The aim of this study was to compare a participatory nutrition status assessment procedure carried out by community members with an assessment completed by a professional. The study validated women (15--50 years of age) dietary intake assessments and assessed the reliability of anthropometric assessments of preschool (12--71 months) children in the hands of non-professionals. The prevalence of under-nutrition was similar for the two data sets and reliability of anthropometric measurements was found to be good except for the mid-upper-arm circumference measurement for which the difference between measurements of the professional and the nonprofessional and between two occasions differed significantly (p < 0.001). Results suggest that participatory nutrition status assessment procedure by community members is useful and fairly reliable, giving results similar to a procedure administered by a professional for some anthropometric indices. The correlation between a semi-quantitative food frequency questionnaire administered by community members and a series of three 24-h recalls administered by a professional for assessing the risk of inadequate intake was found to be weak for vitamin A and protein but moderate for iron. Spearman's rank correlation coefficients between the mean of three 24-h recalls values and semi-quantitative food frequency questionnaire estimates were 0.47 (p < 0.05) for iron, 0.29 (p < 0.05) for protein and 0.26 (p < 0.05) for vitamin A. The questionnaire produced results showing significantly higher intake estimates of protein (p < 0.001), vitamin A (p < 0.001) and iron (p < 0.01) than the average of three 24-hour recalls.
