[The effects of individual milk-drinking habits on nutrient intake and dietary patterns in men and women in Tottori Prefecture].

This study was performed to determine the actual conditions of milk-drinking habits in men and women, and to ascertain their effects on nutrient intake and dietary patterns. The 809 subjects were over 20 years of age and were obtained from the Tottori Prefecture Dietary Survey. The results are summarized as follows: 1. Over 40 percent of the subjects did not consume any milk during the three days of the dietary survey. Furthermore, only 38 percent of men and 46 percent of women have daily milk-drinking habits according to the results of the questionnaire. 2. Calcium and Vitamin B2 intake level and total serum cholesterol level were higher in milk-drinkers than non-milk-drinkers, in both men and women. The regression of total calcium intake from 6 groups of food was analyzed by multiple regression analysis. For both men and women who were milk-drinkers, total calcium intake was determined mostly by milk. In the case of non-milk-drinkers, total calcium intake came mostly from green vegetables for men, and other vegetables for women. 3. The ratios of both animal proteins and animal fats were higher in milk-drinkers. For women, energy percentage of fats was high and that of carbohydrates was low in milk-drinkers. The results seem to suggest that differences in dietary patterns is based on milk-drinking habits. Using the Hayashi's quantification method 3, dietary patterns were classified into two groups based on milk-drinking habits. Dietary patterns of milk-drinkers included the characteristic of eating bread, meats, and fats more frequently in men, fresh vegetables, eggs, fats and bread in women. In men, milk-drinking habits had a lesser influence on diet than in women.
