北京市8个社区高脂血症膳食干预效果分析

为探讨以社区为基础的高脂血症膳食干预效果 ,在高脂血症筛查的基础上 ,从北京市新街口等 8个社区随机抽取 180名高脂血症患者和血脂偏高者 ,按所在社区分为试验组和对照组。试验组进行膳食干预 ,随访 6个月 ,于干预前后分别进行膳食调查 (72小时回顾法 )、体格检查和血脂指标检测。经过干预 ,试验组能量摄入减少 13 2 % ,脂肪摄入减少 2 4 75 % ,胆固醇减少 2 4 4% ,烹调用油减少 2 2 43% ,降低幅度明显大于对照组 (P <0 0 5 ) ;三大营养素供能比例趋向合理 ;试验组体重降低 0 17% ,体质指数降低 0 6 7% ,腰臀比降低 3 37% ,其中体重和体质指数的变化相比对照组差异具有显著性 (P <0 0 5 )。试验组血清总胆固醇、低密度脂蛋白胆固醇分别降低 0 2 9mmol L(5 6 1% ,P <0 0 5 )和 0 2 5mmol L(7 0 6 % ,P <0 0 5 ) ,而对照组无明显变化。结果提示 ,以社区为基础的膳食干预可以有效地改善高脂血症患者的膳食结构 ,控制体重 ,降低血清总胆固醇和低密度脂蛋白胆固醇水平

Effects of dietary intervention on hyperlipidemia in eight communities in Beijing

Based on the data available from hyperlipidemia screening, 180 participants were recruited and divided into intervention group and control group. Dietary intervention lasted six months and dietary survey, anthropometry and serum lipid determination were performed and analyzed respectively before and after the intervention. The results showed the decreases of total calories, fat, cholesterol and oil by 13.20%, 24.75%, 24.40% and 22.43% respectively in participants of intervention group. The percentages of total calories provided by fat, carbohydrate and protein trended to be desirable and the reductions were also observed in body weight and BMI. There were 5.61% and 7.06% reductions in total serum cholesterol and low-density lipoprotein cholesterol in intervention group, while no significant reduction in the control group. These results indicated that the community-based dietary intervention could effectively improve dietary pattern, control body weight, decrease the level of total serum cholesterol and low-density lipoprotein cholesterol.
