Objective. Determine the relationship between the prevalence of current tobacco use and smoker income levels in Latin America and the Caribbean (LAC). Methods. A systematic search was conducted in MEDLINE, EMBASE, CENTRAL, SOCINDEX, and LILACS databases. Studies from LAC published from January 1989 to December 2015 were included and analyzed by subgroups disaggregated by decade of data, country, bias risk, sex, and age group. Results. Of 1,254 studies evaluated by full text, 29 articles were included, of which 25 were chosen for meta-analysis. All included studies were cross-sectional or surveillance, and were primarily from Brazil and Mexico. Low income was associated with a higher prevalence of active tobacco use (odds ratio [OR] 1.62; 95% confidence interval [95% CI] 1.34–1.96 than high income (reference). A dose-response effect trend was observed: middle income (OR 1.23; 95% CI 1.00-1.52) and low income (OR 1.64; 95% CI 1.17-2.30). This association was greater in men (OR 2.22; 95% CI 1.77- 2.78) than in women (OR 1.6; 95% CI 1.11-2.47). Conclusions. An inverse relationship was observed between income and tobacco use prevalence. Further efforts are required to determine this relationship in special populations, such as adolescents and pregnant women. This research may be useful to policymakers by improving tobacco control strategies and characterizing public health equity issues.
