    Background: Mother-to-child transmission of HIV remains an important public health problem in sub-Saharan Africa. As HIV testing and linkage to PMTCT occurs in antenatal care (ANC), major challenges for any PMTCT option in developing countries, including Tanzania, are delays in the first ANC visit and a low overall number of visits. Community health workers (CHWs) have been effective in various settings in increasing the uptake of clinical services and improving treatment retention and adherence. At the beginning of this trial in January 2013, the World Health Organization recommended either of two medication regimens, Option A or B, for prevention of mother-to-child transmission of HIV (PMTCT). It is still largely unclear which option is more effective when implemented in a public healthcare system. This study aims to determine the effectiveness, cost-effectiveness, acceptability, and feasibility of: (1) a community health worker (CWH) intervention and (2) PMTCT Option B in improving ANC and PMTCT outcomes. Methods/Design This study is a cluster-randomized controlled health systems implementation trial with a two-by-two factorial design. All 60 administrative wards in the Kinondoni and Ilala districts in Dar es Salaam were first randomly allocated to either receiving the CHW intervention or not, and then to receiving either Option B or A. Under the standard of care, facility-based health workers follow up on patients who have missed scheduled appointments for PMTCT, first through a telephone call and then with a home visit. In the wards receiving the CHW intervention, the CHWs: (1) identify pregnant women through home visits and refer them to antenatal care; (2) provide education to pregnant women on antenatal care, PMTCT, birth, and postnatal care; (3) routinely follow up on all pregnant women to ascertain whether they have attended ANC; and (4) follow up on women who have missed ANC or PMTCT appointments.

    Mental health in adolescence is important for health and well-being throughout the life course, but evidence from Sub-Saharan Africa is sparse. This study aimed to assess the correlates of internalizing, externalizing and cumulative problems among early adolescents. This study used cross-sectional survey data from 3516 school-going adolescents in Ouagadougou, Burkina Faso; Addis Ababa, Ethiopia and Dar es Salaam, Tanzania. We used a 25-item Strengths and Difficulties Questionnaire to measure internalizing, externalizing and cumulative problems. We carried out multi-variable linear regression analyses with the estimation of adjusted mean differences and 95% confidence intervals, to determine the factors associated with internalizing, externalizing and cumulative problems. Overall, 1 in 8 adolescents had internalizing problems, while 1 in 10 had externalizing problems. In two sites, having friends was related to lower internalizing problems, while repeating a grade, physical fights and household food insecurity were related to greater internalizing problems. Household food insecurity and involvement in physical fights were associated with greater externalizing problems across sites, while repeating a grade was linked with greater externalizing problems in two sites. Having a caring adult in school was associated with fewer externalizing problems across sites, while having friends was associated with fewer externalizing problems in two sites. Overall, having friends was related to fewer cumulative problems, while physical fights and household food insecurity were related to higher cumulative problems. School-based mental health and food programs may be useful in addressing social-emotional problems among school-aged adolescents in Burkina Faso, Ethiopia and Tanzania

    Adolescents face the risk of the triple burden of malnutrition—the co‐existence of micronutrient deficiencies, underweight and overweight and obesity and related non-communicable diseases. Poor‐quality diets are a modifiable risk factor for all forms of malnutrition in adolescents. However, there is limited knowledge about diet quality for African adolescents. We analyzed data from 4609 school‐going adolescents aged 10–15 years in Burkina Faso, Ethiopia, Sudan and Tanzania. Dietary intake was assessed using food frequency questionnaires, and diet quality computed using the Global Diet Quality Score (GDQS). Generalized estimating equations linear regression models were used to evaluate factors associated with adolescent diet quality. Mean adolescent age was 12.4 (±1.4) years and 54% of adolescents were female. Adolescents reported physical activity on 1.5 (±1.7) days/week. The mean GDQS (±SD) was 20.6 (±4.0) (maximum 40). Adolescent consumption of vegetables, fruit, nuts and seeds, eggs, fish and poultry was low, and refined grain consumption was relatively high. Boys consumed unhealthy foods less frequently but consumed fewer cruciferous vegetables and deep orange tubers. Older adolescents had higher fish and lower red meat consumption. Having an unemployed mother versus farmer (estimate−2.60, 95% confidence interval [CI]:−4.81,−0.39), and having 3–4 days of physical activity per week versus none(estimate 0.64, 95% CI: 0.11, 1.17) were associated with GDQS. We found evidence of poor‐quality adolescent diets and gender and age differences in the consumption of healthy diets. Programs to address poor‐quality diets should consider tailoring interventions for adolescent girls and boys of different ages and also consider the role of physical activity in these contexts

    Digital technologies provide unprecedented opportunities for health and nutrition interventions among adolescents. The use of digital media and devices among young adolescents across diverse settings in sub-Saharan Africa is unclear. This cross-sectional study aimed to assess the use of digital media and devices and the socioeconomic determinants of use among young adolescents in Burkina Faso, Ethiopia, South Africa, Sudan and Tanzania. The study included 4981 adolescents aged 10-15 from public schools selected by multistage sampling. Access to various digital media and devices was self-reported by adolescents. Logistic regression models were used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) for the associations between sociodemographic characteristics and access to digital media and devices. Approximately 40% of the adolescents in Burkina Faso and South Africa, 36% in Sudan, 13% in Ethiopia and 3% in Tanzania owned mobile phones. Compared with boys, girls had a lower ownership of mobile phones (odds ratio [OR] = 0.79; 95% confidence interval [CI]: 0.68, 0.92; p = 0.002), computers (OR = 0.83; 95% CI: 0.70, 0.99; p = 0.04) and social media accounts (OR = 0.68; 95% CI: 0.56, 0.83; p < 0.001). Higher maternal education and greater household wealth were positively associated with access to digital media and devices. While digital media and devices are promising platforms for interventions in some settings due to relatively high levels of access, their utility in delivering health and nutrition interventions to adolescents in these contexts should be further examined

    Anaemia among adolescents is a global health problem. However, evidence regarding its burden and risk factors, particularly for younger adolescents and in sub-Saharan Africa (SSA), remains scarce. We aimed to assess the prevalence and potential determinants of anaemia among urban and semi-urban in-school young adolescents in Ethiopia, Sudan and Tanzania. We conducted a school-based survey among 3558 adolescents aged 10-14 years. A capillary blood sample was used to assess haemoglobin concentration. We assessed anaemia prevalence and examined associations between measures at the individual, household and school levels and anaemia using Poisson regression models adjusted for school and country-level clustering. The prevalence of anaemia was 32.0% overall, and 10.8% in Ethiopia, 25.0% in Sudan and 58.3% in Tanzania. Being a boy [adjusted risk ratio (RR): 1.11, 95% confidence interval (CI): 1.08-1.15, p < 0.001], poorer diet quality (RR: 1.12, 95% CI: 1.02-1.23 p = 0.015), no school handwashing stations (RR: 1.26, 95% CI: 1.20-1.32, p < 0.001) and food insecurity (RR for moderate/severe anaemia: 1.06, 95% CI: 1.02-1.10, p = 0.002) were associated with increased anaemia risk. Younger age (RR: 0.91, 95% CI: 0.86-0.96, p < 0.001) and increasing height-for-age z-score (RR: 0.93, 95% CI: 0.91-0.95, p < 0.001) were associated with decreased anaemia risk. Associations were consistent for moderate or severe anaemia. There was no evidence of effect modification by sex. This study highlights anaemia as a public health problem and identified nutritional, dietary and hygiene measures as key risk factors of anaemia among young adolescents in SSA. School-based interventions addressing these factors could reduce the burden of anaemia in adolescence
