Simultaneidade de fatores de risco comportamentais à saúde em estudantes de uma universidade pública do sul do Brasil

Abstract

This study is part of the 2017/2018 Research Consortium of the Postgraduate Program in Epidemiology of the Federal University of Pelotas (UFPel). A cross-sectional, census-type study was carried out between November 2017 and july 2018 with freshmen from UFPel (n=1.716). In order to verify the clustering of risk factors, information on four outcomes was collected: physical inactivity, sedentary behavior, inadequate sleep time and smoking. Those who reported less than 150 minutes of physical activity per week were considered inactive, and those who reported spending at least five hours a day in front of an electronic screen were considered sedentary. Students who sleep less than seven hours a day were considered with inadequate sleep time, and smokers those that smoke at least one cigarette a day in the last month. To verify the clustering of risk factors, a cluster approach was used, which consists of the ratio between observed and expected values for each possible combination. It was considered cluster when the observed / expected ratio was greater than 1 and the 95% confidence interval did not comprise the unit. Only two clusters were identified in the general sample: inadequate sleep time only (O/E = 1.15; IC 95% 1.04; 1.27) and physical inactivity + sedentary behavior (O/E = 1.24; IC 95% 1.09; 1.41). More than 80% of college students presented at least one risk factor, with inadequate sleep time being the most prevalent (45.2%). The results suggest a homogeneity regarding the occurrence of simultaneity in risk factors. High prevalence was observed and these should not be neglected, since undergrad students are exposed to several risk factors whose may have synergistic effects.
