Factors Affecting Subjective Health Status in Individuals Undergoing the Ningen Dock

抄録

Objective: Self-rated health concerning healthy life expectancy is used in the Comprehensive Survey of Living Conditions. The subjective health status of serious-disease-free persons undergoing the Ningen Dock may not be influenced by disease-related factors. This study, thus, aimed to clarify what improves self-rated health in such cases.

Methods: Participants were 8,857 persons aged 20–89 years (males: 65%, 53.4±10.8 years) who underwent the Ningen Dock at Jikei University Hospital in 2019 and responded to a questionnaire. The relationship between 16 factors and self-rated health, stratified by sex, was examined using age-corrected linear regression analysis.

Results: Nine factors were related to self-rated health: absence of diabetes mellitus treatment, low heart rate, low alcohol consumption, balanced diet, exercise for ≥30 min, sufficient rest by sleep, low stress, presence of someone to approach for worries, and having hobbies.

Conclusions: The results are consistent with eight previously reported factors. Further, low heart rate was a newly identified factor of self-rated health in this study. In particular, participants with a heart rate of 45–49 beats per minute reported good subjective health status.
