Implementation rate of periodic health checkup at manufacturing factories in Kawasaki]

A questionnaire survey on periodic health checkup was conducted on 4,432 manufacturing factories in Kawasaki and the following results were obtained. 1) Implementation rate of periodic health checkup was 100% in factories with 100 workers or more. In smaller factories employing less than 100 workers, the implementation rate decreased with decrease in their total work force. The rate was 47.5% and 37.7% in factories with 9-4 and 3-1 workers, respectively. 2) The proportion of workers less than 30 years of age decreased and that of 60 or more years of age increased with decreasing size of the total work force. Distribution of both age groups was 12.6% and 12.9%, respectively in factories with less than 10 workers. The proportion of female workers increased from about 10% in factories with 300 workers or more to 26.8% in factories with less than 10 workers. 3) In large factories with 500 workers or more periodic health checkups were implemented mostly at their own or related medical facilities and in factories with 499-10 workers, almost 50% were implemented in independent health service facilities. In factories with less than 10 workers periodic health checkup were implemented mainly at health centers (33.1%) and at hospitals or clinics (26.9%). 4) The main reasons why small factories could not implement periodic health checkup were: (1) they could not afford the time for the implementation (50.0%) and (2) ignorance of the law of mandatory periodic health checkup for workers (23.6%).
