Methods: We performed a retrospective study of cases with asthma who died of adult from 1995 to 2010. A total of 109, they surveyed the families of 65 for a 59.63% and an equal number of controls. Of all respondents 36 were women (55.39%) and 29 men (44.61%) and an average age of 55.8 years (53.7 for women and 58.4 for men).
Results: Univariate analysis of the level of schooling had a RD = 2.68, the per capita financial <$ 100.00 an RD = 2.32, smoking a RD = 2.76, in cardiovascular disease DR = 2.46 and no care between exacerbations had a RD = 2.43.
The multivariate logistic regression analysis found significant association with a poorly ventilated RD = 7.29, relative risk (RR) of 5.93, lack of sun RD = 4.85 RR = 7.41; pets RD = 2 30, RR = 5.82; smokers RD = 2.76 RR = 14.81; the use of beta2 agonist> 3 teams / RD = 18.4 months RR = 69.93 and the severity of the disease RD = 8 , 80 RR = 23.47.
Conclusions: Inadequate socioeconomic conditions (lack of ventilation, sun and presence of pets and cigarette smoke in households as poor management of the disease (use of beta2 agonist> 3 teams / month) are risk factors for death from asthma. Deaths from asthma were more common outside the hospital in winter.
