BackgroundGestational diabetes mellitus (GDM) is defined as a glucose tolerance disorder that arises during pregnancy. Estimates of its prevalence vary widely because of varying threshold values. Screening of all pregnant women with a two-step test has been available in Germany since 2012. This study is the first population-based, nationwide analysis of the screening coverage and the resulting one-year prevalence.MethodsBilling data from the outpatient sector were analyzed for all persons covered by statutory health insurance in the two-year period 2014-2015. A cohort of pregnant women, constructed by using pregnancy care billing data, was studied with respect to the screening coverage. The prevalence of GDM was determined from the use of the corresponding ICD-10-GM codes.Results80.8% of 567 191 pregnant women were screened for GDM. Most of them (63.3%) received only the pre-test, and 12.7% received both the pre-test and the diagnostic test. 4.8% received only the diagnostic test. The overall prevalence of GDM was 13.2%. The prevalence rose with age, from 8% to 26% in women aged 45 or older. Younger women more commonly received only the pre-test; the frequency of receiving both tests rose with age.ConclusionScreening for GDM is comprehensively implemented. The analysis of billing data reveals a relatively high prevalence that accords with estimates in other countries, implying that earlier prevalence figures for Germany were probably underestimates.
