Association of geographic and seasonal variation with diverticulitis admissions.

ABSTRACT:

Importance

The incidence of diverticulitis has been associated with geographic and seasonal variation. Low levels of circulating vitamin D are associated with diverticulitis. We investigated the association between UV light and diverticulitis.

Observations

We identified nonelective diverticulitis admissions in the Nationwide Inpatient Sample and linked hospital locations to UV data. We examined UV exposure in relation to risk of admission for diverticulitis. We identified geographic and seasonal trends among 226 522 nonelective admissions for diverticulitis. Compared with high-UV areas, low-UV areas had a higher rate of diverticulitis (751.8 vs 668.1 per 100 000 admissions; P < .001), diverticular abscess (12.0% vs 9.7%; P < .001), and colectomy (13.5% vs 11.5%; P < .001).
