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.

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.

Cardiac….

• multi-disciplinary cardio-obstetrics team


to facilitate shared decision making with the patient at every stage of
the process.

• Risk categories range from I to IV

A) Class I: being isolated atrial or ventricular ectopic complexes which do not


portend an increased risk

B) Class IV: significant pulmonary hypertension from any cause

11/26/2023 DAJANE N.(BSc, MSc) 81


Cardiac….
• Prohibitive conditions: include

severe left ventricular dysfunction

severe left-sided heart obstruction

significant aortic aneurysms associated with bicuspid aortic valve and

Marfan syndrome

• Most women with these high risk conditions are recommended to avoid pregnancy,

contraceptive planning is also advised in these high risk patients.

• Review all cardiovascular medications for contraindications

E.g. teratogenic angiotensin converting enzyme inhibitors that will require alternatives.

Medical hx…

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

11/26/2023 DAJANE N.(BSc, MSc) 87


Medical hx…

Epilepsy

• Treatment goals:

to achieve seizure control with monotherapy and with medications

considered less teratogenic

11/26/2023 DAJANE N.(BSc, MSc) 88


Epilepsy…

• Anti-seizure medication discontinuation before pregnancy in suitable


candidates
a. have been seizure-free for 2 to 5 years
b. display a single seizure type

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

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.

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

 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

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.
