Abstract
OBJECTIVES
This study aimed to analyze the changes in chronic disease management indicators, including hypertension, diabetes mellitus, and hypercholesteremia, from 2010–2020 and before (2019) and during (2020) the coronavirus disease 2019 (COVID-19) pandemic.
METHODS
This study included 58,504 individuals aged ≥30 years who participated in the Korea National Health and Nutrition Examination Survey 2010–2020. Trends in the prevalence of chronic diseases and awareness, treatment, and control in persons treated for chronic diseases and the difference in those between before and during the COVID-19 pandemic were analyzed using the SAS program PROC SURVEYREG.
RESULTS
From 2010–2020, the awareness, treatment, and control in adults aged ≥30 years for hypertension and hypercholesterolemia continuously improved, whereas no significant change in the management indicators of diabetes mellitus was observed. The prevalence of hypertension, diabetes mellitus, and hypercholesterolemia in men increased from before to during the COVID-19 pandemic. However, there was no significant change in the management indicators of hypertension and diabetes mellitus in men and women, and the awareness, treatment, and control rates for hypercholesterolemia increased by 5.5%, 6.9%, and 4.1%, respectively.
CONCLUSIONS
In 2020, the first year of the COVID-19 pandemic, the prevalence of hypertension, diabetes mellitus, and hypercholesterolemia increased, but the management indicators of the chronic diseases did not significantly deteriorate. Considering the ongoing COVID-19 pandemic, it is necessary to monitor changes in chronic disease management indicators and to develop efficient and accessible chronic disease prevention and management programs.

Abstract
Objectives
This study was to examine the changes in dietary habits and food and nutrient intakes between before (2019) and during (2020) the coronavirus disease 2019 (COVID-19) pandemic from the Korea National Health and Nutrition Examination Survey (KNHANES).
Methods
A total of 54,995 participants aged ≥19 years who participated in the 2011-2020 KNHANES were included. The 10-year trend (2011-2020) and differences between 2019 and 2020 for dietary habits and food and nutrient intakes were estimated using SAS.
Results
In the past 10 years (2011–2020), the dietary habits (increase in skipping meals and eating out), food intake (increase in meats and decrease in fruits and vegetables), and nutrient intake (increase in fat and decrease in sodium) in adults have changed. When comparing between 2019 and 2020, there were 4.6%p decrease in the eating out more than once a day. On the other hand, there were no significant differences in the intakes of food, energy and most of nutrients between 2019 and 2020, except for the proportion of energy intake from fat (1%p increase) and carbohydrate (1%p decrease).
Conclusions
Although a change in dietary habits from before to during the COVID-19 pandemic was observed, food and nutrient intakes have not deteriorated markedly and appear similar to the trends in the past 10 years. Throughout the COVID-19 pandemic, it is necessary to monitor the effects of changes in dietary habits on health as well as food and nutrient intakes.

Abstract
The Korea National Health and Nutrition Examination Survey (KNHANES) was initiated in 1998 to provide evidence for the development and evaluation of health policies and programs. The Korea Disease Control and Prevention Agency is responsible for the KNHANES and has conducted it as a series of surveys. Over the past 20 years, efforts to produce accurate, timely, and nationwide health statistics have been refined by establishing a continuous annual survey system with full-time field staff, incrementally expanding survey components, collaborating with relevant academic societies for quality control, and revising the survey methods. Additionally, the utility of the collected data was increased by linking the KNHANES data with related data from other government agencies or institutions and making the overall data publicly available on the official website of KNHANES (https://knhanes.kdca.go.kr). Additional long-term plans are being developed, including plans to continue producing nationwide health indicators and invigorating the utilization of the KNHANES data.

Key Message
The Korea National Health and Nutrition Examination Survey (KNHANES) is an ongoing surveillance system that was initiated in 1998 based on Ar¬ticle 16 of the National Health Promotion Act to produce nationwide statistics regarding the health status, health behaviors, and food and nutrient consumption of the Korean population. In this study, the 20-year accomplishments of the KNHANES including vigorous production of health indicators and improvement of data utilization are summarized, and future plans are presented to improve the health statistics to reflect changes in the social and survey environments.

Abstract
PURPOSE
The purpose of this study is to review the process for establishing a pediatric communicable diseases sentinel surveillance system, and the results of operation based on the accumulated data to understand the descriptive epidemiologic characteristics of pediatric communicable diseases.
METHODS
A sentinel surveillance system for pediatric communicable diseases was developed in May 2001 with the 202 doctors in pediatric clinics who participated voluntarily. The target diseases for sentinel surveillance were measles, mumps, rubella, chicken pox and aseptic meningitis. The case definitions of those diseases for surveillance were divided into confirmed cases and suspected cases by the diseases definitions of national notifiable diseases system. The participants should report as soon as possible when they diagnosed measles, mumps, rubella cases including suspected ones. But chicken pox and aseptic meningitis cases were reported once a week in regular base including zero report. We collected the data from May 2001 to December 2003 and showed the descriptive epidemiologic characteristics of each disease.
RESULTS
The average reporting proportion among survellance doctors has been increased, about 88% in 2003. For measles, 206 cases were reported in 2001, 10 cases in 2002, and 2 cases in 2003. Children under the age of 2 (53.4 %) showed the highest. Among the measles cases, 86.4% had no previous vaccination history. In case of mumps, 246 cases in 2001, 241 in 2002, and 566 cases in 2003 were reported. Mumps showed seasonality, highest from April to June in each year. The sex ratio was about 1.5(M:F = 6:4). Among the reported cases, 76.9 % had previous MMR immunization history at least one time. For Rubella, 9 cases in 2001, 3 in 2002, and no case were reported in 2003. The chicken pox case proportion per 100 pediatric consultations showed peak in from May to June and from November to January. 3-5 year-old children (45.7%) were showed high proportion by age.
CONCLUSION
This study described the process of establishing and operating a system for the pediatric communicable disease sentinel surveillance. We analyzed the desriptive epidemiologic characteristic of the reported data from May 2001 to December 2003. These data maybe useful to build the policy of public health management for communicable diseases control system and vaccine preventable diseases.
