This study aimed to assess the effect of statins on type two diabetes development. The study comprised of 2,016,094 individuals, including 430,890 people who received a statin, matched to 1,585,204 people not prescribed a statin.
The study found:
(a) Statin users had a 57% increased risk of developing diabetes compared to non-users.
(b) The risk of developing diabetes increased with longer duration of statin use:
(b1) Those who were followed for one to three years had a 22% increased risk of diabetes.
(b2) Those who were followed for 15 to 20 years had a 263% increased risk of diabetes.
Macedo concluded: "Statin use is associated with an increased risk of T2DM (type two diabetes), which increases with longer duration of use".
