Gendered conflict in the human family.

Sexual conflict is a thriving area of animal behaviour research. Yet parallel research in the evolutionary human sciences remains underdeveloped and has become mired by controversy. In this special collection, we aim to invigorate the study of fitness-relevant conflicts between women and men, advocating for three synergistic research priorities. First, we argue that a commitment to diversity is required to innovate the field, achieve ethical research practice, and foster fruitful dialogue with neighbouring social sciences. Accordingly, we have prioritised issues of diversity as editors, aiming to stimulate new connections and perspectives. Second, we call for greater recognition that human sex/gender roles and accompanying conflict behaviours are both subject to natural selection and culturally determined. This motivates our shift in terminology from sexual to gendered conflict when addressing human behaviour, countering stubborn tendencies to essentialise differences between women and men and directing attention to the role of cultural practices, normative sanctions and social learning in structuring conflict battlegrounds. Finally, we draw attention to contemporary policy concerns, including the wellbeing consequences of marriage practices and the gendered implications of market integration. Focus on these themes, combined with attendance to the dangers of ethnocentrism, promises to inform culturally sensitive interventions promoting gender equality worldwide.

Resilience to depression: the role of benevolent childhood experiences in a South African sample.

Background: Studies elsewhere show that benevolent childhood experiences (BCEs) have protective mental health value. However, this protective value has never been investigated in an African context. Given the need to better understand what might support mental health resilience among African young people, this study explores the relationship between BCEs and depressive symptoms among a South African sample of young adults living in a community dependent on the economically volatile oil and gas industry. Methods: A sample of young adults in an oil and gas community in South Africa (N = 313, mean age 20.3 years, SD = 1.83, range from 18 to 26; majority Black African) completed self-report questionnaires to assess BCEs and depressive symptoms (Beck Depression Inventory-II). The analysis controlled for socio-demographics and experience of family adversity. Multinomial logistic regressions were used to examine the association of BCEs with depressive symptoms using STATA 17. Results: The majority (86.4% of the sample) reported all 10 BCEs. Of the 10 BCEs, having at least one good friend was the most reported (94%) compared to 75% of the sample reporting having a predictable home routine, such as regular meals and a regular bedtime. The unadjusted multinomial logistic regression analysis indicated that having at least one good friend, comforting beliefs, and being comfortable with self were associated with lower odds of moderate depression. The adjusted results showed no association between BCEs and the depression of young adults in this sample. Conclusion: In this South African sample, our results do not show protective associations between BCEs and depression. This could be as a result of the homogeneity in our sample. It is also possible that the BCEs explored could not counteract the effect of chronic risk factors in the lives of the young people in this study context. Further research is needed to understand this complexity.

Community structure and timing of sexual activity among adolescent girls in Nigeria.

Studies have linked the timing of sexual debut to unplanned pregnancies and sexually transmissible infections, including HIV. Current understandings of sexual debut among Nigerian adolescents focused on the roles of individual and familial characteristics. We leveraged the 2018 Nigeria Demographic and Health Survey data to examine how community features like affluence, ethnic diversity, and women empowerment may be associated with the timing of sexual debut among adolescent girls. The sample comprised 7449 adolescent girls who were usual residents in 6,505 households and 1,352 clusters or communities. Statistical associations between community characteristics and the onset of sexual debut were assessed using a two-level mixed-effects parametric survival model with Weibull distribution. We found that community affluence [aHR:0.43, 95%CI: 0.30-0.62] and community ethnic diversity [aHR: 0.63, 95%CI: 0.42-0.94] are associated with a lower hazard of sexual debut among adolescent girls. We also observed that women that married within the observation period had an earlier sexual initiation than those who were unmarried. The results disaggregated by marital status further shows that higher community level of women's employment [aHR: 2.45, 95%CI: 1.38-4.38] and women's education [aHR:1.85, 95%CI: 1.03-3.33] were associated with a higher hazard of sexual debut among unmarried adolescent girls but not married adolescent girls. Higher community affluence [aHR:0.40, 95%CI: 0.27-0.60] was also associated with a lower hazard of sexual debut among unmarried adolescent girls but not married adolescent girls. Our results illuminate the associated factors of the timing of sexual debut among adolescent girls that moves beyond individual characteristics to community characteristics.

Decade of research into the acceptability of interventions aimed at improving adolescent and youth health and social outcomes in Africa: a systematic review and evidence map.

OBJECTIVE: Interventions aimed at improving adolescent health and social outcomes are more likely to be successful if the young people they target find them acceptable. However, no standard definitions or indicators exist to assess acceptability. Acceptability research with adolescents in low-and-middle-income countries (LMICs) is still limited and no known reviews systhesise the evidence from Africa. This paper maps and qualitatively synthesises the scope, characteristics and findings of these studies, including definitions of acceptability, methods used, the type and objectives of interventions assessed, and overall findings on adolescent acceptability. DESIGN: We conducted a systematic review of peer-reviewed studies assessing intervention acceptability with young adults (aged 10-24) in Africa, published between January 2010 and June 2020. DATA SOURCES: Web of Science, Medline, PsycINFO, SociIndex, CINAHL, Africa-wide, Academic Search Complete and PubMed were searched through July 2020. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Papers were selected based on the following inclusion criteria: if they (1) reported primary research assessing acceptability (based on the authors' definition of the study or findings) of one or more intervention(s) with adolescents and young adults 10-24; (2) assessed acceptability of intervention(s) aimed at positively influencing one or more development outcome(s), as defined by sustainable development goal (SDG) indicators; (3) reported on research conducted in Africa; (4) were in the English Language; (5) were peer-reviewed and and (6) were published between 1 January 2010 and 30 June 2020. DATA EXTRACTION AND SYNTHESIS: Abstracts were reviewed independently by the two first authors to determine relevance. Full text of potentially eligible studies were retrieved and independently examined by the same two authors; areas of disagreement or lack of clarity were resolved through discussion by the two authors and-where necessary-the assessment of a third author. RESULTS: 55 studies were considered eligible for inclusion in the review. Most studies were conducted in Southern Africa, of which 32 jointly in South Africa and Uganda. The majority of interventions assessed for acceptability could be classified as HIV or HPV vaccine interventions (10), E-health (10), HIV testing interventions (8), support group interventions (7) and contraceptive interventions (6). The objectives of most interventions were linked to SDG3, specifically to HIV and sexual and reproductive health. Acceptability was overall high among these published studies. 22 studies provided reasons for acceptability or lack thereof, some specific to particular types of interventions and others common across intervention types. CONCLUSIONS: Our review exposes considerable scope for future acceptability research and review work. This should include extending acceptability research beyond the health (and particularly HIV) sector and to regions in Africa where this type of research is still scarce; including adolescents earlier, and potentially throughout the intervention process; further conceptualising the construct of acceptability among adolescents and beyond; and examining the relationship between acceptability and uptake.

Migration and interbirth transition rate using Benin Demographic and Health Survey data: Does episode-splitting matter?

BACKGROUND: The relationship between migration and fertility has vexed demographers for years. One issue missing in the literature is the lack of careful temporal consideration of when women migrate and specifically, the extent to which they do either before or after live births. OBJECTIVE: Here, we opt for a more appropriate methodological approach to help remedy the complexity of the temporal aspect of migration and childbirth processes: regression models using the episode-splitting method. METHODS: This paper applies a rarely used methodological approach (episode-splitting) in the literature of migration-fertility relationship to investigate how internal in-migration is associated with inter-birth intervals among women in Cotonou, the largest city of Benin. Data comes from the 2017-2018 Benin Demographic and Health Survey (DHS) of women aged 15-49. Estimates from exponential regression models with episode-splitting were compared to estimates from exponential regression models without episode-splitting approach. Sensitivity analysis was also conducted to determine the robustness of the comparison between the two methods. Akaike Information Criteria (AIC) and Bayesian Information Criteria (BIC) were used to identify the method that provides models with best fit. RESULTS: The results from (standard) exponential regression models without episode-splitting show that there is no significant association between migration and interbirth transition rate. However, significant associations between migration and interbirth transition rate emerge after applying the episode splitting method. The hazard ratios (HR) of the transition to the next live birth are higher among migrant women than among nonmigrant women. This trend is persistent even after 10 years spent in Cotonou by migrant women. CONCLUSION: Exponential regression models with episode-splitting were of better fit than exponential regression models without episode-splitting. Sensitivity analysis conducted seems to confirm that models with episode-splitting produce estimates that are accurate, reliable and superior to models without episode-splitting. The results suggest a long-run process adaptation of migrants to lower fertility behaviours in Cotonou and are therefore consistent with the socialization hypothesis.

Reproductive awareness and recognition of unintended pregnancy: young women, key informants and health care providers perspectives in South Africa.

BACKGROUND: South Africa has a liberal abortion law, yet denial of care is not uncommon, usually due to a woman being beyond the legal gestational age limit for abortion care at that facility. For women successfully obtaining care, time from last menstrual period to confirmation of pregnancy is significantly longer among those having an abortion later in the second trimester compared to earlier gestations. This study explores women's experiences with recognition and confirmation of unintended pregnancy, their understanding of fertile periods within the menstrual cycle as well as healthcare providers' and policy makers' ideas for public sector strategies to facilitate prompt confirmation of pregnancy. METHODS: We recruited participants from July through September 2017, at an urban non-governmental organization (NGO) sexual and reproductive health (SRH) facility and two public sector hospitals, all providing abortion care into the second trimester. We conducted in-depth interviews and group discussions with 40 women to elicit information regarding pregnancy recognition and confirmation as well as fertility awareness. In addition, 5 providers at these same facilities and 2 provincial policy makers were interviewed. Data were analysed using thematic analysis. RESULTS: Uncertainties regarding pregnancy signs and symptoms greatly impacted on recognition of pregnancy status. Women often mentioned that others, including family, friends, partners or colleagues noticed pregnancy signs and prompted them to take action. Several women were unaware of the fertility window and earliest timing for accurate pregnancy testing. Health care providers and policy makers called for strategies to raise awareness regarding risk and signs of pregnancy and for pregnancy tests to be made more readily accessible. CONCLUSION: Early recognition of unintended pregnancy in this setting is frustrated by poor understanding and awareness of fertility and pregnancy signs and symptoms, compounded by a distrust of commercially available pregnancy tests. Improving community awareness around risk and early signs of pregnancy and having free tests readily available may help women confirm their pregnancy status promptly.

South Africa has one of the world's most progressive legal frameworks for abortion, yet it's not uncommon for women to struggle to access safe abortion services. A key reason for this is late recognition of an unplanned pregnancy. This study explored the lived experiences leading up to pregnancy confirmation among women securing abortion care beyond 9 weeks gestational age, the legal limit for home use of medication for abortion. It fills a gap by also including providers' and policy makers' perspectives on ways to strengthen women's prompt recognition of pregnancy. Using group discussions and in-depth interviews we elicited information from 40 women and 7 providers and policy makers in two health subdistricts in the Western Cape Province, South Africa. Our findings highlight the process of pregnancy recognition and confirmation and women's knowledge of fertility, the menstrual cycle and when to test for pregnancy. Our results suggest that factors influencing women's recognition of pregnancy are at the individual and at community level. Health care providers and policy makers suggested the use of community-based services to raise awareness around early pregnancy testing, and to expand easy access to self-testing outside the formal clinic setting as a mechanism to overcome clinic-based barriers.

The role of mentoring in research ecosystems in Sub-Saharan Africa: Some experiences through the CARTA opportunity.

Mentoring is important for improving capacity development in population and public health research in sub-Saharan Africa. A variety of experiences have been documented since Consortium for Advanced Research Training in Africa (CARTA) admitted the first cohort in 2011. However, the experience of mentoring opportunities in CARTA has not been studied. Our study focused on the perceptions, experiences and challenges of mentoring among CARTA fellows. We adopted a descriptive design based on data collected from the fellows using an online semi-structured questionnaire. Out of 143 fellows in the programme, a total of 52 fellows from seven cohorts completed the questionnaire. Fifty-three percent of the respondents were females, more than half belonged to the health sciences while 35% were in the social sciences. Fellows received mentoring from CARTA graduates and experienced researchers in the CARTA network, but they also engaged in peer-mentoring with one another. Teaching, publishing, conference attendance and grant application were considered particularly important in mentoring, but mentors and mentees highlighted personal and social issues such as networking, work-family life balance, and managing stress and time, as challenges. There is a need for more formalised but flexible mentorship initiative in the CARTA fellowship to facilitate enduring relationships for career development.

Provision of immediate postpartum contraception to women living with HIV in the Eastern Cape, South Africa; a cross-sectional analysis.

BACKGROUND: Universal access to contraception is an important strategy adopted by the South African government to reduce the high rate of unintended pregnancies, especially in women living with HIV. In this article, we describe the choices of contraception and also, examine the influencing factors of the choices of contraception in the immediate postpartum period in parturient women with HIV in the Eastern Cape, South Africa. METHODS: In this prospective cross-sectional study, 1617 parturient women with HIV completed a survey on the choice of contraception received in the immediate postpartum period (within 72 h) across three large maternity services in the Eastern Cape between September 2015 to May 2016. Additional information was extracted from their medical records. Choices of contraception were categorised as; short-acting (injectables), long-acting reversible (intrauterine device and implants) and permanent contraception (tubal ligation). Adjusted and unadjusted logistic regression models were employed to determine the influencing factors of the choices of contraception received by the cohort. RESULTS: Participants were predominantly single (69.1%), unemployed (75.1%), had a grade 7-12 level of education (88.4%) and were HIV positive before their index pregnancy (81.3%). The prevalence of immediate postpartum contraception was high (n = 1507; 93.2%) with Injectables being the preferred choice in the majority of the participants (n = 1218; 75.3%). After controlling for all relevant covariates, single marital status was associated with a higher likelihood of immediate postpartum contraceptive initiation (AOR; 1.82 95% CI 1.10-3.03). Overall, women were more likely to initiate a long-acting reversible and irreversible methods when older than 35 years and having had more than two children. CONCLUSIONS: We found a high prevalence of immediate postpartum contraception with a preference for Injectables in the study setting. Long-term monitoring of this cohort will elucidate on contraceptive discontinuation and risk of unintended pregnancies in the region. Ensuring universal access to contraceptives is an important strategy to reduce the rate of unintended pregnancies at the population level. This strategy was adopted by the South African government with a vision of stemming the tide of unintended pregnancies among women living with HIV. In this study, the choices of contraception adopted by women living with HIV following the delivery of their babies were explored. In addition, the study highlights the factors that predict these choices. Participants were asked the choice of contraception they had received prior to being discharged from the maternity centres where they had delivered their babies. The various types of contraception were then categorised by their duration of action. Three distinct groups emerged; short-acting injectables, long acting reversible contraceptives and permanent methods. Of the 1617 women included in the study, 1117 were single and 1314 knew their HIV status prior to the onset of the index pregnancy. Almost all the women (1507 out of 1617) received one form of contraception before leaving the hospital. Many women (1218 out of 1617) chose injectable contraception (short-acting contraception) over the other types of contraception. Women who were older than 34 years and who had three or more children were more likely to choose a long-acting reversible contraceptive and permanent method over the short-acting contraception or nothing. In conclusion, given the short duration of action of the predominant method adopted by these women, a long-term follow up of the study participants will provide more information on the continued use of contraception and risk for unintended pregnancies.

The effect of family and neighbourhood social capital on youth mental health in South Africa.

INTRODUCTION: Despite the prevalence of mental illness among young adults in South Africa, few studies have examined its correlation with social capital using nationally representative data. Sources of social capital are different for youth, which is why understanding the correlation between family and neighbourhood social capital and mental health outcomes is important for designing optimal interventions. The objective of this study was to examine the relationship between social capital and youth mental health. We also sought to understand whether family social capital was more protective for the mental health of youth compared to neighbourhood social capital. METHODS: Using the National Income Dynamics Survey data for South Africa, we examine these associations among 2307 youth aged 15-24 across the four waves. Multilevel logistic regression was used to examine these associations. RESULTS: Our findings emphasize the substantial burden of mental illness among youth in South Africa (26% in wave 4). Although results for parental presence were not significant, family social capital measured by household income significantly decreased the odds of incident depression only for those belonging to the third quintile (aOR 0.74, 95% CI 0.54-1.01). High perception of crime in the neighbourhood was associated with significantly higher odds of incident depression (aOR 1.33, 95% CI 1.06-1.67). CONCLUSIONS: Our results confirm the independent effect of neighbourhood characteristics on youth mental health and did not support family social capital as being protective for developing depression. This implies that youth program planners must focus on community context in improving youth developmental outcomes such as mental health.

Recreational drug use among Nigerian university students: Prevalence, correlates and frequency of use.

BACKGROUND: Given the paucity of data on recreational drug use and the recent media attention on the abuse of drugs such as codeine cough syrups and tramadol, in Nigeria, our study examined the prevalence and frequency of recreational drug use among young adults from two Nigerian universities. We drew from the Socio-ecological Model to examine the influence of factors at the individual and family level on recreational drug use among adolescents and young adults. METHODS: This cross-sectional study was conducted between February and March 2018 among a final sample of 784 male and female university students selected using stratified random sampling. Binary logistic regression was used to identify significant predictors of ever use and current use of drugs. RESULTS: Our analyses showed that 24.5% of students had ever used drugs for recreational purposes, and 17.5% are current users. The median drug use frequency over the past month was six days among current users (n = 137). In the multivariable analyses, living in the same household as one's mother (AOR 0.28 95% CI 0.16-0.49), adequate family support (AOR 0.48 95% CI 0.26-0.89) and frequent attendance of religious fellowships (AOR 0.13 95% CI 0.07-0.25) were significantly associated with a lower likelihood of recreational drug use. However, male sex (AOR 1.52 95% CI 1.05-2.21) was associated with higher odds of recreational drug use. CONCLUSION: The family should be considered as an important unit to sensitize young people on the harmful effects of drug use. It is also vital that religious leaders speak against drug use in their various fellowships. There is a need to address recreational drug use on Nigerian campuses by educating students about its adverse impacts.

Patterns and determinants of short and long birth intervals among women in selected sub-Saharan African countries.

Optimal birth spacing (defined as a birth spacing of 24-59 months) is incontrovertibly linked to better health outcomes for both mothers and babies. Using the most recent available Demographic and Health Survey data, we examined the patterns and determinants of short and long birth intervals among women in selected sub-Saharan African (SSA) countries.Reproductive health and sociodemographic data of 98,934 women from 8 SSA countries were analyzed. Unadjusted and adjusted multinomial logistic regression models were used to examine the net relationship between all the independent variables and short and long birth intervals.Overall, the majority of women in all the countries optimally spaced births. However, a significant proportion of women had short birth intervals in Chad (30.2%) and the Democratic Republic of Congo (Congo DRC) (27.1%). Long birth spacing was more common in Eastern and Southern African countries, with Zimbabwe having the highest rate of long term birth interval (27.0%). Women who were aged 35 years and above in Uganda (RRR = 0.72, CI = 0.60-0.87), Tanzania (RRR = 0.62, CI = 0.49-0.77), Zimbabwe (RRR = 0.52, CI = 0.31-0.85), Nigeria (RRR = 0.82, CI = 0.72-0.94) and Togo (RRR = 0.67, CI = 0.46-0.96) had significantly lower odds of having short birth intervals compared to women aged 15-24 years. Older women (above 34 years) had increased odds for long birth intervals in all countries studied (Chad (RRR = 1.44, CI = 1.18-1.76), Congo DRC (RRR = 1.73, CI = 1.33-2.15), Malawi (RRR = 1.54, CI = 1.23-1.94) Zimbabwe (RRR = 1.95, CI = 1.26-3.02), Nigeria (RRR = 1.85 CI = 1.56-2.20), Togo (RRR = 2.12, CI = 1.46-3.07), Uganda (RRR = 1.48, CI = 1.15-1.91), Tanzania RRR = 2.12, CI = 1.53-2.93).The analysis suggested that the determinants of long and birth intervals differ and varies from country to country. The pattern of birth spacing found in this study appears to mirror the contraceptive use and fertility rate in the selected SSA countries. Birth intervals intervention addressing short birth intervals should target younger women in SSA, especially in Chad and Congo DRC, while intervention for long birth spacing should prioritize older, educated and wealthy women.

Trends, patterns and determinants of long-acting reversible methods of contraception among women in sub-Saharan Africa.

BACKGROUND: Method-specific contraceptive prevalence varies widely globally, as huge variations exist in the use of different types of contraception, with short-term methods being the most common methods in sub-Saharan Africa (SSA). Evidence is scanty on the trends, patterns and determinants of long-acting reversible contraceptive (LARC) methods in SSA. This study aimed to address this knowledge gap. METHODS: Using a pseudo longitudinal research design and descriptive and inferential statistics, we analysed Demographic and Health Survey data of eight countries selected on the basis of contraceptive prevalence rates across SSA. Multinomial logistic regression modelling was used to tease out the predictors of the uptake of LARC methods in the selected countries. RESULTS: Findings exhibit a steady but slow upward trend in LARC methods across selected countries, as a marginal increase was recorded in LARC uptake over a 10-year period in many of the selected countries. Results established significant predictors of LARC methods uptake, including fertility-related characteristics, age, level of education, work status, wealth index and exposure to mass media. This study underscored the need to address various barriers to the uptake of LARC methods in SSA. It is recommended that governments at different levels undertake to cover the costs of LARC methods in order to increase access and uptake.

Religiosity and sexual abstinence among Nigerian youths: does parent religion matter?

BACKGROUND: Religion plays an important role in youth behaviours, making it a significant factor in the discourse on youth sexuality in sub-Saharan Africa. Several studies have found that religion and religiosity play an important role in the sexual behaviours of young people. However, little research in Nigeria has examined the mechanisms through which religiosity influences youth sexual behaviour and if parents' religion moderates this relationship. Guided by the social control theory, this paper contributes to the existing literature by examining the relationship between religiosity and youth sexual behaviour. METHODS: Data for the study came from 2399 male and female youth aged 16-24 years in four states purposively selected from four regions in Nigeria. Abstinence was the sexual behaviour of interest. Logistic regression was used to examine this relationship. RESULTS: Results showed that 68% of the youth had never had sex. Religiosity was a protective factor for youth sexual behaviour and this positive association was still evident even after controlling for other covariates. Youth who were highly religious (OR - 1.81, CI- 1.13-2.88) had significantly higher odds of abstaining compared to their counterparts who were not religious. CONCLUSION: Religiosity is a protective factor for sexual abstinence among youth in Nigeria. Policy makers can work around using religious institutions for behavioural change among youth in Nigeria.

Transactional sex among Nigerian university students: The role of family structure and family support.

BACKGROUND: The reasons for the persistence of risky sexual behaviours among adolescents and young adults in sub-Saharan Africa despite the increasing knowledge about the associated risks continue to attract scholarly debates. Drawing from a cross-sectional study conducted among male and female Nigerian university students, we examined the relationship between family structure, family support and transactional sex. METHODS: A pre-validated questionnaire was administered to 800 male and female students selected using stratified sampling; however, we performed the analysis on 630 participants who had ever engaged in sex. Transactional sex was operationalised as self-reporting of giving or receiving money, gifts or favour in exchange for sex. We fitted a list-wise logistic regression model to examine the relationship between family structure, family support and transactional sex while controlling for essential covariates. RESULTS: Of the 630 participants included in the analysis, 17.9% had given and 23.8% had received money, gift or favour in exchange for sex. Our bivariate analysis shows that individuals from polygamous families had higher odds of reporting that they have ever given (AOR: 1.89; CI: 1.05-3.39) or received (AOR: 1.85; CI: 1.85-3.19) money, gift or favour in exchange for sex; however, the relationship was not statistically significant after controlling for relevant covariates. After controlling for essential covariates, the odds of giving or receiving money, gift or favour in exchange for sex was 56% lower in individuals who received adequate family support compared to those who received no or insufficient family support. CONCLUSION: In conclusion, this paper lends support to the assertion that family structure and family support are protective factors against transactional sex among adolescents and young adults. Future surveys need to include a larger sample in order to explore the effect of single-parent and polygamous family on transactional sex in Nigeria where family formation is changing rapidly.

REGIONAL DIFFERENCES IN POSITIVE SEXUAL BEHAVIOUR AMONG YOUTH IN SUB-SAHARAN AFRICA.

The question of youth sexual behaviour has been widely debated, with researchers such as Berhan and Berhan (2015) arguing that young adults aged 15-24 are more likely to engage in risky behaviours. However, research has not adequately addressed the issue of positive sexual behaviours, in particular among young people in sub-Saharan Africa. Adapting the compensatory model of risk and resiliency theory, this study examined the determinants of positive sexual behaviours among youth in sub-Saharan Africa. Using recent data from Demographic and Health Surveys of sixteen countries representative of each African region (East, West, Southern and Central), it was hypothesized that positive sexual behaviours of youth (condom use at last sex and single sexual partnership) would be most strengthened by protective factors at the individual and family levels, and that these behaviours would differ by region due to regional variation in socio-cultural practices. Delayed age at sexual debut (first sex after the age of 15) was found to be the strongest protective factor for positive sexual behaviours among males and females in sub-Saharan Africa. Certain socioeconomic variables were found to be positively associated with positive sexual behaviours and the associations differed by gender.

The protective role of family structure for adolescent development in sub-Saharan Africa.

Several studies have focused on the risk factors associated with adolescent developmental outcomes, but the literature on the role of protective factors at the family and community level for positive adolescent development is scarce, especially in sub-Saharan Africa (SSA). We hypothesize that ensuring a supportive environment for adolescents may result in delayed sexual debut for adolescents in SSA. The relationship between family structure and positive adolescent sexual behaviour, measured as delay in sexual debut, was examined using the bioecological theory framed by a risk and resilience perspective. We used nationally representative data on female and male adolescents (aged 15-17 years) from 12 countries in SSA. We modelled logistic regressions to test for associations between family structure and delayed sexual debut while controlling for other covariates in SSA. The majority (90%) of the young adults delayed sexual debut, and this delay varied by family structure. After controlling for other covariates, adolescents living with neither parent had lower odds of delaying sexual debut although results were only significant for males. Interaction terms with community socio-economic status showed an interaction between community education and males living with neither parent. Future studies must investigate the gender differentials in the relationship between family structure and delayed sexual debut among adolescents in SSA.

Adult mortality in sub-Saharan Africa using 2001-2009 census data: does estimation method matter?

Adult mortality is an important development and public health issue that continues to attract the attention of demographers and public health researchers. Controversies exist about the accurate level of adult mortality in sub-Saharan Africa (SSA), due to different data sources and errors in data collection. To address this shortcoming, methods have been developed to accurately estimate levels of adult mortality. Using three different methods (orphanhood, widowhood, and siblinghood) of indirect estimation and the direct siblinghood method of adult mortality, we examined the levels of adult mortality in 10 countries in SSA using 2001-2009 census and survey data. Results from the different methods vary. Estimates from the orphanhood data show that adult mortality rates for males are in decline in South Africa and West African countries, whilst there is an increase in adult mortality in the East African countries, for the period examined. The widowhood estimates were the lowest and reveal a marked increase in female adult mortality rates compared to male. A notable difference was observed in adult mortality estimates derived from the direct and indirect siblinghood methods. The method of estimation, therefore, matters in establishing the level of adult mortality in SSA.

Perceptions of social capital and sexual behaviour among youth in South Africa.

With about one quarter of new human immunodeficiency virus (HIV) infections occuring in young people, there is an on-going debate regarding the role of social capital on youth sexual behaviour. Some studies have suggested that high levels of family and community social capital may act as protective factors that lessen the likelihood of negative consequences; while others have concluded that social capital may be a risk factor for risky sexual behaviour among youth. Using data from the Third National Communications Survey (2012) conducted in South Africa, we examined the relationship between perceptions of social capital and youth sexual behaviour measured by age at first sex and condom use among 3 399 males and females (aged between 16 and 24 years). We assessed community perceptions of social capital with questions that measured trust, social participation, and support. The Cox proportional hazards regression model was used to predict the risk for early sexual debut. Logistic regression was used to predict the odds of condom use. There was no association between perceptions of social capital and youth sexual behaviour. This work reveals that youth sexual behaviour in South Africa may be influenced by socio-economic characteristics, especially at the individual level.

Ethnicity, gender and risky sexual behaviour among Nigeria youth: an alternative explanation.

BACKGROUND: While studies in demography and public health have acknowledged the role of ethnic differences, the influence of ethnicity on youth sexual behaviour in Nigeria has received little or no attention. It is important to know how cultural norms and gender roles, which vary by ethnicity, may promote or prevent risky behaviour. Such information could provide insights into previously undetected sexual behaviour in multi-ethnic situations. METHODS: The Nigeria Demographic and Health Surveys (NDHS) for 2003, 2008 and 2013 were pooled to examine the relationship between ethnicity and youth sexual reproductive health, proxied by age at sexual debut, multiple sexual partners (MSP) and condom use at last sexual activity, among the 6304 females and 1549 males who reported being sexually active in the four weeks preceding the survey. Multivariate analysis using a Cox proportional hazard regression model was used to determine the risk factors for early sexual activity among young people (15-24). Logistic regression was used to predict condom use at last sexual activity and MSP. RESULTS: The median age at first sexual activity was 16 for females and 17 for males. 43% of male youths used condoms in their last sexual activity, compared to only 16% among females and a higher number of males (81%) had multiple sexual partners compared to females (35%). For females, elevated risks of first sex was higher among Hausa/Fulanis aged 15-19 and elevated risk of first sex was higher among Yoruba males. CONCLUSION: This study provides further evidence that in order to promote protective sexual behaviours among youth in Nigeria, social, cultural and gender-specific tactics should be put in place for the prevention of HIV and other STIs.
