Objectives: Although risk factors for coronary artery disease are also associated with increased carotid intima-media thickness (IMT), there is little information available on the asymptomatic, young adult population. We examined the association between multiple cardiovascular risk factors and the common carotid IMT in 280 young Korean adults. Methods: The data used for this study was obtained from 280 subjects (130 men and 150 women) aged 25 years who participated in the Kangwha Study follow-up examination in 2005. We measured cardiovascular risk factors, including anthropometries, blood pressure, blood chemistry, carotid ultrasonography, and reviewed questionnaires on health behaviors. Risk factors were defined as values above the sex-specific 75th percentile of systolic blood pressure, body mass index, total cholesterol/ high-density lipoprotein cholesterol ratio, fasting blood glucose and smoking status. Results: The mean carotid IMT${\pm}$standard deviation observed was $0.683{\pm}0.079mm$ in men and $0.678{\pm}0.067mm$ in women (p=0.567) and the evidence of plaque was not observed in any individuals. Mean carotid IMT increased with an increasing number of risk factors(p for trend <0.001) and carotid IMT values were 0.665 mm, 0.674 mm, 0.686 mm, 0.702 mm, and 0.748 mm for 0, 1, 2, 3, and 4 to 5 risk factors, respectively. The odds ratio for having the top quartile carotid IMT in men with 3 or more risk factors versus 0-2 risk factors was 5.09 (95% CI, 2.05-12.64). Conclusions: Current findings indicate the need for prevention and control of cardiovascular risk factors in young adults and more focus on those with multiple cardiovascular risk factors.

The current use of leading causes of death is an outmoded, misleading counterproductive measure of importance of disease. The 'new' concept of productive years of life discounted to the future and combined with morbidity, disability, and direct cost measures will give a much more meaningful, useful measure of the magnitude of disease problems in Korea. I am looking forward to seeing refinements and improvements on this technique carried out by some readers of this paper.

o The risk of being admitted with respiratory disease is increased by 9% on the Asian dust day o The risk of cardiovascular admission is increased by 5% o During the great dust event in 2002, the counts of respiratory admission seems to be increased, but we couldn't observed the epidemic of respiratory disease o The Asian dust events are weakly associated with daily mortality

Objectives: Emerging evidence indicates that sleep duration is associated with health outcomes. However, the relationship of sleep duration with long-term health is unclear. This study was designed to determine the relationship of sleep duration with mortality as a parameter for long-term health in a large prospective cohort study in Korea. Methods: The study population included 13 164 participants aged over 20 years from the Korean Multi-center Cancer Cohort study. Information on sleep duration was obtained through a structured questionnaire interview. The hazard ratios (HRs) and 95% confidence intervals (CIs) for mortality were estimated using a Cox regression model. The non-linear relationship between sleep duration and mortality was examined non-parametrically using restricted cubic splines. Results: The HRs for all-cause mortality showed a U-shape, with the lowest point at sleep duration of 7 to 8 hours. There was an increased risk of death among persons with sleep duration of ${\leq}5$ hours (HR, 1.21; 95% CI, 1.03 to 1.41) and of ${\geq}10$ hours (HR, 1.36; 95% CI, 1.07 to 1.72). In stratified analysis, this relationship of HR was seen in women and in participants aged ${\geq}60$ years. Risk of cardiovascular disease-specific mortality was associated with a sleep duration of ${\leq}5$ hours (HR, 1.40; 95% CI, 1.02 to 1.93). Risk of death from respiratory disease was associated with sleep duration at both extremes (${\leq}5$ and ${\geq}10$ hours). Conclusions: Sleep durations of 7 to 8 hours may be recommended to the public for a general healthy lifestyle in Korea.

Objectives: This study identifies the trends in possible and probable occupational disease among chromium workers and reviews the literature on domestic and foreign chromium workers to review the industries, biological exposure levels, and major results. Methods: The results of the Ministry of Employment and Labor's special health-screening program for hazard agents among workers from 2009 to 2019 were used. Also, the industries, biological exposure levels, and major results on chromium workers were reviewed using PubMed and RISS. Results: The average annual proportion of both possible and probable occupational disease for chromium workers has recently increased. The average annual proportion of possible and probable occupational disease that can occur was high for both men and women in their 60s or older by age and 10 to 14 years by work duration. By industry, possible occupational disease showed high in manufacturing. In the literature review, many electroplating-related chromium-workers reported high levels of exposure to blood and urine chromium, as did dental technicians; tannery, tile factory or glass mill workers; cement workers; and sodium bichromate workers. Furthermore, a number of main findings in recent studies have reported that chromium exposure is related to genetic toxicity among workers. Conclusions: In this study, the average annual rate of both possible and probable occupational disease in domestic chromium workers is increasing, and a body of literature shows that chromium exposure is related to genetic toxicity and associated indicators among workers, which requires more systematic study.
