Rates of overweight and obesity were compared with matched population survey results. Results: Data from 308 youth and 283 young adults were included. In girls, significantly higher prevalence of overweight and obesity were seen in the 5–8 (43% vs. 18%), 13–16 (41% vs. 27%), 18–24 (46% vs. 34%) and 25–30 (60% vs. 43%) years age groups; whereas in boys increased prevalence was observed in the 5–8 years age group only (41% vs. 18%). Rates of overweight and obesity increased with age across sexes. In youth, BMI standard deviation score was correlated with socio‐economic status, insulin regimen, blood pressure and blood lipids (P < 0.05). In adults, BMI was positively associated with blood pressure, and longer diabetes duration (P < 0.02). Conclusions: Overweight and obesity are over‐represented in young persons with type 1 diabetes, particularly girls. As overweight is associated with other cardiovascular disease markers early intervention is paramount.]]> Wed 06 Apr 2022 13:57:00 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30870 P = 0.02; odds ratio (OR) 0.992, P = 0.03] and more time with BGL in the 7–10 mmol/l range (31 ± 34% vs. 18 ± 27%, P = 0.003; OR 1.013, P = 0.003) compared with those without neonatal hypoglycaemia. Although statistically significant, receiver operating characteristic (ROC) curve analysis showed that time spent with maternal BGLs in the range 4–7 mmol/l [area under the curve (AUC) = 0.58] or 7–10 mmol (AUC = 0.60) was not strong enough to be a useful clinical predictor of neonatal hypoglycaemia. HbA_1c in the second trimester of pregnancy (P = 0.02, OR 1.42) and percentage time spent in BGL range of 7–10 mmol/l (P = 0.001, OR 1.02) were both associated with a risk of neonatal hypoglycaemia in a logistic regression model. HbA_1c in the third trimester (P = 0.07, OR 1.28) approached, but did not reach, significance. Conclusions: These data support a BGL range of 4–7 mmol/l as an intrapartum target. Glycaemic control in the second trimester is associated with neonatal hypoglycaemia. Improvement in ante- and intrapartum glycaemic control may reduce neonatal hypoglycaemia in women with pre-existing diabetes.]]> Thu 17 Mar 2022 14:40:12 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:34937 10 mmol/l), occurrence of maternal hypoglycaemia (BGL < 3.8 mmol/l), and incidence of neonatal hypoglycaemia (BGL ≤ 2.5 mmol/l) if betamethasone was administered within 48 h of birth. Results: The cohorts comprised 151 women (Adult‐IVI n = 86; Pregnancy‐IVI n = 65). The primary outcome was 68% time‐at‐target [95% confidence interval (CI) 64–71%) for Pregnancy‐IVI compared with 55% (95% CI 50–60%) for Adult‐IVI (P = 0.0002). Critical maternal hyperglycaemia (0% vs. 2%, P = 0.02) and hypoglycaemia (2% vs. 12%, P = 0.02) were both lower with Pregnancy‐IVI than Adult‐IVI. Neonatal hypoglycaemia was less common after Pregnancy‐IVI (29%) than after Adult‐IVI (54%, P = 0.03). A multiple logistic regression model adjusting for potential confounders gave an odds ratio for neonatal hypoglycaemia with Pregnancy‐IVI of 0.27 (95% CI 0.10–0.76, P = 0.01). Conclusions: An IVI protocol designed for pregnancy effectively controlled maternal hyperglycaemia following betamethasone administration in GDM. This is the first intervention to show a reduction in betamethasone‐associated neonatal hypoglycaemia, linked with optimum maternal glycaemic control.]]> Thu 04 Nov 2021 10:39:22 AEDT ]]>
