    <p><strong>Abstract: </strong></p><p><strong>Background: </strong>Gestational diabetes mellitus (GDM) refers to diabetes diagnosed in the second or third trimester of pregnancy. Assessing the weight gain in each pregnant women's appointment is a common task of primary care during their visit. However, the implications of this increase in weight for the development of GDM are unknown.</p><p><strong>Objective: </strong></p><p> Evaluate if the greater than expected weight gain (HEWG) in pregnancy is a risk factor for the development of GDM.</p><p><strong>Methods:</strong></p><p> Analytical, observational, longitudinal, retrolective study, which included pregnant women between 15 and 40 years of age with complete follow-up of the pregnancy with > 2 prenatal check-ups, somatometry and complete medical history was made. During follow-up, the GPME was determined. Odds ratio (OR) and 95% confidence intervals (95% CI) were calculated. Variables with significance were entered into a multiple logistic regression model (MLR), where the dependent variable was DMG. The sample size calculation was for convenience.</p><p><strong>Results:</strong> 1000 pregnant women with a median age of 28 years were included. In the MLR The pre-gestational body mass index (BMI) with overweight had an RM of 1.3 (95% CI 0.86-1.98), BMI with obesity an OR of 2.57 (95% CI 1.6-4.14), the HEWG during pregnancy had an OR 1.14 95% CI (0.71-1.81), Age> 30 years shows an RM of 2.24 (95% CI 1.55-3.25).</p><p><strong>Conclusions:</strong> HEWG during pregnancy is not an independent risk factor for the development of GDM. The main ones are age> 30 years and pre-gestational obesity.</p><p><strong>Introducci贸n: </strong>la diabetes mellitus gestacional (DMG) se refiere a la diabetes diagnosticada a partir del segundo trimestre del embarazo. Evaluar el incremento de peso de mujeres embarazadas es una labor habitual en la consulta del primer nivel de atenci贸n. Sin embargo, se desconocen las implicaciones que tiene este incremento ponderal para el desarrollo de DMG.</p><p><strong>Objetivo:</strong> evaluar si la ganancia ponderal mayor a la esperada (GPME) en el embarazo es factor de riesgo para el desarrollo de DMG. </p><p><strong>M茅todos:</strong> estudio anal铆tico, observacional, longitudinal, retrolectivo, que incluy贸 a embarazadas de 15 a 40 a帽os con seguimiento completo del embarazo con m谩s de dos consultas de control prenatal, somatometr铆a e historia cl铆nica completa. Durante el seguimiento se determin贸 la GPME. Se calcul贸 raz贸n de momios (RM) e intervalos de confianza del 95% (IC95%). Las variables con significancia se ingresaron a un modelo de regresi贸n log铆stica m煤ltiple (RLM), en donde la variable de desenlace fue DMG. </p><p><strong>Resultados:</strong> se incluyeron a 1000 embarazadas con mediana de edad de 28 a帽os. En la RLM el 铆ndice de masa corporal (IMC) pre-gestacional con sobrepeso tuvo una RM de 1.3 (IC95%: 0.86-1.98), IMC con obesidad una RM de 2.57 (IC95%: 1.6-4.14), la GPME durante el embarazo tuvo una RM de 1.14 (IC95%: 0.71-1.81) y la edad > 30 a帽os una RM de 2.24 (IC95%: 1.55-3.25). </p><p><strong>Conclusiones:</strong> la GPME durante el embarazo no es un factor de riesgo independiente para el desarrollo de DMG. Los principales son la edad >30 a帽os y la obesidad pregestacional.</p&gt
