Epidemiology
In tennis players, about 39.7% have reported current or previous problems with their elbow. Less than one quarter (24%) of these athletes under the age of 50 reported that the tennis elbow symptoms were "severe" and "disabling." While 42% over 50 identified severe and disabling symptoms. More women (36%) than men (24%) considered their symptoms to be severe and disabling. Tennis elbow is more prevalent in individuals over 40, where there is about a 4-fold increase among men and 2-fold increase among women. Tennis elbow equally affects both sexes and although men have a marginally higher overall prevalence rate as compared women, this is not consistent within each age group, nor is it a statistically significant difference.
Playing time is one factor in tennis elbow occurrences. However, an increased incidence with increased playing time is statistically significant for only respondents under the age of 40. Individuals over the age of 40 who played over 2 hours, had a 2-fold increase in chance of injury. Those under 40 had a 3.5 times increase compared to those who played less than 2 hours per day.
