Longitudinal changes in physical activity in a biracial cohort during adolescence

Abstract

The longitudinal data on physical activity collected in the NGHS cohort further confirm a dramatic decrease in the overall level of physical activity during the transition from childhood to adolescence. The consistency among the three methods indicate that both the AD and HAQ are useful tools for the assessment of activity levels in adolescent girls.

Quality of Life and Health Outcomes in Overweight and Non-Overweight Children With Asthma

“…Overall, the data showed a dramatic decrease in the level of physical activity during the transition from childhood to adolescence (Kimm et al, 2000). The results showed that the level of girls' daily activity declined by 35% from ages 9-10 to 18-19 years, whereas the level of habitual activity declined by 83% (Kimm et al, 2000).…”

“…Of additional concern is the age-related decline in physical activity from childhood to adolescence, especially among females (Bradley, McMurray, Harrell, & Deng, 2000;Eaton et al, 2006;Gordon-Larsen et al, 2000;Grunbaum et al, 2004;Harrell et al, 1997;Kimm et al, 2000). Results from the 2005 national Youth Risk…”

“…In a similar study involving only girls, changes in physical activity of 2379 subjects starting from ages 9-10 were studied over a 10 year period (Kimm et al, 2000).…”

“…Recent studies have found that African-American and Hispanic children and adolescents participate in fewer vigorous activities and/or more sedentary activities than Whites, with differences noted as early as elementary school (Bradley et al, 2000;Eaton et al, 2006;Gordon-Larsen et al, 2000;Grunbaum et al, 2004;Kimm et al, 2000). Results from the 1996 National Longitudinal Study of Adolescent Health consisting of a study population of over 17,000 adolescents enrolled in US middle and high schools found that moderate to vigorous physical activity was lower and inactivity higher for non-Hispanic black and Hispanic adolescents (Gordon-Larsen et al, 2000).…”

Dietary risk factors for the development of insulin resistance in adolescent girls: a 3-year prospective study

“…Assessment of physical activity, developmental status and other demographic variables Habitual physical activity was assessed using a 3 d activity diary, in tandem with the 3 d food record (29) . Mean energy expenditure was represented as the number of minutes engaged in different metabolic equivalent (MET) activities across the day, expressed as MET-min/d.…”
