ABSTRACT
<p><b>OBJECTIVE</b>To investigate the sociopsychological basis of hypertensive disorder in pregnancy (HDP) and explore a new pathway for etiological study of HDP.</p><p><b>METHODS</b>A prospective investigation was conducted in 1154 women in second trimester pregnancy and 9 factors were surveyed using Olson marital quality questionnaire (ENRIC). The discrepancy between the norms and factor scores of ENRIC was analyzed, and the scores of ENRIC were compared between normal gravidas and patients with HDP. The correlation between ENRIC scores and the severity of the condition was also evaluated.</p><p><b>RESULTS</b>The score of the 1124 gravidas for marital satisfaction was significantly higher than the norm (P<0.05), but the scores for relationship with relatives and sexual life were significantly lower (P<0.05). The other 6 factors had similar scores with the norms (P>0.05). Patients with HDP had significantly lower scores for 7 factors than the normal gravidas (P<0.05), but had comparable scores for financial arrangement and sexual life (P>0.05). The severity of HDP was not found to associate with variation of the scores for the 9 factors (P>0.05).</p><p><b>CONCLUSIONS</b>Marital quality is an important social and psychological basis of HDP, and this study provides some evidence for the social and psychological investigation of the etiology of HDP.</p>
