Models adjusted to evaluated associations of job stress, psychological distress and rank with physical activity among military personnel – results of the multivariate analysis by multiple linear regression via generalized linear models.

Model 1: Simultaneous adjustment of the independent variables (job stress, psychological distress and rank).

Model 2: Simultaneous adjustment of the independent variables with socio-demographic variables (age, schooling, income and marital status).

β = Coefficient.

aTS (total score) = OPA + SEL + PALL.

bReference category.

cOPA = occupational physical activity.

dSEL = physical activity in sports/physical exercise during leisure.

ePALL = other physical activities during leisure and in walking.
