孕妇妊娠晚期疲乏特征的潜在类别分析

目的 探讨孕妇妊娠晚期疲乏特征的潜在类别,比较不同类别孕妇在人口学特征及睡眠质量、心理韧性上的差异。方法 于2022年4—7月便利选取郑州市某三级甲等医院产科门诊就诊的251例孕妇为研究对象,采用一般资料调查表、疲劳自评量表、匹兹堡睡眠质量指数量表及心理韧性量表进行调查。结果 孕妇妊娠晚期疲乏特征可分为2个潜在类别,即高情境性-广泛疲乏型（29.08%）和积极情境性-疲乏低发型（70.92%）;Logistic回归分析结果显示：孕周、不良妊娠史、睡眠质量及心理韧性是孕妇妊娠晚期疲乏特征的潜在类别的影响因素（P<0.05）。结论 孕妇妊娠晚期疲乏特征存在群体异质性,可分为2个潜在类别,妊娠周数较大、既往有不良妊娠史、睡眠质量差的孕妇妊娠晚期疲乏症状较重,应对该类别孕妇给予更多关注。

Latent Class Analysis of Fatigue of Pregnant Women in Late Pregnancy

Objective To explore the latent classes of maternal fatigue in the third trimester of pregnancy, and to analyze the differences in demographic characteristics, sleep quality and psychological resilience among different classes. Methods With convenience sampling, 251 pregnant women were recruited from a tertiary grade-A hospital in Zhengzhou from April to July in 2022, and were investigated using general information questionnaire, Fatigue Self-assessment Scale, Pittsburgh Sleep Quality Index and Connor-Davidson Resilience Scale. Results Maternal fatigue in the third trimester of pregnancy could be divided into 2 latent classes: extensive fatigue group with high situational sensitivity (29.08%) and low fatigue group with positive situational sensitivity (70.92%). Logistic regression analysis showed that gestational age, adverse pregnancy history, sleep quality and mental resilience were the influencing factors of latent classes of maternal fatigue in late pregnancy (P<0.05). Conclusion Maternal fatigue in late pregnancy is heterogeneous and can be divided into 2 latent classes. Women with larger gestational weeks, previous adverse pregnancy history and poor sleep quality have more severe symptoms of fatigue in late pregnancy, and need more attention.
