Abstract

PURPOSE: Western New York (Lin et al., 2005; Lin et al., 2002) and the City of Buffalo residents have high asthma prevalence and health care utilization rates for asthma (Lwebuga-Mukasa et al, 2004; Lwebuga-Mukasa & Dunn-Georgiou, 2002). To date there has been no information regarding asthma incidence among this population. The purpose of this study was to determine the crude asthma incidence rate among children.

METHODS: A cross-sectional study design was used. An 18-item survey including demographic information, asthma diagnosis, asthma symptoms, health care utilization and household triggers were included. The survey was completed on behalf of the child by the primary caregiver. Crude incidence was defined as the percentage of new cases of asthma diagnosed by a physician in the past 12 months over the total number of children without previously diagnosed asthma.

RESULTS: There were 5427 children ages 4 to 14 years, mean 7.6 ± 2.7 included in the analysis. Of the children, 38% were African American, 24% Caucasian, 24% Latino/Hispanic, and 14% other race/ethnicity; 49% were males. The overall crude asthma incidence was 8.2%. There was a 22.3% overall asthma prevalence. Latino/Hispanics had the highest crude asthma incidence, 14.0% compared to 6% for African Americans, 6.7% for Caucasians and 6.8% for other race (x2=63.03, df=3, p=.00). A logistic regression analysis indicated that the reported presence of allergy symptoms (B=2.8, S.E.=.13, p=.00), cockroaches in the home (B=.59, S.E.=.25, p=.02), being of Latino/Hispanic decent (B=.775, S.E.=.14, p=.00), and having a mother with diagnosed asthma (B=.58, S.E.=.15, p=.00), were most strongly associated with newly diagnosed asthma. Pets in the home, mice/rat infestations, home environmental tobacco smoke exposure and carpeting were not statistically significant in the model.

CONCLUSION: Latino/Hispanic children residing in the City of Buffalo have a high crude asthma incidence rate.

CLINICAL IMPLICATIONS: A prospective cohort study investigating the genetic, behavioral, and environmental factors that directly contribute to the clinical onset of asthma is needed.
