Emotion regulation is a transdiagnostic mechanism with relevance to the etiology, maintenance, and treatment of a wide range of clinically relevant outcomes. This study applied systematic review methods to summarize the existing literature examining racial and ethnic differences in emotion regulation.
We systematically searched four electronic databases (PsycINFO, Embase, MEDLINE, and CINAHL Plus) using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.
Of the initial 1253 articles, 25 met the inclusion criteria. Findings for emotion regulation strategies generally provide evidence for racial/ethnic differences (71% of reviewed studies), with ethnoracial minorities largely exhibiting greater use of emotion regulation strategies. Whereas the results for emotion regulation potential were slightly more mixed (63% of reviewed studies found racial/ethnic differences), ethnoracial minorities were also largely found to report lower emotion regulation potential.
This review advances the literature by providing additional support for racial and ethnic differences in emotion regulation.

OBJECTIVE: The aim of this work was to quantify racial/ethnic differences in risk for future diabetic complications and all-cause mortality by performing a meta-analysis of prospective studies.
METHODS: A systematic search in PubMed and EMBASE was performed from inception to May 2021. Prospective cohort studies that reported HRs and associated 95% CIs of diabetes complications and all-cause mortality among racial/ethnic groups, with White people as the reference group, were included. Study characteristics and HR estimates were extracted from each study. Estimates were pooled using random-effects inverse-variance model with the Hartung-Knapp-Sidik-Jonkman variance estimator.
RESULTS: A total of 23 studies were included, comprising 2,416,516 individuals diagnosed with diabetes (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 others 18.2%). Compared with White individuals with diabetes, individuals of Māori ethnicity were at higher risk for all-cause mortality (HR 1.88 [95% CI 1.61, 2.21]; I2 = 7.1%), Hispanic-American individuals had a significantly lower risk for CVD (HR 0.66 [95% CI 0.53, 0.81]; I2 = 0%) and Black individuals had higher risk for end-stage renal disease (HR 1.54 [95% CI 1.05, 2.24]; I2 = 95.4%). No significant higher risk for diabetes complications was found in other racial/ethnic groups relative to White people.
CONCLUSIONS: Racial/ethnic differences exist in the risk for future diabetic complications and all-cause mortality. Our results support the use of such categories for international diabetes clinical guideline recommendations until better predictors become available. Efforts to identify high-risk groups and to better control cardiovascular risk factors across ethnically diverse populations are therefore needed.
