This study examined the relationship between job performance and lifestyle habits among Japanese employees. The results revealed that insufficient sleep was the dominant factor affecting work performance in both men and women, followed by lack of regular exercise and eating late-night meals. In addition, the study showed that men were more likely to exhibit lifestyle habits that affected work performance than women.
In Japan, declining productivity has become a major social issue as the working-age population declines due to a lower birth rate and an increasing aging population. Therefore, companies are focusing on “health and productivity management” initiatives to keep employees healthy and improve their work performance. However, the lifestyle habits that influence the poor work performance of Japanese employees and how they differ between men and women have not been identified to date.
A multiple regression analysis was conducted using data from 12,526 corporate employees (aged 21–69 years) to examine the relationship between 11 lifestyle habits (related to smoking, exercise, diet, alcohol consumption, and sleep) and job performance, by gender. The findings showed that insufficient sleep was most strongly associated with poor work performance for both sexes.
In addition, it was noted that lifestyle habits such as slow walking speed, smoking, and skipping breakfast were associated with lower work performance in men, while in women, habits such as fast eating speed were affected.
The study suggests that health education and workplace interventions that focus on improving sleep, exercise habits and meal times are crucial. Furthermore, it highlights the importance of gender-specific support measures.
