Throughout the world the prevalence was higher in males than females, resulting in an average male:female sex ratio of 1.8 (Degenhard et al, 2013). Prevalence peaks worldwide in the 20-24 years age group at between and then steadily decreasing after that age group thereafter (Degenhard et al, 2013). | Throughout the world the prevalence was higher in males than females, resulting in an average male:female sex ratio of 1.8 (Degenhard et al, 2013).

Prevalence in high income regions was much higher than that in low to middle income regions and the global average (Degenhard et al, 2013).
