Methods: We collected survey data from 28,514 elementary school students participating in the 2023 Student Health Examination conducted by the Korea Ministry of Education. PA participation was the independent variable, defined as whether elementary school students participate in exercise that makes them out of breath or sweat more than three times a week. The variables related to lifestyle habits included breakfast intake, amount of sleep, TV viewing, gaming\/Internet use, thoughts about running away from home, perceived body image, and body mass index. The variables for school life included experiences of being bullied, the need for counseling regarding school life problems, and the need for counseling for distress. The collected data were analyzed using frequency analysis, chi-squared tests, and multivariate logistic regression analyses. Results: PA was significantly associated with regular breakfast intake, sufficient sleep, limited television viewing, reduced gaming\/Internet use, and a positive perception of body image. Specifically, regarding breakfast intake, the average odds ratio (OR) was 1.160 for always having it. Regarding the amount of sleep, the average OR was 0.836 for less than 6 h, 0.692 for 6\u20137 h, and 0.767 for 7\u20138 h. Regarding TV viewing, the average OR was 0.831 for yes. For gaming, the average OR was 0.770 for yes. Regarding perceived body image, the average OR was 1.429 for slightly thin, 1.487 for normal, and 1.400 for slightly fat. Conclusions: These results suggest that children\u2019s PA facilitates the formation of good lifestyle habits; therefore, it should be actively encouraged in children.<\/jats:p>","DOI":"10.3390\/children12050570","type":"journal-article","created":{"date-parts":[[2025,5,1]],"date-time":"2025-05-01T03:50:43Z","timestamp":1746071443000},"page":"570","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Effect of Physical Activity Participation on Lifestyle Habits and School Life Among Korean Children"],"prefix":"10.3390","volume":"12","author":[{"given":"Seungok","family":"An","sequence":"first","affiliation":[{"name":"Department of Special Physical Education, Yongin University, Yongin 17092, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Su-Yeon","family":"Roh","sequence":"additional","affiliation":[{"name":"Department of Exercise Rehabilitation, Gachon University, Incheon 21936, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-9571-1501","authenticated-orcid":false,"given":"Jeonga","family":"Kwon","sequence":"additional","affiliation":[{"name":"Department of Elementary Education, College of First, Korea National University of Education, Cheongju 28173, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2423","DOI":"10.1016\/S0140-6736(16)00579-1","article-title":"Our future: A Lancet commission on adolescent health and wellbeing","volume":"387","author":"Patton","year":"2016","journal-title":"Lancet"},{"key":"ref_2","first-page":"99","article-title":"Concept and methodology of the Health Behaviour in School-aged Children (HBSC) study\u2013Insights into the current 2022 survey and trends in Germany","volume":"9","author":"Winter","year":"2024","journal-title":"J.
