This study aims to verify the mediating effect of social support in the relationship between online social relations service utilization(PC, mobile) and life satisfaction for middle-aged and Older Adults. For this purpose, the '2017 Digital Devide Survey' data collected by the National Information Society Agency was used, and among 2,300 middle-aged and Older Adults aged 55 or older, 1,488 people using the Internet were selected as the final analysis target. Then, using the structural equation, the mediating effect of social support was verified in the between online social relations service utilization and life satisfaction. As a result, it was verified that higher levels of mobile-based social relations service utilization have a positive effect on social support and life satisfaction. Also, it was confirmed that social support has a mediating effect in the relationship between the utilization of mobile-based social relations service and life satisfaction. However, the utilization of PC-based social relations services did not show to affect social support and life satisfaction. Therefore, the results of this study can be used as basic data for practical measures to increase the connection between mobile-based social relationship service education and social support promotion education for middle-aged and Older Adults. In addition, the study is meaningful in that it overcomes the limitations of measuring the use of online social relations services as one, and selects tools that are practically effective by dividing them into mobile and PC.

BACKGROUND/OBJECTIVES: This study investigated the association between dietary quality based on the Korean Healthy Eating Index (KHEI), and the prevalence of chronic conditions among middle-aged individuals (40-60 yrs of age) living alone. MATERIALS/METHODS: The participants were selected (1,517 men and 2,596 women) from the Korea National Health and Nutrition Examination Survey (KNHANES) 2016-2018 and classified into single-person households (SPH) and multi-person households (MPH). Nutrient intake, KHEI, and the prevalence of chronic conditions were compared according to household size. The odds ratios (ORs) of chronic conditions were analyzed according to the tertile levels of KHEI by gender within each household size category. RESULTS: Men in SPH had a significantly lower total KHEI score (P < 0.0001) and a lower prevalence of obesity (OR, 0.576) than those in MPH. For men, the adjusted ORs for obesity, hypertension, and hypertriglyceridemia in the first tertile (T1) of KHEI scores within SPH compared with the third tertile (T3) were 4.625, 3.790, and 4.333, respectively. Moreover, the adjusted OR for hypertriglyceridemia in the T1 group compared to the T3 group within the MPH was 1.556. For women, the adjusted ORs for obesity and hypertriglyceridemia in T1 compared to T3 within the SPH were 3.223 and 7.134, respectively, and 1.573 and 1.373 for obesity and hypertension, respectively, within MPH. CONCLUSIONS: A healthy eating index was associated with a reduced risk of chronic conditions in middle-aged adults. Greater adherence to a healthy eating index could lower the risk of chronic conditions in middle-aged adults living alone.

Objectives: We developed an integrated cognitive function improvement program comprising cognitive, emotional, and physical domains, and remotely applied it to middle-aged adults to investigate its effects on oral health, cognitive function, and mental health improvement. Methods: The experimental group underwent the program remotely, using the Zoom platform. A total of 24 participants were recruited and divided into 12 experimental and 12 control groups. The program comprised cognitive, emotional, and physical activities. The sessions lasted 90 min and were performed twice a week for 6 weeks from April to May 2022. Results: Cognitive function, arousal, physical, and mental stress were significantly improved in the experimental group after the intervention than at the baseline (p<0.05). Regarding oral health, tongue plaque decreased 1.34-fold (p<0.01) and saliva increased 1.04-fold (p<0.05) in the experimental group after the intervention than at the baseline. Moreover, the experimental group showed significant improvements in tongue plaque and saliva than the control group (p<0.05 for tongue plaque and p<0.01 for saliva). Regarding mental health, social support significantly increased 11.67-fold (p<0.05) in the experimental group than at the baseline. The experimental group also showed significantly improved social support than the control group (p<0.01). Conclusions: The non-face-to-face integrated cognitive function improvement program for middle-aged adults improved their cognitive function and oral and mental health. Based on these findings, this program may be a useful health program tool for middle-aged individuals.

Purpose This study aims to verify the mediating effect of the utilization performance of digital device on the relationship between user attitude and life satisfaction. Design/methodology/approach Using the data of 2018 Digital Divide Survey conducted by the National Information Society Agency(NIA), the mediating effect was verified by Baron & Kenny (1986)'s 3 step process, targeting 1,662 adults older than 55. Findings The result is as follows: first, the user attitude of middle and older aged people has a positive effect on their life satisfaction. Second, the effect of user Attitude towards Digital Device of middle and older citizens is partially mediated by the utilization performance of digital device. The results of this study indicate that when providing informatization education in the local community to promote the use of digital devices for the elderly, efforts should be made to grasp the level and inclination of informatization individually, and furthermore present improvements for wireless devices that the elderly can easily access in their daily lives. This study is expected to be a groundwork for a practical intervention to boost positive attitude towards using digital device to enhance the utilization performance of digital device and the life satisfaction of middle and older aged people.

The purpose of this study is to examine whether non-self perspective(NSP) reduces the negative effects of life stress experienced by middle-aged adults. an online survey was conducted using a sample of 207 adult men and women in their 40s and 50s, and a hierarchical regression analysis and simple slope analysis were performed. As a result, it was found that NSP modulates the negative effects of life stress on perceived stress and subjective well-being. Specifically, NSP reduced the positive effect of life event stress on perceived stress and reduced the negative effect on subjective well-being. The results of this study suggest that eastern and Buddhist self-view, NSP, has a buffering effect on life stress experienced by middle-aged adults. This study suggests that NSP should be considered as an important factor for coping with stress in middle-aged adults in counseling and clinical settings, and is expected to promote subsequent empirical research on the Buddhist concept of non-self. Finally, limitations and future studies are suggested.

Purpose: The purpose of this study was to examine a combined influence of obesity and metabolic syndrome on ischemic heart disease in Korean middle aged and older adults. Methods: This study used secondary data from the 2013 Korea National Health and Nutrition Examination Survey. A total of 3,726 adults over age 40 were included. Logistic regression was used for analysis of complex samples. Gender, age, educational level, family income, family history of ischemic heart disease, physical activity, smoking, and heavy alcohol consumption were analyzed as covariates. Results: Ischemic heart disease was more prevalent among adults with metabolic syndrome regardless of obesity (non-obesity: Adjusted Odds Ratio [AOR]: 3.044, 95% Confidence Interval [CI]: 1.163-7.967, overweight: AOR: 2.805, 95% CI: 1.246-6.316, obese: AOR: 3.137, 95% CI: 1.548-6.358) compared to the reference group, defined as adults with non-obesity and non-metabolic syndrome. Odds of ischemic heart disease were not significant in the group with obesity and non-metabolic syndrome compared to the reference group. Conclusion: The results of this study show that the population with metabolic syndrome is an at-risk group for ischemic heart disease. Thus, management of metabolic syndrome is required for prevention of ischemic heart disease.

Objectives: This study aimed to investigate factors influencing suicidal ideation among Korean adults. Methods: Cross-sectional data from the fifth Korea National Health and Nutritional Examination Survey conducted in 2012 were analyzed in this study. The subjects were categorized into three groups by subjects' age(defined as young adults(20-39), middle-aged adults(40-59), and the elderly(60 or more). Data were analyzed by frequency, Chi-square test and multiple logistic regression using SPSS 18.0. Results: The factors influencing suicidal ideation were different among three age groups. The influencing factors were (1) gender, marital status, household income, perceived stress and depression in the young adult group, (2) household income, perceived health status, perceived stress and depression in the middle-aged group, (3) gender, regular physical activity, smoking, perceived health status, perceived stress and depression in the elderly group. Conclusions: The health education considering the characteristics of each age group should be developed and applied to prevent adults' suicidal ideation because the factors influencing suicidal ideation were revealed differently between the age groups.

BACKGROUND/OBJECTIVES: We investigated the associations between eating away from home (EAFH) and overweight and obesity among Ugandan adults using the 2014 Uganda non-communicable disease risk factor survey. SUBJECTS/METHODS: In total, 3,025 participants aged 18-69 years were included in the analysis. The frequency of EAFH was assessed by asking participants the number of meals eaten per week that were not prepared at a home. EAFH frequency was categorized as; less than once/week, 1-2 times/week, or ≥ 3 times/week. Logistic regression was used to evaluate the associations between overweight, obesity, and EAFH. We also tested whether sex and age modified these associations. RESULTS: Participants that ate away from home ≥ 3 times/week were 2.13 times more likely to be obese than those that ate away from home less than once/week (odds ratio [OR], 2.13; 95% confidence interval [CI], 1.28-3.54). However, when the analysis was stratified by sex, women that ate away from home ≥ 3 times/week were 42% less likely to be overweight than those that ate away from home less than once/week (OR, 0.58; 95% CI, 0.36-0.94). Men that ate away from home ≥ 3 times a week were 3.89 times and 2.23 times more likely to be obese and overweight, respectively, than those that ate away from home less than once/week (obesity: OR, 3.89; 95% CI, 1.50-10.09; overweight: OR, 2.23; 95% CI, 1.42-3.51). Age-stratified analysis showed that among participants aged 31-50 years, those that ate away from home ≥ 3 times a week were 3.53 times more likely to be obese than those that ate away from home less than once/week (OR, 3.53; 95% CI, 1.69-7.37). CONCLUSIONS: Frequent EAFH was positively associated with overweight and obesity among men, and obesity among young/middle-aged adults, but negatively associated with overweight in women. Nutritional interventions for obesity reduction in Uganda should include strategies aimed at reducing the frequency of eating meals prepared away from home, and specifically target men and young/middle-aged adults.

The present research is aimed at to examine the relationships between wisdom and age, also between wisdom and its psychological adaptation among middle and elder adults in Korea. Moreover, using data on 240 middle-aged and elder adults, the relationship between different aspects of wisdom and aging well were not only examined, but also explored age differences of wisdom through adulthood. The major findings from the study are summarized as follows. first, the wisdom scores of middle-aged and elder adults were significantly higher than those of young adults. While 'cognitive competency' and 'positive life attitude' factors had no significant differences. It means that 'cognitive competency' and 'positive life attitude' wisdom could be stable across adulthood. However, 'moderation and balance' and 'sympathetic interpersonal relationship' wisdom of elders were significantly higher than those of young adults. second, in middle and elder adults, Wisdom was found to be positively related with life satisfaction, well-being, death acceptance, experiences of positive emotion, generativity, ego integration, and positive life review. while on the other hand, contrast wisdom to be negatively related with depression, fear of death, perceived stress and experiences of negative emotion. The results from the study were examined by ecological validity of wisdom. Accordingly, a number of limitations and implications of the research were acknowledged.
