BACKGROUND In addition to medication, health behavior management is crucial in patients with multiple risks of cardiovascular mortality. OBJECTIVE This study aimed to examine the efficacy of a 3-month Smart Management Strategy for Health–based electronic program (Smart Healthing). METHODS A 2-arm randomized controlled trial was conducted to assess the efficacy of Smart Healthing in 106 patients with at least one indicator of poor disease control and who had hypertension, diabetes, or hypercholesterolemia. The intervention group (n=53) took part in the electronic program, which was available in the form of a mobile app and a Web-based PC application. The program covered 4 areas: self-assessment, self-planning, self-learning, and self-monitoring by automatic feedback. The control group (n=53) received basic educational material concerning disease control. The primary outcome was the percentage of participants who achieved their clinical indicator goal after 12 weeks into the program: glycated hemoglobin (HbA<sub>1c</sub>) <7.0%, systolic blood pressure (SBP) <140 mmHg, or low-density lipoprotein cholesterol <130 mg/dL. RESULTS The intervention group showed a significantly higher success rate (in comparison with the control group) for achieving each of 3 clinical indicators at the targeted goal levels (<italic>P</italic><.05). Only the patients with hypertension showed a significant improvement in SBP from the baseline as compared with the control group (72.7% vs 35.7%; <italic>P</italic><.05). There was a significant reduction in HbA<sub>1c</sub> in the intervention group compared with the control group (difference=0.54%; <italic>P</italic>≤.05). In the intervention group, 20% of patients with diabetes exhibited a ≥1% decrease in HbA<sub>1c</sub> (vs 0% among controls; <italic>P</italic>≤.05). CONCLUSIONS A short-term self-management strategy-based electronic program intervention may improve clinical outcomes among patients with cardiovascular risks.

Objective: During the outbreak of COVID-19,several coping strategies were implemented including strengthened social distancing, wearing masks and hand hygiene. Thisinfection control method might have been effective for other respiratory infections; however, it had not yet been clearly revealed. Therefore,we investigatedwhetherthe incidence of infectious respiratory diseases has reduced after excluding the effect of decreased medical utilization because of COVID-19 control measures.Design or methods: We used the Korean national claims data and analyzed incidences of acute respiratory infections (ARI) and diseases except ARI. The incidence rates of winter 2019 and 2020 were compared.Results: Excluding ARI,the reduction in overall hospital visits decreased by only 2%; however,the number of visits due to ARI decreased by 13%, and the number of visits due to influenza particularly decreased by 26%.Conclusions: Using national database, this study confirmed that a significant reduction in ARI, including influenza, occurred during the COVID-19 pandemic. Infection control measures including nationally enforced social distancing may be effective in controlling the transmission of other respiratory infections. Further studies are necessary to clarify the causal relationship.
Abstract Most persons with confirmed coronavirus disease (COVID-19) have no or mild symptoms. During the COVID-19 pandemic, communities need efficient methods to monitor asymptomatic patients to reduce transmission. We describe the structure and operating protocols of a community treatment center (CTC) run by Seoul National University Hospital (SNUH) in South Korea. SNUH converted an existing facility into a CTC to isolate patients who had confirmed COVID-19 but mild or no symptoms. Patients reported self-measured vital signs and symptoms twice a day by using a smartphone application. Medical staff in a remote monitoring center at SNUH reviewed patient vital signs and provided video consultation to patients twice daily. The CTC required few medical staff to perform medical tests, monitor patients, and respond to emergencies. During March 5–26, 2020, we admitted and treated 113 patients at this center. CTCs could be an alternative to hospital admission for isolating patients and preventing community transmission.
This study aims to evaluate the psychometric properties of the Satisfaction with Life Scale (SWLS) and the Subjective Well-Being Inventory (SWBI) in a nationally representative sample in Korea. A total of 1200 people completed the semi-structured, self-reported questionnaire, which included five items from the SWLS and 14 items from the SWBI. All items and the total score of both the SWLS and the SWBI showed high internal consistency (with Cronbach’s alphas of 0.886 and 0.946, respectively). The item-total correlation values for both measures were in the ranges of 0.71–0.75 and 0.65–0.80, respectively. There were positive correlations between the SWLS and SWBI (r = 0.59, p = 0.01). The SWLS, SWBI and global well-being (GWB) scores were positively correlated with the McGill Quality of Life subscales (p = 0.01) but negatively correlated with the Patient Health Questionnaire-9 (p = 0.01). Participants under 50 years old (adjusted odds ratio [aOR] = 1.30, 95% confidence interval [CI] = 1.00–1.69) and those in rural areas (aOR = 1.63, 95% CI = 1.28–2.07) had higher scores on the SWLS than other participant groups. Participants who were under 50 years old (aOR = 1.47, 95% CI = 1.12–1.92), were male (aOR = 1.33, 95% CI = 1.04–1.71), were married (aOR = 1.51, 95% CI = 1.13–2.01), lived in rural areas (aOR = 2.30, 95% CI = 1.35–3.91), or had higher incomes (aOR = 1.30, 95% CI = 1.02–1.65) showed higher SWBI scores. This study showed that the SLWS and SWBI have good psychometric properties and could be applicable to Korea.
Background/Aims As the novel coronavirus (coronavirus disease 2019 [COVID-19]) outbreak progresses rapidly, staying home is recommended for suspected patients; however, the safety of this recommendation is uncertain. In Korea, non-hospital facilities called "living and treatment centers (LTCs)" have been established since 5 March 2020. The LTCs provided a unique opportunity to evaluate the safety of selection criteria for low-risk groups. Methods Between 5 March and 9 April 2020, patients with COVID-19 who met the following criteria were admitted to the LTC; alert, age below 65 years old, no underlying disease or well-controlled underlying disease, body temperature below 38.0°C, whether taking antipyretics or not, and no dyspnea. Patients were closely observed by doctors or nurses' interviews twice a day and transferred to hospitals when symptoms worsened. Results A total of 113 patients were admitted to the LTC; 52.2% were female, with a median age of 25 years (interquartile range, 21.5 to 39.5). Of 113 patients, 54 (47.8%) were asymptomatic at diagnosis, and 15 (13.3%) had no symptoms until they were released from isolation. During the follow-up period, two (1.8%) patients were transferred to a hospital but did not progress to severe status during hospitalization. Conclusions The risk of progression was negligible in COVID-19 patients who met the admission criteria for LTC at the time of diagnosis. LTCs could be a safe alternative considering shortage of hospital beds.
This study aimed to report the overall national trends in the rates of cancer screening based on recommendations and provide insights into the changing trends of these rates across different demographics. Materials and MethodsThis study used data from the Korean National Cancer Screening Survey (KNCSS), which surveys nationwide cancer-screening rates and includes 4,500 individuals meeting the Korean National Cancer Screening Program (NCSP) protocol age criteria.Cancer-screening rates were assessed using structured questionnaires; yearly trends were analyzed for both lifetime cancerscreening rates and rates of screening based on recommendations, and subgroup analyses were performed based on age and sex.
Abstract Background Thyroid cancer overdiagnosis is a major public health issue in South Korea, which has the highest incidence rate. The accessibility of information through the Internet, particularly on YouTube, could potentially impact excessive screening. This study aimed to analyze the content of thyroid cancer-related YouTube videos, particularly those from 2016 onwards, to evaluate the potential spread of misinformation. Methods A total of 326 videos for analysis were collected using a video search protocol with the keyword “thyroid cancer” on YouTube. This study classified the selected YouTube videos as either provided by medical professionals or not and used topic clustering with LDA (latent dirichlet allocation), sentiment analysis with KoBERT (Korean bidirectional encoder representations from transformers), and reliability evaluation to analyze the content. The proportion of mentions of poor prognosis for thyroid cancer and the categorization of advertising content was also analyzed. Results Videos by medical professionals were categorized into 7 topics, with “Thyroid cancer is not a ‘Good cancer’” being the most common. The number of videos opposing excessive thyroid cancer screening decreased gradually yearly. Videos advocating screening received more favorable comments from viewers than videos opposing excessive thyroid cancer screening. Patient experience videos were categorized into 6 topics, with the “Treatment process and after-treatment” being the most common. Conclusion This study found that a significant proportion of videos uploaded by medical professionals on thyroid cancer endorse the practice, potentially leading to excessive treatments. The study highlights the need for medical professionals to provide high-quality and unbiased information on social media platforms to prevent the spread of medical misinformation and the need for criteria to judge the content and quality of online health information.
BACKGROUND/OBJECTIVES: Numerous school-based weight control programs have been initiated for weight loss among adolescents.However, the relationship between these programs and inappropriate weight control efforts, dietary habits and behavior of students, have not been investigated sufficiently.This study was undertaken to investigate the association between body mass index (BMI) of adolescents, and their health status and inappropriate weight-control efforts.We further examined the relationship between attendance to school-based weight-control programs and attempting inappropriate weightcontrol efforts, dietary habits, and behavior.SUBJECTS/METHODS: A survey of 1,742 students was conducted in Korea.Logistic regression was used to assess differences in the health status (grouped by BMI and improper weight control) and dietary habits, based on attendance to the weight-control programs.RESULTS: Obese students were significantly more dissatisfied with physical, mental and spiritual health.Students who attended weight-control programs were likely to be underweight (P < 0.001), whereas those who did not attend weight-control programs were likely to attempt weight control improperly (P < 0.001).Students who participated in the program also had relatively healthy dietary habits (P < 0.001-0.027),and students who did not attend had comparatively unhealthy dietary habits (P < 0.001-0.008).Students who attended weight-control programs were likely to be underweight (P < 0.001) with relatively healthy dietary habits (P < 0.001-0.027),whereas students who did not attend the programs were likely to attempt weight control improperly (P < 0.001) and had comparatively unhealthy dietary habits (P < 0.001-0.008).CONCLUSIONS: Attending school-based weight-control programs was significantly associated with not attempting inappropriate weight-control efforts, as well as following healthy dietary habits.Our data indicates that offering school-based weight-control programs is valuable to student health, and is anticipated to reducing the public health burden.
BACKGROUND The COVID-19 pandemic has radically shifted living practices, thereby influencing changes in the health status and behaviors of every person. OBJECTIVE The aim of this study was to investigate the impact of COVID-19 on the self-reported health status and health behaviors along with any associated factors in adults in the Republic of Korea wherein no stringent lockdown measures were implemented during the pandemic. METHODS We conducted a web-based self-reported survey from November 2020 to December 2020. The study participants (N=2097) were identified through quota sampling by age, sex, and geographical regions among residents aged 19 years or older in Korea. The survey collected information on basic demographics, changes in self-reported health status, and health behaviors during the COVID-19 pandemic. Self-reported health status and health behaviors were categorized into 3 groups: unchanged, improved, or worsened. A chi-square test and logistic regression analyses were conducted. RESULTS With regard to changes in the self-reported health status, the majority (1478/2097, 70.5%) of the participants reported that their health was unchanged, while 20% (420/2097) of the participants reported having worser health after the COVID-19 outbreak. With regard to changes in health behaviors, the proportion of participants who increased tobacco consumption was similar to that of those who decreased tobacco consumption (110/545, 20.2% vs 106/545, 19.5%, respectively), while the proportion of those who decreased their drinking frequency was more than twice as many as those who increased their drinking frequency (578/1603, 36.1% vs 270/1603, 16.8%, respectively). Further, those who decreased their exercising frequency were more than those who increased their exercising frequency (333/823, 15.9% vs 211/823, 10%, respectively). The factor that had the greatest influence on lifestyle was age. In the subgroup analysis, the group aged 20-29 years had the highest number of individuals with both a worsened (100/377, 26.5%) and an improved (218/377, 15.7%) health status. Further, individuals aged 20-29 years had greater odds of increased smoking (6.44, 95% CI 2.15-19.32), increased alcohol use (4.64, 95% CI 2.60-8.28), and decreased moderate or higher intensity aerobic exercise (3.39, 95% CI 1.82-6.33) compared to individuals aged 60 years and older. Younger adults showed deteriorated health behaviors, while older adults showed improved health behaviors. CONCLUSIONS The health status and the behavior of the majority of the Koreans were not found to be heavily affected by the COVID-19 outbreak. However, in some cases, changes in health status or health behavior were identified. This study highlighted that some groups were overwhelmingly affected by COVID-19 compared to others. Certain groups reported experiencing both worsening and improving health, while other groups reported unchanged health status. Age was the most influential factor for behavior change; in particular, the younger generation’s negative health behaviors need more attention in terms of public health. As COVID-19 prolongs, public health interventions for vulnerable groups may be needed.
