Therefore, the main aim of this study was to evaluate the association between parental health literacy levels and adolescents' physical activity and obesity in China.<\/jats:p><\/jats:sec>Methods<\/jats:title>In this cross-sectional study, a sample of 4,717 Chinese high school students and their parents participated. Parental health literacy was measured using the Chinese version of the Health Literacy Survey 2019-12-item questionnaire (HLS19-Q12), and adolescents' physical activity was assessed using the short version of the International Physical Activity Questionnaire (IPAQ). Body mass index (BMI) was calculated using standardized measurements of weight and height (kg\/m2<\/jats:sup>). Statistical analyses, including independent t-<\/jats:italic>test and multiple linear regression (to examine predictors of adolescent physical activity and BMI) were performed using SPSS 26.0 software. The significance level was set at p<\/jats:italic> &lt; 0.05.<\/jats:p><\/jats:sec>Results<\/jats:title>A total of 31.95% of adolescents were overweight or obese, and 48.15% had low physical activity, which was significantly lower in girls than in boys (p<\/jats:italic> = 0.01, Cohen's d<\/jats:italic> = 0.212). Only 21.39% of parents had excellent health literacy. Higher maternal health literacy was significantly associated with increased physical activity in boys, whereas both maternal and paternal health literacy were associated with higher physical activity in girls, with maternal health literacy showing a stronger association than paternal health literacy (p<\/jats:italic> &lt; 0.001). Furthermore, low physical activity was the only factor significantly associated with higher BMI among students (p<\/jats:italic> &lt; 0.001).<\/jats:p><\/jats:sec>Conclusion<\/jats:title>The findings highlight the importance of addressing the health literacy of parents, especially mothers, in promoting adolescent physical activity and preventing obesity. Health promotion programs and educational policies should consider family-based approaches to effectively address gender-specific needs and improve adolescent health outcomes.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fpubh.2025.1585615","type":"journal-article","created":{"date-parts":[[2025,5,19]],"date-time":"2025-05-19T05:15:33Z","timestamp":1747631733000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Maternal health literacy plays a greater role than paternal health literacy in adolescent physical activity in China: a cross-sectional study"],"prefix":"10.3389","volume":"13","author":[{"given":"Nanfang","family":"Yu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,5,19]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1383670","DOI":"10.3389\/fped.2024.1383670","article-title":"Mediation role of cardiorespiratory fitness on association of physical activity and physical literacy among 8\u201312 years old children: the PAK-IPPL cross-sectional study","volume":"12","author":"Hadier","year":"2024","journal-title":"Front Pediatr."},{"key":"B2","doi-asserted-by":"publisher","first-page":"e0312916","DOI":"10.1371\/journal.pone.0312916","article-title":"Assessing physical literacy and establishing normative reference curves for 8\u201312-year-old children from South Punjab, Pakistan: The PAK-IPPL cross-sectional study","volume":"20","author":"Hadier","year":"2025","journal-title":"PLoS ONE."},{"key":"B3","doi-asserted-by":"publisher","first-page":"373","DOI":"10.1016\/S2213-8587(21)00045-0","article-title":"Epidemiology and determinants of obesity in China","volume":"9","author":"Pan","year":"2021","journal-title":"Lancet Diabet Endocrinol."},{"key":"B4","doi-asserted-by":"publisher","first-page":"e009773","DOI":"10.1136\/bmjgh-2022-009773","article-title":"Economic impacts of overweight and obesity: current and future estimates for 161 countries","volume":"7","author":"Okunogbe","year":"2022","journal-title":"BMJ Global Health."},{"key":"B5","doi-asserted-by":"publisher","first-page":"2623","DOI":"10.3390\/nu16162623","article-title":"Prevalence and influencing factors of central obesity among adults in China: China Nutrition and Health Surveillance (2015\u20132017)","volume":"16","author":"Nan","year":"2024","journal-title":"Nutrients."},{"key":"B6","doi-asserted-by":"publisher","first-page":"102831","DOI":"10.1016\/j.pmedr.2024.102831","article-title":"Prevalence of overweight\/obesity, and associated factors among adolescents aged 12\u201315 in Shandong Province, China: a cross-sectional study","volume":"45","author":"Huang","year":"2024","journal-title":"Prevent Med Rep."},{"key":"B7","doi-asserted-by":"publisher","first-page":"58","DOI":"10.1186\/s12913-023-10510-x","article-title":"Key factors affecting health promoting behaviors among adolescents: a scoping review","volume":"24","author":"Tabrizi","year":"2024","journal-title":"BMC Health Serv Res."},{"key":"B8","doi-asserted-by":"publisher","first-page":"188","DOI":"10.1186\/s13690-023-01197-x","article-title":"Influence of adolescents' and parental dietary knowledge on adolescents' body mass index (BMI), overweight\/obesity in 2004\u20132015: a longitudinal study","volume":"81","author":"Cai","year":"2023","journal-title":"Arch Public Health."},{"key":"B9","doi-asserted-by":"publisher","first-page":"3717","DOI":"10.3390\/nu13113717","article-title":"How does the family influence adolescent eating habits in terms of knowledge, attitudes and practices?
