^*Definitions of asthma morbidity: steroid use, use of oral steroids during worse bout of illness; ER visit, treatment in a hospital ER for asthma in the past 12 months; wheeze without a cold, wheezing or whistling in the chest in the absence of a cold (upper respiratory viral infection) in the past 12 months; prolonged illness, a bout of asthma during the past 12 months lasting 1 week or more; overall morbidity, a positive response to any of these indicators.

^†n = Number of women who had these symptoms of asthma morbidity in the previous year of the 325 women who were diagnosed with asthma. Total population was 853 women.

^‡All multivariate models were adjusted for age, race, area poverty, living in inner-city Boston, cockroach allergen sensitization, cat allergen sensitization, and health insurance.
