We do know that it changes over time. Although younger girls under five tend to be less active than boys, it's as they get older that we see a decline in physical activity. There's still a lot more to be done, but we do know that at a certain point, some girls may choose to not be as active in some of the more traditional physical activities, such as organized sport in a school setting. It may be gender biases influencing what's appropriate for girls to be doing or not doing, and similarly for boys to be doing or not doing. We've seen some of that carry over in the sporting community—in hockey, you see a lot higher participation rates for girls, but there are other areas where we tend not to see those same levels of activity.
I would say it's an area of strong interest. I do know that some of our colleagues in the research community are looking at this issue more closely. Within our own funded projects, such as FitSpirit, we're trying to better unpack this issue. We're also trying to unpack this for a range of young people who may be along a gender continuum that is not just about being a boy or a girl and self-identify as LGBTQ, as an example. We need to be making sure that our programs are inclusive.
