Objectives
Neck circumference is associated with a distinctive fat storage process that confers additional metabolic risk. Hence, this study aimed to investigate the correlation between baseline neck circumference and the incidence of cerebrovascular disease using a prospective community-based sample of Korean adults over 12 years of follow-up, after controlling for selected covariates. Methods: Participants with non-cerebrovascular disease were divided into 4 groups (Q1–Q4) based on their baseline neck circumference. Cox proportional hazards analysis was used to calculate hazard ratios and 95% confidence intervals (CIs) to evaluate the relationship between neck circumference and cerebrovascular disease incidence over a 12-year period. Results: Among this study’s 3,662 participants, 128 (3.50%) developed cerebrovascular disease. The incidence of cerebrovascular disease increased from 2.2% in Q1 to 4.3% in Q2, 2.5% in Q3, and 5.0% in Q4. When compared to Q1, the relative risks of cerebrovascular disease development were 0.57 (95% CI, 0.25–1.31), 0.86 (95% CI, 0.38–1.96), and 0.79 (95% CI, 0.30–2.07) in man and 1.86 (95% CI, 0.66–5.20), 3.50 (95% CI, 1.25–9.86), and 4.71 (95% CI, 1.50–14.77) in woman in Q2, Q3, and Q4, respectively, after adjusting for most risk factors related to cerebrovascular disease. Conclusion: The relationship between neck circumference and cerebrovascular disease was stronger in woman than in man, indicating potential differences between the sexes. These results are meaningful for evaluating and surveilling neck circumference as a promising tool for identifying subgroups of vulnerable and at-risk populations.

AbstractAbstract PDF
Objectives
Herpes simplex virus (HSV) infections have been reported in 60% to 95% of the adult population worldwide, making them one of the most common infectious conditions globally. HSV-1 and HSV-2 cause severe disease in immunocompromised patients. Therefore, the aim of this study was to provide information that could be used to reduce the incidence of genital herpes caused by HSV-1 and HSV-2.
Methods
From September 2018 to December 2020, 59,381 specimens were collected from outpatients across primary and secondary hospitals in Korea who requested U2Bio (Seoul, Korea) to conduct molecular biological testing of their samples for sexually transmitted infections. In this study, the positivity rates of HSV-1 and HSV-2 were analyzed according to age, sex, and specimen type.
Results
In the age-specific analysis of HSV-1, the highest positivity rate (0.58%) was observed in patients under 19 years of age, whereas the lowest positivity rate (0.08%) was observed in patients aged over 70 years. In the age-specific analysis of HSV-2, the highest positivity rate (2.53%) was likewise observed in patients under 19 years of age.
Conclusion
Our study identified differences in the infection rates of HSV-1 and HSV-2 depending on patients’ sex and age. These differences will be useful for improving disease prevention and control measures for HSV-1 and HSV-2.

AbstractAbstract PDF
Objectives
This study analyzed trends in foodborne and waterborne diseases in South Korea between 2015 and 2019.
Methods
The data consisted of information on outbreaks of waterborne and foodborne infectious diseases reported through the Korea Centers for Disease Control and Prevention (KCDC) system. We analyzed the trends and epidemiological aspects of outbreaks by month, place of occurrence, and causative pathogens in this observational study.
Results
The number of outbreaks has steadily increased over the last 5 years, but the number of cases per outbreak has followed a decreasing trend. Incidence at daycare centers and preschools has been steadily increasing over consecutive years.
Conclusion
The steady number of patients and decreasing number of cases per outbreak, even as the number of outbreaks has been increasing, suggest that the KCDC’s professional management system is operating effectively. It is necessary to continue improving the objectivity and efficiency of the management system and to carefully examine the increasing number of outbreaks in smaller-scale group catering facilities, such as daycare centers and preschools. Outbreaks can be prevented by closely examining those caused by unidentified pathogens and group outbreaks caused by other diseases, identifying problems, and supplementing the management system.

AbstractAbstract PDF

Since a novel beta-coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was first reported in December 2019, there has been a rapid global spread of the virus. Genomic surveillance was conducted on samples isolated from infected individuals to monitor the spread of genetic variants of SARS-CoV-2 in Korea. The Korea Disease Control and Prevention Agency performed whole genome sequencing of SARS-CoV-2 in Korea for 1 year (January 2020 to January 2021). A total of 2,488 SARS-CoV-2 cases were sequenced (including 648 cases from abroad). Initially, the prevalent clades of SARS-CoV-2 were the S and V clades, however, by March 2020, GH clade was the most dominant. Only international travelers were identified as having G or GR clades, and since the first variant 501Y.V1 was identified (from a traveler from the United Kingdom on December 22nd, 2020), a total of 27 variants of 501Y.V1, 501Y.V2, and 484K.V2 have been classified (as of January 25th, 2021). The results in this study indicated that quarantining of travelers entering Korea successfully prevented dissemination of the SARS-CoV-2 variants in Korea.

AbstractAbstract PDF
Objectives

Elderly adults are the demographic most likely to utilize emergency medical services (EMS). This study aimed to examine the difference in EMS utilization in subgroups of the elderly population by assessing the predictors for using EMS.

Methods

Using both descriptive and logistic regression analyses, this study analyses data from the 2014 Korean Health Panel Survey (n = 3,175).

Results

It was observed that certain predisposing factors such as age, sex, and marital status were significant predictors of EMS utilization. However, differences in EMS need do not fully account for the original differences observed between subgroups of elderly Koreans. While health status and disability were important predictors of elderly Koreans using EMS, place of residence did not account for subgroup differences. Nonetheless, place of residence remained particularly important predictors of EMS utilization for the elderly.

Conclusion

Emergency needs and resource availability are 2 main determinants for elderly Koreans using EMS. In addition, it was observed that the demographic subgroup profile of unmarried/divorced/separated/widowed men who were aged 75 and older was least likely to utilize EMS. Improving their resource availability to meet their EMS needs should be a top priority for national policy making to narrow elderly population subgroup differences.

AbstractAbstract PDF

This study aimed to determine the presence of SARS-CoV-2 on surfaces frequently touched by COVID-19 patients, and assess the scope of contamination and transmissibility in facilities where the outbreaks occurred. In the course of this epidemiological investigation, a total of 80 environmental specimens were collected from 6 hospitals (68 specimens) and 2 “mass facilities” (6 specimens from a rehabilitation center and 6 specimens from an apartment building complex). Specific reverse transcriptase-polymerase chain reaction targeting of RNA-dependent RNA polymerase, and envelope genes, were used to identify the presence of this novel coronavirus. The 68 specimens from 6 hospitals (A, B, C, D, E, and G), where prior disinfection/cleaning had been performed before environmental sampling, tested negative for SARS-CoV-2. However, 2 out of 12 specimens (16.7%) from 2 “mass facilities” (F and H), where prior disinfection/cleaning had not taken place, were positive for SARS-CoV-2 RNA polymerase, and envelope genes. These results suggest that prompt disinfection and cleaning of potentially contaminated surfaces is an effective infection control measure. By inactivating SARS-CoV-2 with disinfection/cleaning the infectivity and transmission of the virus is blocked. This investigation of environmental sampling may help in the understanding of risk assessment of the COVID-19 outbreak in “mass facilities” and provide guidance in using effective disinfectants on contaminated surfaces.

AbstractAbstract PDF
Objectives

This study was performed to test the association between lung function and type 2 diabetes mellitus (T2DM) in Korean patients.

Methods

Data from the 6th Korea National Health and Nutrition Examination Survey (2013 to 2015) was used in this study. There were 3,466 individuals aged between 40 and 80 years, with T2DM, who had a smoking and alcohol status listed, and blood analysis (including blood pressure), were included in this study. Lung function, measured by spirometer ventilatory dysfunction was categorized into 3 patterns: normal, restrictive ventilatory dysfunction, and obstructive ventilatory dysfunction (OVD).

Results

Based on multivariate logistic regression analysis, individuals with restrictive ventilatory dysfunction had an increased odds ratio (OR 1.615, 95% CI 1.137–2.294) for T2DM compared with individuals with normal ventilatory function, whereas OVD had no increase in the odds ratio (OR 1.169, 95 % CI 0.857–1.594). Model 1, which adjusted for age and gender, showed that the probability of having restrictive disorder was 1.559 times (95% CI 1.617–2.082) higher for prediabetes patients, and 2.320 times (95% CI 1.611–3.343) higher for T2DM patients, compared to normal individuals. For Model 4, which was fully adjusted for variables, the probability of having a restrictive disorder was 1.837 times higher for T2DM patients (95% CI 1.260–2.679).

Conclusion

Restrictive ventilatory dysfunction, but not OVD, was associated independently with T2DM.

AbstractAbstract PDF
Objectives

To estimate the number and risk of imported infections resulting from people visiting Asian and Latin American countries.

Methods

The dataset of visitors to 5 Asian countries with dengue were analyzed for 2016 and 2017, and in the Philippines, Thailand and Vietnam, imported cases of zika virus infection were also reported. For zika virus, a single imported case was reported from Brazil in 2016, and 2 imported cases reported from the Maldives in 2017. To understand the transmissibility in 5 Southeast Asian countries, the estimate of the force of infection, i.e., the hazard of infection per year and the average duration of travel has been extracted. Outbound travel numbers were retrieved from the World Tourism Organization, including business travelers.

Results

The incidence of imported dengue in 2016 was estimated at 7.46, 15.00, 2.14, 4.73 and 2.40 per 100,000 travelers visiting Philippines, Indonesia, Thailand, Malaysia and Vietnam, respectively. Similarly, 2.55, 1.65, 1.53, 1.86 and 1.70 per 100,000 travelers in 2017, respectively. It was estimated that there were 60.1 infections (range: from 16.8 to 150.7 infections) with zika virus in Brazil, 2016, and 345.6 infections (range: from 85.4 to 425.5 infections) with zika virus in the Maldives, 2017.

Conclusion

This study emphasizes that dengue and zika virus infections are mild in their nature, and a substantial number of infections may go undetected. An appropriate risk assessment of zika virus infection must use the estimated total size of infections.

AbstractAbstract PDF
Objectives

This study was performed to examine the effects of the Korean medicine healthcare program on stroke-related factors and self-care enhancement.

Methods

This study was a quasi-experimental, pretest-posttest nonequivalent control group design study (N = 58 participants), with 28 in the treatment group (Korean medicine health care program) and 30 in the control group (no intervention). The program was conducted twice a week for 2 hours, for a total of 12 weeks.

Results

There were statistically significant differences in systolic (p = 0.005) and diastolic blood pressure (p = 0.006), cholesterol (p < 0.001), blood glucose (p < 0.001), self-esteem (p = 0.001), self-efficacy (p < 0.001), health perception (p < 0.001), and the health behavior (p < 0.001) between the experimental group and the control group.

Conclusion

Thus, the Korean medicine healthcare program was effective in managing stroke-related factors and enhancing self-care, and should be actively used to develop community health promotion strategies to prevent strokes and prepare long-term measures.

Objectives

The aim of this study was to analyze research and development projects in mental health services in Korea, using priority evaluation of mental health promotion policies to determine direction of the service.

Methods

An online survey was conducted that targeted experts in the mental health service regarding promotion of mental health in Korea in 2016. The survey was based on 32 policy projects that resulted from 12 strategies according to 4 policy objectives.

Results

Analysis of 32 mental health projects were assessed regarding the possibility of technology development success, magnitude of the ripple effect, and necessity of a national response. It was observed that 3 policy projects relevant to suicide, had a high relative priority. This was followed by policies for improvement of health insurance and the medical benefit cost system, and policies for reinforcement of crisis psychological support such as those for disaster victims.

Conclusion

The prioritization of mental health services should place an emphasis on promotion of a healthy mental lifestyle, rehabilitation support for patients with serious mental illness, and reinforcement of social safety networks for suicide prevention.

Objectives

The aim of this study was to gather information about Korean Army soldiers’ attitude towards tuberculosis to enable the development of an informed educational program and potential intervention plans.

Methods

There were 500 male soldiers serving in the Korean Army who responded to questionnaires regarding knowledge of, attitudes towards, and preventive behavior towards tuberculosis. The questionnaires were collected between September 10 until October 1, 2014. Participants’ characteristic that influenced differences in knowledge, attitudes, and preventive behavior towards tuberculosis were compared by t test. Variables that influenced preventive behavior were identified by multiple regression analysis.

Results

The mean scores assessing knowledge of, attitude, and preventive behavior towards tuberculosis were 11.64 (± 4.03) out of 20 points, 3.21 (± 0.38) out of 4 points, and 2.88 (± 0.42) out of 4 points, respectively. Non-smokers were more knowledgeable about tuberculosis than smokers. Participants who had family or friends with tuberculosis had better knowledge and a more productive attitude to tuberculosis. Participants who were educated or obtained information about tuberculosis, received better scores in all areas of knowledge, attitude and preventive behavior compared to other participants. Non-smoking, family or friends who have had tuberculosis, obtaining information about tuberculosis, and positive attitudes towards treatment and preventive education had an explanatory power of 24.6% with regard to preventive behavior against tuberculosis.

Conclusion

More relatable, systemized education should be provided regularly to improve soldiers’ knowledge of, attitudes towards, and prevention against tuberculosis in the Republic of Korea Army.

AbstractAbstract PDF
Objectives

To investigate the chronological patterns of diseases in Northern Gyeonggi-do province, South Korea, and compare these with national data.

Methods

A National Health Insurance cohort based on the National Health Information Database (NHID Cohort 2002–2013) was used to perform a retrospective, population-based study (46,605,433 of the target population, of which 1,025,340 were randomly sampled) to identify disease patterns from 2002 to 2013. Common diseases including malaria, cancer (uterine cervix, urinary bladder, colon), diabetes mellitus, psychiatric disorders, hypertension, intracranial hemorrhage, bronchitis/bronchiolitis, peptic ulcer, and end stage renal disease were evaluated.

Results

Uterine cervix cancer, urinary bladder cancer and colon cancer had the greatest rate of increase in Northern Gyeonggi-do province compared with the rest of the country, but by 2013 the incidence of these cancers had dropped dramatically. Acute myocardial infarction and end stage renal disease also increased over the study period. Psychiatric disorders, diabetes mellitus, hypertension and peptic ulcers showed a gradual increase over time. No obvious differences were found for intracranial hemorrhage or bronchitis/bronchiolitis between the Northern Gyeonggi-do province and the remaining South Korean provinces. Malaria showed a unique time trend, only observed in the Northern Gyeonggi province, peaking in 2004, 2007 and 2009 to 2010.

Conclusion

This study showed that the Northern Gyeonggi-do province population had a different disease profile over time, compared with collated data for the remaining provinces in South Korea. “Big data” studies using the National Health Insurance cohort database can provide insight into the healthcare environment for healthcare providers, stakeholders and policymakers.

AbstractAbstract PDF
Objectives

This study aimed to develop a high-risk drinking scorecard using cross-sectional data from the 2014 Korea Community Health Survey.

Methods

Data were collected from records for 149,592 subjects who had participated in the Korea Community Health Survey conducted from 2014. The scorecard model was developed using data mining, a scorecard and points to double the odds approach for weighted multiple logistic regression.

Results

This study found that there were many major influencing factors for high-risk drinkers which included gender, age, educational level, occupation, whether they received health check-ups, depressive symptoms, over-moderate physical activity, mental stress, smoking status, obese status, and regular breakfast. Men in their thirties to fifties had a high risk of being a drinker and the risks in office workers and sales workers were high. Those individuals who were current smokers had a higher risk of drinking. In the scorecard results, the highest score range was observed for gender, age, educational level, and smoking status, suggesting that these were the most important risk factors.

Conclusion

A credit risk scorecard system can be applied to quantify the scoring method, not only to help the medical service provider to understand the meaning, but also to help the general public to understand the danger of high-risk drinking more easily.

Objectives

There is evidence to suggest that sedentary behavior is associated with a higher risk of metabolic disease. The aim of this study was to investigate cross-sectional joint associations of physical activity (PA) and screen time (ST), with the risk of obesity in Korean adults.

Methods

The Korea Media Panel Study consisted of a household interview and a self-administered diary survey on media usage over 3 days. ST (hours/day) was defined as the reported daily average hours spent watching television, computing (i.e., desktop, notebook, netbook, tablets), smartphone and video game console use. Cross-sectional associations of obesity (BMI ≥ 25 kg/m2) and the amount of daily ST and PA were examined by logistic regression models adjusting for other possible confounders including alcohol consumption, smoking, depressive symptoms and demographic information. There were 7,808 participants included in the analyses.

Results

Increased ST was significantly associated with the risk of obesity (controlling for other possible confounders), but PA level was not found to be significantly linked. Participants who engaged in screen time > 6 hours per day had a higher incidence of obesity.

Conclusion

This study provides evidence of the association between ST and the increased incidence of obesity measured by BMI, independent of PA amongst Korean adults.

Brief Report

AbstractAbstract PDF

The Japanese encephalitis (JE) vaccine was introduced to the national immunization program in 1985, which has led to a dramatic decrease in the number of reported cases, but JE continues to occur in foreign nationals residing in or traveling to Korea. Although the incidence is low, this study demonstrated that more Koreans were infected with JE than foreign-born expatriates. The incidence rates of Korean-born nationals were between 0.01 and 0.08 cases per 100,000. In contrast, the incidence rates of foreign-born nationals ranged between 0 and 0.26 cases per 100,000. The incidence rates clearly showed that foreign-born expatriates were more at risk, which underscores the importance of vaccination. We recommend heightened surveillance among JE-susceptible individuals and promote vaccination among foreign-born nationals living in Korea.
