Hyperlipidemia in a Lebanese community: difficulties in definition, diagnosis and decision on when to treat.
Fasting serum cholesterol and triglyceride levels were measured in 131 randomly selected adult members of a Lebanese Community of Western New York. Mean cholesterol levels (males, 217 mg%; females 234 mg%) were higher than those reported from the Lebanon but similar to those reported in most other populations. Mean triglyceride levels (males, 153 mg%; females, 115 mg%) were higher than those reported in most other populations. Twenty-three subjects were hyperlipidemic on the basis of age and frequency distribution adjusted serum lipid levels above the 90th percentile. Clinical and family studies carried out on 13 of these 23 hyperlipidemic subjects suggested that 77% had monogenic hyperlipidemia and 23% primary non-monogenic hyperlipidemia. A high frequency of familial hypercholesterolemia (minimum estimate 0.7%) was found, in keeping with the high frequency of the disorder in Lebanon. The study serves to emphasize the difficulties in defining hyperlipidemia, in establishing a specific diagnosis in the individual patient, and in distinguishing between optimum and normal serum lipid levels.
