Relationship between Sitting Time and Insulin Resistance in 6931 U.S. Adults: The Mediating Role of Abdominal Adiposity

Table 3

Effect modification showing differences in mean L-HOMA-IR across the sitting time categories within individual waist circumference tertiles ().

Waist circumference category	Sitting time category
	Lowest tertile only ()						0.7	0.5022
Middle tertile only ()				0.2	0.8502
Highest tertile only ()				0.2	0.2144

L-HOMA-IR: natural log of HOMA-IR (homeostatic model assessment for insulin resistance); SE: standard error of the mean. None of the means on the same row were statistically different from each other. The means were adjusted for differences in the covariates: age, sex, race, year of assessment, BMI, physical activity, cigarette smoking, and waist circumference. Group frequencies are weighted values due to the person-level weighted adjustments used by NHANES.
