We aimed to estimate the prevalence of multimorbidity, and analyze the health service use of middle\u2010aged and older persons with multimorbidity in urban China.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Study participants included 3737 urban residents aged \u226545\u2009years from the China Health and Retirement Longitudinal Study 2011. A total of 16 pre\u2010specified self\u2010reported chronic conditions were used to measure multimorbidity, which was defined as having two or more conditions. Logistic regression was used to analyze the characteristics and health service use of persons with multimorbidity. Analyses were weighted to adjust for sampling design and non\u2010response.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of the study population, 51.9% were men and 20.1% were aged &gt;70\u2009years. Hypertension (33.1%) was the most prevalent condition, followed by arthritis (25.4%), digestive disease (18.7%), dyslipidemia (18.3%) and heart disease (17.7%). The prevalence of multimorbidity was 45.5% (95% CI 41.4\u201349.7%). Multivariate analyses showed that the prevalence of multimorbidity was significantly higher in respondents who are older and socioeconomically disadvantaged than that in their counterparts. Multimorbid patients used 72.7% of outpatient services and 77.3% of inpatient services. After controlling for demographic, socioeconomic, health behavior and health insurance factors, condition counts still had a positive relationship with outpatient or inpatient service use.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The burden of multimorbidity is high among the middle\u2010aged and older urban Chinese population. Management of multimorbidity therefore deserves more attention from health policymakers, providers and educators of health professionals in China and in other low\u2010 and middle\u2010income countries. <jats:bold>Geriatr Gerontol Int 2018; 18: 1447\u20131452<\/jats:bold>.<\/jats:p><\/jats:sec>","DOI":"10.1111\/ggi.13510","type":"journal-article","created":{"date-parts":[[2018,9,4]],"date-time":"2018-09-04T07:48:59Z","timestamp":1536047339000},"page":"1447-1452","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":68,"title":["Multimorbidity among middle\u2010aged and older persons in urban China: Prevalence, characteristics and health service utilization"],"prefix":"10.1111","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7137-5596","authenticated-orcid":false,"given":"He","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Global Health, School of Public Health Peking University  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2786-8283","authenticated-orcid":false,"given":"Mengling","family":"Cheng","sequence":"additional","affiliation":[{"name":"Department of Sociology Peking University  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Zhuang","sequence":"additional","affiliation":[{"name":"Department of Global Health, School of Public Health Peking University  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joanna B","family":"Broad","sequence":"additional","affiliation":[{"name":"Department of Geriatric Medicine University of Auckland  Auckland New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2018,9,4]]},"reference":[{"key":"e_1_2_7_2_1","unstructured":"The Academy of Medical Sciences (UK).Multimorbidity: a priority for global health research2018.
