美国大部分关于哮喘患病率的研究都是在城市地区进行的，很少有人评估农村地区与城市地区居民之间的哮喘患病率。本研究的目的是比较哮喘的患病率在成年人生活在大都市与nonmetropolitan县在Montana.MethodsWe分析了6,846名成年蒙大拿人谁完成了2008年的行为危险因素监测系统调查的数据。我们使用农村-城市连续体代码将受访者的居住县分类为大都市（Metro），非大都市和邻近大都市县（NMA），以及非大都市和不邻近大都市县（NMNA）。我们比较了目前的自我报告哮喘的患病率之间的受访者在3个领域，整体和选定的特点，并进行多变量逻辑回归分析，以确定因素独立相关的目前自我报告asthma.ResultsNo差异，自我报告哮喘的患病率之间的居民麦德龙和NMA或NMNA县，整体或年龄，性别，种族，年的教育，健康保险状况、家庭年收入或身体质量指数。年龄≥ 65岁的受访者（调整后的比值比[AOR]，0.7; 95%置信区间[CI]，0.5-0.9）和男性（AOR，0.6; 95% CI，0.5-0.8）报告当前哮喘的可能性分别低于年轻受访者和女性。肥胖受访者比非肥胖受访者更有可能（AOR，1.9; 95% CI，1.4-2.7）报告哮喘。大都市县居住地与自我报告的当前asthma.ConclusionThe患病率自我报告的当前哮喘是类似的大都市和nonmetropolitan县在蒙大拿州，但存在其他社会人口学差异。我们的研究结果强调需要进行地区和州的哮喘监测，以了解与之相关的人口统计学风险因素，并确定美国哮喘患病率的潜在地理差异。
IntroductionMost US studies on asthma prevalence have been conducted in urban areas, and few have assessed the prevalence of asthma among residents of rural areas versus urban areas. The objective of this study was to compare the prevalence of asthma among adults living in metropolitan versus nonmetropolitan counties in Montana.MethodsWe analyzed data from 6,846 adult Montanans who completed the Behavioral Risk Factor Surveillance System survey in 2008. We used Rural-Urban Continuum Codes to categorize respondents' county of residence as metropolitan (Metro), nonmetropolitan and adjacent to a metropolitan county (NMA), and nonmetropolitan and nonadjacent to a metropolitan county (NMNA). We compared the prevalence of current self-reported asthma among respondents in the 3 areas, overall and by selected characteristics, and conducted multivariable logistic regression analyses to identify factors independently associated with current self-reported asthma.ResultsNo differences in the prevalence of self-reported asthma were found between residents of Metro and NMA or NMNA counties, overall or by age, sex, race, years of education, health insurance status, annual household income, or body mass index. Respondents aged 65 years or older (adjusted odds ratio [AOR], 0.7; 95% confidence interval [CI], 0.5-0.9) and men (AOR, 0.6; 95% CI, 0.5-0.8) were less likely to report current asthma than younger respondents and women, respectively. Obese respondents were more likely (AOR, 1.9; 95% CI, 1.4-2.7) to report asthma than were respondents who were not obese. Metropolitan county of residence was not independently associated with self-reported current asthma.ConclusionThe prevalence of self-reported current asthma is similar in metropolitan and nonmetropolitan counties in Montana, but other sociodemographic differences exist. Our findings highlight the need to conduct regional and state surveillance of asthma to understand the demographic risk factors associated with it and to determine the potential geographic variation of asthma prevalence in the United States.
