摘要：The fatty acid composition of serum phospholipids of 277 persons, aged 63-97y (average 78y), was measured. Subjects had been living independently in a facility with full food service for 1y or more. Eleven saturated and unsaturated fatty acids were detected in all the subjects. Stearic acid (18:0) was positively ( p =0.028) and dihomo-gamma-linolenic acid (20:3 n -6) was negatively ( p =0.012) related to age. Arachidonic acid (20:4 n -6) tended to decline with age (p=0.063). In addition, the oleic acid (18:1 n -9)/18:0 ratio decreased significantly with age ( p =0.024). 18:0 and total saturated fatty acids were lower, and linoleic acid (18:2 n -6) and 20:4 n -6 and n -6 fatty acids were higher in males than in females. These results suggest deficits in n -6 essential fatty acids as age advances, particularly in females.
