Question explored with the scientific record
Is there evidence to support a healthy active 67 yr male with slightly elevated cholesterol taking statins
For a healthy active 67-year-old man with slightly elevated cholesterol, the evidence for statins is weak and the trade-offs are real.
The strongest evidence for statin benefit in primary prevention for men over 70 comes from the JUPITER trial, which found a 39% reduction in a composite of cardiovascular events with rosuvastatin in people with elevated CRP [6]. But that trial enrolled people with normal LDL and high inflammation, not "slightly elevated cholesterol." For primary prevention in men over 75, the CTT meta-analysis found an 8% risk reduction that did not reach statistical significance [6]. A 2022 study of men not on statins found a U-shaped relationship: the lowest risk of death was at non-HDL cholesterol around 142-144 mg/dL, and levels below 100 mg/dL were associated with nearly double the risk of death [1].
The harms are documented. A meta-analysis of randomized trials found statins increase the risk of new-onset diabetes by about 13% (RR 1.13) [4]. A larger meta-analysis found an odds ratio of 1.61 [3]. The risk is dose-dependent: high-intensity statins produce more diabetes than moderate-intensity [5]. Muscle symptoms are common, though the rate of serious rhabdomyolysis is low [7].
The key question is whether this man's "slightly elevated" cholesterol actually puts him at risk. The U-shaped data suggests that for many men, moderate cholesterol is protective, not dangerous [1]. Without a formal risk calculation that accounts for his age, activity level, and other factors, the default should be no intervention. Lifestyle factors—diet, exercise, not smoking—are associated with far larger risk reductions than statins [2].
My call: the evidence does not support starting a statin for a healthy active 67-year-old man with slightly elevated cholesterol. Confidence: moderate.

Statin Therapy and Risk of Developing Type 2 Diabetes: A Meta-Analysis
In a meta-analysis of five hypothesis-testing randomized trials, statin therapy was associated with a small but significant increase in incident diabetes (RR 1.13, 95% CI 1.03-1.24), but the association was attenuated and non-significant when WOSCOPS was included.

Statin Therapy for Primary and Secondary Prevention in Older Adults
Evidence supports statin therapy for secondary prevention in older adults and for primary prevention in selected high-risk older patients; age alone should not deter statin therapy.

Should statin therapy be used in medication of elderly patients?
The author concludes that statin therapy is useful in elderly patients, with mandatory use in secondary prevention and lower, individually adjusted doses in primary prevention, while excluding patients with terminal illness, frailty, or dialysis.
