Antiretroviral therapy (ART) has improved the survival of people living with HIV (PLHIV) but this success has been accompanied by an increase in noncommunicable diseases. We conducted a prospective cohort study of 4000 adult PLHIV who were initiating ART in Dar es Salaam, Tanzania, to assess weight gain during the first year of treatment and associated sociodemographic and clinical factors. Anthropometric data were collected at ART initiation and monthly follow-up visits.

Although vitamin D-3 supplementation has purported anti-inflammatory properties, its ability to ameliorate biomarkers of EED remains unclear.
Objectives: This study aimed to examine the effects of maternal vitamin D-3 supplementation during pregnancy and lactation on biomarkers of EED, systemic inflammation, and growth in women living with HIV and their infants in Dar es Salaam, Tanzania.
Background: Small incentives could improve engagement in HIV care. We evaluated the short-term and longer-term effects of financial incentives for visit attendance on viral suppression among adults initiating antiretroviral therapy (ART) in Tanzania.
Methods: In a type 1 hybrid effectiveness-implementation study, we randomised (1:1) 32 primary care HIV clinics in four Tanzanian regions to usual care (control group) or the intervention (usual care plus ≤6 monthly incentives [22 500 Tanzanian Shillings, about US$10, each], conditional on visit attendance).
Objective: Assess the risk of death for offspring of pregnant women with HIV (PWHIV) and the association with sociodemographic, pregnancy, HIV-related, and birth factors.
Design: We conducted a prospective cohort study of PWHIV on antiretroviral therapy (ART) and their offspring in urban Tanzania who were enrolled in a vitamin D trial conducted from June 2015 to October 2019.
Methods: We described rates of fetal, neonatal, and infant death and assessed risk factors for these outcomes with generalized estimating equations.
Background: Anemia may be associated with poor clinical outcomes among people living with human immunodeficiency virus (HIV) (PLHIV) despite highly active antiretroviral therapy (HAART). There are concerns that iron supplementation may be unsafe to prevent and treat anemia among PLHIV.
Objective: The objective of the study was to evaluate the associations of anemia and iron supplementation with mortality and viral load among PLHIV in Tanzania.
Background: Economic incentives can improve clinical outcomes among in-care people living with HIV (PLHIV), but evidence is limited for their effectiveness among out-of-care PLHIV or those at risk of disengagement. We propose a type 1 hybrid effectiveness-implementation study to advance global knowledge about the use of economic incentives to strengthen the continuity of HIV care and accelerate global goals for HIV epidemic control.
Methods: The Rudi Kundini, Pamoja Kundini study will evaluate two implementation models of an economic incentive strategy for supporting two groups of PLHIV in Tanzania.
Purpose: We evaluate contraceptive use and pregnancy two years following an intervention in Tanzania, which provided antenatal post-partum family planning counselling and post-partum intrauterine device (PPIUD) services following delivery.
Methods: We analyse data from five hospitals in Tanzania using a difference-in-difference cluster randomised design, with randomisation at the hospital level. We use women-level data collected at the index birth and a follow-up survey two years later among 6,410 women.
Background: Economic incentives can improve clinical outcomes among in-care people living with HIV (PLHIV), but evidence is limited for their effectiveness among out-of-care PLHIV or those at-risk of disengagement. We propose a type 1 hybrid effectiveness-implementation study to advance global knowledge about the use of economic incentives to strengthen the continuity of HIV care and accelerate global goals for HIV epidemic control.
Methods: The Rudi Kundini, Pamoja Kundini study will evaluate two implementation models of an economic incentive strategy for supporting two groups of PLHIV in Tanzania.
Background: An enhanced understanding of renal outcomes in persons with chronic HBV, HIV, and HBV/HIV coinfection is needed to mitigate chronic kidney disease in regions where HBV and HIV are endemic.
Objectives: To investigate changes in estimated glomerular filtration rate (eGFR) in adults with HBV, HIV or HBV/HIV enrolled in a 3 year prospective cohort study of liver outcomes in Dar es Salaam, Tanzania and initiated on antiviral therapy.
Methods: We compared eGFR between and within groups over time using mixed-effects models.
Background: Women who experience antenatal depression may be at increased risk of adverse birth outcomes. Few studies have examined this association among women living with HIV (WHIV).
Methods: We conducted a prospective cohort study of 2298 pregnant WHIV on antiretroviral therapy (ART) in Dar es Salaam, Tanzania, who were participants in a randomized trial of vitamin D supplementation.
Children born to mothers living with HIV may experience greater risk of poor growth and development outcomes than their HIV-unexposed peers. Few studies have examined the relationship between maternal depression and social support with infant growth and development in the context of HIV. We conducted a prospective cohort study of 2,298 pregnant women living with HIV in Dar es Salaam, Tanzania, assessing antenatal depression (Hopkins Symptoms Checklist-25) and social support (Duke-UNC Functional Social Support Questionnaire) at 12-27 weeks of gestation.

The School Readiness among HIV-Exposed Children (SRHEC) cohort study aims to assess the school readiness of preschool aged children born to women living with HIV and to identify the biological, environmental and social factors that contribute to school readiness in this population.
Methods And Analysis: The SRHEC cohort is an observational follow-up study of children born to HIV-infected pregnant women who were previously enrolled in a maternal vitamin D supplementation randomised, placebo-controlled trial in Dar es Salaam, Tanzania.
The provision of high-quality antenatal care (ANC) is important for preventing maternal and newborn mortality and morbidity, but only around half of pregnant women in Tanzania attended four or more ANC visits in 2019. Although there is emerging evidence on the benefit of community health worker (CHW) interventions on ANC uptake, few large-scale pragmatic trials have been conducted. This pragmatic cluster-randomized trial, implemented directly through the public sector health system, assessed the impact of an intervention that trained public sector CHWs to promote the uptake of ANC.

However, evaluation of broader patient-centred and unintended outcomes is critical to assess impacts on patient choice and autonomy. Here, we evaluate the effects of a postpartum intrauterine device (PPIUD) intervention on outcomes related to contraceptive method choice.

We examined the associations of EED biomarkers with birth outcomes in pregnant women living with human immunodeficiency virus in Dar es Salaam, Tanzania.
Methods: We performed a cohort study of 706 HIV-infected pregnant women.
Background: The influence of inflammation on iron status among people living with HIV (PLWHIV) has not been well explored. We evaluated the trajectory of iron status among PLWHIV during the first year of highly active antiretroviral therapy (HAART), compared alternative approaches for inflammation correction, and assessed the associations of iron status with HIV-1 viral load and anthropometric outcomes.
Methods: We conducted a secondary analysis of data from a randomized trial among 400 adults initiating HAART in Tanzania.
Background: Combination antiretroviral therapy (cART) initiation during pregnancy reduces the risk of perinatal human immunodeficiency virus (HIV) transmission; however, studies have suggested that there may be unintended adverse consequences on birth outcomes for selected cART regimens.
Methods: We analyzed adverse birth outcomes among a prospective cohort of 1307 pregnant women with HIV in Dar es Salaam who initiated cART during the first or second trimester of a singleton pregnancy. Our primary analysis compared birth outcomes by gestational age at cART initiation among these women initiating cART in pregnancy.
Background: Observational studies suggest that blood concentrations of 25-hydroxyvitamin D [25(OH)D] are associated with morbidity, viral suppression, and mortality among adults living with HIV.
Objectives: We evaluated the effect of cholecalciferol (vitamin D3) supplementation on the risk of HIV disease progression, HIV-1 viral suppression, comorbidities, weight change, and depression among HIV-infected individuals that were initiating antiretroviral therapy (ART) in Dar es Salaam, Tanzania.
Methods: We conducted a randomized, double-blind, placebo-controlled trial of vitamin D3 supplementation among 4000 HIV-infected adult men and nonpregnant women initiating ART with insufficient serum 25(OH)D concentrations (<30 ng/mL).
Background: Observational studies suggest that vitamin D deficiency among people living with HIV is associated with a greater risk of disease progression and death. Low levels of vitamin D in pregnancy are also associated with poor fetal and infant growth. Therefore, vitamin D supplementation may improve clinical outcomes for pregnant women living with HIV and improve fetal and postnatal growth for their infants.

Limited evidence suggests iron supplementation may have adverse effects among HIV-infected populations. We aimed to estimate the effect of iron supplement use on mortality, disease progression and haematological outcomes among HIV-infected children in Dar es Salaam, Tanzania.
View Article and Find Full Text PDFBackground: Programmes promoting the postpartum intrauterine device (PPIUD) have proliferated throughout South Asia and sub-Saharan Africa in recent years, with proponents touting this long-acting reversible contraceptive (LARC) method's high efficacy and potential to meet contraceptive unmet need. While critiques of LARC-first programming abound in the Global North, there have been few studies of the impact of LARC-centric programmes on patient-centred outcomes in the Global South.
Methods: Here, we explore the impact of a PPIUD intervention at five Tanzanian hospitals and their surrounding satellite clinics on quality of contraceptive counselling and person-centred care using 20 qualitative in-depth interviews with pregnant women seeking antenatal care at one of those clinics.
Limited information is available on the association between depression and viral suppression among people living with HIV (PLH) in sub-Saharan Africa. We conducted a prospective cohort study of 3996 adults initiating antiretroviral therapy (ART) in Dar es Salaam, Tanzania. Log-binomial models were used to assess the association between depression and the risk of an unsuppressed viral load (> 400 copies/mL) after 6 months of ART.
