目的：探讨哮喘患者自我管理中的数值技能与哮喘相关生活质量（akol）的相关性。方法：成人中重度哮喘患者完成哮喘计算能力问卷（ANQ）、阅读理解能力和自我效能感评估以及哮喘生活质量问卷（miniAQLQ）。在潜在混杂因素（人口统计变量）和中介因素（如收入和自我效能）的背景下，使用相关性检验和多变量模型来评估混杂因素和中介因素，评估计算能力- aqol关系。结果：对80例成人中度或重度哮喘患者进行了评估。平均ANQ评分为2.3 +/- 1.2（范围0-4）。ANQ与miniAQLQ相关（rho = 0.24, p = 0.03）。在控制与AQOL显著相关的潜在混杂因素（年龄、拉丁裔）时，这种关联持续存在（rho = 0.27, p = 0.02）。家庭收入对ANQ-miniAQLQ的关联有中介作用；当调整收入时，相关性降低了81% （rho = 0.05, p = 0.65）。相比之下，自我效能感对这种关联的调节作用较弱；当控制自我效能时，相关性降低了26% （rho = 0.20, p = 0.08）。结论：哮喘自我管理所需的数值技能主要通过对收入的影响影响空气质量，对自我效能感的影响较小。实践意义：成人哮喘患者将受益于自我管理指导，使用最简单的数学结构，其理解被临床医生证实。(C) 2009爱思唯尔爱尔兰有限公司
Objective: To examine the correlation of numerical skills used in patients' self-management of asthma with asthma-related quality of life (AQOL).Methods: Adults with moderate-severe asthma completed the Asthma Numeracy Questionnaire (ANQ), assessments of reading comprehension and self-efficacy, and the mini-Asthma Quality of Life Questionnaire (miniAQLQ). The numeracy-AQOL relationship was evaluated in the context of potential confounders (demographic variables) and mediators (e.g. income and self-efficacy), using tests of correlation then multivariable models to assess for confounders and mediators.Results: 80 adults with moderate or severe asthma were evaluated. Mean ANQ score was 2.3 +/- 1.2 (range 0-4). ANQ was correlated with miniAQLQ (rho = 0.24, p = 0.03). This association was sustained (rho = 0.27, p = 0.02) when controlling for potential confounders significantly associated with AQOL (age, Latina ethnicity). The ANQ-miniAQLQ association was mediated by household income; the correlation was reduced by 81% when adjusting for income (rho = 0.05, p = 0.65). In contrast, self-efficacy less strongly mediated this association; the correlation was reduced by 26% when controlled for self-efficacy (rho = 0.20, p = 0.08).Conclusion: Numerical skills needed for asthma self-management influence AQOL primarily through their impact on income and, to a lesser extent, on self-efficacy.Practice implications: Adults with asthma will benefit from self-management instructions employing the simplest mathematical constructs whose understanding is confirmed by clinicians.
