Abstract

This study aimed to assess the agreement between measured and self-reported height and weight measures in 632 adults. The agreement was calculated using an intra-class correlation coefficient (estimated by ANOVA using one classification criterion), mean differences and agreement limits, according to Bland and Altman. The intra-category agreement of the nutritional status was assessed by Kappa statistics. In men, ICCs were 0.926 (95%CI: 0.894-0.959) and 0.873 (95%CI: 0.799-0.946), for weight and height measures, respectively, with the following mean difference and agreement limits for BMI: 0.143kg/m² (-2.844-3.129). In women, ICCs were 0.981 (95%CI: 0.973-0.988) and 0.794 (95%CI: 0.687-0.900) respectively, with the following mean difference and agreement limits for BMI: 0.462kg/m² (-2.457-3.382). Kappa coefficients for nutritional status in men and women were, respectively, 0.777 (95%CI: 0.683-0.872) and 0.793 (95%CI: 0.725-0.862). Self-reported measures are appropriate alternatives to classify nutritional status in epidemiological studies. (AU)
