In 1995, Moses et al assessed the prevalence of gestational diabetes mellitus in patients with various risk factors and recommended universal testing. [53] Gestational diabetes mellitus was diagnosed in 6.7% of the women overall, in 8.5% of the women aged 30 years or older, in 12.3% of the women with a preconception body mass index of 30 kg/m2 or greater, and in 11.6% of women with a family history of diabetes in a first-degree relative. A combination of one or all of these risk factors predicted gestational diabetes mellitus in 61% of cases. Gestational diabetes mellitus was present in 4.8% of the women without risk factors. [53]
