The present study evaluated the effects of fermented whey protein using kimchi lactic acid bacteria Lactobacillus casei DK211 on skeletal muscle mass, muscle strength, and physical performance in healthy middle-aged males performing regular resistance exercises. Effective protein supplementation and regular exercise are two important factors for improving muscle health. Therefore, in this study, the effects of consuming fermented whey protein twice a day were investigated and compared with that of non-fermented supplementation. Forty-eight males (average age 44.8) were randomly assigned to two groups: Fermented whey protein supplementation (FWPS) and non-fermented whey protein concentration supplementation (WPCS) groups. Each group ingested 37 g of FWPS or WPCS twice a day for eight weeks. Body composition, muscle strength, and physical performance were assessed pre- and post-intervention. Independent t-tests or chi-square tests for the categorical variables were performed for analyzing the observations. FWPS was effective in promoting the physical performance in dynamic balance measurement and muscle health, indicated through the increment in grip strength (left), upper arm circumference, and flat leg circumference from the baseline. However, similar improvements were not observed in the WPCS group. These results imply that whey protein fermented by L. casei DK211 is an effective protein supplement for enhancing muscle health in males performing regular resistance exercises.

Cardiac resynchronization therapy (CRT) is a new treatment for refractory heart failure. However, most patients with heart failure treated with CRT are adults, middle-aged or older with idiopathic or ischemic dilated cardiomyopathy. We treated a 12-year-old boy, who was transferred after cardiac arrest, with dilated cardiomyopathy, left bundle-branch block, and ventricular tachycardia. We performed cardiac resynchronization therapy with a defibrillator (CRT-D). After CRT-D, left ventricular ejection fraction improved from 22% to 4 4% assessed by echocardiogram 1 year postoperatively. On electrocardiogram, QRS duration was shortened from 206 to 144 ms. The patient's clinical symptoms also improved. For pediatric patients with refractory heart failure and ventricular arrhythmia, CRT-D could be indicated as an effective therapeutic option.

Purpose: To identify the risk factors for suicidal ideation across the life cycle among Korean adults using data from 2015 Korean Psycho-social Anxiety Survey. Methods: The data were statistically analyzed using hierarchical logistic regression analysis. Results: The factors associated with suicidal ideation among the young adult group were education level (odds ratio [OR] 1.62, 95% confidence interval [CI] 1.05~2.49), self-esteem (OR 1.19, 95% CI 1.12~1.27), stress (OR 3.26, 95% CI 2.07~5.15), anger control problems (OR 3.58, 95% CI 2.34~5.50), and depression (OR 2.59, 95% CI 1.66~4.04) whereas among the middle-aged adults the factors were education level (OR 1.58, 95% CI 1.12~2.23), existence of a spouse (OR 2.55, 95% CI 1.72~3.78), self-esteem (OR 1.13, 95% CI 1.08~1.18), stress (OR 2.46, 95% CI 1.81~3.33), anger control problems (OR 1.70, 95% CI 1.22~2.36), and depression (OR 2.64, 95% CI 1.91~3.64). Among the older adult group the findings were the existence of a spouse (OR 2.16, 95% CI 1.37~3.39), self-esteem (OR 1.22, 95% CI 1.13~1.32), stress (OR 2.21, 95% CI 1.38~3.54), anxiety (OR 2.42, 95% CI 1.46~4.02), and depression (OR 2.48, 95% CI 1.30~4.72). Conclusion: The findings suggest that there may be a need for different suicide intervention programs to decrease suicidal ideation across the life cycle.

Objectives: Previous studies have shown that participation in social activities (SA) can prevent cognitive decline (CD) and that living arrangements (LA) can affect cognitive function. This study aimed to evaluate the effects of SA and LA on CD, as well as their interactions, using longitudinal data. Methods: Data were used from the 2006-2018 Korean Longitudinal Study for Aging, which followed 10 254 adults older than 45 years over a 12-year period. CD was defined as a ≥4-point score decrease in the Mini-Mental Status Exam over 2 years. We developed an extended Cox proportional hazards model for time-dependent covariates to estimate the hazard ratio (HR) of CD in 4 groups: (1) socially active and living with others, (2) socially active and living alone, (3) socially inactive and living with others (SILO), and (4) socially inactive and living alone (SILA). The model was stratified by gender and adjusted for important confounders. Results: The HR of CD was significantly higher in the SILO group in men (HR,1.36; 95% confidence interval [CI], 1.08 to 1.78) and in the SILA group in women (HR, 1.72; 95% CI, 1.08 to 2.75). However, the interaction term for gender was not significant. Conclusions: Among socially inactive elderly adults, the HR of CD was elevated in men who lived with others and in women who lived alone, although the interaction term for gender was not significant. Socially inactive men who live with others and socially inactive women who live alone are particularly encouraged to participate in SA to prevent CD.

Objectives: This study examined regional differences in the intake of dietary total fat and saturated fatty acid (SFA) and their food sources among Korean adults. We also investigated the associations of SFA intake with metabolic diseases by region. Methods: This study included 13,926 adults (≥ 19y) who participated in the 2016 ~ 2019 Korea National Health and Nutrition Examination Surveys. The regions were divided into urban and rural areas according to the administrative districts where the participants lived. Using dietary data obtained from a 24-h recall, intake of total fat and SFA and their food sources were assessed by region. Metabolic diseases included obesity, abdominal obesity, and elevated total cholesterol and their association with SFA intake by region were examined using multiple logistic regression. Results: Of the participants, 19.6% lived in rural areas. In urban areas, the total fat and SFA intakes were higher than in rural areas: 21.2% of energy (%E) came from total fat and 6.9%E from SFA in urban areas, whereas 18.0%E came from total fat and 5.8%E from SFA in rural areas. The percentage of participants who exceeded the dietary reference intakes for total fat and SFA in urban areas was 16.5% and 41.9%, respectively, but 43.4% of participants in rural areas showed lower intake levels for total fat compared to the reference level. Young adults did not show regional differences in fat intake, and the percentage of subjects who exceeded the reference for SFA was high both in urban (58.5%) and rural (55.7%) areas. Among middle-aged and older adults, intake of fatty acids except for n-3 fatty acid was significantly higher in urban areas than in rural areas. About 69% of older adults in rural areas showed a lower intake of total fat compared to the reference level. The food sources for total fat and SFA were meat, soybean oil, eggs, and milk in both areas. The intake of fat from eggs, milk, mayonnaise, and bread was higher in urban areas, but the intake of fat from white rice and coffee mix was higher in rural areas. The SFA intake was positively associated with elevated serum total cholesterol in urban areas (4th quartile vs. 1st quartile, OR: 1.22, 95% CI: 1.06-1.40, P for trend: 0.043), but not in rural areas. Conclusions: Regional differences in total fat and SFA intakes and their food sources were observed among Korean adults. Our findings may help plan nutritional strategies to ameliorate regional health disparities.

A study was performed to develop as a screening tool the Simple Evaluation Questionnaire for Screening the Over-weight-type Dietary Pattern in 30 to 49 Year Old Adults. We used the data from the 30 to 49 year old subjects who participated in the three surveys - the health behavior survey, the dietary habit survey and the food intake survey - as the National Health and Nutrition Survey 1998. The 3,598 adults were classified into to two body fatness groups of normal (including underweight) and overweight (including obese) on the basis of their relative body weight (RBW) When comparing variables between the two groups, significant differences were found in gender, education, job, employment status, perceived health status, sadness / depression state, stress level, age, number of diseases, age when overweightedness started, maximum body weight, sleep length, drinking pattern (yes/no) , amount of alcoholic drinks, frequency of intoxication or drunkeness, amount of alcoholic drinks when drunk, intensity of exercise, frequency of exercise, exercise duration, skipped meals, small meals and drug supplements. In terms of food intake, there were significant differences in the daily food intake in terms of breakfast, dinner, daily kimchi and dairy products. In terms of mealtimes, we found differences in the amount of cooked rice at breakfast, kimchi at lunch, soup / kuk at dinner, fresh vegetables for snacks, fried foods for snacks between breakfast and lunch, and fruits /juices for snacks between lunch and dinner. After developing questions with indicators and analyzing the indicators by logistic regression analysis three times, we chose 10 questions for a simple evaluation of dietary patterns for the overweight-type category in order to give one point each. Among them we selected two questions to add one additional point and one question to add two additional points. The average scores of the overweight and normal groups, as shown by the developed questionnaire, were $5.97 \pm 2.36 \pm 7.36 \pm 2.21$, respectively. A score of seven points was selected as the cut-off point. We examined the sensitivity, specificity and positive predictive value of the questionnaire to the results of 67%, 59% and 62%, respectively.

여가생활은 우리의 삶의 질을 향상시키는 중요한 역할을 한다. 그러나 기존 연구들은 여가가 미치는 영향력을 종단적으로 살펴보지 못하여 그 인과관계를 정확히 확인할 수 없었다. 특히나 평균 수명이 80세에 달하는 오늘날 중년기는 노년기 못지않게 새로운 관심 영역으로 떠오르고 있다. 이에 본 연구에서는 중년기의 여가생활이 행복과 건강에 미치는 영향력을 종단적으로 알아보았다. 연구에 참여한 사람들은 총 145명으로 서울지역에 거주하는 40세에서 65세 사이의 중년기에 해당하였다. 설문은 10개월을 간격으로 재실시 되었으며, 여가생활에 관한 질문은 여가만족도와 여가참여시간을 조사하였다. 행복과 건강에 관한 설문 내용은 주관적 행복감, 심리적 건강 불편증상, 신체적 건강 불편증상, 및 수면의 질 등으로 구성되었다. 분석방법은 위계적 회귀 분석을 이용하여 1차 조사 시기의 여가만족도와 여가참여시간이 1차 때의 각 종속변인을 통제한 후에도 여전히 2차 시기의 종속변인에 영향력을 미치는지를 조사하였다. 분석 결과, 여가만족도는 10개월 후의 주관적 행복감, 심리적 건강 불편 증상, 그리고 수면의 질에 유의미한 영향을 미치는 것으로 나타났고, 여가참여시간은 주관적 행복감, 심리적 및 신체적 건강 불편증상에 유의미하게 영향을 주었다. 이러한 연구 결과를 바탕으로 중년기 여가 활성화를 위한 방안과 본 연구의 시사점을 논의하였다.
