Abstract P278: Prevalence, Patterns and Correlates of Physical Activity Among the Adult Population of Four Cities in the Southern Cone of Latin America: Results from the CESCAS I study
Introduction: In the Southern Cone of Latin America physical inactivity has become the fifth most important determinant of death. There is no published data describing and comparing physical activity (PA) patterns among different cities in this region.
METHODS: CESCAS I is an observational, prospective cohort study entailing a probabilistic sample of 7524 representing the general adult population in four middle-size cities of the Southern Cone of Latin America. PA was assessed through the transcultural adapted questionnaire from the International Physical Activity Questionnaire long form. The indicator of PA intensity was expressed continuously, in metabolic equivalent task (MET) per minutes per week. We expressed the total PA score per week as “Total MET-minutes/week” constituted by the sum of Walking, Moderate and Vigorous MET minutes/week scores. Insufficient PA was defined as < Total 600 MET-minutes/week. Analyses were based on weighted data taking into account individual probabilities of inclusion and calibrated on national census data. Multiple linear regressions were conducted as secondary analyses to model for the predictors of low PA. RESULTS: Thirty-five percent of the population is insufficiently active, showing the highest prevalences in Temuco (42.0%), women (41.3%), and “retired or unemployed” status (44.4%). Considering the overall population, women spend one third of energy compared to men (median 989 vs. 2763 MET-minutes/week respectively) mainly because only 12.9% of women performed vigorous activities compared to 39.9% in men. Among those subjects who reported performing vigorous activities, the energy expended by women was much lower than that expended by men (median 2384 vs. 5567 MET-minutes/week, respectively). When the overall population by domain was analyzed, the highest energy expenditure was seen in occupational at the expense of the manual labor category (2856 and 4588 MET-minutes/week for women and men respectively). Analyzing those who reported expending some energy in occupational, we found that men expended more than double the energy compared to women at the expense of vigorous activities (7055 vs. 2803 MET-minutes/week, respectively). In the multivariable analysis insufficient PA was strongly related with the categories retired or unemployed (OR 2.22; 1.87- 2.64), office or clerical work (OR 1.96; 1.60- 2.40), being women (OR 1.56; 1.36- 1.78), obesity (OR 1.47; 1.24- 1.74) and college or university education (OR 1.29; 1.07- 1.56).
CONCLUSIONS: At least one third of the population did not reach the recommended PA levels necessary for promoting health and preventing diseases. Intervention strategies to promote leisure-time physical activity should be considered a health priority, especially in women.
