Health literacy (HL) is an aspect that has been widely studied. However, in the military population there are hardly any studies on the influence of educational variables. Knowing the level of health literacy of military professionals is important as it has an impact on adequate health decision making, avoids the abuse of health services and makes it possible to ask for help when needed, especially in aspects related to mental health. The aim of this study was to measure the level of literacy, as well as its association with other training variables in a sample of military personnel. The study was carried out in 695 military personnel of the Spanish Army. A cross-sectional observational design was used, using a survey with the HLS-EU-Q47 scale. Among the results, it stands out that the level of health literacy of the military is high compared to the rest of the population. The results showed that the level of HL does not seem to be influenced by the level of languages, nor by the degree they hold, nor by experiences abroad. On the other hand, it was observed that the performance of professional internships and work in multidisciplinary teams, extracurricular training, does influence the level of HL, especially in the dimension related to health promotion. This fact seems to mean that the military have learned during these experiences to keep abreast of health-related issues, to understand, to value and to form a considered opinion on health-related information.
