Abstract

Aims To test the common assumption that pregnant women who are sufficiently motivated to achieve very good HbA(1c) levels will record home blood glucose data accurately. Methods A new device was used to download information from electronic blood glucose meters to assess the extent of selectivity in patient glucose diary-keeping. Results In an index case, a woman with excellent ambient HbA(1c) (5.9%; upper limit of normal 6.1%) was observed to have 68% of preprandial blood glucose readings above the target range of 3.5-6.5 mmol/l and a mean (+/-SD) level of 8.9 +/- 3.9 mmol/l in the corresponding period. No such impression was conveyed by the home monitoring diary. Six pregnant women with well controlled Type I diabetes (mean HbA(1c) 6.6 +/- 0.2%) exhibited between 42 and 68% of preprandial readings above the target range. Conclusions The frequency of hyperglycaemia has hitherto been underestimated in well controlled pregnant women whose near-perfect home monitoring record is apparently corroborated by near-normal HbA(1c), levels. These observations provide a hypothesis for understanding of the disappointing continuance of macrosomia despite excellent HbA(1c) levels throughout pregnancy.
