Abstract

OBJECTIVE:

To investigate the association between cholesterol lowering interventions and risk of death from suicide, accident, or trauma (non-illness mortality).

DESIGN:

Meta-analysis of the non-illness mortality outcomes of large, randomised clinical trials of cholesterol lowering treatments.

STUDIES REVIEWED:

19 out of 21 eligible trials that had data available on non-illness mortality. INTERVENTIONS REVIEWED: Dietary modification, drug treatment, or partial ileal bypass surgery for 1-10 years.

MAIN OUTCOME MEASURE:

Deaths from suicides, accidents, and violence in treatment groups compared with control groups.

RESULTS:

Across all trials, the odds ratio of non-illness mortality in the treated groups, relative to control groups, was 1.18 (95% confidence interval 0.91 to 1.52; P=0.20). The odds ratios were 1.28 (0.94 to 1.74; P=0.12) for primary prevention trials and 1.00 (0.65 to 1.55; P=0.98) for secondary prevention trials. Randomised clinical trials using statins did not show a treatment related rise in non-illness mortality (0.84, 0.50 to 1.41; P=0.50), whereas a trend toward increased deaths from suicide and violence was observed in trials of dietary interventions and non-statin drugs (1.32, 0.98 to 1.77; P=0.06). No relation was found between the magnitude of cholesterol reduction and non-illness mortality (P=0.23).

CONCLUSION:

Currently available evidence does not indicate that non-illness mortality is increased significantly by cholesterol lowering treatments. A modest increase may occur with dietary interventions and non-statin drugs.
