Objetivo. Determinar la relación entre la prevalencia de consumo actual de tabaco y los
niveles de ingresos monetarios de fumadores en América Latina y el Caribe (ALC).
Métodos. Se realizó una búsqueda sistemática en bases de datos incluyendo MEDLINE,
EMBASE, CENTRAL, SOCINDEX y LILACS. Se incluyeron estudios de ALC publicados
desde enero 1989 hasta diciembre de 2015. Se realizaron análisis de subgrupos planeados por
década calendario de los datos, país, riesgo de sesgo, sexo y grupos de edad.
Resultados. De un total de 1 254 estudios evaluados por texto completo se incluyeron
29 artículos, de los cuales 25 fueron incorporados en metaanálisis. Todos los estudios
incluidos fueron de corte transversal o de vigilancia, la mayoría provenientes de Brasil y
de México.
Un bajo nivel de ingresos se asoció con una mayor prevalencia de tabaquismo activo (odds
ratio [OR] 1,62; intervalo de confianza de 95% [IC95%] 1,34–1,96) con respecto al nivel alto
(referencia). Se observó una tendencia de efecto dosis-respuesta: nivel medio de ingresos (OR
1,23; IC95% 1,00-1,52) y nivel bajo de ingresos (OR 1,64; IC95% 1,17-2,30). Esta asociación
fue mayor en hombres (OR 2,22; IC95% 1,77-2,78) que en mujeres (OR 1,6; IC95%
1,11-2,47).
Conclusiones. Se observó una relación inversa entre el nivel de ingresos y la prevalencia de
consumo de tabaco. Se requieren mayores esfuerzos para determinar esta relación en poblaciones
especiales como adolescentes o embarazadas. Esta investigación puede ser útil para los
decisores políticos al mejorar las estrategias de control del tabaco y para caracterizar cuestiones
de equidad en la salud pública. Objective. Determine the relationship between tobacco-use prevalence and smoker
income level in Latin America and the Caribbean (LAC).
Methods. A systematic search was carried out in MEDLINE, EMBASE, CENTRAL,
SOCINDEX, and LILACS databases. Studies from LAC published from January 1989
to December 2015 were included and were 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,
primarily from Brazil and Mexico.
Low income was associated with higher prevalence of active smoking (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 can be useful for
policymakers by improving tobacco control strategies and for characterizing public
health equity issues.
