Development of method of nutritional survey for health education

为了利用真人大小食物模型评价食量频数法的有效性，对社区生活对象(男、女，40~69岁)进行了该方法和24小时回忆法的营养调查。按摄食量和频率法计算的总能量为2258千卡，蛋白质为85.1g，脂肪为53.6g，碳水化合物为56.6g。从能量摄入的百分比来看，蛋白质占15.1%，脂肪占21.4%，碳水化合物占56.6%。食物量和频数法显示总能量、蛋白质、脂肪和碳水化合物的摄入量平均是24小时回忆法的1.25倍，食物组中大多数项目的摄入量都较大。这两种方法显示的脂肪百分比能量摄入的结果是相同的。总能量、三种主要营养素的摄入量与个体脂肪的能量摄入量百分比有显著的相关性。显著相关的是…在食物组的大多数项目中都有更多的营养。我们还发现这两种方法的结果在总能量、三种主要宏观营养素和能量摄入量的百分比之间存在显著的相关性。这一方法可用于检测能量和三种主要营养素的摄入量，因为它得到的结果略大，但与全国营养调查结果几乎相同。由于该方法不需要特殊的技能，而且可以由采访者根据方法的指导进行，因此可以应用于了解社区的食物摄入状况。我们开展了降低胆固醇水平的健康教育项目，并利用食物量和频度方法在滋贺县进行了干预研究。受试者为上一年年度体检中胆固醇水平在240 mg/dl以上的志愿者。结果显示，与对照组相比，干预组的胆固醇水平降低了7 mg/dl。较少

For the pur pose of evaluating the validity of food amount and frequency method using life-size food models, nutritional survey by this method and 24-hour recall method were carried out on 64 community-living subjects (male and female, 40-69 of age). Amounts of intake resulted from food amount and frequency method were 2258kcal of total energy, 85.1g of protein, 53.6g of fat and 56.6g of carbohydrates. As for percent energy intake from this method, the results were 15.1% of protein, 21.4% of fat, and 56.6% of carbohydrates. Food amount and frequency method showed larger amount of total energy, protein, fat and carbohydrate intake than 24-hour recall method by 1.25 times on average, and larger amount of intake in most of the items in food groups. These two methods showed the same results of fat percent energy intake. Significant correlations were obtained as to intakes of total energy, three major nutrients, and individual percent energy intake of fat. Significant correlations were obta … More ined in most items of the food groups. We also found significant correlation between the results of these two methods in total energy, three major macro-nutrients and percent energy intake when categorized into threegroups in the or der of the amount of intake. This method can be available for detecting the intake of energy and three major nutrients, because it obtained slightly larger but nearly the same results with the national nutrition survey. Since this method requires no special skills and can be carried out by interviewers given directions on the method, it can be applied to understand the status of food intake of a community.We carried out a health education program for decreasing cholesterol level and made an intervention study in Shiga Prefecture utilizing the food amount and frequency method. Subjects were volunteers with the cholesterol level of above 240mg/dl in the annual checkup of the previous year. Results showed 7mg/dl lower cholesterol level in the intervention group compared with the control group. Less
