Possible answers

The median BMI is roughly 25 for all general health categories, and there is a slight increase in median BMI as general health status declines (from excellent to poor).

The IQR increases slightly as general health status declines (from excellent to poor).

Among people with excellent health, there are some with unusually low BMIs compared to the rest of the group.

The distributions of BMIs within each health status group is left skewed.
