INTRODUCTION Several tools are available to clinicians for Weight gain during pregnancy is a complex phe- assessing nutritional status during pregnancy. These nomenon influenced by multiple physiological, include the guidelines proposed by the United placental and metabolic factors (1), one of the most States Institute of Medicine (IOM) (18), which important being nutritional status before pregnancy are currently the subject of debate because of the initiation (2, 3). weight gain parameters are considered too high for In the Americas and the Caribbean, the prevalence the Latin American population. Another option is of overweight and obesity among adult women is the Rosso-Mardones (RM) nomogram proposed in around 70% (4) and, according to the Colombian 1997, which identifies women at risk who require National Nutritional Status Survey (ENSIN, 2010), nutritional intervention (13, 16). According to the the prevalence for Colombia was 34% (5). But excess guidelines of the Colombian National Institute of weight and obesity are not the only factors affecting Health (INS), neonates with a birth weight between the course of gestation; according to the ENSIN, 2,500 and 2,999 g are classified as weight-deficient, one out of every five pregnant women, on average, while 3,000 g is classified as normal weight (19). 36 Revista Colombiana de Obstetricia y Ginecología Vol. 71 No. 1 • 2020 The RM nomogram has been used to predict that for grading nutritional status in pregnant women. women with low weight at the start of pregnancy The women enrolled were 19 years of age and older, are at a higher risk of bearing children weighing < with a gestational age of 10 or more weeks who at- 3.000 g (0.31 sensitivity and 0.8 specificity), while tended Clínica La Ermita in Cartagena (Colombia) women diagnosed as overweight or obese have a during the period between March and May, 2017. higher risk of bearing neonates with a birth weight Pregnant women with diabetes, thyroid disease, > 4.000 g (0.30 sensitivity and 0.77 specificity) (20, pregnancy-related hypertensive disorder and hydrops 21). The main drawback of the RM scale is that it fetalis were excluded. This Clinic is a private Level III can only be applied to women 140-175 cm tall and healthcare facility that serves a population consist- weighing between 30 and 100 kg (22). ing mainly of patients affiliated to the contributive Finally, according to Grandi, “the World Health regime of the Colombian General Social Security Organization (WHO) has proposed that nutritional System. Convenience sampling was carried out from assessment in pregnant women be performed using the universe of patients attending the participating BMI, obtained by dividing weight (kg) by height institution during the study period. Sample size was (m) square” (23); and Espinoza et al. point out that not calculated. “Body mass index (BMI) is an anthropometric way Procedure. Potential candidates were identified to define fat and lean mass composition in men and among pregnant women who presented to the women” (16). It was based on this premise that the emergency service and were later admitted to the scale proposed by Atalah (AEA) was developed in participating institution. Inclusion and exclusion 1997, which gives a theoretical definition of the criteria were then applied and the study subjects table using the normality criterion proposed by were selected. One of the investigators explained the Food and Agriculture Organization (FAO) (24). the study objectives and requested authorization However, the AEA proposal also has limitations for participation and then proceded to gather because, in pregnant women with short legs, information on sociodemographic and clinical BMI does not necessarily correlate with body fat variables. Weight and height were determined percentage and, during pregnancy, this ratio reflects using a mechanical Rice Lake scale with a capacity both maternal as well as fetal weight (2). for up to 200 kg and attached size meter. The Given these limitations of each of the nutritional nutritional status of each patient was determined assessment tools, and also given the fact that there in accordance with the RM and AEA models. The are no known studies in Colombia designed to two components of the RM model, a nomogram assess the degree of agreement between both these and a weight gain graph, are used to calculate weight tools which are widely used in our population, the percentage for height (W/H), based on the woman’s objective of this study is to assess concordance weight and height; this value is projected on the between the maternal nutritional status assessment percentage found in the nomogram, in relation model proposed by Atalah and the Rosso-Mardones to the gestational age at which the measurement nomogram in a population of pregnant women in is made (20). On the other hand, for the AEA the Caribbean region of Colombia.
