Analysis of Dietary Calcium and Phosphorus Intakes and Contribution Rates of Major Dish Groups according to Gender, Age, and Region in Korea: Yeon Kyung Lee, Mi Kyeong Choi, Taisun Hyun, Eun Soon Lyu, Haeryun Park, Hee Kyong Ro, Young Ran Heo; Korean J Community Nutr 2020;25(1):32-47. Published online February 29, 2020; DOI: https://doi.org/10.5720/kjcn.2020.25.1.32

OBJECTIVES
Calcium (Ca) is an insufficiently consumed nutrient, whereas phosphorus (P) intake has exceeded the recommended intake level in Korea over the past decade. The purpose of this study was to analyze dietary Ca and P intakes and their contribution rate according to dish groups.
METHODS
A 24-hour dietary recall survey of 640 healthy adults (aged 19â€“69 years) was undertaken twice in four Korean provinces. Dietary Ca and P intakes and their rates of contribution from 31 major dish groups were analyzed and compared by gender, age group, and region.
RESULTS
The average Ca and P intakes of the subjects were 542.1 Â± 222.2 mg/d and 1,068.3 Â± 329.0 mg/d, respectively. The intakes of Ca and P as percentages of recommended nutrients intake (RNI%) were 71.7 Â± 29.8% and 152.6 Â± 47%, respectively, and the percentages under the estimated average requirement were 60.3% for Ca and 3.8% for P. The RNI% of Ca was not significantly different between males and females, but was significantly higher in subjects in the sixties age group than in other age groups and was significantly lower in the Korean capital than in other regions. The RNI% of P did not significantly differ by gender or age groups, but it was significantly higher in the capital than in Gyeong-sang. The five major dish groups contributing to Ca intake (contribution rate) were milks/dairy products 69.2 Â± 109.2 mg/d (12.6%), soups 55.6 Â± 69.6 mg/d (10.1%), stir-fried foods 53.1 Â± 70.7 mg/d (9.7%), stews 43.4 Â± 85.4 mg/d (7.9%), and kimchi 38.4 Â± 31.8 mg/d (7.0%). The five major dish group contributing to P intake (contribution rate) were cooked rice 160.7 Â± 107.1 mg/d (14.9%), stir-fried foods 88.5 Â± 89.4 mg/d (8.2%), soups 76.7 Â± 85.8 mg/d (7.1%), one-dish meals 63.3 Â± 94.4 mg/d (5.9%), and stews 62.6 Â± 89.3 mg/d (5.8%). The dish groups contributing to Ca and P intakes differed somewhat by gender, age group, and region.
CONCLUSIONS
Programs to improve the nutritional status of Ca and P intakes should consider the differences in Ca and P contribution rates by dish groups as well as by gender, age group, and region.

PURPOSE
The aim of this study was to analyze the association between sodium excretion and obesity for healthy adults in the Gwangju area.
METHODS
The participants included 80 healthy adults aged 19 to 69 years in Gwangju. The dietary intake and sodium excretion were obtained using the 24-hour recall method and 24 hour urine collection. The participants were classified into two groups according to the amount of urinary sodium excretion: (â‰¤ 141.75 mmol/dL, > 141.75 mmol/dL).
RESULTS
After adjusting for sex, age, smoking history, and income, the high excretion of sodium group was significantly higher for weight, body mass index, body fat mass, percent body fat, visceral fat area (VFA), waist circumference, hip circumference, and WHR. The energy and nutrients intake were significant after adjusting for sex, age, smoking history, and income. The LSE group had a significantly higher fat intake and Na/K intake ratio. The HSE group had significantly higher fiber intake, and K intake. As the amount of urinary sodium excretion increased, the risk of obesity before correction was 3.57 (95% CI: 1.13â€“11.25) times greater, and the risk of obesity of T3 increased significantly by 3.33 times (95% CI: 1.05â€“10.59). After correcting for sex and age, the obesity risk of T2 increased significantly by 4.23 times (95% CI: 1.11â€“16.06), and after correcting for sex, age, smoking history, and income, the obesity risk of T2 increased significantly by 6.81 times (95% CI: 1.44â€“32.19) the risk of obesity.
CONCLUSIONS
An association exists between sodium excretion and obesity in Korean adults. In this study, the high excretion of sodium group was obese and the risk of obesity was higher than the low excretion of sodium group.

A Study on Nursery School Teacher's Knowledge and Education of Nutrition Care in Gwang-Ju: Jin Song, Young Ran Heo; Korean J Community Nutr 2010;15(2):159-168. Published online April 30, 2010

Abstract PDF: This study was done to come up with a solution to effectively increase nutrition knowledge and education among nursery school teachers in the Gwang-ju metropolitan city area. The scores of teacher's nutrition knowledge were around the average of 9.4 points on a 15-point scale, which is about 63.1 points on a 100-point scale. When the types of subjects were compared, we recognized that the nursery school teachers with a college degree or those who have any training/education in nutrition had the highest scores in nutrition knowledge. Also, the nursery schools who have more than 101 children or public nursery schools had the highest scores in nutrition knowledge (p < 0.05). We can conclude that the knowledge of nutrition of nursery teachers is very lacking and it is not as high as it should be. In addition, we can also see that the dietary guidance and nutrition education time spent towards the children was very short. The lack of professional knowledge and education seems to be due to shortage of educational materials and because the teachers themselves lack the knowledge to pass on to their predecessors. In fact, even the teachers themselves feel the need to set up more nutrition-related education programs, obtain more guides and materials to teach them, as well as implement more organized and systemized teaching methods.

Factors Influencing the Consumption and Purchase of Functional Foods in Gwangju: Eun young Kim, Ki sang Ryu, Young Ran Heo; Korean J Community Nutr 2007;12(6):782-789. Published online December 31, 2007

Abstract PDF: The purpose of this study is to know about the consumption patterns of functional foods and their associated factors for contributing to the promotion of healthiness on Gwangju residents. The results obtained are summarized as follows: in terms of age, 35.9% of men (n = 78) and 52.3% of women (n = 128) are found in the age range of 45~54 which comprises the highest portion of age distribution. 49.5% of subjects had college education or more. In the occupation category, 33.3% of the men had business job positions, and 39.8% of women were in the unemployed (housewife) category. Stress relief was the most important factor to maintain good health. 76.2% of the subjects have experience in consuming functional foods. The main reason for taking functional foods was to maintain health. Information and reliability of effectiveness were considered when selecting functional foods. Purchasing functional foods was motivated by family members, relatives, and/or the subjects themselves. Functional foods were mainly purchased from pharmacies or health food stores. Regular exercise, drinking, periodical medical checkups, and eating score all are taken into consideration with the consumption of functional foods.77.9% of subjects recognized functions for functional foods purchased. 18.8% of subjects experienced side effects after intaking functional food. Therefore, functional foods should be managed by the government and nutrition education for consumers should be required to encourage them to choose functional foods more satisfactorily and safely.

Plasma Total Homocysteine, Folate and Vitamin B12 Concentrations in Patients with Coronary Stenosis: Hyeon Sook Lim, Young Ran Heo; Korean J Community Nutr 2005;10(6):963-970. Published online December 31, 2005

Abstract PDF: Recently elevated plasma homocysteine concentration is considered an independent risk factor for atherosclerosis and thrombosis with coronary artery disease. Folate and vitamin B12 are cofactors and closely related with metabolism of homocysteine. The purpose of this study is to evaluate the correlation between homocysteine and folate and vitamin B12 in patients with ischemic heart disease. Twenty-six patients, in whom coronary angiographic finding revealed more than 50% of stenosis at least in one coronary vessel were enrolled as the patient group, and thirty subjects, in whom angiographic finding revealed in not significant stenosis, but complained of chest pain, were selected as the control group. Fasting venous blood was obtained and measured the concentration of plasma total homocysteine, folate and vitamin B12 by high performance liquid chromatography and fluorescence detection method. We examined the correlation between homocysteine and folate and/or vitamin B12 in the control group and the patient group, respectively. Compared with the control group, the patient group had relatively higher plasma total homocysteine concentration (10.7 +/- 4.2 vs 9.6 +/- 3.5 umol/L), but showed no significant difference. Folate and vitamin B12 concentration are low in the patient group, but showed no significant difference between patient and control group. Plasma total homocysteine concentration showed negative correlation with folate and vitamin B12 in both the control group and the patient group, and showed significantly negative correlation in patient group {r = -0.550 (p<0.01) vs r = -0.609 (p<0.01)}. We knew that the plasma total homocysteine concentration were relatively elevated in patient group compared with the control group. Because plasma total homocysteine concentrations are closely negative correlated with folate and vitamin B12 in the patient group, folate and vitamin B12 supplement can lower the mortality and morbidity of ischemic heart disease.
