title: [Postpartum compliance to oral glucose tolerance test].
abstract: OBJECTIVE
  The main objective of this study is to compare the rate of adherence to GTT done six weeks postpartum (early GTT) to the one performed three months or more after delivery (late GTT). The secondary objective is to determine factors associated to non-adherence to GTT.
  
  
  METHODS
  This is a retrospective study involving women with GDM who delivered in 1998 (late GTT; N=229) and 2003 (early GTT; N=244). We retrieved maternal, pregnancy, newborn and GDM parameters. Statistical analyses include the chi2 test and logistic regression analysis.
  
  
  RESULTS
  The rate of adherence to early GTT (77.1%) was statistically higher than the one observed for late GTT (45.6%; P<0.001). The factors identified as predictors of non-adherence were the year of delivery, parity > or = 2, problem of adherence to GDM treatment, and no breastfeeding six weeks after delivery.
  
  
  CONCLUSIONS
  GTT performed six weeks after delivery increases the adherence to the test. The factors associated with non-adherence are more related to personal matters than to GDM.
