What is the importance and recommended protocol for a pre-conception (before pregnancy) check-up?

Importance and Protocol for Pre-Conception Check-Up

Pre-conception care is essential for optimizing maternal and fetal health outcomes by identifying and modifying biomedical, behavioral, and social risks before pregnancy occurs. 1 This care is critical because many risk factors affect fetal development early in pregnancy, often before women know they are pregnant or enter prenatal care.

Who Should Receive Pre-Conception Care

• Every woman of reproductive age capable of becoming pregnant is a candidate, even if not planning to conceive 1
• Men should also receive pre-conception care, though components are less well-defined 1
• Care should be integrated into routine primary and preventive visits rather than being an isolated visit 1

Key Components of Pre-Conception Assessment

Medical History and Physical Examination

• Reproductive history: Previous adverse pregnancy outcomes (fetal loss, birth defects, preterm birth) 1
• Medical conditions: Assess and optimize management of chronic conditions:
  • Diabetes (aim for A1C as close to normal as possible) 1
  • Hypertension
  • Thyroid disorders
  • Autoimmune diseases
  • Cardiac disease 1
• Physical examination focusing on:
  • Periodontal health
  • Thyroid
  • Heart
  • Breast
  • Pelvic examination 1

Laboratory Testing

• Complete blood count
• Urinalysis
• Blood type and screen
• Screening for:
  • Rubella immunity
  • Syphilis
  • Hepatitis B
  • HIV
  • Gonorrhea
  • Chlamydia
  • Diabetes
  • Cervical cytology
  • Thyroid-stimulating hormone levels when indicated 1

Risk Assessment and Screening

Genetic Screening

• Assess risk of chromosomal/genetic disorders based on:
  • Family history
  • Ethnic background
  • Age
• Offer carrier screening for conditions like cystic fibrosis when indicated 1

Medication Review

• Identify and discontinue teratogenic medications (FDA category X)
• Review all prescription, over-the-counter medications, herbs, and supplements
• For chronic conditions, switch to safer medications when possible 1

Substance Use Assessment

• Screen for tobacco, alcohol, and drug use
• Use validated tools like CAGE or T-ACE questionnaires 1

Psychosocial Assessment

• Screen for depression, anxiety, domestic violence, and major stressors 1

Nutritional Assessment

• Evaluate BMI (ideal range: 19.8-26.0 kg/m²)
• Assess for nutritional deficiencies
• Evaluate dietary habits 1

Key Interventions

Nutritional Interventions

• Prescribe daily folic acid supplementation (400 mcg) to prevent neural tube defects 1, 2
• Recommend prenatal vitamins with at least 400 mcg folic acid and 150 mcg potassium iodide 1
• Promote healthy diet with adequate fruits and vegetables 1
• Address weight management for women who are underweight, overweight, or obese 1, 3

Immunization Updates

• Update as needed:
  • Hepatitis B
  • Rubella
  • Varicella
  • Tdap (tetanus, diphtheria, pertussis)
  • HPV
  • Influenza 1, 2

Disease Management

• Diabetes: Optimize glycemic control before conception to reduce congenital anomalies 1
• Hypertension: Review medications (avoid ACE inhibitors and ARBs) 1
• Thyroid disorders: Ensure proper management 1, 2
• Epilepsy: Review and adjust anticonvulsant medications if needed 2

Lifestyle Modifications

• Smoking cessation
• Alcohol cessation
• Substance use cessation
• Avoidance of environmental toxins and teratogens 1, 2, 4

Implementation Strategy

1. Ask about reproductive life plans at every visit with women of reproductive age 1
2. If planning pregnancy within 1-2 years, schedule comprehensive assessment
3. If not planning pregnancy, provide contraceptive counseling and continue routine care 1
4. For women with chronic conditions, manage in multidisciplinary setting when available 1

Common Pitfalls to Avoid

• Waiting until pregnancy is confirmed: By then, critical periods of organogenesis may have passed 1
• Focusing only on women actively planning pregnancy: About half of all pregnancies in the US are unintended 4
• Neglecting underweight women: They require the same level of counseling as overweight women but often receive less 3
• Overlooking environmental exposures: Workplace and household toxins should be identified and avoided 1
• Inadequate medication review: Some medications must be changed before conception, not after pregnancy is confirmed 1

Pre-conception care represents a critical window of opportunity to improve both maternal and child health outcomes 5, 6. By systematically addressing modifiable risk factors before pregnancy occurs, healthcare providers can significantly reduce the risk of adverse pregnancy outcomes and promote long-term health for both mother and child.
