Measuring dietary fatty acid intake: validation of a food-frequency questionnaire against 7d weighed records

There are few validated methods of measuring dietary fatty acid intake that are suitable for epidemiological research. The purpose of the present study was to develop and validate a food-frequency questionnaire (FFQ) developed to measure individual dietary fatty acid intakes against 7d weighed dietary records, in a sample of thirty-one healthy adult volunteers. The FFQ was based on a previously validated questionnaire (DIETQ; Tinuviel Software, Warrington, Ches., UK), adapted to include greater detail on those foods from which the majority of dietary fatty acids are obtained. The FFQ and weighed records were analysed using food nutrient data from McCance and Widdowson's Food Composition Tables, supplemented with a food fatty acid content database (Foodbase, London, UK). Results from the two dietary assessment methods were compared by correlation coefficients and limits of agreement. The mean intake of individual fatty acids tended to be lower when assessed by FFQ. Correlation coefficients comparing unadjusted individual fatty acid intakes assessed by FFQ and weighed records ranged from 0·29 for 18:1n−9 to 0·71 for 20:4n−6. Adjusting for energy intake tended to increase the correlation coefficients between saturated fatty acids and decrease those between unsaturated fatty acids. In conclusion, this food-frequency method provides reliable estimates of dietary intake of many individual fatty acids for use in epidemiological studies.

Dietary Fatty Acid Intake

Background: Studies have found that HDL particle (HDL-P) concentration is inversely associated with risk of CVD, independent of HDL cholesterol (HDL-C). Dietary factors (such as fatty acid intake) have been found to affect levels of HDL-C and influence risk of CVD. However, little is known about the associations of dietary fatty acid with serum HDL-P levels. Hypothesis: We hypothesized that dietary fatty acid associations with HDL-P are independent of HDL-C in men. Methods: Data were from 463 male participants in the 1996-98 cross-sectional INTERLIPID Study, ages 40-59 years, randomly selected from five populations; four in Japan (n=386) and one in Hawaii (n=77). Fatty acid intake was estimated from the mean of four in-depth 24-hour dietary recalls (% kcal per day). Individuals were excluded due to missing data on HDL-P or HDL-C and use of lipid lowering medication. Serum HDL-P was measured using nuclear magnetic resonance and HDL-C was measured using standard methods. Multiple linear regression models were used to assess the association between dietary fatty acid and each of the lipid measures. Results: In men, HDL-P and HDL-C were moderately correlated (r = 0.52, p<0.001). In Model 1 (Table), adjusted for age, country, alcohol intake, BMI, diabetes, hypertension, smoking status, and physical activity, most dietary fatty acids were significantly (p<0.05) associated with HDL-P and HDL-C levels. In Model 2, further adjusted for HDL-C, almost all fatty acids maintained a significant association with HDL-P. In contrast, most associations of fatty acids and HDL-C ceased to be significant after adjustment for HDL-P. Total SFA and omega-3 PUFA remained associated with HDL-C. Conclusion: HDL-P was significantly associated with fatty acid intake, independent of HDL-C. Associations of dietary fatty acid intake and HDL-C level were weaker and generally not independent of HDL-P in men.

Dietary Fatty Acid Intake

AbstractObjectiveThe estimation of dietary intake in population-based studies is often assessed by the FFQ. The objective of our study is to evaluate the validity of an FFQ used to assess dietary fatty acid intake among middle-aged Chinese adults in Southern China.DesignThe method of triads was applied to obtain the validity coefficients (VC) of the FFQ for specific fatty acids. A subsample was randomly selected from an earlier cross-sectional study. The FFQ and 3d dietary records were used for dietary assessment, and the fatty acid composition of erythrocyte membranes was determined as the biomarker.ResultsThe Spearman correlation coefficients between the FFQ and 3d dietary records were moderate to good (r = 0·28–0·66). The VC of the FFQ estimated by the method of triads were 0·72, 0·61, 0·65, 0·75 and 0·67 for MUFA, total n-6 fatty acids, α-linolenic acid, EPA and DHA, respectively. The VC could not be calculated for SFA, PUFA and total n-3 fatty acids because of negative correlations among the three measurements. But, the correlations between the FFQ and the dietary records were moderate for these fatty acids.ConclusionsOur FFQ applied in Southern Chinese adults was valid to estimate their dietary fatty acid intake and was thus suitable for use in a large cohort study.
