One of the aims of this study was to assess the association of low density lipoprotein (LDL) cholesterol levels with diabetes risk. The study included 6,011 individuals, (average age 50 years), who were not treated with cholesterol lowering or antihypertensive medications and who were free from cardiovascular disease at the start of the study. Diabetes was assessed at the next examination (average 4.5 years later).

The study found that each standard deviation increase in LDL levels was associated with a 19% reduced risk of diabetes. 

Andersson concluded: "These observations may contribute to our understanding of why lipid-lowering treatment may cause diabetes in some individuals."
