Introduction:

To determine the prevalence of misconceptions in Health Sciences students.

Materials and methods:

Quantitative approach; basic type, non-experimental design and simple descriptive scope. Likewise, it is important to specify that the instrument used was a questionnaire (19 items), which measures the five dimensions: vaccines, cancer, pain management, mental health and epilepsy.

Results:

They show polarization and misinformation on various health topics. Regarding vaccines, the majority reject myths such as the relationship with autism (91,2%; p = 0,009), although variabilities persist (M = 8,18; SD = 1,96). Regarding cancer, uncertainties predominate regarding its severity and treatments (64.7% and 47,1% unsure), with partial knowledge (M = 6,54; SD = 1,34; p = 0,003). In pain management, gaps are observed regarding its multidimensionality (M=6,68; SD=1,47; p<0.001). In mental health, stigma persists (M=5,15; p<0,001). Regarding epilepsy, although 97,1% reject its contagion, confusion persists regarding causes and treatments (M=5,15).

Discussion:

It can be concluded that specific and accessible educational interventions are needed to combat erroneous beliefs and promote informed decisions based on scientific evidence.
