• The differences in the morbidity and mortality of cardiovascular diseases between Sri Lankan and Japanese populations might be explained by the differences in their diet, especially fat. To test the hypothesis that the fatty acid (FA) compositions differ between Sri Lankan and Japanese populations and that high concentrations of n-3 polyunsaturated FAs and linoleic acid are associated with a low level of arteriosclerosis, the authors compared the circulating FA compositions between Sri Lankan and Japanese populations and examined the association of the circulating FA composition with arterial stiffness in each population. The study participants were patients with diabetes, dyslipidemia, or hypertension in Sri Lanka (n = 100) or Japan (n = 236). Serum FA compositions were measured by gas chromatography. Arterial stiffness was measured using the cardio-ankle vascular index (CAVI). Analysis of covariance was used to compare the FA compositions between the populations. Multiple regression was used to assess the association between each FA and CAVI levels. The concentrations of myristic, γ-linolenic, dihomo-γ-linolenic, and arachidonic acids were higher in the Sri Lankan patients than in the Japanese patients. In contrast, the concentrations of linoleic, α-linolenic, and eicosapentaenoic acids were higher in the Japanese patients than in the Sri Lankan patients. Although no associations of n-3 polyunsaturated FAs and linoleic acid with CAVI were observed in both patient populations, odd-chain saturated FAs (pentadecanoic and heptadecanoic acids) were significantly inversely associated with CAVI levels in the Sri Lankan (P for trend = .03) but not the Japanese patients. The odd-chain saturated FAs might be inversely associated with atherosclerosis in this Sri Lankan population.
