Differential gastrointestinal mortality in Native Hawaiian/Pacific Islander and Asian subgroups in the U.S.: a cross-sectional analysis of national mortality surveillance data 2018–2023

Year: 2026

Abstract: Background: Asians and Native Hawaiians/Pacific Islanders (NHPIs) comprise 8% of the U.S. population with over 40 subgroups. Health data often aggregate these subpopulations, limiting group-specific estimates. In 2018, modifications to death certificates allowed for the disaggregation of NHPIs from Asians. This study examines differences in gastrointestinal-related mortality between NHPI and Asian adults across all major gastrointestinal disease categories. Methods: We analyzed mortality data for adults aged ≥25 years from the National Center for Health Statistics 2018-2023. Established definitions classified NHPI and Asian individuals based on single or multi-race listings. Gastrointestinal-related deaths were identified using validated ICD-10 codes and categorized into liver diseases, colorectal cancer, upper gastrointestinal cancers, and non-cancer digestive diseases. Age-standardized mortality rates (ASMRs) per 100,000 and rate ratios were calculated. Findings: Between 2018 and 2023, there were 3322 gastrointestinal-related deaths among NHPI adults (mean age 63.9 years, standard deviation 14.4; 1373 [41.3%] female decedents) and 47,275 among Asian adults (mean age 70.2 years, standard deviation 14.6; 20,892 [44.2%] female decedents). Overall gastrointestinal-related ASMR for NHPIs was 66.8 (95% CI: 64.5-69.2) per 100,000 adults. NHPIs exhibited higher mortality rates than Asians in all gastrointestinal disease categories. NHPIs had 24% higher overall gastrointestinal-related mortality rate than Asians (RR: 1.24; 95% CI: 1.20-1.29), with 33% higher for liver diseases (RR: 1.33; 95% CI: 1.24-1.44) and 63% higher for non-cancer digestive diseases (RR: 1.63; 95% CI: 1.49-1.77). Interpretation: NHPIs (vs. Asians) have higher gastrointestinal-related mortality rates, with the greatest disparities observed in liver diseases and non-cancer digestive diseases. By disaggregating data across the full spectrum of gastrointestinal diseases, this study provides a clearer understanding of NHPI-specific disparities and highlights critical areas for targeted public health efforts.
