Brief Report: Age-Disparate Relationships and HIV Prevalence Among Never Married Women in Rakai, Uganda.

ABSTRACT: BACKGROUND:Age-disparate relationships are associated with increased HIV prevalence. We determined whether the frequency of age-disparate relationships in never married women changed over time and whether they are associated with HIV prevalence in Rakai, Uganda. METHODS:A total of 10,061 never married women, aged 15-49 years, in the Rakai Community Cohort Study provided information on the age of their male sexual partners from 1997 to 2013. Logistic regression was used to assess trends in age-disparate relationships (?5 years) between never married women and their male partners. Log-binomial regression was used to estimate adjusted prevalence ratios (adjPR) of HIV prevalence associated with age-disparate relationships. RESULTS:Two thousand nine hundred ninety-nine women (30%) had a male partner ?5 years older, which remained stable over time. The prevalence of HIV among women in age-disparate relationships was 14%, 10% for women in relationships with men 0-4 years older (adjPR 1.36, 95% confidence interval: 1.22 to 1.53) not controlling women's age; however, after age adjustment, the impact of age-disparate relationships on HIV prevalence was attenuated. Age-disparate relationships were associated with increased HIV prevalence among women aged 15-17 years (adjPR 1.83, 95% confidence interval: 1.10 to 3.17), but not in other age groups. CONCLUSIONS:The frequency of age-disparate relationships among never married women was unchanged over a 15-year period in Rakai, Uganda. Age-disparate relationships were associated with increased HIV prevalence among adolescents aged 15-17 years, but not older women.

Project description:BackgroundUptake of couples' HIV counseling and testing (couples' HCT) services remains largely low in most settings. We report the effect of a demand-creation intervention trial on couples' HCT uptake among married or cohabiting individuals who had never received couples' HCT.MethodsThis was a cluster-randomized intervention trial implemented in three study regions with differing HIV prevalence levels (range: 9-43 %) in Rakai district, southwestern Uganda, between February and September 2014. We randomly assigned six clusters (1:1) to receive the intervention or serve as the comparison arm using computer-generated random numbers. In the intervention clusters, individuals attended small group, couple and male-focused interactive sessions, reinforced with testimonies from 'expert couples', and received invitation coupons to test together with their partners at designated health facilities. In the comparison clusters, participants attended general adult health education sessions but received no invitation coupons. The primary outcome was couples' HCT uptake, measured 12 months post-baseline. Baseline data were collected between November 2013 and February 2014 while follow-up data were collected between March and April 2015. We conducted intention-to-treat analysis using a mixed effects Poisson regression model to assess for differences in couples' HCT uptake between the intervention and comparison clusters. Data analysis was conducted using STATA statistical software, version 14.1.ResultsOf 2135 married or cohabiting individuals interviewed at baseline, 42 % (n = 846) had ever received couples' HCT. Of those who had never received couples' HCT (n = 1,174), 697 were interviewed in the intervention clusters while 477 were interviewed in the comparison clusters. 73.6 % (n = 513) of those interviewed in the intervention and 82.6 % (n = 394) of those interviewed in the comparison cluster were interviewed at follow-up. Of those interviewed, 72.3 % (n = 371) in the intervention and 65.2 % (n = 257) in the comparison clusters received HCT. Couples' HCT uptake was higher in the intervention than in the comparison clusters (20.3 % versus 13.7 %; adjusted prevalence ratio (aPR) = 1.43, 95 % CI: 1.02, 2.01, P = 0.04).ConclusionOur findings show that a small group, couple and male-focused, demand-creation intervention reinforced with testimonies from 'expert couples', improved uptake of couples' HCT in this rural setting.Trial registrationClinicalTrials.gov, NCT02492061 .

Project description:HIV and malaria exert co-pathogenic effects. Malaria surveillance data are necessary for public health strategies to reduce the burden of disease in high HIV prevalence settings.This was a longitudinal cohort study to assess the burden of malaria in rural Rakai, Uganda. Households were visited monthly for 1 year to identify confirmed clinical malaria (CCM), or parasitaemia with temperature >37.5 °C, and asymptomatic parasitaemia (AP). Interviews of the adult or child's caregiver and clinical and laboratory assessments were conducted. Rapid diagnostic testing for malaria and anaemia was performed if participants were febrile and anti-malarial treatment given per Uganda Ministry of Health 2010 guidelines. Blood was drawn at every household visit to assess for parasitaemia, and blood smears were assessed at the Rakai Health Science Programme laboratory.A total of 1640 participants were enrolled, including 975 children aged 6 months up to 10 years, 393 adult caregivers, and 272 adolescent/adult household members from 393 randomly selected households in two representative communities. 1459 (89 %) participants completed all study visits. CCM was identified in 304 (19 %) participants, with the highest incidence rate for CCM of 0.38 per person-year (ppy) identified in children <5 years, and rates decreased with age; the rates were 0.27, 0.16, and 0.09 ppy for ages 5-<10 years, 10-<18 years, and adults 18+ years, respectively. AP was identified in 943 (57 %) participants; the incidence rate was 1.99 ppy for <5 years, 2.72 ppy for 5-<10 years, 2.55 ppy for 10-<18 years, and 0.86 ppy among adults, with 92 % of cases being attributed to Plasmodium falciparum by smear. 994 (61 %) individuals had at least one positive smear; 342 (21 %) had one positive result, 203 (12 %) had two, 115 (7 %) had three, and 334 (21 %) had >3 positive smears during follow-up. Seasonal rates generally followed the rains and peaked during July, then decreased through November before increasing again.Plasmodium falciparum infection remains high in rural Uganda. Increased malaria control interventions should be prioritized. Trial registration Clinicaltrials.gov identifier NCT01265407.
