Physical Activity of Asthmatic and Nonasthmatic Children
Questionnaires examining behaviors and attitudes related to physical activity and asthma were administered to 408 urban schoolchildren aged 11-13 years. Asthmatics (16% of the sample) were more frequently active and were more anxious prior to exercise than nonasthmatics, but did not differ significantly from nonasthmatics in enjoyment of exercise or in physical self-concept. The motives for performing exercise or sport were similar in the two groups, although the asthmatics perceived less pressure to be active from parents or school than the nonasthmatics. It is concluded that asthmatic children have favorable behaviors and attitudes in relation to exercise and sport.

Still, various studies point at avoidance of sports and certain daily life activities like walking stairs, even by patients with mild symptoms. We aimed to compare physical activity levels between healthy subjects and asthmatics with controlled and uncontrolled disease. Methods Data on asthma and PA were drawn from the Portuguese National Asthma Survey. The short telephone version of the International Physical Activity Questionnaire (IPAQ) was used to measure PA levels. Current asthma was defined as self-reported asthma and at least one of these criteria: one or more asthma symptoms in the last twelve months, currently taking asthma medication or an asthma medical appointment in the previous twelve months. Controlled asthma was defined as a CARAT global score > 24 or a CARAT second factor score ≤ 16. Healthy subjects were defined as individuals without atopy, heart disease or any respiratory symptom. X2 and Mann–Whitney/Kruskall-Wallis tests were used to compare groups. Logistic regression analyses were performed to assess relations between asthma status and PA dimensions. Results A total of 606 non-asthmatics, 125 controlled and 78 uncontrolled asthmatic subjects were included. In both genders, overall PA level did not differ significantly between groups. Controlled (men) and uncontrolled (women) asthmatics did more vigorous PA than healthy respondents. Male controlled asthmatics also did more moderate PA. Crude logistic regression showed positive relations between daily sitting time, vigorous and moderate PA and controlled asthma in men and between vigorous PA and uncontrolled asthma in women. After adjustments for confounders, moderate PA remained a predictor of controlled asthma in men, while vigorous PA doubled the risk of uncontrolled asthma in women. Conclusion Our study showed that adult asthmatics, independent of asthma control, do not seem to have a more sedentary lifestyle than their peers. Nevertheless, PA should be encouraged, as only about half of them reached activity recommendations.0Comments 10Citations
- "walking stairs), even by patients with mild symptoms, and lower energy expenditures from leisure-time PA and more inactivity in asthma patients than in controls567. However, higher physical activity levels in asthmatics were also found , as well as no differences in overall exercise frequency or duration . Data on activity levels in asthma are thus inconsistent and little is known about differences between asthmatics with controlled and uncontrolled disease . "
[Show abstract] [Hide abstract] ABSTRACT: This review aims to give an overview of available published evidence concerning the association between physical activity and asthma in children, adolescents and adults. We included all original articles in which both physical activity and asthma were assessed in case-control, cross-sectional or longitudinal (cohort) studies. Excluded were studies concerning physical fitness, studies in athletes, therapeutic or rehabilitation intervention studies such as physical training or exercise in asthma patients. Methodological quality of the included articles was assessed according to the Newcastle-Ottawa Scale (NOS). A literature search was performed until June 2011 and resulted in 6,951 publications derived from PubMed and 1,978 publications from EMBASE. In total, 39 studies met the inclusion criteria: 5 longitudinal studies (total number of subjects n = 85,117) with physical activity at baseline as exposure, and asthma incidence as outcome. Thirty-four cross-sectional studies (n = 661,222) were included. Pooling of the longitudinal studies showed that subjects with higher physical activity levels had lower incidence of asthma (odds ratio 0.88 (95% CI: 0.77-1.01)). When restricting pooling to the 4 prospective studies with moderate to good study quality (defined as NOS≥5) the pooled odds ratio only changed slightly (0.87 (95% CI: 0.77-0.99)). In the cross-sectional studies, due to large clinical variability and heterogeneity, further statistical analysis was not possible. The available evidence indicates that physical activity is a possible protective factor against asthma development. The heterogeneity suggests that possible relevant effects remain hidden in critical age periods, sex differences, or extremes of levels of physical activity (e.g. sedentary). Future longitudinal studies should address these issues.0Comments 32Citations

[Show abstract] [Hide abstract] ABSTRACT: Purpose. The purposes of this study were to assess the amount of physical activity children with asthma participate in and to explore the factors which influence their levels of physical activity. Methods. A total of 152 children with asthma, ranging in age from 8 to 11 years, were enrolled in this study. The amount of physical activity for each child was gathered from self-reported 3-day physical activity logs (3d-PAL). Personal, diseased-related, psychological and environmental factors influencing physical activity were gathered from questionnaires completed by children and from parent interviews. Results. Only 32.9% of children with asthma took part in 20 minutes or more of vigorous physical activity (VPA) more than three times per week, much less than the 85% participation rate advised by the Healthy People 2010 objectives. Access to exercise facilities, exercise-induced attack (EIA), and gender were predictors of moderate-to-vigorous physical activity (MVPA) (p < 0.001). Children with more access to exercise facilities (p < 0.01) and fewer episodes of EIA (p < 0.01) were more likely to engage in MVPA; furthermore, boys with asthma participated more in MVPA than girls (p<0.01). Access to team sports was the determinant of VPA (p<0.05). Conclusions. Inactive children with asthma need appropriate exercise prescriptions to increase physical activity. Pediatric practitioners can enhance physical activity by advising parents to improve access for their children to exercise facilities, prescribing appropriate treatment for EIA, and encouraging girls with asthma to be more active.0Comments 1Citation
- "Asthmatic adolescents are usually less active than their non-asthmatic peers with suffering from asthma being given as the reason for lower physical activity, in an asthmatic physical activity review . Similar to our findings, Weston et al. found asthmatic adolescents were significantly more active than non-asthmatic adolescents . Another systematic review has reported that, in many studies, there are no significant differences in physical activity between asthmatic children and non-asthmatic children, and suggested that high physical activity levels may protect against the development of asthma .
