Pre-conception Care
Concepts of pre-pregnancy care
• Definition: Is “a set of interventions that aim to identify and modify
biomedical, behavioral, and social risks to a woman’s health or pregnancy
outcome through prevention and management.”(CDC 2015)
• This care has also been called pre-pregnancy, inter-pregnancy care, or
periconceptional medicine.
11/26/2023 DAJANE N.(BSc, MSc) 3
Terminologies
Preconception
The period of time before the fertilization of an ovum
Pre-pregnancy
Sometimes used in place of preconception as it is considered to be
easier for the general public to understand.
It refers to the period of time before a person becomes pregnant
11/26/2023 DAJANE N.(BSc, MSc) 4
Terminologies
Periconception period:
• Is the time window of 14weeks prior to conception until 10 weeks
after conception.
the gametes maturate and are epigenetically programmed
the embryonic tissues, organs and trophoblast (placenta) are
formed.
11/26/2023 DAJANE N.(BSc, MSc) 5
Terminologies
Preconception health
The health of women and men during their reproductive years,
which are the years they can become pregnant.
All women and men can benefit from preconception health,
whether or not they plan to have a baby 1 day.
Part of preconception health is about people getting and staying
healthy overall, throughout their lives
11/26/2023 DAJANE N.(BSc, MSc) 6
Terminologies
Preconception health …
Good preconception health encompasses two main concepts:
i. Planning pregnancy
Enabling women and their partners to choose if and when to start
or grow their families
ii. Fit for pregnancy
Recognizing that many pre-pregnancy health behaviours and risk
factors are amenable to change

Terminologies
Inter-conception care
Is the provision of preconception care in between the birth of one
child and the conception of the next child
• Is an opportunity to :assess risk, promote healthy, assess lifestyle
behaviors;
• identify and treat medical and psychosocial issues that could
impact pregnancy outcome.
11/26/2023 DAJANE N.(BSc, MSc) 9
Aim : Preconception care
Improve knowledge, attitudes, and behaviors of men and women
related to pre-conceptional health
Assure that all childbearing-aged women receive pre-conceptional
care services
including evidence-based risk screening, health promotion, and
interventions will enable them to enter pregnancy in optimal
11/26/2023 health DAJANE N.(BSc, MSc) 10
Aim: cont’d
Reduce risks indicated by a previous adverse pregnancy outcome through
inter-conceptional interventions to prevent or minimize recurrent adverse
outcomes
Reduce the disparities in adverse pregnancy outcomes
potentially modifiable condition(factors)
pregnancy outcomes are dependent on the interaction of various maternal, fetal,
and environmental factors
11/26/2023 DAJANE N.(BSc, MSc) 11
During the inter-conception period:
intensive interventions are provided to women who have had a
previous adverse pregnancy outcome
• fetal loss
• preterm birth (PTB)
• low birthweight (LBW)
• birth defects, or infant death.
• Specifically, for those planning pregnancy
11/26/2023 DAJANE N.(BSc, MSc) 12
Interconception period
Addressing the health of women and their partners prior to
pregnancy
recognised as an essential element to achieve healthy outcomes
for mothers and their children
11/26/2023 DAJANE N.(BSc, MSc) 13
Pre-conception Care: Goal
Is to identify and modify biomedical, behavioral, and social risks to the
woman's health or pregnancy outcome through prevention and management. Or
Generally, its goal is to enhance pregnancy outcomes and improve child health.
Preconception care can help reduce the risk of complications during pregnancy
and childbirth, improve the health of the mother and baby, and increase the
chances of having a healthy baby.
The interventions include education, counseling, and assessment.
11/26/2023 DAJANE N.(BSc, MSc) 14
Pre-conception Care
• Education includes topics such as smoking, alcohol abuse, and
other drug use, folic acid supplementation, and healthy diet.
• Counseling includes topics such as sexually transmitted
infections, family planning, and pregnancy spacing.
• Assessment includes physical examination, medical and family
history, and carrier screening.
• Preconception care is beneficial for all people, whether or not
they plan to have a baby one day.

11/26/2023 DAJANE N.(BSc, MSc) 16
PCC involves a range of strategies including:
Reproductive planning
• the use of effective contraception before conception is desired
counseling regarding substance use in pregnancy
• avoidance of smoking and alcohol consumption
folic acid and iodine supplementation
weight reduction in those overweight or obese and
Medication adjustments.
11/26/2023 DAJANE N.(BSc, MSc) 17
Why is the preconception care?
11/26/2023 DAJANE N.(BSc, MSc) 18
Why PCC…
• There is a growing recognition that adolescent pregnancies and poorly
spaced pregnancies contribute to maternal, perinatal and infant
mortality, and the vicious cycle of ill-health and poverty.
11/26/2023 DAJANE N.(BSc, MSc) 19
Why PCC..
Globally four out of 10 women report that their pregnancies are
unplanned.
Perinatal deaths are 50% higher among babies born to adolescent
mothers
Women with epilepsy are at increased risk of having babies with
congenital anomalies.
Maternal malnutrition plays great role in maternal mortality
11/26/2023 DAJANE N.(BSc, MSc) 20
Why PCC..
Preconception care
provides a full range of effective interventions
• focused primarily on the health of women of reproductive age, and
• their partners, prior to or between pregnancies,
promote the opportunity for safe motherhood and the birth of a healthy
infant with the expectation of healthy longevity
11/26/2023 DAJANE N.(BSc, MSc) 21
Why PCC..
brings attention to the missing component in the existing health
system
addressing the needs of adolescents, young women and their partners
before pregnancy is planned or occurs
11/26/2023 DAJANE N.(BSc, MSc) 22
Why PCC..
Has positive impact
reduce maternal and child mortality
prevent unintended pregnancies
prevent complications during pregnancy and delivery
prevent stillbirths, preterm birth and low birth weight
11/26/2023 DAJANE N.(BSc, MSc) 23
Why PCC..
prevent birth defects
prevent neonatal infections
prevent underweight and stunting
prevent vertical transmission of HIV/STIs
lower the risk of some forms of childhood cancers
lower the risk of type 2 diabetes and cardiovascular disease later in
life.

# Why is the preconception period important?
11/26/2023
DAJANE N.(BSc, MSc) 26
Why is PC period…
The periconception environment is critically important for the
developmental process
Poor maternal health and diet before and in the early stages of pregnancy
can lead to;
impaired fetal or infant growth
poor birth outcomes
11/26/20
23
long-term effects on cardiovascular
DAJANE N.(BSc, MSc) and metabolic disease 27
Why is PCC…
Fetal programming:
the intrauterine environment is understood to have a profound impact on
one’s entire lifetime health
i.e. is known as the developmental origins of health and disease
(DOHAD).
• E.g. The offspring of mothers who are obese at the time of conception are
more likely to be overweight and develop cardiovascular and metabolic
disease

Pre-pregnancy health and Planning for pregnancy
• Pre-pregnancy planning:
o It is essential to ensure a healthy pregnancy and promote the well-
being of both you and your future baby.
• Here are some steps to consider before getting pregnant: find the next
slides.
11/26/2023 DAJANE N.(BSc, MSc) 32
Pre-pregnancy health and Planning for pregnancy
• Schedule a Preconception Visit:
• As soon as you’re ready to try for pregnancy, visit your healthcare
provider for a preconception checkup.
• During this visit, discuss on:
• medical history
• family’s medical history
• current health issues, diet, vitamins,
• lifestyle, safety of medications, and mental health.
• dental checkup to address any
11/26/2023 DAJANE gum
N.(BSc, MSc)disease before pregnancy 33
Cont’d…
• Genetic Counseling:
• Consider meeting with a genetic counselor if you have
concerns about genetic conditions or family history.
• Genetic counseling helps assess your risk and provides
information about potential genetic disorders.
11/26/2023 DAJANE N.(BSc, MSc) 34
Cont’d…
• Start Taking Prenatal Vitamins:
• Begin taking prenatal vitamins that contain folic acid before
conception.
• Folic acid helps prevent birth defects of the brain and spine.
• Give Up Bad Habits:
• If you smoke, drink alcohol, or use recreational drugs, seek help to quit.
• These substances can harm your health and affect fetal development.
11/26/2023 DAJANE N.(BSc, MSc) 35
Cont’d…
• Eat Well:
• Focus on a balanced diet rich in fruits, vegetables, whole grains, lean
proteins, and dairy products.
• Proper nutrition supports your health and prepares your body for
pregnancy.
• Aim for a Healthy Weight:
• Achieve and maintain a healthy weight before pregnancy.
• Being underweight or overweight can impact fertility and pregnancy
outcomes.
11/26/2023 DAJANE N.(BSc, MSc) 36
Cont’d…
• Establish a Regular Exercise Routine:
• Engage in moderate exercise to improve overall fitness.
• Consult your healthcare provider for exercise recommendations.
• Mental Health:
• Manage stress, practice relaxation techniques, and seek emotional
support.
• Mental well-being is crucial during preconception and pregnancy.
• Remember that pre-pregnancy care helps identify any issues that could
affect your pregnancy, allowing you to take preventive steps.
11/26/2023 DAJANE N.(BSc, MSc) 37
Time to initiate preconception care
• The time that people should start caring for a pregnancy is before conception.
• Preconception care should occur any time any health care provider sees a
reproductive-age patient
• occur opportunistically when women of childbearing age attend their health
care professional for;
contraception or for baby and toddler checks
attend their specialist for review of their medical disease or
if they are referred to infertility clinics.
11/26/2023 DAJANE N.(BSc, MSc) 38
Time to initiate preconception care
Here are some key points to consider:
• Planning Ahead:
• Preconception care involves preparing for a healthy pregnancy.
• It’s beneficial to start thinking about it at least three months before
actively trying to conceive.
• However, even if a woman is already pregnant, it’s never too late to
begin preconception care.
11/26/2023 DAJANE N.(BSc, MSc) 39
Time…cont’d
• Before Conception:
• Optimal health before pregnancy significantly impacts the health
of both the mother and the baby.
• Starting preconception care early allows time to address any health
issues, make lifestyle changes, and optimize overall well-being.
11/26/2023 DAJANE N.(BSc, MSc) 40
Time…cont’d
• Key Considerations:
• Medical Conditions: If a woman has any existing medical
conditions (such as diabetes, hypertension, or thyroid disorders),
managing them before pregnancy is crucial.
• Medications: Review medications and adjust them if necessary.
Some medications may need to be changed during pregnancy.
11/26/2023 DAJANE N.(BSc, MSc) 41
Time…cont’d
• Key Considerations:
• Nutrition: Ensuring adequate folic acid intake and a balanced diet is
essential.
• Lifestyle Factors: Addressing factors like smoking, alcohol
consumption, and substance use is vital.
• Immunizations: Checking immunization status and getting necessary
vaccines (e.g., rubella) is important.
• Genetic Screening: Assessing genetic risks and considering carrier
screening if relevant.
11/26/2023 DAJANE N.(BSc, MSc) 42
Time…cont’d
• Consulting a Healthcare Provider:
• Women planning pregnancy should schedule a visit with their
healthcare provider.
• The provider will assess overall health, discuss family history, and
provide personalized recommendations.
11/26/2023 DAJANE N.(BSc, MSc) 43
Time…cont’d
• Early Pregnancy Care:
• If a woman suspects she might be pregnant, she should seek prenatal care
promptly.
• Early prenatal visits help monitor the pregnancy and address any issues.
• Note: preconception care sets the foundation for a healthy pregnancy and a
healthy baby.
• Open communication with a healthcare provider is essential throughout the
process.

# What PCC interventions improve maternal and fetal outcomes?
11/26/2023 DAJANE N.(BSc, MSc) 45
women and their partners who receive PCC are more likely to have
improved knowledge and show positive health behaviours:
Decreased smoking and consumption of any substance abuse
increased use of folic acid and
greater engagement in antenatal care
11/26/2023 DAJANE N.(BSc, MSc) 46
Elements of preconception care actions and counseling
Reproductive planning
• Reproductive planning helps to prevent unintended pregnancy, age-related
infertility and fetal teratogen exposure.
• It may also improve health and pregnancy outcomes.
• Arrange preconception visit schedule for those desiring pregnancy
• Offer appropriate contraception advice for those not desiring pregnancy or
until chronic medical conditions are stabilized.

preeclampsia, and fetal death
Risk of worsening hypertension and organ damage
11/26/2023 DAJANE N.(BSc, MSc) 71
Medical history…
Hypertension
Caring for women of reproductive age with hypertension should include:
• Educating them about the risks of hypertension during pregnancy
and
• Their medication regimen may need to be changed before
conception.
• Women with long-standing hypertension
assessed for retinopathy,
11/26/2023 renal disease, and ventricular
DAJANE N.(BSc, MSc) hypertrophy 72
Medical history…
Hypertension
Angiotensin converting enzyme inhibitors and angiotensin receptor blockers
• should be avoided in pregnant women and in the preconception period
associated with neonatal renal failure, oligohydramnios, and death
For the same reasons, they should not be considered first-line
treatment for hypertension in women of childbearing age in general.
11/26/2023 DAJANE N.(BSc, MSc) 73
Medical history…
Hypertension
The following have good safety profiles and are effective for treatment.
• Short-acting β-blockers- labetalol
• calcium channel blockers- nifedipine, and
• Α-blockers-methyldopa
Diuretics do not have a teratogenic effect but are not first-
line treatment for hypertension
• exacerbate the intravascular volume depletion that accompanies preeclampsia.
11/26/2023 DAJANE N.(BSc, MSc) 74
Medical history…
Heart disease
• Pre-pregnancy counselling
The risk of pregnancy depends on the specific heart disease
clinical status of the patient.
Individual counselling by experts is recommended
• Adolescents
advice on contraception,
pregnancy issues should be discussed as soon as they become
sexually active
• High risk patients should be managed by an expert multidisciplinary team

Epilepsy
• The risk of fetal abnormality increases with the number of different
anticonvulsant medications being taken and women considering pregnancy
should, therefore, have the number minimized.
11/26/2023 DAJANE N.(BSc, MSc) 85
Medical hx…
Epilepsy
• All epileptics on medication should also be given 5 mg folic acid daily from
3 months preconception
to counteract the folate-antagonist effect of the drugs thus reduce the
chance of a neural tube defect in the fetus.
11/26/2023 DAJANE N.(BSc, MSc) 86
Medical hx…
• Many major antiepileptic drugs
• e.g. valproate [Depacon], phenytoin [Dilantin], carbamazepine (Tegretol),
phenobarbital) are teratogenic
• Rates of congenital anomalies are related to higher doses and polytherapy
• Monotherapy should be used when possible at the lowest effective dosage

Medical: Hyperthyroidism
Women with overt hyperthyroidism, should be counseled prior to pregnancy re
garding treatment options (medications, radioactive iodine ablation, or
subtotal thyroidectomy)
Goal of treatment: maintain serum free thyroxine (T4
) levels in the high normal to slightly above normal range.
• Free T4 levels: measured every 2–4 weeks and doses adjusted accordingly.
11/26/2023 DAJANE N.(BSc, MSc) 95
Medical: Hyperthyroidism
Achieving eu-thyroidism before pregnancy
Propylthiouracil is preferred in preconception and first trimester;
methimazole (Tapazole) is preferred in the second and third trimesters
Possible teratogenicity in the first trimester with methimazole and liver
failure with PTU after first trimester
11/26/2023 DAJANE N.(BSc, MSc) 96
ASTHMA
• Is a prevalent chronic condition, affecting approximately 4% to
9% of all pregnancies(USA)
one third of women with asthma maintain control similar
one third worsen, and
one third improve
• Maternal and fetal complications are associated with poorly
controlled maternal asthma
preterm birth
low birth weight (LBW)
increased perinatal mortality, and
maternal preeclampsia
11/26/2023 DAJANE N.(BSc, MSc) 97
Asthma…
• inadequate control of asthma is a greater risk to the fetus than asthma
medications are
• Ideally, asthma control should be optimized prior to conception
• poor asthma control prepregnancy
increased risk of intrauterine growth retardation and
hypertension during pregnancy
11/26/2023 DAJANE N.(BSc, MSc) 98
Asthma…
During pregnancy:
One third of women experience improvement in symptoms
One third experience a worsening of symptoms, and
One third remain unchanged
11/26/2023 DAJANE N.(BSc, MSc) 99
Asthma…
• If left uncontrolled, can be associated with:
premature birth
Preeclampsia
low birth weight and growth restriction,
increased need for cesarean section, and
increased maternal morbidity and mortality.
11/26/2023 DAJANE N.(BSc, MSc) 100
Asthma…
• The goals for symptom control in pregnancy are the same as in the nonpregnant
state: use of rescue inhalers less than twice a week, nighttime
awakenings less than twice per month, and lack of activity impairment due to sy
mptoms.
• A stepwise approach to treatment is recommended
use the lowest amount of drug necessary to control symptoms, but it is safer for pregnant
women to be treated for asthma than to experience exacerbations and hypoxia.
11/26/2023 DAJANE N.(BSc, MSc) 101
Asthma…
Management
• Inhaled Corticosteroids
• The 2018 Global Institute for Asthma have suggested that all ICS products are
safe during pregnancy.
• Women with well controlled asthma should be continued on their
current ICS regimen to avoid the potential for a break in therapy and
loss of asthma control related to a drug change.
11/26/2023 DAJANE N.(BSc, MSc) 102
Thrombophilias
Assess the need for thromboprophylaxis during pregnancy: ACOG-
recommended management guidelines.
oLow risk for thrombophilia if testing is positive for any of the following:
heterozygous factor V Leiden mutations, heterozygous prothrombin
G20210A mutations, protein C deficiency, protein S deficiency
oHigh risk for thrombophilia if testing is positive for any of the following:
homozygous factor V Leiden mutations, homozygous prothrombin
G20210A mutations, heterozygosity for both factor V Leiden and
prothrombin G20210A mutations, antithrombin deficiency
11/26/2023 DAJANE N.(BSc, MSc) 103
Thrombophilias
• Consider initiating low molecular weight heparin (LMWH) or
unfractionated heparin (UFH) if indicated
• Except in cases of mechanical heart valves, warfarin is
contraindicated in pregnancy
• Monitor patients for thromboembolic events due to increased risk
during pregnancy
11/26/2023 DAJANE N.(BSc, MSc) 104
Reproductive history
• Prior preterm birth infant
evaluation of remediable causes is recommended for a next pregnancy
• Prior cesarean delivery
advise women to wait at least 18 months for a subsequent pregnancy.
• Prior miscarriage
• Prior stillbirth
• Uterine anomalies
11/26/2023 DAJANE N.(BSc, MSc) 105
Vaccination(Immunization)
Evaluation of a woman’s immune status should occur in the
preconception period.
Optimally, immunization with indicated vaccines should occur prior to
pregnancy.
For the reproductive age female, preconception evaluation of
immunity to rubella, varicella, and hepatitis B are particularly
beneficial for the health of the woman and her offspring
11/26/2023 DAJANE N.(BSc, MSc) 106
Vaccination(Immunization
• Maternal vaccination
Provides protection of the neonate through passive immunization
Maternal antibodies (IgG) are transmitted transplacentally, particularly in
the last 4–6 weeks of gestation.
An additional benefit may occur with the passage of antibodies (IgA) via
breast milk.
In addition, by immunizing close contacts of a newborn, the risk of
exposure to disease is reduced, a strategy known as cocooning.
11/26/2023 DAJANE N.(BSc, MSc) 107
Vaccination/Immunizations
includes assessment of immunity against common pathogens
depending on health status, travel plans, and time of year
Vaccines that contain toxoids such as tetanus are suitable before or
during gestation
11/26/2023 DAJANE N.(BSc, MSc) 108
Vaccination/Immunization…
Vaccine containing killed bacteria or viruses(Inactivated vaccine)
are not associated with adverse fetal outcomes
are not contraindicated preconceptionally or during pregnancy
• E.g. influenza, pneumococcus, hepatitis B, meningococcus, and
rabies vaccines
11/26/2023 DAJANE N.(BSc, MSc) 109
Vaccination/Immunization…
Live, attenuated vaccines:
are contraindicated in pregnancy
If live, attenuated vaccines are administered, the patient should avoid pregnancy for
4 weeks because of the theoretical concern for transplacental infection of the fetus
E.g.varicella-zoster, measles, mumps, rubella, polio, chickenpox, and yellow fever
• 1 month or longer pass-between vaccination and conception attempts
• immunize the susceptible patient against influenza and tetanus, diphtheria and
pertussis
11/26/2023 DAJANE N.(BSc, MSc) 110
Vaccination/Immunization…
Typhoid immunization is recommended on travel to an endemic region.
Cholera immunization should be given only to meet travel requirements.
Tetanus-diphtheria immunization should be given if a primary series has
never been administered or if 10 years has elapsed without the patient
receiving a booster.
Immunization for yellow fever is recommended before travel to a high
risk area.
11/26/2023 DAJANE N.(BSc, MSc) 111

• Hepatitis B: Ensures protection against hepatitis B virus.
• Rubella (German Measles): Prevents rubella infection, which can be harmful during
pregnancy.
• Varicella (Chickenpox): Protects against chickenpox.
• Tdap (Tetanus, Diphtheria, and Pertussis): Ensures immunity against these diseases.
• Influenza (Flu): Annual flu vaccination is advisable.
11/26/2023 DAJANE N.(BSc, MSc) 141
PCC for men…
• Sperm Health and Fertility:
• Keeping testicles cool is crucial for healthy sperm production. Men can:
• Wear loose-fitting underwear (such as boxer shorts) to maintain
optimal testicular temperature.
• Avoid prolonged sitting to prevent heat buildup.
• Lifestyle factors like quitting smoking, reducing alcohol intake, and
avoiding recreational drugs positively impact fertility.
11/26/2023 DAJANE N.(BSc, MSc) 142
PCC for men…
• General Health Check-up:
• Men should have a general medical check-up before attempting to
conceive.
• Discuss any existing medical conditions with a healthcare provider.
• Address any health issues that may affect fertility.
• Sexually Transmitted Infections (STIs):
• Men should be screened for STIs, as they can lead to infertility.
• Testing before conception reduces the risk of passing infections to a
partner.

U.S. Food and Drug Administration Pregnancy Risk
Categories for Medications
11/26/2023 DAJANE N.(BSc, MSc) 145
Category Definition
A Controlled studies in pregnant women fail to demonstrate a risk
to the fetus in the first trimester, there is no evidence of risk in
later trimesters, and the possibility of fetal harm appears remote.
Medications in this class are considered safe to use in pregnancy
B Either animal-reproduction studies have not demonstrated a fetal
risk but there are no controlled studies in pregnant women, or
animal-reproduction studies have shown an adverse effect (other
than a decrease in fertility) that was not confirmed in controlled
studies in women in the first trimester (and there is no evidence
of a risk in later trimester
Medications in this class are generally considered safe.
C Either studies in animals have revealed adverse effects on the
fetus (teratogenic or embryocidal or other) and there are no
controlled studies in women, or studies in women and animals
are not available. Drugs should be given only if the potential
11/26/2023
benefit justifies the potential risk to the fetus.
DAJANE N.(BSc, MSc) 146
Category Definition
D There is positive evidence of human fetal risk, but the
benefits from use in pregnant women may be acceptable
despite the risk (e.g., if the drug is needed in a life-
threatening situation or for a serious disease for which safer
drugs cannot be used or are ineffect
X Studies in animals or humans have demonstrated fetal
abnormalities or there is evidence of fetal risk based on
human experience, or both, and the risk of the use of the
drug in pregnant women clearly outweighs any possible
benefit. The drug is contraindicated in women who are or
may become pregnant.
