Relation of the Mediterranean diet with the incidence of gestational diabetes

Background/objectives: Some studies document relationships of the incidence of gestational diabetes mellitus (GDM) with individual components of the diet, but studies exploring relationships with patterns of eating are lacking. This observational study aimed to explore a possible relationship between the incidence of GDM and the Mediterranean diet (MedDiet) pattern of eating. Subjects/methods: In 10 Mediterranean countries, 1076 consecutive pregnant women underwent a 75-g OGTT at the 24th-32nd week of gestation, interpreted both by the ADA-2010 and the International Association of the Diabetes and Pregnancy Study Groups (IADPSG)-2012 criteria. The dietary habits were assessed by a previously validated questionnaire and a Mediterranean Diet Index (MDI) was computed, reflecting the degree of adherence to the MedDiet pattern of eating: a higher MDI denoting better adherence. Results: After adjustment for age, BMI, diabetes in the family, weight gain and energy intake, subjects with GDM, by either criterion, had lower MDI (ADA-2010, 5. 8 vs 6. 3, P=0. 028; IADPSG-2012, 5. 9 vs 6. 4, P<0. 001). Moreover, the incidence of GDM was lower in subjects with better adherence to the MedDiet (higher tertile of MDI distribution), 8. 0% vs 12. 3%, OR=0. 618, P=0. 030 by ADA-2010 and 24. 3% vs 32. 8%, OR=0. 655, P=0. 004 by IADPSG-2012 criteria. In subjects without GDM, MDI was negatively correlated with both fasting plasma glucose and AUC glucose, P<0. 001 for both. Conclusions: Adherence to a MedDiet pattern of eating is associated with lower incidence of GDM and better degree of glucose tolerance, even in women without GDM. The possibility to use MedDiet for the prevention of GDM deserves further testing with intervention studies.peer-reviewe

Epidemiology of type 2 diabetes mellitus in Aleppo, Syria

Background: Type 2 diabetes mellitus (T2DM) is considerable public health problem, but data on the prevalence and correlates of T2DM in Syria are scarce. The aim of the present study was to establish reliable estimates of the prevalence of T2DM in Syria. Methods: A cross-sectional, population-based survey was conducted in Aleppo, Syria (population 2.5 million), in 2006. The study was conducted on a random sample of 1168 subjects ≥25 years of age (47.7% men; mean age 44.7 ± 12.7 years). Information regarding a personal history of diabetes and other risk factors was collected, followed by measurement of weight, height, and the waist:hip ratio (WHR). Of the 1168 participants, 806 provided fasting blood samples that were analyzed for fasting plasma glucose (FPG) and HbA1c. Results: The prevalence of T2DM based on FPG ≥126 mg/dL and HbA1c ≥6.5% was 15.6% (11.2% self-reported; 5.0% diagnosed) and 14.8%, respectively. The prevalence of impaired fasting glucose (FPG ≥110 and \u3c126 mg/dL) was 8.6%. There was a significant positive association between T2DM and age, WHR, a family history of T2DM, and body mass index (BMI) and an inverse association between T2DM and physical activity (P \u3c 0.01 for all). Multivariate analysis showed that age, BMI, WHR, and a family history of T2DM were the most important factors associated with T2DM. Only 16.7% of treated cases of T2DM were under control (i.e. HbA1c \u3c7%). Conclusions: Based on the results obtained in our sample, T2DM is widespread in Syria. Many of those with T2DM are unaware of their disease and most have unsatisfactory control of their disease. © 2009 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and Blackwell Publishing Asia Pty Ltd
