Prevalence of self-medication with antibiotics and its related factors among Chinese residents: a cross-sectional study.

BACKGROUND

Self-medication is one of the most common forms of inappropriate use of antibiotics. This study aimed to assess the prevalence of self-medication with antibiotics (SMA) in China and evaluate the related factors.

METHODS

A cross-sectional survey was conducted in Wuhan, Hubei, China from July 1, 2019 to July 31, 2019. Participants were recruited in public places to answer a structured questionnaire. The information of participants' social demographic characteristics, antibiotic knowledge and health beliefs were collected. Binary Logistics regression analysis was used to examine the associated factors of SMA.

RESULTS

Of the 3206 participants, 10.32% reported SMA in the past 6 months. Participants who with middle or high perceived barriers to seek health care services showed a higher likelihood of SMA (P < 0.05). Participants who with middle or high perceived threats of self-medication, and who with middle or high self-efficacy to overcome obstacles showed a lower likelihood of SMA (P < 0.05).

CONCLUSIONS

Compared with developed countries, the prevalence of SMA in China is still higher. Measures to conduct public health education and improve the accessibility of health services are crucial to decrease the overall self-medication rate in China.
