Background: Health effects of air pollution on anaemia have been scarcely studied worldwide. We aimed to explore the associations long-term exposure ambient pollutants with prevalence and haemoglobin levels in Chinese older adults. Methods: used two-level linear regression models modified Poisson robust error variance examine particulate matter (PM) nitrogen dioxide (NO2) concentrations anaemia, respectively, among 10,611 adults enrolled World Organization (WHO) Study global AGEing adult health (SAGE) China. The average community (PM an aerodynamic diameter 10 μm or less (PM10), 2.5 (PM2.5), 1 (PM1) (NO2)) for each participant was estimated using a satellite-based spatial statistical model. Haemoglobin were measured participants from dried blood spots. controlled confounders. Results: All significantly associated increased single pollutant model (e.g., ratios increase inter quartile range three years moving PM10 (1.05; 95% CI: 1.02–1.09), PM2.5 (1.11; 1.06–1.16), PM1 (1.13; 1.06–1.20) NO2 (1.42; 1.34–1.49), respectively. These also lower haemoglobin: (−0.53; −0.67, −0.38); (−0.52; −0.71, −0.33); (−0.55; −0.69, −0.41); (−1.71; −1.85, −1.57) Conclusions: Air decreased cohort
