The incidence, prevalence, and mortality reported for chronic pancreatitis vary as a result of differences in study design, diagnostic criteria, and geography. The age at presentation varies with aetiology. The peak age at presentation for hereditary pancreatitis is 10-14 years, for juvenile idiopathic chronic pancreatitis is 19-23 years, for alcoholic chronic pancreatitis is 36-44 years, and for senile idiopathic chronic pancreatitis is 56-62 years.[10]Mullhaupt B, Truninger K, Ammann R. Impact of etiology on the painful early stage of chronic pancreatitis: a long-term prospective study. Z Gastroenterol. 2005 Dec;43(12):1293-301.

The global pooled incidence of chronic pancreatitis is 9.62 cases (95% CI 7.86 to 11.78) per 100,000 person-years, and mortality is 0.09 deaths (95% CI 0.02 to 0.47) per 100,000 person-years.[13]Xiao AY, Tan ML, Wu LM, et al.
