Background and Clinical Problem: Preconception Counseling
|
|---|
Diabetes has been associated with pregnancy-related
complications.1,2
Rates of spontaneous abortion and perinatal mortality and the incidence of
congenital anomalies in offspring of women with diabetes remain significantly
higher than that of the background population. It is well accepted that
achieving a level of glycemic control comparable to the nondiabetic population
can decrease the incidence of adverse pregnancy outcomes. The American
Diabetes Association
(ADA)1 and the
American College of Obstetricians and
Gynecologists2 both
recommend preconception counseling (PC) for all women with diabetes who have
child-bearing potential.
The ADA1
recommends that PC include the risks of congenital malformations associated
with poor metabolic control and the use of effective contraception unless the
woman is in good metabolic control. The goal for glycemic management is to
obtain the lowest possible hemoglobin A1c (A1C) level without undue
risk of hypoglycemia, preferably an A1C that is < 1% above the normal
range. It is also recommended that providers identify and treat complications
of diabetes, such as nephropathy, retinopathy, hypertension, coronary artery
disease, and neuropathy, before
conception.3
The majority of women with diabetes, however, do not obtain PC and continue
to have unplanned pregnancies. The majority of studies
(Table
1)4,5,7–19
report that up to 62% of women with type 1 diabetes received PC, whereas <
36% of women with type 2 diabetes received PC. In studies by Gunton et
al.,4,5
the rate of women with type 1 diabetes having received PC improved
significantly over time (from 18.9 to 62.5%), but a downward trend was noted
in the rate for women with type 2 diabetes (from 52.6 to 36.4%). . . . [Full Text of this Article]
