Abstract
Objective
To assess the prevalence of hyperglycemiaaccording to maternal age
and pre-pregnancy body mass index (BMI) among Japanese
women before introduction of the current diagnostic criteria.
Methods
In a retrospective study, data were analyzed from women with
singleton pregnancies who were registered with the JSOG
Successive Pregnancy Birth Registry System and who gave
birth at 22 weeks of gestation or more between January 2007 and December
2009.
Results
Among 138 530 women, 3667 (2.6%) were diagnosed with hyperglycemia including gestational diabetes and diabetes
mellitus. The prevalence of hyperglycemia increased with advancing maternal age and
increasing BMI. Among women aged ≤ 24, 25–34, 35–39, and ≥ 40 years, the prevalence was 0.4%, 0.8%, 1.5%, and 4.0%, respectively, in
lean women (BMI < 18.5); 1.0%, 1.6%, 2.3%, and 3.1%, respectively, in normal
weight women (BMI 18.5–24.9); and 5.7%, 9.2%, 12.9%, and 15.2%, respectively, in
obese women (BMI ≥ 25.0). Of the 1181 newborns with a birth weight of 4000 g or
more, 1046 (88.6%) were born to women not diagnosed with hyperglycemia.
Conclusion
The results may reflect the baseline prevalence of hyperglycemia and
macrosomic neonates (birth weight ≥ 4000 g) during the era of the old diagnostic
criteria in Japan.
