RESUMO
BACKGROUND: Maternal metabolic derangements associated with early pregnancy gestational diabetes may affect the fetus differently compared with gestational diabetes diagnosed later in pregnancy. The aim of this observational study was to assess neonatal outcomes according to timing of gestational diabetes diagnosis in obese women. METHODS: Women ≥18 years of age with a pre-pregnancy body mass index ≥30 kg/m2 were grouped according to the results of a 75 g 2-h oral glucose tolerance test performed at 13.1 weeks of gestation and repeated at 23.4 weeks if normal at first testing. The main outcomes were birthweight and large for gestational age. RESULTS: Out of 361 women, 164 (45.4%) were diagnosed with gestational diabetes, 133 (81.1%) of them in early pregnancy. The mean offspring birthweight was 3673 g (standard deviation (SD) 589 g) in the early and 3710 g (SD 552 g) in the late gestational diabetes group. In a multivariate logit model, the odds ratio for large for gestational age was 2.01 (95% CI: 0.39-10.39) in early compared with late gestational diabetes. CONCLUSIONS: We observed no statistically significant differences in neonatal outcomes according to timing of gestational diabetes diagnosis. In addition to lack of power, early treatment of hyperglycemia may partly explain the results.

BACKGROUND: Healthy diets before and during pregnancy have been suggested to reduce the risk of gestational diabetes (GDM). Several lifestyle intervention studies for pregnant women have reported dietary improvements after counselling. However, evidence concerning the effect of counselling initiated before pregnancy on diets is limited. METHODS: This randomised controlled study explored whether pre-pregnancy lifestyle counselling influenced food intakes, as well as whether changes in food intakes were associated with GDM. The participants comprised 75 women with prior GDM and/or a body mass index ≥ 30 kg m-2 . Women were randomised into a control or an intervention group, and their food intakes were followed from pre-pregnancy to early pregnancy using a food frequency questionnaire. The control and intervention groups were combined to assess the association between changes in food intakes and GDM. The diagnosis of GDM was based on a 75-g oral glucose tolerance test conducted in the first and second trimester of pregnancy. RESULTS: Pre-pregnancy lifestyle counselling showed no major overall effect on food intakes. The intake of low-fat cheese increased significantly in women who did not develop GDM compared to women who did after adjusting for potential confounders (P = 0.028). This association was not observed for regular-fat cheese. CONCLUSIONS: The findings obtained in the present study suggest that an increased intake of low-fat but not regular-fat cheese between pre-pregnancy and early pregnancy is associated with a lower risk of GDM in high-risk women.

AIM: To assess in women at high risk of gestational diabetes mellitus (GDM) the effect of a lifestyle intervention on the metabolic health of their offspring around 5 years after delivery. METHODS: For the original Finnish gestational diabetes prevention study (RADIEL), 720 women with a prepregnancy body mass index (BMI)≥30kg/m2 and/or previous GDM were enrolled before or during early pregnancy and allocated to either an interventional (n=126) or conventional (n=133) care group. The present 5-year follow-up substudy assessed the metabolic health outcomes of their offspring. Age- and gender-standardized residuals of metabolic health components (waist circumference, mean arterial pressure, high-density lipoprotein and triglyceride levels, and fasting insulin/glucose ratio) were also combined to determine the accumulation of metabolic effects. Body composition was assessed by electrical bioimpedance. RESULTS: Offspring of women in the intervention group had a less optimal metabolic profile after the 5-year follow-up compared with offspring in the usual care group (P=0.014). This difference in metabolic health was primarily related to lipid metabolism, and was more prominent among boys (P=0.001) than girls (P=0.74). Neither GDM, gestational weight gain, prepregnancy BMI, offspring age nor timing of randomization (before or during pregnancy) could explain the detected difference, which was also more pronounced among the offspring of GDM pregnancies (P=0.010). Offspring body composition was similar in both groups (P>0.05). CONCLUSION: The lifestyle intervention aimed at GDM prevention was associated with unfavourable metabolic outcomes among offspring at around 5 years of age.

RESUMO
The aim of this study was to find the association between adherence to the Nordic Nutrition Recommendations (NNR) and glucose metabolism. Participants were 137 pregnant obese women or women with a history of gestational diabetes (GDM) from the Finnish Gestational Diabetes Prevention Study. Adherence to the NNR was assessed by the Healthy Food Intake Index (HFII) calculated from the first trimesters' food frequency questionnaires. Higher HFII scores reflected higher adherence to the NNR (score range 0-17). Regression models with linear contrasts served for the main analysis. The mean HFII score was 10.0 (s.d. 2.8). The odds for GDM decreased toward the higher HFII categories (P=0.067). Fasting glucose (FG) and 2hG concentrations showed inverse linearity across the HFII categories (P(FG)=0.030 and P(2hG)=0.028, adjusted for body mass index, age and GDM/pregnancy history). Low adherence to the NNR is associated with higher antenatal FG and 2hG concentrations and possibly GDM.

BACKGROUND/OBJECTIVES: The prevalence of gestational diabetes mellitus (GDM) is increasing worldwide. GDM may be prevented by improving the diets of pregnant women. The objective of this study was to evaluate the effect of dietary counselling on the diets of pregnant women at GDM risk. SUBJECTS/METHODS: This study was a secondary analysis of a randomised controlled trial the Finnish gestational diabetes prevention study (RADIEL) in which pre-pregnant and pregnant women with previous GDM or BMI ⩾30 kg/m(2) were allocated into two groups, namely the control and the intervention groups. The control group received standard antenatal dietary counselling according to the Finnish Nutrition Recommendations. The intervention group participated in one individual dietary counselling session and one group dietary counselling session in addition to the standard counselling. This study included women who were recruited during pregnancy. To assess changes in food intake, food-intake questionnaires were collected during the first and the second trimester of pregnancy. Bootstrap type analysis of covariance was used, and 242 participants were included in the final analysis to study changes in food intake. RESULTS: The intakes of low-fat cheese (baseline adjusted mean 0.09 times/day; 95% confidence interval (CI) 0.07, 0.24; P=0.040) and fish (baseline adjusted mean 0.28 times per week; 95% CI 0.08, 0.49; P=0.011) showed a significant increase in the intervention group compared with the control group. CONCLUSIONS: This study showed that dietary counselling in early pregnancy can lead to modest dietary improvements in pregnant women at GDM risk.

OBJECTIVE: The purpose of this study is psychometric assessment of disease-specific questionnaire, Urinary Incontinence Severity Score (UISS) and Visual Analogue Scale (VAS) in urinary incontinent women. We also investigated functional relationship between UISS, VAS and 15D-valid, generic health-related quality-of-life (HRQoL) instrument. MATERIALS AND METHODS: Eighty-two incontinent female patients were recruited for the study that included baseline investigation and re-evaluation 13 months (range 6-21 months) after treatment. Twenty-nine control women who had urinary incontinence but were not bothered by it completed the HRQoL measurements. RESULTS: Internal consistency and content validity of UISS was good. Both measures UISS and VAS were reproducible, Spearman's rank correlation between test-retest were 0.88 and 0.85 respectively. The control women's UISS, 15D and VAS scores were significantly lower than the patient's scores (p<0.001, Mann-Whitney U test) which proves to be a good discriminant. The changes in pad test correlated moderately well with those in the VAS and UISS. The UISS, VAS and 15D in the improved group had responsiveness (Guyatt's) statistics: 1.48, 1.74 and -0.80 respectively. CONCLUSION: The UISS and VAS proved to be valid, reproducible and responsive to treatment for UI women. The functionality of the 15D was good but it demonstrated less sensitivity to changes after treatment.
