RESUMO
Objective:To investigate the relationships of expectation gap of postpartum support with perceived stress and postpartum depression, and the mediating role of the former in the association between the latter two.Methods:A total of 278 convenient sample of puerperas at 6-8 weeks after delivery from June to August in 2019 in Shenzhen Hospital of Southern Medical University were investigated with the Perceived Stress Scale, the Chinese version of the Postpartum Social Support Questionnaire, and the Edinburgh Postnatal Depression Scale. Structure equation model was established and Bootstrap method was used to explore the direct and indirect effects of these variables.Results:The perceived stress score, and expectation gap of postpartum support score were (26.50±2.50), (25.30±5.79), respectively; and the postpartum depression score was (14.60±2.10). The incidence of postpartum depression(defined as postpartum depression score ≥10) was 37.4%(104/278). Path analysis showed that the model was well fitted (χ 2/ df was 0.265, Tucker-Lewis index was 1.0, comparative fit index was 1.0,root mean square of approximate error was 0, root mean square of standard deviation and residual error was 0.04). Perceived stress positively correlated with expectation gap of postpartum support, and postpartum depression ( P<0.05). Expectation gap of postpartum support positively correlated with postpartum depression ( P<0.05). The effect of perceived stress on postpartum depression was partially mediated by expectation gap of postpartum support (Estimate was 0.285, 95% CI 0.197-0.352). Conclusions:Perceived stress had direct or indirect effect via expectation gap of postpartum support on postpartum depression. This indicated that the medical staff can build a comprehensive support system, reduce the experience of perceived stress among puerperas, improve social support satisfaction, and thus reduce the incidence of postpartum depression.
RESUMO
BACKGROUND/OBJECTIVES: The purpose of this study is to utilize an extended Theory of Planned Behavior in identifying predictors of exclusive breastfeeding intention and behavior among women in Kelantan, Malaysia. SUBJECTS/METHODS: A prospective cohort study was conducted, recruiting pregnant womenthrough two-stage cluster sampling. Their exclusive breastfeeding intention, attitude, perceived norm, perceived behavioral control and past behavior were obtained at baseline through interviewer-guided questionnaire. At one month after delivery, another interview was conducted to determine the two additional variables in the extended theory, which were their postpartum support and breastfeeding difficulty. The behavior, which was the actual duration of exclusive breastfeeding, was obtained from the second follow-up at six months. Pearson correlation and two hierarchical regression analyses were conducted. RESULTS: A total of 200 women completed the study follow-up. Their median intended exclusive breastfeeding duration was 4.0 (IQR 5) months, and the median actual duration was 1.0 (IQR 4) month. The Theory of Planned Behavior explained 51.0% of the variance in intention, with perceived behavioral control and attitude were the significant predictors. It also explained 10.0% of the variance in behavior, but the addition of postpartum support and breastfeeding difficulty increased the amount of explained variance in behavior by 6.0%. The significant predictors of exclusive breastfeeding behavior were intention, postpartum support and breastfeeding difficulty. CONCLUSION: The extended Theory of Planned Behaviorhad a good predictive ability in explaining exclusive breastfeedingintention and behavior. The women's intention to practice exclusive breastfeeding may be improved by improving their perceived behavioral control and attitude. Providing correct postpartum support and skills to handle breastfeeding difficulties after delivery will improve their exclusive breastfeeding behavior.
