In a randomly selected group of 444 men and women divided into three age groups: 35-44 years, 45-64 years and 55-64 years, the composition of fatty acids in total serum lipids was determined by gas chromatography, with particular reference to EFA (linoleic, linolenic, arachidonic acids) and the P:S index. The results showed that the levels of EFA and PUFA (all unsaturated fatty acids) were significantly higher in women than in men in this population. The mean EFA value in women was 31.3% and in men 29.3%. The PUFA level was 33.7% and 31.7% respectively. Similarly, the P:S index in women was significantly higher - 1.02 than in men - 0.94. In the light of these results, it may be assumed, that the serum EFA level in the studied subjects points to an intake of those acids covering up to 3% of the total energy of the daily food ration.

Badanie składu kwasów tłuszczowych przeprowadzono ogółem u 444 mężczyzn i kobiet w trzech grupach wiekowych: 35-44 lat, 45-54 lat i 55-64 lat. Zawartość poszczególnych kwasów tłuszczowych w lipidach całkowitych surowicy krwi oznaczono metodą chromatografii gazowej.Z badań wynika, że zawartość NNKT (kwas linolowy 18:2, n-6; kwas linolenowy - 18:3, n-3 oraz kwas arachidonowy - 20:4, n-6) i wszystkich kwasów wielonienasyconych - P średnio w całej populacji kobiet jest statystycznie istotnie (przy p≤0,05) wyższa niż u mężczyzn i wynosi: u kobiet NNKT - 31,31%, u mężczyzn 29,31%; u kobiet P - 33,73%, u mężczyzn - 31,74%. Podobnie wskaźnik P:S u kobiet jest wyższy statystycznie istotnie niż u mężczyzn i wynosi 1,02 w porównaniu z 0,94. Na podstawie wcześniejszych podobnych badań można ocenić udział NNKT w dostarczaniu energii w dziennych racjach pokarmowych badanych mężczyzn i kobiet na poziomie około 3%.
