Physical activity levels and weight control status by body mass index, among adults – National Health and Nutrition Examination Survey 1999–2004

Abstract

Abstract Background Adequate levels of physical activity can assist with weight control efforts, however, only a modest number of national studies have examined the physical activity patterns by weight control status. This article aims to describe patterns of physical activity among men and women who reported engaging in weight control practices. Methods Data from the National Health and Nutrition Examination Survey (1999–2004) were used. The sample included 14,388 adults (aged ≥ 18 years), with measured weights and heights from which body mass index (BMI) (weight/height2; kg/m2) was calculated. Analyses were performed to describe the prevalence of engaging in levels of physical activity ( Results The prevalence of low levels of physical activity ( Conclusion Despite people's intentions to lose or maintain their weight, the majority of adults do not engage even in the minimum recommended level of physical activity. However, the prevalence of engaging in high levels of physical activity (150–420 minutes/week) was highest among those trying to lose or maintain weight than were with those not trying to lose/maintain weight. Regardless of weight control status, all adults should be encouraged to engage in regular physical activity.
