The percentage compositions of fatty acids in serum cholesteryl esters and phospholipids were analysed with gas chromatography in 759 nine- to 24-year-old Finns. The correlations of serum fatty acids with dietary fat intake data were calculated from a 48-h recall survey. The dietary P/S ratio had correlations of r = 0.50 and r = 0.40 with linoleate (18:2) in serum cholesteryl esters and phospholipids, respectively. The intake of fish and fish products correlated positively with the percentages of eicosapentaenoate (20:5 n-3) and docosahexaenoate (22:6 n-3) in both cholesteryl esters and phospholipids. Dietary intake of saturated fat correlated positively with the percentages of all saturated fatty acids in cholesteryl esters and with myristate (14:0) in phospholipids. The intake of monounsaturated fats did not correlate positively with serum monoenes. In conclusion, the dietary P/S ratio is well reflected in the fatty acid composition of serum cholesteryl esters and phospholipids, the intake of saturated fats less well, and the intake of monounsaturated fats not at all.
采用气相色谱法分析了759名9至24岁芬兰人的血清胆固醇酯和磷脂中脂肪酸的百分比组成。根据48小时回忆调查计算血清脂肪酸与膳食脂肪摄入数据的相关性。膳食P/S比值与血清胆固醇酯和磷脂中亚油酸（18:2）的相关性分别为r = 0.50和r = 0.40。鱼类和鱼类产品的摄入量与胆固醇酯和磷脂中二十碳五烯酸（20:5 n-3）和二十二碳六烯酸（22:6 n-3）的百分比呈正相关。饱和脂肪的膳食摄入量与胆固醇酯中所有饱和脂肪酸的百分比以及磷脂中肉豆蔻酸（14:0）的百分比呈正相关。单不饱和脂肪的摄入量与血清单烯酸没有正相关。总之，膳食P/S比值在血清胆固醇酯和磷脂的脂肪酸组成中得到很好的反映，饱和脂肪的摄入量反映较差，而单不饱和脂肪的摄入量则完全没有反映。
