Item AIDS Care: Psychological and Socio-medical Aspects of AIDS/HIV(AIDS Care, 2011) Nakigozi, Gertrude; Makumbi, Fredrick; Reynolds, Steven; Galiwango, Ronald; Kagaayi, Joseph; Nalugoda, Fred; Ssettuba, Absalom; Sekasanvu, Joseph; Musuuza, Jackson; Serwada, David; Gray, Ron; Wawer, MariaImproved understanding of HIV-related health-seeking behavior at a population level is important in informing the design of more effective HIV prevention and care strategies. We assessed the frequency and determinants of failure to seek free HIV care in Rakai, Uganda. HIV-positive participants in a community cohort who accepted VCT were referred for free HIV care (cotrimoxazole prophylaxis, CD4 monitoring, treatment of opportunistic infections, and, when indicated, antiretroviral therapy). We estimated proportion and adjusted Prevalence Risk Ratios (adj. PRR) of non-enrollment into care six months after receipt of VCT using log-binomial regression. About 1145 HIV-positive participants in the Rakai Community Cohort Study accepted VCT and were referred for care. However, 31.5% (361/1145) did not enroll into HIV care six months after referral. Non-enrollment was significantly higher among men (38%) compared to women (29%, p 0.005). Other factors associated with nonenrollment included: younger age (15 24 years, adj. PRR 2.22; 95% CI: 1.64, 3.00), living alone (adj. PRR 2.22; 95% CI: 1.57, 3.15); or in households with 1 2 co-residents (adj. PRR 1.63; 95% CI: 1.31, 2.03) compared to three or more co-residents, or a CD4 count 250 cells/ul (adj. PRR 1.81; 95% CI: 1.38, 2.46). Median (IQR) CD4 count was lower among enrolled 388 cells/ul (IQR: 211,589) compared to those not enrolled 509 cells/ul (IQR: 321,754).About one-third of HIV-positive persons failed to utilize community-based free services. Non-use of services was greatest among men, the young, persons with higher CD4 counts and the more socially isolated, suggesting a need for targeted strategies to enhance service uptakeItem Desire for female sterilization among women wishing to limit births in rural Rakai, Uganda(Contraception, 2015) Lutalo, Tom; Gray, Ron; Sanyukta, Mathur,; Wawer, Maria; Guwatudde, David; Santelli, John; Nalugoda, Fred; Makumbi, Fredrick: Uganda has an unmet need for family planning of 34% and a total fertility rate of 6.2. We assessed the desire for female sterilization among sexually active women who wanted to stop childbearing in rural Rakai district, Uganda. Study design: 7,192 sexually active women enrolled in a community cohort between 2002 and 2008 were asked about fertility intentions. Those stating that they did not want another child (limiters) were asked whether they would be willing to accept female sterilization, if available. Trends in desire for sterilization were determined by Chi-square test for trend, and Modified Poisson regression was used to estimate prevalence rate ratios (PRR) and 95% confidence intervals of the associations between desire for sterilization and socio-demographic characteristics and HIV status. Results: From 2002 to 2008, the proportion of limiters dropped (47.2% to 43.7%; p<0.01). Use of pills and injectables among limiters significantly increased, 38.9% to 50.3% (p<0.0001), while use of IUDs and implants declined from 3.3% to 1.7% (p<0.001). The desire for sterilization significantly increased from 54.2% to 63.1% (p<0.0001), and this was consistently higher among the HIV-positive (63.6% to 70.9%, p<0.01) than HIV-negative women (53.3% to 61.2%, p<0.0001). Factors significantly associated with the desire for sterilization included higher number of living children (>=3), being HIV-infected and having received HIV counseling and testing. Conclusion: There is latent and growing desire for sterilization in this population. Our findings suggest a need to increase permanent contraception services for women who want to limit childbearing in this setting.Item Experiences of Sexual Coercion Among Adolescent Women: Qualitative Findings From Rakai District, Uganda(Journal of interpersonal violence, 2008) Wagman, Jennifer; Baumgartner, Joy Noel; Geary, Cindy Waszak; Nakyanjo, Neema; Ddaaki, William George; Serwadda, David; Gray, Ron; Nalugoda, Fred Kakaire; Wawer, Maria J.Limited data from low-income countries are available on the continuum of coercive experiences, the contexts in which they occur, and how adolescent women perceive and respond to coercion. This article presents results from focus group discussions and in-depth interviews with pregnant and never pregnant sexually active female adolescents, aged 15 to 17, residing in Rakai District, Uganda, to examine sexual coercion, its context, and the links between coercion and adolescent reproductive health outcomes, including early sexual debut and pregnancy. Informants described multiple forms of sexual coercion, including coerced or forced intercourse, unwanted sexual touching, verbal harassment, and transactional sex. Sexual coercion was perceived to be a normal part of intimate relationships; in particular, informants felt that a woman’s lack of decision-making authority, including choices on sexual encounters, was implicit to marriage. This information may help violence prevention programs develop a range of strategies for addressing sexual coercion among adolescents.Item Failure of immunologic criteria to appropriately identify antiretroviral treatment failure in Uganda(AIDS, 2009) Reynolds, Steven J.; Nakigozi, Gertrude; Newell, Kevin; Ndyanabo, Anthony; Galiwongo, Ronald; Iga, Boaz; Quinn, Thomas C.; Gray, Ron; Wawer, Maria; Serwadda, DavidMost antiretroviral treatment program in resource-limited settings use immunologic or clinical monitoring to measure response to therapy and to decide when to change to a second line regimen. Our objective was to evaluate immunologic failure criteria against gold standard virologic monitoring. Design—Observation cohort Methods—Participants enrolled in an antiretroviral treatment program in rural Uganda who had at least 6 months of follow-up were included in this analysis. Immunologic monitoring was performed by CD4 cell counts every 3 months during the first year, and every 6 months thereafter. HIV-1 viral loads were performed every 6 months. Results—1133 participants enrolled in the Rakai Health Sciences Program antiretroviral treatment program between June 2004 and September 2007 were followed for up to 44.4 months (median follow-up 20.2 months; IQR 12.4–29.5 months). WHO immunologic failure criteria were reached by 125 (11.0%) participants. A virologic failure endpoint defined as HIV-1 viral load (VL) >400 copies/ml on two measurements was reached by 112 participants (9.9%). Only 26 participants (2.3%) experiencedItem Failure of immunologic criteria to appropriately identify antiretroviral treatment failure in Uganda(AIDS (London, England), 2009-03) Reynolds, Steven J.; Nakigozi, Gertrude; Newell, Kevin; Ndyanabo, Anthony; Ronald, Galiwongo; Iga, Boaz; . Quinn, Thomas C; Gray, Ron; Wawer, Maria; Serwadda, DavidObjective—Most antiretroviral treatment program in resource-limited settings use immunologic or clinical monitoring to measure response to therapy and to decide when to change to a second line regimen. Our objective was to evaluate immunologic failure criteria against gold standard virologic monitoring. Design—Observation cohort Methods—Participants enrolled in an antiretroviral treatment program in rural Uganda who had at least 6 months of follow-up were included in this analysis. Immunologic monitoring was performed by CD4 cell counts every 3 months during the first year, and every 6 months thereafter. HIV-1 viral loads were performed every 6 months. Results—1133 participants enrolled in the Rakai Health Sciences Program antiretroviral treatment program between June 2004 and September 2007 were followed for up to 44.4 months (median follow-up 20.2 months; IQR 12.4–29.5 months). WHO immunologic failure criteria were reached by 125 (11.0%) participants. A virologic failure endpoint defined as HIV-1 viral load (VL) >400 copies/ml on two measurements was reached by 112 participants (9.9%). Only 26 participants (2.3%) experienced both an immunologic and virologic failure endpoint (2 VL>400 copies/ml) during follow-up. Conclusions—Immunologic failure criteria performed poorly in our setting and would have resulted in a substantial proportion of participants with suppressed HIV-1 VL being switched unnecessarily. These criteria also lacked sensitivity to identify participants failing virologically. Periodic viral load measurements may be a better marker for treatment failure in our settingItem A Public Health Approach to Intimate Partner Violence Prevention in Uganda: The SHARE Project(Violence against women, 2012) Wagman, Jennifer A.; Namatovu, Fredinah; Nalugoda, Fred; Kiwanuka, Deus; Nakigozi, Gertrude; Gray, Ron; Wawer, Maria J.; Serwadda, DavidResearch from Rakai, Uganda, suggests intimate partner violence (IPV) is common and attitudes condoning it are widespread. We used a public health approach to develop and implement an evidence-based IPV prevention intervention named the Safe Homes and Respect for Everyone (SHARE) Project. SHARE was designed on the Transtheoretical Model of behavior change and adapted IPV prevention strategies from Raising Voices and Stepping Stones. SHARE was implemented in four regions of Rakai. This article describes the design and implementation of SHARE, provides details on strategies and activities used, discusses challenges and lessons learned, and provides recommendations for other violence prevention programmers.Item Trends in HIV acquisition, risk factors and prevention policies among youth in Uganda, 1999-2011(AIDS, 2015) Santellia, John S.; Edelsteina, Zoe R.; Weia, Ying; Mathura, Sanyukta; Songa, Xiaoyu; Schuylera, Ashley; Nalugoda, Fred; Lutalo, Tom; Gray, Ron; Wawerd, Maria; Serwadda, DavidThe objective of this study is to understand how trends in HIV acquisition among youth can be influenced by change in HIV risk factors, social factors and prevention and treatment programmes. Design: Trends in HIV incidence (per 1000 person-years), by sex and age group, were estimated using data from youth (15–24 years: n = 22 164) in the Rakai Community Cohort Study. Trends in HIV incidence were compared with trends in previously identified HIV risk factors, social factors and programmes. Methods: Poisson and linear regression were used to test for statistical significance and decomposition was used to calculate attribution of risk factors to HIV incidence. Results: Substantial declines between 1999 and 2011 occurred in sexual experience, multiple partners and sexual concurrency among adolescents and young adults. HIV acquisition declined substantially (86%, P = 0.006) among adolescent women (15–19 years) but not among men or young adult women. Changes in HIV incidence and risk behaviours coincided with increases in school enrolment, decline in adolescent marriage, availability of antiretroviral therapy (ART) and increases in male medical circumcision (MMC). Much of the decline in HIV incidence among adolescent women (71%) was attributable to reduced sexual experience;the decline in sexual experience was primarily attributable to increasing levels of school enrollment. Conclusion: Dramatic decreases in HIV incidence occurred among adolescent women in Rakai. Changes in school enrollment and sexual experience were primarily responsible for declining HIV acquisition over time among adolescent women. Given limited improvement among young men and young adult women, the need for effective HIV prevention for young people remains critical.Item Unfulfilled need for contraception among women with unmet need but with the intention to use contraception in Rakai, Uganda: a longitudinal study(BMC women's health, 2018) Lutalo, Tom; Gray, Ron; Santelli, John; Guwatudde, David; Brahmbhatt, Heena; Mathur, Sanyukta; Serwadda, David; Nalugoda, Fred; Makumbi, FredrickLongitudinal data from a rural Ugandan cohort was used to estimate rates of unfulfilled need for contraception, defined as having unmet need and intent to use contraception at baseline but having an unintended pregnancy or with persistent unmet need for contraception at follow up. Methods: Between 2002 and 2009 (5 survey rounds), a total of 2610 sexually active non-pregnant women with unmet need for contraception at the start of an inter-survey period were asked whether they intended to use any method of contraception until they desired a child. Modified Poisson multivariate regression was used to estimate unadjusted and adjusted prevalence ratios (PR) and 95% CI of unfulfilled need for contraception. Results: The proportion of women with unmet need at the start of an interval who intended to use contraception significantly increased from 61 to 69.1% (p < 0.05). However the majority of women who said they intended to use contraception had unfulfilled need for contraception at the subsequent survey (64.8 to 56.8%). In the adjusted analysis, significant predictors of unfulfilled need for contraception included age 40–49 years (PR = 1.34; 95% CI 1. 04–1.74) and those with unknown HIV status (PR = 1.16; 95% CI 1.06–1.26). Conclusions: There is a significant discrepancy between women’s intent to use contraception (> 60%) and subsequent initiation of use (< 30%) with many having unintended pregnancies which might explain the persistent high fertility in Uganda. Future research needs to address unfulfilled need for contraception among women at risk of unintended pregnancies.
