[A study on medical examination items added to periodic health examination as a result of amendment of the Ordinance on Occupational Safety and Health].

In accordance with the recent amendment of the Ordinance on Occupational Safety and Health, anemia (Hb, RBC), liver function (GOT, GPT, gamma-GTP), serum lipid levels (T-Chol, TG) and ECG have become essential items of the general periodic health examination. Data on these items were examined on 86 employees on whom chest radiography, blood pressure, urinalysis and past history revealed no abnormalities in periodic health examination at their companies. The subjects were 58 males and 28 females, between 34 and 66 years old (47.6 years on average). Anemia was found in 3 (3.5%), liver dysfunction in 13 (15.1%), abnormal serum lipid levels in 24 (27.9%) and ECG abnormalities in 8 (9.3%). The new periodic health examination system is thus thought to be useful in the early detection and prevention of adult diseases. To enhance this utility, it appears important to instruct those found abnormal in any parameter to have extensive examination. In discussing liver function and serum lipid level abnormalities, obesity, drinking and food intake should be considered.
