目的：探討元智大學學生身體組成變化與內臟脂肪增加的情形。方法：所有受試者男學生為1,209人，女學生為1,145人，再依年齡分為6組（18-23歲）。身體組成以節段式整合頻率生物電阻法進行分析。統計方式以單因子變異數分析比較年齡層之各測量項目的差異，並以獨立樣本t考驗比較男女生之各測量項目的差異，本研究之顯著水準為α=.05。結果：研究結果顯示在22及23歲組男女生之脂肪量無明顯差異外，其餘各年齡層的各測量項目男女生皆達顯著差異(p<.05)，包括男生在肌肉量、腰臀圍比、內臟脂肪量及腰圍的數值明顯高於女生，而在體脂肪量及體脂肪百分比，女生數值明顯高於男生。此外男女生之部分測量項目在各年齡層間達顯著的差異(p<.05)，特別是男生的差異類別多與脂肪有關，且大部分為18與22、23歲年齡層之間的差異。結論：本研究主要發現大學時期男生雖然在體脂肪量仍低於女生，但體脂肪已有隨年齡增加的趨勢，且脂肪分布明顯集中於內臟部位。

Purpose: To understand the body composition variation and visceral fat increase for the students of Yuan Ze university. Methods: Students (1,209 male and 1,145 female subjects) were divided into six groups by age (18-23 years old). Body composition was analyzed by segmental multi-frequency bioelectrical impedance analysis. A one-way analysis of variance among the different groups and Scheff's protected least significant differences test was performed. The differences between male and female of students were analyzed by independent t-test. It holds the value of a type I error to 0.05 for each test. Results: The fat mass of male and female students was not different at 22 and 23 ages. Male students were significantly higher than female students in skeletal muscle mass (SMM), waist to hip ratio (WHR), visceral fat area (VFA), and waist circumference (WC). However, Female students were significantly higher than male students in body fat mass (BFM) and percentage of body fat (PBF). Besides, some measurements of male or female at all age groups were significant differences (p<.05), especially, the differences of the measurements was related to the fat, and most of the differences between the groups of 18, 22 and 23 ages for male student. Conclusions: Our main finding is that male students were lower than female students in body fat mass during the college period, but male students banked up much fat at abdominal area and increased more visceral fat with age.
