Factores psicosociales laborales asociados a riesgo de sintomatología depresiva en trabajadores de una empresa minera

in a random sample of 303 workers at a chilean mining company we examined the association between psychosocial work factors and the risk of depressive symptoms. we administered a modified eqcotesst questionnaire, using the scales of psychological demands, job control, effort-reward imbalance, distress, drug consumption and depressive symptoms. results showed differences in risk of depressive symptoms among those with low social support compared with those with high support (rr: 1.79 (ci: 1.19 - 2.71 p = 0.006)); high effort-reward imbalance compared to those with low imbalance ((rr: 1.78 (ci: 1.19 - 2.66 p = 0.004)), high psychological demands compared with those with low demands (rr: 1.83 (ci: 1.22 - 2.75 p = 0.003 )); high or very high stress compared with those with low stress (rr 4.5 (ci: 3.27 - 6.32 p = 0.000)), and between those who consume more than one psychotropic drug and those who do not (rr: 4.2; (ci: 2.75 - 6.47 p = 0.000)). our findings are consistent with studies showing the relationship between psychosocial factors and mental health work and suggest the need for similar studies in other working populations.
