Objective To evaluate the effectiveness of intervention for health risk factor in hospital employees. Methods This study was carried out among 339 employees of a hospital in Jinan, Shandong Province. Based on the results of Health Risk Appraisal for 14 health risk factors, we designed a 6-months intervention program for the most widely distributed and intervenable health risk factors; and then evaluated the changes of health risk factors after 6 months. Results After 6-month intervention the prevalence of 3 health risk factors decreased (P ＜ 0.05 ): physical inactivity decreased from 57.8% to 38.6%,hyperlipidemia from 9.4% to 5.3%, and unhealthy dietary from 28.9% to 14.8%. Compared with the baseline data, the average number of health risk factors were reduced from 3.10 to 2. 71 ( P ＜ 0. 01 ).Conclusion The intervention can reduce health risk factors effectively.
