ABSTRACT
This study tested the hypothesis that to reduce the rate of macrosomic infants in gestational diabetes cases, good glycemic control should be initiated before 34 completed gestational weeks. The study population included 84 women with gestational diabetes, ascertained by universal screening of all women attending the antenatal clinic of the Hadassah Medical Center, over a 2-year period. The 60 women (71%), who initiated treatment before 34 completed weeks, composed the “early” group. The 24 women (29%), who initiated treatment after the 34th week, composed the “late” group. All patients were managed by an intensified protocol, including stringent glycemic control. In the “early” and “late” groups, mean gestational age at the beginning of treatment was 30.0±3.8 and 36.2±1.2 weeks, and duration of treatment was 9.6±4.1 and 3.7±1.8 weeks, respectively. Maternal characteristics were similar in the two groups. The rate of macrosomic and large-for-gestational-age infants were 5 and 11%, respectively, in the early group as compared to 25 and 29% in the “late” group (p < 0.05). No significant differences were found between the two groups in the mode of delivery or Apgar scores. We conclude that to reduce the rate of macrosomic infants in gestational diabetes cases, good glycemic control should be initiated before 34 completed gestational weeks.
