This study was conducted to examine factors with attendance in hyperlipidemia nutrition eduction program among 101 hyperlipidemic outpatients (38 males 63 females) at Samsung Medical Center We employed the Health Belief Model (HBM) as the theoretical framework The individual nutrition education and counseling program was scheduled with 4- half hour session sin 2 to 4 weeks intervals. Upon initiation of the program a trained dietitian surveyed HBM constructs and psychosocial factors. The following were included perceived susceptibility to cardiovascular disease(CVD) perceived severity to CVD percieved benefits to diet modification perceived barriers to persistence in maintaining therapy and self efficicacy and social support from family Sociodemographic data health factors stress level nutrition knowledge, and 24-hour dietary recall behavior were also surveyed All these data was analyzed according to the number of nutrition sessions attended The subjects were 55.9$\pm$9.4 year old and 24.6$\pm$kg/㎡ Sociodemographic factors were not associated with the number of nutrition sessions attended HBM constructs and psychosocial factors were significantly associated with the number of nutrition sessions attended. According to Spearman correlation coefficients. From stepwis regression analyses using HBM constructs as independent variables perceive barriers to persistence in maintaining diet therapy (negative) proved to be the strongest predictors for the number of nutrition sessions attended (partial R$^2$= 72.3%) followed by perceived severity to CVD and self efficacy (model R$^2$=76.6% The findings indicate that HBM constructs and psychosocial factors were closely associated with patient attendance It suggests that information and guidance to minimize patients perceived barriers to diet therapy might help to improve patients to scheduled appointments in nutrition education programs.

Nitrogen(N) concentrations of human milk in various fractions, such as total, protein, nonprotein, whey protein and casein were determined at 2-3 days, 1, 2, 4, 6 and 12 weeks of postpartum. significant decreases in total N, nonprotein N, protein N, whey protein N and casein N were found with time postpartum. Total nitrogen decreased from 401mg/dl at 2-3 days to 211mg/dl at 12 week. Whey protein nitrogen was found to contribute to the total nitrogen decrease with time. The percentage of nonprotein nitrogen was 13% in colostrum and 17-18% in mature milk. The proportions of whey protein and casein nitrogen were 55:45 at 2-3 days and 34:66 at 12 week postpartum. These determinations will provide the basic information on the variability of nitrogen components as lactation proceed.

The objective of this study was to obtain data on the safety-in-use of nano calcium as a dietary supplement by assessing its acute and subacute oral toxicities in female and male Sprague-Dawley rats. A single oral dose of 5,000 mg/kg of nano calcium did not result in mortality or significant changes in the general behavior and gross appearance of the internal organs of rats. For subacute toxicity study, nano calcium was administered orally at a dose of 1,000 mg/kg daily for 14 days. There were no significant differences in organ weights between control and treated groups of both sexes. Hematological analysis and blood chemistry revealed no toxic effects of nano calcium. Pathologically, neither gross abnormalities nor histopathological changes were observed. These results show that nano calcium possesses very low toxicity as indicated in a rat model.

Firefighters and police officers have the third highest prevalence of obesity among 41 male occupational groups in the United States (US). However, few studies have examined the relationship of firefighter working conditions and health behaviors with obesity. This paper presents a theoretical framework describing the relationship between working conditions, health behaviors, and obesity in firefighters. In addition, the paper describes a detailed study plan for exploring the role of occupational and behavioral risk factors in the development of obesity in firefighters enrolled in the Orange County Fire Authority Wellness Fitness Program. The study plan will be described with emphasis on its methodological merits: adopting a participatory action research approach, developing a firefighter-specific work and health questionnaire, conducting both a cross-sectional epidemiological study using the questionnaire and a sub-study to assess the validity of the questionnaire with dietary intake and physical activity measures, and evaluating the strengths and weaknesses of the body mass index as an obesity measure in comparison to skinfold-based percent body fat. The study plan based on a theoretical framework can be an essential first step for establishing effective intervention programs for obesity among professional and voluntary firefighters.

Objectives: This study investigated the relationship between the Korean healthy eating index (KHEI) and periodontal disease in the Korean adult population. Methods: The data used in the analyses were obtained from the seventh Korean National Health and Nutrition Examination Survey (2016-2018). Data were analyzed by chi-square tests and t-test. Multiple regression analysis was also performed to assess the association between KHEI and periodontal disease. Statistical significance was set at p<0.05. Results: Multiple logistic regression analysis adjusted for socioeconomic variables showed that medical and health behavior variables were significantly related to the KHEI 1 (<63.7, odds ratio [OR]: 1.23, 95% confidence interval [CI]: 1.03-1.46), KHEI 2 (63.7-79.9, OR: 1.14, 95% CI: 0.97-1.34), and risk for periodontal disease. Conclusions: The results showed a significant association between the KHEI and periodontal disease in the Korean adult population.

BACKGROUND/OBJECTIVES: The consumption of home meal replacement (HMR) is increasing among college students in Korea and China. In particular, Chinese college students studying abroad in Korea (CSK) show changes in their dietary behavior after migration, and HMR consumption for meal substitution is also increasing. This study was conducted to compare the HMR consumption behaviors and HMR development needs of CSK, Chinese college students in China (CSC), and Korean college students in Korea (KSK). SUBJECTS/METHODS: The subjects were 570 college students (180 CSK, 200 CSC, and 190 KSK) who had experience of HMR consumption. Data were collected by face-to-face survey in 2019 and analyzed using SPSS 25.0. RESULTS: The majority of the subjects purchased HMR to 'saving time' and 'preventing meal skipping'. Average purchase price per HMR was about 5,000 won for the CSK and KSK, and about 3,000 won for the CSC. The most important attributes when selecting HMR for the CSK and CSC were hygiene, freshness, and taste in that order, while for the KSK were taste, price, and hygiene. Rice was preferred by the KSK while grilled and fried dishes were preferred by the CSK and CSC. In terms of development needs, dessert and meat-based side dishes were highest in all three groups. The preferred food materials for more than 50% of the subjects of all groups were beef, chicken, pork, shrimp, and squid, and spinach and Chinese cabbage in the CSK, and onion in the KSK. CONCLUSIONS: This study shows more effort is needed to develop the healthy customized HMR for college students studying in Korea and China, and that focuses are placed by CSK on hygiene and freshness, by CSC on meat side dishes, hygiene, and price, and by KSK on snacks (as meal substitutes), taste, and price.

This is a convergence study to investigate the relationship between cereal intake level and food and nutrient intake in 218 Chinese middle aged women aged 40 to 65 years. Data were analyzed by ${\chi}^2$ test, ANOVA, correlation analysis and Jonckheere-Terpstra trend test using SPSS 22.0 program. The results of the study were as follows. The higher the level of cereal intake in the subjects, the lower were the rate of breakfast fasting (p for trend=0.000), overeating (p for trend=0.019), and eating out (p for trend=0.003). The intake of root and tuber crops(p for trend=0.008), meat(p for trend=0.043), pulses(p for trend=0.020), and light colored vegetables(p for trend=0.015) per 1,000 kcal of energy increased when the level of cereal intake was 6 to 9 units. Therefore, it is necessary to discuss and study for continuous education and improvement through the feedback so that the middle-aged women can take the cereal appropriately.

Objectives: We reviewed digital epidemiological studies to characterize how researchers are using digital data by topic domain, study purpose, data source, and analytic method. Methods: We reviewed research articles published within the last decade that used digital data to answer epidemiological research questions. Data were abstracted from these articles using a data collection tool that we developed. Finally, we summarized the characteristics of the digital epidemiological studies. Results: We identified six main topic domains: infectious diseases (58.7%), non-communicable diseases (29.4%), mental health and substance use (8.3%), general population behavior (4.6%), environmental, dietary, and lifestyle (4.6%), and vital status (0.9%). We identified four categories for the study purpose: description (22.9%), exploration (34.9%), explanation (27.5%), and prediction and control (14.7%). We identified eight categories for the data sources: web search query (52.3%), social media posts (31.2%), web portal posts (11.9%), webpage access logs (7.3%), images (7.3%), mobile phone network data (1.8%), global positioning system data (1.8%), and others (2.8%). Of these, 50.5% used correlation analyses, 41.3% regression analyses, 25.6% machine learning, and 19.3% descriptive analyses. Conclusions: Digital data collected for non-epidemiological purposes are being used to study health phenomena in a variety of topic domains. Digital epidemiology requires access to large datasets and advanced analytics. Ensuring open access is clearly at odds with the desire to have as little personal data as possible in these large datasets to protect privacy. Establishment of data cooperatives with restricted access may be a solution to this dilemma.

The number of patients from Middle Eastern Arabic countries is steadily increasing in respect to the South Korean government's medical tourism strategies. Word of mouth is one of the main determinants concerning the Middle Eastern Arab patients' medical tourism destination. Further, patients' satisfaction affects repurchase and revisit intention. This study aimed to measure the level of Middle Eastern Arab patients' satisfaction, and to measure the effect of different medical factors on satisfaction in such patients who are seeking medical attention in South Korea. A 110 Middle Eastern Arab patients who visited South Korea for medical purposes participated in our survey between November, 2016 and April, 2017. All factors had a high mean (${\geq}4.24$; ${\geq}84.8/100$) except for one factor (hospital halal meals (3.82; 76.4)). To identify factors influencing participants' overall satisfaction we used multiple regression analysis. Physicians, interpreters, and halal meals were the main factors influencing overall Middle Eastern Arab patients' satisfaction. Physicians and interpreters in Korea are recommended to be oriented to basic Islamic beliefs and Middle Eastern Arab patients' behavior. Daily communication, such as speaking directly to the patient, limiting important issues to two or three at a time, and translating sentence by sentence, could help to improve Middle Eastern Arab patients' satisfaction. Enlisting Middle Eastern nutrition specialists in medical institutions in South Korea may substantially improve non-medical services satisfaction such as halal food and dietary restrictions.

The objective of this study was to compare nutrients intake, health indices, and prevalence of chronic diseases by occupation in middle-aged men, using results from National Health and Nutrition Examination Survey. The subjects were divided into two groups by their occupation (Office worker (OW) and Agri-fishery worker (AFW)) and their percentages were 75.5% and 24.5% respectively. In health-related factors, drinking rate was higher in OW (p<0.001), while smoking rate was higher in AFW (p<0.001). Walking and strength exercise were both higher in OW group. In dietary behavior, the rate of skipping breakfast and eating out was higher in OW (p<0.001). Food supplement usage were consumed by OW more than AFW (p<0.001). Daily energy intake was higher in AFW (p<0.05). There were significant differences in nutrient density per 1,000 kcal of minerals and vitamins between the two groups (p<0.05~p<0.001), except calcium, potassium, vitamin A and thiamin. In body weight, BMI, waist circumference and blood pressures, OW was higher than AFW (p<0.05~p<0.001). Whereas, HDL and LDL-cholesterol were higher in AFW (p<0.001). The prevalence of diabetes was higher in AFW (p<0.001). The results of this study can be used as data to establish nutrition and health strategies for occupation in middle-aged men.
