Examination of a nationwide cohort of individuals with high health literacy in terms of their health-related lifestyles and attainment of the goals of the “National Health Promotion in the 21st Century” Program

Abstract

Abstract Background: In Japan, where the population is aging particularly rapidly, “healthy aging” is being advocated as a means of addressing the potential societal burdens caused by older adults’ need for nursing care and the high associated health-care costs. To improve healthy aging among the population, the Japanese government has launched the “National Health Promotion in the 21st Century” (HJ21), which contains goals concerning areas such as lifestyle behavior and use of preventive medicine. Low health literacy is associated with many health-related issues; however, whether individuals with high health literacy are meeting the HJ21 goals has not yet been examined. This study aims to determine whether a cohort with high health literacy are meeting such goals, and to compare the cohort’s performance with the national average. Methods: This is a cross-sectional survey study. Study participants, sourced from all prefectures in Japan, were professional specialists in health management certified by the Japanese Association of Preventive Medicine for Adult Disease. We measured data concerning the cohort’s demographic information, health perception, lifestyle (including physical activity) and use of preventive medicine. Results: The cohort showed many characteristics of high health literacy. The cohort had an overall healthy lifestyle and met most of the HJ21 goals; in particular, a high proportion underwent health-maintenance exams and cancer screenings. Conclusions: The high health literacy cohort showed a healthy lifestyle. Compared to the national average, a higher proportion of the cohort met the HJ21 goals and received preventive medicine.
