Risk factors of acute pancreatitis in young adults: a Nationwide population-based cohort study in South Korea.

ABSTRACT

OBJECTIVES: This study aimed to identify the risk factors for acute pancreatitis (AP) in young adults in their 20s based on data from the nationwide cohort in South Korea. METHODS: From the 2009 national health examination database of South Korea, total 471,098 individuals between the ages of 20 and 29 were analyzed. To identify the newly developed AP, the linked claims database was used. RESULTS: The incidence rates of AP were 18.8 and 9.8 per 100,000 person-years in male and female participants, respectively. Alcohol consumption and smoking were associated with the heightened risk of AP. The risk of AP development was increased as daily alcohol consumption increased. Also, ex-smokers and current smokers showed higher AP risk than never smokers. Hypertriglyceridemia and obesity were associated with the increased AP risk as well. Compared to female participants, male participants showed a higher risk of AP in univariate analysis, but showed a lower risk of AP in multivariate analysis. CONCLUSIONS: In the young adult population, alcohol consumption, smoking, hypertriglyceridemia, and obesity were associated with an elevated risk of developing AP. It is important to identify and manage the modifiable AP risk factors in young adults to minimize the socioeconomic burden of AP.
