Abstract
We assessed the association of employee lifestyles (e.g., smoking, exercise, drinking, and sleep habits) with mental health-related absenteeism and turnover rates utilizing data from the annual Health and Productivity Management survey by Japan's Ministry of Economy, Trade and Industry. This analysis included data from 1,748 companies, encompassing 4,199,021 employees. The average proportions of mental health-related absenteeism and employee turnover rates were 1.1% (±1.0%) and 5.0% (±5.0%), respectively. In multivariable regression models that incorporated all lifestyle factors and confounders, a 1 percentage point increase in the proportion of employees who slept well was associated with reductions in their turnover rate (mean -0.020%; 95% CI, -0.038% to -0.002%) and in mental health-related absenteeism (mean -0.005%; 95% CI, -0.009% -0.001%). A similar increase in the proportion of employees engaging in regular physical activity corresponded with a 0.005% decrease in the prevalence of mental health-related absenteeism (95% CI, -0.010% to -0.001%). A 1 percentage point increase in the proportion of employees who smoked was associated with a 0.013% reduction in mental health-related absenteeism (95% CI, -0.017% to -0.008%). Nonetheless, the current study's observational and cross-sectional design restricted the ability to establish causality between employee lifestyle factors and mental health issues.

Abstract
OBJECTIVES
Using a dataset from a survey on national health and productivity management, we identified health and productivity factors associated with organizational profitability.
METHODS The Ministry of Economy, Trade and Industry conducted an annual survey on Health and Productivity Management between 2014 and 2021. We assessed the associations of organizational health and productivity management using survey questions collected in 2017 and 2018, with the rate of change in profits from 2017 and 2018 to 2020. We identified factors associated with organizational profitability using eXtreme Gradient Boosting, and calculated SHapley Additive exPlanation (SHAP) values for each factor.
RESULTS Among 1,593 companies (n= 4,359,834 employees), the mean age of employees at baseline was 40.3 years and the
proportion of women was 25.8%. A confusion matrix for evaluating model performance had an accuracy of 0.997, precision of 0.993, recall of 0.997, and area under the precision-recall curve of 0.999. The most important factors related to an increase in corporate profits were the percentage of current smokers (SHAP value, 0.121), per-employee cost of health services (0.084) and medical services (0.050); the percentage of full-time employees working in sales departments (0.074) and distribution or customer service departments (0.054); the percentage of employees who slept well (0.055); and the percentage of employees within a company who regularly exercised (0.043).
CONCLUSIONS Employees’ lifestyle-related health risk factors and organizations’ management systems were associated with organizational profitability. Lifestyle medicine professionals may demonstrate a significant return on investment by creating a healthier and more productive workforce.
