Sedentary Behavior and Cardiometabolic Risk Factors in Middle-aged Adults Living in A Brazilian Eastern Amazon City: A Cross Sectional Study

This study investigated the association of self-reported daily time in sedentary behavior with cardiometabolic risk factors in middle-aged adults living in a Brazilian eastern Amazon city. Middle-aged public civil servant living in Palma’s city participated in this cross-sectional study. Daily sedentary behavior and physical activity were measured, and anthropometric parameters and blood biochemical biomarkers were obtained. The results showed that total daily time in sedentary behavior measured using International Physical Activity Questionnaire associated positively with waist to height ratio [β = 0.008 (95% CI = 0.001; 0.016), p = 0.023] and body adiposity index [β = 0.570 (95% CI = 0.110; 1.020), p = 0.016]; and the time spent in passive transport measured using Longitudinal Aging Study Amsterdam - Sedentary Behavior Questionnaire was positively associated with neck [β = 4.420 (95% CI = 1.360; 7.480), p = 0.005) and waist circumference [β = 7.990 (95% CI = 3.490; 12.500), p = 0.005], waist to hip ratio [β = 0.060 (95% CI = 0.030; 0.100), p = 0.001), conicity index [0.050 (95% CI = 0.010; 0.080), p = 0.002], and the concentrations of triglycerides [β =38.500 (95% CI = 6.640; 70.390), p = 0.019] and insulin [β = 2.490 (95% CI = 1.030; 3.950), p = 0.001]. In conclusion, self-reported sedentary behavior is associated with anthropometric and biochemical risk factors for cardiometabolic diseases in the studied individuals.
