Disparities in pediatric asthma exist in that Latino children have higher prevalence and greater morbidity from asthma than non-Latino white children. The factors behind these disparities are poorly understood, but ethnic-related variations in children's ability to accurately recognize and report their pulmonary functioning may be a contributing process.
To determine (1) if differences exist between Latino and non-Latino white children's perceptual accuracy and (2) whether these differences are related to asthma outcomes.
Five hundred and twelve children, aged 7-16 years (290 island Puerto Ricans, 115 Rhode Island Latinos, and 107 Rhode Island non-Latino white children) participated in a 5-week home-based protocol in which twice daily they entered subjective estimates of their peak expiratory flow rate into a hand-held, programmable spirometer and then performed spirometry. Their accuracy was summarized as three perceptual accuracy scores. Demographic data, asthma severity, intelligence, emotional expression, and general symptom-reporting tendencies were assessed and covaried in analyses of the relationship of perceptual accuracy to asthma morbidity and health care use.
Younger age, female sex, lower intelligence, and poverty were associated with lower pulmonary function perception scores. Island Puerto Rican children had the lowest accuracy and highest magnification scores, followed by Rhode Island Latinos; both differed significantly from non-Latino white children. Perceptual accuracy scores were associated with most indices of asthma morbidity.
Controlling for other predictive variables, ethnicity was related to pulmonary function perception ability, as Latino children were less accurate than non-Latino white children. This difference in perceptual ability may contribute to recognized asthma disparities.
拉丁裔儿童的哮喘患病率和发病率高于非拉丁裔白种儿童，这表明在儿科哮喘中存在差异。造成这些差异的原因尚不清楚，但儿童准确识别和报告肺部功能的能力存在种族差异，这可能是一个促成因素。
确定（1）拉丁裔和非拉丁裔白种儿童的知觉准确性是否存在差异，以及（2）这些差异是否与哮喘结局有关。
512 名 7-16 岁的儿童（290 名波多黎各岛裔、115 名罗德岛拉丁裔和 107 名罗德岛非拉丁裔白种儿童）参与了一项为期 5 周的家庭方案，他们每天两次将自己的呼气峰值流速的主观估计值输入到手持可编程肺活量计中，然后进行肺活量计检查。他们的准确性总结为三个知觉准确性得分。评估了人口统计学数据、哮喘严重程度、智力、情绪表达以及一般症状报告倾向，并在分析知觉准确性与哮喘发病率和医疗保健使用的关系时对这些因素进行了协方差处理。
年龄较小、女性、智力较低和贫困与较低的肺功能感知评分相关。波多黎各岛裔儿童的准确性最低，放大分数最高，其次是罗德岛拉丁裔儿童；这两个群体与非拉丁裔白种儿童的差异均有统计学意义。知觉准确性评分与哮喘发病率的大多数指标相关。
在控制其他预测变量的情况下，种族与肺功能感知能力有关，拉丁裔儿童的感知能力不如非拉丁裔白种儿童准确。这种感知能力的差异可能导致了公认的哮喘差异。
