摘要 目的采用不同的方法研究孕前体质指数(BMI)与孕期体质量增加的关系,以了解根据孕前BMI制定孕期体质量增加适宜值范围的临床价值。方法收集2018年1月—2019年12月在该院产科进行正规产前检查并分娩的孕妇3933例,用双变量相关性分析法、分组分析法及偏相关分析法分析孕前BMI与孕期体质量增加的关系。结果双变量相关性分析法显示,孕妇孕前BMI与孕期体质量增加的相关系数为-0.064,两者之间有高度相关性(P<0.05);分组分析法结果显示,相同孕前BMI组随身高的不同孕期体质量增加明显不同,孕期体质量增加随身高的增高而增加,且两组间比较差异有统计学意义(P<0.05);偏相关分析法显示,控制身高及孕前体质量因素的影响后,孕前BMI与孕期体质量增加无相关性(P>0.05)。结论孕前BMI与孕期体质量增加的相关性受身高和孕前体质量的影响,结合身高和孕前体质量探讨孕前BMI预测孕期体质量增加的临床价值更大。
