The Automated Self-Administered 24-Hour Dietary Recall for Children, 2012 Version, for Youth Aged 9 to 11 Years: A Validation Study

Abstract

Background Valid methods of diet assessment are important for nutrition research and practice but can be difficult with children. Objective To validate ASA24-Kids-2012, a self-administered web-based 24-hour dietary recall (24hDR) among 9-11-year-old children, in two sites. Design Quasi-experimental Participants/setting In one site, trained staff observed and recorded foods and drinks consumed by children (n=38) during school lunch. The next day, the observed children completed both ASA24-Kids-2012 and an interviewer-administered 24hDR in a randomized order. Procedures in a second site (n=31) were similar, except observations occurred during dinner in a community location. Statistical analyses Foods were classified as matches (reported and consumed), intrusions (reported, but not consumed), or omissions (not reported, but consumed) for each participant. Rates of matches, intrusions, and omissions were calculated. Rates were compared between each recall method using repeated measures analysis of covariance. For matched foods, the authors determined correlation coefficients between observed and reported serving sizes. Results Match, intrusion, and omission rates between ASA24-Kids-2012 and observed intakes in site 1 were 37%, 27%, and 35%, respectively. Comparable rates for interviewer-administered 24hDRs were 57%, 20%, and 23%, respectively. In site 2, match, intrusion, and omission rates between ASA24-Kids-2012 and observed intakes were 53%, 12%, and 36%, respectively, vs. 76% matches, 9% intrusions, and 15% omissions for interviewer-administered 24hDRs. The relationship strength between reported and observed serving sizes for matched foods was 0.18 in site 1 and 0.09 in site 2 for ASA24-Kids-2012, and 0.46 in site 1 and 0.11 in site 2 for interviewer-administered 24hDRs. Conclusions ASA24-Kids-2012 was less accurate than interviewer-administered 24hDRs when compared to observed intakes, but both performed poorly. Additional research should assess the age at which children can complete recalls without the help of a parent or guardian, as well as to elucidate under which circumstances recalls can reasonably be used among children.

Validity of WebCAAFE questionnaire for assessment of schoolchildren’s dietary compliance with Brazilian Food Guidelines

“…The findings of the present study add to previous WebCAAFE validation study results (22) and to other web-based 24 h recall/record validation studies in children using observation during school meals as a reference method (13,14,(16)(17)(18) .…”

“…In the present study, about a quarter of the children analysed were 7-8 years old, about 20 % had parents with at most elementary school education and a further 20 % had parents with high school education (Table 1). Compared with aforementioned validation studies regarding other web-based food questionnaires (13,14,18) , the social and educational background of the WebCAAFE respondents was considerably lower. The high percentage bias for fish/sea products, meats, fruits and beans may have occurred because the food images in the WebCAAFE screen for these items did not match the way children often eat (Fig.…”

“…The present study used Poisson regression regularly applied to count outcomes such as the number of food items consumed per day, with logarithmic transformation of the counts and population variance assumed to equal the mean consumption, both of which take into account the peculiarities of the measurement error structure in diet validation (32) . The WebCAAFE presents a different framework from other web-based questionnaires (11)(12)(13)(14)(15)(16)(17)(18)(19)(20) mainly because it was formulated as a previous-day recall of frequency of intake of thirty-two food items in each of six daily eating events, so the dietary assessment does not involve a fully quantified 24 h recall of foods and beverages. The cognitive task required for estimating portion size, frequency and averaging may not be compatible with the perceptual and conceptual capacities of children who have not reached the stage of abstract reasoning at approximately 10-11 years of age (26,27,29) .…”

Validade e reprodutibilidade de questionário baseado na Internet (Web-CAAFE) para avaliação do consumo alimentar de escolares de 7 a 15 anos

“…Nos últimos anos, foram desenvolvidos e validados diversos instrumentos computacionais de avaliação do consumo alimentar para crianças e adolescentes 1,2,3,4,5 .…”

“…Geralmente, instrumentos computacionais utilizam a técnica do recordatório do dia anterior ou 24 horas, dispõem de recursos audiovisuais para atrair a atenção do respondente e auxiliar seu processo cognitivo relacionado à memória para o relato dos alimentos 1,2,3,4,5 . Esses questionários são alternativas promissoras a serem empregadas em estudos populacionais, de monitoramento e no planejamento de políticas públicas.…”
