Objective: To analyze the pregestational body mass index and weight gain during pregnancy, and to associate data to perinatal outcomes of pregnant women from a Prenatal Care Program., Methods: A retrospective study was carried out with 151 patients seen at the Healthy Gestation Program of Hospital Israelita Albert Einstein . Data were collected from a medical chart review of the patients seen between March 2015 and March 2016., Results: The chance of developing gestational diabetes for obese patients in early gestation was estimated at 7.5-fold as compared to patients with low or normal body mass index., Conclusion: There was a significant association between obesity in early pregnancy and the occurrence of gestational diabetes mellitus in this population.

Objective: To investigate the relationship between the dietary patterns of pregnant women with maternal excessive body weight and gestational diabetes mellitus., Methods: A cross-sectional study conducted with a convenience sample of 785 adult pregnant women attended by the Unified Health System of Ribeirão Preto, state of São Paulo, between 2011 and 2012. Two 24-hour dietary recalls, corrected by the multiple source method, were employed . For the classification of the body mass index and the diagnosis of gestational diabetes mellitus, the criteria by Atalah and the World Health Organization were used, respectively. Dietary patterns were obtained by principal component analysis using the Varimax rotation method. The relationship between adherence to patterns, overweight and obesity was analyzed by multinomial logistic regression models and the relationship with gestational diabetes mellitus by adjusted unconditional logistic regression models., Results: We identified four dietary patterns: "traditional Brazilian"; "snacks"; "coffee" and "healthy". Women with a higher adherence to the "Healthy" (OR = 0.52; 95%CI 0.33-0.83) and "Brazilian Traditional" patterns (OR = 0.61; 95%CI 0.38-0.96) presented a lower chance of obesity, when compared to women with lower adherence, regardless of confounding factors. After adjustment for maternal excessive body weight, there was no association between dietary patterns and gestational diabetes mellitus., Conclusions: Among the pregnant women, greater adherence to "traditional Brazilian" and "healthy" patterns was inversely associated with obesity, but no relationship was identified with gestational diabetes mellitus after adjusting for excessive body weight. Prospective studies are recommended to investigate the relationship between dietary patterns, overweight and gestational diabetes mellitus, reducing the chance of reverse causality.

Objectives: To evaluate the epidemiological profile and outcomes of women with gestational diabetes mellitus (GDM), determining risk factors for increased vigilance., Subjects and Methods: We studied 924 pregnancies in 916 patients between November 6, 2001 and September 21, 2009., Results: Risk factors were found in 95.1% of cases. The prevalence of maternal diabetes, paternal diabetes and diabetes in other family members was 24.3%, 9.4% and 24.7%, respectively. Predictive factors for insulin use were: screening fasting glucose (FG) ≥ 85, Oral Glucose Tolerance Test (OGTT) FG ≥ 95, 2h glucose after 75 g ≥ 200 mg/dL, previous GDM, obesity, HbA1c > 6%, and the association of risk factors including family history of diabetes mellitus and obesity or previous GDM, the last one the most relevant (p < 0,05)., Conclusions: Risk factors were very sensitive for GDM detection, and provision of family history strengthens its relationship with T2DM. Greater vigilance is recommended for patients with predictive factors for insulin requirement.

Consensus statements by various countries have reported age, obesity, and family history of diabetes mellitus as risk factors for gestational diabetes mellitus. Other factors remain controversial. The aim of this study was to investigate factors associated with gestational diabetes among mothers of newborns from the birth cohort in Pelotas, Rio Grande do Sul State, Brazil, in 2004. We interviewed 4,243 postpartum women in hospital, with a 0.5% refusal rate. Diagnosis of gestational diabetes was self-reported. Prevalence of gestational diabetes was 2.95% (95%CI: 2.53-3.64). Crude analysis using the chi-square test showed a direct association with age, schooling, socioeconomic status, and body mass index (BMI) and an inverse association with maternal height. Non-white color, family history of diabetes mellitus, smoking in the first and second trimesters, and physical activity before the pregnancy and in the first trimester were associated with the outcome. Adjusted hierarchical analysis using logistic regression showed an association with age, non-white color, higher schooling, family history of diabetes, and BMI. Height showed borderline significance. Smoking in the first and second trimesters showed a protective effect.

Objective: To estimate the prevalence of glucose intolerance (diabetes mellitus and impaired glucose tolerance) in women who had their glucose tolerance evaluated and followed up during pregnancy., Methods: Over the last 12 years since the index pregnancy, from a total of 3,113 pregnant women seen in an obstetrics clinic, 551 were randomly selected and proportionally to the number of women in each group. Of these, 529 could be evaluated and had been classified as follows: 250 in group IA (normal glucose tolerance); 120 in group IB (daily hyperglycemia); 72 in group IIA (abnormal oral glucose tolerance test); and 87 in group IIB (abnormal oral glucose tolerance test and daily hyperglycemia). The evaluation consisted of measuring fasting plasma glucose and when the results ranged between 6.1 and 6.9 mmol/L, patients were submitted to oral glucose tolerance test., Results: Prevalence of diabetes mellitus was: IA, 1.6%; IB, 16.7%; IIA, 23.6%; and IIB, 44.8% (IA < [IB = IIA] < IIB; p<0.05). This difference between the groups remained the same for the eight years. Women in IA group were different from others regarding age, parity, and diabetes family history., Conclusion: Hyperglycemia (high plasma glucose levels) and abnormal oral glucose tolerance test during pregnancy are equally effective in predicting the risk for developing maternal diabetes. When both tests are abnormal, this risk is much higher.
