摘要

研究目的：探討台北地區不同年齡層體質指數配對之受試者其脂肪分佈之型態和休息時心率和血壓的關係。方法：54位年齡在20到82歲體質指數相似之志願健康受試者參與本研究，將男性和女性受試者依年齡分為三組，20-39歲為第一組、40-59歲為第二組及60歲以上為第三組。測量每位受試者休息時心率、血壓、肱三頭肌、肩胛下和腹部皮層厚度，以及腰、臀處之周長。使用無母數統計分析之克－瓦氏單因子等級變異數分析(Kruskal-Wallis H test)探討男性和女性受試者各脂肪分佈測量項目組間是否存有差異，並以曼－惠特尼檢定(Mann-Whitney U test)任兩組間的差異。另以皮爾森相關係數檢定脂肪分佈測量項目與休息時心率和血壓的關係。結果：第二組和第三組男性的體脂肪比例均較第一組高，第三組的腰圍和腰臀比明顯較其他兩組為高。第三組女性較其他兩組女性的體脂肪比例、腰臀比明顯為高，腰圍、血壓僅較第一組高。不論男女，三組在三個皮層厚度上均無明顯差異，腰圍和腰臀比都與收縮壓有明顯相關。結論：即使在體質指數配對之受試者中，年齡確實會影響一些代表脂肪分佈的指標，且與收縮壓有明顯相關。

Purposes: To investigate changes in fat distribution with aging in subjects with matched body mass index (BMI), and examine the correlation with heart rate and blood pressure. Methods: Fifty-four healthy volunteers aged from 20 to 82 years were included in this study. They were matched with body height and weight, and divided into three groups by age for each gender, with the age of 20-39 years as Group Ⅰ, 40-59 years as Group Ⅱ, and ≥60 years as Group Ⅲ. Resting heart rate, systolic and diastolic blood pressure, triceps, subscapularis, and abdominal skin-fold thickness, and circumferences of the waist and hip were measured. The Kruskal-Wallis H test and Mann-Whitney U test were used for group comparisons of these measures. Pearson product moment correlation coefficient was used for correlation analysis. Results: Male subjects of Group Ⅱ and Ⅲ showed significantly higher percent of body fat than Group Ⅰ; Group Ⅲ showed significantly larger waist circumference and waist-hip ratio than the other groups (p＜0.017). Female subjects of Group Ⅲ showed significantly higher percent of body fat and waist-hip ratio than the other groups. Waist circumference and blood pressure in Group Ⅲ women were only higher than Group Ⅰ. None of the triceps, subscapularis, or abdominal skin-fold thicknesses significantly differed among the three groups. Waist circumference and waist-hip ratio were both positively related to systolic blood pressure in both genders. Conclusions: Waist-hip ratio, an indicator of central fat patterning, was significantly greater in both elderly groups. Along with waist circumference, both indices were related to systolic blood pressure.
