Nutritional Status of the Oldest-elderly Population in Sunchang County / 대한지역사회영양학회지

This study was investigated nutrient intakes and dietary evaluation index of the healthy subjects over 85 of Sunchang County to explore the improved dietary pattern for healthy aging of the elderly. The survey was conducted by personal interview to 161 elderly subjects (59 males and 102 females over 85) in 2006, and their daily dietary intake was assessed by 24-hr recalls and weighing one meal. The daily energy intakes of males were 1,335 +/-67 kcal, and those of females were 1,095 +/-38 kcal comprised of 66.8% and 68.4% of the EER for the age group of 75. The proportions of energy from carbohydrate : protein : lipid were 70.7 : 14.6 : 14.6 for males and 68.6 : 14.0 : 17.4 for females. The average protein intakes were 95.4% for males and 85.0% for females of RI, and the average calcium intakes were 54.3% for males and 43.6% for females of RI. The daily vitamin intakes were below 70% except vitamin A, vitamin B6, and vitamin E. The proportion of the relative risk groups of protein, phosphate, iron and vitamin A ranged 40-49% of RI over 75 year groups. The other nutrient intakes showed that there were over 50% risk groups. Especially for nutrients such as calcium, vitamin B1, vitamin B2, vitamin C, folate and niacin over 70% of the subjects were under risk. The median value of all nutrient intakes did not reach AI. The INQ of nutrients were over 0.8 except for folate and vitamin C. Calcium intakes were relatively low and needed attention. However, the ratio of calcium and phosphate showed 1 : 1.6, which appeared to be superior to the other districts. The DVS were higher as the dietary balance scores, KDDS were higher, and the groups with high KDDS had high intakes of nutrients compared to the groups with low KDDS. The high risk groups as judged by simple nutrition screening test had lower nutrient intakes than the groups of middle risk or low risk groups. The subjects in Sunchang area had relatively low intakes of several nutrients. However, judging from the desirable patterns of the energy proportion from three major nutrients, ratio of calcium and phosphate and INQ of nutrients there is a possibility that extended healthy aging might be related to the quality of nutrients and relative ratio between nutrients. To improve nutrient status of the elderly of the surveyed area further application involving KDDS and DVS appeared to be required.

The Influence of Food Habits on Nutrient Intake and Body Mass Index in Elementary School Students in the Gyeongnam Area / 대한지역사회영양학회지

The influence of food habits on nutrient intake and anthropometric measurements of elementary school students was studied from November 2005 to July 2006. 160 elementary school students in the Gyeongnam area were individually interviewed to obtain 24-hour dietary recalls of two seasons (winter and summer). During each period, three interviews were done for 3 nonconsecutive days including two weekdays and one weekend day. The food habits were estimated by questionnaire. The food habit score was 21.5 +/- 2.7 out of a maximum of 30. The nutrient intake of children was low in calcium and vitamin A. Except for that, most other nutrients were overconsumed. The nutrient intakes consumed in winter were significantly higher than those of summer. Comparing the anthropometric measurements between the summer and the winter periods, height was significantly higher in the summer than in the winter. However, body fat ratio was significantly higher in the winter than in the summer. There was a significant positive correlation between the scores of food habits and the vitamins and minerals intakes of the summer period. However, the relationship was much weaker between the food habits and those consumed in winter. In addition, the scores of food habits were significantly negatively correlated with most of the anthropometric measurements of both periods. In conclusion, the students' food habits may reflect the intakes of vitamins and minerals of only the previous few months, however they reflect the BMI of children for a period of more than 6 months.

A Study on Nutrient Intake During Pregnancy of Women of Premature Delivery (I) / 대한지역사회영양학회지

Inadequate nutritional status of pregnancy can cause underweight and premature birth, undergrowth and deliverance of physically and mentally defected babyies. The purpose of this study is to provide guidelines for preventing preterm delivery in the aspect of nutritional factors. The nutrient intakes were compared between a preterm delivery group and a normal term delivery group to recognize risk factors of preterm delivery. The results obtained are summarized as follows. The pregnancy period was statistically longer in the normal term group (p < 0.0001). Weight increase was statistically higher in the normal term group (p < 0.0001). Calories (p < 0.05), carbohydrates (p < 0.0005), dietary fibers (p < 0.0001), potassium (p < 0.0005), vitamin B1 (p < 0.0005), vitamin B6 (p < 0.05), vitamin C (p < 0.0001), and folic acid (p < 0.05) intakes were statistically higher in the normal term group. Nutrient density of vitamin B1 (p < 0.05) and vitamin C (p < 0.0001) in the normal term group was statistically higher. Nutrient adequacy ratio of zinc (p < 0.05), vitamin B1 (p < 0.05) and folic acid (p < 0.05) were statistically higher in the normal term group. Index of Nutritional Quality of vitamin B1 (p < 0.05) and vitamin C (p < 0.0001) were statistically higher in the normal term group. In this study, the normal term delivery showed higher intakes of calories, carbohydrates, dietary fiber, crude fiber, potassium, vitamin B1, vitamin B6, vitamin C and folic acid than the preterm delivery group. Deficiencies in various nutrients may lead to preterm delivery, therefore, balanced nutrient intake is recommended to prevent preterm delivery.
