Evaluation of effect of nutrition education for prevention of lifestyle related disease

1.自编包含65份食物清单的半定量食物频率调查问卷(FFQW65)，用于生活方式相关疾病预防的营养教育。本调查问卷对71名男性志愿者的营养素摄入量进行了重复性和相对有效性的调查。每隔10个月两次使用FFQW65，并以一周加权食物摄入量调查结果作为参考方法来评估其相对效度。用对数转换后的数据计算皮尔逊相关系数。作为效度，早餐总能量摄入量的皮尔逊相关系数为0.87，预测值与加权食物摄入量实测值的相对差值较小(差值为-13千卡，相对差异率为1.1%)。午餐、晚餐和一天的预测被低估了(分别为0.52、0.66和0.64)。16种营养素的一天摄入量(除…外)更多的m和烟酸)在0.28到0.64之间。)。能量调整后的蛋白质、铁和胆固醇的相关系数变得更差(分别为0.16、0.14和0.19)。其余13种营养成分的平均值在0.26~0.65之间。FFQW65似乎足以对受试者进行排名，特别是根据能量、脂肪、碳水化合物、钙和维生素的摄入量。生活方式相关疾病预防营养教育评价研究设计：编制基于方便半定量食物频率问卷(FFQW65)的营养评价程序。研究对象为40~65岁男性，属于糖尿病高危人群。随机分为非干预组(常规营养教育)和干预组(采用FFQW65营养评价程序)。干预组营养教育的主要策略是关注能量摄入并保持适当的条件。以1年后血糖下降10%为评价指标。结果与结论：建立了应用FFQW65进行能量摄入评价的程序，并开始了干预研究。目前针对40岁以上男性400人的干预研究正在进行中。较少

1. A self-administered semi-quantitative Food Frequency Questionnaire with 65 food lists (FFQW65) was developed for the nutritional education of lifestyle related disease prevention.Methods. Reproducibility and relative validity of nutrient intake as assessed by this questionnaire was investigated in volunteers of 71 males. The FFQW65 was administered twice at an interval of 10 month, and to assess the relative validity, one week weighted food intake survey result served as reference method. Log translated data was used to obtain Pearson correlation coefficients.Results. As the validity, Pearson correlation coefficient of total energy intake of breakfast was 0.87 and the relative difference between predicted value and weighted food intake survey was relatively small (the difference was -13 Kcal and relative difference rate was 1.1 %). Those of lunch, supper and one-day were underestimated (0.52, 0.66 and 0.64, respectively). The one-day intakes of sixteen nutrients (except for potassiu … More m and niacin) ranged from 0.28 to 0.64. ). Energy adjusted correlation coefficients for protein, iron and cholesterol became much poorer (0.16, 0.14 and 0.19, respectively). Those for the other thirteen nutrients were ranged from 0.26 to 0.65.Conclusion. The FFQW65 seems adequate for ranking subjects especially according to intake of energy, fat, carbohydrate, calcium and vitamin C.2. Study design for the evaluation of the nutrition education for lifestyle related disease prevention.Study design : Nutritional evaluation procedure based on convenient semi-quantitative food frequency questionnaire (FFQW65) was developed. Study subjects were the male aged 40-65 who belong to the high risk group of the DM. Non-intervention group (with usual nutrition education) and intervention group (with the nutritional evaluation procedure using FFQW65) were randomly assigned. The main strategy of the nutrition education in the intervention group is focusing on the energy intake and keeping it with proper condition. 10 % reduction of glucose level (2fFG) after one year was used as an evaluation index.Results and conclusions : The intake energy evaluation procedure using FFQW65 was developed, and the intervention study was started. The intervention study for men 400 persons 40-year-old is the progressing at present. Less
