[Survey results on the status of implementation of population approach projects for fathers across Japan by their municipalities].

Objectives　This study aimed to examine the status of implementation and details of population-based approach projects that primarily target fathers nationwide. It also seeked to discuss the possibility of providing childcare support to fathers in the community.Methods　This study analyzed the overall results of two surveys undertaken. The primary survey was conducted between December, 2020 and February, 2021 by administering a mail questionnaire within 1,741 municipalities across Japan. A secondary interview survey was then conducted from August to September, 2021, among the municipalities that responded that they are "implementing projects mainly for fathers," and those that obtained consent to participate in this survey.Results　The 837 municipalities (response rate = 48.1%) that responded to the primary survey were included in the analysis. Many municipalities provided paternal and family support in addition to childcare support for mothers, at the time of issuing maternal and child health handbooks and in parent classes. This support was inclusive of distributing leaflets and pamphlets for fathers (P=0.036), encouraging fathers to participate in parent classes (P<0.001), setting dates and times that are easy for fathers to participate in (P<0.001), and including content for fathers (P<0.001). There were significantly more responses from local governments of the municipalities with a total population of 70,000 or more. The number of municipalities that "implemented childcare support that primarily targeted fathers instead of mothers" was 54 or 6.5% of the total. However, about 70% of the municipalities that had not implemented such programs recognized the need for their implementation. In the 21 municipalities where the interviews were conducted, there were 10 projects implemented during pregnancy, 12 during the childcare period after delivery, and 1 implemented across both. The contents of the implemented programs varied widely, with each municipality devising its own programs based on regional characteristics, which had generally favorable evaluations from the participants. In contrast, many municipalities mentioned that the small number of participants was an issue.Conclusion　Although fathers are encouraged to participate in childcare and housework within households, it is rare for them to be given opportunities to gain the required knowledge and skills. Most projects provide support for fathers as supporters of mothers. Going forward, in addition to surveys targeting fathers, there is a need to present project models that can be implemented by the local governments.
