Answer

In a series of pneumomediastinum occurring in persons with asthma, there was a very slight male predominance in the prevalence of spontaneous pneumomediastinum. Other series confirm this excess of male cases. Damore reported 29 cases of pneumomediastinum over a 10-year period unrelated to trauma, intubation, or surgical procedures; 69% of patients were male. [13] Some have suggested that a body habitus favoring a tall thin build is an additional risk factor for the development of spontaneous pneumomediastinum. The mechanisms underlying this association are unclear. Traumatic pneumomediastinum is more common in males, reflecting the male predominance among those who experience trauma and accidents.
