Mediating effects of social support between antenatal depression and fear of childbirth among nulliparous woman.

BACKGROUND
Although gestation and childbirth are progressive physical processes for most pregnant women, there are both physical and great psychosocial challenges throughout the process, which increase the sensitivity and vulnerability of women. Even for women with low-risk pregnancies, it is common to experience degrees of fear, especially for primipara women when faced with childbirth. During their first pregnancy, women may have no relevant health knowledge or experience with delivery and have difficulty identifying prenatal depression and other existing mental health factors; a fear of childbirth (FOC) may engender adverse outcomes for mothers and babies. Social support is a very important influential factor for prenatal depression.


METHODS
This study adopted a descriptive cross-sectional design. The participant cohort involved 609 primipara women (≥18 years old) who had received routine prenatal care and visited a tertiary care hospital in Xi'an. The participants completed structured questionnaires, including the 10-item Edinburgh Postnatal Depression Scale (EPDS), 12-item Multidimensional Scale of Perceived Social Support (MSPSS), and 33-item Wijma Delivery Expectancy/Experience Questionnaire (W-DEQ), alongside contribution of information regarding their demographic characteristics. Descriptive and correlation analyses were adopted to verify the correlations among these variables. Multiple regression models were examined by the SPSS PROCESS procedure with bootstrapping to confirm the significance of the mediation effect.


RESULTS
The widespread prevalence of FOC in healthy pregnant women was 22.3% (WDEQ score ≥85). The mean scores of depression, social support, as well as FOC scores of participants were 9.50 (5.19), 70.91 (9.25), and 70.43 (20.88), respectively. Remarkable correlations were identified between pregnancy depressive symptoms, social support, and FOC. Results presented an indirect effect, indicating that the impacts of antenatal depression on FOC were mediated by social support.


CONCLUSIONS
Perceived social support played a mediating role between antenatal depression and FOC among healthy primipara women. Techniques and suggestions for boosting social support may be expected to have a positive impact on the depressive symptoms of pregnant women with FOC.
