Abstract
By the middle of the last century, changes in the Brazilian economy and society triggered a rapid demographic transition characterized by an increased number of older adults in the population. Thus, Brazil has witnessed population aging, which was accompanied by an increased incidence of non-communicable chronic diseases. Some risk factors for the development of the chronic non-communicable diseases have been well established, such as overweight, tobacco and alcohol consumption, inadequate nutrition, and physical inactivity. Additionally, sedentary behavior has been related to significant deleterious effects on health, such as diabetes mellitus type 2, obesity and mortality. The objective of this study was to investigate the association between sitting time and diabetes mellitus in older adults. A cross-sectional study was conducted in 24 municipalities in the Regional Health Superintendence of Uberaba, MG. Selected subjects answered a structured questionnaire and underwent anthropometric assessment. A total of 3,265 elderly subjects, with a median time spent sitting of 240.00 (P25th=137.14 and P75th=330.00) minutes/day and a 20.0% prevalence of diabetes mellitus were detected. Adjusted logistic regression analysis showed that a sitting time of more than 330.00 minutes/day was positively associated with diabetes mellitus (OR=1.351, 95%CI: 1.057-1.729). It was concluded that older adults who daily sit for long periods of time have higher chances of having diabetes compared to those who sit for less time.
