This study investigated the relationship between hemoglobin concentration and the incidence of cardiovascular diseases (CVD). A total of 407,858 subjects (256,851 men, aged 30-94 yr), who underwent physical examination at 17 Korean nationwide health examination centers, was included in this study. Data regarding CVD incidence were obtained from the Korean National Health Insurance database. In Cox proportional hazard models, men with lower or higher hemoglobin level showed higher hazard ratios (HR) with total CVD (HR, 1.14; 95% Confidence interval [CI], 1.08-1.21 for the 1st quintile; HR, 1.14; 95% CI, 1.09-1.21 for the 5th quintile), ischemic heart disease (HR, 1.16; 95% CI, 1.07-1.26 for the 1st quintile; HR, 1.16; 95% CI, 1.07-1.25 for the 5th quintile), and stroke (HR, 1.13; 95% CI, 1.02-1.25 for the 1st quintile; HR, 1.18; 95% CI, 1.07-1.30 for the 5th quintile) compared to those with mid-level of hemoglobin (3rd quintile). Women with higher hemoglobin level showed higher HR with total CVD (HR, 1.15; 95% CI, 1.01-1.31 for pre-menopausal women; HR, 1.08; 95% CI, 1.01-1.16 for post-menopausal women). We found an independent U-shaped association between hemoglobin level and CVD incidence in Korean population.

In two UK hospitals, ADEs accounted for 6.5% of hospital admissions and patients admitted with ADEs were significantly older than patients without ADEs. 4) A US study also reported that ADEs are responsible for about 100,000 hospitalizations per year in adults ≥65 years of age and nearly half of these hospitalizations were among adults ≥80 years. 5) In addition, the prediction and detec

Background: Due to the increase in general health examination centers, health examination programs are becoming more diversified in Korea. Some of the general health examination tests, such as computed tomography, result in substantial levels of radiation exposure. However, the amount of radiation exposure from these examinations has not been studied in Korea. Thus, the aim of this study was to investigate the level of radiation exposure from general health examinations. Methods: Through the Korean Hospitals Association website and portal sites, 296 general health examination facilities were included in the study. The information about whether radiation-related tests are included in the health examination program of each facility was collected from their internet website. The radiation exposure dose for each test was obtained from the Database Construction Report by the Korean Institute of Nuclear Safety. Results:The mean base exposure dose of health examination programs from 296 health facilities was 2.49±2.50 mSv. The mean maximum exposure dose was 14.82±9.55 mSv (maximum 40.1 mSv). The maximum exposure dose was the highest at university-associated hospitals (21.63±7.54 mSv) and lowest at hospitals with ≤30 beds (7.84±7.64 mSv). The contribution of computed tomography on the maximum exposure dose was the highest of all examinations (72%). Conclusions: This study verified that examinees are exposed to substantial levels of radiation during general health examinations. It is necessary to establish evidence-based screening programs considering radiation exposure during general health examinations. Korean J Health Promot 2015;15(3):136-140

BackgroundThis study aimed to investigate the association between living arrangements and influenza vaccination among elderly South Korean subjects.MethodsWe used data from the fifth Korean National Health and Nutrition Examination Survey. Participants older than 65 years were included and categorized into 4 groups according to the type of living arrangement as follows: (1) living alone group; (2) living with a spouse group; (3) living with offspring (without spouse) group; and (4) living with other family members group. A total of 1,435 participants were included in this cross-sectional analysis.ResultsA lower vaccination rate was observed in the living with offspring (without spouse) group, whereas the living with a spouse group had higher rates of both seasonal and H1N1 influenza vaccination. After adjusting for age, sex, region, education level, income level, and number of comorbidities, the living with offspring (without spouse) group had a higher H1N1 vaccination non-receipt rate than the living alone group (odds ratio, 2.03; 95% confidence interval, 1.08-3.82).ConclusionInfluenza vaccination rates differed according to the type of living arrangement. Particularly, those living with offspring (without spouse) had the lowest H1N1 influenza vaccination rate compared to those with other living arrangements, and this difference was significant. Interventions to improve influenza vaccination coverage should target not only elderly persons who live alone, but also those living with offspring.
