[Comparison between Kanagawa Prefecture and Ohio state of factors related to health behavior among older adults]

Factors related to health behavior of older adults in Japan and the United States were compared. A total of 900 persons from three age groups (45 to 59, 60 to 74 and 75 and over) were interviewed in three communities (major metropolitan, midsized city, and small town), in both Kanagawa Prefecture and Ohio State. To determine the reliability of the results, in addition to analysis for all subjects, each of communities were analyzed separately. Health behaviors were divided into 2 separate levels: 1) preventive health behaviors and 2) coping behaviors for symptoms which may be signs of a serious illness. The latter behaviors were classified into three types: 1) seeing a physician, 2) changing lifestyle and 3) taking OTC drugs. The following results were obtained: 1) In both Kanagawa Prefecture and Ohio State, good preventive health behaviors were unrelated to coping behaviors associated with potentially serious illness. Interviewees who used OTC drugs when experiencing a potentially serious illness had a low tendency toward seeing a physician. In Kanagawa Prefecture, individuals who saw a physician showed a strong tendency toward changing their lifestyle, for symptoms which were potential signs of a serious illness. 2) There were some differences in factors related to preventive health behaviors between Kanagawa Prefecture and Ohio State. In Kanagawa Prefecture, there were sex differences, with males exhibiting preventive health behaviors. In Ohio State, good preventive health behaviors were few among interviewees who were black. 3) There was little difference between Kanagawa and Ohio State as far as the tendency toward seeing a physician when experiencing potentially serious illness. In both places, interviewees with good self-rated health status and having strong self-treatment attitudes showed a lower tendency to see a physician when experiencing symptoms which were potential signs of a serious illness.
