Physical activity intervention studies have been shown to reduce fat mass significantly within asthmatic groups which in turn would lower BMI readings. Studies have shown that as a group, paediatric asthma patients can have a higher body mass index (BMI), rates of central obesity and higher fat mass compared to non-asthmatic populations. Higher rates of central obesity and raised BMI readings have been clearly demonstrated in literature to be associated with a higher frequency of reported asthma symptoms.
Quality of Evidence
Grade A – high quality
Strength of Recommendation
1A. Strong recommendation, statistically significant results from intervention-based studies with no reported harmful effects.
Low levels of physical fitness and activity levels are significantly associated with increased rates of central obesity and raised BMI readings – which have been associated with a more frequent reporting of asthma symptoms. Whether children with asthma are overall significantly less active than non-asthmatic groups is still unclear. However, avoiding sedentary behaviour and encouraging physical activity should be strongly encouraged within this population to prevent obesity and other poor health outcomes.
