a
Baseline moderate to vigorous-intensity physical activity (MVPA) was measured by an interviewer-administered questionnaire assessing the duration, frequency and intensity of 20 recreational activities over the prior 6 months.
b
p-values for a difference in means were generated using the t-test for two categories or ANOVA for multiple categories.
