However, the associations of MCR with frailty risk and its reversibility remain unclear.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A longitudinal study was conducted of 10\u2009809 older adults from the Health and Retirement Study in the United States. Frailty was assessed by the frailty index and reversibility was measured by transitions from frailty at baseline to non\u2010frailty during follow\u2010up. MCR was defined as the presence of both subjective cognitive complaints and slow gait speed in individuals without dementia or mobility disability. Multistate Markov models were performed to evaluate the effects of MCR on transitions among non\u2010frailty, frailty and death. Cox regression models were used to estimate MCR associated with the risk of frailty and the likelihood of reversion.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Among 10\u2009809 participants with a median age of 71 (interquartile range: 67\u201371) years and 6462 (57.93%) females, a total of 105\u2009372 person\u2010years (9.75\u2009years in average) were followed up. The prevalence of MCR at baseline in non\u2010frail and frail participants was 3.12% and 18.56%, respectively. Compared with non\u2010MCR, MCR increased the probability of transitioning from non\u2010frailty to frailty by 46% (HR\u2009=\u20091.46, 95% CI: 1.27\u20131.67) and decreased the probability of transitioning from frailty to non\u2010frailty by 36% (HR\u2009=\u20090.64, 95% CI: 0.52\u20130.77). Compared with normal function, subjective cognitive complaints only, slow gait speed only and MCR increased the probability of transitioning from non\u2010frailty to frailty by 43% (HR\u2009=\u20091.43, 95% CI: 1.33\u20131.53), 14% (HR\u2009=\u20091.14, 95% CI: 1.00\u20131.30) and 69% (HR\u2009=\u20091.69, 95% CI: 1.47\u20131.96) and decreased the probability of transitioning from frailty to non\u2010frailty by 18% (HR\u2009=\u20090.82, 95% CI: 0.74\u20130.92), 27% (HR\u2009=\u20090.73, 95% CI: 0.60\u20130.88) and 45% (HR\u2009=\u20090.55, 95% CI: 0.45\u20130.67), respectively. As shown in the prospective analyses, MCR and its single component were associated with increased frailty risk and decreased likelihood of reversion.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>MCR is associated with an increased risk of frailty, accelerated transition from non\u2010frailty to frailty and a decreased likelihood of reversion from frailty. MCR emerges as a promising risk stratification factor for frailty, highlighting the need for increased focus on individuals with MCR, particularly within the pre\u2010frail population.<\/jats:p><\/jats:sec>","DOI":"10.1002\/jcsm.70033","type":"journal-article","created":{"date-parts":[[2025,7,29]],"date-time":"2025-07-29T07:59:18Z","timestamp":1753775958000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Motoric Cognitive Risk Syndrome Associated With Risk of Frailty and Likelihood of Reversion in Older Adults"],"prefix":"10.1002","volume":"16","author":[{"given":"Dingchun","family":"Hou","sequence":"first","affiliation":[{"name":"Institute of Population Research, Peking University  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bo","family":"Liang","sequence":"additional","affiliation":[{"name":"Institute of Population Research, Peking University  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lijun","family":"Pei","sequence":"additional","affiliation":[{"name":"Institute of Population Research, Peking University  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gong","family":"Chen","sequence":"additional","affiliation":[{"name":"Institute of Population Research, Peking University  Beijing China"},{"name":"Institute of Ageing Studies, Peking University  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,7,29]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(19)31786-6"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s12603-019-1273-z"},{"key":"e_1_2_12_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S2468-2667(18)30091-4"},{"key":"e_1_2_12_5_1","doi-asserted-by":"publisher","DOI":"10.1093\/ageing\/afaa219"},{"key":"e_1_2_12_6_1","doi-asserted-by":"publisher","DOI":"10.1093\/gerona\/gls191"},{"key":"e_1_2_12_7_1","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.0000000000000717"},{"key":"e_1_2_12_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/jcsm.12476"},{"key":"e_1_2_12_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/alz.13696"},{"key":"e_1_2_12_10_1","doi-asserted-by":"publisher","DOI":"10.1152\/physrev.00037.2021"},{"key":"e_1_2_12_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.arr.2024.102461"},{"key":"e_1_2_12_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/joim.20068"},{"key":"e_1_2_12_13_1","doi-asserted-by":"publisher","DOI":"10.1038\/s43587-020-00017-z"},{"key":"e_1_2_12_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jalz.2019.03.011"},{"key":"e_1_2_12_15_1","doi-asserted-by":"publisher","DOI":"10.1093\/gerona\/glae038"},{"key":"e_1_2_12_16_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12877-020-01511-0"},{"key":"e_1_2_12_17_1","doi-asserted-by":"publisher","DOI":"10.3233\/JAD-190517"},{"key":"e_1_2_12_18_1","doi-asserted-by":"publisher","DOI":"10.1016\/S2666-7568(24)00033-3"},{"key":"e_1_2_12_19_1","doi-asserted-by":"publisher","DOI":"10.1002\/alz.12793"},{"key":"e_1_2_12_20_1","doi-asserted-by":"publisher","DOI":"10.1093\/ije\/dyu067"},{"key":"e_1_2_12_21_1","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehad885"},{"key":"e_1_2_12_22_1","doi-asserted-by":"publisher","DOI":"10.1093\/ageing\/afad221"},{"key":"e_1_2_12_23_1","doi-asserted-by":"publisher","DOI":"10.1186\/s40537-021-00516-9"},{"key":"e_1_2_12_24_1","doi-asserted-by":"publisher","DOI":"10.1002\/alz.12521"},{"key":"e_1_2_12_25_1","doi-asserted-by":"publisher","DOI":"10.18637\/jss.v038.i08"},{"key":"e_1_2_12_26_1","doi-asserted-by":"publisher","DOI":"10.1111\/ene.13331"},{"key":"e_1_2_12_27_1","doi-asserted-by":"publisher","DOI":"10.1093\/ageing\/afy169"},{"key":"e_1_2_12_28_1","doi-asserted-by":"publisher","DOI":"10.1002\/alz.14232"},{"key":"e_1_2_12_29_1","doi-asserted-by":"publisher","DOI":"10.1001\/jamanetworkopen.2019.13123"},{"key":"e_1_2_12_30_1","first-page":"1218","article-title":"Environmental and Climate Impacts on Physiological Aging: Comprehensive Pathways to Enhanced Age\u2010Related Resilience","volume":"16","author":"Zhang C.
