  • A deep understanding of the dietary patterns and nutrient intake is important for assessment of possilbe nutritional risk and for establishing nutrition improvement strategies. This study was conducted toexamine the dietary characteristics of a nutritionally poor elderly group compared to the middle-and highly-nourished group. Elderly participant was recruited from local elderly centers in Suwon city in 1998. Trained dietitians interviewed 119 elderly(35 males, 84 females) aged 60 years and over for collecting dietary data(24-hour recall) and related variables. Male and female subjects were grouped into high, middle, and low according to the mean nutrient adequancy ratio(MAR) tertiles. An analysisof the percentage of RDA(Recommended Daily Allowances of Korea) for each of the 10 nutrients showed that the male low-MAR group consumed below the RDA in all kinds of nutrients, and the female low-MAR group consumed nutrients below the RDA except vitamin C. An evaluation of nutrient density by Index of Nutritonal Quality(INQ) also showed a similar tendency. Thus, the INQ level of the male low-MAR group was significantly lower than the middle-or high-MAR group, especially in protein, vitamin A, thiamin, riboflavin, and phosphorus(p<0.05). Moreover, INQ level of female low-MAR group was significantly lower than that of the high group(p<0.05) in all nutrients. The female low-MAR group's daily food intake were also lower than those of the high-MARgroup in gains, fish, fruits, oil and beverages. The energy distribution from carbohydrates, fats and proteins showed that the male low-MAR group had significantly higher carbohydrate and lower fat proportions compared to each gender high-MAR group, respectively. The male and female low-MAR group had low scores about eating all side dishes. These findings indicate that a moderate increase of the meat/egg/fishes intake was needed by the male low-MAR group for improving nutrition adequacy, and an overall increase of the food quantity and quality was desired for the female low-MAR group. These data could be used for planning a community elderly nutrition program and establishing strategies for tailored guidelines for the individuals.

  • To establish a basic cohort which can survey the nutrient and food intake related to the health status of the middle and old-aged vertically, a longitudinal survey of 110 adults over forty years old was conducted three times in Chon-ju city over 5 years (1994-1999), and the influences of health status by changes in their nutrient and food intake were examined in this study. The results were as follows ; The number of subjects was 110(43 man, 67 women), 10.0% in their forties, 28.2% in their fifties, 45.4% in their sixties 6.4% over seventy, and their average age was 61.4. There were decrease of height about 1cm , increase of body fat % and few changes of BMI during the testing period. As the subjects were aging, the percentage of anemia increased, but averages of blood pressure and blood glucose(men : 91.8mg/㎗, women : 90.3mg/㎗) were constant. Total cholesterol increased from 196.7mg/㎗ to 212.6mg/㎗(P 0.05) over five years, and the numerical values for women were higher than that of men. In many cases, lack of nutrient intake was shown, as compared with the Recommended Dietary allowance(RDA) especially calcium and vitamin A(71.7%, 64.9% of RDA). Grains intake showed a tendency to decrease(P 0.01). On the contrary, fruit intake showed a tendency to increase(P 0.001). On whole meal, plant foods were 85.1% and animal foods were 14.9%. As dietary factors influencing health status were investigated, blood glucose was influenced by vitamin B$_2$, potatoes and triglyceride, DBP and SBP were affected by vitamin B$_1$, vitamin C, legumes, fishes, triglyceride and age. Total cholesterol was under the influence of triglyceride, milk, seeds and fat. BMI was influenced by iron, SBP, animal food, and age.

  • The purpose of this study was to evaluate the nutritional status of elderly women living in residential homes by estimating nutrients and food intakes. Food consumption survey was conducted by 3-day 24hr recall method with 99 elderly women aged 65 to 90 years from three residential homes in Seoul, Choonchun and Chunan and 46 free-living elderly women aged 65 to 88 years from Chunan as control group. Food intake data was converted into nutrient intake using computer aided nutritional analysis program. Mean energy intake and percentage of recommended daily allowance (RDA) of residential home residents were 1696㎉ and 101% of RDA while those of control were estimated as 1939㎉ and 119% of RDA. On average, absolute amount of nutrient intakes of residential home residents were slightly higher than control group. Subjects in control group showed significantly lower carbohydrate and vitamin A intake, while vitamin C intake was higher. However, nutrient intake quality determined by INQ (Index of nutritional quality) was significantly higher among control subjects in most nutrients except vitamin A than residential home residents. Intakes of calcium, vitamin A and riboflavin of all subjects in this study were less than 75% RDA meaning that nutritional status of calcium, vitamin A and riboflavin was insufficient and could possibly result in nutritional deficient. Some food groups such as milk or other dairy products must be strongly suggested to improve nutritional status of elderly women in this study. According to the results of this study, meal plans of residential homes are quite adequate in quantity of micronutrients, but need to be improved in both quantity and quality of micronutrients.
