School health and nutrition programmes are effective strategies to address the health problems among school‐going children and adolescents. We examined the policy environments, successes and bottlenecks associated with school health and nutrition programmes in Tanzania. We used the ‘policy triangle framework’ to examine 22 national and regional school health and nutrition policies and programmes in Tanzania. We also interviewed 16 key informants to gain further insights into school health and nutrition programmes. Several school health and nutrition policies in Tanzania outline the basic elements of school‐based health and nutrition services. Yet, these documents neither recognise vulnerable groups, recommend age‐appropriate strategies to address children's and adolescents' varied and transient needs, nor provide a framework for implementing and tracking recommended activities. In these documents, underweight and infectious diseases, including human immunodeficiency virus/acquired immunodeficiency syndrome, are frequently identified as major concerns of young people, with little or no consideration of social determinants. Diverse strategies including school feeding, water and sanitation services, health and nutrition education and promotion of healthy behaviours are identified. In doing so, these documents adequately define the roles and responsibilities of all government actors, but young people and their guardians are not actively engaged in design and implementation. Additionally, there are several challenges to implementing these policies including budgetary constraints, limited resources, a lack of inter‐sectoral coordination and insufficient capacity within targeted schools. To improve the health and nutritional status of school‐going children and adolescents in Tanzania, adequate budgets, strengthened coordination and implementation efforts, the development of school‐based stakeholders' capacity, as well as the involvement of all other stakeholders, including adolescents, are imperative. In Tanzania, we reviewed school health and nutrition policies and programmes and supplemented them with expert interviews using the policy analysis triangle. Although based on evidence, the national programme in Tanzania is hampered by budgetary constraints, limited resources, lack of inter‐sectoral coordination and insufficient capacity. Key points School health and nutrition programmes protect and promote students' health, safety, and well‐being. Our study examined 22 national and regional school health and nutrition policies and programmes in Tanzania based on the ‘policy triangle framework’, to uncover policy environments, successes and bottlenecks. The results of this exercise were supplemented with interviews with 16 key informants to gain more insight into school health and nutrition programmes. Although school‐based strategies for adolescent health and nutrition have sound intentions, their implementation is patchy in Tanzania. School nutrition interventions need to be integrated and policy‐mandated to maximise their potential.

Background In many countries, rates of facility-based childbirth have increased substantially in recent years. However, insufficient attention has been paid to the acceptability and quality of maternal health services provided at facilities and, consequently, maternal health outcomes have not improved as expected. Disrespect and abuse during childbirth is increasingly being recognized as an indicator of overall poor quality of care and as a key barrier to achieving improved maternal health outcomes, but little evidence exists to describe the scope and magnitude of this problem, particularly in urban areas in low-income countries. Methods This paper presents findings from an assessment of the prevalence of disrespectful and abusive behaviors during facility-based childbirth in one large referral hospital in Dar es Salaam, Tanzania. Client reports of disrespect and abuse (D&A) were obtained through postpartum interviews immediately before discharge from the facility with 1914 systematically sampled women and from community follow-up interviews with 64 women four to six weeks post-delivery. Additionally, 197 direct observations of the labor, delivery, and postpartum period were conducted to document specific incidences of disrespect and abuse during labor and delivery, which we compared with women’s reports. Results During postpartum interviews, 15 % of women reported experiencing at least one instance of D&A. This number was dramatically higher during community follow-up interviews, in which 70 % of women reported any experience of D&A. During postpartum interviews, the most common forms of D&A reported were abandonment (8 %), non-dignified care (6 %), and physical abuse (5 %), while reporting for all categories of D&A, excluding detention and non consented care, was above 50 % during community follow-up interviews. Evidence from direct observations of client-provider interactions during labor and delivery confirmed high rates of some disrespectful and abusive behaviors. Conclusions This study is one of the first to quantify the prevalence of disrespect and abuse during facility-based childbirth in a large public hospital in an urban setting. The difference in respondent reports between the two time periods is striking, and more research is needed to determine the most appropriate methodologies for measuring this phenomenon. The levels and types of disrespect and abuse reported here represent fundamental violations of women’s human rights and are symptomatic of failing health systems. Action is urgently needed to ensure acceptable, quality, and dignified care for all women.

Home delivery and late and infrequent attendance at antenatal care (ANC) are responsible for substantial avoidable maternal and pediatric morbidity and mortality in sub-Saharan Africa. This cluster-randomized trial aimed to determine the impact of a community health worker (CHW) intervention on the proportion of women who (i) visit ANC fewer than 4 times during their pregnancy and (ii) deliver at home. As part of a 2-by-2 factorial design, we conducted a cluster-randomized trial of a home-based CHW intervention in 2 of 3 districts of Dar es Salaam from 18 June 2012 to 15 January 2014. Thirty-six wards (geographical areas) in the 2 districts were randomized to the CHW intervention, and 24 wards to the standard of care. In the standard-of-care arm, CHWs visited women enrolled in prevention of mother-to-child HIV transmission (PMTCT) care and provided information and counseling. The intervention arm included additional CHW supervision and the following additional CHW tasks, which were targeted at all pregnant women regardless of HIV status: (i) conducting home visits to identify pregnant women and refer them to ANC, (ii) counseling pregnant women on maternal health, and (iii) providing home visits to women who missed an ANC or PMTCT appointment. The primary endpoints of this trial were the proportion of pregnant women (i) not making at least 4 ANC visits and (ii) delivering at home. The outcomes were assessed through a population-based household survey at the end of the trial period. We did not collect data on adverse events. A random sample of 2,329 pregnant women and new mothers living in the study area were interviewed during home visits. At the time of the survey, the mean age of participants was 27.3 years, and 34.5% (804/2,329) were pregnant. The proportion of women who reported having attended fewer than 4 ANC visits did not differ significantly between the intervention and standard-of-care arms (59.1% versus 60.7%, respectively; risk ratio [RR]: 0.97; 95% CI: 0.82-1.15; p = 0.754). Similarly, the proportion reporting that they had attended ANC in the first trimester did not differ significantly between study arms. However, women in intervention wards were significantly less likely to report having delivered at home (3.9% versus 7.3%; RR: 0.54; 95% CI: 0.30-0.95; p = 0.034). Mixed-methods analyses of additional data collected as part of this trial suggest that an important reason for the lack of effect on ANC outcomes was the perceived high economic burden and inconvenience of attending ANC. The main limitations of this trial were that (i) the outcomes were ascertained through self-report, (ii) the study was stopped 4 months early due to a change in the standard of care in the other trial that was part of the 2-by-2 factorial design, and (iii) the sample size of the household survey was not prespecified. A home-based CHW intervention in urban Tanzania significantly reduced the proportion of women who reported having delivered at home, in an area that already has very high uptake of facility-based delivery. The intervention did not affect self-reported ANC attendance. Policy makers should consider piloting, evaluating, and scaling interventions to lessen the economic burden and inconvenience of ANC.

Alcohol consumption in Tanzania exceeds the global average. While sociodemographic difference in alcohol consumption in Tanzania have been studied, the relationship between psycho-cognitive phenomena and alcohol consumption has garnered little attention. Our study examines how depressive symptoms and cognitive performance affect alcohol consumption, considering sociodemographic variations. We interviewed 2299 Tanzanian adults, with an average age of 53 years, to assess their alcohol consumption, depressive symptoms, cognitive performance, and sociodemographic characteristics using a zero-inflated negative binomial regression model. The logistic portion of our model revealed that the likelihood alcohol consumption increased by 8.4% (95% confidence interval [CI] 3.6%, 13.1%, p  < 0.001) as depressive symptom severity increased. Conversely, the count portion of the model indicated that with each one-unit increase in the severity of depressive symptoms, the estimated number of drinks decreased by 2.3% (95% CI [0.4%, 4.0%], p  = .016). Additionally, the number of drinks consumed decreased by 4.7% (95% CI [1.2%, 8.1%], p  = .010) for each increased cognitive score. Men exhibited higher alcohol consumption than women, and Christians tended to consume more than Muslims. These findings suggest that middle-aged and elderly adults in Tanzania tend to consume alcohol when they feel depressed but moderate their drinking habits by leveraging their cognitive abilities.

Background In Tanzania, loss to follow-up (LTFU) among adolescents and young adults living with HIV (AYLHIV) presents a significant challenge. A retrospective cohort study analysing data found that approximately 42% of adolescents on antiretroviral therapy (ART) were LTFU between 2014 to 2016. This study examined the predictors of LTFU among AYLHIV in Dar es Salaam during their first year of ART treatment. Methods This retrospective cohort study utilized routine data collected in care and treatment centres among adolescents and young adults aged 10–24 years living with HIV in Dar es Salaam who were enrolled in HIV care from 2015–2019. The data were analysed using STATA 14. Descriptive statistics were summarized using frequencies and proportions. Kaplan–Meier method was used to determine failure probabilities within one year of ART initiation. The Fine and Gray test was conducted to report adjusted sub-hazard ratios (aSHRs) and cumulative incidence estimates for LTFU within one year of ART initiation, accounting for mortality as a competing risk. Results A total of 15,874 AYLHIVs enrolled in Care and Treatment Clinics between 2015 and 2019 were studied. The majority (10,913, 68.7%) were young adults, and 13,160 (84.4%) were female. The percentage of LTFUs within one year of ART initiation was 15%. The significant predictors of LTFU were age 20–24 years, having a CD4 cell count between 350 and 499, receiving care in healthcare facilities located in the Ubungo district and being enrolled in care between 2018 and 2019. Receiving care at private healthcare facilities, having a tuberculosis co-infection, and being classified as WHO Stage III were all associated with a reduced risk of LTFU in ART care. Conclusion This study found that adolescents and young people in Tanzania experience 15% rates of LTFU in ART care, within one year of ART initiation. Therefore, HIV service providers need to pay particular attention to the AYLHIV and factors that influence LTFU in ART care. The increasing incidence of LTFU necessitates the implementation of effective and friendly tracing interventions to identify AYLHIV patients who have become LTFU to re-engage them in care.

Background Several recent studies have attempted to measure the prevalence of disrespect and abuse (D&A) of women during childbirth in health facilities. Variations in reported prevalence may be associated with differences in study instruments and data collection methods. This systematic review and comparative analysis of methods aims to aggregate and present lessons learned from published studies that quantified the prevalence of Disrespect and Abuse (D&A) during childbirth. Methods We conducted a systematic review of the literature in accordance with PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analysis) guidelines. Five papers met criteria and were included for analysis. We developed an analytical framework depicting the basic elements of epidemiological methodology in prevalence studies and a table of common types of systematic error associated with each of them. We performed a head-to-head comparison of study methods for all five papers. Using these tools, an independent reviewer provided an analysis of the potential for systematic error in the reported prevalence estimates. Results Sampling techniques, eligibility criteria, categories of D&A selected for study, operational definitions of D&A, summary measures of D&A, and the mode, timing, and setting of data collection all varied in the five studies included in the review. These variations present opportunities for the introduction of biases – in particular selection, courtesy, and recall bias – and challenge the ability to draw comparisons across the studies’ results. Conclusion Our review underscores the need for caution in interpreting or comparing previously reported prevalence estimates of D&A during facility-based childbirth. The lack of standardized definitions, instruments, and study methods used to date in studies designed to quantify D&A in childbirth facilities introduced the potential for systematic error in reported prevalence estimates, and affected their generalizability and comparability. Chief among the lessons to emerge from comparing methods for measuring the prevalence of D&A is recognition of the tension between seeking prevalence measures that are reliable and generalizable, and attempting to avoid loss of validity in the context where the issue is being studied.

With the increase in people living with HIV in sub-Saharan Africa and expanding eligibility criteria for antiretroviral therapy (ART), there is intense interest in the use of novel delivery models that allow understaffed health systems to successfully deal with an increasing demand for antiretroviral drugs (ARVs). This pragmatic randomized controlled trial in Dar es Salaam, Tanzania, evaluated a novel model of ARV community delivery: lay health workers (home-based carers [HBCs]) deliver ARVs to the homes of patients who are clinically stable on ART, while nurses and physicians deliver standard facility-based care for patients who are clinically unstable. Specifically, the trial aimed to assess whether the ARV community delivery model performed at least equally well in averting virological failure as the standard of care (facility-based care for all ART patients). The study took place from March 1, 2016, to October 27, 2017. All (48) healthcare facilities in Dar es Salaam that provided ART and had an affiliated team of public-sector HBCs were randomized 1:1 to either (i) ARV community delivery (intervention) or (ii) the standard of care (control). Our prespecified primary endpoint was the proportion of adult non-pregnant ART patients with virological failure at the end of the study period. The prespecified margin of non-inferiority was a risk ratio (RR) of 1.45. The mean follow-up period was 326 days. We obtained intent-to-treat (ITT) RRs using a log-binomial model adjusting standard errors for clustering at the level of the healthcare facility. A total of 2,172 patients were enrolled at intervention (1,163 patients) and control (1,009 patients) facilities. Of the 1,163 patients in the intervention arm, 516 (44.4%) were both clinically stable on ART and opted to receive ARVs in their homes or at another meeting point of their choosing in the community. At the end of the study period, 10.9% (95/872) of patients in the control arm and 9.7% (91/943) in the intervention arm were failing virologically. The ITT RR for virological failure demonstrated non-inferiority of the ARV community delivery model (RR 0.89 [1-sided 95% CI 0.00-1.18]). We observed no significant difference between study arms in self-reported patient healthcare expenditures over the last 6 months before study exit. Of those who received ARVs in the community, 97.2% (95% CI 94.7%-98.7%) reported being either \"satisfied\" or \"very satisfied\" with the program. Other than loss to follow-up (18.9% in the intervention and 13.6% in the control arm), the main limitation of this trial was that substantial decongestion of healthcare facilities was not achieved, thus making the logic for our preregistered ITT approach (which includes those ineligible to receive ARVs at home in the intervention sample) less compelling. In this study, an ARV community delivery model performed at least as well as the standard of care regarding the critical health indicator of virological failure. The intervention did not significantly reduce patient healthcare expenditures, but satisfaction with the program was high and it is likely to save patients time. Policy-makers should consider piloting, evaluating, and scaling more ambitious ARV community delivery programs that can reach higher proportions of ART patients. ClinicalTrials.gov NCT02711293.

To curb HIV infection rate in Tanzania, antiretroviral therapy (ART) has been scaled up since 2006, and in 2019, the country shifted to regimen including dolutegravir as a default first line. We assessed the success of ART and the contribution of HIV drug resistance (HIVDR) to unsuppressed viral loads. Between February and May 2023 a cross-sectional survey with random sampling was conducted in the six clinics in an urban cohort in Dar es Salaam. Patients with unsuppresed viral loads (local criteria viral load (VL) ≥ 1000 copies/mL) were tested for HIVDR mutations using the WHO adapted protocol for plasma samples. Mutations were interpreted using the Stanford HIVDR database. In total 600 individuals participated in this survey, the majority were female (76.83%), mean age ( ± standard deviation) was 44.0 ( ± 11.6) years. The median duration on ART (interquartile range) was 6.5 (3.9–10.2) years. Approximately 99% were receiving tenofovir + lamivudine + dolutegravir as a fixed dose combination. VL testing was successful in 99.67% (598/600) of survey patients and only 33 had VL ≥ 1000 copies/mL, resulting in a viral suppression level of 94.48% (565/598, 95% CI 92.34–96.17%). For 23 samples, protease and reverse transcriptase (RT) genotyping were successful, with 13 sequences containing RT inhibitor surveillance drug resistance mutations (SDRMs) (56.5%). No SDRM against protease inhibitors were detected. Thirty samples were successfully genotyped for integrase with 3 sequences (10.08%) containing integrase strand transfer inhibitor (INSTI) SDRMs. In samples successfully genotyped in the three genetic regions, 68.18% (16/22) had a genotypic susceptibility score (GSS) ≥ 2.5 for the concurrent regimen, implying factors beyond drug resistance caused the unsuppressed viral load. For five patients, GSS indicated that HIVDR may have caused the unsuppressed viral load. All three patients with INSTI resistance mutations were highly resistant to dolutegravir and accumulated nucleoside and non-nucleoside RT inhibitor HIVDR mutations. Although in this cohort the last 95 UNAIDS target was almost achieved, HIVDR mutations, including INSTIs resistance mutations were detected in HIV-positive individuals taking ART for at least one year. We recommend the design and implementation of high-impact interventions to prevent the increase of HIVDR, failure of dolutegravir and address the non-resistance factors in the study area.

Pre-Exposure Prophylaxis (PrEP) has demonstrated efficacy in preventing HIV infection. Female Bar Workers (FBWs) often act as informal sex workers, placing them at risk of HIV infection. Despite expressing interest in PrEP, FBWs face barriers to accessing public-sector clinics where PrEP is delivered. We developed a study to compare the effectiveness of workplace-based PrEP provision to standard-of-care facility-based provision for PrEP initiation, retention and adherence among FBWs. In this double-randomized intervention study, FBWs aged 15 years and above will be screened, consented and initiated on PrEP (emtricitabine/tenofovir disoproxil), and followed for six months. Participants will be randomized at the bar level and offered PrEP at their workplace or at a health facility. Those who are initiated will be independently individually randomized to either receive or not receive an omni-channel PrEP champion intervention (support from an experienced PrEP user) to improve PrEP adherence. We expect to screen 1,205 FBWs to enroll at least 160 HIV negative women in the study. Follow-up visits will be scheduled monthly. HIV testing will be performed at baseline, month 1, 4 and 6; and TDF testing at months 2 and 6. Primary outcomes for this trial are: (1) initiation on PrEP (proportion of those offered PrEP directly observed to initiate PrEP); and (2) adherence to PrEP (detectable urine TDF drug level at 6-months post-enrollment). The primary outcomes will be analyzed using Intention-to-Treat (ITT) analyses. Using a randomized trial design, we will evaluate two interventions aiming to reduce barriers to uptake and retention on PrEP among FBWs, a vulnerable population at risk of HIV acquisition and onward transmission. If these interventions prove effective in promoting PrEP among FBWs, they could assist in abating the HIV epidemic in Africa.

Background HIV infection can cause malabsorption and rapid utilization of nutrients. A randomized trial of multivitamin supplementation among people living with HIV/AIDS (PLWHA) initiating antiretroviral therapy (ART) in Tanzania was stopped early due to increased alanine aminotransferase (ALT) concentrations in the multiple recommended dietary allowances (RDA) multivitamin group. We conducted detailed analysis to assess the effect of multivitamins on ALT elevations and evaluate whether subgroups of PLWHA have greater hepatotoxicity risks associated with the use of high-dose multivitamins. Methods We utilized data from a randomized, double-blind trial conducted in 2006–2009 that assessed the effect of high-dose multivitamins that contained vitamin B complex, vitamin C, and vitamin E at multiple RDA as compared to standard-dose multivitamins containing single RDAs among adults initiating ART in Tanzania. We evaluated the effect of high-dose multivitamins on incident mild/moderate ALT elevations > 40 IU/L, persistent ALT elevations > 40 IU/L (2 + clinic visits), and severe ALT elevations > 200IU/L using Cox proportional hazard models. We then evaluated effect modification by patient characteristics to determine if subgroups of PLWHA experienced different magnitudes of risk for ALT elevations associated with high-dose multivitamins. Results High-dose multivitamins increased the risk of incident mild/moderate ALT elevations > 40 IU/mL as compared to standard-dose multivitamins (hazard ratio (HR): 1.41; 95%CI: 1.26,1.58) as well as incident sustained mild/moderate ALT elevations (HR: 1.19; 95%CI: 1.04,1.36), but there was no overall effect on severe ALT elevations (HR: 1.44; 95% CI: 0.91,2.28). There was no evidence that the effect of high-dose multivitamins on any or sustained mild/moderate ALT elevations was modified by any patient characteristic. However, CD4 T-cell count was found to modify the effect of high-dose multivitamins on severe ALT elevations ( p -value for interaction:0.01). Among participants with a baseline CD4 T-cell count ≤ 100 cells/µL, individuals receiving high-dose multivitamins had 3.74 times (95%CI: 1.52–9.17) the risk of incident severe ALT elevations compared to standard-dose multivitamins, while participants with CD4 T-cell counts > 100 cells/µL, appeared to have no effect of high-dose multivitamins on severe ALT elevations (HR:0.92; 95% CI: 0.50,1.67). Conclusions High-dose RDA multivitamin supplementation increased the incidence of any mild to moderate ALT elevations among adults starting ART in Tanzania and the magnitude of the risk does not appear to differ by patient characteristics. However, immunocompromised PLWHA with CD4 T-cell counts < 100 cells/µL may experience greater risk of severe ALT elevations associated with the use of high-dose multivitamins. Although the study findings offer significant insights, it is essential to take into account limitations imposed by newer cART regimes.
