As being pregnant affects a woman's physical activity beliefs and behaviours, focusing on this can be a useful way to introduce the topic


Ask permission

Ask permission to talk about either ‘physical activity’ or ‘something that can make a big difference to your future health and wellbeing’.

Spending a moment to set the scene and asking permission can open a constructive person-centred conversation around behaviour change. This keeps the individual actively engaged in the conversation and decision making.


Assess impact

How has their pregnancy affected their physical activity levels and the things they enjoy?

Supporting behaviour change is hard work! This resource is designed to help you navigate this challenging task.

Most people are ambivalent about, rather than resistant to, increasing their physical activity levels. There are pros and cons to both maintaining the same physical activity levels as well as increasing them. Your challenge is to help an individual to consider and share their own ‘pros’ for increasing their physical activity levels and help them to develop these ideas into a workable plan that fits into their life.

Try to understand the individuals own perspective, agenda and priorities and do not assume they: (1)

  1. ought to change
  2. want to change
  3. are primarily motivated by their health
  4. either ARE or ARE NOT motivated to increase their activity levels
  5. will respond well to a tough approach from you
  6. must (or will) follow your advice

Learning skills such as motivational interviewing can help you avoid common pitfalls that sometimes make conversations about behaviour change unrewarding and ineffective.

Review activity

Physical activity calculator

The physical activity ‘vital sign’ is a simple way of assessing an individual’s physical activity level. It has been validated in a cohort of 1.73 million people in the USA against self report survey data[1,2] and is in use worldwide[3]. It serves as a screening tool for clinical staff to inform brief consultations in physical activity as per NICE recommendations[4]. As this tool does not assess strength and balance these should be asked about separately.

Explore benefits

What do they know about some of the benefits of physical activity in pregnant women?

As an individual is more likely to change if they can personally identify with the ‘pros’ for change, help them to identify how they might benefit from being more active. Find out what they know first so that you can add to their existing understanding by sharing some of the wide-ranging benefits of being more active.

Q1 On average, how many days each week do you do moderate or greater physical activity (like a brisk walk) ?


Q2 On those days, on average how many minutes do you do this physical activity for?


Inactive. Only small increases in physical activity across the week can have large health benefits.

Insufficiently active. A good start, but there is still a lot to be gained by increasing physical activity levels.

Active. Well done. Maintaining this level of activity is really important.

Explain that just 30 minutes physical activity in one week can make a huge difference to their health.

Lower: 0.77
Relative Risk
Higher: 1
Minutes Per Week

Did you know?

The least active individuals stand to gain the most from a small increase in physical activity.

Large health gains are seen in individuals increasing their activity levels from very low amounts. For instance, increasing from 10 to 20 minutes of moderate intensity activity per week has a significant effect on life expectancy even though individuals are below the recommended 150 minutes of moderate intensity. So, it’s worth supporting very inactive individuals to change their behaviour, particularly as many of the least active members of the population are often seen in healthcare settings.
