Item Construct validity and internal consistency of the Patient Health Questionnaire-9 (PHQ-9) depression screening measure translated into two Ugandan languages(Psychiatry Research Communications, 2021) Miller, Amanda P.; Silva, Cristina Espinosa da; Ziegel, Leo; Stephen, Mugamba; Kyasanku, Emma; Bulamba, Robert M.; Wagman, Jennifer A.; Ekstromc, Anna Mia; Nalugoda, Fred; Kigozi, Grace; Nakigozi, Gertrude; Kagaayi, Joseph; Watya, Stephen; Kigozi, GodfreyIn Uganda, depression is a major public health issue. Psychometric assessment of translated depression measures is critical to public health planning to ensure proper screening, surveillance, and treatment of depression and related outcomes. We examined aspects of the validity and reliability of the Patient Health Questionnaire-9 (PHQ- 9) translated into Luganda and Runyoro among Ugandan adolescents and adults. Data from the ongoing AMBSO Population Health Surveillance study were analyzed from the Wakiso and Hoima districts in Uganda. Descriptive statistics were calculated for the overall sample and stratified by translated language. Construct validity was assessed for each translated scale using confirmatory factor analysis for ordinal data. The internal consistency of each translated scale was assessed using Cronbach's alpha, McDonald's omega total and omega hierarchical. Both the Luganda- and Runyoro-translated PHQ-9 had similar sample means (3.46 [SD ¼ 3.26] and 3.58 [SD ¼ 3.00], respectively), supported a single-factor structure, and demonstrated satisfactory internal consistency (Cronbach's alpha of 0.73 and 0.72, respectively). Our preliminary findings indicate that the Luganda and Runyoro translations of the PHQ-9 had satisfactory construct validity and internal consistency in our sample. Future studies should expand on this promising work by assessing additional psychometric characteristics of these translated measures in other communities in Uganda.Item Dynamics Of Pre-Exposure (PrEP) Eligibility due to Waxing and Waning of HIV Risk in Rakai, Uganda(JAIDS Journal of Acquired Immune Deficiency Syndromes, 2022) Ssempijja, Victor; Ssekubugu, Robert; Kigozi, Godfrey; Nakigozi, Gertrude; Kagaayi, Joseph; Nalugoda, Fred; Nantume, Betty; Batte, James; Kigozi, Grace; Nakawooya, Hadijja; Serwadda, David; Reynolds, Steven J.We conducted a retrospective population-based study to describe longitudinal patterns of prevalence, incidence, discontinuation, resumption, and durability of substantial HIV risk behaviors (SHR) for PrEP eligibility.The study was conducted among HIV-negative study participants aged 15-49 years that participated in survey rounds of the Rakai Community Cohort Study between August 2011 and June 2018. SHR was defined based on the Uganda national PrEP eligibility as either reporting sexual intercourse with >1 partner of unknown HIV status, non-marital sex without a condom or having transactional sex. Resumption of SHR meant resuming of SHR after stopping SHR, while persistence of SHR meant SHR on >1 consecutive visit. We used generalized estimation equations (GEE) with log-binomial regression models and robust variance to estimate survey-specific prevalence ratios (PR); GEE with modified Poisson regression models and robust variance to estimate incidence ratios for incidence, discontinuation, and resumption of PrEP eligibility.PrEP use should be tailored to the dynamic nature of PrEP eligibility. Preventive-effective adherence should be adopted for assessment of attrition in PrEP programs.Item High Rates of Pre-exposure Prophylaxis Eligibility and Associated HIV Incidence in a Population With a Generalized HIV Epidemic in Rakai, Uganda(Journal of Acquired Immune Deficiency Syndromes, 2022) Ssempijja, Victor; Nakigozi, Gertrude; Ssekubugu, Robert; Kagaayi, Joseph; Kigozi, Godfrey; Nalugoda, Fred; Nantume, Betty; Batte, James; Kigozi, Grace; Nakawooya, Hadijja; Serwadda, David; Cobelens, Frank; Reynolds, Steven J.The utility of using pre-exposure prophylaxis (PrEP) eligibility assessments to identify eligibility in general populations has not been well studied in sub-Saharan Africa. We used the Rakai Community Cohort Study to conduct a cross-sectional analysis to estimate PrEP eligibility and a cohort analysis to estimate HIV incidence associated with PrEP eligibility. Based on Uganda's national PrEP eligibility tool, we defined eligibility as reporting at least one of the following HIV risks in the past 12 months: sexual intercourse with more than one partner of unknown HIV status; nonmarital sex act without a condom; sex engagement in exchange for money, goods, or services; or experiencing genital ulcers. We used log-binomial and modified Poisson models to estimate prevalence ratios for PrEP eligibility and HIV incidence, respectively.Item HIV epidemiologic trends among occupational groups in Rakai, Uganda: A population-based longitudinal study, 1999–2016(Public Library of Science, 2024-02-20) Popoola, Victor O; Kagaayi, Joseph; Ssekasanvu, Joseph; Ssekubugu, Robert; Kigozi, Grace; Ndyanabo, Anthony; Nalugoda, Fred; Chang, Larry W; Lutalo, Tom; Tobian, Aaron A. R; Kabatesi, Donna; Alamo, Stella; Mills, Lisa A; Kigozi, Godfrey; Wawer, Maria J; Santelli, John; Gray, Ronald H; Reynolds, Steven J; Serwadda, David; Lessler, Justin; Grabowski, M. KateCertain occupations have been associated with heightened risk of HIV acquisition and spread in sub-Saharan Africa, including female bar and restaurant work and male transportation work. However, data on changes in population prevalence of HIV infection and HIV incidence within occupations following mass scale-up of African HIV treatment and prevention programs is very limited. We evaluated prospective data collected between 1999 and 2016 from the Rakai Community Cohort Study, a longitudinal population-based study of 15- to 49-year-old persons in Uganda. Adjusted prevalence risk ratios for overall, treated, and untreated, prevalent HIV infection, and incidence rate ratios for HIV incidence with 95% confidence intervals were estimated using Poisson regression to assess changes in HIV outcomes by occupation. Analyses were stratified by gender. There were 33,866 participants, including 19,113 (56%) women. Overall, HIV seroprevalence declined in most occupational subgroups among men, but increased or remained mostly stable among women. In contrast, prevalence of untreated HIV substantially declined between 1999 and 2016 in most occupations, irrespective of gender, including by 70% among men (12.3 to 4.2%; adjPRR = 0.30; 95%CI:0.23–0.41) and by 78% among women (14.7 to 4.0%; adjPRR = 0.22; 95%CI:0.18–0.27) working in agriculture, the most common self-reported primary occupation. Exceptions included men working in transportation. HIV incidence similarly declined in most occupations, but there were no reductions in incidence among female bar and restaurant workers, women working in local crafts, or men working in transportation. In summary, untreated HIV infection and HIV incidence have declined within most occupational groups in Uganda. However, women working in bars/restaurants and local crafts and men working in transportation continue to have a relatively high burden of untreated HIV and HIV incidence, and as such, should be considered priority populations for HIV programming.Item Intimate partner violence as a predictor of marital disruption in rural Rakai, Uganda: a longitudinal study(International journal of public health, 2016) Wagman, Jennifer A.; Charvat, Blake; Thoma, Marie E.; Ndyanabo, Anthony; Nalugoda, Fred; Ssekasanvu, Joseph; Kigozi, Grace; Serwadda, David; Kagaayi, Joseph; Wawer, Maria J.; Gray, Ronald H.We assessed the association between intimate partner violence (IPV) and union disruption (divorce or separation) in the rural Ugandan setting of Rakai District. We analyzed longitudinal data collected from April 1999 to June 2006, from 6834 women (15–49 years) living in 50 communities in Rakai. Participants were either married, traditionally married or in a consensual union during one or more surveys and completed at least one follow-up survey. The primary outcome was union disruption through divorce or separation from the primary sexual partner.Item Migration and risk of HIV acquisition in Rakai, Uganda: a population-based cohort study(The lancet HIV, 2018) Olawore, Oluwasolape; Tobian, Aaron A. R.; Kagaayi, Joseph; Bazaale, Jeremiah M.; Nantume, Betty; Kigozi, Grace; Nankinga, Justine; Nalugoda, Fred; Nakigozi, Gertrude; Kigozi, Godfrey; Gray, Ronald H.; Wawer, Maria J.; Ssekubugu, Robert; Santelli, John S.; Reynolds, Steven J.; Chang, Larry W.; Serwadda, David; Grabowski, Mary K.In sub-Saharan Africa, migrants typically have higher HIV prevalence than non-migrants; however, whether HIV acquisition typically precedes or follows migration is unknown. We aimed to investigate the risk of HIV after migration in Rakai District, Uganda. Methods In a prospective population-based cohort of HIV-negative participants aged 15–49 years in Rakai, Uganda, between April 6, 1999, and Jan 30, 2015, we assessed the association between migration and HIV acquisition. Individuals were classified as recent in-migrants (≤2 years in community), non-recent in-migrants (>2 years in community), or permanent residents with no migration history. The primary outcome was incident HIV infection. We used Poisson regression to estimate incidence rate ratios (IRRs) of HIV associated with residence status with adjustment for demographics, sexual behaviours, and time. Data were also stratified and analysed within three periods (1999–2004, 2005–11, and 2011–15) in relation to the introduction of combination HIV prevention (CHP; pre-CHP, early CHP, and late CHP). Findings Among 26 995 HIV-negative people who participated in the Rakai Community Cohort Study survey, 15 187 (56%) contributed one or more follow-up visits (89 292 person-years of follow-up) and were included in our final analysis. 4451 (29%) were ever in-migrants and 10 736 (71%) were permanent residents. 841 incident HIV events occurred, including 243 (29%) among in-migrants. HIV incidence per 100 person-years was significantly increased among recent in-migrants compared with permanent residents, for both women (1·92, 95% CI 1·52–2·43 vs 0·93, 0·84–1·04; IRR adjusted for demographics 1·75, 95% CI 1·33–2·33) and men (1·52, 0·99–2·33 vs 0·84, 0·74–0·94; 1·74, 1·12–2·71), but not among non-recent in-migrants (IRR adjusted for demographics 0·94, 95% CI 0·74–1·19 for women and 1·28, 0·94–1·74 for men). Between the pre-CHP and late-CHP periods, HIV incidence declined among permanent resident men (p<0·0001) and women (p=0·002) and non-recent in-migrant men (p=0·031), but was unchanged among non-recent in-migrant women (p=0·13) and recent in-migrants (men p=0·76; women p=0·84) Interpretation The first 2 years after migration are associated with increased risk of HIV acquisition. Prevention programmes focused on migrants are needed to reduce HIV incidence in sub-Saharan Africa.

In order to provide culturally appropriate mental health prevention and treatment approaches, it is necessary to understand how mental health is conceptualized in the population. Three focus group discussions (FGDs) and 31 in-depth interviews (IDIs) were conducted with men and women aged 14 to 62 years residing in rural, urban, and semi-urban low-income communities in central and western Uganda to explore perceptions and knowledge of mental health. Interpretive thematic analysis was undertaken; results were organized through the lens of the mental health literacy framework. Environmental and societal stressors were identified as primary underlying causes of poor mental health. While participants recognized symptoms of poor mental health, gaps in mental health literacy also emerged. Mental health resources are needed in this setting and additional qualitative work assessing knowledge and attitudes toward mental health care seeking behavior can inform the development of acceptable integrated services.Item Process evaluation of the SHARE intervention for preventing intimate partner violence and HIV infection in Rakai, Uganda(Evaluation and program planning, 2018) Wagman, Jennifer A.; Gray, Ronald H.; Nakyanjo, Neema; McClendond, Katherine A.; Bonneviea, Erika; Namatovu, Fredinah; Kigozi, Grace; Kagaayi, Joseph; Wawer, Maria J.; Nalugoda, FredThe Safe Homes And Respect for Everyone (SHARE) intervention introduced an intimate partner violence (IPV) prevention approach into Rakai Health Sciences Program, an established HIV research and service organization in Uganda. A trial found exposure to SHARE was associated with reductions in IPV and HIV incidence. This mixed methods process evaluation was conducted between August 2007 and December 2009, with people living in SHARE intervention clusters, to assess awareness about/participation in SHARE, motivators and barriers to involvement, and perceptions of how SHARE contributed to behavior change. Surveys were conducted with 1407 Rakai Community Cohort Study participants. Qualitative interviews were conducted with 20 key informants. Most (77%) were aware of SHARE, among whom 73% participated in intervention activities. Two-thirds of those who participated in SHARE felt it influenced behavior change related to IPV. While some felt confident to take part in new IPV-focused activities of a well-established program, others were suspicious of SHARE’s motivations, implying awareness raising is critical. Many activities appealed to the majority (e.g., community drama) while interest in some activities was limited to men (e.g., film shows), suggesting multiple intervention components is ideal for wide-reaching programming. The SHARE model offers a promising, acceptable approach for integrating IPV prevention into HIV and other established health programs in sub-Saharan Africa.Item Self-selection of Male Circumcision Clients and Behaviors following Circumcision in a Service Program in Rakai, Uganda(AIDS (London, England), 2016) Kagaayi, Joseph; Kong, Xiangrong; Kigozi, Godfrey; Ssekubugu, Robert; Kigozi, Grace; Nalugoda, Fred; Serwadda, David; Wawer, Maria J.; Gray, Ronald H.Sub-Saharan African countries have substantially scaled-up safe male circumcision (SMC) services. However, it is unclear whether services are reaching men most at risk of HIV and whether there is behavioral disinhibition after SMC. We compared characteristics of SMC acceptors and non-acceptors in Rakai, Uganda. Cohort design Through the Rakai Community Cohort Study, baseline characteristics of 587 non-Muslim men who subsequently accepted SMC were compared to those of 4,907 uncircumcised non-Muslim men. Behaviors after SMC were compared with those of men who remained uncircumcised. Poisson multivariable regression was used to estimate adjusted prevalence rate ratios (aPRR) of behaviors in circumcised versus uncircumcised men.Item Sexual satisfaction of women partners of circumcised men in a randomized trial of male circumcision in Rakai, Uganda(AIDS (London, England), 2016) Kigozi, Godfrey; Lukabwe, Ivan; Kagaayi, Joseph; Wawer, Maria J.; Nantume, Betty; Kigozi, Grace; Nalugoda, Fred; Kiwanuka, Noah; Wabwire-Mangen, Fred; Serwadda, David; Ridzon, Renee; Buwembo, Dennis; Nabukenya, Dorothy; Watya, Stephen; Lutalo, Tom; Nkale, James; Gray, Ronald H.To investigate the effect of adult medical male circumcision on female sexual satisfaction. We investigated self-reported sexual satisfaction among 455 women partners of men circumcised in a randomized trial of male circumcision for the prevention of human immunodeficiency virus in Rakai, Uganda. Women aged 15–49 years were interviewed about their sexual satisfaction before and after their partners were circumcised. We analyzed female-reported changes in sexual satisfaction using chi-square or Fisher’s exact tests.Item Survival of Infants Born to HIV-Positive Mothers, by Feeding Modality, in Rakai, Uganda(PLoS ONE, 2008) Kagaayi, Joseph; Gray, Ronald H.; Brahmbhatt, Heena; Kigozi, Godfrey; Nalugoda, Fred; Wabwire-Mangen, Fred; Serwadda, David; Sewankambo, Nelson; Ddungu, Veronica; Ssebagala, Darix; Sekasanvu, Joseph; Kigozi, Grace; Makumbi, Fredrick; Kiwanuka, Noah; Lutalo, Tom; Reynolds, Steven J.; Wawer, Maria J.Data comparing survival of formula-fed to breast-fed infants in programmatic settings are limited. We compared mortality and HIV-free of breast and formula-fed infants born to HIV-positive mothers in a program in rural, Rakai District Uganda. One hundred eighty two infants born to HIV-positive mothers were followed at one, six and twelve months postpartum. Mothers were given infant-feeding counseling and allowed to make informed choices as to whether to formula-feed or breast-feed. Eligible mothers and infants received antiretroviral therapy (ART) if indicated. Mothers and their newborns received prophylaxis for prevention of mother-to-child HIV transmission (pMTCT) if they were not receiving ART. Infant HIV infection was detected by PCR (Roche Amplicor 1.5) during the follow-up visits. Kaplan Meier time-to-event methods were used to compare mortality and HIV-free survival. The adjusted hazard ratio (Adjusted HR) of infant HIV-free survival was estimated by Cox regression. Seventy-five infants (41%) were formula-fed while 107 (59%) were breast-fed. Exclusive breast-feeding was practiced by only 25% of breast-feeding women at one month postpartum. The cumulative 12-month probability of infant mortality was 18% (95% CI = 11%–29%) among the formula-fed compared to 3% (95% CI = 1%–9%) among the breast-fed infants (unadjusted hazard ratio (HR) = 6.1(95% CI = 1.7–21.4, P-value,0.01). There were no statistically significant differentials in HIV-free survival by feeding choice (86% in the formula-fed compared to 96% in breast-fed group (Adjusted RH = 2.8[95%CI = 0.67–11.7, P-value = 0.16]
