Abstract：
To systematically review the research conducted on prevalence of frailty and prefrailty among community-dwelling older adults in low-income and middle-income countries (LMICs) and to estimate the pooled prevalence of frailty and prefrailty in community-dwelling older adults in LMICs.
Systematic review and meta-analysis. PROSPERO registration number is CRD42016036083.
MEDLINE, EMBASE, AMED, Web of Science, CINAHL and WHO Global Health Library were searched from their inception to 12 September 2017.
Low-income and middle-income countries.
Community-dwelling older adults aged ≥60 years.
We screened 7057 citations and 56 studies were included. Forty-seven and 42 studies were included in the frailty and prefrailty meta-analysis, respectively. The majority of studies were from upper middle-income countries. One study was available from low-income countries. The prevalence of frailty varied from 3.9% (China) to 51.4% (Cuba) and prevalence of prefrailty ranged from 13.4% (Tanzania) to 71.6% (Brazil). The pooled prevalence of frailty was 17.4% (95% CI 14.4% to 20.7%, I2=99.2%) and prefrailty was 49.3% (95% CI 46.4% to 52.2%, I2=97.5%). The wide variation in prevalence rates across studies was largely explained by differences in frailty assessment method and the geographic region. These findings are for the studies with a minimum recruitment age 60, 65 and 70 years.
The prevalence of frailty and prefrailty appears higher in community-dwelling older adults in upper middle-income countries compared with high-income countries, which has important implications for healthcare planning. There is limited evidence on frailty prevalence in lower middle-income and low-income countries.

摘要：
系统回顾低收入和中等收入国家（LMICs）社区居住老年人的脆弱和脆弱患病率的研究，并估计LMICs社区居住老年人的脆弱和脆弱患病率。
系统评价和荟萃分析。PROSPERO注册号是CRD42016036083。
MEDLINE,EMBASE,AMED,WebofScience,从成立至2017年9月12日，对CINAHL和世卫组织全球卫生图书馆进行了检索。
低收入和中等收入国家。
≥60岁的社区居住老年人。
我们筛选了7057篇引文，纳入了56篇研究。47和42项研究被纳入脆弱和脆弱荟萃分析，分别。大多数研究来自中高收入国家。低收入国家提供了一项研究。脆弱的患病率从3.9％（中国）到51.4％（古巴），脆弱的患病率从13.4％（坦桑尼亚）到71.6％（巴西）。合并的虚弱患病率为17.4%(95%CI为14.4%至20.7%，I2=99.2%)，优先等级为49.3%(95%CI46.4%至52.2%，I2=97.5%)。研究中患病率的巨大差异在很大程度上可以解释为脆弱评估方法和地理区域的差异。这些发现适用于最低招募年龄为60岁、65岁和70岁的研究。
与高收入国家相比，上中等收入国家的社区居住老年人的身体虚弱患病率更高，这对医疗保健规划具有重要意义。在中低收入国家和低收入国家中，脆弱患病率的证据有限。
