Abstract

Objective: To analyze the reliability and validity of a food frequency questionnaire to assessfood consumption in South American children and adolescents.Methods: A sample of 200 children and 244 adolescents for the reliability analyses and 252children and 244 adolescents for the validity analyses, aged 3-18 years, from the SAYCARE study were included. Participants answered the food frequency questionnaire twice with a two week interval and three 24-hour dietary recalls. Spearman's correlations, weighted Cohen's kappa (kw), percentage of agreement and energy-adjusted Pearson's correlation coefficients were calculated.Results: The reliability analyses for children and adolescents resulted in Spearman'scoefficients ranging from 0.47 to 0.73, energy-adjusted Pearson's coefficients ranging from0.36 to 0.76, kw coefficients ranging from 0.35 to 0.63, and percentage of agreement between 72.75% and 83.52%. The validity analyses resulted in Spearman's coefficients ranging from 0.17 to 0.37, energy-adjusted Pearson's coefficients ranging from 0.17 to 0.61, kw coefficients ranging from 0.09 to 0.24, and percentages of agreement between 45.79% and 67.06%.Conclusion: The SAYCARE food frequency questionnaire presents satisfactory reliability and an acceptable validity for almost all food group intakes in children and adolescents.Keisyanne A Moura; Elsie C. de O.

This paper aims to test the validity of blood pressure measurement using an automatic oscillometric device (Omron HEM-7200), against the mercury column in children (n=191) and adolescents (n= 127) aged 3 to 18 years.Methods: The blood pressure will be measured by the Omron HEM-7200 automatic device, Yconnected with the mercury column, carried out three consecutive and simultaneous measurements between the devices. The independent measurements will be analyzed and the mean differences between systolic and diastolic measurements for both methods calculated and compared with the British Hypertension Society (BHS). To verify the validity of automatic monitor we used the Bland-Altman plot and limits of agreement 95% (95% LOA). The specificity and sensitivity of the device were determined by the ROC curve. The automatic monitor received the highest degree of BHS recommendations for systolic and diastolic blood pressures according to the BHS in both age groups.Results: The mean (95% LOA) difference between the observer and the monitor measurements were 1.4 (-9.9 ; 12.8)mmHg in children and 4.3 (-7.8 ; 16.5)mmHg in adolescents for systolic. For diastolic pressures were 2.2 (-7.4 ; 11.7)mmHg in children and 1.4 (8.4 ; 11.1)mmHg in adolescents.Conclusions: The monitor also satisfies the guidelines for the studied population. In conclusion, the Omron HEM-7200 monitor can be consider (AU)
