Rationale:
- There is an association between elevated maternal glucose or glycohemoglobin levels during embryogenesis and high rates of
pregnancy loss and major congenital malformations.
|
|
Evidence:
- In a meta-analysis of 14 cohort studies, the pooled rates of major and minor fetal anomalies were lower in diabetic women
who had received pre-conception care (2.1%) compared with those who had not (6.5%; RR 0.36 [CI, 0.22 to 0.59]) (1).
- Population-based cohort studies have found an association between adverse fetal outcomes and maternal hyperglycemia (2; 3).
|
|
Comments:
- Pre-conception counseling also should include advice on folic acid intake, vaccinations for rubella and varicella, weight
control, and a review of current diseases and medications in addition to an assessment of diabetes management.
