Implication

Systematic review reveals a nearly threefold increase in active tuberculosis risk among heavy drinkers, highlighting biological and social vulnerabilities linked to alcohol use.

Key Points

To systematically assess the relationship between alcohol consumption and the risk of active tuberculosis while evaluating the influence of confounding social and clinical factors.
Conducted a systematic literature review identifying 3 cohort and 18 case-control studies.
Categorized studies based on exposure thresholds (such as ≥40 g alcohol/day or clinical alcohol use disorder), tuberculosis outcome definitions, and controlled confounders.
Estimated pooled effect sizes across study subgroups and evaluated heterogeneity and publication bias.
The pooled relative risk for active tuberculosis across studies using a cut-off of ≥40 g alcohol per day or clinical diagnosis of alcohol use disorder was 3.50 (95% CI: 2.01–5.93).
After excluding small studies to account for suspected publication bias, the pooled relative risk remained elevated at 2.94 (95% CI: 1.89–4.59).
Subgroup analyses stratifying studies by sets of controlled confounders did not alter the risk estimates significantly or explain the significant heterogeneity observed across studies.
