AB Introduction: There are some evidences that suggest that regular physical activity reduces the risk of exacerbations in asthma, regardless of the asthma severity and other factors. The aim of this paper is to measure the association between physical activity levels in asthma exacerbations, adjusted by FEV1, age and body mass index (BMI).Methodology: This is a multicenter transversal study where has been included a population of asthmatics of Pneumology consultations of two hospitals in Vizcaya. It has been included patients with previous diagnosis of asthma and monitored by the pneumologist at least for a year, aged between 18 and 70. We used the International Physical Activity Questionnaire (IPAQ). We performed a multivariate logistic regression analysis to determine predictors of exacerbations.Results: We studied 354 patients (54% men). 115 of these (32%) were younger than 32, 123 (35%) between 32 and 55 and 116 (33%) over 55 years. 250 patients (75%) had a BMI below 30. 63 patients (18%) had had asthma exacerbations during the past 6 months. 15 patients (4%) had a FEV1 value below 60%, 39 (11%) between 60 and 80%, and 300 (85%) greater than 80%. Physical activity was divided into quartiles, including 88 (24.8%) in the first quartile, 92 (25.7%) in the second, 54 (23.7%) in the third and 89 (25.1%) in the fourth.Conclusions: Patients with asthma with increased physical activity had a reduced number of exacerbations.
