<b> Are self-reported measures valid for the assessment of nutritional status in the brazilian population? </b>

Abstract

Self-reported measures have been widely used for the assessment of nutritional status in epidemiological studies. This paper discusses aspects regarding the validity of self-reported measures of body weight and height for the assessment of nutritional statusin Brazilian children, adolescents, adults and elderly subjects. The available evidence suggests that: a) in children, the use of self-reported measures is not recommended because of the lack of Brazilian studies; b) in adolescents, these measures should be used with caution since the only study carried out in Brazil was restricted to a local sample and may not represent the situation in other regions; c) in adults, this method can be considereda viable alternative for assessing and monitoring nutritional status in situations in which these data cannot be measured directly; d) in the elderly, the use of self-reported measures cannot yet be recommended for two reasons: first, studies specifically includingsubjects older than 60 years have not been conducted and, second, this age group tends to estimate these measures less accurately.
