Does acne discourage exercise?

A study conducted at the UK's Bath University concluded that people who have a problem with acne are less likely to excel in sports or other physical activities. It's not because of any lack of ability, it's strictly because acne can affect someone's self esteem to a point that they will avoid signing up for sports. The study followed 50 adults who were part of an acne support group.

I wasn't at all surprised to read this. In my opinion it's not a result of the acne necessarily, but a result of the reduced self esteem. (Which, for those included in the study, was largely a result of their acne.) Other triggers for self esteem issues -- obesity, etc -- can also be cited as the reason for not joining sports or working out. Whatever the impetus, it's unfortunate that anyone sidelines themselves because of social anxiety.

How about you? Have you ever had a problem that made you nervous about joining a sport?
