Methods Using the method of stratified cluster random sampling, this study recruited 7 to 12 year-old primary students (n=4 294) in Guangzhou. The physical examination and questionnaire were used to collect the sedentary lifestyles after school and cardiometabolic risk factors, analyzing the impact of different aedentary behavoir time after school on cardiometabolic risk factors. Results The average sedentary time after school per day were 194.3 min (boys: 200.3 min; girls: 187.3 min). Inter-quartile ranges of sedentary time after school per day were ≤130.0, 131.0-180.0, 181.0-240.0, and ≥241.0 min/d. Controlling for confounding factors, the odd ratios (OR) of central obesity, overweight/obesity, high TC status, high TG status and high LDL-C status in the highest compared to the lowest quartile of sedentary time after school per day were 1.39 (95%CI:1.08-1.80), 1.44 (95%CI:1.16-1.80), 1.26(95%CI:1.05-1.51), 1.63(95%CI:1.34-1.98), 1.28(95%CI:1.06-1.55), respectively. Conclusions Sedentary lifestyles have a positive relationship with childhood central obesity, overweight/obesity and dyslipidemia in primary school children.
