Validity and Reliability of a Quantitative Food Frequency Questionnaire Measuring n-3 Fatty Acid Intakes in Cardiac Patients in the Midwest: A Validation Pilot Study

Validity and reliability of an omega-3 fatty acid food frequency questionnaire for first-generation Midwestern Latinas

“…An Australian FFQ that estimates long-chain n-3 polyunsaturated fatty acids (LC n-3 PUFAs) reported Spearman correlations coefficients of 0.75, 0.64, 0.62, and 0.72 for total LC n-3 fatty acids (EPA, docosapentaenoic acid, and DHA fatty acids, respectively) when tested against 3 food records [16]. An FFQ validated against three 24-hour recalls as reference method to estimate n-3 fatty acid intakes in cardiovascular patients in the US Midwest [17] reported Pearson correlation coefficient of 0.42.…”

“…Dietary intakes of n-3 fatty acids and marine food consumption, sources of EPA and DHA of white persons living in the US Midwest, are reported to be low [17,[19][20][21]. Cardiac patients, physically active adults, and low-income US Midwestern pregnant women reported intakes of 0.18 to 10.15, 0.887 ± 0.121, and 1.060 ± 0.030 g/d, respectively [17,21,22].…”

Dietary Omega-3 Intakes in Southern African American and Southern Caucasian Women

“…Data collection instruments included a validated omega-3 southern food frequency questionnaire (SFFQ), including 150 food items, to determine food consumption of women living in the South [19]. The omega-3 SFFQ was designed by a Registered Dietitian Nutritionist and used to identify dietary omega-3 PUFA sources consumed over the previous month.…”

“…The mean age of participants was 32.97 (±7. 19) years. There were 20 (58.8%) SAAW and 13 (38.2%) SCW participants.…”

Development and pilot testing of an omega-3 fatty acid food frequency questionnaire

“…A pilot study was conducted to validate the 152 item FFQ against omega-3 fatty acid intake estimates using food recalls (Ritter-Gooder et al, 2006). The instrument was tested in a convenience group of volunteers, 17 women and 11 men who were involved in the earlier nutrition study.…”
