This study examined physical activity in leisure time and at work as estimated by the Global Physical Activity Questionnaire (GPAQ) and the associations between both total and domain-specific physical activity with cardiovascular risk factors in a population-based Vietnamese sample. Participants (n = 1978) were 25- to 64-year-old adults selected by stratified multistage sampling. Leisure activity contributed to <5% of total moderate and vigorous activity and was not associated with cardiovascular risk factors. Total moderate and vigorous activity was associated with body composition (r = -0.16 to -0.22; P < .001), blood glucose (r = -0.07; P < .05), and total cholesterol (r = -0.17; P < .001) for men and with total cholesterol (r = -0.07; P < .05) for women after adjusting for age. Further adjustment for smoking and alcohol intake made negligible changes. These associations were largely driven by work activity, which accounted for 80% of total activity.
