The Brazilian Longitudinal Study of Adult Health (ELSA-Brasil): Factors Related to Smoking Cessation

Background Smoking cessation is not an easy accomplishment. However, the benefits are several for those who do it, such as cardiovascular risk reduction 1 year after quitting smoking. This study aimed to verify the factors related to smoking cessation in civil servants of The Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Methods This study had a longitudinal design using data from a prospective cohort of civil servants (ELSA-Brasil). Our variable of interest was smoking cessation. The relationship between socio-demographic characteristics, job stress, health-related variables, legislation, and smoking cessation was analyzed by Cox proportional hazard models. The analyses were stratified by gender. Second-hand smoke exposure, age, education, excessive alcohol consumption, common mental disorder, and smoking control law were the variables considered in the final model. Results Information of 2020 women and 2429 men was analyzed. Individuals without second-hand smoke exposure, with up to 49 years of age, with higher education, without excessive alcohol consumption, without common mental disorders, and who initiated smoking in 1989 or after the smoking control law had a higher risk of stopping smoking. The risks magnitudes were higher for women. Conclusions Our study reinforces the necessity of alcohol consumption regulation, the relevance of Public Health Policies, and the need for more smoking cessation measures focused on men, on people with mental disorders, alcoholism, and older adults. Also, our results did not show significant risks regarding the psychosocial working environment.
