The burden of multimorbidity is increasing worldwide; however, little is known about trends in multimorbidity prevalence among Chinese older adults. We aimed to estimate the prevalence and trends of multimorbidity in community-dwelling older adults in Beijing.
Longitudinal.
Residents of Beijing aged ≥60 years.
Data were derived from the Beijing Longitudinal Study of Aging, using cluster, stratification, and random sampling. A total of 1842, 2914, and 1837 participants were included in the 2004, 2011, and 2017 sample, respectively. Multimorbidity was defined as the presence of two or more chronic conditions. Trends in multimorbidity were examined by age, sex, and geographical area.
The prevalence of multimorbidity was 32.5%, 52.9%, and 53.2% in 2004, 2011, and 2017, respectively, following an upward trend over time (P =0.003). A similar multimorbidity increase trend was present in age-, sex-, and region-stratified analysis for the 2004-2017 period (all P<0.05). The most common chronic diseases in 2004 were hypertension (34.3%), cataract (18.2%), coronary heart disease (CHD) (15.6%), stroke (14.3%), and chronic obstructive pulmonary disease (7.9%); in 2011, these were hypertension (49.6%), arthritis (30.9%), CHD (22.3%), stroke (21.9%), and diabetes (15.1%); in 2017, these were hypertension (54.4%), arthritis (26.3%), stroke (22.6%), cataract (20.5%), and CHD (20.1%). The proportion of older adults diagnosed with ≥3 chronic diseases significantly increased from 13.4% in 2004 to 73.1% in 2011 and 69.5% in 2017.
Multimorbidity is common and the overall and age-, sex-, and region-specific multimorbidity prevalence has been increasing over the past 13 years. Public health policies should account for the more complex care needs and growing costs associated with increasing prevalence of chronic disease and multimorbidity in Chinese older adults.
全球范围内的多种疾病负担正在增加；然而，关于中国老年人多种疾病患病率的趋势知之甚少。本研究旨在估计北京市社区老年人的多种疾病患病率及其趋势。
纵向研究。
年龄≥60 岁的北京市居民。
数据来自北京老龄化纵向研究，采用聚类、分层和随机抽样。分别有 1842、2914 和 1837 名参与者纳入 2004、2011 和 2017 年的样本。多种疾病定义为存在两种或两种以上的慢性疾病。通过年龄、性别和地理区域来检查多种疾病的趋势。
2004 年、2011 年和 2017 年的多种疾病患病率分别为 32.5%、52.9%和 53.2%，呈逐年上升趋势（P=0.003）。2004-2017 年期间，按年龄、性别和地区分层分析，也存在相似的多种疾病上升趋势（均 P<0.05）。2004 年最常见的慢性疾病为高血压（34.3%）、白内障（18.2%）、冠心病（CHD）（15.6%）、中风（14.3%）和慢性阻塞性肺疾病（7.9%）；2011 年为高血压（49.6%）、关节炎（30.9%）、CHD（22.3%）、中风（21.9%）和糖尿病（15.1%）；2017 年为高血压（54.4%）、关节炎（26.3%）、中风（22.6%）、白内障（20.5%）和 CHD（20.1%）。诊断患有≥3 种慢性疾病的老年人比例从 2004 年的 13.4%显著增加到 2011 年的 73.1%和 2017 年的 69.5%。
多种疾病很常见，过去 13 年来，总体和年龄、性别及地区特定的多种疾病患病率一直在增加。公共卫生政策应考虑到与中国老年人慢性疾病和多种疾病患病率增加相关的更复杂的护理需求和不断增长的成本。
