risky sexual and illicit drug use behaviours among youth (12–22 years old) in South Africa. The study uses nationally representative data. Descriptive statistics and logistic regression models are used. Results show that a high percentage of youth engage in at least one type of risky sexual behaviour (33.84%) and have used at least one type of illicit substance (7.79%). Sports (about 60%) and youth groups (about 15%) are the most popular forms extra-curricular activities. Further, the odds of risky sexual behaviour are higher for youth who participate in sports (OR = 1.29, p-value < .05) and youth groups (OR = 1.58, p-value < .05). While youth who engage in other, undefined extra-curricular activities (OR = 2.11, p-value < .05) and sports (OR = 1.03, p-value < .05) have higher odds of illicit drug use. There is need to monitor and evaluate local extra-curricular activities to prevent risky behaviours among youth.
