Background <p>Cardiovascular disease mortality among Asian American subgroups has worsened in recent decades. One understudied contributor is the role of discrimination and its impact on lifestyle risk factors that influence cardiovascular health. This scoping review synthesizes the literature on the associations between interpersonal discrimination and three key lifestyle risk factors that are crucial to cardiovascular health: smoking, exercise, and sleep.</p> Methods <p>We searched four databases (PubMed/Embase/CINAHL Complete/PsycINFO) for studies published prior to 2/13/2026, supplemented by hand-searching reference lists of included articles. Eligible studies explored the association between interpersonal discrimination and smoking, exercise, or sleep among Asian Americans.</p> Results <p>Our search returned 1,935 studies, of which 1,912 were excluded. We conducted a full-text review with 23 articles, yielding 16 eligible studies. Five studies examined discrimination and smoking, three examined discrimination and exercise, and 10 examined discrimination and sleep health. Many of the included studies had small samples, varied methods, and high risk of bias. Among these risk factors, most of the evidence suggests poor sleep health is related to discrimination against Asian Americans.</p> Conclusion <p>Interpersonal discrimination is linked to adverse lifestyle risk factors, especially poor sleep health, highlighting underrecognized contributors to cardiovascular health disparities among Asian Americans. Larger studies that disaggregate Asian American subgroups with validated assessments of discrimination and related risk behaviors are needed, along with more language-concordant surveys to better capture the experiences of those with limited English proficiency. Healthcare professionals, public health officials, and researchers must work collaboratively to address discrimination and reduce its harmful downstream effects.</p>
