ABSTRACT To investigate the trend in the prevalence of gestational diabetes mellitus during 1999-2008 in women living in urban Tianjin, China.
A universal screening for gestational diabetes mellitus has become an integral part of the antenatal care in Tianjin, China from 1998. A total of 105,473 pregnant women living in the six urban districts of Tianjin, China, participated in the gestational diabetes mellitus screening programme between December 1998 and December 2008. The screening test consisted of a 50-g 1-h glucose test. Women who had a glucose reading ≥7.8 mmol/l at the initial screening were invited to undergo the standard 2-h oral glucose tolerance test with a 75-g glucose load. Gestational diabetes mellitus was confirmed using the World Health Organization's diagnostic criteria.
The adjusted prevalence of gestational diabetes mellitus increased by 2.8 times during 1999-2008, from 2.4 to 6.8% (P<0.0001 for linear trend). In 2008, the age-specific prevalence of gestational diabetes mellitus was the highest among women aged 30-34 years (11.3%) and lowest among women aged 25 and under (1.2%). In women aged 35 years and more, the prevalence was 5.3%.
The prevalence of gestational diabetes mellitus has markedly been increasing in a universally screened urban Chinese female population and has become an important public health problem in China.

    ABSTRACT: Abstract This review aims to evaluate the effectiveness of low glycemic index (GI) dietary intervention for the treatment of gestational diabetes mellitus (GDM), specifically from the Asian perspective. A systematic review of the literature using multiple databases without time restriction was conducted. Three studies were retrieved based upon a priori inclusion criteria. While there was a trend towards improvement, no significant differences were observed in overall glycemic control and pregnancy outcomes in GDM women. However, a tendency for lower birth weight and birth centile if the intervention began earlier was noted. Low GI diets were well accepted and had identical macro-micronutrient compositions as the control diets. However, due to genetic, environment and especially food pattern discrepancies between Western countries and Asians, these results may not be contributed to Asian context. Clearly, there are limited studies focusing on the effect of low GI dietary intervention in women with GDM, particularly in Asia.

    ABSTRACT: Objective: To evaluate the effects of pre-pregnancy body mass index (BMI) and weight change from pre-pregnancy to postpartum on postpartum type 2 diabetes (T2D) risk among women with gestational diabetes (GDM). Design and Methods: We performed a retrospective cohort study in 1263 GDM women at 1-5 years after delivery. Cox proportional hazards regression models were used to evaluate the association of pre-pregnancy BMI and weight change with T2D and pre-diabetes risks. Results: The multivariable-adjusted hazard rations based on different levels of pre-pregnancy BMI (<23, 23-24.9, 25-29.9, and ≥30 kg/m(2) ) were 1.00, 1.77, 2.35, and 6.54 (Ptrend <0.001) for incident T2D, and 1.00, 1.46, 1.87, and 1.79 (Ptrend <0.001) for incident pre-diabetes, respectively. Compared with women with stable weight (±3 kg), those with weight gain ≥7 kg had an 86% and a 32% increased risk of diabetes and pre-diabetes, and those with weight loss ≥3 kg had a 45% decreased risk of pre-diabetes. The positive associations of pre-pregnancy BMI with incident diabetes and pre-diabetes risk were persistent in women with different levels of weight change (<3 kg and ≥3 kg). Conclusion: Pre-pregnancy obesity and excessive weight gain from pre-pregnancy to postpartum increase postpartum diabetes and pre-diabetes risks among GDM women.

    ABSTRACT: There has been a marked increase in the prevalence of diabetes in Asia over recent years. Diabetes complicating pregnancy, in particular gestational diabetes, has also increased markedly in the region. Multi-ethnic studies have highlighted the increased risk of gestational diabetes mellitus among the different Asian populations. Prevalence of gestational diabetes in Asian countries varies substantially according to the screening strategy and diagnostic criteria applied, and ranges from 1% to 20%, with evidence of an increasing trend over recent years. The International Association for Diabetes in Pregnancy Study group criteria have been adopted by some Asian countries, although they present significant challenges in implementation, especially in low-resource settings. Studies on offspring of mothers with gestational diabetes have reported adverse cardiometabolic profiles and increased risk of diabetes and obesity. Gestational diabetes is likely to be a significant factor contributing to the epidemic of diabetes and other non-communicable diseases in the Asian region. In recognition of this, several large-scale prevention and intervention programmes are currently being implemented in different Asian countries in order to improve glucose control during pregnancy, as well as overall maternal health. Lessons emerging from gestational diabetes studies in Asia may help inform and provide insights on the overall burden and treatment strategies to target gestational diabetes, with the ultimate aim to reduce its adverse short- and long-term consequences.
