Abstract:

Introduction: Regular physical activity is a cornerstone of diabetes therapy. However, it is known that in western societies, levels of physical activity (LPA) of the population are far below the desirable and physical inactivity is an important risk factor.Objectives: To evaluate the LPA and sedentary lifestyle of diabetic patients consulted in a Primary Healthcare Unit (PHU) in Portugal. To identify its association withage, gender, A1c hemoglobin (HbA1c) and body mass index (BMI). Methods: A cross-sectional study was conducted. A random sample of 400 was selected from the PHU list of diabetic patients (n = 1103). They were invited to answer the International Physical Activity Questionnaire, and data regarding age, gender, BMI, HbA1c was collected. Descriptive and inferential statistical analysis was performed using SPSSv20.0. Results: We obtained 128 valid questionnaires, mostly from men with an average age of 61 years. Regarding BMI: 11% had values <25kg/m2 and 50% ≥30kg/m2. HbA1c was ≤6,5% in 48% and>8% in 14%of the cases. Regarding physical activity, 31% reported low levels, 23% moderate and 46% high. While for structured exercise, only 46% spent>150 minutes weekly. Sixty-three percent reported to spend over 1000 minutes seated every week. A statistically significant correlation between sitting time and BMI was detected. Discussion: We identified low LPA and marked sedentary habits in the studied population, as well as a significant relation between physical inactivity and BMI was found. Conclusions: Family physicians should continue to encourage patients to engage in regular and structured physical activity, and to reduce inactivity periods.
