Abstract
OBJECTIVES
To identify the distinct trajectories of sedentary behavior (SB) and explore whether reduced cardiovascular disease (CVD) risk was associated with a distinct trajectory of physical activity (PA).
METHODS
We analyzed data from 6,425 people who participated in the Korean Health Panel Survey over a period of 10 years. The participants’ self-reported SB and PA were assessed annually, and trajectory groups were identified using a group-based trajectory model for longitudinal data analysis. Logistic regression analysis was performed to assess the association between CVD risk (10-year cumulative incidence) and the trajectories of SB and PA. The adjusted variables included socio-demographic factors, the predisposing diseases of CVD, and baseline health behaviors.
RESULTS
Trajectory analysis identified 4 SB trajectory groups: SB group 1 (low and slightly increasing trend, 53.1%), SB group 2 (high and rapidly decreasing trend, 14.7%), SB group 3 (high and slightly decreasing trend, 9.9%), and SB group 4 (low and rapidly increasing trend, 22.2%). The 3 PA trajectory groups were PA group 1 (moderate and slightly decreasing trend, 32.1%), PA group 2 (low and slightly decreasing trend, 57.3%), and PA group 3 (maintained inactivity, 10.7%). By the 10-year follow-up, 577 cases of incident CVD had occurred. We also noted a 50% reduction in the risk of CVD when SB group 4 was accompanied by PA group 1 (odds ratio, 0.50; 95% confidence interval, 0.28 to 0.90).
CONCLUSIONS
Despite increased time spent in SB, maintaining PA about 2 days to 3 days per week reduced the occurrence of CVD.

Abstract
OBJECTIVES
Unexpected changes in daily routines caused by the coronavirus disease 2019 (COVID-19) pandemic may affect psychological health. This study investigated the association between various types of COVID-19-related fear and the subjective level of disturbance in daily activities experienced by individuals.
METHODS
This cross-sectional study used the Korea Community Health Survey conducted from August through November 2020. COVID-19-related fear included fear of infection, death, public criticism, family members getting infected, and economic loss. The subjective level of disruption in daily activities was measured using a 0-100 numeric rating scale developed by the Korea Disease Control and Prevention Agency. Multivariable linear regression was used to analyze the associations between the independent and dependent variables. A subgroup analysis was performed based on income level.
RESULTS
Participants who reported fear of infection (β=-3.37, p<0.001), death (β=-0.33, p=0.030), public criticism (β=-1.63, p<0.001), a family member getting infected (β=-1.03, p<0.001), and economic loss (β=-3.52, p<0.001) experienced more disturbances in daily activities. The magnitude of this association was most significant in the lowest-income group.
CONCLUSIONS
Individuals reporting COVID-19-related fear experienced higher levels of subjective disruption in daily activities.
Summary
Korean summary
이 연구는 COVID-19 팬데믹과 관련된 심리적염려가 일상생활 활동에 부정적인 영향을 줄 수 있음을 관찰하였다. COVID-19 감염으로 인한 감염, 사망, 대중의 비판, 가족 중 건강취약자의 감염, 경제적 손실에 대해 염려하는 사람은 그렇지 않은 사람에 비해 일상생활에 더 부정적인 영향을 받고 있는 것으로 관찰되었다. 특히 다양한 유형의 감염염려를 동시에 경험하고 있을수록 일상생활 지장 정도가 더 증가하는 경향이 관찰되었으며 소득수준이 낮을수록 부정적인 영향정도가 더 두드러졌다.
Key Message
Our results revealed that fear related to the COVID-19 pandemic was associated with increased levels of subjective disruptions in daily activities. Compared to individuals without fear, those with fears of COVID-19 infection, dying from infection, public criticism, a family member getting infected, and economic loss reported higher levels of disruption in daily activities. Those who reported fear of COVID-19 infection and economic loss due to infection had particularly higher levels of disturbances. Considering the various types of fear concurrently, the level of disruption experienced tended to increase with the number of reported fears.

A comprehensive study of deaths due to exposure to humidifier disinfectant in Korea: focusing on medical records, assessment of exposure to humidifier disinfectants, and causes of death

Abstract
OBJECTIVES
We aimed to determine the characteristics of the deceased victims of deaths caused by exposure to humidifier disinfectants, and present the distribution of the victims’ data submitted for damage application, demographic characteristics, imaging findings, characteristics of humidifier disinfectant exposure, and distribution of the causes of death.
METHODS
An integrated database of victims was established using the medical records data of 1,413 victims submitted during the application for death damage caused by exposure to humidifier disinfectants, and the demographic characteristics, medical records, imaging findings, exposure characteristics, and cause of death were examined.
RESULTS
The average numbers of data submissions of each applicant for death damage were 3.0 medical use records. A total of 608 (43.0%) victims had more than one finding of acute, subacute, or chronic interstitial lung diseases. The average daily and cumulative use times of the victims were 14.40 and 24,645.81 hours, respectively, indicating greater exposure in this group than in the survivors. The humidifier disinfectants’ components comprised polyhexamethylene guanidine (72.8%), chloromethylisothiazolinone/methylisothiazolinone (10.5%), other components (15.0%), and oligo-[2-(2-ethoxy)-ethoxyethyl] guanidine chloride (1.5%). The components’ distribution was 67.8% for single-component use, which was higher than that in the survivors (59.8%). The distribution of the causes of death were: respiratory diseases (54.4%), neoplasms (16.8%), and circulatory diseases (6.3%). Other interstitial lung diseases (65.5%) were the most common cause of death among those who died due to respiratory diseases.
CONCLUSIONS
Careful discussions of appropriate remedies should be conducted based on a comprehensive understanding of the characteristics of the deceased victims, considering their specificities and limitations.

가습기 살균제 사망 피해 신청자 들 중 건강피해를 인정받지 못한 신청자들이 여전히 많이 남아있으며 (약 40%), 피해판정의 복잡성과 다양한 이슈들이 산적해 있어 사망 피해 신청자들의 적정 구제를 위해 종합적인 특성파악을 바탕으로 세심한 관점에서의 검토가 필요하다. 특히, 가습기 살균제 사망 피해 신청자의 특수성과 피해구제의 제한점을 고려하여야 하며, 기계적인 건강피해 판정을 지양하고 사망 피해 신청자 중심의 세밀한 특성 파악을 바탕으로 다양한 전문가집단이 참여하는 종합적인 논의를 통해 적정구제를 이루어 나가야 함을 제안한다.
