摘要

本研究之目的為了解青少女骨質密度、影響因素及其預測因子，採橫斷性研究設計，以南台灣500位16-18歲之青少女為研究對象，進行問卷調查及骨質密度測量，並以SPSS軟體進行描述性及推論性統計分析。研究顯示：研究對象平均骨質密度為-0.21；不論骨質密度正常或不良者，半數以上皆未有規律運動之習慣，且多從事低負荷及無負荷之運動；身體質量指數、自覺健康狀況（與同年紀相較）與骨質密度呈顯著差異；身體質量指數為青少女骨質密度之預測因子。本研究結果可提供衛生署及縣市衛生局，作為青少女骨質疏鬆防治政策擬訂之參考。

The purpose of this study is to understand the bone mineral density of adolescent girls, related factors and predictors. A cross-sectional study was conducted among 16-18 years old adolescent girls in southern Taiwan. Quantitative ultrasound measurement and structural questionnaire were applied in each subject. A total of 500 valid samples were collected. The data were analyzed by SPSS. The results showed that: (1) the subjects' average bone mineral density was -0.21; no matter the subjects with normal bone mineral density or not, more than half of them didn't have the habit of regular exercise. They almost didn't do high weight-bearing exercise; (2) BMI, self-perceived health status and bone mineral density have significant difference; and (3) BMI was the predictor of bone mineral density of adolescent girls. The results could be provided to health departments and county/city health bureaus for reference on policy of osteoporosis prevention for adolescent girls.
