Objective: To study the correlation between postpartum depression and personality characteristics of elderly parturients. Methods: Enrolled 273 elderly parturients who were admitted to the obstetrics department of Chuzhou People's Hospital, which has established a green channel for treatment with our school, from January to December 2018. They were older than 35 years old, with an average age range of (37.1±1.1)years and a gestational age of 37~ 42 weeks.This study was conducted by questionnaire survey, using the Eysenck Personality Questionnaire (EPQ-RSC), "susceptibility personality characteristics scale, VPSQ" and "Edinburgh Postpartum Depression Scale, EPDS" questionnaire survey. Results: The Edinburgh Postpartum Depression Scale showed that there were 45 parturients with EPDS≥13, with an average score of (16.03±2.83),and the incidence of postpartum depression was 16.48%.Compared with the non-depressed group, the introversion score in the depressed group was significantly decreased, while the neuroticism score was significantly increased ( P<0.05).The susceptibility personality characteristics scale score, the score value of the susceptibility subscale of depressed mothers is (22.14±2.83),which is extremely significantly higher than the score value of (11.24±1.47)of the susceptibility subscale of non-depressed patients( P<0.001).The total r value of EPDS score and VPSQ score is 0.72,which indicates that the susceptible personality characteristics of elderly parturients are positively correlated with postpartum depression. Conclusion: The susceptible personality characteristics of elder parturients are positively correlated with postpartum depression.Therefore,the susceptible personality characteristics of elder parturients can be scored before childbirth to predict the occurrence of postpartum depression early and carry out early intervention to effectively prevent postpartum depression.
