Among a total of 6144 Korean adolescents aged 12 to 18, the participants were categorized into two groups based on their responses regarding changes in their family ES due to COVID-19: Declined ES (n = 3072) and Non-changed ES (n = 3072), with matching in terms of age, gender, and BMI. All variables were assessed using the 16<jats:sup>th<\/jats:sup> year (2020) of the Korean Youth Risk Behavior Survey. Statistical analyses were conducted using the SPSS 26.0 version, employing independent <jats:italic>t<\/jats:italic>-tests to examine anthropometrics\u2019 differences and multinominal logistic regression to predict the impact of perception of family ES on PA, SB, and stress while comparing the two groups. The significance level was set at \u03b1 = 0.05. Adolescents in the Declined ES group were 1.2 times more likely to engage in MVPA for less than 420 mins\/wk (OR = 1.16, <jats:italic>p<\/jats:italic> = 0.039), 1.7 times more likely to meet recommended muscular strength activities (i.e., \u2265 3 days\/wk) (OR = 1.70, <jats:italic>p<\/jats:italic> &lt; 0.001), 37% less likely to not meet recommended recreational sitting time (i.e., \u2265 840 mins\/wk) (OR = 0.63, <jats:italic>p<\/jats:italic> &lt; 0.01), and were 2.1 times more likely to experience very severe stress level than the Non-changed ES group (<jats:italic>p<\/jats:italic> &lt; 0.001). These results shed light on the importance of promoting mental health care in adolescents, regardless of PA levels, for their well-being during potential future pandemics. Understanding the impact of perceived ES changes on health behaviors can inform targeted interventions and support strategies to improve the mental health outcomes of adolescents during challenging times.<\/jats:p>","DOI":"10.1371\/journal.pone.0294270","type":"journal-article","created":{"date-parts":[[2023,11,13]],"date-time":"2023-11-13T18:29:21Z","timestamp":1699900161000},"page":"e0294270","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effects of COVID-19 outbreak on Korean adolescents: Impact of altered economic perception on physical activity, sedentary behavior, and stress levels in an age-, gender-, and BMI-matched study"],"prefix":"10.1371","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-7316-6031","authenticated-orcid":true,"given":"Jisu","family":"Kim","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"In-Whi","family":"Hwang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeong-Hui","family":"Park","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6134-0100","authenticated-orcid":true,"given":"Youngdeok","family":"Kim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8033-0725","authenticated-orcid":true,"given":"Jung-Min","family":"Lee","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2023,11,13]]},"reference":[{"key":"pone.0294270.ref001","doi-asserted-by":"crossref","first-page":"173644","DOI":"10.1016\/j.ejphar.2020.173644","article-title":"Treatment for COVID-19: An overview","volume":"889","author":"C Stasi","year":"2020","journal-title":"European journal of pharmacology"},{"issue":"3","key":"pone.0294270.ref002","doi-asserted-by":"crossref","first-page":"275","DOI":"10.1016\/j.shaw.2020.07.006","article-title":"Social distancing and public health guidelines at workplaces in Korea: Responses to coronavirus disease-19","volume":"11","author":"E-A Kim","year":"2020","journal-title":"Safety and Health at Work"},{"journal-title":"Mitigating the Impact of the COVID-19 Outbreak: A Review of International Measures to Support Community-Based Care.","year":"2020","author":"WD Dawson","key":"pone.0294270.ref003"},{"key":"pone.0294270.ref004","article-title":"The impact of COVID-19 on long-term care in South Korea and measures to address it.","author":"H.
