The purpose of this study was to investigate the effects of maternal gestational diabetes mellitus (GDM) and breast feeding on childhood overweight and obesity in a mainland Chinese population. The incidence of and factors associated with overweight and obesity were compared between children of mothers with (n=1068) and without (n=1756) GDM. The independent roles of the associated factors were examined by multiple logistic regression analysis. The incidence of overweight was higher (16.6 v. 12.6%, P=0.002) in the GDM group, but that of obesity was not different (10.7 v. 12.0%, P=0.315). At age 1-2 and 2-5 years, no difference in overweight (11.0 v. 12.0%, P=0.917, and 15.7 v. 14.6%, P=0.693, respectively) was found, while obesity (8.0 v. 13.6%, P=0.019, and 8.4 v. 13.4%, P=0.014, respectively) was less frequent in the GDM offspring. At age 5-10 years, increased overweight (22.2 v. 12.1%, P<0.001) and obesity (15.9 v. 9.0%, P=0.001) were found in the GDM group, which was associated with maternal obesity, being born large-for-gestational age, male gender and formula feeding. After adjusting for confounding factors, GDM remained an independent determinant of offspring overweight and obesity (aOR 2.28, 95% CI 1.61-3.22), suggesting that the effects of GDM were independent of breast feeding, as well as of maternal obesity and birth size.
Background: There is considerable variation in recommendations from clinical practice guidelines on when and how to screen for glucose intolerance in people with cystic fibrosis (CF). In terms of glucose tolerance, the Australian Standards of Care state that blood glucose monitoring should be performed to exclude hyperglycaemia on a regular basis. Annual oral glucose tolerance test (OGTT) in patients 10 years or older should be considered and performed in patients with symptoms suggestive of glucose impairment or unexplained weight loss, growth failure or worsening respiratory disease. In 2018, 13 (14%) of the eligible 99 patients with CF ≥10 years old had an OGTT. Aims: To evaluate the added benefit of enhanced screening to children and adolescents with CF by improving screening to 50% by the end of 2020. Methods: A prospective cross-sectional quality improvement cycles was performed on patients in the CF clinic, ≥11 years for OGTT. Patients were excluded from OGTTs if they were prescribed insulin or prolonged oral/parenteral steroids. Multiple quality improvement initiatives were tried. Each intervention was done as a plan-do-study-act cycles with refinement between each. Results: Screening for CF related diabetes (CFRD) increased in 2020 to 60% of >10 year olds. Four patients had new results suggestive of CFRD and ten had new impaired glucose tolerance. The most successful strategy was sending letters to families. Conclusion: The Australian Standards of Care may require revision, as there may be a benefit of routine screening of all children at certain ages as opposed to waiting for symptoms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
