[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.
