This cross-sectional study examines parents' perceptions of their neighborhoods and general and respiratory health among low-income Chicago families. Asthma disproportionately affects nonwhite, urban, and low socioeconomic status (SES) populations, but Chicago's burden, and the national epidemic, are not well explained by known risk factors. Urban dwellers experience acute and chronic stressors that produce psychological distress and are hypothesized to impact health through biological and behavioral pathways. Identifying factors that covary with lower SES and minority-group status-e.g., stress-is important for understanding asthma's social patterning.
We used survey data from 319 parents of children 5-13 years with asthma/respiratory problems and principal components analysis to create exposure variables representing parents' perceptions of two aspects of neighborhoods: collective efficacy ("CE") and physical/social order ("order"). Adjusted binomial regression models estimated risk differences (RDs) and 95% confidence intervals (CIs) for eight binary outcomes.
Magnitude was generally as expected, i.e., RD for low- versus high- (most favorable) exposure groups (RD(low v. high)) was larger than for the middle versus high contrast (RD(mid v. high)). "Parent general health" was strongly associated with "CE" (RD(low v. high) = 20.8 [95% CI: 7.8, 33.9]) and "order" (RD(mid v. high) = 11.4 [95% CI: 2.1, 20.7]), unlike "child general health," which had nearly null associations. Among respiratory outcomes, only "waking at night" was strongly associated with "CE" (RD(low v. high) = 16.7 [95% CI: 2.8, 30.6]) and "order" (RD(low v. high) = 22.2 [95% CI: 8.6, 35.8]). "Exercise intolerance" (RD(low v. high) = 15.8 [95% CI: 2.1, 29.5]) and "controllability" (RD(mid v. high) = 12.0 [95% CI: 1.8, 22.3]) were moderately associated with "order" but not with "CE," whereas "school absences," "rescue medication use," and "unplanned visits" had nearly null associations with both exposures.
More negative perceptions tended to be associated with higher risk of undesirable outcomes, adding to evidence that the social environment contributes to health and supporting research on stress' health impact among disadvantaged populations. Interventions must address not only traditional "environmental" factors, but also individuals' reactions to stress and attempt to mitigate effects of stressors while structural solutions to health inequities are sought.
本横断面研究调查了芝加哥低收入家庭中父母对其社区的看法以及他们的总体健康状况和呼吸系统健康状况。哮喘对非白人、城市居民和社会经济地位较低(SES)人群的影响尤为严重,但已知的风险因素并不能很好地解释芝加哥以及全国范围内哮喘的负担情况。城市居民会经历急性和慢性应激源,这些应激源会导致心理困扰,并被认为会通过生物和行为途径影响健康。识别与较低的社会经济地位和少数群体身份相关的因素,如压力,对于理解哮喘的社会模式很重要。
我们使用了来自319名5至13岁患有哮喘/呼吸问题儿童的父母的调查数据,并通过主成分分析创建了代表父母对社区两个方面看法的暴露变量:集体效能(“CE”)和物理/社会秩序(“秩序”)。调整后的二项式回归模型估计了八个二元结局的风险差异(RDs)和95%置信区间(CIs)。
效应大小总体上符合预期,即低暴露组与高暴露组(最有利)之间的风险差异(RD(低对高))大于中暴露组与高暴露组之间的差异(RD(中对高))。“父母总体健康”与“CE”(RD(低对高)=20.8 [95% CI:7.8,33.9])和“秩序”(RD(中对高)=11.4 [95% CI:2.1,20.7])密切相关,而“儿童总体健康”的关联几乎为零。在呼吸结局中,只有“夜间醒来”与“CE”(RD(低对高)=16.7 [95% CI:2.8,30.6])和“秩序”(RD(低对高)=22.2 [95% CI:8.6,35.8])密切相关。“运动不耐受”(RD(低对高)=15.8 [95% CI:2.1,29.5])和“可控性”(RD(中对高)=12.0 [95% CI:1.8,22.3])与“秩序”中度相关,但与“CE”无关,而“缺课”、“使用急救药物”和“无计划就诊”与这两种暴露的关联几乎为零。
更多负面看法往往与不良结局的较高风险相关,这进一步证明了社会环境对健康有影响,并支持了关于压力对弱势群体健康影响的研究。干预措施不仅必须解决传统的“环境”因素,还必须解决个人对压力的反应,并在寻求解决健康不平等的结构性方案时试图减轻应激源的影响。
