The Association of Daily Physical Activity Behaviors with Visceral Fat.

The association between health benefits and physical activity has received increasing attention among researchers working on the prevention of noncommunicable disease. However, the number of studies on the association between daytime activities and visceral fat is limited. In this study, we evaluated how daily physical activity behaviors impact the visceral adipose tissue (VAT) and body mass index (BMI). A total of 3543 participants (1240 men, 2303 women) were included in this cross-sectional study. The duration of daily physical activities (sedentary time, standing time, and walking time) was classified into the six categories. Multiple regression analysis was carried out to compare continuous variables. VAT and BMI were used as dependent variables, and the daily physical activities were used as independent variables. All results were expressed after adjusting for confounders, including sex, age, Brinkman index, daily alcohol consumption, sleeping time, and medication for hypertension, dyslipidemia, and diabetes. The multiple regression analysis showed that sedentary time was significantly associated with VAT (beta = 1.145, p value = 0.002), whereas standing time was negatively associated with VAT (beta = -0.763, p value = 0.043). Walking time was negatively and robustly associated with all depending variables as follows: BMI (beta = -0.172, p value = 0.001) and VAT (beta = -2.023, p value <0.001). This study showed that a daily behavior time affects the accumulation of VAT and BMI. A shift from sedentary time to standing or walking time might be a key population approach to prevent cardiometabolic diseases.
