理由：儿童哮喘的差异在于拉丁裔儿童比非拉丁裔白人儿童有更高的患病率和更高的发病率。这些差异背后的因素尚不清楚，但与种族有关的儿童准确识别和报告其肺功能的能力差异可能是一个促成过程。目的：确定(1)拉丁裔和非拉丁裔白人儿童的知觉准确性是否存在差异；(2)这些差异是否与哮喘结局有关。方法：512名7-16岁的儿童（290名波多黎各人，115名罗得岛拉丁裔儿童，107名罗得岛非拉丁裔白人儿童）参加了为期5周的家庭方案，每天两次，他们将主观估计的峰值呼气流量输入手持式可编程肺活量计，然后进行肺活量测定。他们的准确度被总结为三个感知准确度分数。对人口统计数据、哮喘严重程度、智力、情绪表达和一般症状报告倾向进行评估，并对感知准确性与哮喘发病率和医疗保健使用的关系进行协变分析。测量结果和主要结果：年轻、女性、低智力和贫困与肺功能感知评分较低相关。波多黎各岛儿童的准确率最低，放大分数最高，其次是罗德岛拉丁裔；两者都与非拉丁裔白人儿童有显著差异。知觉准确度评分与大多数哮喘发病率指标相关。结论：控制其他预测变量，种族与肺功能感知能力有关，因为拉丁裔儿童的准确性低于非拉丁裔白人儿童。这种感知能力的差异可能导致公认的哮喘差异。
Rationale 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.Objectives: 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.Methods: 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.Measurements and Main Results: 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.Conclusions: 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.
