A recent Japanese study indicated that more sedentary time and less physical activity (PA) can damage cardiometabolic health, leading to illnesses including metabolic syndrome (Mets).


"Reallocating 30 minutes of inactive time to light physical activity was substantially linked with decreased BMI, visceral fat, insulin resistance, triglyceride, and MetS levels, as well as improved muscle mass and HDL-C levels," the researchers wrote.


The cross-sectional study gathered information from 758 adults who were required to wear an accelerometer to track their sedentary and active activity. The average accelerometer wear duration found that sedentary activity accounted for 67.9% of the 15.6 hours per day. Meanwhile, 4.58 and 0.42 hours per day were spent in light and moderate-to-vigorous PA, respectively.


A substantial relationship between increased sedentary time and cardiometabolic risk variables was discovered using multiple linear regression analysis. Participants in the top quartiles of sedentary time, for example, had significantly increased visceral fat area, homeostasis model evaluation of insulin resistance, triglyceride levels, and low-density lipoprotein cholesterol (all with ptrend=0.001).


Those with the most sedentary time, on the other hand, had significantly decreased muscle mass and HDL-C (ptrend<0.001 for both).


MetS (odds ratio [OR], 2.52, 95 percent confidence interval [CI], 1.34–4.73; ptrend=0.004), as well as its components, abdominal obesity (OR, 2.79, 95 percent CI, 1.63–4.75; ptrend<0.001) and dyslipidemia (OR, 1.81, 95 percent CI, 1.08–3.04; ptrend=0.018), were also linked to excessive sedentary time.
