Objective
Cardiovascular risk remains high despite statin use. Overweight/obese diabetic persons usually have normal/low LDL‐cholesterol but high C‐reactive protein (CRP) levels. We aimed to examine the effects of intensive lifestyle intervention for weight loss (ILI) on CRP levels in overweight/obese diabetic individuals by statin use.
Design and Methods
Look AHEAD was a randomized trial in overweight/obese type 2 diabetic individuals testing whether ILI would reduce cardiovascular mortality, when compared to usual care. CRP changes in 1,431 participants with biomarker levels, who remained on or off statin treatment for 1 year, were evaluated.
Results
The reduction in CRP levels with ILI at 1 year in men and women on statins was −44.9 and −42.3%, respectively, compared to −13.7 and −21.0% for those on statins and usual care (P < 0.0001). At 1 year, median CRP levels were: 1.8 mg L−1 in participants randomized to ILI on statin therapy; 2.6 mg L−1 for those on statins randomized to usual care and 2.9 mg L−1 for participants not on statins but randomized to ILI. Weight loss was associated with 1‐year CRP reduction (P < 0.0001) in statin and nonstatin users.
Conclusions
Our findings suggest that in overweight/obese diabetic persons, ILI and statin therapy may have substantial additive anti‐inflammatory benefits.
