Influence of a community-based approach to improve risk factors of lifestyle diseases by Japanese public health nurses: A case-control study

BACKGROUND AND OBJECTIVES: It is important to examine the roles of specific health check-up and specific health guidance in individuals at high risk of common lifestyle diseases, but evaluation based on a stratified analysis of people undergoing a health check-up has not been adequately performed. In this study, we examined the effects of providing specific health guidance to individuals considered at high risk for a lifestyle disease after specific health check-ups. METHOD: Subjects who underwent a specific health check-up in 2012 were assigned to either a group that received health guidance from public health nurses over three years (n = 393) or a control group (n = 109). Clinical findings of both groups were analysed to evaluate the correlation between their changes and health guidance. RESULTS: A significant decrease was observed in blood pressure, and lipid and glucose levels only in the health guidance group. Multiple regression analysis revealed that health guidance was the explanatory variable of serum lipid improvement. DISCUSSION: Continued support by Japanese public health nurses through health guidance closely related to the subject's lifestyle over three years may lead to a comprehensive reduction in the risk of lifestyle diseases.
