Temporal Trends of the Prevalence of Abdominal Obesity and Metabolic Syndrome in Korean Children and Adolescents between 2007 and 2020.

Background: The prevalence of obesity in children and adolescents is increasing worldwide, which is of concern because obesity can lead to various complications such as metabolic syndrome (MS). Waist circumference (WC) and waist-height ratio (WHtR) are useful indicators of abdominal obesity and MS. In this study, we investigate trends in the prevalence of abdominal obesity and MS using two different references.

Reference Values for Waist Circumference and Waist-Height Ratio in Korean Children and Adolescents.

Background: Abdominal obesity, which is a strong indicator of cardiometabolic risk, is widely evaluated using waist circumference (WC) and waist-height ratio (WHtR). In Korea, the reference values for WC for children and adolescents were published in 2007 and need to be revised. Moreover, there is no reference for WHtR.

Long-term Exposure to PM10 Increases Lung Cancer Risks: A Cohort Analysis.

Purpose: Although lung cancer incidences in female never-smokers have increased, few studies focus on explicit investigation. We aimed to investigate the relationship between long-term exposure to ambient particulate matter sized 10 μm or less in diameter (PM10) and the incidence of lung cancer within different genders and smoking status populations.

Materials And Methods: We included Seoul metropolitan residents, aged between 20 and 65 years, who underwent a national health screening examination from 2005-2007 and were followed up until 2015.

Worry experienced during the 2015 Middle East Respiratory Syndrome (MERS) pandemic in Korea.

Background: Korea failed in its risk communication during the early stage of the Middle East Respiratory Syndrome (MERS) outbreak; consequently, it faced difficulties in managing MERS, while disease-related worry increased. Disease-related worry can help disease prevention and management, but can also have a detrimental effect. This study measured the overall level of disease-related worry during the MERS outbreak period in Korea and the influencing factors and levels of disease-related worry during key outbreak periods.

Low Serum Albumin Level, Male Sex, and Total Gastrectomy Are Risk Factors of Severe Postoperative Complications in Elderly Gastric Cancer Patients.

Purpose: It is well known that old age is a risk factor for postoperative complications. Therefore, this study aimed to explore the risk factors for poor postoperative surgical outcomes in elderly gastric cancer patients.

Materials And Methods: Between January 2006 and December 2015, 247 elderly gastric cancer patients who underwent curative gastrectomy were reviewed.

Assessment of noise measurements made with a continuous monitoring in time.

The World Health Organization has stated that hearing loss is one of the top 10 health problems worldwide and that noise-induced hearing loss is the leading occupational disease. This work evaluated the noise exposure levels of several job categories for 24-h periods over 7 days to determine the contribution of each microenvironment to total noise exposure. The noise exposure levels of 47 individuals were continuously measured using personal noise dosimeters in metropolitan Seoul, Korea.
