[Evaluation of the diagnostic criteria of gestational diabetes mellitus in Japan: a study of women with mild glucose intolerance during late pregnancy].
To evaluate the validity of the diagnostic criteria of gestational diabetes (GDM) recommended by the Japan Society of Obstetrics and Gynecology (JSOG), we investigated women with mild glucose intolerance during pregnancy, using the borderline criteria of the Japan Diabetes Society (JDS), cut-off values of which are lower than those of the JSOG criteria. Five hundred seventy one pregnant women were screened for GDM after 20 weeks' gestation using a 50g glucose challenge test. Only ten women (1.8% of total), who fulfilled the JSOG criteria, were found (GDM group). At the same time, eighteen women (3.2% of total), who did not fulfill the JSOG criteria but who met two or more abnormal values of the JDS borderline criteria, were also found (A2 group). There was no significant difference between the two groups in either mean maternal age or the percentage of women over 30 years of age. delta IRI/delta BS in a 75g glucose tolerance test in the A2 group was 0.58 (median), which was similar to that in the GDM group (0.42). This result, however, was significantly lower than that in both the normal control group (1.00, p less than 0.01) and the group of women with only one abnormal value among the JDS criteria (A1 group, 0.88, less than 0.01). Before therapy, there was no significant difference in the diurnal plasma glucose level between the GDM group, who could be treated with diet therapy, and the A2 group.(ABSTRACT TRUNCATED AT 250 WORDS)
