What are national physical activity recommendations?
• They are epidemiological thresholds where optimal behaviour is associated with a significantly reduced risk of disease

Method
• Google images search: terms used:– Pregnancy
– Exercise
– Infographics
• Excluded: – Those with Predominantly Nutritional content, not
relevant to exercise and pregnancy
– Those that just contained pure pictures Exercises
– Those just contained pelvic floor exercise

Key messages of qualitative papers
POVs of pregnant women
• PW say their HPs don’t mention about
• PW respect HPs and would like advice
• Lack of advice lead PW to seek alternatives of information
POVs of Health Professionals
• Advice is vague and non specific
• HPs happy to recommend type of physical activity with no specifics for FIT
• Undertrained
• Unsure what to say, and they do mention it

Conclusions
• Yes a need for guidance for HPs and patients• Information must be positive and clear about benefits and
risks of physical activity and pregnancy• Specific guidance should include
– Frequency– Intensity– Time– Type of physical activity – must be appropriate for stage of
pregnancy and current physical activity status– Reduction of sedentary behaviour – Pelvic floor exercises?
• What else matters?
