This study assessed the influence of multimorbidity on the phenotype transitions in frailty over time and frailty-related mortality risk.</div></div><div><h3>Methods</h3><div>Data from the Costa Rican Longevity and Healthy Aging Study Cohort (2005–2010) was used. A total of 2660 individuals aged 60 and above were included. Multimorbidity was defined as having three or more non-communicable diseases from 13 chronic conditions. Fried criteria were employed to assess frailty states (robust, pre-frail, frail). Markov-based multistate models were used to examine the impact of multimorbidity on frailty transitions and mortality over 5 years.</div></div><div><h3>Results</h3><div>Multimorbidity accelerates the transition to frailty. Compared to those with fewer than three non-communicable diseases, individuals with both multimorbidity and a prefrail state had a lower chance of recovering to robustness (HR:0.73 [95% CI: 0.54–0.99]), and a higher risk of becoming frail (HR:1.83 [95% CI: 1.43–2.34]). This translates into a 30-month earlier onset of frailty compared to individuals without chronic diseases. Multimorbidity increased the risk of all-cause mortality in those who were pre-frail (HR:1.83 [95% CI: 1.43–2.34]) but did not affect mortality risk in those who were already frail (HR:0.88 [95% CI: 0.62–1.23]).</div></div><div><h3>Conclusions</h3><div>Multimorbidity is a predictor for dynamic transitions to frailty or death. It favors the transition to “Frailty” more than to death and impacts mortality mostly in people with a “Pre-frail” state, encouraging them to explore opportunities for intervention.</div></div>","PeriodicalId":8318,"journal":{"name":"Archives of Medical Research","volume":"56 6","pages":"Article 103230"},"PeriodicalIF":4.7,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143948238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
