Work and non-work stressors, @entity458 and XXXX : evidence from a 14-year study on Canadian workers.

@entity1 @entity101 @entity458 @entity28
OBJECTIVE: This study aimed to evaluate the contribution of work, non-work and individual factors to @entity28 with regard to gender-related differences, and to clarify the mediating role that @entity458 plays in these dynamics in Canada from 1994 to 2008 using the Canadian National Population Health Survey (NPHS). DESIGN: Longitudinal. SETTINGS: The NPHS is a randomised longitudinal cohort study with biennial interviews of the Canadian adult population from 18 to 64. @entity1 : 5925 non-obese workers in cycle 1 (49% were @entity1 ). MEASUREMENTS: @entity28 was measured using the body mass index (BMI), with a threshold of BMI >30   kg/m(2). BMI was corrected in accordance with the recommendations of Connor Gorber et al to adjust for gender bias in responses. RESULTS: Of the work characteristics evaluated, only decision authority was associated with @entity28 for @entity1 but not for @entity1 . Living as a couple, @entity1 -related strains, psychotropic drug use, @entity101 , being physically inactive and low @entity458 were @entity28 risk factors but were not moderated by gender. Overall, @entity458 did not mediate the associations that work factors have on @entity28 . CONCLUSIONS: Our study suggests that @entity1 and @entity1 differ little in the extent to which work, non-work and individual factors predict @entity28 . However, for @entity1 , the level of decision authority is associated with a lower @entity28 risk. In addition, @entity458 did not mediate the contribution of work factors and actually seems, contrary to expectations, to decrease the @entity28 risk when work, non-work and individual factors are taken into account.
