Recommendations for Preconception Care

    Every woman of reproductive age who is capable of becoming pregnant is a candidate for pre-
    conception care, regardless of whether she is planning to conceive. Preconception care is aimed
    at identifying and modifying biomedical, behavioral, and social risks through preventive and
    management interventions. Key components include risk assessment, health promotion, and
    medical and psychosocial interventions. Patients should formulate a reproductive life plan that
    outlines personal goals about becoming pregnant based on the patients values and resources.
    Preconception care can be provided in the primary care setting and through activities linked
    to schools, workplaces, and the community. (Am Fam Physician 2007;76:397-400. Copyright

  Table 1. Summary of the CDC/ATSDR Guideline on Preconception Care
  Consumer awareness: Increase public awareness about the importance of preconception health behaviors and care services by using
   information and tools that are appropriate across various age groups, literacy levels (including health literacy), and cultures/languages
  Health insurance coverage for women with low incomes: Increase public and private health insurance coverage for women with low
   incomes to improve access to preventive womens health and pre- and interconception care
  Individual responsibility across the life span: Encourage each woman, man, and couple to have a reproductive life plan (i.e., a plan, based
    on the patients values and resources, to achieve a set of personal goals about having children)
  Interconception care: Use the interconception period to provide additional intensive interventions to women who have had a previous
    pregnancy that ended in an adverse outcome (e.g., infant death, fetal loss, birth defects, low birth weight, preterm birth)
  Interventions for identified risks: Increase the proportion of women who receive interventions as follow-up to preconception risk
    screening, focusing on high-priority interventions (i.e., those with evidence of effectiveness and the greatest potential impact)
  Monitoring improvements: Maximize public health surveillance and related research mechanisms to monitor preconception health
  Prepregnancy checkup: As a component of maternity care, offer one prepregnancy visit for couples and persons planning pregnancy
  Preventive visits: As a part of primary care visits, provide risk assessment, education, and health promotion counseling to all women of
    childbearing age
  Public health programs and strategies: Integrate components of preconception health care into existing local public health and related
    programs, including an emphasis on interconception interventions for women with previous adverse pregnancy outcomes
  Research: Increase the evidence base and promote the use of the evidence to improve preconception health
