Status of medication literacy and its related factors among undergraduate students in Shanxi Province, China: A cross-sectional study.

Abstract

Medication safety problem has always been the focus of healthcare providers and public health community scholars. As the backbone of the future society, the mastery of college students' knowledge to use medicine will directly affect the level of medication literacy (ML) of the public in the future. The purpose of this study was to investigate the current ML of college students in Shanxi Province and to identify its related factors. A cluster random sampling method was utilized to select 800 college students from 10 universities in Shanxi province as participants from 21March to 10 April 2020. After quality control, 763valid questionnaires were collected (effective rate 95.4%). This study applied the ML scale adapted from the 14-item health literacy scale (HLS-14) to estimate ML, which contains functional ML, communicative ML and critical ML dimensions to estimate the ML situation. Then, we used structural equation modelling (SEM) to test the hypothesized relationship among three dimensions of ML, self-evaluated health status and safety medication science popularization activities on campus. The results showed that the reliability and validity of the ML scale were good. The average score of ML level of college students in Shanxi Province was 44 points, and the interquartile range was 40-48 points (full score is 65 points). The proportion of high ML level was estimated at as low as 26.7%. 73.1% participants had an average level, and only 1 participant (0.1%) had a low level of ML. Univariate analysis showed that the ML level was significantly influenced by gender, universities, field of study, academic performance and ethnic group (p<0.05). SEM showed that functional ML (λ=0.01) and communicative ML (λ=0.75) had a direct positive association with critical ML. Meanwhile, the model also had a mediating effect. Functional ML had an indirect positive association with critical ML through the mediating effect of communicative ML (λ=0.11). In addition, both self-evaluated health status and safety medication science popularization activities on campus had an indirect positive association with critical ML through the mediating effect of functional ML and communicative ML. The study revealed that the ML of most college students in Shanxi Province was at the average level. Among them, medical college student (including pharmacy, nursing, public health, preventive medicine, basic medicine and clinical medicine students), the Han nationality students (the students of China's majority ethnic group), students of good self-evaluated health status, and students who were more exposed to safety medication science popularization activities had a relatively higher ML level. Moreover, it highlighted the importance of self-evaluated health status and safety medication science popularization activities on campus to ML.
