本研究主要探討大學員工身體組成的情形，同時觀察隨年齡增加造成的身體組成改變。研究對象男女性員工各為72與162人（年齡38.5 ± 0.90 vs. 33.3 ± 0.48歲、身高171.7± 0.79 vs. 159.5 ± 0.41公分及體重74.2 ± 1.41 vs. 55.4 ± 0.6公斤），將其分為男女各5群組（26-30；31-35；36-40；41-45及46-50歲），並以生物電阻法分析身體組成。研究結果顯示男性各組的腰圍、腰臀圍比、肌肉量、脂肪量及內臟脂肪量皆高於女性（p<.05），而女性各組之體脂肪百分比則高於男性（p<.05）。男性第46-50歲組之腰臀圍比大於第26-30歲組（p<.05），且年齡與腰臀圍比顯著正相關（r=.30, p<.05）。女性在腰臀圍比及內臟脂肪量各組間達顯著差異（p<.05），同時腰臀圍比、腰圍及內臟脂肪量與年齡達顯著正相關（r=.60, .18, & .44, p<.05）。本研究主要發現女性在26-50歲期間，體脂肪量及體脂肪百分比未明顯變化，但內臟脂肪量卻隨年齡而增加，顯示體內脂肪分佈在這段期間有集中於腹部內臟的趨勢。

The purpose of this study was to research the body composition for college staff, and the variation of body composition by aging. 72 man (age: 38.5 0.90 yrs; height 171.7 0.79 cm; weight 74.2 1.41 kg) and 162 woman staff (age: 33.3 0.48 yrs; height 159.5 0.41 cm; weight 55.4 0.6 kg) were divided to 5 groups by age (26-30; 31-35; 36-40; 41-45; 46-50 age group). Body composition was analyzed by segmental multi-frequency bioelectrical impedance analysis. The result of this study was that the waist circumference (WC), waist to hip (WHR), body fat mass (BFM), and visceral fat area (VFA) of all man group were significant higher than all woman group (p<.05), but the body fat mass (BFM) of all woman's group was significant higher all man's group (p<.05). At men, it was significant higher for WHR in 40-50 than 26-30 age group, and positive correlation between age with WHR (r=.30, p<.05). At women, it was significant difference for WHR and VFA in all age group, and positive correlation between age with WC, WHR and VFA (r=.60, .18, & .44, p<.05). Our main finding was that the WHR and BFP of woman staff were not significantly variation during 26-50 age, but woman staff banked up much fat at abdominal area and increased more visceral fat with age.
