Anti-aging is one of the key words to have characterized Korean society, and Korean adults in their 40s and 50s are very interested in this word. In this study, their cognitive ages and body images which are expected to have been influenced by anti-ageing were determined and correlation between them was examined. A survey was conducted and 368 of 500 questionnaires were used in data analysis. Data were analyzed by descriptives, factor analysis, reliability analysis, correlation analysis, and multiple response analysis through SPSS 12.0. The results are as follows. First, the cognitive ages of Korean adults in their 40s and 50s showed to be 37.5 years old which are 9.1 years old younger than their average actual ages. Second, their attitudinal body images appeared to be composed of appearance orientation and appearance evaluation, and appearance orientation represented to be a little higher than appearance evaluation. In addition, it showed that the correlation between cognitive ages and the attitudinal body images was low and negative. Third, people in their 40s and 50s revealed to think good health and impression as ideal body images. It was found that they regarded a face as the most important body part for ideal body images and were sensitive of their weight. Forth, correlation between cognitive ages and variables of ideal body images was identified to be significant in 4 variables which are slender, shapely and slim figure and good body proportions. In conclusion, it was shown that Korean adults in their 40s and 50s recognized themselves to be 9.1 years old younger and, the younger they perceive themselves, the younger body images they want. Also, it could be confirmed that anti-ageing is a megatrend in Korean society.

This study was conducted to compare the perception and fast food usage patterns of adults classified by age in Busan. The survey was conducted from April 15 to June 15, 2017 by questionnaires and the data were analyzed using SPSS 24.0 Overall, 74.1%, 58.1%, 40.7%, 20.3%, 29.7% and 17.9% of individuals in their 20s, 30s, 40s, 50s, 60s and 70s, respectively, consumed fast foods more than once a week. Additionally, 66.0%, 52.5%, 25.7%, 16.0%, 22.9% and 11.7% of individuals in their 20s, 30s, 40s, 50s, 60s, and 70s, respectively, preferred fast foods. There was a significant difference in the basis for choosing menu among the groups, with 'preference' and 'price' being most important to those in their 20s and 30s, on the other hand 'preference' and 'companion' being most important to members of other age groups. As their age increased, individuals spent less money on fast food. Overall, 81.5%, 59.9%, 50.0%, 40.1%, 46.3%, and 28.4% of individuals in their 20s, 30s, 40s, 50s, 60s and 70s thought that fast food was a suitable substitute for a meal. Age affected the substitutability of fast food for a meal (P<0.001). Additionally, the ratio of individuals in their 20s and 30s that skipped breakfast was higher than in other age groups. In addition, age showed a significant positive correlation with obesity and dietary attitude, whereas it showed a negative correlation with nutrition knowledge, use frequency, perception degree and preference. Nutrition knowledge and dietary attitude showed no relationship with preference. These results imply that a nutrition education program should be developed and conducted to induce subjects to manage their dietary habit and develop healthier dietary patterns.

This study conducted a survey to analyze awareness, preferences, and the current state of consuming environmentally friendly organic food while eating-out in 435 adults aged 20 and above in Daegu, Korea. Most subjects (95%) showed awareness of environmentally friendly organic food, and 88.5% of subjects answered environmentally friendly organic food is 'needed'. The percentage of eating out for families was 58.9%, and 49.0% of subjects said they eat out one to three times per month on average. In addition, subjects preferred a price range between 10,000 and 20,000 won per person when eating out, and they mostly favored Korean restaurants when ordering environmentally friendly organic food. Analysis of awareness of environmentally friendly organic food showed that among 'health' factors, 'environmental' factors, 'social' factors, and 'dietary essential' factors, 'health' factors showed the highest percentage for awareness. A survey on preferred foods by gender showed that both genders preferred vegetables the most. The results show that subjects in their 20s and 30s favored vegetables and fruits while subjects in their 40s preferred vegetables and grain animal products. Analysis of preferred types of environmentally friendly organic foods showed that men preferred polished rice while women preferred brown rice. Subjects in their 20s and 30s preferred strawberries, whereas those in their 40s preferred cherry tomatoes and those in their 50s and above favored tomatoes (p<0.001). Among root and tuber crops (63.4%), sweet potato was the most preferred. Among fruits, subjects preferred apples while among special crops, they most preferred oyster mushrooms; both genders preferred Korean beef. The most preferred livestock product of subjects in their 20s was pork, whereas subjects in their 30s preferred Korean beef. Subjects in their 40s preferred Korean beef and pork in the same proportions, whereas subjects in their 50s and above favored eggs the most.

The purpose of this study was to analyse craniofacial shape by 3D scanner for Korean adult head shape by age group. The heads of 836 adults were measured by 3D scanner, and the 25 obtained measurements were analyzed by statifical methods. The results can be summarized as follows. 1. From the basic statistical data analysis, the vertex-tagion and the length between the pupils were the longest in the subjects in their twenties, and decreased in elderly groups. 2. According to the analysis of the craniofacial proportion, the typical adult Korea head type was short-headed. 3. Statistically noticeable differences were found in the ectocanthion- opistcranion by the measurement of the left and the right sides of face in the age groups of the 20s, 30s, 40s, and 50s. 4. The order of factor analysis was as follows: the horizontal length, the perpendicular length and the width from the highest in the age group of the 20s, 30s, 40s, and 50s.

Objective: This questionnaire study aimed to estimate the overall frequencies of positive perception towards orthodontic treatment among adults categorized according to age, sex, and area of living, and to identify barriers or negative perceptions preventing them from receiving orthodontic treatment. Methods: The participants included 598 adults aged over 20 years (230 men and 368 women) who visited the Dental Hospital of Seoul St. Mary's Hospital. The participants' opinions regarding their consideration of receiving orthodontic treatment were recorded using a specially designed questionnaire. Results: The overall rate of positive perception towards orthodontic treatment was 48.5%. Compared to adults in their 20s (63.2%), those in their 40s and 50s had a lower percentage of interest in orthodontic treatment (46.2% and 45.1%, respectively; p < 0.05). Overall, women (52.2%) had a higher rate of interest than did men (42.6%; p < 0.05). The area of living had no effect on the percentage of interest. The order of priority of chief complaints differed according to age: protrusion for those in the 20s and 30s, and spacing for those in the 40s to 60s. Overall, the main reason for not seeking treatment was the treatment fee. Respondents aged over 40 considered themselves "too old" for orthodontic treatment. Conclusions: The middle-aged had a relatively high percentage of interest (above 45%) in orthodontic treatment. However, demographic characteristics were not significantly associated with the positive interest. These results highlight the need for educating the middle-aged about the limitations and possibilities of orthodontic treatment to increase its acceptance.

Objectives: This study examined the practices of a community meal program for older adults in rural areas during the agricultural off-season. Methods: A survey was conducted from December 12 to December 22, 2016. Self-administered questionnaires were distributed to 150 cooking volunteers, who had participated in the community meal program in 50 villages. A total of 114 responses were returned from 44 villages and used for data analysis. In addition, in-depth interviews were conducted with the volunteers of eight villages. Results: Most of the cooking volunteers were 50 years old or older and they participated in serving older adults meals for good will. The cooking volunteers perceived that the older adults in their community did not eat various foods, had difficulties in grocery shopping, and frequently consumed salty foods. During the agricultural off-season, 40.9% of villages served the older adults meals 6-7 days a week and 95.5% provided meals for lunch. An average of 21 to 40 older adults were served meals in each village. The cooking volunteers reported that the food preparation and meal service times were sufficient, recipes provided were useful, and menus met the preference of the older adults. At the end of the program, they felt proud of serving meals for older adults in the community. An increased awareness of healthy eating, interest in health, and consumption of nutritious meals, a decrease in loneliness among older adults, and the promotion of fellowship in the community were rated highly. The cooking volunteers expected additional support for cooking personnel and insisted that the program should be provided for the entire agricultural off-seasons. Conclusions: The community meal program during the agricultural off-season for the elderly in rural areas was effective in improving the dietary life of older adults, relieving their feelings of isolation, and promoting fellowship of the community. The volunteers felt workload due to a shortage of volunteers but answered that they were rewarded by helping older adults in their community.

PURPOSE: The purpose of this study is to identify the incidence of chronic obstructive pulmonary disease (COPD) and risk factors for diseases in adults over 40 years of age in Korea, and to provide basic data for the prevention of COPD incidence through management. METHODS: Based on the 2019 data of the Korea National Health and Nutrition Examination Survey (KNHANES), 1,788 adults over the age of 40 who participated in pulmonary function test and health survey were selected as subjects. COPD incidence risk factors were analyzed using complex sample multiple logistic regression analysis. RESULTS: As a result of the analysis, the incidence of COPD in Korea was 11.5%, and the risk of developing COPD was higher in men, age, and current smokers. Compared to women, men had an increased risk of developing COPD by 2.369 times (95% CI 1.289-4.355). In age, the risk of COPD incidence increased by 3.702-fold (95% CI 1.923-7.124) in their 50s, 11.238-fold (95% CI 6.009-21.017) in their 60s, and 28.320-fold (95% CI 14.328-55.977) in their 70s compared to those in their 40s. In the smoking state, 2.302 times (95% CI 1.373-3.860) of past smokers and 4.542 times (95% CI 2.694-7.658) of current smokers were found to have a higher risk of developing COPD than non-smokers. CONCLUSION: To reduce the incidence of COPD, interventions are required to prevent disease development through lifestyle and smoking cessation education in subjects with COPD risk factors.

The purpose of this study is to find out how the adult's mental health in Korea has an impact on the quality of the life. By using '2010 National Health and Nutrition Examination Survey' data, 4,211 people among 20-year-old to 59-year-old adults were enrolled in this study. Frequency and percentage t-test using the SPSS WIN18.0 Multiple regression analysis was conducted and the results of this study are as follows. First, it is showed that in the 20s and 30s the females are a little more sleep than the males regarding the relationship between sleeping hours and the quality of the life of adult men and women. However, there are no differences between the 40s and 50s groups. Second, it is indicated that adult men are higher than women for the subjective health status when it comes to the subjective health status and the usual perceived stress. Although there are no statistical differences according to the gender in the 40s and the 50s, they have a little stress in general. Third, it is confirmed that only the subjective health status and usual stress perception give an beneficial influence on the quality of adult's life in the adult's mental health variations and the quality of life. In summary, this study was found that the adults in the 20s and 50s could increase their satisfaction of their life if they have more positive thinking and less stress from their life. Therefore, the systematical education and programs to manage the health and stress are required.

Purpose: The purpose of this study was to assess the diet intake status and quality of adults from North Korea who had lived in Seoul and Gyeonggi-do, using the nutrition quotient (NQ) for Korean adults. Methods: A number of 166 adults aged from 20 to 64 years were enrolled as study subjects. A structured questionnaire was used to collect information on their demographic characteristics, food consumption frequency, eating behaviors, and NQ. The NQ score was then used to measure the overall diet quality. The NQ score was composed of four major age-based categories. 'Balance', 'Diversity', 'Moderation', and 'Dietary behavior' were utilized as scores for measurements within each of the four categories. The scores for all four categories were summed up, resulting in the total NQ score. Participants' age groups were stratified by 20's, 30's, 40', and over 50's. A χ² test and generalized linear regression (GLM) model were used to assess a significance for difference of subject distribution in categorical and continuous variables in the food consumption frequency, eating behaviors, and NQ scores. Results: Participants in younger age groups were more likely to report consumption of ramyeon, fast food, sweet and greasy baked products, processed beverage, delivery food, and night snacks than the older age groups. Most importantly, participants in 20's age group were less likely to report the total NQ and moderation score than the 50's age group. Conclusion: In this study, the 20's age group displayed a lower NQ characteristic for an unbalanced diet. Therefore, it is imperative for adults from North Korea to be given individualized diet instructions along with nutritional education programs.

A cross-sectional analysis of blood pressure (BP) changes and the current prevalence and distribution of hypertension among age groups in Korea were conducted. Systolic (SBP), diastolic (DBP), and pulse (PP) pressures were evaluated. Residents visiting a local Community Health Center for a health check-up and/or participating in the Health Promotion Program were included for the analyses. A total of 6,570 subjects (2,809 men, 3,761 women) were divided into five age groups: 30-39, 40-49, 50-59, 60-69, and $70\leq$ years. Comparisons were made between sex and among age groups. SBP and DBP were continuously elevated, while men showed higher levels than women until their mid-60s; then, the trend was reversed. DBP in men became elevated from their 30s, reaching the highest in the 40s then slowly decreasing. DBP in women increased up to their 40s and 50s, then reached a plateau. PP increased rapidly from the 50s in both sexes. The major contributor of age-related BP elevation may be large artery stiffness in men, particularly from their 50s, while the blood pressure elevation of women may relate to diverse factors including large artery stiffness, stroke volume, and ventricular ejection rate. The rapid elevation of PP after the 50s in both men and women could represent a risk of cardiovascular or coronary mortality, particularly with increasing age. The current data showed a higher rate of hypertension in both sexes compared to previous reports. When those with both high-normal BP and hypertension are looked at in combination, BP management of the target population should be drastically elevated.
