Despite the well-known health benefits of physical activity, physical inactivity remains highly prevalent globally. Effective population strategies to promote physical activity are needed to reduce the global burden of non-communicable diseases stemming from physical inactivity. But the question is: how do we effectively promote physical activity at the population level, such as in entire communities?

Our study, recently published in the IJE, looks at the relationship between pre-gestational weight status and children’s neurodevelopment. It shows that children born to mothers who were normal weight before pregnancy scored better on cognition tests than children born to obese women. An original aspect of our study is that it summarises the evidence provided by 15 previous follow-up studies, including samples from seven different countries, and provides information for both cognition tests and general intelligence scores.

We don’t yet know whether it’s best to do it all at once, or little and often, but what we do know is that if a woman’s day-to-day activity contains 1–2 minutes of weight-bearing, high-intensity activity, similar to a medium-paced run for pre-menopausal women or a slow jog for post-menopausal women, she will have better bone health than women who do less. The benefits of high-impact activity on bone health are nothing new. What is novel about our findings is that better bone health is linked to such a short amount of daily activity, albeit at an intensity of the running variety.
