Food Frequency Questionnaire (FFQ) is a commonly used tool for the measurement of food intake of a large population. However, FFQ could be influenced by the cultures, seasons and food habits. Thus FFQ should be validated against a known or standard tool like a multiple 24-hour dietary recalls (24h) and also needs to be tested for its reproducibility. Hence, in this study, the reproducibility of a Raw food based quantitative FFQ (RFFQ) was assessed and validated against the standard multiple 24h method. A community-based longitudinal study was conducted among 106 urban adult subjects in Hyderabad Metropolitan city of South India. The reproducibility of RFFQ was assessed at two reference periods of a year and seasonal variation was investigated across three seasons. Further, RFFQ was validated against 24h across three seasons of the year. The median and Inter Quartile Range (IQR) of food and nutrient intakes have shown that the RFFQ was comparable to 24h of four months duration and also between baseline and final RFFQs. No significant seasonal difference in food and nutrient intake was observed by the RFFQs (p>0.05). Bland-Altman analysis showed an agreement between the RFFQ and 24h indicating relative validity of the RFFQ in the study population. The reproducibility of the RFFQs was found to be good as observed by Intra class Correlation Coefficients (ICC). The RFFQ of one year duration is thus a valid tool to elicit long-term habitual dietary intake pattern of urban adult subjects in South India. As the RFFQ used in this study is raw food based it could be adopted to other parts of the country.

Abstract Background Food frequency questionnaires are considered an effective method for assessing habitual dietary intake, but they must be developed or validated with the target population. Portion size, supplement use and food choice are thought to be especially important methodological considerations for assessing athletes’ dietary intake. This study aimed to develop and validate a food frequency questionnaire for Japanese athletes using data from this population. Methods We used dietary records from 440 Japanese athletes involved in our previous projects. Food items were analyzed using cumulative percentage contributions and multiple regression analysis, to give a selection of 62 basic food items and four supplemental items. The validity of the questionnaire was evaluated among another 77 Japanese athletes by comparing nutrient intakes assessed using the questionnaire with dietary records. Reproducibility was evaluated by comparing a second questionnaire completed 2–3 weeks later by 36 of the athletes in the validation study. Validity was assessed using crude Spearman’s correlation coefficients (CCs), energy-adjusted CCs, intraclass CCs (ICCs), and Kappa index values. Reproducibility was assessed by CCs, energy-adjusted CCs, and ICCs. Results In the validation analysis, the median crude CC for all of the nutrients was 0.407, ranging from 0.222 for dietary fiber to 0.550 for carbohydrate. The median energy-adjusted CC was 0.478, and the median ICC was 0.369. When we divided the athletes into quartiles, 65% (vitamin B1) to 86% (iron) of athletes were classified into the same or adjacent categories using the questionnaire and dietary records, with a median Kappa statistic of 0.32. In the reproducibility analysis, the median crude CC between the two completed questionnaires was 0.654, ranging from 0.582 (carbohydrate) to 0.743 (vitamin B2). The median energy-adjusted CC was 0.643, and the median ICC was 0.647. Conclusions The new 62-item food frequency questionnaire is both reliable and valid and may be useful for assessing food intake in Japanese athletes.
