Background.From a public health perspective, the study of socio-demographic factors related to physical activity is important in order to identify subgroups for intervention programs.Objective.This study aimed to identify the prevalence of, and the socio-demographic correlates related to, the achievement of recommended physical activity levels.Methods.Using data from the European Social Survey round 6, physical activity and socio-demographic characteristics were collected, in 2012, from 39,278 European adults (18,272 men, 21,006 women), aged 18–65 years, from 28 countries. The question of meeting physical activity guidelines was assessed using World Health Organization criteria.Results.A total of 64.50% (63.36% men, 66.49% women) attained physical activity recommended levels. The likelihood of attaining physical activity recommendations was higher in the 55–64 years age group (men: OR = 1.22,p< 0.05; women: OR = 1.66,p< 0.001), among those who had secondary education (men: OR = 1.28,p< 0.01; women: OR = 1.26,p< 0.05), among those who lived in rural areas (men: OR = 1.20,p< 0.001; women: OR = 1.10,p< 0.05), and among those who had three or more people living at home (men: OR = 1.40,p< 0.001; women: OR = 1.43,p< 0.001). On the other hand, attaining physical activity recommendations was negatively associated with being unemployed (men: OR = 0.70,p< 0.001; women: OR = 0.87,p< 0.05), being a student (OR = 0.56,p< 0.001; women: OR = 0.64,p< 0.01), being a retired person (men: OR = 0.86,p< 0.05) and with having a higher household income (OR = 0.80,p< 0.001; women: OR = 0.81,p< 0.01).Conclusions.This research helped clarify that, as the promotion of physical activity is critical to sustain health and prevent disease, socio-demographic factors are important to consider when planning the increase of physical activity.
