Society health issues and health management strategies
Beginning in FY2023, the Society conducts a Health Management Survey of all employees. This survey is intended to help visualize trends in lifestyle habits and identify key factors and obstacles in our efforts to raise health awareness.
The Health Management Survey this time covered employee awareness of behavioral tendencies related to seven lifestyle habits: nutrition, exercise, smoking, mental health, sleep, alcohol consumption, and stiff shoulders/lumbar pain.
Looking at the survey results for fiscal year 2024, there were no major changes from the previous fiscal year, but in terms of diet, the number of people who try to eat a balanced diet increased compared to the previous fiscal year, indicating that employees’ health awareness has improved.
The state of employee health issues identified through the survey will be reported in the monthly meeting of the Health and Safety Committee and other occasions and used in efforts toward solutions to health issues (such as seminars, walking rallies, and other activities), in order to improve employee health.
