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, and 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 for employees at baseline was 40.3 years and the proportion of women was 25.8%. The confusion matrix for evaluating model performance had 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 for health services (0.084) and medical services (0.050); the percentage of full-time employees working in sales departments (0.074), distribution or customer service departments (0.054); the percentage of employees who sleep well (0.055); and the percentage of employees who have a habit of regular exercise within a company (0.043).
Conclusions The lifestyle health risk factors of employees 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
