Gender differences in the use of alcohol and prescription drugs in relation to job insecurity. Testing a model of mediating factors

Abstract

BackgroundThe results of several studies suggest that economy-related stressors are less distressing for women compared with men. This study proposed to examine the relationship of perceived job insecurity with the use of licit drugs using a theoretical model that considered antecedents and mediators of this association, in order to identify differences between working men and women. MethodsUsing information from the Catalan Health Survey (2010–2014), we selected working individuals aged 16–64 who were primary providers of household income (N=5315). The outcomes were two measures of alcohol consumption (heavy drinking and binge drinking) and the use of hypnotics/sedatives. As antecedents of the exposure to job insecurity we considered the type of contractual relationship and occupational class. The mediating factors were poor mental health, household structure and the hours of housework per week. The theoretical model was assessed using path analysis where the moderating effect of gender was considered in all the associations. ResultsNo differences in the prevalence of job insecurity were found between men and women (17%). Job insecurity (Odds ratio [OR]=1.35, 95% confidence interval [CI]=1.23–1.48) and house workload (OR=1.01, 95% CI=1.00–1.02) were positively associated with poor mental health, with no significant interactions with gender. Poor mental health was significantly associated with binge drinking (OR=1.23, 95% CI=1.13–1.33) and with the use of hypnotics/sedatives (OR=1.71, 95% CI=1.53–1.91). House workload showed a direct negative association with binge drinking (OR=0.99, 95% CI=0.98–1.00), while those in households with no children were more likely to be binge drinkers, with no significant interactions with gender. An alternative model had better fitting results for heavy drinking. ConclusionNo gender differences were found in the association of job insecurity with mental health nor with the use of substances among primary providers of household income, emphasising the importance of social roles when assessing differences in mental health among men and women.
