Older adults living alone were at higher risk of reporting any depressive symptoms than those living with others (OR=1.497; P=0.039). This association was moderated by neighbourhood crowdedness, perceptible pollution, access to destinations and presence of people. Residing in neighbourhoods with lower levels of these attributes was associated with increased deleterious effects of living alone. Living in neighbourhoods with lower public transport density also increased the deleterious effects of living alone on the number of depressive symptoms. Those living alone and residing in neighbourhoods with higher levels of connectivity tended to report more depressive symptoms than their counterparts.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The level of access to destinations and social networks across Hong Kong may be sufficiently high to reduce the risk of depressive symptoms in older adults. Yet, exposure to extreme levels of public transport density and associated traffic volumes may increase the risk of depressive symptoms. The provision of good access to a variety of destinations, public transport and public open spaces for socialising in the neighbourhood may help reduce the risk of depressive symptoms in older adults who live alone.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1136\/bmjopen-2017-020480","type":"journal-article","created":{"date-parts":[[2018,3,26]],"date-time":"2018-03-26T02:10:26Z","timestamp":1522030226000},"page":"e020480","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":20,"title":["Cross-sectional associations of objectively assessed neighbourhood attributes with depressive symptoms in older adults of an ultra-dense urban environment: the Hong Kong ALECS study"],"prefix":"10.1136","volume":"8","author":[{"given":"Casper J P","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Public Health, The University of Hong Kong, Hong Kong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anthony","family":"Barnett","sequence":"additional","affiliation":[{"name":"Mary MacKillop Institute for Health Research, Australian Catholic University, Melbourne, Victoria, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cindy H P","family":"Sit","sequence":"additional","affiliation":[{"name":"Department of Sports Science and Physical Education, Faculty of Education, The Chinese University of Hong Kong, Hong Kong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Poh-chin","family":"Lai","sequence":"additional","affiliation":[{"name":"Department of Geography, Faculty of Social Sciences, The University of Hong Kong, Hong Kong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Janice M","family":"Johnston","sequence":"additional","affiliation":[{"name":"School of Public Health, The University of Hong Kong, Hong Kong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruby S Y","family":"Lee","sequence":"additional","affiliation":[{"name":"Elderly Health Service, Department of Health, The Government of Hong Kong Special Administration Region, Hong Kong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ester","family":"Cerin","sequence":"additional","affiliation":[{"name":"School of Public Health, The University of Hong Kong, Hong Kong, China"},{"name":"Mary MacKillop Institute for Health Research, Australian Catholic University, Melbourne, Victoria, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2018,3,25]]},"reference":[{"key":"2025120520410955000_8.3.e020480.1","unstructured":"World Health Organisation.
