PITANGA, Francisco José Gondim et al. Sociodemographic factors associated with different domains of physical activity in adults of black ethnicity. Rev. bras. epidemiol. [online]. 2012, vol.15, n.2, pp.363-375. ISSN 1415-790X. http://dx.doi.org/10.1590/S1415-790X2012000200014.
OBJECTIVE: To analyze the prevalence and sociodemographic factors associated with different domains of physical activity among adults of black ethnicity. METHODS: Cross-sectional study with a sample of 2,305 black individuals from 20-96 years of age, 902 (39.1%) of which men living in the city of Salvador, Bahia, Brazil. Sociodemographic variables analyzed were: gender, age, schooling, socioeconomic status (SES), marital status, racial discrimination at work/school (RDWE), in public (RDPUP) and private (RDPRP) places and perception of police (PPN) /violence in the neighborhood (PVN), as well as total physical activity (TPA) in its different domains: leisure time (LTPA), work (WPA), commuting (CPA) and household activity (HPA). Associations were analyzed using chi-square tests, chi-square trend and prevalence ratio (PR). We also used logistic regression analysis to estimate the odds ratio (OR) with a 95%confidence interval. RESULTS: The proportions of active individuals were 39.1% for TPA, 11.2% for LTPA, 9.6% for WPA, 23.7% for CPA and 33.7% for HPA. TPA was positively associated with higher schooling and inversely associated with male gender, age over 60 years and with no PPN. LTPA was positively associated with male gender, higher schooling and higher SES. WPA was inversely associated with age over 60 years and positively associated with male gender, higher schooling and no PPN. CPA was inversely associated with age over 60 years and positively associated with male gender. HPA was inversely associated with male gender, age over 60 years and no PPN and positively associated with higher schooling and SES. CONCLUSION: Socio-demographic factors, particularly gender, age and schooling were associated with different domains of physical activity among adults of black ethnicity.
