What components should be included in a preconception evaluation for a woman planning pregnancy?

Preconception Checkup Components

A preconception checkup should systematically address folic acid supplementation (400-800 mcg daily), chronic disease optimization, medication safety review, immunization status, lifestyle risk assessment (tobacco, alcohol, drugs), mental health screening, reproductive planning discussion, and weight optimization. 1

Core Assessment Areas

Folic Acid and Nutrition

• All women of reproductive age must take 400-800 mcg of folic acid daily, starting before conception through 12 weeks of pregnancy 1
• Women at high risk for neural tube defects require higher doses
• Counsel on consuming folate-rich foods as part of a balanced diet

Chronic Disease Management

The following conditions require optimization before conception to reduce maternal and fetal morbidity:

Diabetes mellitus:

• Target A1C <6.5% before pregnancy to minimize congenital anomalies 2
• Counsel on importance of glycemic control 1

Hypertension:

• Check blood pressure during routine care
• Switch to pregnancy-safe antihypertensive medications 1

Mental health disorders:

• Screen for depression and anxiety disorders
• Counsel about risks of untreated illness during pregnancy
• Adjust medications before conception if appropriate 1
• Note: Mood and anxiety disorders are highly prevalent in women of reproductive age with high relapse rates during pregnancy 1

Medication Review

• Assess all current medications for teratogenic potential 1
• Switch to safer alternatives before conception when necessary
• Many commonly prescribed medications are unsafe in pregnancy 1

Weight Optimization

• Women with BMI ≥30 kg/m² or <18.5 kg/m² should be counseled about infertility risks and pregnancy complications 1
• Target BMI 18.5-24.9 kg/m² reduces complications 2
• For bariatric surgery patients: delay pregnancy at least 12 months post-procedure and ensure adequate nutritional status 2

Lifestyle Risk Assessment

Screen and counsel on:

• Tobacco use - impacts partner's pregnancy directly 1
• Alcohol consumption 1
• Illicit drug use 1
• Environmental exposures 2

Immunization Status

• Review and update immunizations annually 1
• Prevents adverse outcomes related to infections 2

Infectious Disease Screening

• Assess STI risk for both partners 1
• Provide testing and treatment as needed
• Update screenings before conception to allow for treatment, prophylaxis, or pregnancy timing 2

Reproductive Planning Discussion

• Discuss reproductive goals at each visit - plans may change with life circumstances 1
• When pregnancy desired: discuss medications, health conditions, and activities affecting fertility 1
• When pregnancy not desired: offer full range of FDA-approved contraceptive methods 1
• Counsel on importance of birth spacing 1

Family and Genetic History

• Assess pregnancy risks based on maternal age, maternal and paternal health conditions, obstetric history, and family history 1

Violence Screening

• Screen all women for current, recent past, or childhood physical, sexual, or emotional interpersonal violence 1
• Refer to appropriate resources when needed

Male Partner Considerations

Men's health directly impacts pregnancy outcomes:

• Diabetes mellitus, erectile dysfunction, and testicular conditions affect fertility 1
• Tobacco smoking and STIs directly impact partner's pregnancy 1
• Counsel on contraception, fertility issues, and healthy lifestyle choices 1

Common Pitfalls to Avoid

• Don't wait for a dedicated preconception visit - integrate these discussions into routine gynecologic care as an ongoing process 3
• Don't assume planned pregnancy - many pregnancies are unplanned, so folic acid supplementation should be universal for all reproductive-age women 1, 2
• Don't overlook the male partner - his health and lifestyle factors directly affect pregnancy outcomes 1
• Start early - many interventions require weeks to months to be effective, so counseling should begin well before discontinuing contraception 3
