[Questionnaire survey of municipalities on policies to promote physical activity among residents: An examination by administrative sector and population size].

Objectives　National policies to promote physical activity and exercise have been formulated by several ministries and agencies in Japan. This study aimed to examine the formulation and implementation of such policies in municipalities by administrative sector and population size.Methods　After stratifying all municipalities in Japan at the population level, we randomly selected 272 municipalities. We collected 1,632 cases in six sectors (health, sports, education, urban planning, transportation, and environment) within these municipalities.　A questionnaire survey on the status of policy formulation, implementation, and coordination among departments was conducted as a cross-sectional study. Differences between groups of municipalities were statistically analyzed using Fisher's exact test. The survey period was from September 2018 to March 2019.Results　A total of 616 responses were collected (response rate 37.7%). The response rates for health and education were lower than those for the other sectors. The rate of policy formulation to promote physical activity was extremely high in the health and sports sectors, and there was slight variation by population size. In contrast, formulation rates were generally low in the urban planning, transportation, and environment sectors, especially in smaller municipalities. In the sectors mentioned above, physical activity promotion projects mainly involved the development of exercise and sports infrastructures. Health, sports, and education were the primary sectors that used those environments. Regarding interdepartmental coordination in policy implementation, a cooperative relationship existed among the health, sports, and education sectors and between the urban planning and transportation sectors. However, smaller municipalities were found to have fewer opportunities for such collaboration and tended to implement policies independently.Conclusion　This study clarifies the policy formulation and implementation for promoting physical activity in municipalities at the national level in Japan. In addition, their characteristics were identified based on different administrative sectors and population size. These results are expected to be used in future local government policies.
