Sensitivity of fasting glucose for gestational diabetes mellitus screening in Mexican adolescents based on International Association of Diabetes and Pregnancy Study Groups criteria: a diagnostic accuracy study based on retrospective data analysis.

Objective: To evaluate fasting plasma glucose (FPG) as a screening test for gestational diabetes mellitus (GDM) among Mexican adolescents using International Association of Diabetes and Pregnancy Study Groups criteria.

Design: Retrospective cohort study.

Setting: Level-three medical institution in Mexico City.

The importance of gestational diabetes beyond pregnancy.

Diabetes mellitus is the main health problem affecting Mexico's population. The mechanisms by which susceptibility to it is acquired and diabetes develops are topics of ongoing research. In order to prevent type 2 diabetes, one of the challenges is to fully understand gestational diabetes and the hormonal changes and altered carbohydrate metabolism that are associated with it during fetal development.

[Effect of betamethasone in blood glucose levels in pregnant diabetic women at risk of preterm birth].

Background: The bethametasone (BTM) induced hyperglycemia is not adequately known and managed in diabetic pregnant women.

Objective: To compare the betamethasone-induced hyperglycemia in pregnant women either healthy or with gestational or type 2 diabetes mellitus (diabetes mellitus).

Material And Methods: Forty volunteer pregnant women at risk of premature rupture of membranes who received betamethasone (12 mg i.

[Gestational diabetes mellitus. Experience at a third level hospital].

Background: The prevalence of type 2 diabetes mellitus and of gestational diabetes mellitus is high in the Mexican population; thus, strategies to improve its detection and prevent obstetric and perinatal complications are essential.

Patients And Methods: During the period 2000-2004 a total of 8,074 pregnant women were studied from the day of performance, 50-g, 1 hour glucose screening test for gestational diabetes mellitus (ST-GDM) until the end of pregnancy using the same protocol: ST-GDM was performed immediately after 14 weeks of gestation in high-risk women and between 24-28 weeks in those with regular risk. Two weeks later 100-g, 3 hour oral glucose tolerance test (3h-OGTT) was performed in women with ST-GDM [symbol: see text] 130 but < 180 mg/dL, and patients were classified according to Freinkel's criteria in class A1, A2 and B1 gestational diabetes mellitus.

Gestational diabetes mellitus and glucose intolerance among Mexican pregnant adolescents.

There is an increasing incidence of type 2 diabetes mellitus (DM) among adolescents (especially females), and the serum glucose concentrations in pregnant women <25 years during a 3-h oral glucose tolerance test (3-h OGTT) seem to be lower than those of pregnant women >25 years. Among 115 Mexican pregnant adolescents (<18 years) we analyzed their serum glucose concentrations during: a) 1-h 50-g glucose challenge test (GCT) performed at 24-28 weeks of gestation (n = 103) or at 29-35 weeks of gestation (n = 12); b) A standard 3-h OGTT performed 3-5 days later. Eight adolescents had an abnormal GCT, three of whom also had an abnormal 3-h OGTT.
