PURPOSE OF THE STUDY.
To determine the association of eczema, asthma, and hay fever with sedentary behavior, including television and/or video game usage, sports participation, and days of vigorous physical activity. The authors of the study also sought to determine if sleep disturbances modify these associations.
The study included 133 107 children aged 6 to 17 years enrolled in the 2003–2004 and 2007–2008 National Survey of Children’s Health.
Data from 2 cross-sectional studies were analyzed by using bivariate and multivariate logistic regression models to look for associations between eczema, hay fever, and asthma and vigorous physical activity, television and/or video game use, and sports participation. Furthermore, the authors conducted a subanalysis on the findings, examining the effect of caregiver-reported disease severity and sleep disturbances. Analysis in multivariate logistic regression models was controlled for sociodemographic factors such as age, sex, race, household income, highest level of parent education, insurance coverage, and place of birth (United States versus a foreign location).
Atopic disease alone was not consistently associated with a specific pattern of vigorous physical activity level or sedentary behavior. However, children with an atopic disease who also had sleep disturbances had significantly higher odds of screen time and lower odds of sports participation than children with either an atopic disease or sleep disturbances alone. Children with a lifetime history of asthma showed decreased odds of ≥1 days of vigorous physical activity (adjusted odds ratio [aOR]: 0.87; 95% confidence interval [CI]: 0.77–0.99) and decreased odds of sports participation (aOR: 0.91; 95% CI: 0.84–0.99). Moderate (aOR: 0.76; 95% CI: 0.57–0.99) and severe eczema (aOR: 0.45; 95% CI: 0.28–0.73), severe asthma (aOR: 0.47; 95% CI: 0.25–0.89), and hay fever (aOR: 0.53; 95% CI: 0.36–0.61) were associated with decreased sports participation in the past year. Severe eczema (aOR: 0.39; 95% CI: 0.19–0.78), asthma (aOR: 0.29; 95% CI: 0.14–0.61), and hay fever (aOR: 0.48; 95% CI: 0.24–0.97) were all associated with decreased odds of ≥1 days of vigorous physical activity.
Children with a severe atopic disease, especially when accompanied by sleep disturbances, were at a higher risk for sedentary behavior.
This is an interesting study with a large, nationally representative sample size from the National Survey of Children’s Health populations. The sample included children across a wide spectrum of ages and of various socioeconomic backgrounds. The findings have important public health and social implications. As the authors of the study noted, this is an association study, and no causation conclusions can be affirmed by the findings. The authors of future studies should focus on atopic disease control and its effect on sedentary behavior and physical activity. Because an association between sedentary behaviors and severe atopic diseases and sleep disturbances was found, further exploration of the effects of sedentary life on cardiovascular comorbidities in atopic patients should be considered.
