Results are expressed as mean±SEM for continuous variables and as OR and (95% CI) for categorical variables. Statistical analysis by analysis of variance for continuous variables and by logistic regression for categorical variables, adjusted for sex (male, female), age (continuous), BMI categories (normal, overweight, obese), smoking status (never, former, current), educational level (low, medium, high).
*N=76 as several variables were dropped due to collinearity.
BMI, body mass index; MVPA, moderate and vigorous physical activity; NC, not computable; PA, physical activity.
