Children with disabilities are left behind where schools promote physical activity: intervention-generated inequalities in a national survey of Chilean children and adolescents
A national survey of Chilean children reveals that school-based physical activity promotion measures inadvertently widen the gap between children with and without disabilities, as these initiatives primarily benefit non-disabled peers while leaving children with disabilities more inactive and sedentary.

In the world of public health, there is a persistent hope that providing resources to everyone will lift the whole community. The idea is that if schools offer better sports facilities, more coaching, and health talks, every child will benefit equally. This approach assumes that these programs are neutral tools, like a new playground that any child can use. However, researchers have long worried about a different possibility: that well-meaning programs might actually widen the gap between the most advantaged and the most vulnerable. This happens when a program works well for those who are already able to participate, but fails to reach those who face extra barriers, leaving them further behind than before. This phenomenon, known as intervention-generated inequality, suggests that simply adding more opportunities does not guarantee fairness. The question becomes whether the very places designed to help children move more are inadvertently helping some while leaving others behind.
A recent study in Chile investigated this exact question by looking at how school-based physical activity programs affect children with disabilities compared to their peers. The researchers analyzed data from over 4,000 children and teenagers, examining whether the presence of school sports facilities, workshops, and health talks changed the activity levels of children with disabilities. They found a surprising and troubling pattern. In schools that had no special promotion measures for physical activity, children with disabilities were just as active as children without disabilities. There was no gap in their participation in organized sports, nor in how much time they spent being inactive. The situation changed dramatically, however, in schools that did have these promotion measures.
In schools with these programs, the gap appeared and grew. Children with disabilities were significantly less likely to join organized sports teams or clubs than their peers. While children without disabilities saw their activity levels rise in these environments, children with disabilities did not experience the same boost. In fact, in schools with the most promotion measures, children with disabilities were much more likely to be inactive and to spend long hours sitting still. The study showed that for every additional measure a school added, the gap between the two groups widened. This was not a case of children with disabilities lacking access to the schools; in fact, they were more likely to attend schools that had these facilities and programs. The issue was not that the resources were missing, but that the resources were not working for them.
The researchers discovered that this inequality was not present in younger children but became very clear in teenagers. Among children aged five to eleven, the programs did not create a gap. But for those aged twelve to seventeen, the difference was stark. In schools with promotion measures, teenagers with disabilities were half as likely to participate in organized sports as their peers, and they were more than twice as likely to be inactive. The programs seemed to help the teenagers who were already able to engage, while the teenagers with disabilities fell further behind. The study also found that the gap was most pronounced in activities that happened outside of school, such as joining local sports clubs, rather than in the school workshops themselves. This suggests that the environment created by these schools encourages participation for some, but fails to create a pathway for others to follow.
The findings challenge the assumption that universal programs are automatically inclusive. The data indicates that when schools add more sports workshops, gyms, and health talks, the benefits flow disproportionately to children without disabilities. The children with disabilities, who are already at a disadvantage, do not see the same improvement. Instead, they end up spending more time sitting and less time moving compared to their peers in the same schools. The researchers emphasize that this is not because the schools are excluding these children, but because the design of the programs does not account for their specific needs. The study concludes that simply counting how many schools have a gym or a sports program is not enough to measure success. To truly understand if these programs are working, officials need to look at whether the gap between children with and without disabilities is closing or widening. Without specific designs that ensure inclusion, these well-intentioned efforts may be doing more harm than good by leaving the most vulnerable children behind.
