The aim of the work was to compare physical activity, taking care of one’s health and self-evaluations of physical fitness
and health of subjects from three successive generations. Research conducted between 2013–2017 embraced 1,580 subjects,
including 400 students engaged in physical culture and health promotion, their 496 parents and 684 grandparents. The
diagnostic survey method was used, applying a questionnaire, interview and observation. Standard statistical methods
were applied: trait frequency, χ2 test and multiple correspondence analysis. It was found that physical activity, caring for
one’s health and self-evaluation of health and physical fitness were more similar within one generation (male student vs.
female student, mother vs. father, grandmother vs. grandfather) than between adjacent generations (students vs. parents,
parents vs. grandparents). The behavior and self-evaluation of female students, analyzed within the same sex, were
similar to those of their mothers and grandmothers; the behavior and self-evaluation of male students were similar to
those of their fathers and grandfathers. Physical activity, caring for health and self-evaluation of physical fitness and
health were determined by age, sex, marital status, place of residence and education. The continuation of research in this
field is of major importance in the health prevention of Polish society
