This study determined the relationships of functional, interactive and critical adolescent health literacy with sociodemographic characteristics, social media exposure (SME), and perceived health status (PHS). A total of 314 high school students from Grades 7 to 10 completed a self-administered questionnaire. Findings revealed that functional health literacy is influenced by age (p-value = 0.058) and parents' educational attainment (FEA: p-value = 0.059; MEA: p-value = 0.033); interactive health literacy was only significantly associated with SME (p-value = 0.004); and critical health literacy was significantly correlated with father's educational attainment (p-value = 0.062), SME (p-value = 0.08), and PHS (p-value = 0.019). For the logistic regression model of functional health literacy, only age was a distinct variable, and for interactive health literacy, it was SME. Other variables such as parenting styles, socioeconomic class, and school and peer influences are encouraged for future research for a deeper understanding of adolescent health literacy.
