Abstract

MARANHAO NETO, Geraldo Albuquerque; POLITO, Marcos Doederlein  and  LIRA, Vitor Agnew. Reliability between reported and measured weight and height, and influence of physical activity history on individuals who search for supervised practice of exercises. Rev Bras Med Esporte [online]. 2005, vol.11, n.2, pp. 141-145. ISSN 1517-8692.  http://dx.doi.org/10.1590/S1517-86922005000200009.

The objective of this study was to verify the reliability between self-reported and measured weight, height and body mass index values, as well as the influence of the physical activity history on 328 individuals, 200 women (39 ± 11 years) and 128 men (35 ± 10 years) who search for the supervised practice of exercises. All individuals underwent functional evaluation that recorded self-reported and measured weight and height values. The individuals were also classified as active (those who exercised three times a week or more), a low active (those who exercised from one to two times a week), and inactive (those who did not exercise), according to the physical activity history in the last three months previously to the evaluation. The data obtained through the calculation of the intraclass correlation coefficient showed high reliability between variables reported in men (ICC > 0.94) and women (ICC > 0.96). The one-way analysis of variance ANOVA did not suggest any association, either isolated or combined, between the physical activities review and regularity in the error magnitude in reports from men (p > 0.29) and women (p > 0.07). According to these findings, the authors encourage weight and height report use in studies with large sampling size, regardless the physical activity level.
