BACKGROUND An ageing population worldwide needs to investigate quality of life (QoL) and level of functioning (LoF) in the elderly and its associated variables. We aimed to study the relationship between Quality of Life (QoL) and Level of Functioning (LoF) in an elderly population in Europe. METHOD As part of the Ment_Dis65+ European Project, 3142 community-dwelling adults aged 65-84 years in six countries were assessed by using the adaptation for the elderly of the Composite International Diagnostic Interview (CIDI65+) to provide psychiatric diagnosis according to the International Classification of Diseases (10th edition) (ICD-10 Classification of Mental and Behavioural Disorders). Socio-demographic and clinical interviews, and two self-report tools, the World Health Organization QoL assessment (WHO QoL BREF), to assess QoL, and the WHO Disability Assessment Schedule -II (WHODAS-II), to assess LoF, were also administered. RESULTS Most subjects reported good levels of QoL (56.6%) and self-rated health (62%), with no or mild disability (58.8%). There was a linear decrease of the QoL and the LoF by increase of age. Elderly with ICD-10 mental disorder (e.g. somatoform, affective and anxiety disorders) had poorer QoL and lower LoF. There were a number of predictors of lower levels of QoL and disability, including both socio-demographic variables (e.g. male gender, increase in age, poor financial situation, retirement, reduced number of close significant others), ICD-10 psychiatric diagnosis (mainly anxiety, somatoform disorders) and presence of medical disorders (mainly heart and respiratory diseases). CONCLUSIONS The study indicates that QoL and LoF were quite acceptable in European elderly people. A series of variables, including psychiatric and somatic disorders, as well as socio-demographic factor influenced in a negative way both QoL and LoF. More specific links between mental health, social and health services dedicated to this segment of the population, should be implemented in order to provide better care for elderly people with conditions impacting their QoL and functioning.

生活质量，功能水平及其与老年人精神和身体疾病的关系：MentDis_ICF65 +研究的结果。

背景技术全球人口老龄化需要调查老年人的生活质量（QoL）和功能水平（LoF）及其相关变量。我们旨在研究欧洲老年人口的生活质量（QoL）与功能水平（LoF）之间的关系。方法作为欧洲Ment_Dis65 +项目的一部分，根据国际分类法（CIDI65 +）对老年人进行了改编，对六个国家的3142位65-84岁的社区成年人进行了评估，以提供精神病诊断。疾病（第10版）（ICD-10精神和行为障碍分类）。社会人口统计学和临床​​访谈，以及两种自我报告工具，即世界卫生组织QoL评估（WHO QoL BREF），用于评估QoL，还管理了评估LoF的WHO残疾评估时间表II（WHODAS-II）。结果大多数受试者的QoL（56.6％）和自我评估的健康状况（62％）良好，无或有轻度残疾（58.8％）。随着年龄的增长，QoL和LoF呈线性下降。患有ICD-10精神障碍（例如躯体形式，情感和焦虑症）的老年人的QoL较差，LoF较低。存在许多QoL和残疾水平较低的预测因素，包括社会人口统计学变量（例如，男性，年龄增加，财务状况不佳，退休，其他近亲有意义的人数减少），ICD-10精神病学诊断（主要是焦虑症，躯体形式疾病）和医疗疾病（主要是心脏病和呼吸道疾病）的存在。结论该研究表明，QoL和LoF在欧洲老年人中是可以接受的。一系列变量，包括精神疾病和躯体疾病，以及社会人口统计学因素均对QoL和LoF产生负面影响。应该实施针对这一人群的精神卫生，社会和卫生服务之间的更具体的联系，以便为影响其生活质量和功能的老年人提供更好的护理。
