The aim of this work was to investigate the mechanisms underlying the risk of type two diabetes associated with statins. The study included 8,749 non-diabetic men, aged 45–73 years, who were followed up for 5.9 years.

The study found:
(a) Individuals taking statins had a 46% increased risk of developing diabetes compared to individuals not taking statins.
(b)  Insulin sensitivity was decreased by 24% in individuals on statin treatment compared with individuals without statin treatment.
(c)  Insulin  secretion was decreased by 12% in individuals on statin treatment compared with individuals without statin treatment.

Cederberg concluded: "Statin treatment increased the risk of type 2 diabetes by 46%, attributable to decreases in insulin sensitivity and insulin secretion".
