1. Why the Focus on Early Nutrition?

Preconception Care in the United States & Europe – 2025 Evidence‑Based Overview

Preconception illustration

The pre‑conception window is the most effective period to improve health, reduce pregnancy complications, and optimise fetal development.
Early risk screening, lifestyle modification, and vaccination can markedly lower rates of neural‑tube defects, preterm birth, and low‑birth‑weight infants.

10‑point recommendation covering personal responsibility, public outreach, pre‑conception exams, insurance coverage, etc., focusing on risk assessment, nutrition, chronic disease management, immunisation, mental health.
Key actions:
1. Annual pre‑conception health assessment for all reproductive‑age women (blood glucose, BP, BMI, medication review).
2. Folic acid 400 µg/day for at least one month before conception.
3. Vaccinations: MMR, influenza, hepatitis B, COVID‑19 (if indicated).
4. Behavioural interventions: smoking cessation, alcohol limitation, weight management, regular exercise.
5. Insurance policies: Medicaid and private insurers encouraged to reimburse one annual pre‑conception visit.

Policy heterogeneity: Belgium (Flanders), Denmark, Italy, Netherlands, Sweden, United Kingdom differ in nutrient recommendations, alcohol/caffeine limits, vitamin supplementation.
Common consensus:
- Nutrition & lifestyle: balanced diet, moderate fish intake, caffeine < 200 mg/day, alcohol < 1 unit/day.
- Chronic disease control: diabetes, thyroid disease, obesity must be optimised before conception.
- Psychosocial screening: depression, intimate‑partner violence, social support assessment with referral pathways.
Implementation gaps: low guideline adherence, lack of EU‑wide standards, insufficient public awareness—calls for a harmonised EU framework.

Domain	Recommended Measures	Evidence
Nutrition	Folic acid 400 µg/day; iron, iodine, vitamin D supplementation; ≥ 5 food groups daily
Lifestyle	Quit smoking, limit alcohol, caffeine < 200 mg/day, ≥ 150 min moderate exercise weekly
Chronic Disease	Diabetes HbA1c < 6.5%; BP < 130/80 mmHg; BMI 18.5‑24.9
Vaccination	MMR, influenza, hepatitis B, COVID‑19 (if indicated)
Psychosocial	PHQ‑9 depression screen, IPV assessment, connect to social support services
Male Involvement	Health check, semen analysis, lifestyle optimisation, genetic counseling (though no dedicated guidelines)

Define a reproductive plan – set desired number of children and timeline; record in a family‑planning calendar.
Schedule a pre‑conception exam – CBC, fasting glucose, BP, thyroid panel, serum folate, infectious disease immunity.
Start folic acid – 400 µg daily (800 µg if personal/family history of NTD).
Adjust lifestyle – quit smoking, limit alcohol, keep caffeine ≤ 200 mg/day, achieve BMI 18.5‑24.9, exercise ≥ 150 min/week.
Check immunisations – verify MMR, flu, hepatitis B, COVID‑19 status; receive missing doses.
Control chronic conditions – meet target metrics for diabetes, hypertension, thyroid, lipid profile before trying to conceive.
Mental health screening – complete PHQ‑9/GAD‑7; seek professional help if scores indicate depression or anxiety.
Male health – physical exam, semen analysis, quit smoking, limit alcohol, consider zinc & folic acid (400 µg) supplementation to improve sperm quality.

U.S.: CDC Preconception Health website, PRAMS, NSFG, HEDIS metrics.
Europe: ECDC pre‑conception reports, national health services (NHS, KCE, RIVM) guidelines, EU‑HIS monitoring system.
Global: WHO Preconception Care policy brief (2013) provides a framework for national action.

The U.S. has a relatively comprehensive ten‑point framework emphasizing systematic risk screening, insurance coverage, and public outreach.
Europe possesses rich country‑specific expertise but suffers from fragmented guidelines; a coordinated EU‑wide standard is urgently needed.
For couples, nutrition, lifestyle, chronic disease management, immunisation, and mental health are the five pillars of successful pre‑conception care—both partners must actively participate to improve pregnancy outcomes.
