-This study aimed to estimate the prevalence of overweight and investigate its association with sociodemographic factors, physical activity level, hypercholesterolemia, and diabetes in civil servants of a university in the state of Paraná, Brazil. The research was conducted with 339 civil servants aged above 18 years. Overweight was analyzed by self-reported body mass index. Physical activity level was evaluated using a questionnaire. Sociodemographic data (sex, age, economic status, educational level, marital status, and working hours) and information on the chronic diseases of interest (hypercholesterolemia and diabetes) were obtained from self-report. The association between overweight and the other variables was investigated using binary logistic regression. The prevalence of overweight was 50.6%. The groups most susceptible to overweight were: male civil servants (OR: 2.04; CI: 1.30-3.22), those less than 12 years of education (OR: 2.46; IC: 1.43-4.23), who were insufficiently active (OR: 1.64; CI: 1.03-2.60), and those with hypercholesterolemia (OR: 2.28; CI: 1.32-3.96). This study concluded that more than a half of the sample was overweight and that this condition was associated with male sex, educational level below 12 years, insufficient physical activity, and hypercholesterolemia.
