Association between Coffee Consumption and Bone Mineral Density in Korean Men Aged 50 Years and Older: A Cross Sectional Analysis of Korea National Health and Nutrition Examination Survey 2011

Background@#Coffee is the most commonly consumed beverage worldwide and has a variety of health benefits. However, the relationship between coffee consumption and bone mineral density (BMD) is still controversial. This study aimed to assess the associations between coffee consumption and BMD in Korean men aged 50 years and older. @*Methods@#The study included 271 Korean men aged 50 years and older from the Fourth Korea National Health and Nutrition Examination Survey 2011. Coffee consumption frequency was assessed using a questionnaire and categorized as follows: none, ≤1 cup/day, 2 cups/day, or 3 cups/day. The BMD of the total femur, femur neck, and lumbar spine were compared based on coffee consumption frequency. Multiple logistic regression analysis was used to analyze the association between coffee consumption and impaired bone health (osteopenia or osteoporosis). @*Results@#The BMD of the total femur and femur neck significantly increased with higher coffee consumption (P<0.001). Participants with the highest coffee consumption had the lowest odds ratio for osteopenia or osteoporosis of the total femur and femur neck (P<0.001 and P<0.05, respectively). After adjusting for all confounding factors, this trend remained consistent in the femur neck (P<0.05); drinking 2 cups of coffee per day was found to be associated with the lowest risk of osteopenia or osteoporosis of the total femur. @*Conclusion@#Coffee consumption was found to decrease the risk of osteopenia or osteoporosis of the total femur and femur neck in Korean men aged 50 years and older.

Community-Based Cardiac Rehabilitation Conducted in a Public Health Center in South Korea: A Preliminary Study

Objective@#To evaluate the safety and effectiveness of the community-based cardiac rehabilitation (CBCR) program that we had developed. @*Methods@#Individuals aged >40 years with cardiovascular disease or its risk factors who were residing in a rural area were recruited as study subjects. The CBCR program, which consisted of 10 education sessions and 20 weeks of customized exercises (twice a week), was conducted in a public health center for 22 weeks. Comprehensive outcomes including body weight, blood glucose level, and 6-minute walk distance (6MWD) were measured at baseline, 11th week, and completion. Furthermore, the outcomes of young-old (65–74 years) and old-old (≥75 years) female subjects were compared. @*Results@#Of 31 subjects, 21 completed the program (completion rate, 67.7%). No adverse events were observed, and none of the subjects discontinued the exercise program because of chest pain, dyspnea, and increased blood pressure. Body weight and blood glucose level were significantly decreased, and 6MWD was significantly increased following program implementation (p<0.05). Both young-old and old-old women exhibited an improvement in blood glucose level and 6MWD test (p<0.05). @*Conclusion@#We reported the results of the first attempted CBCR in South Korea that was implemented without adverse events during the entire program. Improved aerobic exercise ability and reduced risk factors in all participants were observed. These improvements were also achieved by older adults aged ≥75 years.

Relationship between Coffee Consumption and Dry Eye Syndrome in Korean Adults: 2010–2011 Korean National Health and Nutrition Examination Survey

BACKGROUND: Dry eye is a common disease, and coffee is a popular beverage that is heavily consumed in Korea and worldwide. We examined the correlation between coffee consumption and dry eye.METHODS: This study was performed using data from the 5th Korean National Health and Nutrition Examination Survey, which was a cross-sectional study of the Korean population conducted from 24 months. We included adults aged ≥19 years who underwent ophthalmologic examination and excluded those who had comorbid conditions with dry eye. The subjects were divided into dry eye and control groups. The dry eye group consisted of those who had been clinically diagnosed with dry eye. A multiple logistic regression analysis was conducted to determine the correlation between coffee consumption and dry eye.RESULTS: An inverse correlation was found between coffee consumption and dry eye in the group that consumed 3 cups of coffee a day (P=0.001). However, after multivariate adjustment, the statistical significance of the correlation disappeared (P=0.283).CONCLUSION: Consumption of 3 cups of coffee a day in comparison to non-consumption group was negatively correlated with dry eye in an univariate analysis model, but the correlation was not statistically significant after adjusting for age, sex, body mass index, smoking, binge drinking, sun exposure time and history of eye surgery.

Evaluation of a Community-based participatory professional periodontal care program for hypertension and diabetes patients / 대한구강보건학회지

OBJECTIVES: To evaluate the Community-Based Participatory Research (CBPR) professional periodontal care program model for patients with hypertension and diabetes. METHODS: This descriptive case study included 151 participants of the professional periodontal care program. The CBPR-based professional periodontal care program consists of 5-steps: ‘Issue identification and prioritization’ (Step 1), ‘Strategy development’ (Step 2), ‘Entry into community’ (Step 3), ‘Implementation’ (Step 4), and ‘Transition’ (Step 5). Quantitative data were analyzed using frequency analysis, and descriptive data with PASW 23.0 (SPSS Inc., Chicago, IL, USA). The results of the Focus group interview (FGI) were classified as ‘general opinions regarding the program planning and operation receptiveness’, ‘sustainability’, ‘potential spread of the program’, and ‘improvement of program’. The interviews were qualitative research involving seven people. RESULTS: 1. Participants increased their interest in health and oral health by managing their hypertension, diabetes, and periodontal disease using community resources. Through this, healthy practices and improved awareness helped to prevent complications and manage periodontal diseases. 2. Community organizations actively cooperated, resulting in positive changes in oral health practices (increased registration of patients in education centers for hypertension and diabetes, and increased number of patients visiting the local dental clinic). In the future, it was positive to participate in the program continuously. CONCLUSIONS: The most important step is ‘Entry into community’, which has led to active participation and cooperation of community organizations and participants. Therefore, community organizations and strategy development should be discussed, and the role of community leaders should be emphasized to build cooperative relationships. In addition, participation in and collaboration with health-based projects should be achieved through a search of various community organizations.

Accuracy of Korean-Mini-Mental Status Examination Based on Seoul Neuro-Psychological Screening Battery II Results / 가정의학회지

BACKGROUND: The Korean-Mini-Mental Status Examination (K-MMSE) is a dementia-screening test that can be easily applied in both community and clinical settings. However, in 20% to 30% of cases, the K-MMSE produces a false negative response. This suggests that it is necessary to evaluate the accuracy of K-MMSE as a screening test for dementia, which can be achieved through comparison of K-MMSE and Seoul Neuropsychological Screening Battery (SNSB)-II results. METHODS: The study included 713 subjects (male 534, female 179; mean age, 69.3±6.9 years). All subjects were assessed using K-MMSE and SNSB-II tests, the results of which were divided into normal and abnormal in 15 percentile standards. RESULTS: The sensitivity of the K-MMSE was 48.7%, with a specificity of 89.9%. The incidence of false positive and negative results totaled 10.1% and 51.2%, respectively. In addition, the positive predictive value of the K-MMSE was 87.1%, while the negative predictive value was 55.6%. The false-negative group showed cognitive impairments in regions of memory and executive function. Subsequently, in the false-positive group, subjects demonstrated reduced performance in memory recall, time orientation, attention, and calculation of K-MMSE items. CONCLUSION: The results obtained in the study suggest that cognitive function might still be impaired even if an individual obtained a normal score on the K-MMSE. If the K-MMSE is combined with tests of memory or executive function, the accuracy of dementia diagnosis could be greatly improved.

Survival Prediction in Terminally Ill Cancer Patients: Laboratory Variables and Prospective Validation of The Palliative Prognostic Index / 대한내과학회지

BACKGROUND/AIMS: The palliative prognostic index (PPI) was designed to predict life expectancy based on clinical symptoms. In this study, a PPI was constructed and used with other biological parameters to predict 3-week survival in patients with advanced cancer. METHODS: The study included 222 patients. The PPI was constructed with five variables (performance status, oral intake, edema, dyspnea at rest, and delirium). PPI scores were grouped as follows: 4 (group 1); > 4 and 6 (group 3). At admission, seven biological variables (white blood cell count, lymphocyte, C-reactive protein [CRP], bilirubin, albumin, creatinine, and lactate dehydrogenase) were measured. RESULTS: The overall survival duration was 50 days in group 1, 22 days in group 2, and 14 days in groups 3. Using the PPI, a survival of 6 and increases in serum bilirubin and CRP levels. Furthermore, the 3-week survival rate in patients with hepatopancreatobiliary cancer was more accurately predicted using a combination of the PPI, CRP, and serum bilirubin levels. CONCLUSIONS: Although a PPI has limitations, it can be quickly applied to determine survival duration in patients admitted to hospice and accurately predicts 3-week survival. Furthermore, bilirubin and CRP are useful factors for predicting 3-week survival in patients with gastrointestinal cancer, including hepatopancreatobiliary cancer.

Depression Level among Family Caregivers of Hospice Patients / 가정의학회지

BACKGROUND: It is expected that the number of families who provide caregiving for hospice patients will be increased in this society. Family caregiver will have fi nancial, psychological, social burden and stress related to this responsibility. Hospice patients, facing death, need not only biomedical therapy, but also systematic and continuous treatments such as mental or psycho-social intervention. The purpose of this study was to investigate the family caregiver's depression level and the associated factors. METHODS: The survey was conducted with 62 family caregivers of the hospice patients who had been hospitalized at the Gwangju Veterans Hospital from December 2005 to May 2006. The questionnaire consisted of the general characteristics of the subjects, Beck's depression inventory (BDI) evaluating the depression level and family APGAR score evaluating the family function. RESULTS: The mean age of the subjects was 58.2 years. The relationship with patients as 'spouse' accounted for 42 individuals (67.7%). The mean (+/- SD) BDI score was 25.3 (+/- 10.1) points and 58 percent of the subjects were suggested to have depression tendency (> or = 21 point). There was no relationship between the caregiver's depression level and their gender, religion, household income and Family APGAR score. However, the depression level was signifi cant related to the total caregiving duration (P = 0.001), visiting frequency of visitors (P = 0.004) and caregiving hours per day (P = 0.005). CONCLUSION: More than half of the family caregivers were suggested to have depression tendency. The depression level was infl uenced by the burden of caregiving and the visiting frequency of visitors. There is a need to activate social resources to share the burden of caregiving and to develop continuous and comprehensive care for hospice patients and their families.
