Objectives: This study is to investigate the prevalence and related factors of metabolic syndrome among Korean adults aged 20 years and above. Methods: From the database of the $5^{th}$ Korea National Health and Nutrition Examination Survey (KNHANES V) conducted in 2010, data of 5,670 adults who responded to all the questionnaires of health interview and had metabolic syndrome in the health examination were included in this analysis. SAS 9.2 was used for statistical analysis with complex sample survey modules and commands. Results: The prevalence rate of metabolic syndrome based on the criteria proposed by International Diabetes Federation (IDF) was 18.8%. The prevalence of metabolic syndrome in each group was: 20.7% of women, 43.1% among elderly over 70 years old, 40.6% of the divorced or the separated, 27.6% of recipients of economic support from the government, 23.6% of people who had alcohol dependency problem, and 43.7% of overweight or obese adults. Independent risk factors based on the multiple logistic regression analysis revealed that prevalence of metabolic syndrome was associated with female (odds ratio 1.59 [95% confidence interval 1.20-2.11]), age (50s 3.95 [2.11-7.37], 60s 5.62 [2.98-10.61], 70s 10.56 [5.25-21.25]), high school education (0.52 [0.37-0.74]), clerk occupation (2.14 [1.27-3.60]), divorced marital status (1.72 [1.15-2.59]), alcohol dependency (1.86 [1.16-2.98]), higher BMI (14.08 [10.60-18.70]). Conclusions: The metabolic syndrome is prevalent among Korean adult population according to IDF criteria. Several demographic characteristics and potentially modifiable factors are associated with metabolic syndrome. Identification of this high-risk group and management of these modifiable factors are warranted to reduce the prevalence of metabolic syndrome.

Objectives: When elderly patients show depressive symptoms, discrimination between depressive disorder and prodromal phase of Alzheimer's disease is important. We tested whether a quantitative electroencephalogram (qEEG) marker was associated with cerebral amyloid-β (Aβ) deposition in older adults with depression. Methods: Non-demented older individuals (≥ 55years) diagnosed with depression were included in the analyses (n = 63; 76.2% female; mean age ± standard deviation 73.7 ± 6.87 years). The participants were divided into Aβ+ (n = 32) and Aβ- (n = 31) groups based on amyloid PET assessment. EEG was recorded during the 7min eye-closed (EC) phase and 3min eye-open (EO) phase, and all EEG data were analyzed using Fourier transform spectral analysis. We tested interaction effects among Aβ positivity, condition (EC vs. EO), laterality (left, midline, or right), and polarity (frontal, central, or posterior) for EEG alpha band power. Then, the EC-to-EO alpha reactivity index (ARI) was examined as a neurophysiological marker for predicting Aβ+ in depressed older adults. Results: The mean power spectral density of the alpha band in EO phase showed a significant difference between the Aβ+ and Aβ- groups (F = 6.258, p = 0.015). A significant 3-way interaction was observed among Aβ positivity, condition, and laterality on alpha-band power after adjusting for age, sex, educational years, global cognitive function, medication use, and white matter hyperintensities on MRI (F = 3.720, p = 0.030). However, post-hoc analyses showed no significant difference in ARI according to Aβ status in any regions of interest. Conclusion: Among older adults with depression, increased power in EO phase alpha band was associated with Aβ positivity. However, EC-to-EO ARI was not confirmed as a predictor for Aβ+ in depressed older individuals. Future studies with larger samples are needed to confirm our results.

This study aims to examine the effects of health status on life satisfaction and depression and to examine the effect of spirituality and religious involvement on this relationship among Korean older persons. On the basis of the previous literature, we hypothesize that health status will have a direct effect on life satisfaction and depression, but that spirituality and religious involvement will moderate this effect in addition to having direct effects on life satisfaction and depression. In light of the different gender effects on all five variables (health status, spirituality, religious involvement, life satisfaction, and depression), we also examine the effects of gender on these variables. The data for this study came from the Hallym Aging Study conducted by the Hallym University Institute of Aging from February to March in 2005. Through stratified multi-stage random sampling, 1409 individuals aged 65 and over, who lived in Seoul and Chuncheon in Korea. Multiple regression analysis was used to investigate whether health status, gender, spirituality and religious involvement could predict life satisfaction and depression, and whether the direct relationships were moderated by interactions among these variables. We took three ordered regression steps to examine the hypothesis; the first step contained the covariates of age, education, living with spouse, monthly expense, living with adult children, and household income. We also entered gender into this step, so it would be adjusted for in relation to the other covariates. The second step then looked for any direct effects that gender, health status, spirituality, and religious involvement might have on life satisfaction and depression above and beyond the effects of the covariates. The third step contained interaction terms to look for further variance accounted for by indirect, moderating effects on life satisfaction and depression. The results showed that health status had a significant effect on both life satisfaction and depression, and religious involvement had a significant effect on depression. Spirituality and religious involvement were found overall to be a moderator, reducing the negative effect of health status on life satisfaction and depression. The direct effect of religious involvement and the moderating effects of spirituality and religious involvement on life satisfaction and depression are consistent with the view that spirituality and religion are resources and benefit the well-being of older adults.

BACKGROUND/OBJECTIVES: The inverse relationships of combined fruits and vegetables intake with blood pressure have been reported. However, whether there are such relationships with salty vegetables has rarely been investigated in epidemiologic studies. We evaluated the relation of combined and separate intake of fruits, vegetable intakes, and salty vegetables, as well as sodium and potassium, with blood pressure among the middle-aged and elderly populations. SUBJECTS/METHODS: The present cross-sectional analysis of a prospective cohort baseline survey was performed with 6,283 subjects (2,443 men and 3,840 women) and free of hypertension, diabetes, cardiovascular diseases, and cancer. Dietary data were collected by trained interviewers using food frequency questionnaire. RESULTS: The significantly inverse linear trend of diastolic blood pressure (DBP) was found in fruits and non-pickled vegetables (81.2 mmHg in the lowest quintile vs 79.0 mmHg in the highest quintile, P for trend = 0.0040) and fruits only (80.9 mmHg in the lowest quintile vs 79.4 mmHg in the highest quintile, P for trend = 0.0430) among men. In contrast, sodium and sodium to potassium ratio were positively related with blood pressure among men (DBP, 78.8 mmHg in the lowest quintile vs 80.6 mmHg in the highest quintile, P for trend = 0.0079 for sodium; DBP, 79.0 mmHg in the lowest quintile vs 80.7 mmHg in the highest quintile, P for trend = 0.0199 and SBP, 123.8 mmHg in the lowest quintile vs 125.9 mmHg in the highest quintile for sodium/potassium). Kimchies consumption was positively related to DBP for men (78.2 mmHg in the lowest quintile vs 80.9 mmHg in the highest quintile for DBP, P for trend = 0.0003). Among women, these relations were not found. CONCLUSION: Fruits and/or non-pickled vegetables may be inversely, but sodium, sodium to potassium, and Kimchies may be positively related to blood pressure among men.

Consumer's perceptions of the qualities of food and food-related services were surveyed through questionnaires by 672 adults randomly selected from 20 industrial foodservice in Pusan and Kyeung Nam area. The results are as follows: 1) By age, the elderly group gaved the highest mean score not only for freshness and temperature among the food characteristics but also for cleanliness of dishes and materials of dishes among the food-related service. 2) By occupation, the white collar worker group gaved the highest mean score in all characteristics of food and food-related service than did the blue collar worker group. Especially for courtesy of employees, the mean rating given by the white collar worker group was 3.15/5.00, but by the blue collar worker group was 2.67/5.00. 3) Good appetitive group rated taste of food 3.15/5.00, quality of food vs. food price 3.17/5.00, and freshness 3.15/5.00. But poor appetitive group rated taste of food 2.44/5.00, quality of food vs. food price 2.65/5.00, and freshness 2.70/5.00. 4) Men agreed that the rice and soup were right in amount. And women responded that the rice was in a large amount and the soup was not enough. 5) The white collar worker group agreed that the rice, the soup, the side dish, and the kimchi were right in amount. However the blue collar worker group agreed that the rice was right in amount, the soup and the side dish were not enough, and the kimchi was in a large amount. For seasoning of food, the white collar worker group responded that the salty taste and the hotness were just right. But the blue collar worker group responded that the food was neither salty nor hot at all. 6) The taste of food was shown to be positively correlated (p<0.001) with various food item combinations, freshness of food, and the variety of cooking methods.

Zinc is an antioxidant trace mineral, scavenging free radicals and known to be involved in inflammatory reactions. The prevalence of atherogenic diseases such as coronary heart disease (CHD) are increasing in Korean adults of middle age and elderly. The increased cell damage from free radicals and inflammation have been implicated in etiology of CHD, and the evidence is accumulating that low zinc status is involved in the prevalence of this inflammatory atherogenic disease. However, little is known about the zinc status of Korean CHD and its relationship with dietary zinc intake and zinc bioavailabilty. In this study the serum zinc levels of male patients with CHD over 40 yrs. were compared with that of healthy adult males and its associations with dietary zinc intake and zinc bioavailabilty affecting factors were examined. Serum zinc level was measured by HANARO research reactor using neutron activation analysis (NAA) method. The overall proportion of patients with zinc deficiency, serum zinc concentrations below $74.0{\mu}g/dL$ was 32.8% compared to the 10.3% in healthy group. The average serum zinc levels were $80.7{\mu}g/dL\;and\;88.3{\mu}g/dL$ in patients and healthy group, respectively, showing significantly low zinc status in CHD patients compared to healthy group. The intake of nutrients such as energy, carbohydrate, iron, and copper of CHD patients was significantly higher compared to that of the healthy group. In addition, the intake of calcium, iron, and protein from vegetable foods was significantly higher in CHD patients than that of healthy group. The dietary zinc intake was $12.7{\pm}4.5mg$ and $11.5{\pm}6.9mg$ in CHD patients and control group, respectively, which showed no difference. The phytate intake of patients group, which is 1389.0 mg, was significantly higher than the control group which showed 1104.8 mg. However, the ratio of phytate: zinc or phytate * calcium. zinc per 1000 kcal energy intake did not show any difference between two groups. The serum zinc levels did not show any correlation with zinc or factors that affect the bioavailability of zinc. The dietary factors influencing the zinc status were not found in CHD patients.

Purpose : The objective of this study was to determine the major factors influencing the onset of diabetes and prediabetes and for collection of the basic data required to reduce the prevalence of diabetes and plan for administration of an effective health care system. By classifying the level of blood sugar management according to three categories: normal, prediabetes, and diabetes diagnosis, and determining the causes of diabetes in consideration of various variables, we will conduct an analysis of the main factors to be addressed for effective management of blood sugar and for preparation of basic data for use in early management. Methods : In this study, an analysis of raw data from the 8th National Health and Nutrition Examination Survey collected over a period of three years from 2019 to 2021, including 8,110 subjects in 2019, 7,359 subjects in 2020, and 7,090 subjects in 2021 was performed. A total of 22,559 subjects were aged 19 years or older, and 15,821 subjects were classified as subjects for inclusion in the final analysis. In the analysis, categorical variables were tested for difference, analysis of continuous variables using regression was performed, and analysis of influencing factors was performed using multinomial logistic analysis. Result : Significant factors related to the onset of diabetes and prediabetes included age (p<.001), marital status (p<.001), occupation (p<.001), hypertension (p<.001), dyslipidemia (p<.001), cardiovascular disease (p=.008), alcohol (p=.030) smoking (p=.005), systolic blood pressure (p<.001), diastolic blood pressure (p<.001), body mass index (p<.001) and waist circumference (p=.037), blood triglycerides (p<.001), and blood cholesterol (p<.001). Conclusion : Diabetes, a complex disease affected by a variety of diseases, requires active management from the prediabetes stage, and providing an appropriate level of medical information and services to elderly individuals without family support is considered a long-term health care system requirement in Korean society where the demographic structure is changing. In particular, determining the causes of prediabetes and development of a preventive approach to administering the health care system will be important for efficient management of diabetic patients.

This study was designed to evaluate the effects of arthritis and comorbid chronic conditions on the health-related quality of life (HRQoL) in the Korean older population. The study subjects were 2,708 Korean adults aged 65 and older from the $3^{rd}$ Korea National Health and Nutrition Examination Surveys data: 1,357 persons with a single chronic condition, such as arthritis, herniations of the intervertebral disc, osteoporosis, asthma, peptic ulcers, stroke, or cataract; 886 persons with arthritis and a second chronic condition described above; and 465 persons with no chronic condition. An analysis of covariance was performed to compare the EQ-5D index among the groups. The effects of arthritis, second chronic condition and their interactions were analyzed by multiple linear regression analysis. The results are as follows. Compared to men with arthritis only, men with stroke only, stroke and arthritis, or cataract and arthritis had a lower age adjusted EQ-5D index. Women with a stroke only, asthma only, cataract only, osteoporosis and arthritis, peptic ulcer and arthritis, stroke and arthritis, or cataract and arthritis had a lower age adjusted EQ-5D index than women with arthritis only. Arthritis and comorbid conditions had additive effects on the HRQol in both genders except for arthritis and stroke in women. In conclusion, comorbid chronic medical conditions in older people with arthritis may reduce the HRQoL in an additive manner.

Human metapneumovirus (hMPV) is a recently recognized human respiratory pathogen, which is known to be associated with upper and lower respiratory tract infections mainly in children, immunocompromised patients, and the elderly. The clinical manifestations of hMPV infections are similar to those of the human respiratory syncytial virus infection, which range from mild upper respiratory tract infection to severe bronchiolitis and pneumonia. Recently, hMPV has come to be thought of as the cause a similar spectrum of disease in adults as that seen in children; however, most of the reports of hMPV infections have focused on infection in children. We report a case of severe hMPV pneumonia requiring mechanical ventilation in an immunocompetent adult in Korea.

The purpose of this study was to perform a content analysis on 62 domestic and international journals from 1998 to 2017, in order to review research trends in music and people with visual impairments. The framework of the content analysis was based on the year of publication, field of journal, research method, type of research, research subject, participants' age, and factors of impairment. The results showed that both domestic and international journals have rapidly increased in the last 10 years, and have expanded into the fields of education and therapy. In the research method, survey research was conducted much more frequently in domestic journals, while both qualitative and experimental research were employed on a roughly even basis in international journals. With respect to the type and subject of research, music perception and recent trends on the subject of musical interest and aptitude took up the majority of domestic journals, while international journals focused on music intervention, music perception and cognition with musical influences and experiences. The participants in both domestic and international journals were children, adolescents and adults, while the elderly were not observed. In the factors of impairment, research on people with total blindness or low vision were conducted frequently, but those with adventitious vision loss or multiple impairments were rarely performed. This study could be meaningful to suggest the direction of further studies, through the investigation of research trends in music and people with visual impairments.
