Objectives-To describe the physical activity patterns across levels of obesity among US adults.Methods-The frequency, intensity and duration of physical activities were compared across obesity status in 7695 adults from NHANES, 1999-2006.Results-Significantly more normal weight adults engaged in moderate and vigorous intensity activities and for a longer duration than their overweight or obese counterparts. Lower intensity, longer duration walking contributed to nearly half of all moderate activity among obese subjects.Conclusions-Significant differences exist in intensity, frequency and duration of physical activity by weight status. This information suggests a targeted approach to current physical activity interventions be explored.
Our data demonstrate that young mice develop similar phenotypic, metabolic, and behavioral profiles when fed SD vs. LFD. The two diets may thus be equally appropriate as controls for an HFD, although some studies may want to consider differences in effects on cholesterol levels.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
