研究目的：探讨成人哮喘症状的患病率与居住地剥夺的关系。设计：1991-1993年间进行的两项互补调查，得出新西兰各地成人哮喘症状的患病率。贫困是用NZDep91小区域贫困指数来衡量的。环境：新西兰。研究对象：随机抽取25,042名20-50岁的成年人作为研究对象。主要结果：在控制了年龄、性别和种族可能的混杂因素后，在这个具有代表性的新西兰成年人样本中，12个月期间哮喘的患病率在三个最贫困地区类别中显著高于最不贫困地区类别(第十)。最贫困组与最低贫困组的患病率比为1.29，95%可信区间为1.14、1.47。哮喘患病率随着面积剥夺的增加呈线性增加(x~2(1)=32.2，p<；0.001)。单独来看，毛利人的这一比率也是其他受访者的1.41倍(95%可信区间1.29，1.54)，太平洋岛国人群的比率是其余受访者(主要是欧洲人)的1.29倍(95%可信区间1.10，1.52)。结论：成人哮喘和区域剥夺之间的关系不太可能归因于研究偏差或混淆。进一步的工作应该研究可改变的剥夺因素在这种关系中的可能作用。
STUDY OBJECTIVE: To investigate the relation between the prevalence of asthma symptoms in adults and deprivation in the area of residence. DESIGN: Two complementary surveys carried out between 1991-1993 yielding adult asthma symptom prevalence throughout New Zealand. Deprivation is measured by the NZDep91 index of deprivation for small areas. SETTING: New Zealand. PARTICIPANTS: A random sample of 25,042 adults aged 20-50 years. MAIN RESULTS: After controlling for possible confounding by age, gender, and ethnicity, the 12 month period prevalence rates of asthma in this representative sample of New Zealand adults are significantly higher in the three most deprived area categories than in the least deprived (tenth) category. The prevalence ratio for the most deprived category compared with the least deprived category is 1.29 with 95% confidence intervals (CI) 1.14, 1.47. There is a linear increase in asthma prevalence with increasing area deprivation (chi 2(1) = 32.20, p < 0.001). Independently, the rates are also 1.41 (95% CI 1.29, 1.54) times higher among Maori and 1.29 (95% CI 1.10, 1.52) times higher among the Pacific Island group than among the remaining, mostly European, respondents. CONCLUSIONS: The relation between asthma in adults and area deprivation is unlikely to be attributable to study biases or confounding. Further work should examine the possible role of modifiable deprivation factors in this relation.
