“…According to Robinson et al (11) , higher consumption reported by FFQ may result from the bigger portions used in the FFQ or be due to overreporting of intake frequency. To develop the FFQ used in the present study, nutrient intake was adjusted by energy and within-person variation (17) in order to reduce the risk of the instrument overestimating intake. Although the food list of the FFQ assessed is very similar to the lists used in other FFQ devised for use in Brazil (29,30) , portion sizes were consistently larger.…”

“…Since 24hR and FFQ might have correlated errors, related to memory and estimation of portion size, the use of multiple DR or weighed records as the reference method is recommended. Nevertheless, when literacy or motivation of participants is low, the 24hR might be applied as the reference measure of nutrient intake (6) .In an earlier study, an FFQ was developed for use in pregnant women attended by the national health-care system in the municipality of Ribeirão Preto, São Paulo State, Brazil (17) . The aim of the present study was to verify the relative validity of this FFQ against the 24hR instrument for estimating nutrient intakes over the three trimesters of pregnancy.…”

Objective: To evaluate the ability of an FFQ, designed for use in Brazilian pregnant women, to estimate nutrient intakes during pregnancy. Design: A prospective study was conducted among 103 pregnant women attended by the Brazilian national health-care service. Food intake during pregnancy was evaluated by three 24 h dietary recalls (24hR), one per trimester of pregnancy, and also by two FFQ. The FFQ with eighty-five food items included questions about frequency of intake and portion sizes during two periods: the first 24 weeks of pregnancy and the pregnancy period as a whole. Deattenuated Pearson's correlation coefficients and joint classification into quartiles of nutrient intake were applied. Setting: Ribeirão Preto, São Paulo State, Brazil. Subjects: One hundred and three pregnant women, aged 18-35 years. Results: Acceptable correlation coefficients (r . 0?35) were found for Ca, K, Zn, Mg, fibre, vitamin C, niacin and folic acid for intake for the first 24 weeks; and for energy, lipids, protein, carbohydrate, Fe, K, Zn, fibre, vitamin B 6 , riboflavin and niacin for the gestational period as a whole. A high proportion of study participants ($70 %) were categorized into the same or adjacent quartiles for estimated energy, carbohydrate, Ca, K, fibre, Zn, cholesterol, vitamin A, riboflavin, niacin, vitamin C, vitamin E and folic acid. Gross misclassification ranged from 2?3 % (dietary fibre) to 12?5 % (vitamin A, thiamin and SFA). Conclusions: The FFQ is a useful tool for assessing categories of nutrient intake during pregnancy, since a high proportion of women were classified into the same or adjacent quartiles. Keywords FFQ Pregnant women Validation studiesInadequate maternal diet is a relevant risk factor for complications during pregnancy (1,2) , impaired fetal development (3) and may also be linked to higher risk of chronic diseases during childhood (4) and adult life (5) .The FFQ is a method widely used in epidemiological studies aimed at categorizing individuals into different levels of consumption and determining their relationships with health outcomes (6,7) . The FFQ's ability to assess dietary intake of pregnant women is due to the fact this method spans a longer time frame, thus allowing the detection of changes in dietary intake during each trimester of pregnancy (8)(9)(10)(11) .Validation studies of FFQ for use in pregnant women have shown that nutrient estimates using this method exhibit high levels of agreement with intake estimates using the 24 h dietary recall (24hR) (12)(13)(14) or daily records (DR) (15,16) , suggesting a good accuracy of the FFQ for assessing dietary intake in this population group. Since 24hR and FFQ might have correlated errors, related to memory and estimation of portion size, the use of multiple DR or weighed records as the reference method is recommended. Nevertheless, when literacy or motivation of participants is low, the 24hR might be applied as the reference measure of nutrient intake (6) .In an earlier study, an FFQ was developed for use in pregnant women ...

“…The 85-food-item-FFQ was previously designed for Brazilian pregnant women living in Ribeirã o Preto, São Paulo state. 27 It includes four options of portion size and takes the confirmed date of pregnancy as the time reference. The reproducibility of the FFQ was tested in a previous study conducted among 95 pregnant women.…”

BACKGROUND/OBJECTIVES:To assess the performance of a food frequency questionnaire (FFQ) for estimating o-3, o-6 and trans fatty acid intake during pregnancy. Moreover, we determined whether the fatty acid composition of mature breast milk represents a valuable biomarker for fatty acid intake during pregnancy. SUBJECTS/METHODS: A prospective study in 41 pregnant women, aged 18-35 years, was conducted. Food intake during pregnancy was evaluated by three 24-h recalls (24 hR), and 2 FFQ. The fatty acid composition of mature breast milk was determined by gas chromatography. The method of triads and joint classification between quartiles of intake were applied. RESULTS: The FFQ was accurate for estimating docosahexanoic (DHA), linoleic and total o-6 fatty acids according to validity coefficients. Higher agreements (470%) into the same or adjacent quartiles between the dietary methods were found for a-linolenic, total o-3, linoleic and trans fatty acid intake. High validity coefficients for eicosapentanoic (EPA) and DHA acids of human milk were found (0.61 and 0.73, respectively), and the method was adequate for categorizing the intake of a-linolenic, total o-3 and trans fatty acids compared with FFQ estimates, and for arachidonic acid and trans fatty acids compared with food recall estimates, during pregnancy. CONCLUSIONS: The FFQ was an accurate tool for categorizing a-linolenic, total o-3 and trans fatty acid intake. According to the validity coefficients observed, the FFQ accurately estimated DHA, linoleic and total o-6 fatty acids and the composition of mature breast milk was shown to be a suitable biomarker for EPA and DHA fatty acid intake during pregnancy.

“…Jensen 28 argues that 300mg/day of DHA may increase the amount of this fatty acid in human milk. It is noteworthy that Brazilian women do not have the habit of consuming fish twice a week, which would help them to meet their DHA requirement 45 .…”

Supplementation with the omega-3 docosahexaenoic acid: influence on the lipid composition and fatty acid profile of human milk

et al. 2013

OBJECTIVE: This study assessed the impact of supplementing the diet of women during pregnancy and lactation with fish oil containing the omega-3 fatty acid docosahexaenoic acid, and its influence on the composition of human milk. METHODS: The sample comprised 60 women aged 18 to 38 years with appropriate dietary pattern, all of them healthy and nonsmokers. The intervention consisted of a daily supplementation with fish oil capsules that corresponded to a daily intake of 315mg of docosahexaenoic acid and 80mg of eicosapentaenoic acid during the third trimester of pregnancy and the first three months postpartum. The total fat content and fatty acid profile of their milk were determined by creamatocrit and gas chromatography. Descriptive statistics were used for data analysis and the significance level was set at p<0.05. RESULTS: There was no statistical difference between the fat contents of the study (fish oil capsules) and control (capsules containing corn starch as filler) groups. However, the milk of women taking fish oil contained higher docosahexaenoic and eicosapentaenoic acid levels 30 and 60 days after delivery. These results demonstrate that high omega-3 intake can influence its concentration in human milk. CONCLUSIONS: Given the importance of docosahexaenoic acid in the neonatal period, it is appropriate for pregnant and breastfeeding women to supplement on long-chain polyunsaturated fatty acids, which may be done by adding fish oil to the regular diet.
