To improve health among the population and reduce the societal burden of care and health-related costs in a rapidly aging environment, the Japanese government launched the "National Health Promotion Program in the 21st Century" (HJ21), which contains goals concerning areas such as lifestyle behavior and the use of preventive medicine. While health care personnel are responsible for guiding others' health choices, they may not maintain healthy lifestyles themselves. Whether these individuals are meeting the HJ21 goals has not yet been examined. This study aims to determine whether certified specialists in health management are meeting such goals, and to compare their performance with the national average. This is a cross-sectional survey study. Study participants, sourced from all prefectures in Japan, were specialists certified in health management. We measured data concerning demographic information, lifestyle (physical activity, nutrition, diet, sleep, rest, smoking, and alcohol use), and the use of preventive medicine. The study participants exhibited many characteristics of high health literacy. They had an overall healthy lifestyle and met most of the HJ21 goals of healthy lifestyle, and a high proportion underwent health maintenance examinations and cancer screenings. These practices and behaviors maybe associated with high health literacy and social engagement activities.
