Change in Lifestyle through Health Promotion Program without Face‐to‐Face Intervention in a Large‐scale Japanese Enterprise: Yasuo HARUYAMA, et al . Department of Public Health, Dokkyo Medical University School of Medicine—Objective The aim of this study was to assess the effect of a health promotion program with 2−3‐month Internet or printed material support without a face‐to‐face intervention at a largescale worksite. Methods An uncontrolled intervention was conducted. In 2005, 22,429 employees underwent a health check‐up and a lifestyle assessment. In 2006, 2,096 employees were recruited to participate in an intervention group (IntG), and the remaining 20,228 employees were allocated to a control group (ConG). After one‐year follow‐up, 1,888 employees in IntG and 15,474 employees in ConG were analyzed by Breslow's lifestyle index, overall prevalence of cardiovascular risk (OPCR) and 10% 10‐year risk based on cardiovascular risk factors in 2007. Results Breslow's lifestyle index (over 5 points) in IntG showed a higher OR (1.13 with a 95% CI of 1.01−1.26) than that in ConG. Compared with those with a poor lifestyle, the subjects who had maintained or improved their lifestyle showed a lower OPCR (OR 0.88, 95% CI 0.79−0.97; OR 0.84, 95% CI 0.74−0.95 [ p for trend=0.003]) and 10% 10‐year risk trend (OR 0.38, 95% CI 0.31−0.47; OR: 0.29, 0.22−0.37 [ p for trend <0.001]). Conclusion The present study showed that there was a modest lifestyle behavior change using a program without face‐to‐face contact. The employees who maintained and improved their lifestyle had a lower OPCR and 10% 10‐year risk. Future study should increase the number of employees actively attempting to improve their lifestyles at a worksite.
