We examined associations between housing conditions (access to outdoor spaces, urbanicity, household density, and household composition) and changes in mental health (mental well-being, Quality of Life (QoL) and loneliness). We report results from multivariate linear and logistic regression models. Youth without access to outdoor spaces experienced greater declines in mental well-being (vs. garden; mean difference: \u2212\u20090\u00b775 (95% CI \u2212\u20091\u00b714, \u2212\u20090\u00b736)), and correspondingly greater odds of onset of\u00a0low mental well-being (vs. garden; OR: 1\u00b772 (95% CI 1\u00b720, 2\u00b748)). Youth in higher density households vs. below median or living alone vs. with parents only also had greater odds of onset of\u00a0low mental well-being (OR: 1\u00b726 (95% CI 1\u00b708, 1\u00b746) and OR: 1\u00b762 (95% CI 1\u00b717, 2\u00b723), respectively). Living in denser households (vs. below median; OR: 1\u00b718 (95% CI 1\u00b706, 1\u00b733), as well as living alone (vs. with parents; OR: 1\u00b738 (95% CI 1\u00b704, 1\u00b782) was associated with onset of\u00a0low QoL. Living alone more than doubled odds of\u00a0onset of loneliness compared to living with parents, OR: 2\u00b712 (95% CI 1\u00b759, 2\u00b782). Youth living alone, in denser households, and without direct access to outdoor spaces may be especially vulnerable to mental health declines.<\/jats:p>","DOI":"10.1038\/s41598-022-04909-5","type":"journal-article","created":{"date-parts":[[2022,2,4]],"date-time":"2022-02-04T06:14:57Z","timestamp":1643955297000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":35,"title":["Impact of housing conditions on changes in youth\u2019s mental health following the initial national COVID-19 lockdown: a cohort study"],"prefix":"10.1038","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8610-0963","authenticated-orcid":false,"given":"Jonathan","family":"Groot","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1404-6715","authenticated-orcid":false,"given":"Am\u00e9lie","family":"Keller","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Joensen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6376-7212","authenticated-orcid":false,"given":"Tri-Long","family":"Nguyen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4296-8488","authenticated-orcid":false,"given":"Anne-Marie","family":"Nybo Andersen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7061-3767","authenticated-orcid":false,"given":"Katrine","family":"Strandberg-Larsen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2022,2,4]]},"reference":[{"key":"4909_CR1","doi-asserted-by":"publisher","DOI":"10.1038\/s41586-020-2405-7","author":"S Flaxman","year":"2020","unstructured":"Flaxman, S. et al.
