Association Between Perceived Discrimination and Alcohol and Tobacco Consumption in ELSA-Brasil Cohort: Focusing on Gender Differences

Background: Discrimination is detrimental to physical and mental health, particularly insofar as health-risk behaviors are concerned. Particular attention has been paid to excess alcohol consumption and smoking in view of the ready availability of these substances in Western societies. Objectives: To determine whether an association exists between perceived discrimination and excess alcohol intake and smoking in women and men enrolled in the ELSA-Brasil cohort study. Methods: The sample included in the ELSA-Brasil cohort consisted of 15,105 civil servants. Data from waves 1 and 2 of the study were used. A multidimensional questionnaire was used to collect sociodemographic characteristics and evaluate perceived discrimination, alcohol consumption, and smoking. Results: An association was found between excess alcohol intake and perceived discrimination only in the men, with this association remaining significant in the youngest age group, in university-educated individuals, and in the group classified as middle-class. An association was found between smoking and lifetime perceived discrimination in women, particularly in those ≥60?years of age, brown-skinned women, those who had completed elementary school, and those classified as upper social class. This same association was found in the men, mainly those of 50–59?years of age, white-skinned males, those who had completed high school, those with a university education, and those classified as upper social class. Conclusions/Importance: Investing in public health policies aimed at combating the different forms of discrimination would appear essential. Not only does discrimination contribute to social injustice, but it also encourages health-risk behaviors such as excess alcohol intake and smoking.
