Postpartum depression and partner support during the period of lactation: Correlation research and its influencing factors

BACKGROUND Postpartum depression (PPD) not only affects the psychological and physiological aspects of maternal health but can also affect neonatal growth and development. Partners who are in close contact with parturient women play a key role in communication and emotional support. This study explores the PPD support relationship with partners and its influencing factors, which is believed to establish psychological well-being and improve maternal partner support. AIM To explore the correlation between PPD and partner support during breastfeeding and its influencing factors. METHODS Convenience sampling was used to select lactating women (200 women) who underwent postpartum examinations at the Huzhou Maternity and Child Health Care Hospital from July 2022 to December 2022. A cross-sectional survey was conducted on the basic information (general information questionnaire), depression level [edinburgh postnatal depression scale (EPDS)], and partner support score [dyadic coping inventory (DCI)] of the selected subjects. Pearson's correlation analysis was used to analyze the correlation between PPD and DCI in lactating women. Factors affecting PPD levels during lactation were analyzed using multiple linear regression. RESULTS The total average score of EPDS in 200 lactating women was (9.52 +/- 1.53), and the total average score of DCI was (115.78 +/- 14.90). Dividing the EPDS, the dimension scores were: emotional loss (1.91 +/- 0.52), anxiety (3.84 +/- 1.05), and depression (3.76 +/- 0.96). Each dimension of the DCI was subdivided into: Pressure communication (26.79 +/- 6.71), mutual support (39.76 +/- 9.63), negative support (24.97 +/- 6.68), agent support (6.87 +/- 1.92), and joint support (17.39 +/- 4.19). Pearson's correlation analysis demonstrated that the total mean score and individual dimension scores of EPDS during breastfeeding were inversely correlated with the total score of partner support, stress communication, mutual support, and co-support (P < 0.05). The total mean score of the EPDS and its dimensions were positively correlated with negative support (P < 0.05). Multiple linear regression analysis showed that the main factors affecting PPD during breastfeeding were marital harmony, newborn health, stress communication, mutual support, negative support, co-support, and the total score of partner support (P < 0.05). CONCLUSION PPD during breastfeeding was associated with marital harmony, newborn health, stress communication, mutual support, negative support, joint support, and the total DCI score.
