The present study showed WHtR to be significantly better than BMI and WC for prediction of metabolic-related diseases in the middle-aged and older people in Korea, based on Bayesian ordered probit model analysis. The variations of WC, BMI and WHtR were compared according to the number of metabolic-related diseases such as hypertension, dyslipidemia, stroke, myocardial infarction, angina pectoris and diabetes. It was found that the three measures showed the similar variation except a very few extreme cases for age less than 40. For subjects over the age of 40, WC was not significant and WHtR gave more influence in greater variability than BMI on the number of metabolic diseases. Also, the rate of change for WHtR was higher than for BMI as the number of metabolic-related diseases increased. Specifically, the difference of the marginal effect of WHtR between no disease and only one disease was 1.81 times higher than that of BMI. Moreover, it was pointed out that the threshold value of WHtR for obesity should be considered differently by age.

Although excessive intake of sodium is known to cause various diseases and threaten public health and policies for reducing overconsumption of sodium are being implemented, the theoretical research on sodium intake is incomplete. This study attempted to provide a policy basis by examining whether or not planned behavior theory, which is a typical health communication theory used to describe health-related behaviors, can be applied to explain sodium intake behavior. Especially, sodium ingestion behaviors were compared using the theory of actions planned for men and women as well as young people, middle-aged, and elderly persons, who are predicted to show differences in eating habits. In this study, questionnaires were prepared to measure the daily eating habits of subjects and subordinate factors of planned behavior theory: behavioral beliefs, outcome expectations, normative beliefs, compliance motivation, and control beliefs. Questionnaires were given to 93 college students and their families. As a result of the difference analysis and path analysis of the questionnaire responses, the following suggestions were obtained. First, age difference is more obvious than sex difference in terms of low salt intentions. For example, older people are healthier than younger people in terms of eating habits and health concerns. Second, the elderly are more likely to practice the low-salt formula when they are provided information on the benefits and effects of the low-salt formula compared to younger ones. Third, systematic efforts are needed to promote a culture that emphasizes the health benefits of a low salt diet rather than providing piecemeal information on the advantages and effects of a low salt diet.

This study is to explore the housing problems and environment conditions perceived by residents in traditional houses in Suzhou, China. The empirical data is based on a questionnaire survey, which were from 100 residents in traditional area in Gusu area of Suzhou. In order to understand the traditional houses, on-the-spot investigation and literature review methods are adapted in this study. The main findings are as follows. Firstly, most of residents are middle-aged or older people, and their income is not high. Secondly, there are almost no cases of organizing independent workroom and storage room in their housing. Moreover, the main problems are mildew, theft, rats and cockroaches, etc. Finally, the satisfaction with the internal housing environment was appeared reasonable, but the external environment is unsatisfactory. Therefore, the external environment should be more considered in the Chinese traditional housing policy.

Objectives: This study was to investigate the relation of Pittsburgh Sleep Quality Index(PSQI) and Diagnos system of oriental medicine(DSOM) in the Insomnia Patients. Methods: For this study, we carried out PSQI and DSOM of 92 patients with insomnia who have come to Kijang public health center and Donguei oriental hospital of Donguei university from November 2008 to October 2009. We verified the association of PSQI and DSOM using crosstabulation analysis, independent sample T-test, one-way ANOVA and correlation analysis. Results: 1. Blood-deficiency(血虛) is the most frequent pathogenic factor and frequency of nightmare has positive correlation with that factor including heart(心) in total insomnia patients. 2. Female patients have a higher percentage of chronic insomnia than male patients. 3. As patients aged, maintaining sleep gets harder, sleep time is lessening, taking hypnotics is increasing and quality of sleep gets worse. 4. There is high frequency of chronic insomnia in 40~50 years and over 60 years old. Also, the people who are over 60 years of age tend to sleepless and urinated frequently during the middle of the night. The people with the age of 20~30 years tend to take less sleeping pills and frequency of sleeping during daytime is higher than the other age groups but the quality of sleep is quite good. 5. The patient with over 6 months of chronic insomnia tend to be older in age than the patient with less than 6 months. And the patient with chronic sleeping disorder has frequent pain and the quality of sleep is very poor. 6. The patient who took hypnotics tend to be older than hypnotics non-user and frequency of urination was relatively high. 7. The patient who visited oriental medical hospital were tend to be older and get difficult in maintaining sleep. And frequency of taking hypnotics and urinating during night were tend to be higher and the quality of sleep was poor compared with the patient who visited public health center. Conclusions: This study provides insights into the complicated relations of the associated symptom of insomnia with Diagnos system of oriental medicine. And especially this study showed apparent correlation between nightmare in insomnia patients and pathogenic factor of blood-deficiency and heart. Specific correlations and characteristics in this study could be connect develop of new questionaire of insomnia.

Early prevention of sarcopenia can be an important strategy for muscle maintenance, but most studies target subjects at slightly pre-sarcopenic state. Our previous paper describes the effect of protein supplements rich in leucine and vitamin D on muscle condition, and in this paper, we performed a sub-analysis to evaluate who benefitted the most in terms of improvement in muscle health. A 12-week randomized clinical trial of 120 healthy adults (aged 50 to 80) assigned to an intervention group (n = 60) or control group (n = 60) were analyzed. Subjects in the intervention group received, twice per day, a protein supplement containing (per serving) 800 IU of vitamin D, 20 g of protein (3 g of total leucine), 300 mg of calcium, 1.1 g of fat, and 2.5 g of carbohydrate. The subjects were classified into 'insufficient' and 'sufficient' groups at 25-hydroxyvitamin D (25[OH]D) value of 30 ng/mL. The skeletal muscle mass index normalized to the square of the skeletal muscle mass (SMM) height (kg/m²) increased significantly in the 'insufficient group' difference value of change between weeks 0 and 12 (Δ1.07 ± 2.20; p = 0.037). The SMM normalized by body weight (kg/kg, %) was higher, but not significantly, in the insufficient group (Δ0.38 ± 0.69; p = 0.050). For people with insufficient (serum 25[OH]D), supplemental intake of protein and vitamin D, calcium, and leucine and adequate energy intake increases muscle mass in middle-aged and older adults and would be likely to exert a beneficial effect on muscle health.

Purpose: The purpose of this study is to identify the effect of the disease duration on depression change in cancer survivors between the middle and old age groups. Methodology: To that end, we analyzed 275 patients using the Korea welfare panel survey from 2011 to 2016 jointly developed by the Korea Institute for Health and Social Affairs and Seoul National University. The duration of the elapsed and the experienced was measured as a independent variable. CES-D was used as a dependent variable. Frequency, paired t-test, ANOVA, and logistic regression analysis were conducted using Stata 14.0 for statistical analysis. Findings: Studies have shown that as the duration of the elapsed and the experienced increases, people under 65 are 1.17 times and 1.84 times each more likely to be included in depression-increase group than in depression-reduction group. The group that has been maintaining economic activities continuously since 2011 was significantly less likely to belong to the depression-increase group than the group that did not have economic activities in 2016. For those aged 65 and older, there was no significant difference in the duration of the elapsed and the experienced. The higher the likelihood of low-income households being included in the family of depression was 2.58 times higher than for ordinary households. Practical Implications: It is suggested that close policy management of the employment and working environment of cancer survivors is necessary, as both cancer survivors of productive age as well as older cancer survivors are analyzed to be beneficial to depression management. In addition, a systematic management program related to the mental health of cancer survivors is believed to be necessary for normal social recovery in the future.

The purpose of this study is to redefine 7 social exclusion factors and to derive association between social exclusion factors and depression of middle and older elderly, focused on gender differences. The elderly aged over 50 years old were extracted from the data of the Korean Longitudinal Study of Ageing (KLoSA) in 2016. The data was analyzed by descriptive analysis, chi-squared test, and binary logistic regression analysis, using SAS 9.4. As a result, the elderly who were excluded from labor, residence, health, and relationship were found to be associated to depression. In addition, male with resident exclusion were associated with depression compared to non-excluded. Therefore, it is necessary to improve the local community programs in which elderly people can participate in labor and cultural activity. It is necessary to improve labor and culture exclusion by increasing the participation opportunities of various cultural programs. In addition, it is needed to establish specific guidelines for eliminating the social exclusion of overall elderly.

For the development and better use of information and communication technology(ICT) for promoting health and quality of life in older people, it is important to understand personal factors associated with ICT use. The aims of this study were to describe the pattern of ICT use according to health characteristics of elderly and to investigate significant factors related to ICT use among three age groups. The data of 2017 National Survey of Older Koreans was used for analysis and 10,058 of older adults aged 65 and over were included for study participants. As results, first, the young old(65~74) used more functions of ICT than the middle-old(75~84) and the old-old(85 and over). Second, ICT was more used among older people with good conditions in chronic disease, subjective health, cognition, depression, vision, hearing, walking and IADL. Third, higher prevalence of ICT use was significantly associated with age, education, household income, subjective health, depression, cognitive function, vision limitation and walking limitation. Fourth, factors influencing the use of ICT were a little different among three age groups. For the young-old(65~74), subjective health, depression, cognitive decline, walking limitation, and IADL disability were significant factors affecting on ICT use. For the middle-old(75-84), subjective health, depression, cognitive decline, vision, hearing, and walking limitation were related with their ICT use. For the old-old(85 and over), only cognitive function and depression were associated with their ICT use. Based on these results, this study suggested the need to consider multiple health conditions for developing and using ICT for older adults.

Objective : This study was a covariance structural analysis to identify korean medicine health promotion behavior by the general characteristics of the subjects and build a predictive model and theoretical framework based on Pender's health promotion model(1996) and related literature reviews. Method : A hypothetical model was consisted of 8 theoretical variables and 27 measured variables. Related variables included Individual Characteristics and Experience, Behavior-specific cognitions and affect and Behavioral outcome. The data was collected from 802 middle and old-aged people living in Seoul and Gyeong gi province through structured questionnaires by face to face interviews between February and March, 2014. SAS ver. 9.1 and AMOS 18.0 programs were used for the data analysis. Results : Difference in the verification of Korean medicine health promotion behavior by the general characteristics, Older people who are male, with higher economic status, no chronic disease or with diabetes, no smoking, no drinking, with more exercise showed significantly higher scores, but education level has no difference. 15 paths were statistically significant among 16 paths on the direct effect, 6 paths were statistically significant among 9 paths on the indirect effect in the hypothetical model. The greatest impact variable on Korean medicine health promotion behavior was perceived self-esteem. Also, the findings showed that the higher perceived social support, perceived health status, previous Korean medicine health promotion behavior, community environment, perceived benefit and the lower perceived barrier had a significant effect on Korean medicine health promotion behavior. Conclusion : This research model has an empirical validity as the variables of this study verified their effects and significances. Therefore, the understanding of Korean medicine health promotion behavior can be increased and the utilization will be higher when seeking a comprehensive health promotion plan. Also, a strategy can be utilized the strategy for Korean medicine health promotion behavior.
