{"doi":"10.1093/gerona/glab044","title":"The Effect of Frailty on Walking Recovery After Hip Fracture: A Secondary Analysis of the Community Ambulation Project","abstract":"BACKGROUND: The impact of frailty on walking recovery after hip fracture has not been reported. We describe the prevalence of frailty approximately 3 months after hip fracture, and identify the impact of baseline frailty on ambulation recovery. METHODS: Data from the Community Ambulation Project, that examined the effects of 2 multicomponent home exercise programs on 6-minute walk test in participants post hip fracture, were used to reconstruct the 5-item frailty phenotype. We detailed the prevalence of frailty by subgroup and assessed the comparability between frailty groups for the categorical variable of achieving 300 m in 6-minute walk test (community ambulation threshold), and the continuous variable of total distance in 6-minute walk test before and after 16 weeks of intervention. RESULTS: Of the 210 participants, 9% were nonfrail, 59% were prefrail, and 32% were frail. The odds of a nonfrail participant achieving the 300-m threshold were 14.4 (95% CI: 2.4-87.6) times the odds of a frail participant, while a prefrail participant's odds were 6.1 (95% CI: 1.3-28.4) times after controlling for treatment group and baseline walking distance. The nonfrail participants had an increase of 92.1 m from baseline to 16 weeks, the prefrail had a 50.8 m increase, and the frail group had the smallest increase of 36.6 m (p < .001 for all). CONCLUSIONS: Prefrailty and frailty were highly prevalent in this sample of community-dwelling survivors of a recent hip fracture. Gains in walking distance and attaining a level of community ambulation were affected significantly by the level of baseline frailty.","journal":"The Journals of Gerontology Series A","year":2021,"id":190600,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":13,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.5138,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2021-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":754861,"name":"Rebecca L.
