Erythrocyte fatty acid composition and gallstone disease: results of an epidemiological survey

Within a cross-sectional study on the epidemiology of gallstone disease (GD) and its related factors, relation of GD to habitual dietary fat types has been investigated. Gallbladder status was assessed by ultrasound; fatty acid composition of the habitual diet was estimated by GLC of erythrocyte fatty acids. No differences in erythrocyte fatty acid composition were observed between women without gallstones, women with gallstones (aware and unaware of their condition), and women who had cholecystectomies. Multivariate analysis, including other diet- dependent and gallstone-related variables, showed no significant association between erythrocyte fatty acids and risk for gallstones. However, raised erythrocyte linoleic:saturated ratio was associated with increased risk for gallstones only in women with very low serum triglycerides. This latter finding needs further confirmation and is presently unexplainable. Our results suggest that dietary fatty acids do not play a major role in GD.
