Blood glucose control and aggressiveness in females

A limited number of studies have reported an association between hypoglycaemic tendencies and aggressiveness in psychiatric populations. Only one study has, to date, examined the phenomenon in nonpsychiatric individuals. The present study aimed to support and extend this finding by considering the ability to control blood glucose in young adult females. Blood glucose control was measured during a 3.5 h glucose tolerance test. A low level of blood glucose at the nadir, but not the rate of decline in blood glucose to the nadir, correlated significantly with measures of aggression. Among healthy females a low, but not necessarily hypoglycaemic, blood glucose level is associated with aggressiveness.
