It is commonly assumed in public health practice that households in developing country settings are relatively homogeneous with respect to nutritional status. To the extent that this assumption is valid, nutritional assessments of mothers or individual children would provide an effective screening mechanism for household-level maternal-child nutritional risk. However, there has been no confirmation of the strength of intra-household correlations in nutritional status among women and children. Using data from a cross-sectional survey undertaken in 1990 in rural central Guinea, the present study investigates the nature of within-household relationships in maternal and child nutritional status and considers the implications for programme screening strategies. Mothers and their surviving children under 5 years of age are the focus of the analysis. Correlations between maternal and child nutritional levels are assessed and the performance of maternal-child nutritional indicators as screening tools for household nutritional risk are formally evaluated by analysing the sensitivity, specificity, and positive-negative predictive values of various indicators.
