Quite possibly.
I can imagine that knowing you run the risk of falling/getting hurt due to a medical condition whilst out will tend to put you off going out, or things like sight problems that mean you can't see dangers or even people easily let alone signage etc.
It doesn't help these days that many places won't have anywhere someone who needs to be able to stop/rest can, be they disabled or elderly, most towns and shopping centres for example seem to have got rid of most or all of the old benches*, and in some places where they still have "rest areas" they're those horrific no support sloped things that basically just give you something to lean on.
Despite supposedly disabled access being more important today than it used to be, a lot of places that have been refurbished/updated seem to have had choices made that actively make them worse for some of the most common mobility issues, especially the likes of train stations.
*In an attempt to force the homeless out of sight usually, it's amazing the IRA didn't manage to get councils to get rid of benches, as a smart designer came up with the mesh ones you couldn't hide something under, but the wish to force the homeless out of view did.
