Evidence suggests that since working hours have risen dramatically during the past half-century (Cha, 2013), both objective and subjective workload have turned into a major health concern. A growing body of evidence suggests that workload may be associated with adverse health outcomes such as Cardio-Vascular Diseases (CVD) - the leading cause of death in the world (Kang et al., 2012), as well as with the onset of the metabolic syndrome (MS), a constellation of cardiovascular risk factors that has been associated with morbidity and mortality (Han & Lean, 2011).

Because of the epidemic of over-weight and sedentary lifestyle world-wide, the MS is becoming increasingly common and research suggest its prevalence already reached 34% of the adult population (Mozumdar & Liguori, 2011). Despite global concern regarding the MS and its negative consecuences, no study to date have prospectivly investigated the relationship between long working hours and the MS. The first aim of the present study is thus to find out whether objective and subjective job demands are associated with new onset of the MS among employed adults in Israel, where 19% percent of employees work more than 50 hours a week (compared to an average of 9% only among the OECD countries, OECD, 2011). 

Furthermore, drawing on the conservation of resources theory (Hobfoll, 1989), and on Kiecolt-Glaser, McGuire, Robles, & Glaser (2002), we want to extend past research by prospectively testing whether two negative affective states, that result, in part, from prolonged exposure to high levels of job demands (i.e. job burnout and depression), mediate the association between job demands and the MS.

Finally, we wish to expand prior research by investigating the possible moderated-mediation effects of three resources: a personal resource (self-efficacy), a behavioral resource

(physical activity) and an occupational resource (perceived work control), all suggested to attenuate the detrimental effect of resource loss associated with objective and subjective  workload,  on health.

The findings will assist organizations to identify and support employees at higher risk, and develop interventions that may buffer the negative cascading effects of workload on health.
