The study evaluated the association between exposure to antidepressants or central nervous system (CNS) stimulants and the likelihood of meeting the Centers for Disease Control and Prevention (CDC) physical activity guidelines (\u226560 min of moderate-to-vigorous physical activity daily) among U.S. children. Methods: We used data from the 2017\u2013March 2020 National Health and Nutrition Examination Survey (NHANES) to quantify medication use and physical activity duration. The exposure to antidepressants and CNS stimulants in children and their level of physical activity were captured via interviews with pediatric participants and their adult proxies. The proportion of children meeting the CDC-recommended physical activity level was compared between propensity-score-matched antidepressant users vs. non-users, as well as matched CNS-stimulant users and non-users, using Rao\u2013Scott chi-square tests. Results: Among 3835 NHANES participants aged 2\u201317 years, representing approximately 59.4 million U.S. children, 0.89% used antidepressants, and 2.40% used CNS stimulants. After accounting for age, sex, race\/ethnicity, body mass index (BMI), and family income, a smaller proportion of CNS stimulant users met physical activity guidelines compared with non-users (22.06% vs. 37.02%; p = 0.0075). Antidepressant use was not significantly associated with physical activity level (12.06% vs. 15.52%; p = 0.6342). Conclusions: These findings highlight the importance of monitoring activity patterns among youth prescribed CNS stimulants and antidepressants, particularly integrating physical activity promotion into public health strategies.<\/jats:p>","DOI":"10.3390\/children13070914","type":"journal-article","created":{"date-parts":[[2026,7,10]],"date-time":"2026-07-10T14:14:25Z","timestamp":1783692865000},"page":"914","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Central Nervous System Stimulants, but Not Antidepressants, Are Associated with Lower Physical Activity in U.S. Youth: NHANES 2017\u2013March 2020"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-3060-7179","authenticated-orcid":false,"given":"Bowen","family":"Ma","sequence":"first","affiliation":[{"name":"School of Natural Sciences, Rice University, Houston, TX 77005, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7889-8023","authenticated-orcid":false,"given":"Hua","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Health Outcomes and Policy, College of Pharmacy, University of Houston, Houston, TX 77204, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2009","DOI":"10.1001\/jama.2018.5690","article-title":"Trends in Prescription Medication Use Among Children and Adolescents\u2014United States, 1999\u20132014","volume":"319","author":"Hales","year":"2018","journal-title":"JAMA"},{"key":"ref_2","unstructured":"Martin, C.B., Hales, C.M., Gu, Q., and Ogden, C.L.
