Relationship between Depression and Glycated Hemoglobin: Analysis Based on the 2019 Korea National Health and Nutrition Examination Survey / 우울ㆍ조울병

Background@#The goal of this study is to investigate the relationship between depression and glycated hemoglobin in the general Korean population. @*Methods@#Adults aged 19 to 80 years were surveyed as part of the 2019 Korea National Health and Nutrition Examination Survey. A total of 4,831 people were chosen to complete the health questionnaire, provide their body mass index, and get a HbA1c blood test. The general characteristics of groups with high and low glycated hemoglobin were identified. To find out the correlation between depression diagnosis and the general population with high glycated hemoglobin, a chi-square test was carried out. A t-test was also used to compare the means of glycated hemoglobin between the groups diagnosed with and not diagnosed with depression. In analyzing the relationship between depression and glycated hemoglobin, analysis of covariance was performed by adjusting the effects for demographic factors. @*Results@#Sex, age, income level, education level, drinking, smoking, exercise, and body mass index are all factors that influence glycated hemoglobin. The mean glycated hemoglobin was high in the group diagnosed with depression. The relationship between depression and glycated hemoglobin could not be confirmed using logistic regression after controlling for confounding variables. @*Conclusion@#There was no significant correlation between depression and glycated hemoglobin in the general population of Korea based on the results of this study.

Introduction of America’s Health Systems Science Education and Its Criticism / 의사학

Recently, Korean medical education circles have proposed a fullscale introduction of America’s health systems science to replace the existing medical humanities education in Korea. The so-called Flexner education system, formed in the early 20th century, was centered on basic and clinical sciences. America’s health systems science education was introduced to supplement the system. The full-scale introduction of health systems science has been promoted, mainly by the Korean Association of Medical Colleges. However, it does not fit into the current circumstance of Korean medical education circles. It is deemed that there are political reasons behind the push – the alignment of interests between the medical education circles and the government.This study first examined the social and cultural circumstances behind the emergence of health systems science in America, focusing on pragmatism, a native American ideology, to critique the background of the introduction of the American system. It also discussed the negative aspects of pragmatism in American medical education in the cases of American educators Ralph Tyler and Abraham Flexner. Then, it specifically examined the background and reasons for introducing America’s health systems science to Korea and discussed the problems of directly introducing the health systems science to Korea without any adaptation process through a comparative analysis with existing medical humanities. Finally, it suggested a more desirable adaptation form of health systems science that can be considered for its implementation in Korea.

A Study on the Relationship among Obesity, Suicide Plans, and Suicide Attempts: The 2018 Korea National Health and Nutrition Examination Survey / 우울ㆍ조울병

Background@#This study explores the correlation among obesity, suicide plans, and suicide attempts in adults over 19 years of age in South Korea. @*Methods@#The study used data from adults who had participated in the 2018 Korea National Health and Nutrition Examination Survey. Obesity was defined as having a body mass index of ≥25 kg/m 2 . To identify differences between the characteristics of those who had reported suicide plans and attempts, a complex sample chi-square test was conducted. To analyze the effect of obesity on suicide plans and attempts, a logistic regression analysis was performed. @*Results@#There was no significant difference in the rate of suicide plans in one year between obese and non-obese groups; however, the rate of actual suicide attempts was significantly high in the obese group (p<0.050). After correcting for variables that were significantly different between the groups, obesity was found to have no significant effect on suicide plans but was linked to a significant increase in suicide attempts (odds ratio=3.355, p=0.008). @*Conclusion@#Obesity was found to have no effect on the suicide planning rate; however, the probability of a suicide attempt was high in obese adults.

Lack of Association between Metabolic Syndrome and Depression in Korean Adults: Analysis Based on the 2016 and 2018 Korean National Health and Nutrition Examination Surveys / 우울ㆍ조울병

Background@#This study aims to investigate the relationship between metabolic syndrome and depression in Korean adults using data from the 2016 and 2018 Korean National Health and Nutrition Examination Surveys (KNHANES). @*Methods@#The total number of participants in the 7th period 1st year (2016) and 3rd year (2018) surveys of KNHANES was 16142. This study was conducted with 10,722 subjects who met the diagnostic criteria for metabolic syndrome and responded to the Patient Health Questionnaire-9 (PHQ-9). Analysis of covariance was used to adjust the differences due to demographic factors, laboratory findings, and underlying diseases to understand the relationship between metabolic syndrome and PHQ-9 scores, if any. @*Results@#The prevalence of metabolic syndrome was determined to be 25.6% in this study. The PHQ-9 scores with and without metabolic syndrome were 2.56 and 2.48, respectively, and there was no significant difference when the confounding variable was corrected (p=0.406). According to the analysis of each PHQ-9 item and metabolic syndrome, the results were not significant. @*Conclusion@#In this cross-sectional study conducted in Korean adults, no significant correlation was found between metabolic syndrome and depression.

Perception of and attitude toward ethical issues among Korean occupational physicians

BACKGROUND: Occupational physicians (OPs) have complex relationships with employees, employers, and the general public. OPs may have simultaneous obligations towards third parties, which can lead to variable conflicts of interests. Among the various studies of ethical issues related to OPs, few have focused on the Korean OPs. The aim of the present survey was to investigate the ethical contexts, the practical resolutions, and the ethical principles for the Korean OPs. METHODS: An email with a self-administered questionnaire was sent to members of the Korean Society of Occupational and Environmental Medicine, comprising 150 specialists and 130 residents. The questionnaire was also distributed to 52 specialists and 46 residents who attended the annual meeting of the Korean Association of Occupational and Environmental Clinics in October 2015, and to 240 specialists by uploading the questionnaire to the online community ‘oem-doctors’ in February 2016. The responses to each question (perception of general ethical conflicts, recognition of various ethical codes for OPs, core professional values in ethics of occupational medicine, and a mock case study) were compared between specialists and residents by the chi-squared test and Fisher’s exact test. RESULTS: Responses were received from 80 specialists and 71 residents. Most participants had experienced ethical conflicts at work and felt the need for systematic education and training. OPs suffered the most ethical conflicts in decisions regarding occupational health examination and evaluation for work relatedness. Over 60% of total participants were unaware of the ethical codes of other countries. Participants thought ‘consideration of worker’s health and safety’ (26.0%) and ‘neutrality’ (24.7%) as the prominent ethical values in professionality ofoccupational medicine. In mock cases, participants chose beneficence and justice for fitness for work and confidential information acquired while on duty, and beneficence and respect for autonomy in pre-placement examinations. CONCLUSIONS: This study evaluated the current perception of and attitude toward ethical issues among the Korean OPs. These findings will facilitate the development of a code of ethics and the ethical decision-making program forthe Korean OPs.
