“…In the validation studies of dietary intake considered, quintiles were used in the calculation of kappa statistics (19,31) . The mean agreement % and the LOA %, sometimes regressed with the Bland-Altman plot (39,40) , were used in twelve studies (1,(13)(14)(15)(16)(18)(19)(20)24,27,29,31) . Since correct ranking ability is a desired outcome from an FFQ, nine studies ranked the subjects by using the same or adjacent tertile (1,13,15) , quartile (14,24,26) or quintile (17,19,31) per cent method.…”

Objective: The aim of the present work was to determine what dietary assessment method can provide a valid and accurate estimate of nutrient intake by comparison with the gold standard. Design: A MEDLINE, EMBASE, ISI Web of Science, Cochrane and related references literature review was conducted on dietary assessment methods for adolescents reporting the validity and/or reproducibility values. A study quality assessment on the retrieved FFQ was carried out according to two different scoring systems, judging respectively the quality of FFQ nutrition information and of FFQ validation and calibration. Setting: The present review considered adolescents attending high schools and recruited in hospitals or at home. Subjects: The target of the review was the healthy adolescent population in the age range 13-17 years. Results: Thirty-two eligible papers were included and analysed separately as 'original articles' (n 20) and 'reviews' (n 12). The majority (n 17) assessed the validation and reproducibility of FFQ. Almost all studies found the questionnaires to be valid and reproducible (r . 0?4), except for some food groups and nutrients. Different design and validation issues were highlighted, such as portion-size estimation, number of food items and statistics used. Conclusions: The present review offers new insights in relation to the characteristics of assessment methods for dietary intake in adolescents. Further meta-analysis is required although the current review provides important indications on the development of a new FFQ, addressing the need for a valid, reproducible, userfriendly, cost-effective method of accurately assessing nutrient intakes in adolescents. Keywords Dietary assessment Adolescents Validation ReproducibilityAdolescence is a critical period that is characterized by cognitive, emotional and social development and exposure to a significant turnover in lifestyle, including food intake and diet habits. Irregular meals, snacking and meal skipping, which characterize teenagers, often do not allow an accurate dietary assessment (1) and therefore the need to develop valid and reproducible instruments for this purpose is increasing. Different dietary assessment methods among adolescents have been extensively described and validated, such as food records (FR), FFQ, diet histories (DH) and 24 h recalls (24-HR). The FR is not used in large population studies for several reasons (2) : it can be quite expensive; it requires the participant to be literate and motivated; it involves trained staff; and it needs a computerized program specific to recording diet records. Thus, the FR is preferably used at the individual level and is generally considered a good reference instrument against which to validate other dietary methods to be used at the large population level, together with biomarker measurements (3) . The most used dietary assessment methods for large-scale surveys are therefore FFQ, 24-HR and DH, which present advantages such as cost-effectiveness, although they are affected by weaknesses (4,5) ...

“…The accurate assessment of nutritional intake is important in epidemiological studies. Although under-reporting of energy intake in young people has been shown (7) , the FFQ is feasible for this purpose (8) , considering the circumstances of young people that prohibit them from weighing foods, such as school attendance, as well as their ability to meticulously record food intake.Thus far, various FFQ have been assessed to determine their validity for use in young people in Western countries (9)(10)(11)(12)(13)(14)(15)(16) . To our knowledge, however, no study has determined the effectiveness of an FFQ in acquiring information on the diets of young people in Japan.…”

Objective: To assess the validity and reproducibility of a self-administered FFQ with eighty-two food items (FFQW82) for assessing the habitual diet in female adolescents. Design: The validity of the FFQW82 for assessment of nutrient intake was evaluated by comparison with a 7 d weighed food record (7d-FRRI) reported as 'gold standard'. Reproducibility of the FFQW82 was assessed at an interval of 1 month (test-retest method). The first survey (FFQW82 and 7d-FRRI) was conducted in April 2007 and the second FFQW82 survey was conducted in May 2007. Daily consumption of energy from eleven food groups and nine nutrients were calculated from both instruments for breakfast, lunch, dinner and the whole day. Crude and energyadjusted Pearson correlation coefficients were calculated using log-transformed data. Setting: Middle school, Tokyo, Japan. Subjects: Female adolescents aged 12-13 years. Results: Sixty-three female adolescents completed both surveys. The relative difference between the energy intake calculated by the FFQW82 and the 7d-FRRI for the whole day, breakfast, lunch and dinner was 8 %, 10 %, 15 % and 10 %, respectively. As for validity, the correlation coefficient of total energy intake for the whole day was 0?31. The result for breakfast was relatively higher (0?59) compared with that for lunch (0?40) and dinner (0?32). For macronutrients, the energy-adjusted correlation coefficient ranged from 0?28 (carbohydrates) to 0?53 (protein). Reproducibility of total energy intake was 0?62 and ranged from 0?46 (fat) to 0?69 (carbohydrate) for macronutrients. Conclusions: These results suggest that the FFQW82 has proved to have some potential with regard to reproducibility among our study population. Keywords FFQ Validity Reproducibility Female adolescents Nutrition assessmentIn recent years, youth obesity (1,2) and lifestyle-related diseases (3)(4)(5) have increased significantly, as have problems related to a distorted body image (6) . The accurate assessment of nutritional intake is important in epidemiological studies. Although under-reporting of energy intake in young people has been shown (7) , the FFQ is feasible for this purpose (8) , considering the circumstances of young people that prohibit them from weighing foods, such as school attendance, as well as their ability to meticulously record food intake.Thus far, various FFQ have been assessed to determine their validity for use in young people in Western countries (9)(10)(11)(12)(13)(14)(15)(16) . To our knowledge, however, no study has determined the effectiveness of an FFQ in acquiring information on the diets of young people in Japan. Previously, we developed an FFQ with sixty-five food items (FFQW65) to be used in nutritional education for the prevention of diabetes (17) . This instrument assessed energy intake separately for breakfast, lunch and dinner in addition to intake for the entire day and was useful for nutritional education in adults. We reported on the assessment of the effect of nutritional education in a randomized controlled trial ...

“…The online survey may not be as representative and efficient as another conventional method, mainly when the targeted population constantly uses the Internet (Bargas-Avila et al, 2009;Stanton & Rogelberg, 2001;Bliven et al, 2001). The online survey offers a number of advantages that include the possibility to communicate with groups geographically dispersed, the potential for the internationalization of the study, and the optimization of the process to tabulate data (Matthys et al, 2007). Therefore, the characteristics of data collection via the Internet make the survey technically, financially, and practically viable (Matthys et al, 2007).…”
