High insulin level is known to be a risk factor of coronary heart disease. High insulin level with normal glycemic control is known to be an indicator for insulin resistance. This study was aimed to find out the influencing factors for the fasting serum insulin levels in elderly females with normal glycemic control. One hundred thirty-eight older females aged over 60 years without diabetes medication and high blood HBA1c level were examined on the serum fasting insulin concentration, anthropometry and asked about nutrient intake and exercise habits. The elderly were categorized into 3 group according to the fasting insulin level. The high insulin group was in a state of hyperinsulinemia. Except vitamin C, the nutrient intakes showed no difference according to fasting serum insulin level. But the intakes of calorie and protein per kg body weight were significantly lower in the high insulin group. The intakes of most nutrients except vitamin B$_1$, C and niacin were lower than the korean RDA in all the insulin group. Especially, the intakes of vitamin B$_1$ and Ca were below 75% of the korean RDA. Weight, BMI, body fat percent, body fat mass and fat-free mass, circumferences of waist and hip, WHR of elderly females were significantly higher in the group with the highest insulin level. The body fat percent in the highest insulin group was 35.8%. showing a state of obesity. The high insulin group showed higher proportion of low exercise frequencies per week and short exercise duration. Therefore, the mean energy expenditure for exercise were lower in this group, showing a state of very low exercise activity. Age and waist circumference in elderly females could explain to the 14.5% variances of the fasting insulin level according to multiple stepwise regression. It can be concluded that aging and central body fat deposition influence independently the serum fasting insulin level in elderly females with normal glucose level.

Nowadays, interest in health care is increasing due to Coronavirus (COVID-19), and a lot of people are doing home training as there are more difficulties in using fitness centers and public facilities that are used together. In this paper, we propose a personalized exercise recommendation algorithm using personalized propensity information to provide more accurate and meaningful exercise recommendation to home training users. Thus, we classify the data according to the criteria for obesity with a k-nearest neighbor algorithm using personal information that can represent individuals, such as eating habits information and physical conditions. Furthermore, we differentiate the exercise dataset by the level of exercise activities. Based on the neighborhood information of each dataset, we provide personalized exercise recommendations to users through a dimensionality reduction algorithm (SVD) among model-based collaborative filtering methods. Therefore, we can solve the problem of data sparsity and scalability of memory-based collaborative filtering recommendation techniques and we verify the accuracy and performance of the proposed algorithms.

Purpose: This study was to investigate lifestyles and identify factors influencing the bone mineral density (BMD) among employees in a community. Methods: Data were collected from 199 employees. Their lifestyles and BMIs were measured with a self-report questionnaire. As for their BMDs, their calcanei were measured with Quantitative Ultrasound. Results: Assessing their BMDs with reference to the WHO standards, 52.8% of the subjects' calcaneus BMDs were normal and 44.2% showed osteopenis, 3.0% showed osteoporosis. Age (odds ratio=1.05, p=.029), exercise (odds ratio=.31, p=.006) and the number of eating meals per day (odds ratio=1.97, p=.046) were significant factors influencing the subjects' BMDs. Conclusion: Strategies to emphasize exercise and dietary habits in employees are important for improving their bone mineral density. Programs for improving bone mineral density based on life cycle need to be developed.

The purpose of this study was to investigate the relationship between the dietary attitude and health on the stress status of office - workers in Seoul. This research was conducted on 389 office workers (224 males and 165 female). In relation to stress, it was found that the degree of stress as an office workers was ′slight′ and much for 45.2% and 40.6%, respectively, of the study population. Consequently, most office workers were found to be under stress. The amount of food intake under stress was found to be ′reduced′, unchanged and increased in 38.3, 37.0 and 24.7%, respectively, of those surveyed. The preferred foods when under stress were found to be alcoholic and non-alcoholic beverages, in 57.6% of cases, which was the highest proportion regardless of age, sex, marital status, occupation and educational level. The desired taste when under stress was found to be ′hot′ and sweet in 34.7 and 26.0%, respectively. As to the feeling after food intake, 51.7% responded that food intake was not useful for the relief of stress, which was the highest proportion and many salaried females worried about weight gain. With regard to the relationship between stress, health and nutrition, 69.9% of office workers responded that they thought the relationship of these factors was very high. As for the greatest cause triggering stress, 50.3% responded "due to workplace and job". The best method for relieving stress was to do exercise, with a 30.1 % response, The average score for the degree of stress and tension was 7.2, with 64.0% of office workers having an average level between 6- and 9. The degree of stress was higher for females than males, for unmarried salaried and hot-tempered persons. Those not doing exercise were subject to the highest levels of stress, and those a having sufficient sleep were found to be subject to less stress. Those interested in their health were found to have a good condition and lower levels of stress. In correlation with eating habits, stress, the degree of tension and personality, the F-value was found to be 43.505 (p<0.01), with an explanatory power of 0.294 (29.4%), indicating significant differences. This means that office workers with higher degrees of stress and tension tended to have poorer eating habits. Since bad eating habits have an adverse effect on both the state of physical health and individuals emotional development, for the purpose of correctly managing stress, office workers should make efforts to practice good eating habits.

The purpose of this study was to figure out the characteristics of dietary habits and lifestyles related to the development of insulin resistance syndrome(IRS). The participants in this study were 595 adults with one or more abnormal data from a health examination and 215 normal adults. When IRS was defined as a condition in which the subjects have 2 or more abnormalities among obesity, hyperlipidemia, hypertension and hyperglycemia, the prevalence rate was 37.8%. We classified the 595 adults by the number of components of IRS components they had, the higher age and obesity index they had. Total cholesterol and glucose levels in the blood were also positively related to the number of IRS components. IRS subjects tended to practice less habitual drinking and more exercise and weight control. Coffee consumption and dining out frequency were also lower in the IRS group. An analysis of food habits by odds ratio indicated that total food score was better in the IRS group. However, it appeared that food habits such as \"frequent snacking\" and \"never rejecting offered foods\" need to be improved in IRS subjects. Other undesirable food habits were related to the consumption of eggs, dairy products, fried foods, garlic and onion. Dietary intake of Ca, Fe, riboflavin, Vit A, and energy were less than 75% of the Korean recommended allowance for more than half of the subjects. Nutrient intake was lower, Ca/P ratio from food intake was worse in the IRS group. Our results indicated that nutrition counseling for IRS need to be focused on balanced food intake to supply sufficient amount of each nutrient.nt of each nutrient.

This study investigated the correlations among the health consciousness, nutrition knowledge, dietary habits and nutrition attitudes of school teachers. The subjects of this study were 75 male and 152 female leachers in elementary and middle schools in Masan city. The survey was conducted by using a questionnaire. Even though the average body mass index (BMI) and the obesity index were normal in both male and female subjects, 33.3% of the male subjects were overweight/obese, while 18.5% of the female subjects were underweight, according to the obesity index. The food components of most concern during mealtime were (in order of importance) salt, MSG and cholesterol by male subjects, and salt, fat and MSG by female subjects. The subjects considered self-relaxation as the most important factor in maintaining optimal health status, followed by resting, bathing or use ova sauna, moderation in diet, exercise, decreasing alcohol intake, and no smoking. Newspapers/magazines and TV/radio were the primary sources of nutrition and health information of the subjects. As the degree of health consciousness increased, scores of the dietary habits and nutrition attitudes increased. Nutrition knowledge scores and nutrition altitudes scores increased with subjects'increased level of perception of the importance of acquiring nutrition knowledge and nutrition information. There was a highly significant correlation between the degree of health consciousness and dietary habit score (${\gamma}$ : 0.3, p<0.001). The degree of health consciousness was also significantly correlated (${\gamma}$=0.6, p<0.001) with nutrition attitudes scores. But the correlation between the degree of health consciousness and nutrition knowledge was not statistically significant. The degree of the perception of the importance of nutrition knowledge showed a positive correlation with nutrition attitude (${\gamma}$:0.4, p<0.001) and dietary habit (${\gamma}$:0.3, p<0.001). The degree of perception about the importance of nutrition knowledge and nutrition information was positively correlated with nutrition knowledge (${\gamma}$:0.2, p<0.001) and nutrition attitudes (${\gamma}$:0.3, p<0.001).

This study focused on the yearly-dietary habits, nutrition status, and health of female students residing in Seoul. A number of classes were assess based on their dietary behaviors in oder to attempt to determine differences in their attitudes to nutrition, according to age. The students of class 2011 (sophomore) ate meals more regularly than the female students of the 2008 class (p<0.05). It was found that sophomore female students of class 2008 consumed higher than average nutrient intake. Sophomore female students of the 2011 class consumed lower than average vitamin $B_2$, C, Ca, and Fe intakes. Folic acid in take was lower than average in both groups. Phosphorus and sodium intakes in both groups were excessive (p<0.05). When surveyed, sophomore female students of the 2008 class believed that the most important thing for health was exercise, whereas students of class 2011 believed that nutrient intake was the most important factor (p<0.05). Female students of the 2008 class exercised 1~2 times a week generally, whereas students of class 2011 exercised three times (43.2%) (p<0.05). Therefore, it is necessary to study changes in dietary habits and health status according to the age of students, and develop specific nutrition education programs for female students.
