Paed Asthma – Weight loss

Evidence Summary
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.


Conclusion
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.
