Abstract
Background About 40% of adult Americans use complementary or alternative medicine (CAM) for health problems. Objective To determine the prevalence of reported use of CAM in a population of urban adolescents with asthma. Design/Methods We used a multistaged, stratified sample approach at an inner-city high school. An asthma screening survey was administered to 3800 registered students, aged 13 to 18 years. We identified a subset of 200 respondents who answered yes to each of the following questions: (1) Does your physician think that you have asthma? (2) Do your parents think that you have asthma? (3) Do you think that you have asthma? A self-completion questionnaire was administered to a sample drawn from this cohort. Differences in proportion were tested by χ2analyses. Results Of the 160 participants, 63% were female, 68% were Hispanic, 26% were African American, 33% had weekly symptoms, and 14% had daily symptoms. Overall, 80% of participants reported using CAM for asthma. The most commonly reported CAM included rubs (74%), herbal teas (39%), prayer (37%), massage (36%), and Jarabe 7 syrup (24%). Subjects with daily or weekly symptoms were more likely to use CAM for each episode of asthma (72% vs 51%;P= .005). The 61% of subjects who had a family member who used CAM were more likely to use CAM again (84% vs 39%;P<.001). Of the respondents, 59% reported that CAM was effective. Subjects who perceived CAM to be effective were more likely to use it again (96% vs 22%;P<.001). Conclusions Most adolescents with asthma in this study used CAM. The prevalence of CAM use in this study population was twice the national average for adults.
