The trend towards ageing populations has been observed over many years in Europe and the US but has accelerated significantly in developed countries in Asia including Japan and South Korea. In the latter country the elderly population (65+) has increased 5-fold between 1960 and 2000 and this group will comprise 40% of the population by 2050. This creates a new socio-economic group with specific demands and considerable spending power. As ageing occurs a range of changes occur in the body that can be moderated by adjustments in nutrition. A significant body of evidence points to changes in the balance of glutathione synthesis and utilisation as people age. Glutathione is the most important natural anti-oxidant of the body and the amounts present can become limited by available cysteine in the diet. A cysteine-enriched peptide product, Cysteine Peption$^{TM}$ has been developed by DMV International for dietary supplement and food applications. A qualitative consumer trial has indicated benefits including improved sleep and more energy. Animal and clinical trials will be described that provide indications on bioavailability and possible mechanisms of action of Cysteine Peption$^{TM}$ with particular focus on the ageing population.

Background: The purpose of this study was to identify the status of Successful Aging among the elderly aged 65 and over in rural areas and to compare factors related with Successful Aging between "kyung-ro-dang" users and non-users. Methods: A total of 181 elderly aged 65 or older were selected from four districts (Heung-upri, Mejiri, Sajerri, and Daeanri) of Wonju city. A survey method using face to face interviews was applied to collect information. Successful aging was measured on a 5-point Likert-type scale using the successful aging scale developed for the Korean elderly, which indicates the higher the score, the higher the level of successful aging. Descriptive statistics, bivariate, and multivariate analyses were computed; the level of significance was set at 5%. Hierarchical polynomial regression was applied to find out the factors associated with successful aging. Results: Of the total, 112 elders used kyung-ro-dang and 69 elders who did not use kyung-ro-dang. The level of successful aging of the elderly was higher among kyung-ro-dang users than non-users. The factors related to successful aging among kyung-ro-dang users were walking and social participation. Users who walk more than 4 times per week and social participation activities have a higher level of satisfaction. In the case of non-users, a higher level of monthly income, having a spouse, social support, and social participation associated with a higher level of successful aging. Conclusion: Monthly income, social participation, and social factors were found to be related to successful aging along with physical and mental health conditions among the elderly in rural areas. Therefore, it can be concluded that income, social as well as mental and physical factors, are more critical for successful aging in the rural community care in Korea.

The purpose of this study was to investigate the effects of a 12-weeks aquarobics on metabolic syndrome risk factors and health fitness in 25 abdominally obese elderly women. As the results, while waist circumference(87.40/82.76cm, p<.01) decreased, HDL-C(41.13/45.42mg/dl, p<.05) increased after the exercise program. Blood pressure and TG, however, decreased with no significance. And while muscle strength increased(17.06/19.08kg, p<.05), the increase in flexibility, muscle endurance, and cardiopulmonary endurance and the decrease in body fat showed some positive effects of the exercise program. In conclusion, we found that the aquarobics improves the aging-induced deterioration in the muscular skeletal function by lowering abdominal obesity and improving metabolic syndrome and physical fitness for health. In addition, the aquarobics can be an effective alternative to an aerobics or a resistance exercise on the ground.

The purpose of the current study is to to examine the psychometric properties of the Subjective Agingwell Scale (SAS). Three hundred and forty two elders completed the SAS and the scales assessing subjective well-being, optimism, perceived control and adhering to healthy behavior. The 11-item SAS that displays good internal reliability and good fit to the three-factor model consisting of cognitive satisfaction, positive affect, and spiritual fullness. Correlational analyses with measures of subjective agingwell, subjective well-being, and optimism provide evidence for construct validity. Moreover, the results from hierarchical regression analyses show criterion-related validity of the SAS. This scale could be used in the field to measure and promote subjective agingwell.

Purpose: This study was conducted to evaluate the factors influencing inadequate energy intake among Korean elderly. Methods: Our study included 1,869 elderly people (over 60 years old) who completed a dietary survey from the fifth Korean NHANES (2010). Factors that could affect the nutritional status of the elderly included age, family status, socio-economic factors (education, family income, livelihood security, employment), and health related factors (having chronic disease, functional status, diet therapy, depression, and suicidal thoughts). Energy and protein intake were assessed using the dietary intake data from 24hr recall method. Results: The percentage of people who consumed energy less than 75% of EEA for Koreans was 23.7% in men, 31.1% in women. The carbohydrate contribution to the total energy intake in the inadequate energy intake group was significantly higher than that in the adequate intake group (p < 0.05). Factors significantly related to inadequate energy intake after adjusting for age, family status, education, family income, employment, functional status, and suicidal thoughts were education (OR: 1.480 in men, 1.614 in women) and employment (OR: 1.751 in men, 1.464 in women), age 70 years or older in men (OR: 1.475), and living with family but without spouse in women (OR: 1.496). Conclusion: In summary, the results imply that energy intake of elderly would be affected by the status of social environment with aging and nutrition-related policy for Korean elderly should be based on the social status as well as health related conditions.

Purpose: Although the importance of life satisfaction in patients with chronic diseases has been emphasized, limited studies have been performed on the health-related quality of life (HRQoL) among elderly patients with chronic diseases. This study examined the HRQoL among Korean patients with diabetes aged 65 years or older. Methods: This study used data from the Korea National Health and Nutrition Examination Survey 2008-2016. The analysis included data of 2,353 elderly patients with diabetes aged 65 years or older who were aware that they had type 2 diabetes. Each participant was categorized into one of three age groups (65-69 years, 70-74 years, and ≥ 75 years). The EuroQol-5 Dimensions (EQ-5D) scale was computed to estimate the HRQoL. Multivariate linear regression analysis was used to compare the demographic characteristics, lifestyle characteristics, nutrient intake, and EQ-5D scores between the age groups. Results: The intake levels of most nutrients were similar in the three age groups, but the total energy intake levels were significantly lower, and the sodium intake levels were significantly higher in the older age groups (p < 0.001). In addition, all items of the EQ-5D index, except for anxiety/depression, tended to decrease with age. In particular, the oldest age group (≥ 75 years) showed significantly lower levels on most items and the EQ-5D index than those in the other age groups (p < 0.001). Conclusion: Elderly patients with type 2 diabetes may have low levels of life satisfaction, which worsens with increasing age. Therefore, it is important to develop and manage personalized guidelines and medical systems so that elderly patients have a higher quality of life for the remainder of their lives. The results of this study are expected to be used as basic data for the systematic management of diabetes in elderly Korean patients.

Objective : This study aimed to identify types of leisure time spending of the Korean elderly according to the data of Hours of Living 2014 from National Statistical Office, and compare and analyze features of leisure time spending based on general characteristics of the elderly. Method : This study has only adopted the data of 9228 elder people whose ages were above 65, and their general characteristics and time spending features form the data of Hours of Living 2014. The final comparison and analysis has been made through behavior classification (1 major classification, 7 medium classification, 39 minor classification), which reflects how the elderly spend their leisure time according to their household and personal characteristics. Result : Firstly, the Korean elderly were found to spend most of their leisure time with media. Secondly, analyzing the features of leisure time spending based on household characteristics of the elderly, their gender and household income showed significant differences in all types of leisure time activities except for cultural and sightseeing activity. And their marital status showed significant differences in most of the leisure time activities excluding leisure time activity with media and cultural and sightseeing activity. Thirdly, analyzing the features of leisure time spending based on personal characteristics of the elderly, their education level has made significant differences in all types of leisure time activities. As for their economic activity status and average monthly income, they showed meaningful differences in most of the leisure time activities excluding cultural and sightseeing activity and ritual activity. Conclusion : We should help to find meaningful occupation within personal contexts and arrange it properly with balanced leisure time spending. Moreover, it is highly important to have appropriate occupational approach to prevent social isolation of the Korean elderly, and ensure their fruitful and successful later life.

The purpose of this study is to identify the characteristics and factors of each area by considering the gender health of the elderly as the integration of mental, physical, emotional, and social gender health based on the WHO gender health. The sexual health of the elderly is significantly different by gender, academic background, and region, and there is a clear difference in mental, physical, emotional sexual health and social sexual health. The mental, physical and emotional sexual health of the elderly in urban areas, those with high education and male is high, but the elderly in the rural areas, those with low education, and female are high in social sexual health. The factors affecting sexual health are as follows. Mental sexual health was positively influenced by satisfaction of sexual life and sexual knowledge. Physical sexual health was positively influenced by life and spouse satisfaction, and emotional sexual health was positively influenced by sexual relationship, spouse satisfaction, sexual life satisfaction and sexual knowledge. Social sexual health has a negative (-) effect on spouse satisfaction and sexual relationships. Integrated sexual health in old age can affect subjective health and quality of life, leading to successful aging. Sexual health education is needed to form a safe and healthy sexual life and interpersonal relationship. The 'sex' that appears as a cumulative trajectory of life should be accompanied by the accurate sexual health awareness and sex education that encompasses all generations. Therefore, in the composition of sex health education program, it is necessary to reflect the components that can enhance the sensitivity of adulthood to strengthen understanding and communication of spouse.
