OBJECTIVES
There are few data on the relationship between health-related quality of life (HRQoL) and physical activity among elderly individuals with pre-diabetes. This study aimed to determine if differences existed in HRQoL between individuals with pre-diabetes who were physically active compared with those who were physically inactive in rural China.
DESIGN, SETTING AND PARTICIPANTS: A cross-sectional survey was conducted among the elderly (≧60 years) in rural communities in Yiyang City of China. Multistage cluster random sampling was carried out to select 42 areas, and interviews were conducted among 434 elderly individuals with pre-diabetes. Pre-diabetes was screened using an oral glucose tolerance test.
MAIN OUTCOME MEASURES
The Medical Outcomes Study 36-Item Short Form Health Survey questionnaire was used to measure HRQoL. Physical activity was assessed using the International Physical Activity Questionnaire. Multivariate analysis of covariance (MANCOVA) was used to test for differences in HRQoL between the physically active group and the inactive group.
RESULTS
A total of 434 individuals with pre-diabetes were included in this study. The physical component summary (PCS) score of HRQoL was 42.1±10.2 and the mental component summary score was 46.4±8.9. A median total physical activity of 524 metabolic equivalent-min/week was reported. A significant MANCOVA model (Wilks' λ=0.962, (2,423)=8.44, P<0.001) indicated that elderly individuals with pre-diabetes who were physically active reported higher PCS scores (M=5.2, P<0.001, effective size=0.47) compared with those physically inactive after adjusting for the following covariates: age, gender, marital status, education, smoking, chronic disease, body mass index and waist:hip ratio.
CONCLUSIONS
The HRQoL of elderly individuals with pre-diabetes is poor in rural China. These findings demonstrated that elderly individuals with pre-diabetes who were physically active had higher PCS scores than those who were physically inactive. Furthermore, these results support the rationale for developing a physical activity intervention for HRQoL of individuals with pre-diabetes.

目的
关于糖尿病前期老年个体的健康相关生活质量（HRQoL）与身体活动之间的关系，数据较少。本研究旨在确定在中国农村，身体活动的糖尿病前期个体与身体不活动的个体在HRQoL方面是否存在差异。
设计、背景与参与者：在中国益阳市农村社区对老年人（≧60岁）进行了一项横断面调查。采用多阶段整群随机抽样选取42个地区，并对434名糖尿病前期老年个体进行访谈。通过口服葡萄糖耐量试验筛查糖尿病前期。
主要观察指标
使用医学结局研究36项简短健康调查问卷来测量HRQoL。使用国际身体活动问卷评估身体活动情况。采用多变量协方差分析（MANCOVA）来检验身体活动组和不活动组在HRQoL方面的差异。
结果
本研究共纳入434名糖尿病前期个体。HRQoL的身体成分汇总（PCS）评分为42.1±10.2，心理成分汇总评分为46.4±8.9。报告的每周总身体活动中位数为524代谢当量分钟。一个显著的MANCOVA模型（威尔克斯'λ=0.962，(2,423)=8.44，P<0.001）表明，在调整了以下协变量后：年龄、性别、婚姻状况、教育程度、吸烟、慢性病、体重指数和腰臀比，身体活动的糖尿病前期老年个体的PCS评分（M=5.2，P<0.001，效应量=0.47）高于身体不活动的个体。
结论
在中国农村，糖尿病前期老年个体的HRQoL较差。这些发现表明，身体活动的糖尿病前期老年个体的PCS评分高于身体不活动的个体。此外，这些结果支持了为糖尿病前期个体的HRQoL开展身体活动干预的理论依据。
