In this study, nutrient intake status and energy expenditure were examined to investigate the nutritional status of the elderly in a rural community. The results obtained by questionaries, the 24 hour recall method, and time-diary were as follows: The elderly men surveyed were 73.8 years old, on the average. The elderly women surveyed were 73.5 years old, on the average. The proportion of the elderly with diseases was 51.9%. Most of the subjects (86.1%) had a regular meal pattern of consuming three meals a day. The average daily energy intake of the rural elderly was much lower than the Korean RDA. The dietary assessment data showed that each energy intake of the males and the females was 79.5% and 84.3% of the RDA, respectively. The dietary intake of Ca, Fe, niacin, thiamin, and riboflavin was lower than the Korean RDA, and that of P and Vitamin C was adequate. The Fe intake was significantly different with respect to age and sex (p < 0.05). Although, in both elderly men and elderly women it decreased with age, the elderly men's intake was lower than the elderly women's. The heights of the elderly men and the elderly women was 159.7 cm and 147.5 cm, respectively, and the weights were 60.0 kg and 52.2 kg, respectively, and the BMI was in the moderate range. Heights significantly decreased with age (p < 0.05). According to daily living schedules, leisure time (11.0 hour) was the longest, physiological time (9.6 hours) was next, and work time (3.4 hours) was the shortest. Energy expenditure significantly decreased with age (p < 0.01). Energy intake also decreased with aging. Energy balance (energy expenditure/energy intake) was 93.4% in elderly men and 104.0% in elderly women. Especially, in elderly men in the 65 to 74 age range, the energy balance was the lowest, and the nutrient intake was also much lower than that of elderly women.
With the object of the study id every possible correlation between daily food intake and growth rate of primary school students, aged eleven years old, the author distributed prepared questionnaires through 200 children of 5th grade in both sexes in K private primary school, Seoul. Specific object of this study were included following three points: such as daily food intake records for six days. daily food intake records for six days. school records of sample children at the end of 4th grade. physical growth index calculated by means of weight and height of sample children at the first part of the 5th grade. CR. t. F. test as well as percentage calculations were included for statistical analysis. The result of this study were as follows: 1. For the living circumstances a) Average numbers of brother and sister in sampled family were two to three. b) Approximately 50%of the children were brought up by mother's milk at their infants and about 35% of children were weaned at the age of 7 to 12 months. c) Thirty to forty percent of the respondents revealed irregulity in their meal time due to early school time in the morning. d) Monthly average expenditure for daily food reached 20 to 29% out of total income. e) The most favorit foods reflect as follows: The most favorit main dish is boiled rice mixed with other careals and side dish beaf. Fruits and juice are more popular snack among whole children. 2. Nutrition survey a) The calcium and thiamine were the most limited factors out of daily nutrients consumption. b) The total calory intake were composed of carbohydrate 63%, protein 16% and fat 21% respectively. c) The total food intake were composed of 20 to 24% of animal source of foods and 76 to 80% of plant source of foods (vegetables, grains, fruits) d) The total protein intake were composed of 46% of animal protein and 54% of others. e) The grain stuffs consumed in the largest quantity at the level of 50% out whole food groups. f) Twenty four percent of total food intake came from snack between meal time. 3. The result of statistical analysis were as follows: a) The correlation between the calory intake and plysical growth index revealed statistical significancy at the level of p<0.001. b) The correlation between the protein intake and physical growth index revealed statistical significancy at the level of p<0.001. c) The correlation between the meal time and physical growth index revealed statistical significancy at the level of 0.02
In order to develop an obesity management program for teenagers, we compared obese and non-obese girls attending high schools in terms of their dietary practices related to snack consumption. Dietary records were collected for 7 days. No significant differences were found for the average daily energy intake between obese and non-obese girls. However, the highest energy intake was greater for obese girls while not much difference was found for the lowest amount of energy intake. Obese girls had significantly lower intakes in calcium (P < 0.01), vitamin A (P < 0.001) and folate (P < 0.01). Mean energy intake from snack ($594.1{\pm}312.1kcal$) was significantly higher for obese girls than for non-obese girls ($360.1{\pm}173.1kcal$) (P < 0.001). A significant, positive correlation was observed between energy intake from snack and total daily energy intake (r = 0.34 P < 0.01) only for obese girls. In case of dietary behaviors, obese adolescent girls consumed significantly greater number of items for snacks and fewer foods for regular meals compared to non-obese girls (P < 0.05). This study suggested that obesity management programs for adolescents should focus on providing strategies to reduce snack through enhancing balanced regular meals.
Objectives: The purpose of this study was to examine the relative impact of seasonal differences and age on dietary vitamin D intakes, outdoor activity time and serum vitamin D status among Korean postmenopausal women. Methods: A cross-sectional study was conducted with 164 free-living postmenopausal women (mean age=55.4 years) in Daegu, Korea. Dietary intake, daily physical activity patterns and fasting blood samples were collected during summer and winter. We compared the results from 75 women during summer and 89 women during winter. Dietary intake of vitamin D was assessed by 24-hour recall method. Daily outdoor activity time was derived from physical activity diary. Results: The average dietary intake of vitamin D of the participants was $3.7{\mu}g$ during summer, $3.3{\mu}g$ during winter, showing no significant difference between the two seasons. The average time spent on outdoor activities was not significantly different between summer ($=35.1{\pm}75.0min/d$) and winter ($=48.5{\pm}76.8min/d$). The average serum 25-(OH) vitamin D concentrations of participants was $17.5{\pm}7.5ng/mL$ in the summer and $13.4{\pm}4.3ng/mL$ in the winter, showing no significant differences by season. Dietary intake of vitamin D was not related to age. When total subjects were divided into two groups by age, the average serum 25-(OH) vitamin D concentration was significantly higher in older group (p=0.047) and time spent on outdoor activities was also (p=0.018) significantly higher in the older group. Conclusions: In order to improve the current vitamin D status of Korean postmenopausal women, nutrition education programs should focus more on adequate intake of vitamin D, while maintaining enough outdoor activities over the season.
This study was peformed to assess the nutritional status of female nursing home residents by dietary intake. The subjects were 60 nursing home residents aged over 60 from 3 different nursing homes in Seoul, Cheonan and Chunchon. Dietary intake was assessed by 24-hr recall and nutrient intake was calculated using CAN-Pro and database for vitamin E established by authors. To establish vitamin E database, we analyzed vitamin E concentration using HPLC in several foods consumed frequently by nursing home residents. The results of nutrient intake were as follows; 1) Average daily intakes of energy, protein, phosphorous, iron, vitamin $B_1$ and niacin were higher than RDA, but calcium, vitamin $B_2$ and niacin of Chunchon were lower than RDA. 2) Intakes of protein, sodium and niacin of Cheonan residents were significantly higher than those of Seoul. 3) Intakes of phosphorous, potassium, vitamin $B_1$ and dietary fiber of Cheonan residents were significantly higher than Seoul and Chunchon. 4) Intakes of sodium and cholesterol of Seoul residents were higher than Cheonan and Chunchon. 5) Average daily intake of vitamin E was lower than RDA. Especially vitamin A intake of Cheonan residents was significantly lower than other two cities.
This survey was carried out to obtain the information concerning nutritional status, including factors of food intake and health condition of elderly women living in Ulsan city. Main results were as follows. 1) Dietary intake data showed the average daily intake of energy, protein, vitamin A, riboflavin and ascorbic acid were lower than Korean recommended dietary allowances (RDA). According to the percentage of RDA, Vitamin A was the nutrient found to be least sufficient. 2) Among the various influencial factors, pocket money, meal-mate, skip meal and health concern influenced on nutrient intake considerably. A meal condition score based on influencial factors, showed significant correlations with all nutrient intake(P<0.001). A health score based n the subjects complains about health condition, showed significant correlations with intake of energy, carbohydrate, thiamin, and niacin(P<0.05). 3) Average hight was below Korea reference, while average body weight of subjects was close to Korean reference. Average body mass index was 23.0. 4) The average systolic and diastolic blood pressure was 140mmHg/88mmHg, the proportion of hypertension was 32.4 percent. The average hemglobin concentration was 12.7g/dl, only 6.7 percent of subjects were anemic. Serum cholesterol concentration was normal range(140~220mg/dl) in all subjects.
The dietary vitamin $B_6$ intake of 185 Korean children aged 7-12 years (y), who showed no health problems, in the Seoul area and its sources were estimated using a modified Korean vitamin $B_6$ database. The age and sex of each subject was classified according to the classifications in the Korean Recommended Dietary Allowance (RDA). Dietary vitamin $B_6$ intake and food sources were estimated using the three-day recall method with the help of a trained interviewer. Food portion sizes were estimated by using standard household measures and published average portion sizes. The average daily vitamin $B_6$ intake was 1.69$\pm$0.50 mg/d in children aged 7-9 y, 1.86$\pm$0.44 mg/d in male children aged 10-12 y and 1.77$\pm$0.62 mg/d in female children aged 10-12 y. Less than 5% of the subjects consumed less than the Korean RDA of vitamin $B_6$. The average ratio of vitamin $B_6$intake to daily protein intake was 0.028$\pm$0.006 mg/g in children aged 7-9 y, 0.028$\pm$0.004 mg/g in male children aged 10-12 y and 0.029$\pm$0.007 mg/g in female children aged 10-12 y. The intake of vitamin $B_6$ was significantly (p<.01) positively correlated to the intake of all other nutrients. Foods from animal and plant sources provided 37% and 73% respectively, of total vitamin $B_6$. Major dietary sources of vitamin $B_6$ in children in the Seoul area were rice, soybean sprouts, pork, beef, cereal, kimchi, milk, onions, and potatoes. As for major dietary sources of vitamin $B_6$, the top 20 foods provided nearly 73-75% of the total vitamin $B_6$ consumed by Korean children.
The anti-stress effects of kimchi were studied in the Sprague-Dawley rats dosed with kimchi. The rats in the stress groups were subjected to immobilization stress for 2 hr/day for 5 days. At the end of the experimental period, daily average food intake and body weight (BW) gain had been reduced in the stress group compared to the control group. Daily average food intake was significantly increased in the stress-kimchi diet group compared to the stress-only group. The weights of the thymus and spleen were decreased by immobilization stress, but this reduction was partially suppressed by the addition of kimchi. The weights of the adrenal gland and epididymal adipose tissue were increased in the stress group, but ingestion of kimchi completely and partially suppressed these stress-induced changes, respectively. Serum levels of total cholesterol and triglyceride, and plasma levels of corticosterone were increased in the stress group, but at control levels in the stress-kimchi diet group.
This study was conducted to investigate the dietary habits and assess the dietary intake of preschool children. Food habit, preference and nutritional supplement status were investigated using a questionnaire answered by the mothers of 453 subjects aged 3 to 6 years old. Also, a dietary intake survey using a 24-hour recall method was performed by mothers of the children. It was found that 81.2% of subjects had milk, dairy products, cookies, fruit and bread between meals once or twice per day. As well, 60.3% of subjects had an unbalanced diet and 20.7% had an overeating habit. Thus, unbalanced diet was a serious problem for many of the subjects. Due to weight controls, digestion problems and allergies, 11.7% of subjects had special dietary consideration. And 26.4% of subjects were using nutritional supplements. From the 24-recall survey, it was found that all nutrient intakes were higher than the Korean RDA except calcium and vitamin A. Nutrient intakes for protein, calcium, phosphorus and vitamin B2 were significantly different by sex, and also increased with age but not significantly. Children received 35% of daily energy, 44% of daily fat and 52% of daily calcium from snacks, so snacks clearly play an important role in dietary intake. The average number of foods consumed per day by subjects was 17.6 and that dishes was 11.0. Most children consumed 4 or 5 food groups per day. In conclusion, the dietary intake of children aged 3 to 6 were deemed adequate judging from nutrient intake and dietary diversity. More attention should be paid to the nutritional value of snacks in this age group.
This study was conducted to evaluate the nutritional status of elementary school lunch programs. The subjects of this study consisted of 170 elementary school students(male 51.8% : female 48.2%) in the 5th and 6th grades. The dietary intake of nutrients was assessed by the modified 24-hour recall method. The results are summarized as follows: the average body weight was 41.3$\pm$7.93kg for boys and 40.5$\pm$ 8.35kg for girls. The average height was 149.5$\pm$5.88cm for boys and 146.2$\pm$5.82cm for girls. The total daily energy and nutrient intake was below the RDA's except for the intake of niacin and ascorbic acid. School lunchs provided 31.5% of total energy intake ; 32.5% of carbohydrate intake, 31.9% of protein intake and 33.4% of fat intake. Therefore, school lunchs largely contributed to the nutritional balance of these children. The food habit score was poor for 40.6% of the subjects.
