Background:

We assessed the prevalence of reported alcohol use and its association with multimorbidity among adults aged 40 years and above in a rural, transitioning South African setting. Findings could potentially inform alcohol interventions integration in the prevention and treatment of chronic conditions.

Methods:

: We analysed data from the first wave of The Health and Ageing in Africa–a longitudinal Study in an INDEPTH community (HAALSI) nested within the Agincourt Health and Demographic Surveillance Systems (HDSS), conducted between November 2014 and November 2015 (n= 5059). We computed descriptive statistics and performed univariate analysis to determine factors independently associated with multimorbidity. Age, Body Mass Index, education, sex, and household wealth status and variables with a p-value< 0.20 in univariate analysis were included in multivariable Modified Poisson regression models. Any factors with a p-value of< 0.05 in the final models were considered statistically significant.

Results:

: The first wave of HAALSI was completed by 5059 participants aged 40 years and above and included 2714 (53.6%) females. The prevalence of reported ever alcohol use was 44.6%(n= 2253) and of these 51.9%(n= 1171) reported alcohol use in the last 30 days. The prevalence of multimorbidity that includes HIV was 59.6%(3014/5059) and for multimorbidity without HIV 52.5%(2657/5059). Alcohol use was associated with multimorbidity that includes HIV among all participants (RR: 1.05, 95% CI: 1.02-1.08), and separately for males (RR: 1.05, 95% CI: 1.00-1.10) and females (RR: 1.06, 95% CI: 1.02-1.11).
