BACKGROUND
Multiple sexual partnerships increase the risk of transmission of HIV and can be exacerbated by substance abuse. However, the association between psychoactive substance use and multiple sexual partnerships among young people in informal settlements of low-income countries is not well known. This study established the prevalence of multiple sexual partnerships and associated factors among young psychoactive-substance-users in informal settlements in Kampala, Uganda.
METHODS
This was a cross-sectional study involving 744 young (aged 18-24 years), sexually active, psychoactive substance-users selected from 12 of the 57 informal settlements of Kampala City. The prevalence of multiple sexual partnerships and their differential distribution by socio-demographic strata was established. Modified Poisson regression models were run in Stata 14 software to generate prevalence rate ratios for the factors associated with multiple sexual partnerships.
RESULTS
About 40.6% (37.9% of males and 50.0% of females) had engaged in multiple sexual partnerships in the last 30 days. Engaging in multiple sexual partnerships in the last 30 days was positively associated with being female (PR 1.29, 95% CI: 1.03-1.63); staying in the informal settlement for 6-10 years (PR 1.34, 95% CI: 1.02-1.75) and chewing khat in the last 30 days (PR 1.93, 95% CI: 1.10-3.40).
CONCLUSION
Multiple sexual partnerships are highly prevalent among young psychoactive-substance-users, irrespective of the socio-demographic strata. Being female, having lived in the informal settlement for 6-10 years, and chewing khat were significantly associated with having multiple sexual partners in the last 30 days. In tackling this high-risk sexual behaviour, it is recommended that risk-reduction interventions are considered for the different socio-demographic strata identified in this study, i.e. females, those who have lived in the informal settlement for about 6-10 years, and those who chew khat.
背景
多重性伴侣会增加 HIV 传播的风险，并且可能因滥用物质而加剧。然而，在低收入国家的非正规住区中，年轻人的心理活性物质使用与多重性伴侣之间的关联尚未得到充分了解。本研究旨在确定乌干达坎帕拉非正规住区中年轻心理活性物质使用者的多重性伴侣关系的流行率及其相关因素。
方法
这是一项横断面研究，涉及 744 名年龄在 18-24 岁之间、有过性行为的年轻心理活性物质使用者，他们是从坎帕拉市的 57 个非正规住区中选出的 12 个住区中的年轻人。确定了多重性伴侣关系的流行率及其在社会人口统计学阶层中的差异分布。在 Stata 14 软件中运行修正泊松回归模型，以生成与多重性伴侣关系相关的因素的流行率比。
结果
在过去 30 天内，约有 40.6%（男性为 37.9%，女性为 50.0%）的人发生了多重性伴侣关系。在过去 30 天内发生多重性伴侣关系与女性（PR 1.29，95%CI：1.03-1.63）、在非正规住区居住 6-10 年（PR 1.34，95%CI：1.02-1.75）和在过去 30 天内嚼阿拉伯茶（PR 1.93，95%CI：1.10-3.40）呈正相关。
结论
年轻心理活性物质使用者中多重性伴侣关系非常普遍，无论社会人口统计学阶层如何。女性、在非正规住区居住 6-10 年和嚼阿拉伯茶与过去 30 天内有多重性伴侣关系显著相关。在处理这种高风险性行为时，建议考虑针对本研究中确定的不同社会人口统计学阶层（即女性、在非正规住区居住约 6-10 年的人和嚼阿拉伯茶的人）实施减少风险的干预措施。
