“…Job demands and job control were the most intensely studied factors of the psychosocial work environment. The result was clearest on HbA 1c , where all studies reported positive associations to both job demands (Cesana et al, 1985;Grossi et al, 2003;Hansen et al, 2003a;Kawakami et al, 2000) and job control (Grossi et al, 2003;Hansen et al, 2003a;Kawakami et al, 2000;Riese et al, 2000). Concentrations of testosterone were negatively associated with job demands (Hansen et al, 2003b) and job control (Berg et al, 1992;Hansen et al, 2003a;Theorell et al, 1990), whereas concentrations of fibrinogen were positively associated with job demands in all population based studies (Clays et al, 2005;Kittel et al, 2002;Steptoe et al, 2003;Tsutsumi et al, 1999), but not in workplace studies (Ishizaki et al, 2001;Riese et al, 2000).…”
