背景资料：有一个缺乏知识的两个密切相关的多维变量之间的关系：虚弱和生活质量（QOL）。本研究的目的是调查的尺寸和相关的生活质量与社区居住的老年门诊病人之间的脆弱状态。方法：我们进行了一项横断面调查，239名社区居住的门诊病人年龄65岁以上（平均年龄81.5岁）连续提到的老年医学诊所在意大利2009年6月至11月。参与者接受了全面的老年评估，包括根据骨质疏松性骨折研究（SOF）标准评估其虚弱状态，以及使用老年人生活质量（OPQOL）问卷评估生活质量。在将参与者分为“强健”（n = 72）、“虚弱前”（n = 89）和“虚弱”（n = 78）组后，使用单因素方差分析和卡方检验来寻找虚弱的相关性，包括QOL维度。进行多元线性回归分析，以找到相关的整体样本中的生活质量和“脆弱”和“强大”的participators.Results：一个负面的趋势，生活质量与脆弱的状态被发现几乎所有的生活质量（健康，独立，家庭和邻里，心理和情感健康，休闲，活动和宗教）的维度，除了社会关系和参与和财务状况。总样本中生活质量差的独立相关因素是“能量水平降低”（SOF虚弱标准）、抑郁状态、依赖性转移和洗澡能力以及金钱管理（调整后的R平方0.39）;在“虚弱”的参与者中，这种关联与抑郁状态和年轻年龄有关，而在“健壮”的参与者中，这种关联与较低的体重指数有关。五个七个维度的生活质量的负面影响，虚弱，但只有一个SOF标准的虚弱是独立相关的生活质量，校正后的年龄，功能状态和抑郁。年老体弱的老年人生活质量较好与其年龄和情感状态有关。针对体弱社区居住的老年门诊患者的生活质量的干预措施应考虑的结果，不仅健康相关的生活质量，但也生活质量的其他领域。
Background: There is a lack of knowledge concerning the relationship between two closely-linked multidimensional variables: frailty and quality of life (QOL). The aim of this study was to investigate dimensions and correlates of QOL associated with frailty status among community-dwelling older outpatients.Methods: We conducted a cross-sectional survey of 239 community-dwelling outpatients aged 65+ (mean age 81.5 years) consecutively referred to a geriatric medicine clinic in Italy between June and November 2009. Participants underwent a comprehensive geriatric assessment, including assessment of their frailty status according to the Study of Osteoporotic Fractures (SOF) criteria, and QOL, which was evaluated by using the Older People's QOL (OPQOL) questionnaire. One-way ANOVA and chi-squared tests were used to find correlates of frailty, including QOL dimensions, after stratification of participants in the "robust" (n = 72), "pre-frail" (n = 89) and "frail" (n = 78) groups. Multiple linear regression analyses were performed to find correlates of QOL in the overall sample and among "frail" and "robust" participants.Results: A negative trend of QOL with frailty status was found for almost all dimensions of QOL (health, independence, home and neighbourhood, psychological and emotional well-being, and leisure, activities and religion) except for social relationships and participation and financial circumstances. Independent correlates of a poor QOL in the total sample were "reduced energy level" (SOF criterion for frailty), depressive status, dependence in transferring and bathing abilities and money management (adjusted R squared 0.39); among "frail" participants the associations were with depressive status and younger age, and among "robust" participants the association was with lower body mass index.Conclusions: Five out of seven dimensions of QOL were negatively affected by frailty, but only one SOF criterion for frailty was independently related to QOL, after correction for age, functional status and depression. A more advanced age as well as a better affective status were correlates of a better QOL among frail elders. Interventions targeting the QOL in frail community-dwelling older outpatients should consider as outcomes, not only health-related QOL, but also other domains of the QOL.
