  This study aims to develop in-depth questionnaires for the Korea Youth Risk Behavior Survey in the areas of dietary behavior, physical activity, obesity, and weight control, to better understand the health behaviors of adolescents and explore the modifying factors. Apropos this, current and emerging issues regarding adolescent health were identified through a literature review and analysis of the past survey results. The questionnaire was developed not only to understand the health behaviors of adolescents, but also to identify factors affecting the health behaviors of adolescents. The final questionnaire was developed after taking into account the results of surveys to assess students’ understanding of the questionnaire, another survey to evaluate the reliability of the questionnaire, and experts’ opinion on the developed questionnaire. Finally, 44 items on 21 topics were developed for an in-depth survey on dietary behavior, physical activity, obesity, and weight control. Through priority evaluation, the following items were selected for the 2022 Korea Youth Risk Behavior Survey: “high rate of soda · sugar drinks intake,” “high rate of delivery food and night snack intake,” “high rate of high caffeine drink intake,” “deterioration of lifestyle habits,” “small amount of physical activity,” “intervention factors for physical activity,” and “increase in monthly inappropriate weight control attempts among those attempting to lose weight.” These questionnaires will generate important evidence to understand adolescents’ health behaviors and develop a public health strategy to improve them.

  We aimed to identify the severity of the Coronavirus disease 2019 specifically according to the SARS-CoV-2 variant in the Republic of Korea by describing the number of severe/critical cases and deaths, case severity rate (CSR) and case fatality rate (CFR). A total of 23,496,849 confirmed cases were reported during January 20, 2020 to September 3 , 2 022. 2 6,472 (0.11%) cases were considered severe/critical and 27,471 (0.12%) resulted in death. The omicron BA.1/BA.2 period showed most severe/critical cases and deaths accounting for 40.7% (10,772 patients) and 66.4% (18,252 patients), respectively. In the omicron variant dominant period, the proportion of the age 80 and over saw on increase in severe/critical cases and deaths by 26.4%p, 7.4%p, respectively, than those in the delta dominant period. The CSR and CFR were 0.20% and 0.12% over that period. The CSR decreased from 2.98% in the pre-delta dominant period to 2.14% in the delta dominant period, and 0.14% in the omicron BA.1/BA.2 period. CFR was also highest at 1.15% in the pre-delta dominant period and decreased to 0.95% in the delta dominant period, 0.10% in the omicron BA.1/BA.2 period. Despite the increase in severity of the delta variant, overall severity decreased in the delta dominant period showing continuous decrease in the omicron dominant period. In the omicron dominant period, the proportion of the elderly of severe/critical and fatal condition increased which suggests the importance of focusing on the response strategy of the elderly.
