The Effectiveness of Health Promotion Programs for Enhancing Healthy Lifestyles Among Working Adults in Enterprises

Abstract

This study aimed to evaluate the effectiveness of a workplace health promotion program on healthy lifestyles across four dimensions (physical, mental, social, and spiritual well-being). A one-group pretest–posttest design was conducted among 428 employees from 34 workplaces over a 6-week intervention. Following the program, participants demonstrated significant reductions in weight, body mass index (BMI), and waist circumference (p < 0.01). Significant improvements were also observed in dietary behaviors (reduced frequency of sweet, fatty, and salty food consumption) and alcohol-use patterns (p < 0.001). Furthermore, mental health, overall quality of life, family relationships, and satisfaction with the work environment improved significantly (p < 0.001). These findings suggest that an integrated workplace health promotion program has the potential to enhance health behaviors and well-being among the working-age population. However, given the study's lack of a control group and limited follow-up duration, these results should be interpreted as preliminary evidence.
