ABSTRACT

ANTECEDENTES: La obesidad en mujeres en edad reproductiva es cada vez más frecuente y complica el embarazo aumentando el riesgo de enfermedades como la diabetes mellitus gestacional (DMG). OBJETIVO: Determinar el riesgo de presentar DMG e intolerancia a la glucosa (ITG) de acuerdo con el índice de masa corporal pregestacional (IMCPG). MÉTODO: Muestra de 489 pacientes, se clasificaron por IMCPG y se les realizó una curva de tolerancia oral a la glucosa (CTOG) de 100 g de 120 minutos. Se definió DMG con dos valores alterados en la CTOG e ITG con un solo valor alterado. Se aplicó prueba de chi cuadrada para determinar diferencia entre grupos y se obtuvo un Odds Ratio (OR), con intervalo de confianza del 95%. RESULTADOS: 9 pacientes con bajo peso, 194 con peso normal, 158 con sobrepeso y 128 con obesidad, edad gestacional promedio 31,3 ± 5,6 semanas. El 13% de las pacientes presentaron DMG, el 10,6% ITG. Las mujeres con sobrepeso presentaron un OR de 3,81 para desarrollar ITG (IC95% 1,62-8,95) y un OR de 3,7 para DMG (IC95% 1,65-8,38), mientas que las pacientes con obesidad pregestacional presentaron un OR de 6,6 para desarrollar ITG (IC95% 2,83-15,66) y un OR de 8,8 para DMG (IC95% 4,05-19,51), comparadas con mujeres con peso pregestacional normal. CONCLUSIÓN: La población mexicana tiene mayor riesgo de DMG que otras poblaciones y mayor prevalencia de sobrepeso y obesidad, por lo que se debe realizar un diagnóstico y tratamiento oportuno de DMG, previniendo complicaciones y diabetes mellitus tipo 2.


BACKGROUND: Obesity in women in reproductive age is becoming more frequent and it self complicates preg-nancy increasing the risk of diseases such as gestational diabetes mellitus (GDM). AIMS: To determine the risk of gestational diabetes mellitus (GDM) and impaired glucose tolerance (IGT) according to the pregestational body mass index (PGBMI). METHODS: Sample of 489 patients, they were classified by PGBMI and underwent an oral glucose tolerance test (OGTT) with 100 g of glucose during 120 minutes. GDM was defined with two altered valúes in the OGTT and IGT with a single altered value. A chi-square test was applied to determine difference between groups, and we obtained an Odds Ratio (OR), with a confidence level of 95%. RESULTS: 9 patients were low weight, 194 normal weight, 158 overweight and 128 obese, average gestational age 31.3 ± 5.6 weeks. 13% of the patients had GDM, 10.6% had IGT. Overweight women had an OR of 3.81 of developing IGT (95% Cl 1.62-8.95) and an OR of 3.7 of developing GDM (95% Cl 1.65-8.38), while women with prepregnancy obesity showed an OR of 6.6 of developing ITG (95% Cl 2.83-15.66) and an OR of 8.8 of developing GDM (95% Cl 4.05-19.51), all compared to women with prepregnancy normal weight. CONCLUSIONS: Mexican population has a higher risk of GDM than other populations and also a higher prevalence of overweight and obesity, so that every pregnant woman should be screening for GDM, has a diagnosis and receive treatment, preventing complications and Type 2 Diabetes.
