The purpose of this study was to investigate the analysis of gender and accelerometer-based physical activity on whole body insulin sensitivity in obese children. In a cross-sectional design, a total of 78 obese children (44 boys and 34 girls) in the fifth and sixth grade were voluntarily recruited from an elementary school located at the Gyeonggi-Do. Following an overnight fast, body fatness parameters such body mass index(BMI), percent body fat and waist circumference and resting blood pressures were measured with standardized protocols. Venous blood samples were collected for blood lipids and glucose and insulin. Fasting glucose (mM) and insulin (uIU/mL) were used to calculated homeostasis model assessment for insulin resistance (HOMA-IR). Daily physical activities were classified as low, moderate and vigorous intensity using a computer software provided by the company. Independent t-tests were used to test any significant differences in measured parameters between boys and girls. Further analyses were performed to assess any gender differences in the measured parameters within a subgroup who met a current recommendation (60 minutes or more per day) of moderate to vigorous physical activity for children. The total group analyses showed that (1) girls had significantly higher values in percent body fat (p=.003), total cholesterol (p=.012), triglycerides (p=.040), fasting glucose (p=.631) and insulin (p<.001) and HOMA-IR (p=.001) than boys and (2) boys had significantly higher values in accelerometer-based low (p=.009), moderate (p=.015) and vigorous (p=.005) physical activity than girls. Subgroup analyses showed that (1) group differences in total cholesterol (p=.034), triglycerides (p=.095), HDL-C (p=.031), fasting glucose (p=.527) and insulin (p=.002) and HOMA-IR (p=.005) were found between the boys and girls limited to children who did not met the daily recommendation for moderate to vigorous physical activity and (2) yet the gender differences in those parameters were not statistically significant between the boys and girls limited to children who met the daily recommendation for moderate to vigorous physical activity. In conclusion, the current findings of the study suggest that moderate to vigorous physical activity plays a critical role in determining gender differences in blood lipids and insulin resistance syndrome markers between obese boys and girls. Thus, promotion of moderate to vigorous physical activity should be a key component of lifestyle interventions against insulin resistance in obese children.
