Association between substance use and concurrent sexual relationships among urban slum dwellers in Nairobi, Kenya

Predictors of consistent condom use among young psychoactive substance users in Kampala's informal settlements, Uganda

Introduction

The use of psychoactive substances increases the likelihood of unprotected sexual intercourse with individuals whose health status is not known, and consequently sexually transmitted infections, especially among young people. Despite this risk, there is limited evidence of the predictors of consistent condom use among young psychoactive substance users (YPSUs) in informal settings. This study examined the predictors of condom use among YPSUs in Kampala's informal settlements, Uganda.

Methods

A cross-sectional study was conducted among 768 YPSUs. Respondent-driven sampling was used to recruit respondents. A structured questionnaire was used to collect respondent data on condom use. Data were analysed using Stata version 15.0. Prevalence ratios (PR) were used to determine the predictors of consistent condom use.

Results

Out of the 744 YPSUs, only 37.4% of the respondents reported consistent condom use in the last 30 days. The prevalence of condom use was statistically lower among young people aged 20-24 years (35.4%) compared to those aged 18-19 years (43.7%), and among the married (17.3%) compared to respondents with a "single" marital status (43.0%). Being married (PR 0.42, 95% CI: 0.30-0.59), longer duration between meeting the most recent partner and having initial sexual contact with them (7 months to 1 year: PR 0.56, 95% CI: 0.36-0.88; more than a year: PR 0.36, 95% CI: 0.17-0.75) was negatively associated with consistent condom use. Spending less than 24 h between meeting the most recent partner and having initial sexual contact was positively associated with consistent condom use (PR 1.60, 95% CI: 1.24-2.08).

Conclusion

The prevalence of consistent condom use in the last 30 days among YPSUs was low. Marital status and the duration between meeting the most recent partner and initial sexual contact predicted consistent condom use. There is a need to intensify awareness on the importance of consistent condom use among young people.

A systematic review of substance use and substance use disorder research in Kenya

Objectives

The burden of substance use in Kenya is significant. The objective of this study was to systematically summarize existing literature on substance use in Kenya, identify research gaps, and provide directions for future research.

Methods

This systematic review was conducted in line with the PRISMA guidelines. We conducted a search of 5 bibliographic databases (PubMed, PsychINFO, Web of Science, Cumulative Index of Nursing and Allied Professionals (CINAHL) and Cochrane Library) from inception until 20 August 2020. In addition, we searched all the volumes of the official journal of the National Authority for the Campaign Against Alcohol & Drug Abuse (the African Journal of Alcohol and Drug Abuse). The results of eligible studies have been summarized descriptively and organized by three broad categories including: studies evaluating the epidemiology of substance use, studies evaluating interventions and programs, and qualitative studies exploring various themes on substance use other than interventions. The quality of the included studies was assessed with the Quality Assessment Tool for Studies with Diverse Designs.

Results

Of the 185 studies that were eligible for inclusion, 144 investigated the epidemiology of substance use, 23 qualitatively explored various substance use related themes, and 18 evaluated substance use interventions and programs. Key evidence gaps emerged. Few studies had explored the epidemiology of hallucinogen, prescription medication, ecstasy, injecting drug use, and emerging substance use. Vulnerable populations such as pregnant women, and persons with physical disability had been under-represented within the epidemiological and qualitative work. No intervention study had been conducted among children and adolescents. Most interventions had focused on alcohol to the exclusion of other prevalent substances such as tobacco and cannabis. Little had been done to evaluate digital and population-level interventions.

Conclusion

The results of this systematic review provide important directions for future substance use research in Kenya.

Multiple sexual partnerships and associated factors among young psychoactive-substance-users in informal settlements in Kampala, Uganda

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.

Multi-level experiences and determinants of alcohol misuse and illicit drug use among occupational groups at high-risk of HIV in sub-Saharan Africa: A thematic synthesis of qualitative findings

Occupational groups at high-risk of HIV in sub-Saharan Africa (SSA) may be at increased risk of substance use because of occupation-related factors. We synthesised qualitative data on determinants and context of alcohol misuse and illicit drug use in these groups. We systematically searched five databases for qualitative studies reporting on alcohol misuse or illicit drug use in fisherfolk, uniformed personnel, miners, truckers, motorcycle taxi riders, and sex workers in SSA. Qualitative data and interpretations were extracted and synthesised using a systematic iterative process to capture themes and overarching concepts. We searched for papers published prior to January 2018. We identified 5692 papers, and included 21 papers in our review, published from 1993 to 2017. Most studies were conducted among fisherfolk (n = 4) or sex workers (n = 12). Ten papers reported on alcohol use alone, three on illicit drug use alone and eight on both. Substance use was commonly examined in the context of work and risky behaviour, key drivers identified included transactional sex, availability of disposable income, poverty, gender inequalities and work/living environments. Substance use was linked to risky behaviour and reduced perceived susceptibility to HIV. Our review underscores the importance of multilevel, integrated HIV prevention and harm reduction interventions in these settings.
