标题：An Epidemiological Study on the Structural Analysis of Nutrition Intake in Urban and Rural Inhabitants of Sasayama in Hyogo through Two Nutrition Survey Methods
摘要：A 3-day nutrition intake survey was carried out on 42 and 46 women in urban and rural areas respectively. A questionnaire nutrition intake survey was carried out on 70 and 87 women of the same age in the same areas. The characteristics of the nutrition intake in these two areas were analyzed using two methods: the comparative study of the amount of intake and the structural analysis of nutrition intake through component analysis. The results obtained were as follows: 1) The amount of intake shown was somewhat larger in the questionnaire survey than in the 3-day nutrition intake survey. 2) The questionnaire survey disclosed that as far as noodles, meat, or fruit were concerned, the inhabitants in the rural area tended to answer a smaller amount of intake than that of the 3-day nutrition intake survey. 3) As a result of the structural analysis of food intake, it was seen that in the urban area people tended to eat a fair amount of Western foods, while in a rural area they preferred Japanese foods, with rice being the type of food most earten. 4) The structural analysis of the nutrition intake showed that the persons' score of the factor loading of 1st and 2nd components was scattered on almost the same area in graph for both the urban and rural areas. Apparently, nutrition intake was much the same in both areas, though the style of food was different. 5) A questionnaire nutrition survey was found to be quite effecive in grasping the nutrition intake of the inhabitants at the time of medical screening examination. It is likely to be a more useful method if question items are to be improved in the future.
