“…More specifically, higher education (Hultsch & Dixon, 1984), being married and being employed associated with good cognitive functions (West, Crook, & Barron, 1992); clinical conditions such as pain and hypertension (Piccini, Muniz, Sparks, & Bontempo, 2011) and mid-life obesity (Cournot et al, 2006), and depression especially in older adults (Jorm, 1986) have been associated with poorer cognitive ability in later life (Kivipelto et al, 2001). Some longitudinal studies show faster age-related cognitive decline in those with poor education (Agrigoroaei and Lachman, 2011;Colsher and Wallace, 1991;Hahn and Lachman, 2015;Matthews et al, 2004;Nguyen et al, 2002;Osler et al, 2013;Richards et al, 2004;Schaie, 1994). Also poor self-ratings of health and physical activity predicted greater cognitive deterioration (Carmelli et al, 1997) and number of adaptive psychosocial and behavioral factors have been found to be positively associated with change in reasoning abilities (Agrigoroaei and Lachman, 2011).…”
