AIMS:The aim of the study was to evaluate the effect of a Mediterranean diet (MedDiet), enhanced with extra virgin olive oil (EVOO) and nuts, on a composite of adverse maternofoetal outcomes of women with normoglycemia during pregnancy.

METHODS:This was a sub-analysis of the St Carlos gestational diabetes mellitus Prevention Study. Only normoglycemic women were analysed (697). They were randomized (at 8-12th gestational weeks) to: standard-care control group (337), where fat consumption was limited to 30% of total caloric intake; or intervention group (360), where a MedDiet, enhanced with EVOO and pistachios (40-42% fats of total caloric intake) was recommended. The primary outcome was a composite of maternofoetal outcomes (CMFOs): at least having 1 event of emergency C-section, perineal trauma, pregnancy-induced hypertension and preeclampsia, prematurity, large-for-gestational-age and small-for gestational-age.

RESULTS:Crude relative risk showed that the intervention was associated with a significant reduction in the risk of CMFOs (0.48 [0.37-0.63]; p = 0.0001), with a number-needed-to-treat = 5. Risk of urinary tract infections, emergency C-sections, perineal trauma, large-for-gestational-age and small-for gestational age new-borns were also significantly reduced.

CONCLUSION:A MedDiet, enhanced with EVOO and nuts, was associated with a risk reduction of CMFOs in over 50% in normoglycemic pregnant women. Therefore, it might be a potentially adequate diet for pregnant women.

Background and aim Gestational diabetes mellitus (GDM) poses a threat to the mother and child. The aim of this study was to examine the effect of acupressure on the glycemic control and insulin requirement of GDM females. Materials and methods Thirty GDM female patients were randomized to either the study group (SG; n=15), which was treated with acupressure and the standard antenatal care, or the control group (CG; n=15), which was treated with the standard antenatal care. Fasting and 2-h post-prandial blood glucose levels, requirement for insulin and insulin resistance were measured at 24 and 36 weeks' gestation (WG). Also, neonatal outcomes were registered at delivery. Results The pre intervention showed no statistically significant differences between SG and CG for baseline characteristics of participants (p>0.05). Within group analyses, after 12 weeks intervention had shown that 75 g oral glucose tolerance test (OGTT), insulin resistance, number of required insulin and measure of utilized insulin were significantly reduced (p<0.05), with significant increase in body mass index (BMI) (p<0.05) in both groups. All outcome measures were not significantly changed (p>0.05) between both groups at 24 and 36 WG. No significant differences (p>0.05) in pregnancy and neonatal outcomes between both groups at labor. Conclusions Acupressure may help to reduce gestational diabetes or insulin treatment for overweight female patients with GDM.

Objectives:Prenatal and early life factors such as Gestational Diabetes Mellitus (GDM), exclusive breastfeeding (EBF), and early exposure to sugar-sweetened beverages (SSBs) may contribute to obesity in children. The relationship of EBF and SSBs with obesity prevalence in children exposed to GDM has rarely been evaluated. This study examined the association of EBF and early SSBs consumption with obesity prevalence in children (1-5y) born to mothers with and without GDM.

Methods:This study used data from the 2014 Los Angeles County Women, Infants, and Children(WIC) Survey, which included 3,707 mothers and their children (1-5y). Infants (1-2y) with weight-for-height ≥ 97.7percentile were classified as subjects with high weight-for-length and children (2-5y) were classified as subjects with obesity if their BMI-for-age was ≥ 95percentile.

Results:The individual and combination interaction effects of GDM, SSBs intake, and EBF on obesity prevalence were all significant ( < 0.05). Compared to GDM offspring, with low SSBs intake, and who were EBF (referent), those who were GDM, with high SSBs intake and who were EBF had approximately a five-fold increase in odds of obesity (OR = 4.77, 95%CI 1.55-8.60, = 0.03). Compared to the GDM referent group, GDM offspring who were not EBF with low and high SSBs intake had 4.3- and 4.4-times higher odds of obesity, respectively (OR = 4.33, 95%CI 1.42- 8.07, = 0.01; OR = 4.38, 95%CI 1.39- 8.16, = 0.01). Using non-GDM, EBF and low SSBs as referent, those who were not EBF, with either high or low SSBs had approximately a 4-fold increase in odds of obesity (OR = 3.62, 95%CI: 2.16-6.05, < 0.0001; OR = 3.83, 95%CI: 2.26-6.48, < 0.0001).Compared to the non-GDM referent group, those who were EBF and had high SSBs intake had 77% higher odds of obesity (OR = 1.77, 95%CI 0.93-3.37, = 0.001).

Conclusions:In non-GDM offspring, EBF was protective against odds of obesity in both high and low SSBs consumers. In GDM offspring, EBF was only protective against obesity when SSBs intake was low. Surprisingly, GDM offspring who were EBF and had high SSBs consumption had a 4- to 5-fold increase in odds of obesity compared to those not EBF with either low or high SSBs intake. These results suggest that interventions should focus on the combined protective effects of EBF and low SSBs intake, particularly in GDM offspring.

OBJECTIVE: To examine whether low maternal dietary intake of vitamin C and low maternal plasma ascorbic acid (AA) concentrations are associated with an increased risk of gestational diabetes mellitus (GDM). METHODS: Cases were 67 women with GDM meeting National Diabetes Data Group criteria. Controls were 260 women without such a diagnosis. Maternal dietary vitamin C consumption during the periconceptional period and during pregnancy was assessed using a 121-item, semiquantitative food frequency questionnaire. Maternal plasma AA concentrations were determined using automated enzymatic procedures on specimens collected during the intrapartum period. RESULTS: Mean maternal daily consumption of vitamin C and plasma AA concentrations were 10% and 31% lower, respectively, among GDM cases as compared with controls (130.7 +/- 10.2 vs. 145 +/- 4.9 mg/d, P = .190; 36 +/- 2.0 vs. 53 +/- 1.0 micromol/L, P<.001). After controlling for maternal age, race, prepregnancy adiposity, family history of type 2 diabetes, energy intake and income, women reporting low daily vitamin C intake (<70 mg/d), as compared with the other women, experienced a 3.7-fold increased risk of GDM (odds ratio [OR] = 3.7, 95% confidence interval [CI] 1.7-8.2). There was a linear relation in risk of GDM with decreasing concentrations of plasma AA (P for linear trend<.001). After adjusting for confounders, women in the lowest quartile (<42.6 micromol/L), as compared with women in the highest quartile (>63.3 micromol/L), experienced>12-fold increased risk of GDM (OR = 12.8, 95% CI 3.5-46.2). CONCLUSION: Low maternal dietary vitamin C intake and low plasma AA concentrations are associated with an increased risk of GDM. Large, prospective, cohort studies are needed to further evaluate the potential beneficial role of vitamin C and other antioxidants in the prevention of impaired glucose tolerance in pregnancy.
