長い生活史を持つ高齢者は、生来的な体質とともに過去の生活形態によっても、体格が規定される傾向がある。戸外での重労働に従事した高齢者の特徴の一つに円背があり、そのことが身長を低くしている。閉経後血中エストロゲンは急速に減少し、副甲状腺ホルモンに対する骨の感受性を高めるために、高齢女性には骨粗鬆症が多い。摂取した栄養素あるいは太陽光の浴び方によって骨面積に相違が見られるが、骨粗鬆は骨に関係した疾患を引き起こしやすい。高齢期に骨密度の低下しやすい女性に焦点をあて、３地点を特定し、65歳以上の高齢者を対象に、身長、体重から体格を表すBMIを算出し、骨密度との関係を生活形態の違いが明らかな３地域を比較し、地域における格差の有無を検証した。特に農業従事者の多いＹ県の特定地域の高齢者を軸に、都市部でスポーツに親しむＫ県Ｙ市在住者、20～30歳代でアメリカに移住しアメリカ文化の中で多くの時間を過ごしたLos Angeles 在住の日本人女性との比較で報告する。

Among older people, their physique is influenced by how they have lived their lives as well as inherent characteristics. One of the characters that has seen among people who served outside labor, such as agriculture is a round-shoulder that causes their lower heights than those who were not outside labor, such as agriculture is a round-shoulder that causes their lower heights than those who were not outside workers. A round-shoulder also causes narrower range of vision, less caution to obstacles ahead, and stumbling and falling at steps. Older women are more suffering from osteoporosis after menopause, which causes lower secretion of estrogen and more sensitivity of bone to the parathyroid hormones. Although there are some differences in the covered area of bone due to intake of nutrition and a level of exposure to the sun, many bone related diseases occur because of osteoporosis. Our research compared older women (age 65 and above), who resided three different areas, to verify a difference in each region and its influences. The study investigated their diet, life style, some physical characteristics, such as heights and weights, and their bone density by using a computerized device, called VenusⅡ. Interview to each subject was conducted as well as survey and measurement methods. First, the research was administrated in the rural area, Y prefecture, where most subjects had served as farmers through their life. Then we investigated women who lived in the urban area, K prefecture, where the subjects enjoyed some kinds of physical activities, and then we researched women who had lived in Los Angeles, California as immigrants and spent most of their life in cross-cultural environment.
