Social networks and HIV treatment adherence among people with HIV initiating treatment in rural Uganda and peri-urban South Africa.

Timely initiation of and adherence to antiretroviral therapy (ART) is critical for improving HIV outcomes and reducing HIV transmissibility. Social networks, or the social relationships individuals have with each other, have been linked with positive health outcomes, but less is known about the extent to which social network composition and structure are associated with improved ART adherence among people living with HIV (PLWH). We conducted an ego-centric network study among 828 previously ART-naïve PLWH presenting for ART initiation at 11 clinics in Mbarara, Uganda (rural population) and Gugulethu, South Africa (peri-urban population). We collected social network data using name generator and name interpreter questions. ART adherence was monitored over 12 months using wireless monitors (Wisepill). Our primary outcome of interest was ART adherence during the 12-month follow-up period. We used generalized linear models to estimate the associations between network measures and ART adherence. PLWH at the Uganda site (compared with the South Africa site) were less isolated, had larger social networks, and had more social ties providing sufficient social support; they were also more likely to bridge different social groups whereby not all social ties were connected to each other. In Uganda, social isolation was associated with a 5.5 percentage point reduction in ART adherence (95% confidence interval [CI] -9.95 to -1.13; p = 0.014), while having more same gender social ties was associated with higher ART adherence (b = 0.13, 95% CI 0.02-0.25, p = 0.025). In South Africa, there was no association between social isolation and ART adherence, and having more friendship ties (vs. family ties) was associated with lower ART adherence (b = -2.20, 95% CI -3.56 to -0.84; p = 0.002). Identifying and supporting PLWH who are isolated may facilitate optimal adherence, but understanding how networks differentially affect ART adherence by country context is important.

Provision of DMPA-SC for self-administration in different practice settings during the COVID-19 pandemic: Data from providers across the United States.

OBJECTIVES: Depot medroxyprogesterone acetate-subcutaneous (DMPA-SC) can be prescribed through telemedicine and self-administered, but data about availability, particularly during the COVID-19 pandemic, are limited. This study assessed changes in the availability of DMPA-SC for self-administration during the pandemic. STUDY DESIGN: This study used survey data from a convenience sample of US providers engaged in contraceptive care and participating in a Continuing Medical Education-accredited contraceptive training (April 2020-April 2022; n = 849). Providers were recruited from across 503 clinics, including primary care and family planning clinics, public health departments, college and school-based health centers, independent abortion care clinics, and outpatient clinics in hospital settings. Measures included the availability of DMPA-SC for self-administration before and during the pandemic and the use of telemedicine. We used Poisson regression models and cluster-robust errors by clinic, adjusting for region, time of survey, and clinic size, to assess clinic availability of DMPA-SC for self-administration by practice setting. RESULTS: Compared to the prepandemic period (4%), the availability of DMPA-SC for self-administration increased significantly during the pandemic (14%) (adjusted prevalence ratios [aPR] 3.43, 95% CI [2.43-4.85]). During the pandemic, independent abortion clinics were more likely to offer DMPA-SC for self-administration compared to primary care clinics (aPR 2.44, 95% CI [1.10-5.41]). Clinics receiving Title X funds were also more likely to provide DMPA-SC for self-administration during the pandemic compared to other clinics (aPR 2.32, 95% CI [1.57-3.43]), and more likely to offer DMPA-SC for self-administration through telemedicine (aPR 2.35, 95% CI [1.52-3.63]). Compared to the early pandemic period (April-September 2022), telemedicine access to DMPA-SC for self-administration was highest during the later pandemic time period (October 2021-April 2022) (aPR 2.10, 95% CI [1.06-4.17]). CONCLUSIONS: The availability of DMPA-SC for self-administration significantly increased during the pandemic with differences by practice setting and Title X funding. However, overall method availability remains persistently low. IMPLICATIONS: Despite increased availability of DMPA-SC for self-administration among US contraceptive providers during the COVID-19 pandemic, there remains a need to train providers, educate patients, and remove barriers to ensure broader availability of this method across different practice settings.

Misperception of Norms About Intimate Partner Violence as a Driver of Personal IPV Attitudes and Perpetration: A Population-Based Study of Men in Rural Uganda.

Intimate partner violence (IPV) against women is a global public health problem. Conceptual frameworks suggest misperceived norms around IPV might drive perpetration of violence against women in southern and eastern Africa. We conducted a cross-sectional, population-based survey of all men residing in a rural parish in southwest Uganda, eliciting their endorsement of IPV in five hypothetical scenarios and their reported frequency of perpetration of violence against their wife/main partner. They also reported their perceptions about the extent to which most other men in their villages endorsed and/or perpetrated IPV, which we compared against the population data to measure the primary explanatory variable of interest: whether individuals misperceived norms around IPV. We fitted multivariable Poisson regression models specifying personal IPV endorsement and IPV perpetration as the outcomes. Overall, 765 men participated in the study (90% response rate): 182 (24%) personally endorsed IPV, and 78 of 456 partnered men (17%) reported perpetrating one or more acts of IPV at least once per month. Although most men neither endorsed nor reported perpetrating IPV, 342 (45%) men mistakenly thought that most other men in their villages endorsed IPV and 365 (48%) men mistakenly thought that most other men perpetrate IPV at least monthly. In multivariable regression models, men who misperceived most men to endorse IPV were more likely to endorse IPV themselves (adjusted relative risk [aRR] = 2.44; 95% CI [1.66, 3.59]; p < .001). Among partnered men, those who misperceived IPV perpetration to be normative were more likely to perpetrate IPV themselves (aRR = 4.38; [2.53, 7.59]; p < .001). Interventions to correct misperceived norms about IPV may be a promising method for reducing violence against women in rural Uganda.

Male circumcision uptake and misperceived norms about male circumcision: Cross-sectional, population-based study in rural Uganda.

Background: Over the past decade, 15 high-priority countries in eastern and southern Africa have promoted voluntary medical male circumcision for human immunodeficiency virus (HIV) and sexually transmitted infection (STI) prevention. The prevalence of male circumcision in Uganda nearly doubled from 26% in 2011 to 43% in 2016, but remains below the 2020 target level. Little is known about how common male circumcision is perceived to be, how accurate such perceptions are, and whether they are associated with men's own circumcision uptake. Methods: We conducted a cross-sectional study of all adult residents of eight villages in Rwampara District, southwestern Uganda in 2020-2022. We elicited their perceptions of the adult male circumcision prevalence within their village: >50% (most men), 10% to <50% (some), <10%, (few to none), or do not know. We compared their perceived norms to the aggregated prevalence of circumcision reported in these villages. We used a modified multivariable Poisson regression model to estimate the association between perceived norms and personal circumcision uptake among men. Results: We surveyed 1566 participants (91% response rate): 698 men and 868 women. Among the men, 167 (27%) reported being circumcised, including 167/444 (38%) men <50 years of age. Approximately one-fourth of the population (189 (27%) men and 177 (20%) women) believed that few to no men in their own village had been circumcised. In a multivariable regression model, men who underestimated the prevalence of male circumcision were less likely to be circumcised themselves (adjusted relative risk (aRR) = 0.51; 95% confidence interval (CI) = 0.37-0.83). Conclusions: In this population-based study in rural Uganda, one-fourth of men underestimated the prevalence of male circumcision. Men who underestimated the extent of circumcision uptake were themselves less likely to be circumcised. If the observed association is causal and underestimates within the population contribute to low uptake, then interventions correcting these misperceived norms could increase uptake of voluntary medical male circumcision.
