International Journal of Physical Activity and Health

Objectives: The increasing rates of physical inactivity and sedentary behaviors among youth are a significant public health concern. The greatest disparities in physical activity (PA) are experienced by underserved (racial/ethnic minority, low-income) youth. This study aimed to characterize accelerometer-measured PA behaviors in a sample of low-income, predominantly Latino, preadolescents. Methods: Participants wore wrist worn GENEActiv accelerometers for 7 days. PA levels were classified as sedentary (< 50 mg), light (50-150 mg), moderate (> 150-500 mg), vigorous (> 500 mg), and MVPA (≥ 150 mg). Time spent in PA levels and sedentary time (ST), prevalence of meeting MVPA guidelines, and PA volume were estimated from accelerometer data. Three-way …

BACKGROUND: Variability exists in children's activity patterns due to the association with environmental, social, demographic, and inter-individual factors. This study described accelerometer assessed physical activity patterns of high and low active children during segmented school week days whilst controlling for potential correlates.

METHODS: Two hundred and twenty-three children (mean age: 10.7 ± 0.3 yrs, 55.6% girls, 18.9% overweight/obese) from 8 north-west England primary schools wore ActiGraph GT1M accelerometers for 7 consecutive days during autumn of 2009. ActiGraph counts were converted to minutes of moderate (MPA), vigorous (VPA) and moderate-to-vigorous (MVPA) physical activity. Children were classified as high active (HIGH) or …
