- BACKGROUND: Little is known about the joint effects of maternal asthma and maternal depression on childhood asthma. OBJECTIVE: To examine whether maternal depression and maternal asthma lead to greater risk of childhood asthma than maternal asthma alone. METHODS: Cross-sectional studies of children (6-14 years old) in San Juan, Puerto Rico (n = 655) and Sweden (n = 6,887) were conducted. In Puerto Rico, maternal depressive symptoms were defined using the Center for Epidemiologic Studies Depression Scale (CES-D) questionnaire. In Sweden, maternal physician-diagnosed depression was derived from national registries, and maternal depressive symptoms were defined using an abbreviated CES-D questionnaire. Childhood asthma was defined as physician-diagnosed asthma plus current wheeze (in Puerto Rico) or plus medication use (in Sweden). Logistic regression was used for multivariable analysis. RESULTS: Compared with Puerto Rican children whose mothers had neither asthma nor depressive symptoms, those whose mothers had asthma but no depressive symptoms had 3.2 times increased odds of asthma (95% confidence interval [CI] = 2.1-4.8) and those whose mothers had asthma and depressive symptoms had 6.5 times increased odds of asthma (95% CI = 3.3-13.0). Similar results were obtained for maternal depression and maternal asthma in the Swedish cohort (odds ratio for maternal asthma without maternal depression = 2.8, 95% CI = 2.1-3.7; odds ratio for maternal asthma and maternal depression = 4.0, 95% CI = 1.7-9.6). Although the estimated effect of maternal asthma on childhood asthma was increased when maternal depressive symptoms (Puerto Rico) or maternal depression (Sweden) was present, there were no statistically significant additive interactions. CONCLUSION: Maternal depression can further increase the risk of asthma in children whose mothers have a history of asthma.

- In asthma, a substantial impact of disease is on quality of life rather than survival. To date, the quality of life effects of asthma have not been quantitated. The purpose of this study was to quantitate the quality of life effects of asthma via measurement of the health utility of asthmatic patients, and the willingness to pay for an asthma cure. A second goal was to analyze how these measures are related to the different dimensions of quality of life as measured by general and disease specific quality of life instruments. Health utilities were measured on a scale between 0 and 1 using the rating scale, time trade off, and standard gamble methods. Willingness to pay was elicited using both the dichotomous choice and the bidding game approach. Quality of life was assessed using both a generic instrument (the SF-36) and a disease-specific instrument (the Asthma TyPE). Sixty-nine patients with asthma were surveyed. The mean health utility was 0.68 with the rating scale method, 0.89 with the time trade off, and 0.91 with the standard gamble. On average, patients were willing to pay between $200 to $350 dollars more per month for an asthma cure. Nearly all correlations between dimensions of quality of life, health state utilities, and willingness to pay were in the expected direction. The two quality of life instruments performed about equally well in terms of being correlated with and being able to explain the responses to the health state utility questions and the willingness to pay questions. Correlations between the dimensions of the Asthma TyPE and the SF-36 were also fairly high. Further work should focus on validating and refining the different methods of quantitating quality of life for asthma patients.
