The prevalence of usage was significantly higher (p = 0.008) for females (24.4%) than for males (14.5%). Dietary supplements were more likely to be consumed by non-smokers (p = 0.021) and those with hyperlipidemia (p = 0.003). The most popular supplement among users was calcium (53%). The majority (71%) of the users consumed supplements on a regular basis at one or more times per day, with an average duration of 2.95 (SD 4.80) years.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion<\/jats:title>\n            <jats:p>The overall prevalence of dietary supplementation in this older Chinese population was considerably lower than those in other Asia-Pacific countries.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1186\/1472-6882-9-39","type":"journal-article","created":{"date-parts":[[2009,10,20]],"date-time":"2009-10-20T06:19:46Z","timestamp":1256019586000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Dietary supplementation by older adults in southern China: a hospital outpatient clinic study"],"prefix":"10.1186","volume":"9","author":[{"given":"Wenbin","family":"Liang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andy H","family":"Lee","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Colin W","family":"Binns","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2009,10,20]]},"reference":[{"issue":"1","key":"264_CR1","doi-asserted-by":"crossref","first-page":"277S","DOI":"10.1093\/ajcn\/85.1.277S","volume":"85","author":"CL Rock","year":"2007","unstructured":"Rock CL: Multivitamin-multimineral supplements: who uses them?.
