Purpose: The purpose of this study is to measure health-related quality of life (HRQoL) and to investigate the affecting factors according to gender in older adults by using the 2012 Korea Health Panel data. Methods: The Korea Health Panel data 2012 were collected from February to August 2012 by Korea Institute for Health and Social Affairs and National Health Insurance Corporation and the number of respondents were 1,921. The data were analyzed by t-test, chi-square, Pearson correlation coefficient and multiple regression using SPSS/WIN program. Results: The limitation of activity was the most influential factor for health-related quality of life of both male and female. For male, the affecting factors on HRQoL were hearing problems and frustration. For female, the affecting factors on HRQoL were eating problems, depression and suicidal impulses. Drinking, moderate physical activities, vision problems and stress had a significant effect on HRQoL for both male and female. Conclusion: Health care providers should consider the differences between male and female when they design a program in order to improve HRQoL of older people.

The purpose of this study is to investigate types of neighborhood environments and to verify whether the types of neighborhood environments are directly related to life satisfaction of older adults. To achieve this goal, I used'2014 National Survey on Older Koreans' data which surveyed the older adults aged 65 and over living in the community and a total of 10,281 respondents were analyzed. To determine the types of neighborhood environment, the time taken by walking from community organizations or places such as grocery stores, medical centers, administrative agencies, welfare centers, public transportation was used as an neighborhood environment indicators. As a results, there were six types of neighborhood environment: a leisure-welfare walk-limited type(20.3%), a leisure-welfare long-distance type(15.5%), a balanced proximity type(7.8%), a store-traffic type(35.8%), a traffic proximity type(10.1%), and a marginalized area type(11.3%). Compared to the balanced proximity type, older adults living in a store-traffic type and a marginalized area type were more likely to have negative life satisfaction. older adults who have higher life satisfaction were more likely to be female, more educated, get higher household income, and have a spouses or partner. Moreover, the better the health conditions, the higher the frequency of contact with children, siblings, friends and neighbors, the higher the satisfaction of life. Finding from the study highlight the importance of neighborhood environment in late life and provide implications for building age-friendly community.

The purpose of this study was to investigate food intake, dietary diversity and dietary pattern during the summer in middle aged and older adults living in Gugoksundam (Gurye, Goksung, Sunchang and Damyang counties), Jeonla Province located in southern part of Korea and known as one of the representative Korean longevity areas. Food intake and dietary diversity were assessed by using the data from 2 day-24 hour recall of 1,051 subjects (394 males and 711 females) aged 45 years and older (45-93 years in male, 45-105 years in female). The average ages of males and females were 70.7 years and 71.1 years, respectively. Average total daily food intake was significantly decreased with aging in both genders, and the average animal food intake ratio to total food intake was ranged 10~14% in 3 different age groups, 45~64 years, 65~74 years and 75 years and older. The contribution of each food group, in weight, to total food intake showed the descending order of grains, fruits, vegetables and alcohols in males, and grains, fruits, potatoes and meats in females. On daily intake amount of each food item, rice, watermelon, soju, kimchi, and potato were ranked on top 5 in descending order in males, and rice, watermelon, potato, kimchi and ylmukimchi in females. On intake frequency, rice, kimchi, onion, green pepper and potato were ranked on top 5 in descending order in both genders. Dietary variety score (DVS) and dietary diversity score (DDS) for the assessment of dietary diversity and balance were significantly decreased with aging in both genders. In food group intake pattern (DMGFV), 01101 type without consumption of dairy and fruits was the most prevalent, and only 3.6% of male and 3.9% of female subjects showed 11111 type, consumed all the 5 food groups a day. Dietary pattern of subjects was analyzed by cluster analysis with 18 food groups intake. Overall dietary pattern was classified into two clusters, one was more desirable and the other was less desirable. The percentage of subjects with more desirable dietary pattern was about 15% in male and 32% in female. In conclusion, most of our subjects living in Gugoksundam area were taking very simple diet with low amount of dairy products and fruits. These results indicate that nutrition intervention and education for older people living in rural areas should be focused on various food intake including dairy products and fruits.

In this study, obese adults were compared for their ability to predict obesity and lipid related variables and their optimal cutoff values to predict metabolic syndrome and insulin resistance. In this study, 9,256 adults aged 20 years or older and less than 80 years old, who were in the Gyeonggi region from January 2014 to December 2016 and who were examined at a general hospital, were enrolled. The diagnostic criteria for obesity were WHO (World Health Organization), and BMI $25kg/m^2$ or more presented in the Asia-Pacific region. Metabolic syndrome was diagnosed based on the criteria of American Heart Association / National Heart, Lung, and Blood Institute (AHA / NHLBI). According to the results of receiver operating characteristic curve (ROC) analysis, Triglyceride / HDL-cholesterol (TG / HDL-C), Triglyceride and Glucose (TyG) index, lipid accumulation product (LAP) and visceral adiposity index (VAI) showed high predictive power for diagnosing metabolic syndrome. The diagnostic accuracy of LAP (AUC: 0.854) for males and VAI (0.888) for females was the highest. The optimal cutoff value of LAP was 42.71 for male and 35.44 for female, and the cutoff value of VAI was 1.92 for male and 2.15 for female. In addition, WHtR (waist to height ratio), TyG index, and LAP were used as predictors of insulin resistance in obese adults. Therefore, LAP and VAI were superior to other indicators in predicting metabolic syndrome in obese adults.

The purpose of this study was to verify whether there are any differences in the level of exercise self-efficacy and perceived health status according to the stage of change for exercise behaviors in older adults. The subjects consisted of 231 older adults (91 male, 140 female) by convenience sampling residing in city D. The collected dates were analyzed using one-way ANOVA, Tukey HSD, and simple regression analysis by SPSS WIN 21.0 program. Moreover, all statistical significance level was set at a=.05. The study results were as follows: Analysis of variance showed that exercise self-efficacy showed significant differences according to the stage of change for exercise behaviors, and as a result of the posthoc analysis, it was found that as the stage became higher, their exercise self-efficacy became higher as well. Perceived health status showed significant differences according to the stage of change for exercise behaviors, and as a result of the posthoc analysis, it was found that as the stage became higher, their perceived health status became higher as well. Analysis of variance showed that exercise self-efficacy and perceived health status were significantly associated with the stages of exercise behavior change. This study identified that exercise self-efficacy and perceived health status were significant variables to explain a possible relationship with exercise stages of older adults. This study provides new information to influence the development of the better health promotion and exercise intervention for older adults in the community.

This study, to confirm the mediating effect of knee pain on cognitive functions and depression in older adults, and as an interdisciplinary research between the physical and psychological mechanisms, confirmed the identifying group differences by gender, age, and educational attainment of older adults, and aimed to research the improvement of cognitive functions, which is a main factor of dementia's risk prediction. The analysis data was from the 8th Korean Longitudinal Study of Ageing (KLoSA) in 2020, and the research model was verified using Process macro and model #4. The main analysis results are as follows. First, depression partially mediation effect of knee pain on cognitive functions. Second, the mediation effect of depression by gender was significant, but the direct effect in the male older adults group was twice that in the female older adults; the indirect effect did not vary significantly based on gender. Third, the mediating effect of depression by age was relatively greater in the old-old aged group than in the young-old aged one. Fourth, as for the mediating effect of depression according to the classification of educational attainment, the mediating effect was not significant in the group with a college degree or higher education but was significant in the remaining three sub-groups. Based on the results, this study makes implications for the need for active intervention strategies to improve cognitive functions, focusing on group differences by gender, age, and educational attainment in the management of knee pain and depression.

This study was done to analyze the consumption patterns of health functional food (HFF) as well as to perform needs assessment for the development of web-contents on HFF according to age of adults. The subjects were 238 male and female adults, divided into 4 groups by their age. This study collected all information by self-administrated questionnaires. The awareness on HFF was high in the older adults. The younger adults showed more negative responses to reliability and safety on HFF. The main reason for the consumption of HFF was to supplement nutrients and to prevent diseases. The main types of HFF consumed by adults were nutritional supplementary food, red ginseng products, and glucosamine products. There was higher consumption of nutritional supplementary food in the younger adults and glucosamine products in the older adults. Internet users had low level of satisfaction, with tendency to complain poor contents, reliability, difficulties in searching as problems of the pre-existing HFF websites. As useful methods for provision of information on HFF, most adults wanted general information, articles written by experts and videos. They also wanted to know the safety and side effects of HFF. Requirement of contents composition were various in-depth information, clear indication of citation, fresh updated data while that of display composition was easily-findable, uncomplicated, allowing mutual exchange of communication through bulletin board. These results can be used as basic data that reflect the consumer's needs for developing HFF web-contents according to age of adults.

This study examines gender differentials in depression among Korean older adults. Using logistic regression and decomposition methods, this study analyzes factors that predict depression of a full sample and separate male/female samples, respectively. Further, this study decomposes factors that affect gender differentials in depression into two components: the distributions of individual variables and the returns to risk. This study finds the variables that separately predict depression by gender. For male, having a smaller social network is associated with depression; however for female, the number of falls is associated with depression. This study also finds that being married, having greater satisfaction with current financial situation, and having good physical health increases the gap between males' and females'depression. Married male have greater returns from marriage than females. If females had the same returns as male, then the gap would have decreased by about 40%.

Purpose: The purpose of this study was to categorize and to understand the structure of subjectivity in the gender role identity of older female adults. The perception of gender role identity is subjective and varies according to the uniqueness of individual experiences and the value of social culture. Methods: Q-methodology, a technique for extracting subjective opinions was used. In 2010, forty participants completed the Q-sort activity, rating each statement relative to the others. The Q sample has two categories, representing masculinity and femininity, and each category has 20 statements, resulting in 40 adjectives. Results: Using the Q factor analysis, three classifications were identified: 'caring-affectionate type,', 'assertive-confident type,' and 'sensitive-affectionate type.' Despite the differences among the three types in this research, elderly females are likely to have the understanding and patience to comfort others and care for the children. Conclusion: The results of this study revealed new dimensional types of gender role identity and raise the issue of why we need to develop methods for the new dimensional types. Based on the results, further research is needed to compare the findings with those of older males or with women of different age groups.

This study aims to identify predictors of driving cessation among Korean elderly. Data from 2011 Elderly Survey conducted by Ministry of Health and Welfare and Korea Institute for Health and Social Affairs were used for the analysis. Based on Webber, Porter, Menec(2010)'s comprehensive theoretical framework for mobility, the model of this study tests five major determinants of driving cessation including financial, psychosocial, environmental, physical and cognitive factors. Results of logistic regression analysis showed that economic status, marital status, contacts with relatives and friends, residential location, taking medication, muscle strength, age, gender, and job were significant predictors of driving cessation of older drivers. Specifically, lower economic status, unmarried status, less contacts with relatives and friends, living in the city, taking medication, weaker muscle strength, older age, female, non-working status were significant risk factors for driving cessation. Practical implications in light of study findings were discussed.
