[Trends in the frequency of obesity and gestational diabetes in an eleven years period]. / Evaluación de la tendencia de diabetes gestacional en un período de 11 años en Buenos Aires, Argentina.

BACKGROUND: The prevalence of gestational diabetes (GDM) is increasing along with obesity and gestational age. This prevalence varies in populations and with different guidelines used for the diagnoses. AIM: To estimate the change in prevalence of GDM and obesity in a period 11 years. MATERIAL AND METHODS: Analysis of pregnancies attended at an obstetrics ward of a general hospital between 2001 and 2018. Those women who were diabetic prior to their pregnancy were excluded from the analysis. Annual crude and adjusted prevalence using direct standardization by age were estimated. RESULTS: We analyzed 33,985 pregnancies. GDM screening was performed in 20,139 (59%), and 1,466 (7%) had GDM. In 2007 the crude and adjusted prevalence of GDM were 4.9 and 5.2%, respectively. The figures in 2018 were 8.8 and 8.5%, respectively, with an annual percentage of change (APC) of 6.9% (p < 0.001). The frequency of obesity also increased with an APC of 4.1% (p < 0.001). In women with GDM the APC of obesity was 4.6% (p < 0.001). There was also an increase in the frequency of screening, with a joinpoint in 2011. The APC of screening in the periods 2007-2011 and 2011-2018 were 16.6 and 2.9%, respectively (p < 0.001). CONCLUSIONS: The prevalence of GDM increased in this period of eleven years along with the prevalence of obesity.

[Gestational diabetes mellitus in a hospital in the city of Buenos Aires, Argentina: incidence, treatment, and frequency of screening for reclassification after childbirth] / Diabetes mellitus gestacional en un hospital de la Ciudad de Buenos Aires, Argentina: incidencia, tratamiento, y frecuencia de tamizaje para reclasificación luego del parto

Introduction: Gestational diabetes mellitus (GDM) is defined as glucose intolerance diagnosed during pregnancy. This pathology can be associated with maternal and feto-neonatal complications, both in the short and long term. The prevalence of GDM in Argentina (based on the diagnostic criteria of the Latin American Diabetes Association (ALAD), is estimated between 7.5-10% of pregnant women. Information in Argentina on the incidence of GDM is scarce. The objective of this work was to estimate the incidence of GDM, evaluate its treatment and the frequency of screening for postpartum reclassification of diabetes in a population of pregnant women treated at a private hospital in the city of Buenos Aires. Materials and methods: Retrospective cohort of pregnant women evaluated at the Hospital Italiano de Buenos Aires, Argentina between 2015 and 2018. Results: The cumulative incidence of GDM was 7.6% (95% CI 7.0-8, two). All patients received nutritional advice (food plan). Of the total number of pregnant women studied 229 (39.3%) required pharmacological treatment; Of these, 97 patients received insulin (16.7%) and 132 metformin (22.7%). Regarding the follow-up of the pathology, between six weeks and one year postpartum, 267 women (45.9%) underwent diabetes screening for reclassification. Screening frequency was higher in the insulin-treated group. Of the patients who underwent screening, 36 women (13.5%) had impaired fasting blood glucose, 16 women (6.0%) had impaired glucose tolerance, and 3 women (1.1%) were diagnosed with type 2 diabetes mellitus. two.Of these, 36 women (13.5%) had impaired fasting blood glucose, 16 women (6.0%) had impaired glucose tolerance, and 3 women (1.1%) were diagnosed with type 2 diabetes mellitus. Conclusion: GDM incidence was 7.6%. Less than half of the women diagnosed with GDM required pharmacological treatment. The frequency of diabetes screening up to one year postpartum for reclassification was similar to that reported.

Introducción: La diabetes mellitus gestacional (DMG) se define como la intolerancia a la glucosa diagnosticada en el embarazo. Esta patología puede asociarse a complicaciones maternas y feto-neonatales, tanto a corto como a largo plazo. La prevalencia de DMG en Argentina (basada en el criterio diagnóstico de la Asociación Latinoamericana de Diabetes (ALAD), se estima entre 7,5-10% de las mujeres embarazadas.  Es escasa la información en Argentina sobre la incidencia de DMG. El objetivo de este trabajo fue estimar la incidencia de DMG, evaluar su tratamiento y la frecuencia de tamizaje para reclasificación postparto de la diabetes en una población de mujeres embarazadas atendidas en un hospital privado de la ciudad de Buenos Aires. Materiales y métodos: cohorte retrospectiva de embarazadas evaluadas en el Hospital Italiano de Buenos Aires, Argentina entre los años 2015 a 2018. Resultados: La incidencia acumulada de DMG fue 7,6 % (IC 95% 7,0-8,2). Todas las pacientes recibieron consejo nutricional (plan alimentario). Del total de embarazadas estudiadas requirieron tratamiento farmacológico 229 (39.3%); recibieron insulina 97 (16,7%) y 132 metformina (22,7%). En cuanto al seguimiento de la patología, entre las seis semanas y el año postparto realizaron tamizaje de diabetes para reclasificación 267 mujeres (45,9%). La frecuencia de tamizaje fue mayor en el grupo tratado con insulina. De las pacientes que realizaron el tamizaje, presentaron glucemia alterada en ayuno 36 mujeres (13,5%), tolerancia a la glucosa alterada 16 mujeres (6,0%) y 3 mujeres (1,1%) fueron diagnosticadas con diabetes mellitus tipo 2. Conclusión: la incidencia de DMG fue 7,6%. Menos de la mitad de las mujeres diagnosticadas con DMG requirió tratamiento farmacológico. La frecuencia de tamizaje de diabetes hasta el año postparto para la reclasificación similar a la reportada.

Incidencia de recién nacidos grandes para la edad gestacional y su asociación con diabetes mellitus gestacional y obesidad maternas. Estudio de cohorte en un hospital de Buenos Aires / Incidence of large-for-gestational-age newborns and its association with maternal gestational diabetes mellitus and obesity. Cohort study in a hospital in Buenos Aires

Resumen Introducción: existen dos términos para describir el crecimiento fetal excesivo: "grande para la edad gestacional" (GEG) y "macrosomía". GEG generalmente implica un peso al nacer superior al percentil 90 para una edad gestacional determinada. Objetivos: estimar la incidencia de recién nacidos GEG, y evaluar si la obesidad y la diabetes mellitus gestacional (DMG) son factores asociados. Materiales y métodos: estudio de cohorte retrospectivo de embarazadas -con y sin DMG- y sus recién nacidos vivos entre 2015 y 2018, evaluadas en el Hospital Italiano de la Ciudad Autónoma de Buenos Aires. La incidencia de recién nacidos GEG y de macrosomía se presentó como porcentajes e intervalos de confianza del 95% (IC 95%), así como sus complicaciones. Se utilizó regresión logística múltiple para evaluar si la DMG y la obesidad eran factores asociados a recién nacidos GEG. Resultados: la incidencia de GEG fue del 15,9% (IC 95%; 14,117,9) y de macrosomía del 6,7% (IC 95%; 5,5-8,1). La incidencia de recién nacidos GEG fue mayor en las mujeres con DMG y obesidad. La obesidad representó per se un mayor riesgo con y sin asociación con DMG. La obesidad, en presencia de DMG, incrementa la chance de recién nacidos GEG comparada con las mujeres sin DMG y sin obesidad (OR 2,41; p<0,001). Conclusiones: la DM y la obesidad materna incrementan el riesgo de GEG. Es importante implementar medidas preventivas e intervenciones en las mujeres en edad fértil con el objetivo de promover la salud de la madre y de su descendencia.

Abstract Introduction:two terms are used to describe excessive fetal growth: "large for gestational age" (LGA) and "macrosomia". LGA generally implies a birth weight greater than the 90th percentile for a given gestational age. Objectives: to estimate the incidence of LGA newborns and to assess whether obesity and gestational diabetes mellitus (GDM) are associated factors. Materials and methods: retrospective cohort study of pregnant women with and without GDM and their live newborns between 2015-2018 evaluated at the Italian Hospital in the City of Buenos Aires, Argentina. The incidence of LGA and macrosomia newborns is presented as percentages and 95% confidence intervals (95% CI), as well as their complications. Multiple logistic regression was used to assess whether GDM and obesity are factors associated with LGA newborns. Results: the incidence of LGA was 15.9% (IC 95%; 14.1-17.9) and of macrosomia 6.7% (IC 95%; 5.5-8.1). The incidence of LGA newborns was higher in women with GDM and obesity. Obesity represented a higher risk per se with and without association with GDM. Obesity, in the presence of GDM, increases the chance of LGA newborns compared to women with GDM and without obesity (OR 2.41; p<0.001). Conclusions:diabetes and maternal obesity increase the risk of LGA. It is important to implement preventive measures and interventions on women of childbearing age with the aim of promoting the health of the mother and her offspring.
