Gender and psychosocial factors associated with healthy lifestyle in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) cohort: a cross-sectional study

Abstract

ObjectivesIt has been estimated that over 50% of the premature deaths occurring in Western countries can be attributed to causes rooted in lifestyle. In turn, leading a healthy lifestyle has also been associated with a wide range of psychosocial factors. Today, it is known that these differ among men and women. The present article aimed to identify, from a gender-based perspective, the psychosocial factors associated with healthy lifestyles in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) cohort, the largest study concerning adult health conducted in Latin America to date.DesignThis cross-sectional study was conducted using ELSA-Brasil baseline data, collected between 2008 and 2010.SettingSix Brazilian public higher education and research institutions.ParticipantsThe ELSA-Brasil cohort consists of approximately 15 000 employees (8218 women and 6887 men), both currently working and retired.Main outcome measuresThe lifestyle indicator was constructed by summing the scores attributed to four different behaviours.ResultsThe women of the ELSA-Brasil cohort have healthier lifestyles than men. In women, strong associations were found between a healthy lifestyle and age 60 years or older, Asian race and university level of education or higher. In men, being 60 years or older, of Asian or Caucasian race, having a high-school equivalent level of education or higher, being retired, having a housekeeper, having a good or very good self-perception of health and being satisfied with body image were the psychosocial factors associated with leading a healthy lifestyle.ConclusionsThe factors that influenced healthy lifestyles were found to differ among men and women, a fact that must be addressed when developing programmes designed to promote health.
