This study was a follow-up of the Christiansen study which was completed in 1967. Dr. Christiansen's 26 subjects ranged in age from 33 to 60 years. Ten were designated as controls and the other 16 were placed on a high polyunsaturated fatty acid (PUFA) diet for a period of 26 weeks .
The purpose of doing a follow-up was to determine what effect the study had on present dietary patterns, serum lipid levels and rate of erythrocyte hemolysis.
Eighteen of the original subjects participated in this study. Of these 18, nine were from the control group and nine were from the experimental group. There were nine women and nine men. The serum cholesterol and triglyceride levels, rate of erythrocyte hemolysis and blood pressure reading were determined. General health status and dietary pattern were determined through the use of a questionnaire.
The results of the questionnaire indicate that the experimental diet of the original study had influenced the present diet of the study's subjects. The use of vegetable oils was increased and the consumption of eggs and whole milk was decreased. The study had little effect on the consumption of beef, pork, fish and chicken.
The rate of erythrocyte hemolysis was greater for the control group (non-instructed) than for the experimental group (instructed). The mean values were 12. 65 and 9. 49 percent, respectively. The results indicate that there was no depletion of tocopherol levels due to continued use of PUFA.
Serum triglyceride levels varied from 60 to 72 mg percent. Mean values for men were slightly higher than for the women. The means for the instructed and non-instructed groups were almost the same (6 7. 2 and 6 7. 0 mg percent, respectively).
The cholesterol values ranged from 139 to 252 mg percent. The mean values were close to those at the end of the previous study (192 and 188 mg percent, respectively). There was no correlation between cholesterol values and the rate of erythrocyte hemolysis or triglyceride values.
