Association between beliefs in medical conspiracy theories and health behaviors among medical and healthcare students. Implications for professional practice

Abstract Background While conspiracy theories cover many different themes, medical conspiracy theories (MCTs) have become particularly prevalent in modern societies. As beliefs in MCTs can become a source of “infodemics”, influence individual health behaviors and cause distrust in medical institutions and personnel, healthcare workers must find ways to overturn patients’ conspiracy thinking. However, as the medical world is not free of these beliefs, in this study, we investigated beliefs in MCTs among medical and health science students and their association with reported health behaviors. Methods Our sample was derived from a self-administered, anonymized, computer-assisted web survey conducted among 1,175 medical and health science students enrolled at the Poznan University of Medical Sciences, Poland. Results From a set of twenty different MCTs, one-third of students rejected all of them, 18% believed in one, 15% in two, 10% in three, and 24% supported four or more conspiracy theories. In addition, many students were hesitant or unsure about MCTs. We also found that nursing and midwifery students were the most likely to believe in MCTs, while medical and dental students were the least supportive. Support for MCTs was higher among students in the early years of their studies and who declared themselves religious and conservative. This study also highlights the association between students’ support for MCTs and their reported health behaviors, including avoiding vaccinations, using alternative medicine, taking vitamin C, or using social media as an essential source of health information. Conclusions As medical and health science students are prone to conspiratorial thinking, they should be trained to act as a trusted and reliable source of medical information, to mitigate conspiratorial beliefs, and to act as role models for their patients and society, effectively shaping health behaviors in the population.
