PurposeThis study aimed to clarify the components related to midwifery care for pregnant women's continued self-care for relieving “hiesho” (sensitivity to cold) at birth centers.MethodsIn total, 129 midwives working at birth centers for at least five years, handling deliveries across the country, and who provided support for pregnant women's self-care for relieving hiesho at prenatal checkups were selected for this study. An anonymous self-administered questionnaire survey was conducted. The main method of analysis was an exploratory factor analysis of midwifery care for pregnant women's continued self-care to relieve hiesho. This study was approved by the Ethical Review Committee of Yokohama City University and followed all relevant ethical considerations (approval number: F221000004).ResultsIn total, 95 valid questionnaire survey responses were received (valid response rate 92.2%). The two items that were “always implemented” (response rate of >95%) for midwifery care of pregnant women's continued self-care for relieving hiesho were “Interacting with pregnant women to be aware of the presence of the fetus” and “Interacting with pregnant women so that they can have the desire to give birth on their own.” The four components of midwifery care were as follows: (1) Promoting awareness while understanding pregnant women's thoughts of continuing self-care for hiesho, (2) Motivating pregnant women to start with self-care for hiesho that they can do, (3) Creating opportunities for pregnant women to access information about self-care for hiesho themselves, and (4) Sharing information among midwives that leads to promote self-care for hiesho with respect for the individuality of pregnant women.ConclusionIt was deemed important, in the context of midwifery care for pregnant women's continued self-care for relieving hiesho, to increase the intrinsic motivation of pregnant women for self-care, and related efforts were implemented at a high frequency. The four components of midwifery care extracted in this study encouraged pregnant women to continue self-care for relieving hiesho by motivating them to change their behavior, increasing their self-efficacy for self-care, creating opportunities for them to actively access information about self-care for hiesho, and implementing care that respects their individuality.
