Gestational Diabetes and Gestational Impaired Glucose Tolerance in 1653 Teenage Pregnancies: Prevalence, Risk Factors and Pregnancy Outcomes

Maternal body mass index and risk of birth and maternal health outcomes in low‐ and middle‐income countries: a systematic review and meta‐analysis

“…There were 34 prospective cohorts and eight retrospective cohorts. Of the 42 studies, 16 reported preterm birth , 18 low birthweight , seven small for gestational age , five stillbirth , 19 gestational diabetes , nine pregnancy‐induced hypertension , nine pre‐eclampsia , 10 caesarean delivery , three post‐partum haemorrhage and two perinatal mortality . The study‐specific proportion of BMI and events by perinatal and maternal health outcomes are presented in Supporting Information http://onlinelibrary.wiley.com/doi/10.1111/obr.12293/suppinfo.…”

“…Our review data showed that underweight is more prevalent among women pre-pregnancy or during early pregnancy in India (21%) (6), Thailand (18%) (15), Iran (16%) (13) and China (11%) (9). High maternal BMI is common in Turkey (50% of women are overweight and 14% obese) (40) and Brazil (25% of women are overweight and 17% obese) (54). However, some countries, including India (6), China (9), Iran (13) and Thailand (15), are facing problems due to low and high maternal BMI simultaneously.…”

“…There were 34 prospective cohorts and eight retrospective cohorts. Of the 42 studies, 16 reported preterm birth (5,9,10,(13)(14)(15)(16)(38)(39)(40)(41)(42)(43)(44)(45)(46), 18 low birthweight (7,10,11,14,15,39,(41)(42)(43)(44)(45)(47)(48)(49)(50)(51)(52)(53), seven small for gestational age (9,17,39,41,44,54,55), five stillbirth (9,15,16,44,56), 19 gestational diabetes (5,6,9,12,13,…”

Cost-Effectivity Analysis of One-Step Versus Two-Step Screening for Gestational Diabetes

“…Younger age groups have a lower risk for GDM [6]. The prevalence of GDM was found to be 0.85% in a Turkish study of 1,653 young women (≤19 years) [8]. Akbay et al [9] reported a GDM prevalence of 8.9% among Turkish women by measuring plasma glucose levels in a two-step oral glucose tolerance test based on Carpenter-Coustan criteria.…”

The Impact of Polycystic Ovarian Syndrome on Gestational Diabetes

“…Conversely, some studies did not seem to support a higher prevalence and previous history of PCOS in women diagnosed with GDM, when compared to pregnancies in women with normal glucose homeostasis (Wijeyaratne et al, 2006) (Kousta et al, 2000). Obesity, PCOS, and diabetes in first-degree relatives have been described as risk factors for developing GDM and gestational impaired glucose tolerance, especially in young women and teenage pregnancies (<20 years) (Karcaaltincaba et al, 2011). All in all, there is no solid evidence proving the increased risk for GDM in PCOS patients, but a trend assuming that the risk is, indeed, increased in women with PCOS, is recognizable.…”
