Objective

To understand the current situation and influencing factors of lactation mastitis in postpartum females, and to provide useful evidence for the prevention and control of lactation mastitis.

Methods

From January to October 2024, a cohort of pregnant females at 32-42 weeks of gestation was established in a tertiary hospital in Karamay city, and followed up until 42 days postpartum. Among them, 196 females who developed lactation mastitis were selected as the case group, and 196 females who did not develop lactation mastitis were matched 1:1 according to age ± 2 years as the control group. A self-designed questionnaire was used to investigate the basic information of the females. χ2 test and binary logistic regression analysis were used to analyze the influencing factors.

Results

A total of 624 pregnant females were included in this study.During the study period, 196 cases of lactation mastitis occurred, with an incidence rate of 31.41%. Binary logistic regression analysis showed that primiparity (OR=2.086, 95% CI: 1.316-3.307), nipple fissure (OR=3.593, 95% CI: 2.261-5.711),excessive milk production (OR=2.697, 95% CI: 1.393-2.261), family dysfunction (OR=2.435, 95% CI: 1.264-4.691), and co-occurrence of postpartum depression and anxiety (CAD) (OR=2.551, 95% CI: 1.369-4.755) were risk factors for lactation mastitis in postpartum females.

Conclusion

Hospitals and communities should fully play their supportive roles, provide personalized and systematic breastfeeding consultation and guidance for postpartum females and their family members, and emphasize the importance of family support to reduce the occurrence of lactation mastitis in postpartum females and promote breastfeeding.
