Worldwide Seasonal Variation in Hospital Admissions for Diverticulitis

Key Points

To investigate the seasonal patterns of hospital admissions for diverticulitis globally.
Conducted a systematic review of existing studies on diverticulitis admissions.
Analyzed seasonal trends in hospital admissions across different global regions.
Compared data between northern and southern hemispheres to observe phase reversal.
Diverticulitis admissions peak during warmer months consistently.
Identified a reproducible seasonal pattern across various regions.
Found a consistent phase reversal of peak admissions between northern and southern hemispheres.

Abstract

This systematic review found that diverticulitis exhibits a reproducible seasonal pattern, more commonly peaking in warmer months and with consistent phase reversal between hemispheres. The findings suggest environmental or behavioral triggers rather than random variation. Future prospective studies integrating patient-level exposures are needed to clarify mechanisms and identify preventive strategies.
