Hypocholesterolemia has been reported in epidemiologic studies to be associated with increased mortality from noncardiovascular causes.
Low cholesterol concentrations have been reported in various pathologic conditions and in institutionalized elderly patients, and seem to be associated with poor outcome.
The role of nutritional factors in the genesis of hypocholesterolemia was investigated in 380 free-living elderly subjects.
Subjects in the lowest cholesterol quartile had lower free triidothyronine and prealbumin concentrations and a lower Folstein's score (a minimental test) than did those in the other quartiles.
They did not differ from the other subjects for energy or nutrient intakes.
Only 12 subjects (9 men and 3 women) had cholesterol concentrations<3.62 mmol/L : the men had low free triidothyronine, free thyroxine, and prealbumin concentrations but normal energy and nutrient intakes, whereas the women differed from those with normal cholesterol concentrations for biological and nutritional data.
These results indicate that low cholesterol concentration is a nonspecific feature of poor health status that is independent of nutrient or energy intake.
The role of nutrient factors as a determinant of cholesterol concentration appears marginal in free-living elderly subjects.
