Extract

Scientists have long suspected an association between overweight and asthma to be likely.14 The common assumption is that weight gain occurs because many asthmatic patients avoid exercise since physical activity can trigger their symptoms. The term overweight was defined as a body mass index (BMI) of 25 to 29.9 kg/m2, while obesity was defined as a BMI of ≥ 30 kg/m2.,2 Interestingly, during the last 3 decades the incidences of both obesity and asthma have shown a steady raise, with the incidence of asthma more than tripling during that period. Currently, it is estimated that 97 million adults in the United States are overweight or obese and that 5.3% of US adults are affected by asthma.2 In addition to asthma, obesity substantially raises the risk of morbidity from other diseases such as hypertension, type 2 diabetes mellitus, coronary heart disease, stroke, sleep apnea, and respiratory problems.2
