Associations between body mass index and gastroesophageal cancer incidence and mortality: novel insights from a nationwide registry-based cohort study.

ABSTRACT: The association between body mass index (BMI) and cancers of the esophagus and the stomach remains complex and requires further exploration. This study aimed to investigate this association, including early-onset (< 50 years) cancer and cancer related mortality. A nationwide registry-based cohort study was performed by linking data from multiple national registries in Norway. The cohort included 1,723,692 individuals, with 22,473 gastroesophageal cancer cases identified over 55,701,169 person-years of follow-up. In men, a 5 kg/m2 increase in BMI was associated with an increased risk of esophageal (HR 1.34, 95%CI 1.22-1.48) and cardia adenocarcinoma (HR 1.36, 95% CI, 1.22-1.50). This finding extended to individuals with high BMI in early life (16-29 years) for esophageal adenocarcinoma. The
