Odds ratios and 95% confidence intervals for leisure time sedentary behavior (LTSB) and usual occupational/domestic activity (UODA) and metabolic syndrome, stratified by meeting or not meeting physical activity recommendations (>150 min/week of moderate-to-vigorous physical activity) for men (A) and women (B) from the National Health and Nutrition Examination Survey 2003–2004 and 2005–2006. Referent was ≤2 hours/day versus ≥3 hours/day for LTSB, and referent was stand, walk, carry loads versus sitting for usual occupational/domestic activity categories. Covariates included: age, smoking (current vs. never and past vs. never), education (<high school degree vs. >high school degree and high school or General Educational Development [GED] vs. >high school degree), ethnicity (African American vs. European American, Mexican American, other vs. European American), and percent of fat in diet.
