ABSTRACT
Abstract@#Women with gestational diabetes mellitus (GDM) during their pregnancy have a greater risk of developing overt diabetes mellitus and dysglycemia (prediabetes, impaired glucose tolerance or impaired fasting glucose) later in future, compared to mothers with normal pregnancy. Postpartum screening is crucial for early identification of type 2 diabetes (T2DM) in women with GDM. Nevertheless, despite various strategies, its rate remains low. A systematic review using databases of PubMed/Medline, Science Direct and CINAHL from 2008 to 2018, was conducted to identify the factors influencing the attendance of postpartum diabetes screening. Open access English articles, focusing on observational studies were reviewed. Primary screening of titles and abstracts of 91 articles were done, secondary screening of 31 articles resulted in 6 articles, included in this manuscript. Various factors identified to be associated with the attendance to postpartum diabetes screening, which are age, education, ethnicity, some obstetric factors like multiparty, and history of insulin usage previously. Many women fail to be screened for diabetes during the postpartum period, and this delays T2DM diagnosis, which in turn gives rise to various complications. Further research that considers these factors is necessary for developing interventions to improve postpartum T2DM screening for mothers with GDM during their pregnancy
ABSTRACT
Conocer la frecuencia de diabetes y otros factores de riesgo cardiovascular en mujeres con diabetes mellitus gestacional (DMG) previa. Se evaluaron 92 mujeres con DMG previa, a quienes no se les había diagnosticado diabetes, que asistieron a la pesquisa posparto inicial o anual durante 2008. Se determinó presión arterial, circunferencia abdominal (CA) e índice de masa corporal (IMC). Se practicó prueba de tolerancia oral a la glucosa, medición de niveles de insulina y lípidos séricos. Se estableció la presencia de síndrome metabólico (SM), aplicando los criterios ATP III e índice de resistencia a la insulina mediante el modelo Homa-R. Se usó t Student para la asociación de variables. La media de edad fue 34,7 ± 6,6 años y del período posparto, 3,5 ± 2,6 años. En 8,7 por ciento se hizo el diagnóstico de diabetes, 32,6 por ciento intolerancia a la glucosa y 12,0 por ciento, glucemia alterada en ayunas. 62,1 por ciento presentaba obesidad abdominal, 62,5 por ciento, algún tipo de dislipidemia y 23,80 por ciento, elevación de la presión arterial. 46,4 por ciento reunía los criterios de SM y 29,6 por ciento mostró un índice HOMA-R > 2,5. Las cifras de CA, IMC, triglicéridos, glucemia basal, glucemia 2 horas post-carga, e insulina 2 horas poscarga fueron más altas (P< 0,05) en mujeres con anormalidades de la tolerancia a la glucosa que en aquellas con tolerancia normal. Las mujeres con DMG previa muestran una elevada frecuencia de alteraciones clínicas y metabólicas que representan un potencial incremento del riesgo cardiovascular en un grupo poblacional relativamente joven
To know the frequency of diabetes and other cardiovascular risk factors in women with previous gestational diabetes mellitus (GDM). 92 women with previous GDM, without diagnosis of diabetes, who underwent initial or annual postpartum diabetes screening during 2008, were assessed. Blood pressure, abdominal circumference and body mass index were measured. They were tested for an oral glucose tolerance test (OGTT) and determination of plasma insulin and lipid levels. Metabolic syndrome (MS) was diagnosed according ATP III criteria and the HOMA-R model was used for the insulin resistance index calculation. Students t test was used for variables association. The average age was 34.7 ± 6.6 years and postpartum period, 3.5 ± 2.6 years. 8.7 percent was diagnosed with diabetes, 32.6 percent with impaired glucose tolerance and 12.0 percent with impaired fasting glucose. 62.1 percent showed abdominal obesity, 62.5 percent presented some type of dyslipidemia and 23.8 percent, high blood pressure. 46.4 percent met the criteria for MS, and 29.6 percent showed a HOMA-R Index > 2.5. Abdominal circumference, body mass index, blood pressure, triglycerides, basal glucose, 2-h post-load glucose and 2-h post-load insulin values were higher (P< 0.05) in women with abnormal glucose tolerance than those with normal glucose tolerance. Women with previous GDM show a high frequency of clinical and metabolic abnormalities that point towards a potential increase of cardiovascular risk in a relatively young population
