摘要：We compared fatty acid intake estimated from our 138-item food frequency questionnaire (FFQ) with 28-day weighed dietary records among a subgroup of JPHC Study Cohort 1 (102 men and 113 women), and with the corresponding two serum phospholipid levels (88 men). Spearman rank correlation coeffi- cients between fatty acid intakes estimated from FFQ and intakes estimated from DR were as follows: saturated fatty acid, r=0.61 and r=0.60; monounsaturated fatty acid, r=0.50 and r=0.44; for energy adjusted value and Eicosapentaenoic acid (EPA), r=0.62 and r=0.55; docosahexaenoic acid (DHA), r=0.61 and r=0.50; for percentage of total fatty acid intake in men and women, respectively. Spearman rank correlation coefficients between fatty acid intakes estimated from FFQ and the corresponding serum phospholipid levels (% of total fatty acid) were as follows: EPA, r=0.43 and r=0.59; DHA, r=0.35 and r=0.49; for crude value (g/day) and percentage of total fatty acid intake, respectively. In conclusion, relatively high correlations were observed for SFA, MUFA and marine-origin n-3 polyunsaturated fatty acid, whereas we must take into account the indicator of each fatty acid intake when using the data of fatty acid intake assessed with FFQ for JPHC study.
