While lifestyle factors influence health outcomes, their combined association with IC remains understudied. Objective: To examine the association between a Healthy Lifestyle Score (HLS) and intrinsic capacity in older adults in Singapore. Methods: Data from a population-based sample of older adults aged \u226560 years in the Queenstown district of Singapore was analysed. The HLS (range 0\u20135) included smoking, alcohol use, physical activity, sleep quality, and BMI (Asian cut-offs). IC was measured using the WHO ICOPE framework and defined as the presence of one or more deficits. Results: A total of 1644 participants were included (mean age 72.1 years, 56.4% women). IC deficits were present in 50.9% of the cohort. Based on HLS, 29.9% were classified as unhealthy (0\u20132), 41.4% intermediate (3), and 28.6% healthy (4\u20135). HLS category was significantly associated with IC deficits (p = 0.004). Among participants with healthy lifestyles, 55.6% had no IC deficits, compared to 47.0% in the intermediate and 45.9% in the unhealthy groups. Only 13.9% met recommended physical activity levels; 58.3% had an unhealthy BMI, 20.0% consumed alcohol, 8.1% were smokers, and 31.7% reported insufficient sleep. Conclusions: Healthier lifestyle profiles are significantly associated with fewer IC deficits. These findings underscore the importance of promoting modifiable health behaviours to preserve intrinsic capacity and support healthy ageing.<\/jats:p>","DOI":"10.3390\/nu18060918","type":"journal-article","created":{"date-parts":[[2026,3,16]],"date-time":"2026-03-16T13:32:07Z","timestamp":1773667927000},"page":"918","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Association Between Healthy Lifestyle Habits and Intrinsic Capacity Among Community-Dwelling Older Adults in Singapore"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5745-6517","authenticated-orcid":false,"given":"Jeremy","family":"Teng Jun Wei","sequence":"first","affiliation":[{"name":"Division of Geriatric Medicine, Alexandra Hospital, 378 Alexandra Road, Singapore 159964, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6966-6087","authenticated-orcid":false,"given":"Shuna S.","family":"Khoo","sequence":"additional","affiliation":[{"name":"Department of Psychology, Faculty of Arts and Social Sciences, National University of Singapore, 9 Arts Link, Singapore 117570, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9032-0184","authenticated-orcid":false,"given":"Reshma A.","family":"Merchant","sequence":"additional","affiliation":[{"name":"Division of Geriatric Medicine, National University Hospital, 1E Kent Ridge Road, Singapore 119228, Singapore"},{"name":"Yong Loo Lin School of Medicine, National University of Singapore, 10 Medical Drive, Singapore 117597, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Li Feng","family":"Tan","sequence":"additional","affiliation":[{"name":"Division of Geriatric Medicine, Alexandra Hospital, 378 Alexandra Road, Singapore 159964, Singapore"},{"name":"Yong Loo Lin School of Medicine, National University of Singapore, 10 Medical Drive, Singapore 117597, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lile","family":"Jia","sequence":"additional","affiliation":[{"name":"Department of Psychology, Faculty of Arts and Social Sciences, National University of Singapore, 9 Arts Link, Singapore 117570, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"on behalf of the Health District @ Queenstown","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2145","DOI":"10.1016\/S0140-6736(15)00516-4","article-title":"The World report on ageing and health: A policy framework for healthy ageing","volume":"387","author":"Beard","year":"2016","journal-title":"Lancet"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1358","DOI":"10.1038\/s43587-025-00915-0","article-title":"Disease burden, lifetime healthcare cost and long-term intervention impact projections among older adults in Singapore","volume":"5","author":"Guo","year":"2025","journal-title":"Nat.
