[Suitability of screening for diabetes mellitus in women with a history of gestational diabetes].
OBJECTIVE
To assess long-term suitability of screening for type 2 diabetes mellitus in women with a previous diagnosis of gestational diabetes in Primary Care. The secondary objectives were to determine if there were clinical factors that modified the usefulness of the screening.


METHODS
An observational cohort type study was performed, which included all patients with the diagnosis of gestational diabetes during the years 2000 to 2009 (n=470) in the University Hospital Complex of Ourense. The electronic medical records were reviewed to assess the existence of gestational diabetes and the year of the last fasting blood glucose. The mean follow-up time was 12.9 years. The screening for evidence of a fasting blood glucose in the last 3 years was considered adequate. The following variables were analysed: adequacy of screening for type 2 diabetes mellitus, age, body mass index, gestational diabetes in more than one gestation, and rural/urban environment. A descriptive analysis of the data was performed, using Chi2 and Student's t-test to determine differences between subgroups. Statistical significance was considered as P<.05 RESULTS: The long-term monitoring of these patients was very irregular. Only 67.08% of the study group underwent diabetes mellitus type 2 screening. The level of follow-up was not associated with age, BMI, the place of residence, or the year of diagnosis. In patients with more than one episode of gestational diabetes, subsequent blood glucose control was achieved in 94.1%.


CONCLUSIONS
The adequacy of the screening in our area is very irregular and highly improvable.
