Objective:

To assess the degree of agreement between the model for maternal nutritional assessment proposed by Rosso-Mardones and the one proposed by Atalah.

Materials and methods:

Diagnostic agreement study. Pregnant women between the ages of 19 and 37 years with a gestational age of 10 or more weeks were included; patients with diabetes, thyroid disease, pregnancy-associated hypertension, twin pregnancy, severe fetal malformation, fetal death and hydrops fetalis were excluded. Non-probabilistic sampling. Sociodemographic, obstetrical and nutritional status variables were measured.

Results:

Overall, 98 pregnant women were included. With the use of the Rosso-Mardones scale, 33% of the patients were classified as having a normal nutritional status, 22% as low weight, and 44% as overweight or obese. With the Atalah scale, 41% of the women were classified as having a normal nutritional status, 10% as low weight and 48% as overweight or obese. The weighted kappa value was 0.74 with a standard error of 0.04, a 95% CI of 0.66-0.82 and a p value < 0.05.

Conclusions:

There is substantial agreement between nutritional assessment scales used in pregnancy, namely the Rosso-Mardones nomogram and the Atalah scale. Further studies to assess the agreement of these scales in the pregnant population are required.
