目的：研究社区环境的变化是否与费城早产(PTB)结局和分娩时胎龄(GA)相关，并确定当考虑相关的个体水平变量时，这些关联是否可能持续。研究设计：我们分析了为单胎妊娠早产的前瞻性队列研究收集的个体水平数据。我们将数据块组级别的数据合并到每个人的家庭地址。进行未经调整的分析，以确定区组变量和个体水平结果之间的关联。被确认为潜在危险因素的区组变量被纳入多变量个体水平模型以确定显著性。结果：我们分析了817名女性的数据。肺结核的患病率
OBJECTIVE: To examine whether variation in neighborhood context isassociated with preterm birth (PTB) outcomes and gestational age(GA) at delivery in Philadelphia, and to determine whether these associations might persist when considering relevant individual-level variables.STUDY DESIGN: We analyzed individual-level data collected for a prospective cohort study of singleton pregnancies with preterm labor. We merged block-group level data to each individual's home address. Unadjusted analyses were performed to determine the association between block-group variables and individual-level outcomes. Block-group variables identified as potential risk factors were incorporated into multivariable individual-level models to determine significance.RESULTS: We analyzed data for 817 women. The prevalence of PTB
