Objectives: The aim of this study was to investigate dietary intakes and nutritional status among Uganda primary school children from two selected schools in urban and rural areas. Methods: Data were collected from 350 pupils (6-14 years) in Mpigi district, Uganda. All participants were offered a school lunch meal (usually maize porridge and boiled beans). Dietary survey was conducted in October 2016. Data for dietary intake levels were collected by the 24-hour recall method with trained school staffs. The data were converted into nutrient intakes using the CAN-Pro 5.0 Program and compared with KDRIs to evaluate the nutritional status of the subjects. Diet quality indexes such as nutrient density, nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and index of nutritional quality (INQ) and a diet diversity index such as diet diversity score (DDS) were calculated to evaluate nutritional status among subjects. Data were analyzed using SPSS statistical programs. Results: Results show that the intakes of most nutrients were significantly different by schools. The nutritional status of micro-nutrients was very low in both schools according to analysis of nutritional indexes such as NARs and INQs. Students from both schools should improve intakes of micro-nutrients related to child growth such as calcium, Vitamin B₆, zinc and folate. According to the analysis of dietary diversity, there was difference in dietary patterns by schools presumably due to their locations. Conclusions: This suggests that current meals could not provide adequate nutrients for the subjects and urgent nutrition interventions for school food services are needed to improve their nutritional well-being. New foods supplements based on local cuisine are also needed to ensure dietary diversity and sustainable development plans.

Purpose: The purpose of this study was to estimate intakes of macronutrients and antioxidant vitamins according to the Hansik consumption rate among Korean adults. Methods: Using data from the 2007~2012 Korea National Health and Nutrition Examination Survey, a total of 33,069 subjects aged over 19 years old were included in this study. We estimated individual daily Hansik consumption rates and intakes of macronutrients and antioxidant vitamins, including vitamin A and its subgroup such as retinol, ${\alpha}$-carotene, ${\beta}$-carotene, and ${\beta}$-cryptoxanthin, vitamin C, and vitamin E, by linking food consumption data with the nutrient and antioxidant vitamin database of commonly consumed foods. Results: Around 75% of subjects consumed Hansik in over 75% of their daily total consumed food. The most frequently consumed Hansik was cabbage kimchi (1.57 times/day), followed by multigrain rice (0.86 times/day) and white rice (0.80 times/day). The household income level and education level was inversely associated with the Hansik consumption rate. There was a positive relationship between Hansik consumption rate and vitamin A, ${\beta}$-carotene, ${\beta}$-cryptoxanthin, and vitamin C intakes. On the other hand, Hansik consumption rate was inversely associated with energy and fat intake. Conclusion: The results of this study suggest that Hansik consumption could provide more antioxidant vitamins and less energy and fat. Thus, further research will be needed to analyze the association between Hansik and health effects.

Purpose: This study examined the association between fruit and vegetable intake and mental health in Korean adolescents. Methods: This study used the data from the 2014-2017 Korea Youth Risk Behavior Survey, a national cross-sectional survey on 137,101 boys and 130,806 girls aged 12-18. Fruit and vegetable intake was assessed based on the frequency of consumption. The outcome variables were the perceived happiness, perceived stress, depressive symptom and suicidal ideation over the previous 12 months. Logistic regression models were used after adjusting for the demographic, life style and other dietary factors. Results: Only 34% and 29% of Korean adolescents consumed fruits more than 5 times/week and vegetables more than 2 times/day, respectively; whereas 37%, 25% and 12.2% of Korean adolescents had perceived stress, depressive symptom and suicidal ideation, respectively. After adjusting for the confounding variables, the greater consumption of fruit and vegetable were all associated with a higher odds of perceived happiness; the adjusted odds ratios (AORs) (95% CI) were 1.53 (1.46-1.60) in boys and 1.82 (1.73-1.90) in girls who consumed fruit ≥ 5 times/week, and 1.65 (1.54-1.76) in boys and 1.62 (1.51-1.72) in girls who consumed vegetable ≥ 2 times/day. In contrast, the consumption of fruit or vegetable were all significantly associated with a lower odds of perceived stress, depressive symptom, and suicidal ideation; the AOR (95% CI) were 0.70 (0.67-0.73), 0.88 (0.84-0.93), and 0.78 (0.73-0.83) in boys who consumed fruit 3-4 times/week, and 0.71 (0.67-0.76), 0.88 (0.81-0.94), and 0.68 (0.62-0.74) in boys who consumed vegetable 5-7 times/week. Similar associations of fruit or vegetable consumption with perceived stress, depressive symptom, or suicidal ideation were found in girls. Conclusion: These findings provide evidence that increasing fruit and vegetable intake is important for better mental health among adolescents.

The purpose of this study was to examine the question of whether there is any difference in dietary habits, climacteric symptoms, and general health characteristics of middle-aged women according to food supplements (FS) use. A total of 745 midlife females participated in a face-to-face interview conducted by qualified interviewers, which guaranteed a higher quality of data collection. Three levels of FS use were defined: None, Single, and Multi for 0, 1, and 2 or more types of FS use, respectively. None, Single, and Multi accounted for 33.56%, 33.29%, and 33.15% of total subjects, respectively. FS users (Single and Multi) exerted more interest in FS and were more likely to believe that FS is helpful for health promotion and amelioration of climacteric symptoms than None (P<0.0001). Self-perceived health status of Multi was lower than that of None, but not different from Single (P<0.05). Factor analysis extracted three factors for dietary habits: regularity, variety and moderation, and four factors for climacteric symptoms: emotional, physical, psycho-somatic, and hot flash. The factor scores for dietary variety as well as emotional, psycho-somatic, and hot flash symptoms were higher for FS user than for None (P<0.01). Single reported more frequent family meals compared to None. Findings of the present study elucidated potential links between the level of FS use, dietary habits, and climacteric symptoms of middle-aged women, suggesting a possible scenario: the greater the climacteric symptoms a woman perceives, the more likely the woman will adopt FS use, the greater the efforts toward dietary improvement, such as dietary variety. Based on that, in this study, more peri-menopausal women belonged to Single and Multi; further investigation on the association between FS use, dietary quality, and climacteric symptoms in conjunction with menopausal status may be needed.

This study was carried out to investigate health status and nutritional status based on dietary intake and food habit of elderly women in rural area of Keyonggi Province. The subject of this study were 133 elderly women aged 60 and over and interviewed with a questionaire. Main result was as follows : 1) Health score based on modified Cornell Medical Index, CMI(45 out of 195 items) was the average $29.1\pm6.8$ and was not significantly different with family size educational level and farmwork participation. In age, 44.0% of the subject in 60~65 years old was low score of CMI(11~25), but 50% of the subject in older than 80 years old was high score(33~44). The subject with disease was 82% and disease of musculoskeletal system was main type. 2) Dietary intake data obtained by a semiquantitative food frequency questionaire showed the average daily intake of energy, protein, Ca, retinol and riboflavin was lower than RDA Daily energy, protein and Ca intake was individually 84%, 67% and 55.1%. It was retinol that was the least sufficient as 49.1% of RDA. 3) The relation between CMI score(divided into three level : low, middle and high) showed low level was significantly different with others according to daily intake of energy, protein, retinol, thiamin, riboflavin and ascorbic acid. The correlation between CMI score and all nutrient intake were highly significant (p＜0.001), thus we knew that health status was affected importantly by nutrient intake. 4) Family size, educational level and age showed not significant correlation with all nutrient intake. 5) In food habit, 84.8% of the subject had regular mealtime and 14.4% were skip meal sometimes. The main reason of skip meal was a poor appetite. Preference for salty taste of subject was insufficiently salty of somewhat salty. Preference for fishes and meats showed the subject consumed fishes more than meats, but 23.5% of the subject didn't consume both. The subject eaten supplement was 38.3%.

The study was conducted to investigate children's attitudes toward food advertisement on children's television programs. A total of 868 subjects were selected from two KangNam and KangBook elementary schools (4, 5, 6th graders). First, it was reviewed food ads. On children's television program on 3 channels between 5∼7 pm from April to July in 1997. Among the total television commercials, 58% were food product ads.. Among the advertised food, the largest number of ads. was for beverages (21.6%) and the next was for cookies (19.7%), followes by sharbet and ice cream (19.5%), fast food (12.4%), cereal (5.5%) and milk and milk products (2.9%). This review revealed that the mostly advertised food are high in calorie, fat and sugar. Secondly, it was conducted a survey. The results of the survey were as follows: weekly average TV watching hours per child: 13.5. 50.8% of the children watched children's program on TV. 83.9% of the subjcts answered that they get their information about new food through TV ads.. 59.2% of children tried to buy the food advertised on TV program. The relationship between TV food ads. and health, 49.4% of the children answered that advertised food were not good for one's health. When we asked them to choose between advertised and non-advertised food, they preferred the advertised ones, such as cookies, beverages, fast food restaurants and cereals (p＜0.001). The results of this study suggest that children's purchasing and selecting of food were influenced by TV food advertisement. Therefore, education is needed which will help children's make responsible, informed consumers choices.

The time 18 months after birth is very important for the prevention of early childhood caries because this time is proper to assure the completion of weaning and to perform the diet counseling, and caries process is initiated or actively aggravated under the total influence of feeding pattern from this period. For the purpose of examining the infection status of Streptococcus mutans and Lactobacillus of 18 month old infants and their mothers, and analyzing the correlation between infection status versus various caries-risk factors, this study was performed on the 60 infants of 18 months old and their mothers through the microbiological screening of saliva samples and direct questionnaire to mothers about the caries risk factors. And the results were as follows, 1. The higher the mother's infection level of S. muntans, the higher the infant's infection level and transmission rate. 2. Compared with non-caries group, higher infection level of S. mutans in both infants and mothers and transmission rate were revealed in caries group. 3. The higher the infant's infection level of S. mutans, the higher the caries prevalence and deft values, the less the monthly income of the parents, the longer the period of breast feeding, and the higher the consumption rate of sugared snacks. 4. Most of Lactobacillus infected infants were revealed to be infected also with S. mutans and to have caries. 5. The higher deft value, less parents' monthly income, more frequent daily nursing and more irregular snacking patterns were found among Lactobacillus infected group compared with not-infected group.

The purpose of this study was to investigate convenience foods at convenience stores, by examining consumption patterns, as well as the degree of checking food-nutrition labeling. In this study, 208 workers in Busan in their 20s or 30s were surveyed using 1:1 interview questionnaires. The weekly usage frequencies of cup-ramyeon, gimbap, ramyeon, and sandwiches were 41.0%, 39.4%, 32.7%, and 19.0% respectively. The usage frequency of convenience foods was 12.0% for 'over 5 times/week', 23.0% for '3~4 times/week', 31.7% for '1~2 times/week', 29.8% for '1~2 times/month', and 3.4% for zero usage. Workers in their 20s showed a significantly (P<0.05) higher rate in the '3~4 times/week' as well as '1~2 times/week' intervals than workers in their 30s. Single people showed a significantly (P<0.01) higher rate than married people. Workers in their 20s showed a significantly higher score for the '3~4 times/week' as well as '1~2 times/week' intervals (P<0.05). The mean score of checking food labeling was 4.02/5.00 for the manufacturer's date, or expiration date, 3.23/5.00 for weight or volume, 2.99/5.00 for cooking method, and 2.85/5.00 for storage method. Females showed significantly (P<0.01) higher rates for checking the manufacturer's date or expiration date, as well as source of the raw material. Single workers showed significantly (P<0.01) higher rates for checking the manufacture's or expiration date as well as storage method. The mean score for checking nutrition labeling was 3.06/5.00 for calories, 2.84/5.00 for trans fat, 2.80/5.00 for sodium, and 2.76/5.00 for cholesterol. Females showed a significantly (P<0.01) higher rate for six of 10 items. Workers in their 20s showed a significantly (P<0.05) higher rate for four of 10 items. Expert officials showed significantly higher rate for six of 10 items (P<0.05) and two of 10 items (P<0.01), respectively.

Purpose: The aim of this study was to examine the association of food security with the total and individual flavonoid intakes among Korean adults. Methods: Study subjects were 13,454 men and 19,563 women aged 19 years and older who participated in the 2007~2012 Korea National Health and Nutrition Examination Survey. Subjects were classified into food-secure and food-insecure groups using the answers to a self-reported question on food sufficiency of subjects' household. The total and individual flavonoid intakes were calculated by linking 24-h dietary recall data of subjects with a flavonoid database. Mean differences in dietary outcomes by food security status, and major food sources of total flavonoids were examined. Results: In this cross-sectional study, 5.8% of male adults and 6.6% of female adults were in food insecure households. Mean daily intakes of total flavonoids, flavonols, flavones, flavanones, flavan-3-ols, isoflavones, and proanthocyanidins were significantly lower in food-insecure groups than food-secure groups among both male and female adults. The differences were maintained in total flavonoids, flavones, flavanones, and flavan-3-ols after adjusting for total energy intake. Mean intakes of fruits and vegetables were significantly lower in food-insecure groups and the total flavonoid intake from fruits and vegetables was also significantly lower in food-insecure groups. The major food sources of total flavonoids were apples (20.7%), mandarines (12.0%), and tofu (11.5%) in the food-secure group, and apples (14.9%), tofu (13.3%), and mandarines (12.6%) in the food-insecure group. Conclusion: This study showed that food insecurity was associated with lower intakes of flavonoids and reduced intakes of fruits and vegetables in a representative Korean population.

Purpose: This study was conducted to evaluate nutrition intake and diet quality according to carbonated drink consumption in male adolescents (middle-school students = 480, high-school students = 417). Methods: We analyzed data from the combined 2007~2009 KNHANES (Korean National Health and Nutrition Examination Survey). Subjects were divided into two groups, the LCDI (low carbonated drink intake (< 1 time/week), n = 362) group and the HCDI (high carbonated drink intake (${\geq}1$ time/week), n = 535) group, according to carbonated beverage consumption. Nutrient and food group intake, NAR (nutrient adequacy ratio), and MAR (mean adequacy ratio) were analyzed using data from the 24-recall method. Results: Intake of plant protein, vitamin C, plant calcium, phosphorous, and potassium was significantly lower in the HCDI group, compared with the LCDI group. Percent of RNI (recommended nutrient intake) of vitamin C and phosphorous was significantly lower in the HCDI group, compared with the LCDI group. Percentage of subjects who consumed under EAR (estimated average requirement) of protein and vitamin C was significantly higher in the HCDI group, compared with the LCDI group. The NAR of phosphorous was significantly lower in the HCDI group, compared with the LCDI group. Food intakes from potato and starches, pulses and vegetables were significantly lower in the HCDI group, compared with the LCDI group. Conclusion: Consumption of carbonated drinks decreased the diet quality, including calcium, potassium, protein, and vitamin C. Therefore, nutrition education relating to consumption of carbonated drinks is required for male adolescents in order to maintain healthy dietary habits.
