Abstract
OBJECTIVES
This study aimed to investigate changes in health behaviors, including cigarette smoking, alcohol drinking, physical activity, dietary behaviors, and obesity, before and during the coronavirus disease 2019 (COVID-19) pandemic using the Korea Youth Risk Behavior Survey (KYRBS) database.
METHODS
KYRBS data from 2015 to 2021 were used in this study. Differences in health behaviors between before (pre-pandemic period: 2018-2019) and during (pandemic period: 2020-2021) the pandemic were examined. Differences were compared using linear regression and the chi-square test considering the complex survey design after adjusting for grade level.
RESULTS
The prevalence of current cigarette smoking and current alcohol drinking significantly decreased in both male and female students during the pandemic compared to the pre-pandemic period. However, the prevalence of obesity significantly increased in both male and female students during the same period. When examining physical activity and dietary behaviors closely related to obesity, fast food consumption increased and fruit consumption decreased during the pandemic in both male and female students, whereas no significant changes in physical activity were observed in either male or female students.
CONCLUSIONS
The deterioration of adolescent dietary behaviors and an increase in the prevalence of obesity can increase the future disease burden, and concerted efforts at the individual and national levels are needed to reduce obesity and promote healthy dietary behaviors.
Summary
Korean summary
이 연구는 한국 청소년건강행태조사자료(KYRBS)를 사용하여 코로나19 유행 전후의 우리나라 청소년들의 흡연, 음주, 신체활동, 식습관, 비만 등의 건강행태의 변화에 대하여 살펴보고자 하였다. 이 연구에서는 2015년부터 2021년까지의 청소년건강행태조사자료를 사용하여, 코로나19 유행 이전 (2018-2019년)과 코로나 유행 이후 (2020-2021년) 기간의 건강행태의 변화에 대하여 조사하였다. 학년레벨을 보정한 후, 복합표본설계를 고려하여 로지스틱 회귀분석과 카이제곱검정을 이용하여 코로나19 유행 이전 (2018-2019년)과 비교하여, 코로나 유행 이후 (2020-2021년) 기간의 건강행태의 변화가 있었는지에 대하여 확인하였다. 그 결과, 코로나19 유행 이전 (2018-2019년)과 비교하여, 코로나19 유행 기간(2020-2021년) 동안에 현재흡연율과 현재음주율이 유의하게 감소하였다. 그러나 동일한 기간 동안에 남학생과 여학생 모두에서 비만율이 유의하게 증가하였는데, 비만율과 관련된 신체활동 및 식습관에 대하여 살펴보았을 때, 신체활동에서는 유의한 변화가 없었던 반면, 남학생과 여학생 모두에서 패스트푸드 섭취는 증가하고 과일섭취가 감소한 것으로 나타났다. 따라서 코로나19 유행기간 동안 흡연율 및 음주율 등의 청소년 건강에 유익한 변화도 있었으나, 비만율도 같이 증가한 것을 확인할 수 있었다. 청소년기의 식습관의 악화 및 비만율의 증가는 미래 우리나라의 질병부담을 증가시킬 수 있기 때문에, 청소년의 비만율을 낮추고 건강한 식습관을 증진시키기 위한 개인 및 사회 차원의 노력이 필요하다.
Key Message
-The current cigarette smoking and current alcohol drinking rates significantly decreased among Korean adolescents during the pandemic period compared to the pre-pandemic period. -On the other hand, the obesity rate increased significantly especially among Korean male adolescents, which is accompanied by changes in dietary habits such as an increase in fast food intake and a decrease in fruit intake.

Abstract
OBJECTIVES
We aimed to examine the current status and trends of food and nutrient intake in the Korean population over the past 20 years using the data from the Korea National Health and Nutrition Examination Survey (KNHANES).
METHODS
We conducted a survey of 116,284 subjects over the age of one year in Korea, who participated in the KNHANES between 1998 and 2018. We collected data on the subjects’ intake for the day before using the 24-hour recall method. The annual percent change (APC) in the food groups and nutrient intake were calculated using SAS and Joinpoint software.
RESULTS
The intake of grains (APC=-0.4, p<0.05) and vegetables (APC=-0.8, p<0.05) was observed to decrease. In contrast, the intake of beverages, meat, dairy, and eggs increased. In particular, beverage intake increased by more than four times (APC=9.2, p<0.05). There was no significant change in energy intake. However, the proportion of energy intake from carbohydrates decreased by approximately 5%p (APC=-0.3, p<0.05), whereas that from fat increased by approximately 5%p (APC= 1.1, p<0.05). Additionally, there were decreases in the proportion of energy intake from breakfast and homemade meals and increases in the energy intake from snacks, dining out, and convenience food. The intake of vitamin C (APC=-3.2, p<0.05) and sodium (APC=-2.3, p<0.05) significantly decreased.
CONCLUSIONS
Over the past 20 years, there has been decreases in the intake of grains, vegetables, carbohydrates, sodium, and vitamin C and increases in the intake of beverages, dairy, meat, eggs, and fat. Since nutritional status is an important factor in the prevention and management of chronic diseases, it should be continuously monitored.
