Alcohol use disorder and associated factors among individuals living with HIV in Hawassa City, Ethiopia: a facility based cross- sectional study
Substance Abuse Treatment, Prevention, and Policy volume 14, Article number: 22 (2019)
Individuals living with HIV/AIDS with co-occurring harmful alcohol use may require specialized intervention or even multi-disciplinary team follow-up and management. This study was aimed to assess alcohol use disorder and associated factors among people living with HIV/AIDS in Hawassa city, Ethiopia, 2019.
A facility based cross-sectional study was conducted among 195 people living with HIV/AIDS who had follow-up visit at Hawassa University Comprehensive Specialized hospital. A systematic sampling technique was used to recruit the study participants. Alcohol used disorders identification test (AUDIT) was used to measure alcohol consumption, drinking behaviors, and alcohol-related problems. The binary logistic regression model was used to see the association between alcohol use disorder (AUD) and the independent variables. The strength of association was measured by odds ratios with 95% confidence intervals. Statistical significance declared at P < 0.05.
The mean age of the study participants was 29.88 (±SD = 10.89) years. The magnitude of alcohol use disorder among people living with HIV/AIDS was 31.8%. Being male [AOR = 2.43, (95% CI: 1.76, 5.76)], having poor social support [AOR = 1.34, (95% CI: 1.12, 6.73)], being medication non-adherent [AOR = 1.78, (95% CI: 1.33, 6.79)], current khat chewing [AOR = 1.67, (95% CI: 1.16, 5.45)] and current cigarette smoking [AOR = 3.76, (95% CI: 2.16, 7.54)] had statistically significant association with alcohol use disorder.
In the current study, magnitude of alcohol use disorder among people living with HIV was high and, calls for integrating services provided to HIV patients in HIV care and treatment clinic which enhances timely detection and management of AUD cases. This also alerts the stakeholders in HIV prevention and control programs to invest a greater efforts to retain patients in addiction treatment and rehabilitation centers. Lastly, appropriate screening and health education on consequences of alcohol use disorder is warranted.
Alcohol use disorder increases hospitalization and have negative effects on the life expectancy of patients infected with the human immunodeficiency virus (HIV) . Alcohol can aggravate immunosuppression, impair cognitive function, often have detectable viral levels, and alcohol consumption may reduce patient adherence to ART, which can lead to treatment failure and leads to drug resistance to antiretroviral [2,3,4,5]. Moreover, hazardous alcohol use increases sexual risk behaviors for unprotected sex practice that leads to disseminating drug exposed virus to the public [2,3,4,5,6].
Alcohol misuse is among in the group of problem in low-income countries including Ethiopia . A study conducted on drug and alcohol abuse in Ethiopia revealed that the prevalence of hazardous alcohol use and alcohol dependence was 3 and 1.5% in general population respectively . Different studies showed that higher prevalence of AUD among HIV patients; 32% in Ethiopia , 38.4% in four African country , 42% in Nepal , 39.4% in Nigeria  and 74.3% in New York, USA .
The most significant cause of ART interruption especially among men is harmful or hazardous alcohol use [5, 6]. The effectiveness of antiretroviral medication is highly dependent on patient adherence to highly active antiretroviral therapy (HAART) to significantly decrease HIV-related morbidity and mortality [3,4,5]. Being male sex, severe or moderate anxiety, being a college student, HIV related stigma and illicit drug use including tobacco are highly associated with alcohol use, and illicit drug use and CD4 count greater than or equal to 500 cells/microliter are highly associated with hazardous drug use [9,10,11,12,13].
Health care providers are more often missing alcohol use problems in patients with less severe HIV infection and those without evidence of chronic diseases including liver disease . Using specific instruments for assessing alcohol consumption enables the identification of less evident cases of alcohol abuse in HIV screening [14,15,16,17,18,19]. Patients with HIV/AIDS with hazardous or harmful alcohol use may require specialized intervention or even multi-disciplinary team follow-up and management [14,15,16,17,18,19,20,21,22]. This alerts the stakeholders in HIV prevention and control programs to invest greater efforts to retain patients in addiction treatment and rehabilitation centers [20, 21].
Early detection of alcohol use disorder in HIV infected patients may strengthen the effectiveness of the medication which is significant for poor therapeutic adherence [20,21,22]. There is limited data concerning alcohol use disorder in HIV infected patients in Ethiopia for tailored prevention, diagnosis and treatment care in local context. Therefore, this cross-sectional study was aimed to assess the magnitude of alcohol use disorder and associated factors among patients with HIV/AIDS in Ethiopia.
Study design and setting
A facility based cross-sectional study was carried out to assess the epidemiology of alcohol use disorder and associated factors among patients living with HIV at Hawassa University Comprehensive Specialized Hospital, Hawassa, Ethiopia. This hospital is the only comprehensive specialized hospital found in Hawassa city, Ethiopia, which is situated 273 km from Addis Ababa, Ethiopia. It delivers both outpatient and inpatient services for more than 18 million population with more than 400 beds. In average, the hospital provides services for people living with HIV/AIDS at the ART clinic for more than 50 patients/day.
Sample size determination and sampling procedure
Single population proportion formula was used to get the required sample size using prevalence of AUD among HIV patients in Ethiopia, 14.2% , with a 95% confidence interval and 5% of margin error. We used systematic sampling techniques to recruit the study participants through three intervals (K = 3). The first study participant among the 1st three participants selected through the lottery method. Among individuals who had a follow up visit at ART clinic, a total of 195 individuals with HIV who were with age of ≥18 years were selected for the study. Two study participants excluded from the study due to their hearing problems and critical stage of their illness.
Data collection instruments and procedures
Four trained psychiatry nurses who had taken three days training on data collection had collected the data through an interviewer-administered questionnaire. Alcohol used disorders identification test (AUDIT) was used to measure alcohol consumption, drinking behaviors, and alcohol-related problems. It is a 10-items screening tool which was developed by WHO to identify alcohol use disorders for the last 12 months. The score of > eight or more in AUDIT was considered as alcohol use disorder. The scale has been validated in different ethnic groups and across genders with the sensitivity of 94.1% and specificity of 91.7%, is well-suited for use in primary care settings . It was translated into Amharic which was the main languages spoken in the study area and back-translated to English by English language experts. It was tested in our pretest and highly reliable in our study (Cronbach’s alpha =0.94). Perceived HIV stigma scale was used to assess self-felt stigma by HIV patients. It is a Likert type of scale with four possible answers (strongly disagree = 1, disagree = 2, agree =3 and strongly agree = 4) to questions or statements on their opinions and feeling concerning how persons behave towards due to their HIV illness [25, 26]. ART medication adherence was looked at using the Morisky Medication Adherence Scale which is validated for the measure of medication non-adherence in a variety of patient populations and with over 110 versions and over 80 translations . The Oslo 3-items social support scale was used to estimate the level of social support of the study participant’s percept. It is a scale with the sum score ranging from 3 to 14, 3–8 is” poor support”, 9–11 is” moderate support” and 12–14 is” strong support”. In this study, we consider good social support when the sum score is ≥9. It has been used in many population-based studies in Ethiopia . Perceived HIV stigma, Morisky Medication Adherence Scale and Oslo social support scale were also highly reliable in this study with Cronbach’s alpha of 0.88, 0.92 and 0.94 respectively.
Data processing and analyses
The checked and coded data was entered into Epi-Info version 7.0. Then transported to SPSS version 22 to analyze the data. Descriptive (frequency) statistics was done to get the distribution of socio-demographic, clinical and environmental factors and, a prevalence of AUD. The binary logistic regression model was used to see the association between AUD and the independent variables. Variables with a P-value of 0.20 and other variables of interest were entered into the multivariable logistic regression analysis. The strength of association was measured by odds ratios with 95% confidence intervals. Statistical significance was declared at P < 0.05.
Socio-demographic characteristics of the study participants
A total of 195 individuals with HIV enrolled in the study with response rate of 98.9%. The mean age of the study participants was 29.88 (±SD = 10.89) years. Most of the study participants were in the age group of 35–44 years (40%), married (55.4) and living with their family (74.4%) (Table 1).
Clinical and psychosocial characteristics of the study participants
Among the respondents, 45.1 were with the illness duration of 5–10 years, 55% had good social support and 24.6% had TB/HIV coinfections (Table 2). Among the study participants who were classified as alcohol use disorder, 16.4% initiated drinking alcohol due to easily availability of alcohol, 13.8 and 11.8% started drinking alcohol due to peer pressure and lack of social support respectively (Table 3). Among those with AUD, 48.3% were preferred factory bottled beer, 35.4% were preferred locally brewed beer (‘tella’ and teji) and 19.4% were preferred arake.
Prevalence of alcohol use disorder and associated factors
The prevalence alcohol use disorder among people living with HIV using AUDIT with cut-off point ≥8 was 31.8%. Finding from binary logistic regression analysis revealed that being male, having poor social support, current khat chewing, current cigarette smoking and poor medication adherence were statistically significant association with alcohol use disorder (Table 4).
In this study, the prevalence of alcohol use disorder among individuals with HIV was 31.8% (CI: 25.1–33.4). The prevalence of this study was in-line with the other studies in Ethiopia which was 32.6% , 30.7% in Togo , 25.7% in Nepal , 28.6% in Brazil  and 27% in USA . On the other hand, the prevalence of AUD is lower than the studies in China which is 42.8%  and higher than the studies from Ethiopia which is 14.2%  and 14 in Nigeria . The difference in prevalence of alcohol use disorder could be due to the variation in the study setting, data collection instrument and the cutoff point of the instrument which was used to assess alcohol use disorder and the sample size in the study. In addition, the disparities in the magnitude might be due to variations in the underlying social, cultural and economic status among the study countries.
Males were 2.43 times more likely to have AUD when compared to females. This is in agreement with studies [9, 10, 23, 32]. Mostly, heavy drinking occurs among men when contrast to women and also biological differences among male and female could contribute to this difference .
AUD was more commonly seen among those individuals with poor social support. This is in-agreement to the other studies [9,10,11]. This could be due to the fact that getting minimal social support from their neighbors or any person might cause dissatisfaction in their life. As a result, they might use alcohol to get rid of their stress and dissatisfaction.
Poor medication adherence had a significant association with alcohol use disorder. Individuals with HIV who had poor medication adherence were 1.78 times more likely to have alcohol use disorder. None of the studies proved the relationship between alcohol and medication adherence. Alcohol intoxicated individuals might forget to take the medications due to their memory impairments as result of deficiency in vitamin B1 (Thiamine) due to alcohol drinking . On the other hand, they might use alcohol as a coping strategy for their psycho-social stressors associated with illness.
Chewing khat and smoking cigarette had a statistically significant association with AUD. This is in line with other studies in Ethiopia [9, 23] and four African countries , USA  and China  respectively. This might be due to the fact that these substances are commonly interrelated with each other . In addition to this, alcohol and cigarette (nicotine) could potentiate their rewarding effects and, cigarette smoking by itself bring down the intoxication and sedative effects of alcohol through stimulation .
In the current study, magnitude of alcohol use disorder among people living with HIV was high and calls for integrating services provided in HIV care and treatment clinic which enhances timely detection and management of AUD cases. Being male, having poor social support, current khat chewing, current cigarette smoking and poor medication adherence were statistically significant association with alcohol use disorder. This also alerts the stakeholders in HIV prevention and control programs to invest a greater efforts to retain patients in addiction treatment and rehabilitation centers. Lastly, appropriate screening and health education on consequences of alcohol use disorder is warranted.
Limitation of the study
The study used standardized data collection instruments. However, some instruments are not validated to Ethiopian culture. This might over or under estimate the prevalence of AUD in this study. Because it was cross-sectional study design, it did not allow establishing a temporal relationship between AUD and other significantly associated factors.
