Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

The present study examined objectively measured physical activity in Malaysian children and compared the differences in physical levels between obese and healthy weight children. Eighty-six obese children were matched for age and sex with 86 healthy weight children with median age 9.5 years. Habitual physical activity and sedentary behaviour were measured over 5 days using Actigraph accelerometers. Time spent sedentary was significantly higher in the obese group (90% vs. 86% of daytime; p = 0.001). Moderate-to-vigorous-intensity physical activity was significantly higher in the healthy weight group (1.2 vs. 0.7% of daytime, p <0.001). In both healthy weight and obese children, physical activity levels were exceptionally low, although moderate-to-vigorous-intensity physical activity was significantly lower in the obese group than the healthy weight group. Efforts to prevent and treat obesity in Malaysian children will need a substantial focus on the promotion of reductions in sedentary behaviour and increases in physical activity.
