Malnutrition and morbidity have a synergistic association that often leads to death.
However, malnutrition in children who die is largely underreported, because anthropometry of the deceased child is rarely known.
This study had two purposes :
I) to develop a scale that would help determine if a child had low weight-for-age (w/a), in the absence of anthropometric measures ; and ii) to select an appropriate cut-off that would give the best sensitivity (Se) and specificity (Sp) of the proposed scale when contrasted with actual w/a measurement.
The study was designed as a diagnostic test, and carried out in a rural area in central Mexico.
We included 132 children under 5 y old with w/a under - 2 Z score and 284 children with marginal or no w/a deficit as a control group.
The proposed scale included potential predictive variables from clinical, socioeconomic and family factors.
The best logistic regression model to predict low w/a included : birth weight less than 2,800 g, introduction of weaning foods after the sixth month of life, introduction of animal protein after the sixth month of life, low socioeconomic status, low w/a in siblings and more than three morbidity episodes in the previous 6 mon.
Selecting a cut-off of 4 for this model to identify children with low w/a showed a Se and Sp of 85 and 95%, respectively.
We tested the external validity of the scale in a different locale, and included 877 children under 5 y old from 10 rural communities. (...)
