Asthma, type 2 diabetes and increased BMI are associated

This Danish study examined the relationship between asthma, type 2 diabetes and increased body mass index (BMI) in adult twins.

The risk of asthma was increased in subjects with type 2 diabetes relative to nondiabetic subjects both in men (13.5% vs. 7.5%) and in women (16.6% vs. 9.6%), p value was quite significant at 0.001.

BMI remained a highly significant predictor for asthma independently of diabetes status in women, but not in men.

Asthma, type 2 diabetes and increased BMI are strongly associated in adults, particularly in women. These results may suggest a common aetiology for asthma and metabolic syndrome.

Higher body mass index may decrease response to inhaled corticosteroids in persistent asthma (http://goo.gl/Xt6eP).
