“…The use of three measures has proved more efficient for the triangulation of Na intake (29,30) . Another contribution of the present study was the inclusion of low-income individuals of marginal literacy, as such people tend to face greater difficulty in filling out questionnaires (11) .…”

Objective: To assess the reliability and validity of an FFQ to evaluate dietary patterns of Na consumption among low-income and low-literacy Brazilian hypertensive subjects. Design: The initial FFQ was submitted to content analysis with the pre-test administered to fifteen subjects. Reliability was evaluated according to the reproducibility criterion, with interviewer administration of the FFQ twice within a 15 d interval. Validity was assessed against a 24 h recall (132 subjects), a 3 d diet record (121 subjects) and a biomarker (24 h urinary Na; 121 subjects). To test the correlation with the biomarker, discretionary salt was added to the FFQ Na values. Setting: A large urban teaching hospital in south-eastern Brazil. Subjects: The study was based on 132 randomly selected subjects (eighty-three women and forty-nine men) aged 18 to 85 years. Results: Kappa coefficients ranged from 0?79 to 0?98, confirming the reproducibility of the FFQ. There was no correlation between urinary Na excretion, the FFQ and the 24 h recall for the general sample, although significant correlations had been observed when methods were summed up (24 h recall 1 discretionary salt 1 FFQ; 0?32, P 5 0?01). The addition of discretionary salt significantly improved the biomarker-based FFQ validity, with correlation coefficients varying from 0?19 (general sample) to 0?31 (female sub-sample). Conclusions:The developed FFQ demonstrated satisfactory evidence of validity and reliability and can be used as an important complementary tool for the evaluation of Na intake among Brazilian hypertensive subjects.

“…Three per cent of respondents did not know which method they preferred or felt there was no difference (9,10) . Respondents preferred the food checklist because it was easier than the other methods (49 %) and respondents did not have to do the recording themselves (as it was already written down for them; 26 %).…”

“…The weighed inventory, although it did not score highly and showed distinct disadvantages with problems relating to language, literacy and numeracy, was recommended as a reference method to provide information on the relative validity of the test methods and for comparisons with previous NDNS. These four methods were used in the subsequent method comparison study -the Low Income Diet Methods Study (LIDMS), the study design and initial findings of which have been reported elsewhere (9,10) . Briefly, LIDMS was carried out in 2001 and involved a crosssectional design, comparing three 4 d dietary survey methods (multiple-pass 24 h recall, food checklist and semi-weighed method) against reference measures in respondents living on a low income in London.…”

“…The rationale for changes in ranks as a result of the present review is given in the Results section. Scores for each method were recalculated as the sum of the revised ranks.In addition to the review of the original list of factors considered in the Scoping study, further methodological evaluative outcomes from the LIDMS study were introduced in the form of ten new factors not previously considered (11) . Methodological strengths and weaknesses were considered against these new factors and each method was ranked using the same system as that used in the Scoping study.…”

In 1998, a review for the Ministry of Agriculture Fisheries and Food (the predecessor of the Food Standards Agency) was published evaluating the relative merits of different dietary assessment methods against a series of factors likely to affect compliance or accuracy in low-income households. The review informed the design of a method comparison study carried out in London, UK, in 2001, in which the validity and acceptability of 4 d dietary assessment methods based on 24 h recalls, food checklists and a semi-weighed method were compared with 4 d weighed inventories and other reference measures. Results were based on observations in 384 respondents (159 males, 225 females) aged 2-90 years in 240 households. Outcomes of the comparison study included evaluations of each method made by respondents, interviewers and researchers. These findings were used in the present paper to update and extend the 1998 review. Additional factors not included in the 1998 review have been considered. This updated and extended review provides the basis for discussion of the relative merits of approaches to dietary assessment in low-income households in developed economies. The evidence presented here and elsewhere suggests that the 24 h recall is the method best suited for dietary assessment in low-income households, followed by the weighed inventory, food checklist and lastly the semi-weighed method. Keywords Review Low income Strengths Weaknesses Dietary surveyIn 1997, the Ministry of Agriculture, Fisheries and Food (the predecessor of the Food Standards Agency (FSA)) commissioned a critical review of dietary assessment methods for use in people living on low income, published as a 'Scoping study ' in 1998 (1) . The report critically reviewed the applicability, feasibility and cost of seven different dietary assessment methods in terms of their appropriateness for a dietary survey of people living on low income in the UK. The dietary assessment methods reviewed were the weighed inventory, the household measures technique, the semi-weighed method (2) , the food checklist, the diet history, the 24 h recall and the FFQ.Methodological strengths and weaknesses were considered and each method was rated using a simple ranking system. Each method was assigned a rank (11, 0, 21) in relation to sixteen factors believed by the authors to be important for consideration in low-income households (1) . The authors assigned ranks based on their own experience and reading of the literature. The ranks were assigned as follows: 11 if there was deemed to be a distinct positive advantage relating to the use of the method in low-income households; 0 if the method was deemed to have no distinct advantage or disadvantage; 21 if there was deemed to be a distinct disadvantage relating to the use of the method in low-income households. The individual ranks were then summed to create a score for each method ('Total 1'), as published in the original Scoping study, shown in Table 1. The scoring was intended to capture a cumulative impression of the rela...

“…Third, existing evidence relating dietary intake to vitamin D status is often limited due to imprecise dietary assessment methods, such as single 24-hr recall or Food Frequency Questionnaires (FFQ) [21][22][23][24][25]. Single 24-hr dietary recalls cannot account for intra-individual dietary variations that occur over time.…”
