CREAL: Interventions on BMI and physical activity reduce the risk of asthma


News from CREAL


Interventions on Body Mass Index (BMI) and physical activity may have a modest impact on the risk of adult-onset asthma. Researchers of CREAL, an ISGlobal alliance research centre, analyzed the incidence of adult-onset asthma after hypothetical interventions in 76,470 US women from the Nurses’ Health Study followed between 1988 and 1998.

During the 10-year follow-up period, 1,146 women (1.5%) developed asthma. The asthma risk was reduced by 4% under the BMI intervention and similar reduction was observed with the physical activity intervention. The joint intervention produced a higher reduction in asthma incidence.
