chapter 54 Pregnancy and antenatal care
PRECONCEPTION COUNSELLING
Chronic medical conditions such as diabetes need to be fully assessed and management optimised.
An important principle to remember is that any investment in the mother’s wellbeing—and the wider family, for that matter—is an investment in the wellbeing of the pregnancy and the future of the child. Preparation for pregnancy needs to address the woman’s physical, emotional and spiritual situation, including her beliefs about her relationship, parenting and lifestyle. It is helpful to consider the elements using the ESSENCE model, as discussed below (also see Ch 6).
EDUCATION
Planning a pregnancy is the time when women are arguably the most interested they have ever been in optimising their health, in the interests of having a healthy baby. It is also an opportunity to discuss the potential father’s lifestyle and general health. The advice provided at the preconception consultation may be the last chance to see the patient before she becomes pregnant, so this consultation needs to address issues that will be important in the early stages of pregnancy, even before she knows she is pregnant.
STRESS MANAGEMENT
Because the mother’s stress hormones (including cortisol and catechols) cross the placenta, maternal stress also affects fetal neurological, physiological and metabolic development. For example, significant and prolonged maternal stress,1,2 particularly in the first trimester, is associated with poorer fetal growth, developmental problems, an increased risk of mental illness and a higher risk of cardiovascular disease in the offspring.
SPIRITUALITY
Starting a family affects a woman, her family and her work in profound ways. Asking about what all this means for her and how she will adjust may be an important conversation. A preliminary discussion of a patient’s religious or spiritual beliefs may be appropriate, particularly if there is a problem with fertility, if the pregnancy fails to proceed or if antenatal testing reveals a fetal abnormality.3 A discussion of the parents’ religious views about circumcision, should they have a male child, may be appropriate in the planning stages.
EXERCISE
Once the patient is pregnant, she can continue or adjust her current exercise program (Box 54.1).

NUTRITION
However, women who are either significantly overweight or underweight need to address this risk factor. Obese women are 2.7 times more likely to be infertile than women in the healthy weight range. Obesity in women can also increase the risk of miscarriage and impair the outcomes of assisted reproductive technologies and pregnancy.4 It is also associated with an increased rate of caesarean section.5
Being underweight is associated with reduced conception rates among nulliparous women and increased likelihood of conception among parous women.6
Some foods are to be avoided because of the risk of listeriosis, which causes a risk of miscarriage. These foods include raw seafood, pre-prepared (salad bar) salads, delicatessen meats, leftovers, soft cheeses and pâté. All fruit and vegetables should be washed in filtered water before eating.
ANTENATAL CARE
Women suitable for shared antenatal care with their general practitioner (GP) include those defined as healthy women having a normal pregnancy. Complications usually requiring additional care by an obstetrician or other specialist are summarised in Box 54.2. Some of these women may still be suitable for shared care, with some modification of the usual schedule of visits.
