In this article, we will look at antenatal care, its purpose, and what can or cannot be achieved by mothers receiving it.

What is antenatal care?

The care a pregnant woman receives from a healthcare professional over the course of her pregnancy is referred to as antenatal care (ANC). It is used to detect early signs of complications, followed by a timely intervention if any are found. This care also focuses on educating the pregnant woman on a range of topics, including well-being, birth preparedness, complication readiness, and breastfeeding.

History of antenatal care

ANC has been recommended by the Ministry of Health in the UK since 1929. The recommendation for care is as follows:

  • One visit from as early in pregnancy as possible (before or after 16 weeks)
  • A second visit at 24 and 28 weeks
  • From 28 weeks. fortnightly visits until 36 weeks
  • From 36 weeks, weekly visits until the onset of labour.

During these visits, the healthcare professional measures uterine height checks the foetal heartbeat tests urine and measures the mother’s blood pressure. This same structure of ANC has been adopted worldwide. The WHO recommends a minimum of eight visits to prevent perinatal mortality and ensure women’s satisfaction with care, in order to lead to the:

  • early identification and treatment of already established disease
  • Early detection of complications and other potential problems that can affect the outcomes of pregnancy
  • Prophylaxis and treatment for anaemia, malaria, tetanus, and sexually transmitted infections including HIV and urinary tract infections. Prophylaxis refers to an intervention aimed at preventing a disease or disorder from occurring.
  • Individualised care and advice to help maintain normal progress and preparedness for delivery. WHO also recommends providing social, cultural, emotional, and psychological support to pregnant women in a respectful way to improve lives, health-care utilisation and quality of care.

Who receives care?

Globally, while 85% of pregnant women receive ANC at least once, only 58% receive at least four antenatal visits. In regions with the highest maternal mortality rates, such as sub-Saharan Africa and South Asia, even fewer women receive at least four antenatal visits (49% and 42%, respectively) 1.

In the UK, pregnant women receive on average 9-10 ANC visits depending on whether or not they have had a previous pregnancy 2.

Does antenatal care reduce maternal mortality?

ANC is thought to prevent high-risk complications in pregnancy, but evidence for this is lacking for many outcomes. It is unlikely to impact on some major causes of maternal mortality, such as haemorrhage and obstructed labour.

These types of emergencies are prevented through prompt recognition and emergency care, which antenatal care does not provide. It does, however, aim to educate the woman on recognising signs of these types of complications, which can help to save their lives and promote birth preparedness.

ANC also provides effective interventions for preventing and treating certain conditions, such as anaemia, pre-eclampsia and eclampsia, the external cephalic version to detect a breached position, and infections, some of which impact the health of the newborn as well as the mother, e.g. malaria, HIV, tetanus, syphilis, gonorrhoea, bacteriuria.

Dowswell, et al. state that “It is reasonable to assume that antenatal care does confer some health benefits, although how it does so may be complex and multi-factorial 3.”
