Introduction:
According to modern knowledge, we distinguish many factors conditioning human health. Among them, the most important is lifestyle. During the university education period, the first independent attempts and decisions are made, not only those related to life choices, but also decisions related to health behaviours that will have a consequence in adult life. The aim of the study was to assess the positive health behaviours among students of Lublin universities and their selected determinants.

Material and methods:
The study was conducted using the PAPI method from March to May 2017 among 410 male students. The study employed the Positive Health Behaviour Scale (PHBS) for adults and sociodemographic questions. The results of the study were subjected to statistical analysis.

Results:
The obtained results of the study carried out among students using PHBS allowed the authors to state that the respondents obtained the highest result in Subscale IV. “Safety” (2.46 ± 0.59), subsequently in Subscale III. “Relaxation and behaviours connected with psychosocial health” (1.67 ± 0.53). The lowest rated subscale was Subscale I. “Nutrition” (1.28 ± 0.52). Statistical analysis showed that age, the place of residence, place of residence during studies, field of studies, occurrence of cancer in the family and self-assessment of health condition determines the assessment of positive health behaviours (p < 0.05).

Conclusions:
The ranking of positive health behaviours among male students of Lublin universities is as follows: “Safety”, “Relaxation and behaviours connected with psychosocial health”, “Physical activity”, “Taking care of one’s body” and “Nutrition”.
