Regional variations in serum pepsinogen levels and their influencing factors: a multi-center cross-sectional study.

ABSTRACT: Serum pepsinogen (PG) levels are recognized biomarkers influenced by various factors, including lifestyle, Helicobacter pylori (H. pylori) infection status, and the presence of gastric mucosal lesions. However, whether baseline serum PG levels exhibit regional heterogeneity independent of concurrent gastric mucosal lesions has not been clearly established. The study aims to investigate the variability of baseline serum PG levels and identify potential influencing factors across China. Data were collected from individuals undergoing routine health checkups at twelve collaborating medical centers across China between October 2016 and October 2021. Serum pepsinogen I (PGI) and pepsinogen II (PGII) were measured and the pepsinogen I/II ratio (PGR) was calculated; gastroscopy with histopatholog
