The decrease of bone mineral density gives rise to the outbreak of osteopenia and makes the possibility of a bone fracture. It makes health problems in society. It's very important to prevent osteopenia in advance. Also it's critical to prevent and take care of it in adolescent because it's the most developing period comparing to middle ages because that bone mineral density decreases. There are genetic, physical and enviromental factors that affect bone mineral density. Recently, a lifestyle and eating habits are also changing as the society atmosphere is gradually doing. This study have shown that 134 women and 75 men was chosen and responded to the survey of measuring bone mineral density and investigating a lifestyle. The measure of bone mineral density is to use Dual energy X-ray absorptiometry(DEXA) and check femoral neck and lumbar spine. Also questionaries was required to pre-made survey about their lifestyles. Analysis of data was done with SPSS program. Multiple regression analysis was used for the relation of bone mineral density, the heigths and BMI. The sample of Groups are checked for drinking, smoking or excercising about differences by t-test. The results of the experiments were; first, there is statistically significant differences in the comparisons between BMD and BMD. But there isn't any special correlation between drinking, smoking and BMD. Secondly, bone mineral density becomes low related to an intake of caffeine. Particularly, this is statically significant on women. Also there is statically significant correlation between femoral neck and quantity of motion for both men and women. Third, there is significant relation between eating habits and bone mineral density on women's lumbar spine. However, there is no significant relation between men's lumbar spine and women's one. Therefore, to prevent osteopenia, it's good to abstain from intaking caffeine within an hour after a meal. In addition, it's helpful to walk or run regularly and have a balanced meal.

Purpose: Cardiovascular disease is one of the major causes of death not only in Korea but also worldwide. Atherogenic index of plasma (AIP) has been extensively investigated, but studies on nutritional intake and eating habits are scarce. The purpose of this study was to analyze the general characteristics, dietary habits, and nutritional status of Korean adults based on their AIP values using data from the 2013-2015 Korea National Health and Nutrition Examination Survey. Methods: A total number of 3,040 adults in their 20s and 30s were included as study subjects. They were divided into quintiles according to their AIP values. Comparisons were then made among the general information, eating habits, and nutritional intake statuses of the groups. Results: The averages of AIP were different by age, obese status, education, occupation, alcohol drinking frequency, smoking, and exercise in men. As for women, the averages of AIP were different by age, obese status, education, occupation, alcohol drinking frequency, and smoking status. Except for high-density lipoprotein (HDL)-cholesterol, higher AIP values in men were associated with significant increasing trends in health indicators, including systolic and diastolic blood pressure, fasting blood glucose, insulin, hemoglobin A1c, total cholesterol, triglyceride, and low-density lipoprotein (LDL)-cholesterol. As for women, as AIP increased, systolic and diastolic blood pressure, fasting blood glucose, insulin, total cholesterol, triglyceride, and LDL-cholesterol showed significant increasing trends except HDL-cholesterol. HDL-cholesterol showed a significant decreasing trend as AIP increased in men and women. In the high AIP group of women, the frequency of breakfast was lower, whereas the frequency of alcohol beverage consumption was higher. Conclusion: Among young adults, the risk of arteriosclerosis was higher in obese, smoking, and non-exercise individuals. More frequent alcohol drink consumption in women is associated with a higher risk of arteriosclerosis. Therefore, weight and lifestyle management are necessary for the prevention of atherosclerosis among young adults.

Objectives : The purpose of this study was to explore attitude and belief about menopause and severity of menopausal symptoms according to menopausal status. This study conducted a cross-sectional assessment of the effects of depressive symptoms and the severity of trait anxiety on the severity of menopausal symptoms. Methods : Participants were all outpatients at the psychiatric outpatient clinic of Korea University Guro Hospital. All participants, aged 40 to 64, had depressive or anxiety disorders and were divided into the premenopause, perimenopause, premenopause, and postmenopause groups. Menopause Rating Scale(MRS) was used to measure the severity of menopausal symptoms. The attitude toward menopause was examined by a self-report questionnaire regarding menopause. Beck Depression Inventory(BDI) and State-Trait Anxiety Inventory(STAI) were used to assess depressive symptoms and anxiety. Results : The severity of menopausal symptoms was not different among the groups according to menopausal status. There was a significant correlation between a negative attitude toward menopause and the severity of menopausal symptoms. Patients with moderate to severe depressive symptoms and trait anxiety had more severe menopausal symptoms. Conclusion : Negative attitude toward menopause, depressive symptoms, and anxiety had a significantly negative impact on the severity of menopausal symptoms. The results of this study suggest that treatment to relieve depressive symptoms and anxiety and intervention to reduce negative attitude toward menopause are required. Further studies with larger sample size are needed to evaluate potentially effects of depressive symptoms and anxiety on severity of menopausal symptoms in middle-aged female psychiatric patients.

The purpose of this study is to clarify the definition of middle age, to compare the different perspectives about mid-life crisis, and to identify the variables that cause the mid-life crisis of men and women.. For this purpose reviewing literatures and emprical research were conducted. For the emprical research, Mid-life Crisis Scale, Mid-life Indentity Scale, Family Relation Scale. Health Scale and Religious Scale were developed. The Sample was selected form the men and women living in Seoul, whose age is from 40 to 59 , and whose last child is older than 13 years of age. Among 820 respondents 218 men and 442 women were finally selected as datum sources. The data were analyzed by the statistical method such as the factor analysis frequency distribution, percentile, ANOVA, Pearson's correlation and regression analysis. The main results were as follows; 1) Men and women experience mid-life crisis some extent. The mid-life crisis score for men is 33.60 and 35.0 for women. This implies women reveal significantly higher crisis than men. As for women's mid-life crisis. self-awaring age, education, income, husband's occupation, employment status of wife and occupational status of wife have a significant influence Expecially employment status of wife seemed to interact with sex, husband's occupation and educational level of wife. however status of child, family pattern, son's existence are not as important an influence on mid-life crisis. 3) Among the psychological variables, work identity and physical identity have the strong influence on the mid-life crisis of men and women, It implies that mid-life crisis si lower when one has higher work identity and physical identity. 4) Mid -life crisis of men and women is influenced significantly according to family relation variables and health variables. It reveals that the better one's family relations and health sate, the lower one's mid-life crisis is. However menopause and the years after menopause do not influence on the mid-life crisis of women. 5) Mid-life crisis of women differs significantly according to the kind of religion and religious activity. That is mid-life crisis of women is lower when she believes in Protestantism and Catholicism and participate in more religious activity. Mid-life crisis of men is not significantly influenced by religious variables. After all among the five categories of variables that related to mid-life crisis, psychological variables-especially work identity and physical identity are observed to have the strongest degree of significance.

The purpose of this study were to measure the body cathexis and the characteristics of middle-aged women groups segmented by their fashion orientation. Self-administered questionaire method was used. Seven demographic variables, 9 self-images, body cathexis were included as independent variables. Fashion orientation developed by Gutman and Mills was used. Data was collected from 369 Middle-aged women in Chonbuk Province. Frequencies, Percentages, means, standard deviation were caculated. ANOVA, cluster analysis, and discriminant analysis were used for data analysis. The results were as follows: 1. The body cathexis of the subjects were lower than capital city and increased according to age. 2. The self-image of the subjects were down-to-earth, modern, conventional, playing it safe, confident, stable, reserved and blending out into a crowd. The subjects with the self-image of being more sophisticated, confident, creative, stood out in a crowd, or complicated life style had higher body cathexis. 3. When the subjects were divided into segmentations according to their fashion orientation by cluster analysis, the best suitable number of groups was seven. The characteristics of seven groups were: *Fashion negatives showed low levels of fashion leadership and fashion interest, and medium level of importance of being well-dressed, and high level of antifashion attitudes. *Fashion neutrals showed medium levels of fashion leadership, fashion interest, and importnace of being-well dressed, and low level of antifashion attitudes. *Fashion uninvolveds showed low levels of fashion leadership, fashion interest, and antifashion attitudes. *Fashion followers showed high levels of fashion interest and importance of being well dressed, but low levels of fashion leadership and antifashion attitudes. *Fashion independents showed a littel bit high levels of fashion leadership, fashion interest, and importance fo being well-dressed, but low level of antifashion attitudes. *Fashion rejectors showed low levels of fashion leadership, fashion interest, and importance of being well-dressed, but high level of antifashion attitudes. 4. The seven groups segemented by their fashion orientation showed significant differences according to the educational levels, employment status, and total monthly income. Fashion leaders and fashion independents had higher educational level and monthly income, and involved more women with jobs. 5. Fashion leaders had self-image of being most sophisticated modern, diffenrent, creative, sociable, stood out in a crowd, and complicated life style. Fashion rejectors had self-image of being most down-to-earth, traditional, conventional, stable, reserved, blend into a crowd, and simplified life style. 6. The most effective variables among body cathexis, demographic variabls and self-images in discirminating fashion oreintation group differences were different-conventional, creativestable, and employment status. The discriminating power of above variables were high in very low in discriminating fashion negatives, fashion neutrals, and fashion independents, and the total discriminating power of these variables was 32.25%.

We performed a study to examine the association between diet quality and nonalcoholic fatty liver disease (NAFLD). Our study included 3,586 women aged 40-64 years who participated in the sixth Korea National Health and Nutrition Examination Survey. The study subjects were classified into the NAFLD group (n=816) and the normal group (n=2,770) using the hepatic steatosis index. The anthropometric indices, blood profiles, and dietary intake data of the subjects were obtained. The waist circumference, body mass index, and the serum levels of triglycerides, fasting blood sugar, HbA1c, and systolic and diastolic blood pressures were higher in the NAFLD compared to the normal groups (p<0.001, respectively). The intakes of protein (g/kg body weight, p<0.001), potassium (p<0.001), and vitamin A (p=0.006) were significantly lower in the NAFLD group. It was observed that the higher the total Korean Healthy Eating Index score, the lower the risk of NAFLD. A reverse relationship was shown between the NAFLD risk and the intakes of total fruits, total vegetables, vegetables excluding Kimchi and pickled vegetables, meat, fish, eggs and beans. Therefore, it is recommended that middle-aged women in Korea increase their intakes of fruits, vegetables, and foods high in protein for the proper management of NAFLD.

The purpose of this study was to obtain baseline data on nutritional management of women's bone health. We examined the bone mineral density (BMD) by ultrasound bone densitometer, anthropometric measurement and dietary intake to assess the nutrient intakes. The subjects were 102 Korean female college students (normal=59, bone disease group [osteopenia+osteoporosis]=43) and the mean age was 21.4 yr. Mean T-score (BMD) were -0.42 and -1.52 in normal and bone disease groups, respectively. Anthropometric measurement showed that 59% of the subjects were normal weight and bone disease group had lower value than normal group in majority of anthropometric index. The average energy intake was 1539.7 kcal, which was 73% of Korean EER. The subjects had lower vitamin C, folic acid, Ca and K intake than Korean RI independent of BMD. Bone disease group (1:2.05) showed significantly lower Ca:P ratio than normal group (1:1.86). Normal group had more intake frequency of milk and milk product than bone disease group. In relation to anthropometric index with T-score, significant correlations have been found in weight, PM, BFM, MM, TBW, SLM, FFM WHR, BMI and SMM. In relation to dietary factors with T-score, significant correlations have been found relating to intake frequency of milk and milk product. Our results indicate that for nutrients, ratio and balance may be more influential than intake for bone health in young women.

Purpose: The purpose of the study was to identify women's osteoporosis knowledge, concerns about osteoporosis factors, and health behavior as well as to examine the relationship between these variables. Methods: The participants were 394 women in the Jeonbuk area. The data were analyzed using a t-test, ANOVA, Duncan test, and hierarchical regression analysis with SPSS v. 24.0. Results: The score for osteoporosis knowledge was 6.21 points out of a possible 12, the score for concern about osteoporosis factors was 26.50 points out of a possible 40. The score for the health behavior was 57.26 points out of a possible 85. The knowledge showed significant differences according age (p < 0.01), income (p < 0.05), education level (p < 0.01), drinking milk in childhood (p < 0.05), health interest (p < 0.05), and osteoporosis information (p < 0.01). The concern showed significant differences according to age (p < 0.001), income (p < 0.05), health interest (p < 0.001), osteoporosis information (p < 0.001), family history of osteoporosis (p < 0.05), and calcium medications (p < 0.001). The health behavior showed significant differences according to age (p < 0.001), income (p < 0.01), drinking milk in childhood (p < 0.05), health interest (p < 0.001), osteoporosis information (p < 0.01), and calcium medications (p < 0.01). Regression analysis showed that the concern about osteoporosis factors was the most influential variable on health behavior, followed by health interest of the subjects, age, and the osteoporosis knowledge. Conclusion: Therefore, it is necessary to consider educational programs on increasing interest in osteoporosis according to the age and health for improving the health behavior to prevent osteoporosis.
