Partnerships with religious leaders to promote family planning in rural Tanzania: an open-label, cluster randomised trial.

BACKGROUND: Family planning benefits maternal-child health, education, and economic wellbeing. Despite global efforts, an unsatisfied demand for family planning persists in sub-Saharan Africa. Based on previous successful partnerships, the aim of this study was to determine whether an educational intervention for religious leaders would increase community knowledge, demand for, and ultimately uptake of family planning. METHODS: In this open-label, cluster randomised trial in Tanzania, 24 communities were randomised (1:1) to intervention or control arm. Communities, defined as the catchment area of a single public health facility, were eligible if they were at least 15 km from Mwanza City and had not previously participated in a health intervention for religious leaders. Random allocations were determined by coin toss and were not revealed to clinicians at health facilities in intervention and control communities, nor to the data entry team; however, due to the nature of the intervention, masking of religious leaders in the intervention communities was not possible. All Christian religious institutions were invited to send four leaders to an educational intervention that incorporated cultural, theological, and medical teaching about family planning. The primary outcome was contraceptive uptake at the community health facility during the year post intervention versus the year before the intervention. This trial was registered at clinicaltrials.gov, NCT03594305. FINDINGS: 75 communities in three districts were assessed for eligibility. 19 communities were excluded and 56 were eligible for study inclusion and were placed in random order to be invited to participate. The first 24 communities that were invited agreed to participate and were randomly assigned to receive the educational intervention either during the trial or after trial completion. Between July 10, 2018 and Dec 11, 2021, we provided the intervention in 12 communities and compared contraceptive uptake with 12 control communities. All were followed up for 12 months. In intervention communities, contraceptive uptake increased by a factor of 1·47 (95% CI 1·41-1·53) in the post-intervention (prospective) versus pre-intervention (historical) year (geometric mean of contraceptive uptake, 466 in the prospective year vs 312 in the historical year), versus 1·24 (95% CI 1·20-1·29) in control communities (geometric mean, 521 in the prospective year vs 429 in the historical year). The rate of change in contraceptive uptake was greater in intervention communities (between-group ratio of geometric mean ratios over time, 1·19 [95% CI 1·12-1·25]; p<0·0001). The COVID-19 pandemic was associated with decreased contraceptive uptake (geometric mean, 365 during the pandemic in communities that had the majority of their prospective 12-month data collection periods occur after March 16, 2020, vs 494 before the pandemic; geometric mean ratio, 0·72 [95% CI 0·57-0·90]; p=0·0040). INTERPRETATION: This intervention offers a scalable model, leveraging influence of trusted religious leaders to increase knowledge and uptake of family planning. New strategies such as this could help to overcome setbacks that occurred during the COVID-19 pandemic.

Perspectives of Muslim Religious Leaders to Shape an Educational Intervention About Family Planning in Rural Tanzania: A Qualitative Study.

INTRODUCTION: Uptake of effective contraceptive methods can be hindered by poor understanding and uncertainty about its compatibility with religious beliefs. We sought to understand the perspectives of Muslim religious leaders in rural Tanzania on family planning (FP) and acceptable strategies for providing FP education to leaders and their communities. METHODS: We conducted in-depth interviews with Muslim leaders from 4 communities in northwest Tanzania. Open-ended questions explored leaders' views on FP in relation to their communities, Muslim texts and teaching, and their experience as leaders. We also investigated how FP education could be provided in their communities and asked practical questions regarding seminar implementation. Interviews were conducted in Kiswahili and transcribed and translated into English. Data were coded independently by 2 investigators using NVivo 1.5.1 and analyzed thematically. RESULTS: We interviewed 17 male and 15 female Muslim leaders. All leaders supported FP as a concept in which births are spaced, interpreting this as espoused by the Qur'an and a basic right of children raised in Islam. Leaders uniformly endorsed the use of breastfeeding and the calendar method to space births but had divergent and sometimes opposing views on other methods, including condom use, oral contraceptives, and intrauterine devices. All leaders acknowledged the need for FP education among their congregants and were in favor of helping to teach an FP seminar in their communities. CONCLUSION: Our data reveal insights into how education for Muslim leaders may equip them to promote birth spacing and enhance understanding of FP in their communities in ways that are concordant with Islamic teaching. Our findings will guide the design and pilot-testing of an educational intervention for Muslim religious leaders to promote knowledge and uptake of FP in rural Tanzania.

Religious Leaders as Trusted Messengers in Combatting Hypertension in Rural Tanzanian Communities.

BACKGROUND: Hypertension is a growing public health emergency in rural sub-Saharan Africa. Based on the known influence of religious leaders in rural sub-Saharan Africa and our prior research, we explored perspectives of religious leaders on hypertension and potential strategies to improve hypertension control in their communities. METHODS: We conducted 31 in-depth interviews with Christian (n = 17) and Muslim (n = 14) religious leaders in rural Tanzania. Interviews focused on religious leaders' perceptions of hypertension and how they could play a role in promoting blood pressure reduction. We used interpretative phenomenological analysis, a qualitative research method, to understand religious leaders' perspectives on, and experiences with, hypertension. RESULTS: Three main themes emerged during analysis. First, we found that perceptions about causes, treatment, and complications of hypertension are influenced by religious beliefs. Second, religious beliefs can enable engagement with hypertension care through religious texts that support the use of biomedical care. Third, religious leaders are enthusiastic potential partners for promoting hypertension control in their communities. These themes were consistent between religion and gender of the religious leaders. CONCLUSIONS: Religious leaders are eager to learn about hypertension, to share this knowledge with others and to contribute to improved health in their communities.

Cervicovaginal bacterial communities in reproductive-aged Tanzanian women with Schistosoma mansoni, Schistosoma haematobium, or without schistosome infection.

Schistosome infection is recognized as a potentially modifiable risk factor for HIV in women by the World Health Organization. Alterations in cervicovaginal bacteria have been associated with HIV acquisition and have not been studied in schistosome infection. We collected cervical swabs from Tanzanian women with and without S. mansoni and S. haematobium to determine effects on cervicovaginal microbiota. Infected women were treated, and follow-up swabs were collected after 3 months. 16S rRNA sequencing was performed on DNA extracted from swabs. We compared 39 women with S. mansoni with 52 uninfected controls, and 16 with S. haematobium with 27 controls. S. mansoni-infected women had increased abundance of Peptostreptococcus (p = 0.026) and presence of Prevotella timonesis (p = 0.048) compared to controls. High-intensity S. haematobium infection was associated with more diverse cervicovaginal bacterial communities than uninfected controls (p = 0.0159). High-intensity S. mansoni infection showed a similar trend (p = 0.154). At follow-up, we observed increased alpha diversity in S. mansoni (2.53 vs. 1.72, p = 0.022) and S. haematobium (2.05 vs. 1.12, p = 0.066) infection groups compared to controls. Modifications in cervicovaginal microbiota, particularly increased diversity and abundance of taxa associated with bacterial vaginosis and HIV (Peptostreptococcus, Prevotella), were associated with schistosome infection.

Insufficiency of annual praziquantel treatment to control Schistosoma mansoni infections in adult women: A longitudinal cohort study in rural Tanzania.

BACKGROUND: Current World Health Organization (WHO) guidelines recommend annual mass drug administration using praziquantel in areas with high schistosome endemicity. Yet little is known about incidence and reinfection rates after treatment in women with frequent exposure to schistosomes. We sought to quantify response to anti-schistosome treatment and incident S. mansoni infections in a cohort of rural women living in a schistosome-endemic area of northwest Tanzania. METHODS AND PRINCIPAL FINDINGS: We enrolled women with and without S. mansoni infection into a 12-month longitudinal cohort. Every 3 months, women were tested for schistosome infection using microscopic examinations for ova on filtered urine, Kato Katz slides, and serum Circulating Anodic Antigen (CAA). Those with schistosome infection received treatment with praziquantel 40 mg/kg according to the standard of care. We studied 35 women who were S. mansoni positive by stool microscopy and 46 women without schistosome infection who returned for at least one follow-up. Of the women who were initially infected, 14 (40%) were schistosome-positive at a follow-up visit. Four women developed incident infections, for a cumulative incidence of 8.7% and incidence rate of 0.99 per 100 person-months throughout the year among initially uninfected women. Only 3 women were egg-positive at any follow-up. Women with persistent, recurrent, or incident infection during the study period were significantly younger (p = 0.032) and had fewer children than women who remained uninfected or those who cleared the infection and did not experience recurrence (p = 0.003). Having fewer children remained significant after controlling for age (p = 0.023). There was no difference in initial intensity of infection by CAA or stool egg count, HIV status, or socioeconomic status. Although most water contact behaviors were comparable between the two groups, women with recurrent or incident schistosome infections were significantly more likely to have recently swum in the lake (p = 0.023). CONCLUSIONS: Our data suggests that annual praziquantel treatment reduces intensity of schistosome infections but is insufficient in providing stable parasite eradication in over a third of women in endemic communities. Furthermore, microscopy lacks adequate sensitivity to evaluate efficacy of treatment in this population. Our work demonstrates that further investigation into treatment efficacy and reinfection rates is warranted and suggests that increased frequency of praziquantel treatment is needed to improve cure rates in high-risk populations.
