Background. Peculiarities of behavior and nutrition, living conditions, consumption of
alcohol, smoking, and psychological state are factors that can influence students’ academic
performance. Material and methods. 327 healthy 1-2-year students aged 18.8±0.1 years were
interviewed about lifestyle, consumption of various types of foods and alcohol, intensity and
duration of smoking, fasting experience, satisfaction with their degree of wealth and family
relationships, sleep duration and sleep disorders, and the number of physical and psychological
traumas. Anxiety, self-esteem, academic ability, and academic performance were determined.
Results. Students’ nighttime sleep duration was 7.1±0.1 hours; sleep disorders were observed
in 40.1% of students. Vegetables were consumed daily by 31.4% students. 70.8% of males
and 57.8% of females were satisfied with wealth. The females’ academic performance was
higher. Alcohol consumption was higher among females from wealthy families, but lower than
among males. Conclusions. Academic performance was negatively related to the weekly dose
of alcohol consumed. The academic ability level of abstainers was higher than that of alcohol
users. Alcohol users showed an inverse relationship between alcohol consumption and anxiety.
Differences were found in factors contributing to alcohol use by young men and women.
Academic performance was lower in individuals who fasted for more than one day
