ABSTRACT The prevalence of asthma among children has been increasing in the United States and it is estimated that there are approximately 5 million children with asthma. This cross-sectional survey sought to estimate the prevalence of asthma and asthma symptoms and potential risk factors among children aged 16 and younger, in a largely rural population in the USA.
This study was a telephone survey of 1500 households in the South Plains/Panhandle region of Texas. Parents of children were interviewed with a response rate of 64%. Having been diagnosed with asthma by a physician and a report of wheezing in the last 12 months were used as dependent variables in multivariate logistic regressions with several sociodemographic and environmental factors as potential confounders.
The age-adjusted prevalence of asthma and wheezing among children were approximately 15 and 18%, respectively. The prevalence of asthma was highest (20%) among children aged 11-16 (P < 0.001). Living in urban areas was associated significantly with asthma and wheezing. Non-Hispanic blacks reported significantly increased odds of asthma in their children (adjusted odds ratio (OR) = 2.04, 95%CI 1.02-4.08), whereas Mexican-Americans reported significantly reduced odds of asthma (adjusted OR = 0.48, 95%CI 0.29-0.78) and wheezing (adjusted OR = 0.58, 95%CI 0.37-0.89) in their children. The odds of asthma (adjusted OR = 1.78, 95%CI 1.09-2.92) and wheezing (adjusted OR = 2.45, 95%CI 1.52-3.95) was highest among children in the highest body mass index quartile. No significant association with pet ownership and exposure to second-hand smoke with asthma and wheezing was observed in this study.
Urban residence, non-Hispanic black and Mexican-American race/ethnicity, and being overweight were significantly associated with the increased risk of asthma and/or wheezing.
