RÉSUMÉ
Background. The level of unintended pregnancies among teenage girls in South Africa (SA) has remained a public health concern. However, studies and interventions generally do not consider young men's involvement in teenage pregnancies. Objective. To investigate the sociodemographic and sexual behaviour characteristics of young men who have impregnated at least one teenage girl. Methods. The study used data from the Centre for Justice and Crime Prevention (2009), which included responses from young men (aged 12 - 22 years) across all SA provinces. Univariate and bivariate analyses and binary logistic regression were performed. Results. The results showed that 93.2% of the sample had â¥2 lifetime sexual partners, 22.4% rarely used condoms and 11.5% had never used condoms. Teenage pregnancy incidence was â¥35% in all provinces except Gauteng and the Western Cape. The likelihood of being involved in a teenage pregnancy was higher among respondents who reported having â¥2 lifetime sexual partners (odds ratio (OR) 2.510; 95% confidence interval (CI) 0.43 - 14.77). Respondents with a higher education were less likely to be involved in a teenage pregnancy (OR 0.819; 95% CI 0.36 - 1.84) than those with a lower education (OR 1.219; 95% CI 0.59 - 2.50). Conclusion. Engaging in multiple sexual partnerships could increase the vulnerability of young people to sexually transmitted infections or teenage pregnancies. Initiatives to create awareness among SA youth regarding the consequences of sexual behaviour are recommended, with a specific focus on addressing young men's involvement in teenage pregnancy

Background. In sub-Saharan Africa, substance use among adolescents has continued to be a major public health concern, albeit poorly documented across many settings. Objective. To estimate the prevalence of substance use among adolescents in sub-Saharan Africa. Methods. We searched Pubmed, EMBASE, AJOL and Google Scholar for population-based studies on adolescents (age 10 - 19 years) and reporting on the prevalence of substance use across sub-Saharan Africa. Search dates were from January 2000 to December 2016. A random effects meta-analysis was conducted with pooled prevalence rates (and 95% confidence interval (95% CI)) of estimated substance abuse among adolescents in sub-Saharan Africa. Results. Twenty-seven studies across sub-Saharan Africa including 143 201 adolescents (mean age 15.6 years) were selected. The overall prevalence of 'any substance use' in sub-Saharan Africa was 41.6%, with the highest rate in Central Africa at 55.5%. The use of caffeine-containing products (including coffee or kola nut) was most predominant at 41.2% (95% CI 24.3 - 58.1) but limited to West Africa. These were followed by alcohol at 32.8% (95% CI 26.0 - 39.5), tobacco products 23.5% (95% CI 17.7 - 29.3), khat 22.0% (95% CI 12.5 - 31.5) and cannabis 15.9% (95% CI 12.2 - 19.1). Other abused substances included depressants at 11.3% (95% CI 6.5 - 16.1), amphetamines 9.4% (95% CI 6.0 - 12.9), heroin 4.0% (95% CI 3.5 - 4.5) and cocaine 3.9% (95% CI 1.4 - 6.5). Conclusion. Our study reflects a high use of psychoactive substances and drugs among adolescents in sub-Saharan Africa. It is important that interventions and rehabilitation programmes are comprehensive and targeted at adolescents and parents in these settings
