Abstract

This study was performed to investigate the effect of 12-week weight control program including nutrition education, diet therapy and regular exercise on body weight, obesity degree, BMI and blood lipid levels among middle aged obese women. The 31 middle aged obese women participated in the weight control program for 12-week. The body weight, body composition, blood lipid levels and food habit were measured before and after the weight control program. Changes in body weight after 12 week weight control program showed the slight reduction from $67.4{\pm}10.8kg\;to\;65.1{\pm}9.2kg$. Obesity degree and BMI were decreased from $128.4{\pm}19.1%,\;27.8{\pm}3.9\;to\;123.4{\pm}15.7%,\;26.8{\pm}3.0$, respectively. Waist-hip ratio was also decreased from $0.98{\pm}10.16\;to\;0.94{\pm}0.04$. LBM was also slightly reduced from $39.9{\pm}5.6kg\;to\;37.0{\pm}8.5kg$ with the reduction of body fat. The levels of systolic blood pressure, total cholesterol and triglyceride were slightly decreased, HDL-chol level was significantly increased from $43.1{\pm}14.1mg/dL\;to\;50.4{\pm}16.5mg/dL$. Waist-hip ratio was also slightly decreased after 12 weeks. Food habit score was significantly increased after nutriton education and personal counseling about their eating behaviors and nutritional status.

본 연구는 $35{\sim}55$세 중년 여성을 대상으로 운동과 식사요법을 중심으로 12주간 체중 조절 프로그램을 실시한 후 대상자들의 비만도 및 혈액 지질 개선 효과, 식습관 변화에 미치는 영향을 조사하였고 그 결과는 다음과 같다. 1. 12주간의 체중 조절 프로그램 실시로 체중, 체지방량, 체지방률, BMI, 비만도 모두 유의성은 없었지만 감소되었다. 체중은 $67.4{\pm}10.8kg$에서 $65.1{\pm}9.2kg$으로, 체지방량은 $27.6{\pm}6.9kg$에서 $26.7{\pm}7.5kg$으로 프로그램 실시전과 비교하여 0.9 kg 정도 감소되었다. 체지방률(%)도 $40.6{\pm}5.2%$에서 $39.6{\pm}5.1%$로 감소되었으며 제지방량(FFM)도 $39.9{\pm}5.6kg$에서 $37.0{\pm}8.5kg$으로 감소를 보였다. 2. 대상자들의 비만도 (Obesity degree, %)와 체질량지수 (BMI)는 프로그램 실시 전 각각 $128.4{\pm}19.1%,\;27.8{\pm}3.9$에서 프로그램 실시 후 $123.4{\pm}15.7%,\;26.8{\pm}3.0$로 감소하였다. 복부 비만도(WHR)도 프로그램 실시 전과 후 각각 $0.98{\pm}0.16$에서 $0.94{\pm}0.04$로 변화되었다. 3. 체중조절 프로그램 실시 전후 혈압, 공복시 포도당, 중성지방, 콜레스테롤 농도 모두 뚜렷한 변화는 없었지만 수축기 혈압이 $119.19{\pm}17.03mmHg$에서 $114.55{\pm}17.86mmHg$으로 감소되었고, 총 콜레스테롤은 $179.35{\pm}34.46mg/dL$에서 $173.45{\pm}38.88mg/dL$로, 중성지방은 $174.71{\pm}91.33mg/dL$에서 $167.44{\pm}47.31mg/dL$로 유의성은 없었지만 모두 감소한 반면, 동맥경화 억제요인인 HDL-콜레스테롤 농도는 $43.06{\pm}14.05mg/dL$에서 $50.38{\pm}16.47mg/dL$로 증가되었다. 4. 대상자들의 식습관 분석 결과 영양교육 실시 전 18.7점에서 실시 후 20.8점으로 증가하였으며 특히 가장 점수가 낮았던 ${\ulcorner}$만복감${\lrcorner}$${\ulcorner}$식품의 배합${\lrcorner}$ 항목에서 개선되었고, 그외 ${\ulcorner}$음식의 간을 싱겁게${\lrcorner}$${\ulcorner}$채소섭취${\lrcorner}$ 항목도 영양교육 실시로 인해 크게 개선되었다. 5. 식사 일기 기록을 통한 영양소 섭취 분석 결과 1일 총 열량 섭취량은 $30{\sim}49$세 경우 프로그램 실시 전 $1,774.7{\pm}486.1kcal$에서 실시후 $1,189.1{\pm}310.5kcal$로 낮아졌으며, 50세 이상에서도 프로그램 실시 전과 후 각각 $1,549.4{\pm}327.1kcal,\;1,371.4{\pm}221.0kcal$로 감소하였다. 1일 단백질 섭취량을 비롯하여 지방, 칼슘, 철분, 비타민 C의 섭취량도 열량 섭취량 감소에 따라서 섭취 권장량 이하로 감소되었다.
