The purpose of this study was to investigate the effects of dietary behavior on the nutritional status of university students in Korea. A dietary intake survey of 603 university students (223 males and 380 females) was conducted using a 24-hour recall method. The resulting data on dietary behavior and nutrient intakes were analyzed by the SAS program package. The main results were as follows : 1) Most of the subjects were in their twenties and no obese cases were found. 2) Dietary intake data showed that, except for vitamin C in the female students, the average daily intakes of most nutrients did lot meet the Korean Recommended Dietary Allowances (RDA). The study also showed that most of the subjects, especially the female students, were concerned about having satisfactory physical appearances. Fat provided 25% of the daily energy intake, and this level was higher than the 20% recommended by the Korean Dietary Guidelines. In the female students, the iron intake from animal foods was lower than that from plant foods. 3) Male students were not very serious about healthy eating. However, the female group, who obtained a high score in dietary behavior, consumed more vegetables and had higher intakes of energy, protein, Ca, p, vitamin A, and vitamin C than the male group, even though they did not meet the Korean RDA in most nutrients. Energy intake from fats, as a percent of total energy intake, was lower than in the group of females who obtained higher stores in dietary behavior than the other groups. To sum up, the university students surveyed in this study were found to have the typical dietary behavior of young adults, such as frequent eating out and snacking. Female students were extremely conscious of their body images this can exert an important direct influence on their dietary intakes and health status. It is very important for university students to develop healthy lifestyles and desirable dietary behaviors, to best enable them to continue to lead a healthy lift: in their later years.
The study aims to evaluate the nutritional status and influence of school meal intakes on RDA of primary school children in Akure community, Ondo State, Nigeria. A cross-sectional study was conducted among 728 primary school children aged between 6 and 15 years. Data were collected using interviewer-administered semi-structured questionnaires. The questionnaires collect information on demographic characteristics and home dietary intake of the subjects. The heights and weights of the children were measured using a standard procedure and height-far-age and weight-far-height z-score were determined. The children's school meal intakes were weighed for 4 days and samples were collected for chemical analysis. The results showed that 37.8% of the children were not wasted, 35.7% mildly wasted, 18.7% moderately wasted and 7.8% severely wasted. Also, 57.8% were not stunted, 29.3% mildly stunted, 11.0% moderately stunted and 1.9% were severely stunted. The subjects' home dietary intakes showed that 73.6% ate starchy food only, 19.9% ate protein based food, while 11.6% and 11.5% consumed fruits/vegetables and snacks to complement home meals respectively. The chemical composition of school meal was energy 379 - 413kcal, moisture content 5.9 -7.3g, carbohydrate 56.5 - 69.4g, fat 4.6 - 12.7g, crude fiber 0.1 - 2.4g, ash content 3.6 - 8.5g and protein 14.9 - 22.3g. The mineral contents were calcium 45.9 - 59.2mg, sodium 5004 - 59.6mg, zinc 2.3 - 3.1mg, magnesium 55.0 - 61.6mg, potassium 55.3 - 69.3mg, copper 0.2 - 0.3 mg, while others 1.3 - 1.9mg, 243 - 659mg and 831 - 9,510mg were iron, phosphorous and vitamin-A respectively. The contribution of school meals to subjects' RDA was within 2.9% and 1540%. In summary, school meal intake contributed positively to the RDA and nutritional status of the school children.
The survey was conducted for the period from 25 th to 29 th July, 1990. The survey area were selected the mountain area in Kang Won Province. Intake of foods and nutrients of all members in the households surveyed by means of questionnaire was computed based on number of meals a day. On the other hand, daily intake of nutrients by an individual was calculated by sex, age and type of work based on the conversion rate of RDA (Korean Recommended Dietary Allowances for Adult). 1. Status of food intake. The average food intake per person per day in surveyed area was 1103.49 g. The total intake of food was consisted of 44.17% grains, 23.31% vegetables, 10.66% fruits, respectively. These findings led us to the conclusion that people in the surveyed area depended heavily on plant foods. 2. Status of nutrient intake, 1) The average intake of Calorie was 2567.54 Cal Per day, which was slightly higher than 2500 Cal of RDA. 2) The average Intake of protein was 82.92g per day, which was higher than 70g of RDA. Though the quantity was above the RDA, it was largely from plant foods 3) The average intake of calcium was 383.93 mg per day, which was much lower than 500 mg of RDA. 4) The average intake of iron was 11.88 me per day, which was nearly the same quantity as 10 mg of RDA. 5) Intake of vitamin group were high among the inhabitants than recommended by RDA 3. The Kinds of food intake The kinds of food intake in surveyed area were totally 66 different kinds. 4. Economic status. As for the education level, almost of the food handlers finished the primary school and the average monthly income was 364,600 in surveyed area. Households used gas(100%) for fuel.
The purpose of this study was to confirm that calcium intake and healthy status play a role in reducing the risk of cardiovascular disease, to assure that calcium intake and regular exercise are important in reducing serum lipid levels in middle-aged women. Daily nutrient intakes were analyzed by convenient method. Anthropometric measurement such as body weight and height and blood pressure were measured. The subjects divided into two groups : women in group I under 50 years of age($\leq$49 yr group) and those in group II 50 years up($\geq$50 yr group). Average ages of group I and II were 43.87 and 53.46 years. The nutrients intake of subjects were higher than Korean recommended dietary allowances(KRDA) except calorie, iron, calcium, vitamin B1. They showed significant difference each other in vitamin B2(p<0.05), calcium(p<0.01) intake. Mean daily calcium intake was 540.88mg in $\leq$49 yr group and 519.50mg in $\geq$50 yr group. The levels of serum cholesterol, triglyceride, blood pressure, Atherogenic Index(AI), LDL/HDL and Cardiac Index(CI) were increased with age. The triglyceride and total cholesterol concentrations and LDL/HDL in $\geq$50 yr group were significantly higher than those of $\leq$49 yr group. There was a highly significantly positive correlation between age and triglyceride, total cholesterol and Atherogenic Index(AI). Triglyceride, total cholesterol, LDL-cholesterol concentration and Atherogenic Index(AI) were positively correlated with body weight and WHR(waist-hip ratio). Also ther was a significantly negative correlation between exercise and Cardiac Index(CI). Also a significantly negative correlation was found between Ca intake and LDL-cholesterol. Exercise and Cardiac Index(CI) also had a significantly negative relation. The results suggest that increased habitual physical activity and calcium intake should be recommended as a way of decreasing blood lipids and blood pressure in middle-aged women.
This study was to evaluate the effectiveness of nutritional counseling for farmers by using computer- based program to estimate pre - and post - knowledge and attitude changes. The desirable change of both knowledge and attitude focused on improving food Intake and early easing of body complaints. 311 agricultural workers in Korea were chosen for this experiment. The score was compared by 2 methods. In the first method, the scores were calculated from nutrient intake quantity and indices. In the second method, the difference of pre and post test of nutritional counseling by count of correct answers of foods and food preparation attitudes was measured according to different body complaints status. Major farming type was rice-planting(39%). The consciousness of health status of the subjects of less than 50 years old was good(42%), but it was only 20% in over 50 years' group. Female farmers felt uncomfortable in body complaints. Their body complaints were 2 times more than the male farmers, particularly, in over 50 years group. Nutrient intakes were lower in male based on the KRDA, except for vitamin C, niacin, and phosphate. Female farmers' nutrient intake was adequate based on the KRDA, but was low in vitamin A, pyridoxin, and iron. From the scores of knowledge and attitude by pre and post tests, counseling was efficient In nutritional education of all age groups, especially the older ones. The effect of counseling by farming type showed that the real agricultural workers had more increased score In the post test. This results Indicated that counseling about food, nutrition. and health to these workers was always effective. Therefore nutritional counseling and education program should be developed for different kinds of health and nutrition. It would be conducted to promote food behavior and improve nutritional and health status of farmers.
This study was conducted to examine the nutritional status, quality of diet and quality of life in postmenopausal women with mild climacteric symptoms based on their food group intake patterns. The data for nutritional status were obtained using 3-day records. Quality of diet was assessed by INQ, NAR, MAR, DDS, DVS, DQI-I. Climacteric symptoms were analyzed by the questionnaire of Kupperman's index and MENoL. The subjects were classified into the five groups, GMVDF, GMVdF, GMVDf, GMVdf, GmVDF according to their food group intake patterns. Analysis of nutrient intakes showed that the GMVDF group took significantly higher levels of kcal, carbohydrate, protein, fat, vitamin A, thiamin, riboflavin, folate, vitamin C, vitamin E, calcium, phosphorous, sodium, iron, zinc and fiber than GMVdf group did (p < 0.05). INQ of Ca and Fe appeared to be higher in GMVDF than in GMVdf groups (p < 0.05). Analysis of NARs showed that missing milk groups took lower riboflavin, Ca and P than other groups did as the same result with MAR (p < 0.05). Analysis of DDS and DQI showed that GMVdf group had the lowest quality of diet (p < 0.05); however, no difference was found on DVS. The GMVdf group showed the worst climacteric symptoms compared with those of the other groups (p < 0.05). However, we couldn't observe any differences in menopause-specific quality of life among the groups. In conclusion, it would be beneficial to meet all five food groups to increase the quality of diet and to reduce the climacteric symptoms in postmenopausal women.
This study was conducted to examine dietary factors affecting bone status in the rural aged men. Quantitative ultrasound measurements (QUS) of bone, that may reflect certain architectural aspects of bone, have been shown to be associated with bone mineral density and fracture. Information of diet and anthropometry was collected in 164 aged men. Dietary intake data were obtained by 24-hour recall method. Measurements of the speed of sound (SOS, m/s), at distal radius, mid-tibia, phalanx, were performed using Omnisense 7000S analyzer (Sunlight Ltd., Tel Aviv, Israel). T-scores for bone SOS measurements at distal radius, mid-tibia and phalanx were 0.60, 0.03 and -0.42 respectively. The prevalence of osteopenia by use of the WHO criteria was 17.7% at the mid-tibia and 25.3% of the subjects at the distal radius. Age were negative association with bone SOS at three sites. Osteopenia group of radius were significantly lower in total foods and vegetable intakes than normal group. After adjusted for age, vegetable intakes were significantly and positively related to bone SOS at the radius. The bone SOS of the tibia were significantly and positively related to vegetable protein, iron, folate and vegetable intakes, but negatively related to fat intakes. Multiple regression analysis showed that bone SOS of tibia was positively associated with folate intakes. Vegetable intakes were positively associated with the bone SOS at three sites. These results indicate that the consumption of vegetables, sources of folate, may have a effect on bone status of men.
This study was conducted to investigate the relationship among prevalence of obesity, nutritional status and factors related to obesity of women who exercise regularly. The subjects of this study were 100 women who have been exercising regularly for more than 6 months. They were mostly housewives ages 24 to 63 years and had graduated middle or high school. Their average income was form 700 to 1,500 thousand won per month and most of them had 2 r 3 children. They sleep usually 6~8 hours a day. Most of physical indices of obesity were increased progressively with age. Among them , weight (61.5$\pm$1.4kg), subscapular (16.3$\pm$1.4mm) and abdomen(31.4$\pm$1.2mm) skinfold thickness were higher in 50 years than in others. BMI after exericse was decreased compared with BMI before exericise. WHR was 0.82 in 40 years and 0.85$\pm$0.01 in 50- to 60- year-old group. The percentage of body fat increased with advancing years and the highest values were shown in 50 - to 60-year old group (skyndex value : 38.6$\pm$0.6, BIA value : 28.7$\pm$0.8<0.05). The prevalence of obesity was measured by bioelectrical impedance fatness analyzer (BIA), obdy mass index (BMI) and skinfold thickness were 17.0%, 24.0% and 78.0% respectively. Most subjects were in good nutritional status, but in the subjects aged 24~49, energy (89.3%), iron (93.3%) and vit. A (97.4%) intake were slighltyl lower than the RDA. Energy intake was slightly insufficient tot he 50-63year old subjects (88.6%) compared with RDA. It seemed that they restricted calorie intake for the weight control. The energy percentage of carbohydrate, fat and protein was 65 : 20 : 15, the result of which came closed to the recommended calorei composition. There were positive correlations between obesity and other variable such as age. number of childeren and physical indics.
This study was conducted on the nutritional status of 1,805 patients with allergic diseases (atopic dermatitis, allergic rhinitis, and asthma) aged 19 to 64 years according to their state of depression, based on the data from the Korea National Health and Nutrition Examination Survey (KNHANES). The Patient Health Questionnaire-9 (PHQ-9) was used to diagnose depression. Subjects with a score of 10 or more were categorized into the depression group (n=152) and the rest into the non-depression group (n=1,653). The results of this study were as follows: The proportion of women (75.7%) was higher than that of men (24.3%) in the depressed group (P<0.01). In terms of energy intake per 1,000 kcal, both men and women in the depressed group showed a lower energy intake than the non-depressed group and this intake was less than the estimated energy requirement (EER). The nutrient intakes of protein, calcium, phosphorus, iron, vitamin A, thiamine, riboflavin, niacin, folic acid, and vitamin C were below the estimated average requirement (EAR). Also, the intakes of fiber and potassium were less than the adequate intake (AI) (P<0.001). In the lifestyle parameters, the ratio of eating alone at lunch was 54.1%:33.1%, indicating that more than half of the depression group ate alone. In conclusion, it was observed that the nutritional status of allergic disease patients was imbalanced. The nutritional imbalance was due to insufficient energy intake and inadequate intake of nutrients, which was below the average requirements of vitamins and minerals and this was more evident in the depression group than in the non-depression group.
This study was performed to evaluate the effectiveness of food commodity supplementary program for low-income, living alone elderly people. The subjects were 57 low income aged females who lived alone in Bucheon city. The food commodity supplementary program lasted for 6 months, supplying one meal per day consisting with grains, meat, vegetables, dairy and fruit. Dietary intake, anthropometric measurements, and blood profiles were assessed. After 6 months of food commodity supplemented period, dietary intakes of protein(p<0.05), calcium(p<0.05), iron(p<0.05) and vitamin B(p<0.001) were significantly increased. The mean weight(p<0.05) and BMI(p<0.05) were increased, and the frequency of BMI over 25kg/m$^2$ was also raised from 54.4% to 59.7%. Serum concentrations of total protein(p<0.001) and albumin(p<0.001) were significantly increased, indicating improvement of protein status. The frequency of anemia was decreased from 45.6% to 26.3%. However, the proportion of dyslipidemia was increased. In general the stable food commodity supplementary program was effective to improve general nutritional status of the poor aged who lived alone, however, nutrient intakes still did not meet RDA for the elderly and the rates of obesity and dyslipidemia were increased. Therefore, local government should provide more active food support program and the selection of food items for commodity should be evaluated at regular intervals.
