Note: Boldface indicates significance. Obesity was classified from recalled weight at age 25 years (from Phase-1 questionnaire), and BMI at Phases 1 and 3. Coefficients are sitting time (hours/week). Model A is adjusted for age and gender only. Model B is additionally adjusted for employment grade, smoking status, weekly alcohol intake, self-rated health, physical functioning, daily walking time, and time spent in moderate- to vigorous-intensity physical activity.
