OBJECTIVES
The aim of this study was to evaluate the disease burden of prostate cancer (PC) and assess key influencing factors associated with the disease expenditures of PC in the United States.
METHODS
The total deaths, incidence, prevalence, and disability-adjusted life-years of PC were obtained from the Global Burden of Disease Study 2019. The Medical Expenditure Panel Survey was used to estimate healthcare expenditures and productivity loss and to investigate patterns of payment and use of healthcare resources in the United States. A multivariable logistic regression model was conducted to identify key factors influencing expenditures.
RESULTS
For patients aged 50 and older, the burden for all age groups showed a modest increase over the 6-year period. Annual medical expenditures were estimated to range from US$24.8 billion to US$39.2 billion from 2014 to 2019. The annual loss in productivity for patients was approximately US$1,200. The top 3 major components of medical costs were hospital inpatient stays, prescription medicines, and office-based visits. Medicare was the largest source of payments for survivors. In terms of drug consumption, genitourinary tract agents (57.0%) and antineoplastics (18.6%) were the main therapeutic drugs. High medical expenditures were positively associated with age (p=0.005), having private health insurance (p=0.016), more comorbidities, not currently smoking (p=0.001), and patient self-perception of fair/poor health status (p<0.001).
CONCLUSIONS
From 2014 to 2019, the national real-world data of PC revealed that the disease burden in the United States continued to increase, which was partly related to patient characteristics.; Summary

Key Message
This study quantified the disease burden of prostate cancer and showed that the burden is still substantial in the US from 2014-2019. This study explored the patients’ payment sources for healthcare expenditures and identified the top types of healthcare service expenditure for PC survivors. Moreover, this study also assessed key influencing factors for the high healthcare expenditures, which were associated with some demographic characteristics, such as age, having private health insurance, more comorbidities, smoking situation, and patients’ self-perceived health status.

Abstract

OBJECTIVES
Coronavirus disease 2019 (COVID-19) and the associated social distancing, limited freedom, and fear of an uncertain future are expected to have substantial mental health effects. We investigated mental health responses in the community during the first year of the COVID-19 pandemic in Korea.

METHODS

We used 2016-2019 and 2020 data from the Korea National Health and Nutrition Examination Survey (KNHANES) to assess pre-pandemic and pandemic mental health status, respectively, in terms of perceived severe stress, depression, and suicidal plans. All analyses were gender-stratified. Pre-specified subgroup analyses were performed according to age, employment status, and household income.

RESULTS

The percentage of Korean adults with suicidal plans increased significantly from 1.3%p (95% confidence interval [CI], 1.1 to 1.5) in 2016-2019 to 1.8%p (95% CI, 1.4 to 2.1) in 2020. Individuals in their 20s and 40s showed a marked increase in suicidal plans (1.2%p; 95% CI, 0.0 to 2.3 and 0.9%p; 95% CI, 0.0 to 1.8, respectively). In men, depression and perceived severe stress increased significantly from pre-COVID-19 to 2020. There was a 2.4%p (95% CI, 0.8 to 4.0) increase in depression among standard workers and a 2.9%p increase in depression in individuals in the second-highest quintile of household income from 2016 and 2018 to 2020.

CONCLUSIONS

As COVID-19 continued, mental health issues such as suicidal plans, depression, and severe stress increased significantly in young men and people in the second-highest quintile of household income. Proactive community mental health efforts are needed to prevent increases in the suicide rate resulting from prolonged exposure to the COVID-19 pandemic.

Summary

Korean summary
코로나19 이전에 비해 코로나19 유행 첫 해 동안에 전체 인구에서 자살 계획 유병율이 유의하게 증가하였고 특히 20대-40대에서 증가 비율이 높았다. PHQ-9으로 측정한 우울증 유병율은 전체 남성에서 증가하였고 특히 30대 남성에서 증가 비율이 높았다. 코로나19 영향으로 자살 계획과 우울증과 같은 정신 건강 문제가 젊은 성인에서 크게 증가하였기 때문에 이러한 정신건강 문제가 자살률 증가로 이어지는 것을 방지하기 위해 국가적 차원의 체계적인 정책과 적극적인 지역사회 정신건강 중재가 필요하다.

Key Message
There was a significant increase in the prevalence of suicidal plan in the overall population during the first year of COVID-19 pandemic compared to pre-COVID-19. In particular, suicide plans increased among those in their 20s and 40s. The prevalence of PHQ-9 detected depression increased in all men, especially among men in their 30s. As mental health problems such as suicide planning and depression have significantly increased among young adults due to the impact of COVID-19, systematic policies at the national level and active community mental health interventions are needed to prevent these mental health problems from leading to an increase in suicide rates.

Abstract Summary PDF: Abstract
In 2019, a child’s death in Korea led to legislation that imposed stricter penalties for school zone traffic violations. We assessed the impact of that legislation using 2017-2022 Traffic Accident Analysis System data. Adjusted analyses revealed a significant decline in severe injuries in school zones, decreasing from 11 cases to 8 cases per month (p=0.017). The legislation correlated with a reduced risk of all child traffic injuries (risk ratio, 0.987; 95% confidence interval, 0.977 to 0.997; p=0.002), indicating its efficacy in curbing accidents.; Summary

Key Message
Revised legislation in Korea, following a child’s tragic death, enforced stricter penalties for school zone traffic violations. Analysis of 2017-2022 data showed a significant decrease in severe injuries from 11 to 8 cases monthly (p=0.017). The legislation also reduced the risk of all child traffic injuries (risk ratio, 0.987; 95% CI, 0.977 to 0.997; p=0.002), demonstrating its effectiveness in preventing accidents. This study underscores the legislation’s positive impact on child safety in school zones, emphasizing the importance of ongoing enforcement efforts for road safety.

Abstract

OBJECTIVES
The aim of this study was to investigate the prevalence and risk factors of poor mental health in the general Korean population during the coronavirus disease 2019 (COVID-19) pandemic.

METHODS

This cross-sectional, population-based, online survey-based study was conducted from November 5 to 20, 2020 and included adults aged 20-49 years in Chungnam Province, Korea. A total of 549 adults were included.

RESULTS

In total, 18.8% of the participants had symptoms of depression, 10.6% had symptoms of anxiety, and 5.1% had a high level of perceived stress during the COVID-19 pandemic. Higher levels of stress (odds ratio [OR], 3.13; 95% confidence interval [CI], 1.13 to 8.67), anxiety (OR, 2.33; 95% CI, 1.09 to 4.49), and depression (OR, 3.00; 95% CI, 1.64 to 5.50) were found among never married, widowed, divorced, and separated people than among married/cohabiting/partnered participants. Participants who felt increased stress at home during the COVID-19 outbreak reported more depression (OR, 2.45; 95% CI, 1.49 to 4.05) and anxiety (OR, 2.42; 95% CI, 1.31 to 4.50). Women had higher risks of anxiety (OR, 1.97; 95% CI, 1.09 to 3.58) and stress (OR, 6.40; 95% CI, 2.30 to 17.85) than men. Participants with the highest household income were less likely to report symptoms of stress than those with the lowest household income (OR, 0.24; 95% CI, 0.06 to 0.96).

CONCLUSIONS

The participants in this study exhibited poor mental health index scores, suggesting that some people are at risk for mental health problems during the COVID-19 pandemic. Being married was independently and significantly associated with a lower likelihood of depression, anxiety, and stress.

Summary

Korean summary
이 연구는 코로나-19 유행 기간 동안 정신건강 현황과 위험 요인을 알아보기 위한 단면연구이다. 코로나 19 유행 이후 가정내 스트레스가 증가했다고 응답한 경우 우울증과 불안감의 유병률이 높았다. 반면, 남성인 경우, 결혼했거나 동거인과 같이 살고 있는 경우에는 우울증, 불안 또는 스트레스의 유병률이 통계적으로 유의하게 낮았다. 마스크 착용하기, 비대면 활동 증가, 또는 사회적 거리두기 등 코로나 19의 유행을 통제하기 위한 많은 정책은 개인의 일상생활과 정신건강에 많은 영향을 미쳤다. 이 연구는 취약 집단을 발굴하고, 정신건강 회복을 위한 전략을 개발하는데 기초자료를 제공할 수 있다.

Key Message
This study revealed high prevalence rates of depression, anxiety, and stress in the general population of Korea aged 20-49 years during the COVID-19 pandemic. Participants who felt increased stress at home reported more depression and anxiety. Men and being married were significantly associated with a lower likelihood of depression, anxiety, or stress. The COVID-19 pandemic has been a traumatic event. In addition, the policies created to prevent its spread have disrupted daily living for the general population. Implementing strategies to promote resilience and support psychologically vulnerable individuals during the COVID-19 crisis is of fundamental importance.

Abstract

OBJECTIVES
We investigated trends in obesity, hypertension, diabetes, and hypercholesterolemia before and during the coronavirus disease 2019 (COVID-19) pandemic in the Korean adult population.

METHODS

Data from 60,098 participants in the Korea National Health and Nutritional Examination Survey between 2011 and 2020 aged ≥19 were used. The age-standardized prevalence and annual percent changes (APCs) were calculated for obesity (body mass index ≥25 kg/m2), hypertension (systolic/diastolic blood pressure ≥140/90 mmHg or under treatment), diabetes (hemoglobin A1c ≥6.5%, fasting glucose ≥126 mg/dL, physician diagnosis, or under treatment), and hypercholesterolemia (total cholesterol ≥240 mg/dL or under treatment).

RESULTS

Over the past decade (2011-2020), the age-standardized APCs (95% confidence intervals) for obesity, hypertension, diabetes and hypercholesterolemia were 3.0% (2.1 to 3.8), 0.1% (-1.3 to 1.5), 1.5% (-1.0 to 4.0) and 8.0% (5.7 to 10.3), respectively, in men; and -0.2% (-1.5 to 1.2), -0.5% (-1.9 to 0.9), -0.1% (-2.3 to 2.2) and 5.9% (3.9 to 8.0), respectively, in women. In 2020 compared to the previous 3 years (2017-2019), obesity, hypertension, diabetes, and hypercholesterolemia increased in men (6.0, 1.8, 1.9, and 2.8%p, respectively), but an increase was not apparent in women (2.5, -1.1, 0.8, and 0.7%p, respectively).

CONCLUSIONS

An increase in major chronic diseases was observed in Korean adults, especially men, during the COVID-19 pandemic. In order to reduce the burden of cardiovascular and metabolic diseases in the future, effective intervention strategies need to be developed according to the characteristics of the target groups.

Summary

Korean summary
한국인의 비만, 고혈압, 당뇨 및 고지혈증 유병률은 지난 10년간 전반적으로 증가하는 경향을 보였다. 특히, 코로나 19가 유행한 2020년에 남성의 주요 만성질환 유병률은 지난 3년 평균치와 비교하였을 때 모두 유의하게 증가하였다. 반면, 여성에서 만성질환 유병률의 뚜렷한 증가는 관찰되지 않았다.

Key Message
During COVID-19 pandemic, the overall increase in major chronic diseases was observed in Korean adults, and this trend was prominent in men. Accordingly, target-specific intervention strategies need to be developed to reduce the burden of cardiovascular and metabolic diseases in the future.

Abstract

OBJECTIVES
Q fever, caused by the bacterium, is a major zoonotic disease around the world. This disease is common in the Eastern Mediterranean region; therefore, we conducted the first systematic review and meta-analysis on its prevalence in humans, animals, and ticks in the Eastern Mediterranean region.

METHODS

Major Iranian and international databases were searched from 2000 to 2021. We extracted the prevalence of Q fever in blood samples from animals and milk samples from animals, ticks, and humans as the main outcome. We reported the prevalence of seropositivity and molecular positivity as point estimates and 95% confidence intervals (CIs).

RESULTS

In this review, 112 papers were identified. The overall seroprevalence of Q fever was 22.4% (95% CI, 19.8 to 25.1). The pooled prevalence of Q fever in ticks was 17.5% (95% CI, -1.3 to 36.4). The prevalence was 25.5% (95% CI, 16.1 to 34.9) in humans. The prevalence of Q fever in animal blood samples from goats, sheep, camels, cattle, cats, dogs, horses, and buffalo were 28.1%, 25.1%, 25.0%, 20.1%, 9.8%, 8.4%, 6.5%, and 6.3%, respectively. Furthermore, the prevalence of Q fever in milk samples of animals was higher in cattle (20.3%) than in sheep (20.0%), goats (16.4%), and camels (3.3%).

CONCLUSIONS

Coxiella burnetii infections are common in humans and in a wide range of animal species, but they are still not recognized in many countries in the Eastern Mediterranean region, thus presenting a significant threat to human and animal health in the region.

Abstract

OBJECTIVES
Alcohol consumption is a well-established risk factor for cancer. Despite extensive research into the relationship between alcohol consumption and cancer risk, the effect of light alcohol consumption on cancer risk remains a topic of debate. To contribute to this discourse, we conducted a comprehensive systematic review and meta-analysis.

METHODS

Our systematic review aimed to investigate the associations between different levels of alcohol consumption and the risk of several cancer types. We focused on analyzing prospective associations using data from 139 cohort studies. Among them, 106 studies were included in the meta-analysis after a quantitative synthesis.

RESULTS

Our analysis did not find a significant association between light alcohol consumption and all-cause cancer risk (relative risk, 1.02; 95% confidence interval, 0.99 to 1.04), but we observed a dose-response relationship. Light alcohol consumption was significantly associated with higher risks of esophageal, colorectal, and breast cancers. Light to moderate drinking was associated with elevated risks of esophageal, colorectal, laryngeal, and breast cancers. Heavy drinking was also found to contribute to the risk of stomach, liver, pancreas, and prostate cancers, thereby increasing the risk of almost all types of cancer. Additionally, females generally had lower cancer risks compared to males.

CONCLUSIONS

Our findings highlight that cancer risks extend beyond heavy alcohol consumption to include light alcohol consumption as well. These findings suggest that there is no safe level of alcohol consumption associated with cancer risk. Our results underscore the importance of public health interventions addressing alcohol consumption to mitigate cancer risks.

본 연구는 코호트 연구를 기반으로 하여 음주의 수준에 따른 암 위험 연관성에 대해 체계적 문헌고찰(139편)과 메타분석(106편)을 수행하였다. 연구 결과, 음주와 암 위험 사이에 용량-반응 관계가 나타났으며, 소량의 음주는 암 유형에 따라 차이가 있었으나, 식도암, 대장암, 전립선암(남성), 유방암(여성)에서 암 위험과의 연관성이 있음을 발견했다. 따라서, 암 위험 측면에서 음주에 안전한 수준이 없음을 시사하며, 음주와 관련된 잠재적 피해를 완화하기 위해서는 음주 지침 강화와 같은 공중보건개입이 필요하다.

Key Message
The aim of this study was to assess the relationship between different levels of alcohol consumption and the risk of various cancer types through a systematic review and meta-analysis, providing insights into the ongoing debate about alcohol consumption and cancer causality. The findings support a dose-response relationship between alcohol consumption levels and cancer risk and the light alcohol consumption was associated with risks of esophageal, colorectal, prostate (male), and breast (female) cancer. These results emphasize the absence of a safe threshold for alcohol consumption in terms of cancer risk.

Abstract Summary PDF Supplementary Material: Abstract
OBJECTIVES
This study investigated whether the lower extremity muscle mass index (LMI) mediates the relationship between general obesity, central obesity, and knee osteoarthritis in middle-aged and elderly women in Korea.
METHODS
Data of 2,843 women aged ≥50 years were collected from the Korean National Health and Nutrition Examination Survey conducted between 2009 and 2011. General obesity and central obesity were evaluated based on body mass index (BMI) and waist circumference (WC), calculated through anthropometric measurements and body composition assessments. LMI was calculated by dividing the muscle mass in both legs—measured using the dual-energy X-ray absorptiometry—by body weight. Knee osteoarthritis was defined as a Kellgren-Lawrence scale (KL) grade of ≥2 as assessed through radiographic images.
RESULTS
Knee osteoarthritis prevalence, indicated by KL grades, was significantly higher in the general obesity and central obesity groups compared to the normal group, and conversely, lower with varying LMI levels. Using mediation analysis with bootstrapping and adjusting for covariates, we found that LMI mediated the relationship between BMI and KL (β, 0.005; 95% confidence interval [CI], 0.000 to 0.010) and WC and KL grade (β, 0.002; 95% CI, 0.001 to 0.003), explaining 4.8% and 6.7% of the total effects of BMI and WC on KL grade, respectively.
CONCLUSIONS
The study suggested that LMI partially mediates the link between general obesity and/or central obesity and knee osteoarthritis, proposing that a higher proportion of lower limb muscle mass relative to body weight can alleviate the increased risk of knee osteoarthritis caused by obesity.; Summary

Key Message
Research examining the mediating effect of lower extremity muscle mass on the relationships of knee osteoarthritis to general and central obesity is scarce. Herein, we demonstrate the mediating effect of lean mass index on the relationships of knee osteoarthritis with body mass index and waist circumference in Korean women aged 50 years or older. We propose that strengthening leg muscles may mitigate, to some extent, the risk of knee osteoarthritis associated with general and central obesity. We recommend a regimen for strengthening leg muscles through healthy lifestyle habits and regular strength training, in conjunction with weight and abdominal fat management.

Abstract

OBJECTIVES
This prospective cohort study investigated the association between blood pressure (BP) as measured in different body postures and all-cause and cardiovascular (CV) mortality risk.

METHODS

This population-based investigation included 8,901 Korean adults in 2001 and 2002. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured sequentially in the sitting, supine, and standing positions and classified into 4 categories: (1) normal, SBP <120 mmHg and DBP <80 mmHg; (2) high normal/prehypertension, SBP 120-129 mmHg and DBP <80 mmHg/SBP 130-139 mmHg or DBP 80-89 mmHg; (3) grade 1 hypertension (HTN), with SBP 140-159 mmHg or DBP 90-99 mmHg; and (4) grade 2 HTN, SBP ≥160 mmHg or DBP ≥100 mmHg. The date and cause of individual deaths were confirmed in the death record data compiled until 2013. Data were analyzed using Cox proportional hazard regression.

RESULTS

Significant associations were found between the BP categories and all-cause mortality, but only when BPs were measured in the supine position. The multivariate hazard ratios (95% confidence intervals, [CIs]) were 1.36 (95% CI, 1.06 to 1.75) and 1.59 (95% CI, 1.06 to 2.39) for grade 1 HTN and grade 2 HTN, respectively, compared with the normal category. The associations between the BP categories and CV mortality were significant regardless of body posture among participants ≥65 years, whereas they were significant for supine BP measurements only in those <65 years.

CONCLUSIONS

BP measured in the supine position predicted all-cause mortality and CV mortality better than BP measured in other postures.

Korean summary
본 역학 연구는 한국 성인 8,901명을 연구대상자로 하여 기초조사에서 세가지 자세, 즉 앉은 자세, 누운 자세, 일어선 자세에서 혈압을 측정하고, 이후 10년 동안의 사망 여부를 추적조사하여, 측정 자세에 따른 혈압과 사망 위험과의 관련성을 분석하였다. 그 결과, 누운 자세에서 측정된 고혈압(기준: 수축기 혈압이 140 mmHg 이상 혹은 이완기 혈압이 90 mmHg 이상)인 사람은 정상 혈압(기준: 수축기 혈압이 120 mmHg 미만이고 이완기 혈압이 80 mmHg 미만)인 사람에 비해 36%(1단계 고혈압) 혹은 59%(2단계 고혈압) 가량 총 사망 위험이 유의적으로 증가하는 것으로 나타났다. 이에 비해, 앉은 자세 및 일어선 자세에서 측정, 정의된 고혈압은 총 사망 위험을 증가시켰지만 유의적인 결과를 나타내지 못했다. 추후 연구에서 재확인이 필요하지만, 본 연구 결과가 시사하는 바는 앉은 자세나 일어선 자세보다 누운 자세에서 측정하는 혈압이 총 사망 위험을 더 잘 예측하므로, 고혈압 진단 외의 추가적인 활용 가능성이 있는 것으로 평가된다.

Key Message
The current epidemiological study revealed that blood pressure measured in a supine position could predict all-cause mortality and cardiovascular mortality better than blood pressure measured in a sitting or standing position. As a result, blood pressure measurements in a supine position may be useful in assessing mortality risk.

Abstract

The Korea National Disability Registration System (KNDRS) was established in 1989 to provide social welfare benefits based on predefined criteria for disability registration and an objective medical assessment using a disability grading system. Disability registration requires (1) a medical examination by a qualified specialist physician and (2) a medical advisory meeting to review the degree of disability. Medical institutions and specialists for the diagnosis of disabilities are legally stipulated, and medical records for a specified period are required to support the diagnosis. The number of disability types has gradually expanded, and 15 disability types have been legally defined. As of 2021, 2.645 million people were registered as disabled, accounting for approximately 5.1% of the total population. Among the 15 disability types, disabilities of the extremities account for the largest proportion (45.1%). Previous studies have investigated the epidemiology of disabilities using data from the KNDRS, combined predominantly with data from the National Health Insurance Research Database (NHIRD). Korea has a mandatory public health insurance system that covers the entire Korean population, and the National Health Insurance Services manages all eligibility information, including disability types and severity ratings. In short, the KNDRS-NHIRD is a significant data resource for research on the epidemiology of disabilities.

Abstract

OBJECTIVES
The coronavirus disease 2019 (COVID-19) pandemic has affected the utilization of healthcare services, including participation in cancer screening programs. We compared cancer screening participation rates for colorectal, gastric, breast, and cervical cancers among participants in the National Cancer Screening Program (NCSP) in 2019 and 2020 to address the potential distraction effect of COVID-19 on cancer screening.

METHODS

Data from the NCSP for 4 cancer types (stomach, colorectal, breast, and cervical) in 2019 and 2020 were used to calculate cancer screening participation rates by calendar month, gender, age group, and geographical region. Monthly participation rates were analyzed per 1,000 eligible individuals.

RESULTS

The screening participation rate decreased in 2020 compared to 2019 for all 4 cancers: colorectal (40.5 vs. 35.3%), gastric (61.9 vs. 54.6%), breast (63.8 vs. 55.8%), and cervical (57.8 vs. 52.2%) cancers. Following 2 major COVID-19 waves in March and December 2020, the participation rates in the 4 types of cancer screening dropped compared with those in 2019. The highest decline was observed in the elderly population aged 80 years and older (percentage change: -21% for colorectal cancer; -20% for gastric cancer; -26% for breast cancer; -20% for cervical cancer).

CONCLUSIONS

After the 2 major COVID-19 waves, the screening participation rate for 4 types of cancer declined compared with 2019. Further studies are needed to identify the indirect effects of the COVID-19 pandemic on cancer patients, such as delayed diagnoses of cancer or excess cancer deaths.

Abstract

The Korea National Health and Nutrition Examination Survey (KNHANES) is a national health survey that is conducted annually to assess the health and and health-related behaviors of Korean population. To utilize KNHANES data to studies of mortality risk factors, the Korea Disease Control and Prevention Agency (KDCA) constructed a database linking KNHANES data to cause-of-death statistics in Statistics Korea, made available to researchers since 2020. The KNHANES data were linked to the Cause of Death Statistics based on resident registration numbers for subjects aged 19 years or older who agreed to link the data. The linkage rate between 2007-2015 National Health and Nutrition Examination Survey and 2007-2019 Cause of Death Statistics was 97.1%. In the linked dataset, the total death rate was 6.6%, of which neoplasms accounted for the highest death rate (32.1%), followed by circulatory system disease (22.7%) and respiratory system disease (11.5%). The linked dataset was made available through the Research Data Center of the KDCA after a review of the research proposal, and will be made available after periodical updates.

OBJECTIVES
To test the hypothesis that tobacco exposure is associated with elevated blood pressure (EBP) in Korean adolescents, and that the association is dose dependent.
METHODS
This cross-sectional study used data from the 2011-2020 Korea National Health and Nutrition Survey (KNHANES). Subjects were eligible if they were 13-18 years at the time of participation in KNHANES. Tobacco exposure was defined by urine cotinine level. The main outcomes were EBP and hypertension. Statistical analyses were conducted using SAS version 9.4 with appropriate sampling weights to account for the complex survey design, stratification, and cluster variable.
RESULTS
A total of 2,518 adolescents was included in the analysis, representing 2.5 million Korean adolescents. The mean± standard deviation participant age was 15.3±1.7 years, and 55.3% were male. The number of participants with active tobacco smoke exposure was 283 (11.2%), passive tobacco smoke exposure was 145 (5.8%), and no smoke exposure was 2,090 (83.0%). Analysis of the 2,518 urine-cotinine-verified participants showed that tobacco smoke exposure had a significant effect on EBP: with an odds of elevated blood pressure of 3.00 (95% confidence interval [CI], 1.14 to 7.89). The odds of hypertension were 3.61 (95% CI, 1.13 to 11.49) in the active smoking group compared with the no tobacco exposure group after adjustment for potential confounders.
CONCLUSIONS
It is necessary to present a range of public health plans to reduce tobacco exposure that affects adolescents’ blood pressure, and further research with a larger number of participants using urine cotinine as a biomarker is needed.; Summary

청소년기의 고혈압은 성인기의 다양한 질병을 초래할 수 있는 주요 원인이다. 흡연과 고혈압의 관계에 관한 다수의 연구들이 있으나 상반된 결과들이 보고되었고 국내 청소년의 직 간접적 담배 연기 노출과 혈압과의 연관성은 명확하게 밝혀지지 않았다. 따라서 본 연구에서는 한국 청소년에서 담배 연기 노출과 혈압 상승과의 연관성을 확인해 보고자 하였다. 연구 결과 직접 흡연을 하는 청소년들은 비흡연군에 비하여 3배 이상 혈압이 증가하는 것으로 나타났다.

Key Message
Hypertension during adolescence is a leading cause of disease in adults. The relationship between smoking and hypertension has been studied, but findings between studies are conflicting. Nicotine is a known toxin, but the relationship between active and passive smoking and blood pressure in adolescents is not clear. So that we tested and found adolescents in Korea who were active smokers showed over 3-fold increased risk of elevated blood pressure.

Abstract Summary PDF Supplementary Material: Abstract
The coronavirus disease 2019 (COVID-19) pandemic has affected all Canadian families, with some impacted differently than others. Our study aims to: (1) determine the prevalence and transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among Canadian families, (2) identify predictors of infection susceptibility and severity of SARS-CoV-2, and (3) identify health and psychosocial impacts of the COVID-19 pandemic. This study builds upon the CHILD Cohort Study, an ongoing multi-ethnic general population prospective cohort consisting of 3,454 Canadian families with children born in Vancouver, Edmonton, Manitoba, and Toronto between 2009 and 2012. During the pandemic, CHILD households were invited to participate in the CHILD COVID-19 Add-On Study involving: (1) brief biweekly surveys about COVID-19 symptoms and testing; (2) quarterly questionnaires assessing COVID-19 exposure and testing, vaccination status, physical and mental health, and pandemic-driven life changes; and (3) in-home biological sampling kits to collect blood and stool. In total, 1,462 households (5,378 participants) consented to the CHILD COVID-19 Add-On Study: 2,803 children (mean±standard deviation [SD], 9.0±2.7 years; range, 0-17 years) and 2,576 adults (mean±SD, 43.0±6.5 years; range, 18-85 years). We will leverage the wealth of pre-pandemic CHILD data to identify risk and resilience factors for susceptibility and severity to the direct and indirect pandemic effects. Our short-term findings will inform key stakeholders and knowledge users to shape current and future pandemic responses. Additionally, this study provides a unique resource to study the long-term impacts of the pandemic as the CHILD Cohort Study continues.; Summary

Abstract

Few studies have comprehensively presented epidemiological indicators of myocardial infarction in Korea. However, multiple published articles and open-source secondary data on the epidemiology of myocardial infarction are now available. This review summarized the hospitalization incidence, prevalence, and mortality rate of myocardial infarction in Korea using articles and open-source data from the Health Insurance Service and the Department of Statistics, surveys of sample populations, registries of patients, and other sources. The epidemiological indicators of myocardial infarction were compared between Korea and other high-income countries. The incidence of hospitalization due to myocardial infarction in Korea was 43.2 cases per 100,000 population in 2016 and has consistently increased since 2011. It was 2.4 times higher among men than among women. The estimated prevalence among adults over 30 years of age ranged from 0.34% to 0.70% in 2020; it was higher among men and increased with age. The mortality in 2020, which was 19.3 per 100,000 population in 2020, remained relatively stable in recent years. Mortality was higher among men than among women. Based on representative inpatient registry data, the proportion of ST-elevated myocardial infarction decreased until recently, and the median time from symptom onset to hospital arrival was approximately 2 hours and 30 minutes. The hospitalization incidence, prevalence, and mortality rate of myocardial infarction were lower in Korea than in other countries, although there was an increasing trend. Comprehensive national-level support and surveillance systems are needed to routinely collect accurate epidemiological indicators.
