The influence of gender-equitable attitudes on sexual behaviour among unmarried adolescents in rural Tanzania: a longitudinal study
Gender norms that centre men and disadvantage women create gender inequality, which can lead to risky sexual behaviour. This study examined how both community and individual attitudes toward gender norms influenced risky sexual behaviour in adolescents, and whether that influence was different between males and females. We found that higher gender-equitable attitudes were linked to increased odds of HIV testing in the last 12 months, and decreased odds of engaging in a sexual relationship with a much older partner. Individual high gender-equitable attitudes among girls were also linked to higher odds of them using condoms and contraceptives. Gender-equitable attitudes did not seem to influence early sexual debut, engagement in transactional sex, having multiple sexual partners at the same time, or the number of sexual partners a participant had in the last 12 months. Based on these findings, programming designed to increase gender-equitable attitudes might be helpful in increasing HIV testing and condom and contraceptive use, but it needs to involve the entire community, not just individual boys and girls.

Whither ‘Sub-Saharan Africa’ Can We Use the Compass Instead?
Currently, there are few conversations about the term ‘Sub-Saharan Africa (SSA)’ (L.T. 2019) and its continued use (Zeleza 2022; Daley and Murrey, 2022). An end to the use of this problematic term is long overdue, and African voices on this matter should be amplified. This contribution to the literature aims to offer a solid reference point to support discussions about the discontinued use of this virulent term due to its racialist origins and racist undertones (Adébísí 2016; Chachage 2020; Ekwe-Ekwe 2012; Zeleza 2010). Through the voices of several prominent Africans, we explore the term’s invention, its scholarly (dis)advantages, and potential harm in its continued usage.

Exploring multilevel social determinants of depressive symptoms for Tanzanian adolescents: evidence from a cross-sectional study
Background Depression has substantial and enduring impacts for adolescents, particularly those living in poverty. Yet, evidence on its determinants in low-income countries remains scarce. We examined the social determinants of depressive symptoms for Tanzanian adolescents. Methods We used cross-sectional data for 2458 adolescents (aged 14–19), to describe associations with depressive symptoms within and across five domains—demographic, economic, neighbourhood, environmental and social-cultural—using linear mixed models. We estimated depressive symptoms using the 10-item Centre for Epidemiological Studies Depression Scale, which ranges from 0 to 30 and increases with additional symptoms. Results Factors associated with depressive symptoms in the fully adjusted models included experiencing five or more household economic shocks (β=2.40; 95% CI 1.48 to 3.32), experiencing droughts/floods (β=0.76; 95% CI 0.36 to 1.17), being in a relationship (β=1.82; 95% CI 1.30 to 2.33), and having moderate (β=1.26; 95% CI 0.80 to 1.71) or low (β=2.27; 95% CI 1.81 to 2.74) social support. Exclusive schooling was protective compared with being engaged in both school and paid work (β=1.07; 95% CI 0.05 to 2.61) and not engaged in either (β=0.73; 95% CI 0.24 to 1.22). Household size and relationship status were more important factors for girls, while employment status, and extreme precipitation were more important for boys. Conclusion Mental health is associated with determinants from multiple domains. Results suggest that environmental shocks related to climate change contribute to poor mental health in adolescents, highlighting an important area for intervention and research.

Engaging Young Men as Community Health Leaders in an STI and Intimate Partner Violence Prevention Trial in Dar es Salaam, Tanzania
Background This article presents lessons learned from a microfinance and health intervention for young men designed to prevent sexually transmitted infections (STI) and intimate partner violence (IPV) in Dar es Salaam, Tanzania. We describe the different strategies we used to identify and train young men to become change agents within their social networks. Description A cluster-randomized trial with 60 camps was undertaken in the Kinondoni District of Dar es Salaam. A total of 170 members from 30 intervention camps were trained in March 2014 as popular opinion leaders (POLs), whom we call Camp Health Leaders (CHLs). We describe the process of nominating, training, and retaining CHLs. We also describe our monitoring process, which included the collection of weekly diaries assessing topics discussed, number of peers engaged in conversations, reactions of peers, and challenges faced. Lessons Learned POLs within naturally existing social networks can be engaged in STI and IPV prevention initiatives. Continuous efforts in retention, such as holding community advisory board (CAB) meetings, developing prevention slogans and t-shirts, and offering small grants to POL teams for intervention activities, were important to keeping POLs engaged in the intervention. Further, booster training sessions were critical to maintain the message of the project and ensure that the challenges POLs face with implementing the programs were addressed in a timely manner. Conclusion Recruiting POLs in a Tanzanian urban setting and engaging them in STI and IPV reduction through social networks is possible. Training POLs in health information and interpersonal communication is important. Utilizing booster sessions and a variety of retention strategies for POLs in programs that aim to reduce IPV and STI infections among young men is essential to maintain the health leaders’ engagement in the intervention as well as intervention fidelity.

Correlates of Anxiety and Depression among Young Men Living in Dar Es Salaam, Tanzania
Depression and anxiety are important sources of morbidity globally, but we have little knowledge of risk groups and risk factors for both classes of disorders in Tanzania and other low-resource settings. We aimed to identify sociodemographic markers and risk and protective factors associated with symptoms of anxiety and depression among 1249 young men belonging to social groups known as “camps” in Dar es Salaam. Anxiety and depression were measured using the HSCL-25. Twenty-two percent of men reported clinically significant symptoms of depression and 20% reported clinically significant symptoms of anxiety. Men living apart from family reported greater symptoms of anxiety and depression than men living with family, and employment was associated with a greater likelihood of clinically significant symptoms of both anxiety and depression. Childhood experience of violence was strongly associated with both anxiety and depression. Social support was associated with lower levels of anxiety and depression, and with a lower likelihood of clinically significant levels of anxiety and depression. Youth not living with family and the working poor may be important populations for future investigation. Interventions targeting survivors of childhood violence and social support-based interventions should be tested to address the burden of anxiety and depression in this setting.

Effect of the PREPARE intervention on sexual initiation and condom use among adolescents aged 12–14: a cluster randomised controlled trial in Dar es Salaam, Tanzania
Unsafe sexual practices continue to put adolescents at risk for a number of negative health outcomes in Tanzania. While there are some effective theory-based intervention packages with positive impact on important mediators of sexual behaviours, a context specific and tested intervention is urgently needed in Tanzania. To develop and evaluate an intervention that will have a significant effect in reducing sexual initiation and promoting condom use among adolescents aged 12–14 in Dar es Salaam, Tanzania. A school-based Cluster Randomised Controlled Trial was conducted during 2011–2014 in Kinondoni Municipality. A total of 38 public primary schools were randomly selected, of which half were assigned to the intervention and half to the control group based on their size and geographic location. Participants were interviewed using a self-administered questionnaire at baseline before the PREPARE intervention and then, 6 and 12 months following intervention. The primary outcomes were self-reported sex initiation and condom use during the past 6 months. Data analysis was done using Generalized Estimating Equation (GEE) modelling controlling for repeated measures and clustering of students within schools. A total of 5091 students were recruited at baseline, and interviewed again at 6 (n = 4783) and 12 months (n = 4370). Mean age of participants at baseline was 12.4 years. Baseline sociodemographic, psychometric and behavioural characteristics did not significantly differ between the two study arms. The GEE analysis indicated that the intervention had a significant effect on sexual initiation in both sexes after controlling for clustering and correlated repeated measures. A significantly higher level of action planning to use condoms was reported among female adolescent in the intervention arm than those in the control arm (p = 0.042). An effect on condom use behaviour was observed among male adolescent (p = 0.004), but not among female (p = 0.463). The PREPARE intervention had an effect in delaying self-reported sexual initiation among adolescents aged 12–14 in Dar es Salaam Tanzania. The intervention positively influenced action planning to use condoms for both sexes and increased actual condom use among male adolescents only. Future interventions addressing adolescent sexual and reproductive health should focus on impacting mediators of behaviour change.

Anxiety and depression strongly associated with sexual risk behaviors among networks of young men in Dar es Salaam, Tanzania
This study tested the association between mental health scores and sexual risk behaviors among male members of social groups known as “camps” in Dar es Salaam, Tanzania. Anxiety and depression were measured using the HSCL-25 and condom use and sexual partner concurrency were assessed through self-report. A total of 1113 sexually active men with an average age of 27 years were included in the analyses. Higher anxiety and depression scores were significantly associated with both condom use (Anxiety AOR = 0.58, 95% CI: 0.44, 0.77; Depression AOR = 0.60, 95% CI: 0.47, 0.77) and concurrency (Anxiety AOR = 2.32, 95% CI: 1.73, 3.12; Depression AOR = 2.08, 95% CI: 1.60, 2.70). The results of this study provide information salient to the development of effective HIV prevention interventions targeting populations with high burdens of anxiety and depression. The feasibility and effect of integrating mental health promotion activities into HIV prevention interventions should be explored.

Parenting practices and styles associated with adolescent sexual health in Dar es Salaam, Tanzania
Parenting styles and practices are suggested to be important predictors of adolescent sexual health, mostly in Europe and North America. Limited research has been conducted on these processes in Sub-Saharan Africa, which has different patterns of adolescent sexual behavior and family traditions. This study qualitatively explored parenting practices and styles associated with adolescent sexual health in Tanzania, with 12 adolescents and 12 parents of adolescents. The themes we identified from the data included parental monitoring, preventive, and punitive behaviors. Parents were reported to use mostly punitive behaviors to correct or prohibit sexual behavior; parents also set clear rules about appropriate sexual behavior (e.g., modesty and abstinence). Parents were also reported to closely monitor their adolescent children’s friendships and sexual behavior to minimize sexual behavior. However, some parents also engaged in positive preventive practices aimed at protecting their adolescent children.
