To examine the effect of annual health checkups on medical expenditures in Japanese middle-aged workers.
Medical expenditure data were accumulated from a health insurance society with 38 affiliated companies in Japan. Eligible employees (1811 men and 787 women) aged 40 to 55 years, who received medical care in 2002 (baseline year) and 2006 (4 years later) were surveyed about their participation in health checkups in 2003, 2004, and 2005.
After adjusting for medical care use in the baseline year, the 4-year total (2003-2006) of medical expenditures was significantly lower in those who had more frequent health checkups for both genders. The 4-year change (from 2002 to 2006) of medical expenditures was inversely associated with the frequency of health checkups, and this association was statistically significant for men.
Annual health checkups may contribute to reduction of medical expenditures in Japanese middle-aged workers.
研究年度健康检查对日本中年员工医疗费用的影响。
从日本一家拥有38家附属公司的健康保险协会收集医疗费用数据。对2002年（基准年）和2006年（4年后）接受医疗护理的40至55岁合格员工（1811名男性和787名女性）进行调查，了解他们在2003年、2004年和2005年参加健康检查的情况。
在对基准年的医疗护理使用情况进行调整后，两性中健康检查更频繁的人群在4年（2003 - 2006年）内的医疗总支出显著更低。医疗费用的4年变化（从2002年到2006年）与健康检查频率呈负相关，且这种关联在男性中具有统计学意义。
年度健康检查可能有助于降低日本中年员工的医疗费用。
