Objective To investigate the status of health literacy among urban adolescents in the Beijing-Tianjin-Hebei (BTH) region and its association with dietary behaviors, in order to provide reference for dietary education and interventions targeting adolescents in this region. Methods A stratified cluster sampling method was used to survey 6 484 middle school students in the BTH region from April to May 2023, assessing their health literacy and dietary behaviors.Chi-square tests and logistic regression analyses were employed to examine the association between health literacy and dietary behaviors. Results The proportions of urban adolescents in the Beijing-Tianjin-Hebei region with low, moderate and high health literacy levels were 24.86%, 56.92% and 18.21%, respectively, and the difference was statistically significant (χ2=2 500.332, P<0.01).The proportions of adolescents with irregular breakfast consumption, irregular meal patterns, insufficient intake of fruits and vegetables, inadequate dairy consumption, and frequent sugary drink consumption were 36.26%, 62.49%, 19.65%, 50.57%, and 54.84%, respectively.logistic regression analysis revealed that, compared to those with high health literacy, adolescents with low health literacy were more likely to exhibit poor dietary behaviors, including irregular breakfast consumption (OR=1.24), irregular meal patterns (OR=1.36), insufficient fruit and vegetable intake (OR=1.46), inadequate dairy consumption (OR=1.28), and frequent sugary drink consumption (OR=1.41) (P<0.05). Conclusions Urban adolescents in the BTH region generally have moderate health literacy, which is negatively associated with unhealthy dietary behaviors.Improving health literacy may help reduce the prevalence of poor dietary habits, thereby promoting balanced nutrition and healthy development among adolescents.
