Stigma of infidelity associated with condom use explains low rates of condom uptake: qualitative data from Uganda and Tanzania.

Despite widespread messaging supporting male (external) condom use to prevent HIV in endemic settings, utilization of condoms is low across sub-Saharan Africa. A thorough understanding of barriers to condom use as a form of HIV prevention is necessary to reduce HIV transmission. Here, we present qualitative data from rural eastern Africa to explain low utilization of condoms among heterosexual adults. Focus groups and interviews were conducted in Tanzania and Uganda between 2016 and 2019. A content analysis approach was used to identify attitudes about condoms and factors related to use/non-use. We found that strategies such as abstinence and being faithful to one's partner are perceived as ideal but rarely achievable methods of HIV prevention. Condoms are used in the setting of "failure" to abstain or be faithful and are therefore stigmatized as markers of infidelity. As such, use within cohabiting and long-term relationships is low. Our data suggest that negative perceptions of condoms may stem from persistent effects of the formerly applied "ABC" HIV prevention approach, a public health messaging strategy that described A-abstinence, B-be faithful, and C-use a condom as tiered prevention tools. Condom uptake could increase if HIV prevention messaging acknowledges existing stigma and reframes condom use for proactive health prevention. These studies were approved by Weill Cornell Medicine (Protocols 1803019105 and 1604017171), Mbarara University of Science and Technology (Protocol 16/0117), Uganda National Council of Science and Technology (Protocol SS-4338), and the Tanzania National Institute for Medical Research (Protocol NIMR/HQ/R.8c/Vol.I/1330).

Condoms are used to prevent HIV infection. Even though public health organizations have encouraged people to use condoms, many people in sub-Saharan Africa do not, especially in sexual encounters with someone that they are living with or married to. In this study, we wanted to understand the reasons that people were not using condoms. Between 2016 and 2019, we spoke with individuals in Uganda in one-on-one interviews about HIV prevention and testing and with focus groups in Tanzania about family planning. We analyzed transcripts of these conversations to find common themes about people's impressions of condom use. We learned that many of our participants believed that abstaining from sex and being faithful were the best ways to prevent HIV infection, but that they were not realistic strategies in the long term. Condoms were thought of as a useful tool for prevention when you "fail" at abstinence and monogamy. They were linked with being unfaithful, so people did not feel comfortable suggesting their use in committed relationships. These findings show that the "ABC" strategy for HIV prevention education may be continuing to make people think negatively about condom use. This strategy presented a tiered approach to HIV prevention, telling people it was best to (A) abstain, (B) be faithful to one's partners, and (C) use a condom. In order to increase engagement with HIV prevention, public health messages need to acknowledge the negative associations between condoms and infidelity.

How gender and religion impact uptake of family planning: results from a qualitative study in Northwestern Tanzania.

BACKGROUND: Women in Tanzania report a high unmet need for both information about and access to family planning. Prior studies have demonstrated the complex and variable relationship between religious faith and beliefs about family planning in sub-Saharan Africa. We hypothesized that a major reason for the poor uptake of family planning in Tanzania is that women and their partners are uncertain about whether pregnancy prevention is compatible with their religious beliefs. METHODS: Twenty-four focus group discussions with 206 participants were conducted in Mwanza, Tanzania between 2016 and 2017: six groups were conducted among Christian men, six among Christian women, six among Muslim men, and six among Muslim women. Among Christians, 98% were Protestants. Focus groups were also divided by gender and religion to facilitate discussion about gender-specific and religion-specific factors influencing family planning utilization. Qualitative data were analyzed using a thematic, phenomenological approach. RESULTS: We identify two important themes regarding the intersections of religion and family planning practices. First, we report that dynamics of family planning are experienced differently based on gender, and that male authority conflicts with female embodied knowledge, leading to negotiation or covert contraceptive use. Second, religious acceptability of family planning methods is of central importance, though participants differed in their interpretations of their religion's stance on this question. Most who found family planning incompatible with their faith affirmed their responsibility to give birth to as many children as God would give them. Others found family planning to be acceptable given their moral responsibility to care for and protect their children by limiting the family size. CONCLUSIONS: Both religious tradition and gender dynamics strongly influence the uptake of family planning, with a wide range of interpretations of religious traditions affecting the perceived acceptability of family planning. Regardless of gender or religious affiliation, participants were unified by a desire to live according to religious tradition. Future efforts to improve uptake of family planning are likely to have maximal impact if they are tailored to inform, involve, and empower male heads of households, and to address questions of religious acceptability.

Clinical and Demographic Factors Associated With Kaposi Sarcoma-Associated Herpesvirus Shedding in Saliva or Cervical Secretions in a Cohort of Tanzanian Women.

Background: Reasons for the high prevalence of Kaposi sarcoma-associated herpesvirus (KSHV) in sub-Saharan Africa, and risk factors leading to viral reactivation and shedding, remain largely undefined. Preliminary studies have suggested that schistosome infection, which has been associated with impaired viral control, is associated with KSHV. In this study we sought to determine the relationship between active Schistosoma mansoni or Schistosoma haematobium infection and KSHV shedding. Methods: We quantified KSHV DNA in saliva and cervical swabs from 2 cohorts of women living in northwestern Tanzanian communities endemic for S mansoni or S haematobium by real-time polymerase chain reaction. χ2 and Fisher exact tests were used to determine differences in clinical and demographic factors between those who were and were not shedding KSHV. Results: Among 139 total women, 44.6% were KSHV seropositive. Six percent of those with S mansoni and 17.1% of those with S haematobium were actively shedding KSHV in saliva and none in cervical samples. Women from the S mansoni cohort who were shedding virus reported infertility more frequently (80% vs 19.5%, P = .009). There was no difference in frequency of KSHV salivary shedding between schistosome-infected and -uninfected women. Conclusions: In an area with high KSHV seroprevalence and endemic schistosome infections, we provide the first report with data demonstrating no association between schistosome infection and salivary or cervical herpesvirus shedding. KSHV salivary shedding was associated with infertility, a known effect of another herpesvirus, human herpesvirus 6.

Effects of Schistosoma mansoni and praziquantel treatment on the lower gastrointestinal mucosa: A cohort study in Tanzania.

Schistosomes infect over 200 million people worldwide, but few studies have characterized the effects of Schistosoma mansoni infection and effective treatment on the lower gastrointestinal mucosa. In this prospective cohort study, we compared the clinical findings on sigmoidoscopy and laboratory measures in Tanzanian adults with and without S. mansoni infection at baseline and 6 months after praziquantel treatment. Grading of the endoscopic findings was done using the Mayo Scoring System for Assessment of Ulcerative Colitis Activity. Schistosome infection was confirmed by stool microscopy and serum circulating anodic antigen (CAA). Baseline comparisons were performed in Stata using Fisher's exact and Wilcoxon rank-sum tests, and pre- and post-treatment comparisons using Wilcoxon matched-pairs signed-rank and McNemar's tests. We investigated the clinical characteristics of 48 individuals: 32 with and 16 without S. mansoni infection. Infected individuals had greater severity of sigmoid and rectal mucosal abnormalities and higher Mayo scores and serum eosinophils (all p < 0.05) than uninfected individuals at initial evaluation. At 6 months, 28 individuals completed repeat blood tests and sigmoidoscopy. Of these, 14 cleared their baseline infection (n = 7) or experienced a greater than 7-fold decrease in serum CAA (n = 7). Follow-up sigmoidoscopies revealed some improvements in sigmoid and rectal mucosal findings, although Mayo scores were not significantly lower. Both the median erythrocyte sedimentation rates (32.5→12.5 mm/hr) and percent of eosinophils (7.1→3.1%) decreased in this group from baseline to follow-up. S. mansoni infection was associated with mild-to-moderate lower gastrointestinal mucosal abnormalities that were grossly visible during sigmoidoscopy, and these improved partially 6 months after effective treatment with praziquantel. Additional studies, of longer duration and focused on both clinical and mucosal immunologic effects of S. mansoni, could provide additional insight.

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.

Health providers' perspectives on contraceptive use in rural Northwest Tanzania: A qualitative study.

Objectives: In Tanzania, contraceptive use is limited, particularly in rural communities and even among women who would like to delay childbearing. This paper aims to present health providers' perspectives on populations seeking contraception and barriers that could be addressed to increase access to and uptake of contraception, given their interface with large portions of their communities. Study Design: We conducted 18 in-depth interviews with providers stationed at health dispensaries in six rural villages in northwest Tanzania. Two investigators independently coded interviews using a stepwise process to achieve consensus on prevalent topics. Results: Three topics emerged from our analysis: (1) nature of clients seeking contraception; (2) barriers to uptake of contraception; and (3) the role of secrecy in obtaining and using contraception. Health providers reported that married women with children were the most frequent users of contraception, alongside some single women, men, sex workers, and students. Barriers to contraception included lack of supplies and trained staff, misconceptions and fears, stigma, and unsupportive partners. Providers observed that contraception was often used secretly. They reported surreptitious visits and described clients' preferential use of discreet methods. Providers respected and supported clients' desires to keep visits confidential. Conclusion: Our data suggest maintaining high stocks of discreet contraceptive methods and deploying more trained staff to dispensaries could increase availability and access to contraceptives. At the community level, more education campaigns are warranted to address barriers, especially those related to stigma. Implications: Our work highlights the need for additional contraceptive methods that are easy to administer and discreet for women who must maintain secrecy. Future studies of the effectiveness of interventions and new contraceptives should obtain healthcare providers' perspectives, as they can provide important insights to service provision.

Schistosoma mansoni Infection Is Associated With Increased Monocytes and Fewer Natural Killer T Cells in the Female Genital Tract.

Schistosoma mansoni infection may impair genital mucosal antiviral immunity, but immune cell populations have not been well characterized. We characterized mononuclear cells from cervical brushings of women with and without S mansoni infection. We observed lower frequencies of natural killer T cells and higher frequencies of CD14+ monocytes in infected women.

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.

Design and pilot testing of a church-based intervention to address interpersonal and intrapersonal barriers to uptake of family planning in rural Tanzania: a qualitative implementation study.

BACKGROUND: Use of family planning (FP) saves the lives of mothers and children, and contributes to better economic outcomes for households and empowerment for women. In Tanzania, the overall unmet need for FP is high. This study aimed: (1) to use focus group data to construct a theoretical framework to understand the multidimensional factors impacting the decision to use FP in rural Tanzania; (2) to design and pilot-test an educational seminar, informed by this framework, to promote uptake of FP; and (3) to assess acceptability and further refine the educational seminar based on focus group data collected 3 months after the education was provided. METHODS: We performed a thematic analysis of 10 focus group discussions about social and religious aspects of FP from predominantly Protestant church attenders prior to any intervention, and afterwards from six groups of church leaders who had attended the educational seminar. RESULTS: Key interpersonal influences included lack of support from husband/partner, family members, neighbours and church communities. Major intrapersonal factors impeding FP use were lack of medical knowledge and information, misconceptions, and perceived incompatibility of FP and Christian faith. Post-seminar, leaders reported renewed intrapersonal perspectives on FP and reported teaching these perspectives to community members. CONCLUSIONS: Addressing intrapersonal barriers to FP use for leaders led them to subsequently address both intrapersonal and interpersonal barriers in their church communities. This occurred primarily by increasing knowledge and support for FP in men, family members, neighbours and church communities.

Preferences for family planning education among men and women in rural, highly religious Tanzanian communities: a discrete choice experiment.

Unmet need for family planning (FP) remains prevalent worldwide. In Tanzania, 21.7% of women desire to delay pregnancy, but do not use modern contraception despite its free availability at local clinics. Our prior data suggest that this is related to complex gender and religious dynamics in rural communities. To understand how education about FP could be improved, we developed a discrete choice experiment (DCE) to rank preferences of six attributes of FP education. Results were stratified by gender. Sixty-eight women and 76 men completed interview-assisted DCEs. Participants significantly preferred education by a clinician (men = 0.62, p < .001; women = 0.38, p < .001) and education in mixed-gender groups (men = 0.55, p < .001; women = 0.26, p < .001). Women also significantly preferred education by a religious leader (0.26, p = .012), in a clinic versus church, mosque, or community centre (0.31, p = .002), and by a female educator (0.12, p = .019). Men significantly preferred a male educator (0.17, p = .015), whom they had never met (0.25, p < .001), and educating married and unmarried people separately (0.22, p = .002). Qualitative data indicate women who had not previously used contraception preferred education led by a religious leader in a church or mosque. FP education tailored to these preferences may reach a broader audience, dispel misconceptions about FP and ultimately decrease unmet need.

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.
