Mostly, stress is addressed as a general problem, which is why LBP prevention programs are often imprecise.

Therefore, this paper aims (1) to identify the stress types most closely associated with LBP; (2) to examine the relationship between stress accumulation and LBP.</p><p><strong>Methods: </strong>n = 100 call-center workers were approached for participation. Stress levels and LBP were assessed with questionnaires (TICS, ERI, CPG, BPI) and hair cortisol levels were measured (ELISA-KIT, 3-months period).
