Status of polyunsaturated fatty acids in serum of persons aged 10-72 in Nepal.
The fatty acid composition of serum was measured for persons aged 10-72 (42 males and 38 females) living in southeastern Nepal.
The mean amounts of PUFA and n-6 PUFA were significantly higher for males (79.8 and 72.7 mg/100 ml, respectively) than for females (68.9 and 62.3 mg/100 ml, respectively) (p<0.05).
The ratios of PUFA/SFA (0.92 and 0.88 for males and females, respectively) and of n-3/n-6 PUFA (0.093 and 0.104) were about the same for both sexes.
The percentages of PUFA and MUFA were 31.6 and 33.0% for males and 30.4 and 34.4% for females, respectively, and the percentage of PUFA showed an inverse correlation with that of MUFA (r=-0.82, p<0.001).
The percentage of PUFA and the ratio of PUFA/SFA correlated inversely with the level of triglycerides (TG) (r=-0.39 and r=-0.41, p<0.001, respectively), which showed a positive correlation with the level of oleic acid (18 : 1n-9) (r=0.88, p<0.001).
These results revealed that when the TG level was high, the level of oleic acid was high but the PUFA percentage and the PUFA/SFA ratio were low.
Thus, a tendency of essential fatty acid deficiency was found with an increased TG level in the Nepalese people studied.
