Abstract

Introduction

While extra-marital relations have been associated with increased risk for HIV infection in previous studies, extant literature on the prevalence and factors associated with these sexual relationships remains largely limited. We assessed the prevalence and factors associated with extra-spousal partnerships among currently married individuals.

Methods

This secondary analysis uses data from a large cross-sectional study conducted among married individuals aged 15-49 years in Rakai, Uganda. We used a generic definition of marriage to include all individuals who considered themselves as “married” irrespective of category. Extra-spousal sexual partnerships were defined as concurrent sexual relationships between a married individual and another person (of the opposite sex) with whom they were not currently married. We determined the prevalence of extra-spousal partnerships and used a modified Poisson regression model to assess factors independently associated (at P<0.05) with extra-spousal partnerships, after adjusting for potential confounders. We used STATA (version 14.0) for data analysis.

Results

Of 2,103 currently married individuals, 51.5% (n=1,084) were females; 66.1% (n=1,391) were in their first marriage ever, while 83.3% (n=1,751) had been married for five or more (5+) years. Thirteen per cent (n=282) reported extra-spousal partnerships; 4.5% (n=49) among females and 22.9% (n=233) among males. Being HIV-positive, being in the third or higher marital order marriage, engagement in housework (among women), and being male were significantly associated with engaging in extra-spousal partnerships. Being 35 years or older was protective against engaging in extra-spousal partnerships.

Conclusion

One in ten currently married individuals engaged in extra-spousal partnerships. Extra-spousal partnerships were more common among men, individuals living with HIV, those with a higher number of previous marriages, and women engaged in housework than their counterparts.

Recommendations

Targeted HIV prevention interventions, including those that focus on men and previously married individuals, are urgently needed to protect married individuals from the risk of extra-spousal partnerships.

Arnold Tigaiza is a PhD Fellow at Makerere University School of Public Health. He holds a Bachelor’s degree in Environmental Health Sciences and a Master’s degree in Public Health. His broader academic interests include migration, health systems, and social determinants of health in low-resource settings. He is passionate about using evidence to inform policy and improve service delivery for marginalized communities. His PhD research focuses on the mental health impacts of climate change-induced youth migration in secondary cities of Uganda. He is particularly interested in understanding the differences or similarities in how common depression is among youth who migrate to cities as a result of climate shocks, youths who do not migrate despite climate shocks, and youths who are born and raised in the cities where the migrant youth move to. He is also studying how ecological stressors and mobility patterns affect depression and help-seeking behaviors among young people.
