“My husband and I want to have a baby.
Do you have any advice before I get pregnant?”




 What are the goals of this initial visit?

                                          NEXT
      Goals of Preconception Care
   Identify modifiable and non-modifiable risk factors for
    poor obstetrical outcomes before conception begins.
   Provide an opportunity to intervene when modifiable
    risk factors are identified and provide truly preventive
    care before conception.
   Perform individualized patient education including
    information on the advantages of planned pregnancy.

    What risk factors come to mind for Amy?
                                                       NEXT
     Identifying Risk Factors
Amy T is a healthy young female but she does present a
  few worrisome risk factors for a complicated
  pregnancy:
 Smoking

 Occasional use of alcohol

 Family history of hypertension




During typical preconceptional counseling,
what types of risk should be focused on in
the patient’s history?

Social or Demographic Risk Factors
      Click on the following bullets for more information regarding risk

Which are the more concerning age groups?
   Teenagers
   >35 years old

   Father is >55 years old

   All of the above

    Risks Associated with Smoking
   Amy is a smoker, and has had trouble quitting in
    the past. She would like to know what risks she
    carried if she continues to smoke. Which of the
    following is true?
     Increased risk of placenta previa and placental
      abruption
     Increased risk of macrosomia

     Increased risk of birth defects

     None of the above
Incorrect!



  GO BACK…
                      Correct!
         Risks Associated with Smoking
   Statistics
        In the US more than 20% of women smoke.
        At least 11% of women smoke during pregnancy
   Smoking harms the fetus/newborn:
        Nearly doubles the risk of microsomia: In 2002 12.2% of babies born to smokers
         in the US were of low birth weight compared to 7.5% of babies of nonsmokers.
        May be a 3x risk for SIDS
   Smoking effects pregnancy:
        May double the risk of placenta previa and placental abruption.
        May increase the risk of PROM and PPROM.
        May increase risk of premature delivery.
   Fertility
        May be an increase risk for female infertility when compared to nonsmokers.

    Now Amy is worried. She has a friend who is
  pregnant and smoking. Amy wonders if she has
already harmed the baby- is it even worth quitting at
                    this point?

         If a woman stops smoking by the end of her first trimester of
     pregnancy she is no more likely to have a low birth weight baby than a
                         woman who never smoked.

                  In 1999, 12.8% of pregnant women reported having had at least one drink during
                   pregnancy. 2.7% reported drinking more than 5 drinks on one occasion. 3.3% reported
                   drinking more than 7 drinks per week.
           No level of alcohol use during pregnancy has been proven safe.
      Risks

Risks Associated with Caffeine
      Statistics
          Strong evidence for a correlation between caffeine intake and
           complications during pregnancy is lacking.
      Risks
          Evidence may suggest that as little as one average cup of
           coffee a day (~150 mg of caffeine) may be associated with
           increased risk of spontaneous abortion, preterm delivery, and
           microsomia.
          Infertility
               >300mg of caffeine per day may delay conception by a year or more.

Risks Associated with Cocaine Use
      Statistics
           Since the mid-1980s, about 1 million babies have been born to mothers who used cocaine
            during pregnancy.
      Risks
           Spontaneous abortion
           Stroke of mother or child
           MI of mother or child

           Delayed motor skills
           May adversely effect learning, behavior, and language abilities.

  Risks Associated with Marijuana
      Risks
          Difficult to determine due to other confounders.
               Women who use marijuana also use tobacco, alcohol, or other drugs.
               Lower socioeconomic class may be another confounder.
          Microsomia
          Currently no teratogenic effect has been documented
          Higher risk of meconium staining
               57% in users vs. 25% in non-users

 Risks Associated with Herbal
         Supplements
   Statistics
          More than 60 million Americans report using herbal supplements
          Accounts to $3-4 billion in out-of-pocket expense
          There are over 400 herbs used widely and distributed as capsules, extracts, tablets, and teas.
   Risks
          Few studies have been conducted testing herbal preparations in pregnancy.
          Herbs are considered dietary supplements and thus aren’t controlled by the FDA.
                Manufacturers of herbs aren’t required to prove effectiveness or safety of their products.
                There are no standard quality controls. As a result, the composition of herbal products may vary greatly from one
                 batch to another.
                Reports of herbal supplements being contaminated with lead or other substances have been reported.
                Complications associated with herbal supplements include stimulation of uterine contractions which may result in
                 miscarriage or preterm labor.
          Patients assume herbal supplements are safe and often do not inform their physicians of their use.

   The National Institute of Health’s National Center for Complementary and Alternative Medicine
    (NCCAM) is currently studying the safety and effectiveness of a number of herbal remedies. The
    results of these studies should help clarify who can benefit from these products.

   Current recommendation of the March of Dimes organization is for physician discretion. All
    patients must be asked about herbal supplements and informed about the risk.

            Risks Associated with
             Domestic Violence
      Statistics
           About 1.5 million women are abused each year
                   Includes physical or sexual abuse, threats, and psychological or emotional abuse.
                   Affects as many as 324,000 pregnant women each year
                   May actually be more common than conditions that are routinely screened such as gestational
                    diabetes and hypertension.
      Risks
           Direct effects
                   Spontaneous abortion
                   Fetal injury or death from maternal trauma
           Indirect effects
                   Maternal stress
                   Maternal drug abuse including smoking, and alcohol.
      Screening
           96% of pregnant women receive some type of prenatal care and average 12-13 visits.
            Excellent opportunities to screen for abuse.
           An Abuse Assessment Screen should be performed at the initial prenatal visit and at least
            once per trimester. The conversation should be well documented.
           Make appropriate referrals immediately if there is a concern. (ie Law enforcement, shelters,
            local hotlines, and office or hospital staff with special training.)

        Abuse Assessment Screen
1. In the last year (since I saw you last), have
    you been hit, slapped, kicked, or otherwise
    physically hurt by someone? (If yes, by
    whom? Number of times? Nature of injury?)
2. Since you’ve been pregnant, have you been
   hit, slapped, kicked, or otherwise physically
   hurt by someone? (If yes, by whom?
   Number of times? Nature of injury?)
3. Within the last year has anyone made you do
   something sexual that you didn’t want to do?
   (If yes, who?)

4. Are you afraid of your partner or anyone
   else?

         Risks and Recommendations:
   Statistics
                   Diabetes
         17 million people have some form of diagnosed diabetes in the U.S. Another 6 million may be undiagnosed.
         Approximately 4-6% of pregnancies are complicated by diabetes.
              90% of these are gestational diabetes and the rest is preexisting.
   Risks
         Poorly controlled diabetes (HbA1c >8.4) is associated with:
              32% rate of spontaneous abortion
              7x increase risk of severe fetal anomalies.
