摘要:We examined the associations between victimization, missed school because of feeling unsafe, and asthma episodes among US high-school students using the 2003 Youth Risk Behavior Survey. Cross-sectional analyses on adolescents with asthma (n=1943) showed that any victimization and missed school because of feeling unsafe significantly increased the odds of having an asthma episode in the past year (adjusted odds ratio [OR]=1.45; 95% confidence interval [CI] = 1.07, 1.95 and adjusted OR = 2.93; 95% CI = 1.90, 4.53, respectively). Victimization and feeling unsafe are important but poorly understood risk factors for asthma. Nine million children and adolescents (12%) younger than 18 years have ever received a diagnosis of asthma 1 ; therefore, asthma prevention is an important public health priority in the United States. The rising trends in asthma prevalence among children and youths 2 who live in urban settings have recently been attributed in part to exposure to community stressors such as violence. 3 , 4 A recent study found a link between exposure to violence and asthma morbidity in children 5 to 12 years of age who live in urban settings. 3 In that study, increased exposure to violence significantly predicted higher number of days with asthma-related symptoms in the child. Other reports also have found that mental health and behavior problems increase asthma morbidity among children living in inner cities. 5 We examined whether victimization and having missed school because of feeling unsafe were associated with having an asthma episode; we used data from a nationally representative sample of US high-school students from 3 different metropolitan settings (urban, suburban, and rural).
