Health Literacy and Smoking Habits Among a Sample of Jordanian University Students

Limited health literacy is a significant predictor of engaging in unhealthy behaviors. However, the literature regarding the association between health literacy and smoking in university students is very limited. Thus, this study was conducted to examine the association between university students' health literacy and smoking habits. A cross-sectional design was used. A sample of university students (N = 327) was recruited to conduct this study. Data collection was performed using a demographics questionnaire and the health literacy questionnaire. AMOS was used to conduct data analysis using structural equation modeling analysis with maximum likelihood estimation. Different versions of the structural model were compared and evaluated based on specific fit indices criteria. The results showed that 30% of the participants were current smokers. Smoking cigarettes was the most common type of smoking in this study, and 23.1% of the participants were current users of two or more types of smoking (e.g., cigarettes and hookah). The structural model with three latent variables (health literacy, smoking status and type, and smoking frequency and duration) was the one that best fit the data; the model fit indices were X-2 = 305.84, df = 102, p < .001; RMSEA = .068; CFI = .95; CMIN/df = 2.51; TLI = .929; and AIC = 355.75. A single standard deviation increase of health literacy causes .38 decrease in smoking status and type and .13 decrease of smoking frequency and duration. The results showed that health literacy is negatively associated with smoking in a sample of Jordanian university students.
