摘要

本研究探討營養教育配合不同程度商業減重代餐的應用在減重計畫上，對減重成效及生活品質之評估。實驗A組使用所提供之減重代餐一包取代一天的部份飲食，實驗B組每日使用兩包代餐取代部份飲食。兩組控制熱量的攝取是依照個別體重與活動量計算出總熱量後再減五百大卡，並完成自填式問卷包括生活品質問卷、及背景資料問卷等，實驗進行為期12週。實驗A組共16名，平均減輕體重和減輕BMI分別為8.23±3.70公斤和3.09±1.38，減輕體重和BMI分別為9.44±3.67%和9.75±3.87%。B組共14名，平均減輕體重和減輕BMI分別為9.43±2.74公斤和3.68±1.03，減輕體重和BMI分別為11.65±3.03%和11.60±3.04%。實驗A組減重後追蹤三個月之體重仍持續下降，體重從78.18±9.57降至73.96±6.92。實驗B組亦有顯著下降，體重從71.79±11.02公斤降至68.27±9.38公斤。A、B兩組追蹤六個月體重及BMI則與減重後三個月所測得的數值大致相同, 並無顯著下降。減重前後兩組腰臀圍、腰臀比、血糖、尿酸、血膽固醇、三酸甘油脂及低密度脂蛋白有顯著下降（p＜0.05）。但兩組間改變的差異並無達顯著的不同。SF-36兩組健康相關生活品質量表在減重12 週後，其SF-36健康相關生活品質量表中，生理功能（PF）、因生理功能問題而角色受限（RP）、身體疼痛（BP）、一般健康（GH）、活力（VT）、社會功能（SF）、因情緒問題而角色受限（RE）、心理健康（MH）八個構面及「體能綜合評估」（PCS）、「心理綜合評估」（MCS）兩個面向呈現統計學意義上的進步，尤其在一般健康（GH）最顯著。惟兩組之間在所測向度中也並未達顯著的不同。結論：代餐減重配合營養師的諮詢，可異於傳統的取代全餐的代餐介入方式，將代餐取代部分餐食，不僅有良好的減重成效並可全面提昇健康相關之生活品質，代餐介入的程度不同對減重成果及生活品質並無顯著的影響。

The purpose of this study was to evaluate the effectiveness of weight loss and life quality by the method of nutrition education along with providing different degree of liquid meal replacements. Group A and group B received meal replacements once and twice daily, respectively, for 12 weeks of study. The total calories controls in both groups are based on the calculated energy needs minus 500 Kcal/day. Body weight, waist and hip, biochemical examination and several structured questionnaires were used for data collection at before and after study. Group A (n＝16； male＝3，female＝13) and group B (n＝14；male＝6，female＝8) were aged 38.3±15.2 and 32.6±9.5 years, with body weights of 86.41±10.87 and 81.22±11.79 kg, and BMI of 31.54±3.65 and 31.81±3.24 kg/m2, respectively, before treatment. There were significant weight loss in both groups, 9.44±3.67% and 11.65±3.03%, however, no significant difference was found in between groups. Waist and hip measurements, blood sugar, cholesterol, triglyceride, and LDL concentrations had significantly decreased in both groups (p＜0.05), however, no significant difference was found in between groups. Physical functioning(PF), role-physical(RP), bodily pain(BP), general health(GH), vitality(VT), social functioning(SF), role-emotional (RE), and physical component summary (PCS) in the Medical Outcomes Study Short-Form 36 Health Survey (SF-36, as the assessment of HRQL) were also showed significant improvement, but again there was no significance in between groups. We concluded that the use of nutrition education along with liquid meal replacements provide significant weight loss and improvement in quality of living. However, the degrees of intervention did not contribute significant difference in the treatment outcomes.
