Current Status of the National Health Screening Programs in South Korea.

A health check-up is one of the best ways to prevent diseases and maintain health by screening for risk factors and diagnosing diseases early. As the burden of illness shifts from infectious to chronic diseases, the importance of health check-ups is emphasized. Korean health authorities began the National Health Screening Programs (NHSPs) for public servants and private school staff in 1980. The NHSP is composed of the National Cancer Screening Programs (NCSPs) and general health checkups. NCSPs, started in 1999, included screenings for stomach, liver, colorectal, breast, and uterine cervical cancers, and they may have contributed to the improved cancer survival rate from 42.9% in 1993-1995 to 77.5% in 2013-2017 in Korea. General health check-ups included lifestyle questionnaires, anthropometric measurements; blood pressure measurement; visual acuity test; hearing test; laboratory tests including fasting glucose, lipid profile, liver function tests, creatinine, and urinalysis; and, chest radiography. Additionally, bone density, cognitive function, and depression were assessed. Testing for non-communicable diseases has improved the control rates of chronic diseases such as hypertension and diabetes mellitus. Favorable changes in the risk factors for cardio-cerebrovascular diseases may lead to a decline in age-standardized mortality and heart disease over several decades. However, many areas of the programs need to be improved. NHSPs should be designed on the basis of individual health conditions, medical needs, and scientific evidence. Greater opportunities to receive NHSPs should be provided to socioeconomically vulnerable individuals. In addition, stricter quality control of NHSPs is required. Follow-up management after the NHSPs should be systematized. In conclusion, NHSPs have contributed to the improvement of public health; however, several aspects of these programs must be addressed.
