RESUMO
This study attempts to develop and verify the effectiveness of a health promotion program for office workers based on the social ecological model and the World Health Organization's Healthy Workplace Framework. This study involved 272 office workers of a small and medium-sized enterprise in Korea. Data were analyzed through descriptive statistics, repeated measures analysis of variance (ANOVA) and Bonferroni correction using SPSS/WIN 23.0. Workplace environmental support was provided to all workers, while a 6-month intensive core program based on social support was implemented for the intensive management group. Based on the participation rate, individuals were divided into the core and dropout groups. In all office workers, there were negative changes in high-density lipoprotein cholesterol and job stress during the period. Meanwhile, the intensive group showed significant changes in body mass index and diastolic blood pressure. The study suggests that the organization's support for a healthy environment and an individual's continued participation based on social support are essential for the effectiveness of a health promotion program for office workers.
