A systematic review and meta-analysis of data from more than 2.4 million individuals has revealed that Māori people with diabetes have a higher risk of all-cause mortality than White people with diabetes. The analysis included 23 prospective cohort studies that reported risks for diabetic complications and all-cause mortality according to racial/ethnic group, published up until May 2021. Hazard ratio (HR) estimates were pooled using a random-effects inverse-variance model. Racial/ethnic groups were White (59.3%), Black (11.2%), Asian (1.3%), Hispanic-American (2.4%), Native American (0.2%), East Asian (1.9%), South Asian (0.8%), Pacific Islander (2.3%), Māori (2.4%) and Other (18.2%). Compared with White people, the HR for allcause mortality in Māori people was 1.88 (95% CI 1.61- 2.21). Hispanic-American people had a significantly lower risk for cardiovascular disease (HR 0.66; 95% CI 0.53-0.81) and Black people had a higher risk for end-stage renal disease (HR 1.54; 95% CI 1.05-2.24) compared with White people.
