Impact of using the international association of diabetes and pregnancy study groups criteria in South Auckland: prevalence, interventions and outcomes

Abstract

Adopting the modified IADPSG criteria will result in a 62% increase in the number of GDM cases with a significant impact on workload and resources. Currently, there is insufficient evidence to support the introduction of the IADPSG criteria for our service.

Impact of the new IADPSG gestational diabetes diagnostic criteria on pregnancy outcomes in Western Australia

“…To our knowledge, this is the first study to compare the perinatal outcomes of women with GDM diagnosed by the 1998 ADIPS and proposed IADPSG criteria. Other studies comparing the IADPSG criteria with various other diagnostic criteria have shown increases in the incidence of GDM, but the influence upon perinatal outcomes has been variable . This variability likely represents the impact of differing demographic characteristics of the populations assessed and the differing diagnostic criteria compared.…”

The IADPSG diagnostic criteria identify women with increased risk of adverse pregnancy outcomes in Victoria

“…Studies have reported varied perinatal outcomes in untreated women meeting IADPSG criteria compared to women without GDM. A United States cohort with a large African‐American contingent found increased fetal overgrowth, a Canadian study found no difference, a New Zealand study (55% Maori or Pacific Islander) found increased birthweight and induction, and a Western Australia study (predominantly Caucasian women) reported increased birthweight and macrosomia . Compared to the aforementioned studies, in our larger multicultural cohort with adjustment for confounders including BMI and region of birth, we found that IADPSG‐only criteria identified women and babies with increased risk of gestational hypertension, caesarean section, LGA and shoulder dystocia.…”

“…These criteria (fasting plasma glucose (FPG) ≥5.1 mmol/L, and/or one hour glucose ≥10 mmol/L and/or two hour glucose ≥8.5 mmol/L) have caused substantial debate and are variably endorsed by international societies due to concerns regarding increases in diagnosis and health service demands without clear evidence for improved outcomes . There are multiple studies internationally examining the impact of IADPSG criteria on perinatal outcomes with inconsistent findings …”

Effect of new diagnostic criteria on detection and pregnancy outcomes of gestational diabetes mellitus: a retrospective study

“…The effects of changes in cut-off values of FBG and 2HG on the detection rate of GDM and pregnancy outcomes have been reported 7,8 . However, studies of the additional 1HG test on the pregnancy outcomes are limited.…”
