High WC was associated with greater mortality risk in males (HR, 1.24 [95% CI, 1.07\u20131.44]). Similar patterns were observed in females. In joint BMI\u2010WC analyses, overweight regardless of WC status and class I and II obesity with high WC were associated with lower mortality risk among males. Being underweight, regardless of WC status, and having normal weight with high WC were both associated with higher mortality risk in both sexes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>These findings highlight the adverse association of central adiposity and the limitations of BMI\u2010only classification for mortality risk stratification in older adults.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/jgs.70600","type":"journal-article","created":{"date-parts":[[2026,8,19]],"date-time":"2026-08-19T07:01:22Z","timestamp":1787122882000},"page":"2870-2877","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Time\u2010Varying Body Mass Index, Waist Circumference and All\u2010Cause Mortality in\n                    <scp>US<\/scp>\n                    Adults Aged 65 or Older"],"prefix":"10.1111","volume":"74","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4377-6461","authenticated-orcid":false,"given":"Furong","family":"Xu","sequence":"first","affiliation":[{"name":"College of Education University of Rhode Island  Kingston Rhode Island USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jacob E.","family":"Earp","sequence":"additional","affiliation":[{"name":"Department of Kinesiology University of Connecticut  Storrs Connecticut USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bryan J","family":"Blissmer","sequence":"additional","affiliation":[{"name":"Department of Kinesiology University of Rhode Island  Kingston Rhode Island USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julie","family":"Coiro","sequence":"additional","affiliation":[{"name":"College of Education University of Rhode Island  Kingston Rhode Island USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steven A.","family":"Cohen","sequence":"additional","affiliation":[{"name":"Department of Public Health University of Rhode Island  Kingston Rhode Island USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Geoffrey W.","family":"Greene","sequence":"additional","affiliation":[{"name":"Department of Nutrition University of Rhode Island  Kingston Rhode Island USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,19]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIR.0000000000000973"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.3390\/jcm13082305"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1093\/ije\/dys008"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0177175"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.111.067264"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1093\/ajcn\/79.3.379"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41574\u2010019\u20100310"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2012.113905"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.3945\/ajcn.113.068122"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0052111"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.clnesp.2025.03.051"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/oby.20666"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.1007\/s13679\u2010024\u201000580\u20101"},{"key":"e_1_2_10_15_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1749\u20106632.2000.tb06506.x"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.afos.2021.01.001"},{"key":"e_1_2_10_17_1","doi-asserted-by":"publisher","DOI":"10.1001\/archinternmed.2010.201"},{"key":"e_1_2_10_18_1","doi-asserted-by":"publisher","DOI":"10.7326\/M14\u20102525"},{"key":"e_1_2_10_19_1","doi-asserted-by":"publisher","DOI":"10.3389\/fcvm.2022.816144"},{"key":"e_1_2_10_20_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12872\u2010019\u20101223\u2010z"},{"key":"e_1_2_10_21_1","doi-asserted-by":"publisher","DOI":"10.1016\/S2213\u20108587(24)00316\u20104"},{"key":"e_1_2_10_22_1","doi-asserted-by":"publisher","DOI":"10.1038\/oby.2003.123"},{"key":"e_1_2_10_23_1","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehae206"},{"key":"e_1_2_10_24_1","doi-asserted-by":"publisher","DOI":"10.1002\/oby.21028"},{"key":"e_1_2_10_25_1","unstructured":"National Health and Aging Trends Study.
