[BDSP. Notice produite par INIST R0xJDfC4. Diffusion soumise à autorisation]. The authors examined the validity of a self-administered 180-item food frequency questionnaire in 125 Norwegian men aged 20-55 years who filled in the questionnaire and completed 14-day weighed records in fall 1995 to winter 1995/6. Spearman correlation coefficients between the two measurements ranged from 0.42 for percent of energy from fat to 0.66 for sugar intake (median r=0.51). On average, 39% of the men were classified in the same quartile with the two methods, and 3% in the opposite quartile. Correlation coefficients between intake of fatty acids estimated from the questionnaire and the relative amounts of fatty acids in adipose tissue were : linoleic acid (18 : 2, n-6), r=0.38 ; alpha-linolenic acid (18 : 3, n-3), r=0.42 ; eicosapentaenoic acid (20 : 5, n-3), r=0.52 ; and docosahexaenoic acid (22 : 6, n-3), r=0.49. The correlations for these fatty acids between the total serum lipids and the diet were 0.16,0.28,0.51 and 0.52, respectively. The data suggest that very-long-chain n-3 fatty acids in adipose tissue and total serum lipids reflect the dietary intake of very-long-chain n-3 fatty acids to the same degree. No associations were observed between intake of alpha-tocopherol and concentration in adipose tissue and serum.
