Thinking of my own experience with family, my guess is that a bone breaking is a symptom and not a cause here for this statistic. People lose their balance and get confused with Alzheimer’s and the like and my uninformed guess is that the breaking bone highlights that someone is on the way out anyway, and isn’t the reason for it.

People break their bones faster when they are older due to calcium deficiency. So that's a symptom but not of what you are thinking.
