Factors associated with low Apgar in newborns in birth center

ABSTRACT Objective: to analyze factors associated with Apgar of 5 minutes less than 7 of newborns of women selected for care at the Center for Normal Birth (ANC). Method: a descriptive cross-sectional study with data from 9,135 newborns collected between July 2001 and December 2012. The analysis used absolute and relative frequency frequencies and bivariate analysis using Pearson’s chi-square test or the exact Fisher. Results: fifty-three newborns (0.6%) had Apgar less than 7 in the 5th minute. The multivariate analysis found a positive association between low Apgar and gestational age less than 37 weeks, gestational pathologies and intercurrences in labor. The presence of the companion was a protective factor. Conclusion: the Normal Birth Center is a viable option for newborns of low risk women as long as the protocol for screening low-risk women is followed.

摘要 研究目的：分析在正常分娩中心（ANC）接受助产服务的产妇所分娩新生儿的5分钟阿普加评分（Apgar Score）低于7分的相关影响因素。研究方法：本研究为描述性横断面研究，纳入2001年7月至2012年12月期间收集的9135名新生儿相关数据，数据分析采用绝对频数与相对频数进行描述性统计，并通过皮尔逊卡方检验或费希尔精确检验开展二元分析。研究结果：共有53名新生儿（占比0.6%）的5分钟阿普加评分低于7分。多因素分析显示，低阿普加评分与妊娠时长不足37周、妊娠期并发症及分娩期异常事件存在正相关关联；陪护人员在场则为保护性因素。研究结论：只要严格遵循低危产妇筛查流程，正常分娩中心可作为低危产妇分娩的可行选择。
