Using multivariable-adjusted Cox proportional hazards regression, we estimated hazards ratios (HR) and 95% confidence intervals (CI), stratified by race\/ethnicity, Asian ethnicity, menopausal status, and hormone receptor status.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>With 2,594 overall deaths and 1,120 BC deaths, all-cause mortality risk increased with higher BMI (per 5\u2009kg\/m2) in both Asian American (HR\u2009=\u20091.13, 95%CI=1.05-1.21) and non-Latina White (HR\u2009=\u20091.09, 95%CI=1.04-1.14) women. In the subset with abdominal adiposity measures (1,427 overall and 641 BC deaths), the range of HRs per unit increase was similar for Asian American (1.18 to 1.34) and White (1.14 to 1.19) women. For both overall and abdominal obesity, with a few exceptions, associations were observed primarily for postmenopausal women with hormone receptor-positive BC, although heterogeneity was not statistically significant. The survival difference between Asian American and non-Latina White women remained after adjustment for BMI (HR\u2009=\u20090.88, 95%CI=0.78-0.997). Obesity measures were not associated with BC-specific mortality, except for WHR and WHtR in Chinese women.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Our findings suggest that differences in overall and abdominal obesity do not explain the BC survival differences between the two populations.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1093\/jnci\/djag348","type":"journal-article","created":{"date-parts":[[2026,9,26]],"date-time":"2026-09-26T12:17:32Z","timestamp":1790425052000},"source":"Crossref","is-referenced-by-count":0,"title":["Obesity and survival of Asian American and White women with breast cancer"],"prefix":"10.1093","author":[{"given":"Esther M","family":"John","sequence":"first","affiliation":[{"name":"Stanford University School of Medicine Department of Epidemiology & Population Health, , Stanford, CA,","place":["USA"]},{"name":"Stanford University School of Medicine Department of Medicine (Oncology), , Stanford, CA,","place":["USA"]},{"name":"Stanford University School of Medicine Stanford Cancer Institute, , Stanford CA,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marilyn L","family":"Kwan","sequence":"additional","affiliation":[{"name":"Kaiser Permanente Northern California Division of Research, , Pleasanton, CA,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jocelyn","family":"Koo","sequence":"additional","affiliation":[{"name":"Stanford University School of Medicine Stanford Cancer Institute, , Stanford CA,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julie","family":"Von Behren","sequence":"additional","affiliation":[{"name":"University of California Department of Epidemiology and Biostatistics, , San Francisco, San Francisco, CA,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Valerie","family":"McGuire","sequence":"additional","affiliation":[{"name":"University of California Department of Epidemiology and Biostatistics, , San Francisco, San Francisco, CA,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mi-Ok","family":"Kim","sequence":"additional","affiliation":[{"name":"University of California Department of Epidemiology and Biostatistics, , San Francisco, San Francisco, CA,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Allison W","family":"Kurian","sequence":"additional","affiliation":[{"name":"Stanford University School of Medicine Department of Epidemiology & Population Health, , Stanford, CA,","place":["USA"]},{"name":"Stanford University School of Medicine Department of Medicine (Oncology), , Stanford, CA,","place":["USA"]},{"name":"Stanford University School of Medicine Stanford Cancer Institute, , Stanford CA,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brittany N","family":"Morey","sequence":"additional","affiliation":[{"name":"University of California Department of Health, Society, & Behavior, Joe C.
