What Are What Are ““High RiskHigh Risk”” Conditions?Conditions?
• In this module, high risk conditions are defined as preexisting medical diseases which could result in compromised health for the woman, the fetus or the offspring should pregnancy occur.
• In subsequent modules, other definitions of high risk conditions, such as previous poor pregnancy outcome, will be explored
Next
The Rationale for Targeting Preconception Care To Women with
High Risk Conditions• Nearly 50% of pregnancies are conceived without intent• Even when pregnancy is intended, women may not have
discussed their desire or plans to conceive with their medical provider
• Women with high risk conditions frequently have contact with medical providers
• Medical providers often overlook the ramifications of pregnancy as they address a woman’s chronic disease needs
• Therefore overlooked opportunities may exist to reach women with important information on high risk conditions and their potential impact on maternal, fetal or newborn health
Next
The Role of the Clinician in Preconception Care
• Consider every visit as an opportunity to address preconception needs to:– Prevent unwanted/unintended pregnancies
– Provide preconception counseling, if pregnancy is desired
– Encourage women/couples to actively choose when and when not to become pregnant
– Provide general health promotion and disease prevention guidance

Evidence-based Recommendations on Preconception Care for Women with Diabetes
Mellitus
All women with diabetes mellitus should be counseled about the importance of diabetes mellitus control before considering pregnancy. Important counseling topics include achieving optimal weight, maximizing diabetes control, self glucose monitoring, a regular exercise program and tobacco, alcohol and illicit drug-use cessation along with social support to assist during pregnancy.
Strength of evidence: A Quality of evidence: INext
Evidence-based Recommendations on Preconception Care for Women with
Diabetes Mellitus
• In the months before pregnancy, women with diabetes mellitus should demonstrate as near-normal glycosylated hemoglobin levels as possible (while avoiding hypoglycemia) for the purpose of decreasing the rate of congenital anomalies. Women with poor control should be encouraged to use effective birth control.
