Abstract
OBJECTIVES
To efficiently utilize limited health and medical resources, it is necessary to accurately measure the level of health, which requires estimating the multimorbidity-corrected burden of disease.
METHODS
This study used 2015 and 2016 data from the National Health Insurance Service, and employed the list of diseases defined in a Korean study of the burden of disease, the criteria for prevalence, and the “cause–sequelae–health state” disease system. When calculating the years lost to disability (YLD), multimorbidity was corrected using Monte-Carlo simulation.
RESULTS
Correcting for multimorbidity changed YLD at all ages in Korea by -1.2% (95% confidence interval [CI], -24.1 to 3.6) in males and -12.4% (95% CI, -23.0 to 0.3) in females in 2015, and by -10.8% (95% CI, -24.1 to 4.6) in males and -11.1% (95% CI, -22.8 to 1.7) in females in 2016. The YLD rate for non-communicable diseases in males decreased more than that of other disease groups in both years, by -11.8% (95% CI, -19.5 to 3.6) and -11.5% (95% CI, -19.3 to -3.0), respectively. The overall YLD rate changed by -1.3% in the 5-year to 9-year age group, and the magnitude of this change remained similar until the 10-19-year age group, gradually decreased after 20 years of age, and steeply increased to more than 10% in those aged 60 and older.
CONCLUSIONS
Calculations of YLD should adjust for multimorbidity, as the disease burden can otherwise be overestimated for the elderly, who tend to exhibit a high prevalence of multimorbidity.

Abstract
Objectives
To assess the social inequalities in changes of dietary behaviors among adolescents during the COVID-19 pandemic, we compared changes in dietary behavior indicators by household income.
Methods
Using cross-sectional data from the 2019 and 2020 Korea National Health and Nutrition Examination Survey, the prevalence of dietary behaviors in adolescents (12-18 years old) was estimated and changes in dietary behaviors before and after the COVID-19 pandemic were evaluated. We assessed changes in dietary behaviors with a household income (as a measure of socioeconomic status [SES]) disparity.
Results
During the COVID-19 pandemic, average consumption of vegetables has decreased and food insecurity has worsened. Adolescents were more likely to skip breakfast than before COVID-19 (33.1 % and 37.4 %). Soft drink consumption also increased in 2020 than in 2019 (7.6 % and 14.8 %), especially among boys. Average sugar intake and sodium intake showed a tendency to decrease only in girls, but there was no difference according to SES level. Skip breakfast was particularly evident in the low SES group, and the difference according to household income level (high vs. low) was greater after COVID-19 than before. The prevalence of soft drink consumption increased significantly in low SES group, but the rate of increase did not differ by SES level.
Conclusions
We found that the social disparity in skipping breakfast was further aggravated. For a better understanding of the dietary behaviors of adolescents, continuous monitoring is necessary.
