{"doi":"10.1093/tbm/ibab009","title":"The effects of the BAILAMOS Dance Program on hippocampal volume in older Latinos: a randomized controlled pilot study","abstract":"Hippocampal atrophy is associated with cognitive decline. Physical activity (PA) can reverse the hippocampal loss. This study investigated the effects of the 4 month BAILAMOS dance program on hippocampal volume and self-reported PA in Latinos. Participants were randomized to the BAILAMOS dance program or waitlist control group (N = 14, n = 10 intervention, n = 4 waitlist, 67 ± 6.1 years old, 70% female). Hippocampal volumes were derived from Magnetic Resonance Imaging whole-brain T1-weighted images. Participants self-reported PA through the Community Healthy Activities Model Program for Seniors Physical Activity Questionnaire for older adults. There were no statistically significant changes in hippocampal volume preintervention to postintervention (F[1, 8] = .077, p = .79, d = .05) and no associations between PA change and hippocampal volume (F[4, 13] = .71, p = .61). However, dance participants self-reported more PA (d = .54) compared to the control. These findings demonstrate that the BAILAMOS dance program did not decrease hippocampal atrophy; however, it increased self-reported PA. Future studies should include longer and more cognitively demanding interventions to determine whether dance can reduce cognitive decline through hippocampal changes.","journal":"Translational Behavioral Medicine","year":2021,"id":183833,"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":12,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9241,"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":225309,"name":"Susan Aguiñaga","orcid":"0000-0001-6717-5903","position":1,"is_corresponding":false},{"id":737746,"name":"Guilherme Moraes Balbim","orcid":"0000-0002-9059-0299","position":2,"is_corresponding":false},{"id":282469,"name":"Melissa Lamar","orcid":"0000-0001-6130-5543","position":3,"is_corresponding":false},{"id":737747,"name":"Isabela G.
