減重對停經前後過重婦女之身體組成、自我效能和飲食行為之影響

Effects of Weight Reduction on Body Composition, Self-efficacy and Eating Behavior in Perimenopause Overweight Women

停經會增加肥胖和腹部脂肪，造成健康的危害。本研究目的要探討短期營養體重控制課程對停經前後婦女減重成效，以及自我效能、身體組成和飲食行為之差異。研究對象共37名，10位停經前和27位停經期過重婦女參與此研究，被指導每日1400±200大卡低熱量飲食、八週營養體重控制課程。並於課程前後測量身體組成、自我效能及飲食行為。研究結果發現兩組減重後身體質量指數、體脂肪重、腰圍、腰臀比有意義減少(p<0.01)，自我效能和飲食行為平均分數有意義增加(p<0.01)，但兩組的減重成效無統計意義。我們的研究結果顯示短期營養體重控制課程對於身體質量指數、體脂肪重、腰圍與腰臀比、自我效能和飲食行為有益的效應，但與經期狀況無關。

Menopause increased the risk of obesity and abdominal fat distribution, which associated increase in health risks. The purpose of this study is to examine the impact of short-term weight control program on body composition, self-efficacy and eating behavior in pre-and postmenopausal women. 37 overweight women participated in this study, 10 premenopausal and 27 postmenopausal women received 1400±200 kcal/day and 8 weeks weight reduction program. Body composition, self-efficacy and eating behavior were measured before and after weight reduction. Data show BMI, fat mass, waist circumference and waist to hip ratio decreased (p<0.01), and self-efficacy, eating behavior increased (p<0.01) in both groups. But there were no significant differences in weight reduction outcome of pre-and postmenopausal women. We conclude that short term weight control program has a beneficial impact on body mass index, fat mass, waist circumference, waist to hip ratio, self-efficacy and eating behavior, irrespective of their menopausal status.
