Abstract:
In lung disease, physical activity improves lung function and reduces morbidity. However, healthy populations are not well studied. We estimate the relationship between spirometric indices and accelerometric physical activity in lung-healthy adolescents. 895 nonsmoking German adolescents without chronic lung disease (45% male, mean± sd age 15.2±0.26 years) from the GINIplus and LISAplus cohorts completed questionnaires, spirometry, 7-day accelerometry and an activity diary. Physical activity was measured as minutes, quintiles and regularity of daily moderate, vigorous and moderate-to-vigorous physical activity (MVPA), participation in sport and active commuting to school. Primary outcomes were forced expiratory volume in 1 s (FEV 1 ), forced vital capacity (FVC), FEV 1 /FVC and forced expiratory flow at 25–75% of FVC; they were separately correlated with physical activity and adjusted for confounders of respiratory function, including early-life exposures. Adolescents averaged 40 min MVPA per day, typical for European youth. 79% participated in sports and 51% commuted actively. An association was suggested between 3% higher FVC (∼100 mL) and either extreme MVPA quintile or percentage of days with 〉 30 min MVPA (p 〈 0.05). However, after Bonferroni correction all associations between spirometry, active lifestyle and physical activity were nonsignificant. Spirometric indices were not significantly associated with active lifestyle or measures of activity in lung-healthy adolescents after adjustment for confounding and multiple-comparison artefacts.
