“…In that study, 4.0% of the newborn weighings and 6.8% of the weighings in the longitudinal component of the study had to be repeated due to a difference between examiners that was greater than 100g. 2 In comparison, in our study only 1 (3%) infant had a difference of 100g between the weighing techniques, and none had any greater difference. This suggests that the loss of accuracy due to weighing the infant with the diaper on is not larger than the imprecision of the standard weighing technique.…”

Acurácia da pesagem de lactentes com a fralda na atenção primária à saúde Objetivo: estimar o viés introduzido pela pesagem de lactentes com fralda na atenção primária à saúde. Métodos: recrutamos lactentes que estavam para ser pesados numa unidade básica de saúde e pesamos cada lactente duas vezes: uma sem fralda, e outra com fralda, depois de a balança ter sido tarada com uma fralda seca. O viés foi calculado como a diferença percentual de peso, subtraindo o peso sem fralda do peso com fralda, e então dividindo o resultado pelo peso sem fralda. Resultados: recrutamos 30 lactentes entre os dias 23 de julho e 1º de agosto de 2013. A maioria estava lá para uma consulta médica agendada, e tinha tido sua fralda trocada havia menos de 45 minutos. A diferença percentual de peso média foi 0,3% (intervalo de confiança de 95%, 0,2% a 0,5%). Conclusão: houve concordância substancial entre as duas técnicas de pesagem. O viés (isto é, perda de acurácia) introduzido pela pesagem de lactentes com a fralda se compara favoravelmente à precisão da técnica padrão e à variabilidade fisiológica do peso dos lactentes. Pesar lactentes com a fralda parece ser uma técnica válida para a avaliação transversal do estado nutricional na atenção primária à saúde, apesar de mais pesquisa ser necessária antes de ela ser usada para a avaliação longitudinal da velocidade de ganho de peso.

Methods: we enrolled infants who were about to be weighed at a primary care center and weighed each infant twice -once without the diaper and once with the diaper on -after the scale had been tared with a dry diaper. The bias was calculated, as the percentage difference in weight, by first subtracting the no-diaper weight from the diaper-on weight and then dividing the result by the no-diaper weight. Results: we enrolled 30 infants from July 23 to August 1, 2013. Most infants were present for a scheduled medical doctor's visit, and their diapers had been changed less than 45 minutes before. The mean percentage difference in weight was 0.3% (95% confidence interval, 0.2% to 0.5%). Conclusion: we found a substantial agreement between the two weighing techniques. The bias (that is, loss of accuracy) introduced by weighing infants with the diaper on compared favorably with the precision of the standard technique and the physiological variability of the infants' weights. Our findings suggest that weighing infants with the diaper on may be a valid technique for the cross-sectional assessment of the nutritional status in primary health care settings. However, further research is needed before it is used for the longitudinal assessment of the weight velocity. Weighing infants with the diaper onRev Bras Med Fam Comunidade.

Objective: The study objective was to determine the relative validity and reproducibility of a modified FFQ for ranking the nutrient intakes of New Zealand toddlers aged 12-24 months. Design: Cross-sectional study. Setting: Dunedin, New Zealand. Subjects: One hundred and fifty-two participants completed a ninety-five-item FFQ twice, and five days of weighed diet recording (WDR), over one month. Validity and reproducibility were assessed for crude data and for data that were weighted for total fruit and vegetable intake (FV-adjusted). Results: De-attenuated correlations between FV-adjusted FFQ data and WDR data ranged from 0·45 (Zn) to 0·77 (Ca). The percentage classified to the correct WDR quartile by the FV-adjusted FFQ data ranged from 34·6 % (total fat, Zn) to 50·3 % (Fe). Average gross misclassification was 3 %. Bland-Altman statistics showed crude data had a range of 128-178 % agreement with the WDR and mean FVadjusted intakes had 112-160 % agreement. FV-adjusted intra-class correlations, assessing reproducibility, ranged from 0·65 (vitamin C) to 0·75 (Ca). Conclusions: The Eating Assessment in Toddlers (EAT) FFQ showed acceptable to good relative validity, and good reproducibility, for ranking participants' nutrient intake and is able to identify toddlers at extremes of the nutrient intake distribution. It will be a useful tool for investigating toddlers' nutrient intakes in studies that require a method of dietary assessment with low respondent burden.
