Urban-rural difference in the acceptance of mass health examination in north-eastern Japan

Over 40,000 residents (less than or equal to 40 years of age) in a city (Sendai; the city group), a town (Shiroishi; the town group) and two villages (Wakuya and Tajiri; the village group) in Miyagi prefecture in north-eastern Japan responded in a questionnaire survey on their attitude towards mass health examinations (i.e., whether they underwent in the previous year and if so where) on 4 items of blood pressure measurement, chest x-ray examination and screening tests for stomach and cervical cancer. The coverage rates were about 70% on an average both for blood pressure measurement and for chest x-ray examination, whereas the rates for cancer screening were between 30-40%. As for the opportunity of the former two examinations, the workplace mass examination played a large role in the case of the city and town groups (especially among men but not women) in addition to visit to clinics, in contrast to the case of the village group in which people depended much on regional mass examination service. The trend was essentially reproducible in stomach cancer screening although the over-all coverage rate was low, whereas women in the three groups almost exclusively utilized clinics for cervical cancer screening with one exception that the mobile unit service appeared to be equally accepted in the village group.
