Frailty is characterized by a functioning decline in multiple systems accompanied by an increase in individual's vulnerability to stressors. It appears to be higher in low and middle-income countries compared with high-income ones. This study aimed to evaluate the prevalence of frailty in non-institutionalized Brazilian older adults.
a systematic review and meta-analysis study.
Cross-sectional and prospective data from Brazil.
non-institutionalized adults aged 60 and older.
Electronic searches were performed in PubMed/MEDLINE, LILACS, SCOPUS and Web of Science, considering the studies published between March 2001 and July 2018, using a combination of the following terms and correlates: "elder" AND "frail" AND "prevalence" AND "Brazil". Two independent reviewers selected studies according to the inclusion criteria. Disagreements were resolved by a third reviewer (title/abstract) and by consensus. Studies with samples ≥221 subjects were considered for meta-analysis.
28 studies were included, while 18 had the data meta-analyzed. The majority of studies (61%) included older adults only from the Southeastern region. The number of subjects ranged from 53 to 5,532 individuals (N = 17,604) and the average age ranged from 65.6 to 85.5 years. The overall prevalence of frailty was 24%. When considering the different assessment methods, the prevalence was lower for frailty phenotype (16%) compared with other criteria (40%). Regarding sex, the prevalence of frailty was similar for women (28%) and men (25%). The prevalence of frailty was higher in older adults recruited from health care services (30%) compared to community ones (22%).
In Brazil, the overall prevalence of frailty in non-institutionalized older adults is higher than observed from more developed countries. However, it may vary according to the assessment methods and settings.
衰弱的特征是多个系统功能下降，同时个体对压力源的易感性增加。与高收入国家相比，中低收入国家的衰弱程度似乎更高。本研究旨在评估巴西非住院老年成年人衰弱的流行率。
系统评价和荟萃分析研究。
巴西的横断面和前瞻性数据。
年龄在 60 岁及以上的非住院成年人。
在 PubMed/MEDLINE、LILACS、SCOPUS 和 Web of Science 中进行电子检索，检索时间为 2001 年 3 月至 2018 年 7 月，使用以下术语和相关词的组合：“老年人”和“衰弱”和“流行率”和“巴西”。两名独立审查员根据纳入标准选择研究。有分歧的研究由第三名审查员（标题/摘要）和通过共识解决。只有纳入的样本≥221 例的研究才进行荟萃分析。
共纳入 28 项研究，其中 18 项进行了数据分析。大多数研究（61%）仅纳入来自东南部地区的老年成年人。研究对象人数从 53 到 5532 人不等（N=17604），平均年龄从 65.6 到 85.5 岁。衰弱的总体流行率为 24%。考虑到不同的评估方法，衰弱表型的流行率（16%）低于其他标准（40%）。关于性别，女性（28%）和男性（25%）的衰弱患病率相似。从医疗保健服务中招募的老年人（30%）比从社区招募的老年人（22%）的衰弱患病率更高。
在巴西，非住院老年成年人衰弱的总体流行率高于发达国家。然而，它可能因评估方法和环境而异。
