This study described the functional status of people with COPD using the 1-min sit-to-stand test (1minSTS) over a 6-month period and the examined sociodemographic and clinical characteristics associated with this outcome. Data from a prospective study including people with COPD were analyzed. Functional status was assessed monthly with the 1minSTS over 6 months. Linear-mixed effect models assessed the 1minSTS number of repetitions mean change. One-hundred and eight participants (82.4% men; 66.9 \u00b1 9.5 years) were included. A significantly lower number of repetitions in the 1minSTS over the 6-month period was associated with being female (estimate: \u22124.69, 95%CI: \u22128.20; \u22121.18), being older (estimate: \u22120.56, 95%CI: \u22120.77; \u22120.34), having higher BMI (estimate: \u22120.55, 95%CI: \u22120.81; \u22120.28) and having higher activity-related dyspnea (estimate: \u22122.04, 95%CI: \u22123.25; \u22120.83). Half of the participants showed improvements above three repetitions in the 1minSTS over the 6-month period, independently of their baseline impairment (1minSTS &lt; 70% predicted: 52.5%; \u226570% predicted: 54.4%). To conclude, monthly follow-up assessments were associated with clinically relevant benefits in the functional status of people with COPD. Age, body composition, and activity-related dyspnea were the main predictors of functional status over time. Further research is needed to corroborate our findings and to support the beneficial effects of regular COPD monitoring.<\/jats:p>","DOI":"10.3390\/jcm11113052","type":"journal-article","created":{"date-parts":[[2022,5,29]],"date-time":"2022-05-29T08:50:51Z","timestamp":1653814251000},"page":"3052","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Monthly Follow-Ups of Functional Status in People with COPD: A Longitudinal Study"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7928-6387","authenticated-orcid":false,"given":"V\u00e2nia","family":"Rocha","sequence":"first","affiliation":[{"name":"Respiratory Research and Rehabilitation Laboratory (Lab3R), School of Health Sciences (ESSUA), University of Aveiro, 3810-193 Aveiro, Portugal"},{"name":"Institute of Biomedicine (iBiMED), University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5721-4550","authenticated-orcid":false,"given":"Jorge","family":"Cabral","sequence":"additional","affiliation":[{"name":"Center for Research & Development in Mathematics and Applications (CIDMA), Department of Mathematics, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5984-4844","authenticated-orcid":false,"given":"Sara","family":"Souto-Miranda","sequence":"additional","affiliation":[{"name":"Respiratory Research and Rehabilitation Laboratory (Lab3R), School of Health Sciences (ESSUA), University of Aveiro, 3810-193 Aveiro, Portugal"},{"name":"Institute of Biomedicine (iBiMED), University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4427-2695","authenticated-orcid":false,"given":"Ana Filipa","family":"Machado","sequence":"additional","affiliation":[{"name":"Respiratory Research and Rehabilitation Laboratory (Lab3R), School of Health Sciences (ESSUA), University of Aveiro, 3810-193 Aveiro, Portugal"},{"name":"Institute of Biomedicine (iBiMED), University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1151-8791","authenticated-orcid":false,"given":"Cristina","family":"J\u00e1come","sequence":"additional","affiliation":[{"name":"Center for Health Technology and Services Research (CINTESIS), Faculty of Medicine, University of Porto (FMUP), 4200-450 Porto, Portugal"},{"name":"Department of Community Medicine, Information and Health Decision Sciences (MEDCIDS), Faculty of Medicine, University of Porto (FMUP), 4200-450 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4911-4469","authenticated-orcid":false,"given":"Joana","family":"Cruz","sequence":"additional","affiliation":[{"name":"Respiratory Research and Rehabilitation Laboratory (Lab3R), School of Health Sciences (ESSUA), University of Aveiro, 3810-193 Aveiro, Portugal"},{"name":"ciTechCare-Center for Innovative Care and Health Technology, School of Health Sciences (ESSLei), Polytechnic of Leiria, 2411-901 Leiria, Portugal"}]},{"given":"Vit\u00f3ria","family":"Martins","sequence":"additional","affiliation":[{"name":"Pulmonology Department, Hospital Distrital da Figueira da Foz, 3094-001 Figueira da Foz, Portugal"}]},{"given":"Paula","family":"Sim\u00e3o","sequence":"additional","affiliation":[{"name":"Pulmonology Department, Unidade Local de Sa\u00fade de Matosinhos, 4450-021 Matosinhos, Portugal"}]},{"given":"Maria Aurora","family":"Mendes","sequence":"additional","affiliation":[{"name":"Respiratory Research and Rehabilitation Laboratory (Lab3R), School of Health Sciences (ESSUA), University of Aveiro, 3810-193 Aveiro, Portugal"},{"name":"Pulmonology Department, Centro Hospitalar do Baixo Vouga (CHBV), 3810-096 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1051-8084","authenticated-orcid":false,"given":"Vera","family":"Afreixo","sequence":"additional","affiliation":[{"name":"Center for Research & Development in Mathematics and Applications (CIDMA), Department of Mathematics, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4980-6200","authenticated-orcid":false,"given":"Alda","family":"Marques","sequence":"additional","affiliation":[{"name":"Respiratory Research and Rehabilitation Laboratory (Lab3R), School of Health Sciences (ESSUA), University of Aveiro, 3810-193 Aveiro, Portugal"},{"name":"Institute of Biomedicine (iBiMED), University of Aveiro, 3810-193 Aveiro, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,28]]},"reference":[{"key":"ref_1","unstructured":"World Health Organization (2021).
