Semistructured interviews were conducted with six puerperium women and five primary caregivers.Primary and secondary outcome measures This study used a questionnaire survey to collect and analyse the current postpartum dietary and hygiene behaviours among women in the South China region, along with their influencing factors.Results Multinomial logistics regression revealed women residing in urban-rural fringe were more likely to use ventilated rooms (OR 4.496, 95% CI 2.363 to 8.552) and avoid hair washing (OR 0.345, 95% CI 0.159 to 0.749) compared with urban residents. Additionally, women who practiced Buddhism were more likely to wash their hair (OR 11.070, 95% CI 2.339 to 52.379) and take baths (OR 6.856, 95% CI 2.057 to 22.855) compared with those with no religious affiliation. Lastly, those whose primary caregiver was their husband were more likely to consume watermelon (OR 2.235, 95% CI 1.119 to 4.463), persimmon (OR 4.395, 95% CI 1.886 to 10.242) and longan (OR 2.612, 95% CI 1.362 to 5.010). The qualitative study identified five themes: dietary practices, hygiene habits, personal attitude, sources of information and support.Conclusion The dietary and hygiene behaviours of puerperium women in South China are significantly influenced by the residen, primary caregivers and religious beliefs.
