目的：通过对妊娠早期症状与经前期症状之间的相关性分析，评估经前期症状对妊娠早期症状的预测价值。方法对2014年9～12月在郑州大学第一附属医院产科就诊的305例妊娠期妇女进行问卷调查，采用配对t检验对经前期症状和妊娠早期症状进行差异性分析，分别采用简单线性回归模型、多重线性回归模型对经前期症状与妊娠早期症状进行相关性分析。结果妊娠早期症状出现的频数及严重程度与经前期症状比较，差异均有统计学意义（ t＝6.9、t＝6.7， P＜0.001）；妊娠早期与经前期各症状平均严重程度之间存在大量的相关性；妊娠早期症状的总体严重程度与经前期症状的总体严重程度呈显著性相关（b＝0.4，95％CI＝0.3～0.5， P＜0.001）。结论妊娠早期与经前期具有相似的症状模式，妊娠早期出现的某一精神心理症状可通过经前期症状预测，经前期易怒症状的严重程度是预测妊娠早期症状总体严重程度的最佳指标。%Objective Based on the correlation analysis between premenstrual and early pregnancy symptoms , to assess the predictive value of premenstrual symptoms for early pregnancy symptoms .Methods A total of 305 pregnancy women who treated in the Obstetrical department of the first affiliated Hospital of Zhengzhou University from September to December 2014 completed the questionnaire .Paired-sample test was used to test differences between premenstrual symptoms and early pregnancy symptoms .Linear regression analyses and multiple linear regression analyses were used to analyze correlation between premenstrual symptoms and symptoms in early pregnancy .Results Differences of frequency and severity between premenstrual and early pregnancy symptoms were significant (t=6.9、t=6.7, P<0.001);there were a lot of correlations between premenstrual and early pregnancy symptoms ;the global severities of symptoms in premenstrual phase and early pregnancy were significantly associated ( b=0.4, 95% CI=0.3-0.5;P<0.001).Conclusion There were similar symptoms between early pregnancy and premenstrual phase , pregnancy psychologic symptoms could be predicted by premenstrual symptoms , the severity of premenstrual irritability is the best predictor of global severity of early pregnancy symptoms .
