Jago R, et al. - In this analysis of the Avon Longitudinal Study of Parents and Children population-based cohort study, researchers compared the physical activity of adolescents with three common long-term conditions (asthma, eczema and obesity) with adolescents without these conditions. Study participants included 6473 adolescents, ages 12, 14 and 16, with complete accelerometer data at at least one time point. Findings revealed that mean moderate to vigorous intensity physical activity (MVPA) minutes per day did not vary between asthma or eczema adolescents and those without, but obese adolescents engaged in fewer minutes of MVPA. The findings reinforce the need for strategies to help obese adolescents become more active, but suggest that physical activity strategies for adolescents with mild asthma or eczema should not be developed on an individual basis.
