The purpose of this study is to analyze the influence of sensitivity to cold or hiesho in pregnant Japanese women and to examine the relationship between hiesho and premature labor.
In this retrospective cohort study in Japanese women after delivery, information for the approximately 12 months between October 19, 2009 and October 8, 2010 was obtained using questionnaire surveys and medical records at 6 hospitals with obstetric and pediatric departments in the Greater Tokyo Metropolitan Area. Further, in this analysis, confounding factors were adjusted by performing analysis of covariance and stratified analysis using propensity scores. The Research Ethics Review Committee of St. Luke's College of Nursing (09-057) approved this study.
Analysis of data from 2,810 women was performed. Regarding the correlation between hiesho and premature labor, the incidence of premature labor was 3.38 times higher (analysis of covariance) or 3.47 times higher (stratified analysis) among pregnant women with hiesho than among those without hiesho (P < 0.001). The results of this study proved the existing discussions that there is a correlation between hiesho
during the latter stages of pregnancy and incidence of premature labor.
本研究旨在分析日本孕妇对寒冷或畏寒的敏感性影响，并探讨畏寒与早产之间的关系。
在这项针对日本产后女性的回顾性队列研究中，通过问卷调查和东京大都市区6家设有妇产科和儿科的医院的病历，获取了2009年10月19日至2010年10月8日约12个月期间的信息。此外，在本分析中，通过使用倾向得分进行协方差分析和分层分析来调整混杂因素。圣路加护理学院研究伦理审查委员会（09 - 057）批准了本研究。
对2810名女性的数据进行了分析。关于畏寒与早产之间的相关性，有畏寒的孕妇早产发生率比没有畏寒的孕妇高3.38倍（协方差分析）或3.47倍（分层分析）（P < 0.001）。本研究结果证实了现有关于孕期后期畏寒与早产发生率之间存在相关性的讨论。
孕期后期畏寒与早产发生率之间存在相关性。
