PUBLIC DRINKING VENUES AS RISK ENVIRONMENTS: COMMERCIAL SEX, ALCOHOL AND VIOLENCE IN A LARGE INFORMAL SETTLEMENT IN NAIROBI, KENYA

Spatial Analysis of the Alcohol, Intimate Partner Violence, and HIV Syndemic Among Women in South Africa

The co-occurrence of and synergistic interactions between substance abuse, violence, and HIV, known as the "SAVA syndemic," is thought to be a driver of women's elevated risk for HIV in sub-Saharan Africa. This study uses data from the 2016 South African Demographic and Health Survey (DHS) and the 2016 South African Census to examine geospatial associations between alcohol use, intimate partner violence (IPV), unprotected sex, and HIV status among a population-based sample of 8528 South African women (age 15-49). Results support the geographic clustering of alcohol use, unprotected sex, and IPV, but not HIV, and geospatial clustering of HIV alone. This study highlights the need for geographically-tailored interventions to address syndemics through integrated interventions, such as those simultaneously focused on alcohol, IPV, and sexual risk reduction, and points to the need for more targeted research to link these factors to HIV from a place-based risk perspective.

Harmful Alcohol Use and Associated Socio-Structural Factors among Female Sex Workers Initiating HIV Pre-Exposure Prophylaxis in Dar es Salaam, Tanzania

Harmful alcohol use is an important risk factor for premature mortality and morbidity and associated with increased HIV risk and lower uptake of and adherence to HIV interventions. This study aimed to assess the extent of harmful alcohol use and associated socio-structural vulnerability factors among female sex workers in Dar es Salaam, Tanzania, a key population in the HIV epidemic. Data from a study of female sex workers initiating pre-exposure prophylaxis (PrEP) recruited through respondent driven sampling were used. We assessed harmful alcohol use with the Alcohol Use Disorders Identification Test (AUDIT) defined as having an AUDIT score ≥ 16. Associations between harmful alcohol use and socio-structural factors were assessed using logistic regression with marginal standardization. Of the 470 women recruited, more than one third (37.3%) had a drinking pattern suggestive of harmful alcohol use. Such use was independently associated with sex work-related mobility (aPR: 1.36, 95% CI: 1.11-1.61), arrest/incarceration (aPR: 1.55, 95% CI: 1.27-1.84) and gender-based violence (aPR: 1.31, 95% CI: 1.06-1.56). The high prevalence of harmful alcohol use and the interconnectedness with socio-structural factors indicate a need for a holistic programmatic approach to health for female sex workers. Programming should not solely direct attention to individual behavior but also include strategies aiming to address socio-structural vulnerabilities.

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.

Evolution of Condom Use Among a 5-Year Cohort of Female Sex Workers in Zambia

Observing sexual behaviour change over time could help develop behavioural HIV prevention interventions for female sex workers in Zambia, where these interventions are lacking. We investigated the evolution of consistent condom use among female sex workers and their clients and steady partners. Participants were recruited into an HIV incidence cohort from 2012 to 2017. At each visit, women received HIV counselling and testing, screening for sexually transmitted infections (STIs) and free condoms. Our outcome was reported consistent (100%) condom use in the previous month with steady partners, repeat clients, and non-repeat clients. Consistent condom use at baseline was highest with non-repeat clients (36%) followed by repeat clients (27%) and steady partners (17%). Consistent condom use between baseline and Month 42 increased by 35% with steady partners, 39% with repeat clients and 41% with non-repeat clients. Access to condoms, HIV/STI counselling and testing promoted positive sexual behaviour change.

The built environment and perceived HIV risk among young women living in the peri-urban slum of Kibra, Nairobi, Kenya

This study reports on the lived experiences of young women living in a peri-urban slum in Kenya and its impact on perceived HIV risk and prevention needs. Guided by the theory of gender and power and postcolonial theory, 73 women 15-24 years of age participated in individual and focus group interviews. Results revealed that the built environment inside and outside the home such as inadequate physical space and lack of security impacted perceived HIV risk. To have meaningful and sustainable change, HIV prevention efforts must address social structures that impact daily lived experiences of young women.

Loss to follow-up among female sex workers in Zambia: findings from a five-year HIV-incidence cohort

HIV-incidence studies are used to identify at-risk populations for HIV-prevention trials and interventions, but loss to follow-up (LTFU) can bias results if participants who remain differ from those who drop out. We investigated the incidence of and factors associated with LTFU among Zambian female sex workers (FSWs) in an HIV-incidence cohort from 2012 to 2017. Enrolled participants returned at month one, month three and quarterly thereafter. FSWs were considered LTFU if they missed six consecutive months, or if their last visit was six months before the study end date. Of 420 FSWs, 139 (33%) were LTFU at a rate of 15.7 per 100 person years. In multivariable analysis, LTFU was greater for FSWs who never used alcohol, began sex work above the age of consent, and had a lower volume of new clients. Our study appeared to retain FSWs in most need of HIV-prevention services offered at follow-up.

Factors associated with alcohol use before sex among HIV-negative female sex workers in Zambia

Female sex workers (FSWs) are at high risk of HIV infection. Alcohol use prior to sex can compound this risk. We investigated the factors associated with having sex under the influence of alcohol among Zambian FSWs. Community health workers and peer FSWs recruited 331 HIV-negative FSWs in Lusaka and Ndola. In a cross-sectional survey, we asked FSWs how often they had sex under the influence of alcohol in the previous month and categorised responses as ‘always’ and ‘not always’. The adjusted odds ratios (AORs) of always having sex under the influence of alcohol were higher among FSWs who charged clients medium (AOR: 2.20, 95% confidence interval [CI]: 1.04–4.68) and low fees (AOR: 2.65, 95% CI: 1.26–5.60) for sex versus high fees; received 9–19 (AOR: 2.37, 95% CI: 1.15–4.91) and 20 or more clients per month (AOR: 3.06, 95% CI: 1.47–6.37) versus up to 8 clients per month; and never used condoms versus always used condoms with clients (AOR: 4.21, 95% CI: 1.53–11.55). FSWs who always used alcohol before sex appeared more likely to engage in riskier sex and charge clients lower fees. Interventions for financial empowerment and alcohol risk reduction should complement existing HIV prevention interventions for FSWs.

HIV/AIDS mortality attributable to alcohol use in South Africa: a comparative risk assessment by socioeconomic status

OBJECTIVES

To quantify HIV/AIDS mortality attributable to alcohol use in the adult general population of South Africa in 2012 by socioeconomic status (SES).

DESIGN

Comparative risk assessment based on secondary individual data, aggregate data and risk relations reported in the literature.

SETTING

South African adult general population.

PARTICIPANTS

For metrics of alcohol use by SES, sex and age: 27 070 adults that participated in a nationally representative survey in 2012. For HRs of dying from HIV/AIDS by SES: 87 029 adults that participated in a cohort study (years 2000 to 2014) based out of the Umkhanyakude district, KwaZulu-Natal.

MAIN OUTCOME MEASURES

Alcohol-attributable fractions for HIV/AIDS mortality by SES, age and sex were calculated based on the risk of engaging in condom-unprotected sex under the influence of alcohol and interactions between SES and alcohol use. Age-standardised HIV/AIDS mortality rates attributable to alcohol by SES and sex were estimated using alcohol-attributable fractions and SES-specific and sex-specific death counts. Rate ratios were calculated comparing age-standardised rates in low versus high SES by sex.

RESULTS

The age-standardised HIV/AIDS mortality rate attributable to alcohol was 31.0 (95% uncertainty interval (UI) 21.6 to 41.3) and 229.6 (95% UI 108.8 to 351.6) deaths per 100 000 adults for men of high and low SES, respectively. For women the respective rates were 10.8 (95% UI 5.5 to 16.1) and 75.5 (95% UI 31.2 to 144.9). The rate ratio was 7.4 (95% UI 3.4 to 13.2) for men and 7.0 (95% UI 2.8 to 18.2) for women. Sensitivity analyses corroborated marked differences in alcohol-attributable HIV/AIDS mortality, with rate ratios between 2.7 (95% UI 0.8 to 7.6; women) and 15.1 (95% UI 6.8 to 27.7; men).

CONCLUSIONS

The present study showed that alcohol use contributed considerably to the socioeconomic differences in HIV/AIDS mortality. Targeting HIV infection under the influence of alcohol is a promising strategy for interventions to reduce the HIV/AIDS burden and related socioeconomic differences in South Africa.
