The Health Assessment Questionnaire (HAQ) disability index (DI) has been commonly used in rheumatology to quantify functional disability in patient groups, but current general population values of this index are not available. This study was undertaken to establish normative values for the HAQ DI in a general population and to analyze its correlates.
The HAQ DI (range of scores 0-3) was measured in a random sample of 1,530 adults in the Central Finland District. Prevalence rates of disability by strata of age, sex, education level, body mass index (BMI), and health behaviors (including smoking and exercise habits) were calculated. Pearson's product-moment correlation coefficient and ordinary least squares regression were used to analyze the data.
The estimated population mean HAQ DI was 0.25 (95% confidence interval 0.22-0.28), and 32% of respondents had at least some disability. Both for men and for women, functional disability increased exponentially with age. The HAQ DI was correlated with pain (r = 0.58) and global self assessment (r = 0.61). The prevalence of disability decreased with increasing number of years of education, lower BMI, and increasing frequency of physical exercise.
Almost one-third of the general population has some functional disability. Functional disability is associated in part with lifestyle choices and increases with age in a nonlinear manner. The normative values of the HAQ DI that we have presented could be used as a reference benchmark for clinical and epidemiologic studies using this measure of disability.
健康评估问卷（HAQ）残疾指数（DI）在风湿病学中常用于量化患者群体的功能残疾情况，但目前该指数在普通人群中的数值尚无可用数据。本研究旨在确定普通人群中HAQ DI的标准值并分析其相关因素。
对芬兰中部地区1530名成年人的随机样本测量了HAQ DI（得分范围0 - 3）。计算了按年龄、性别、教育水平、体重指数（BMI）和健康行为（包括吸烟和运动习惯）分层的残疾患病率。使用Pearson积矩相关系数和普通最小二乘法回归分析数据。
估计的总体平均HAQ DI为0.25（95%置信区间0.22 - 0.28），32%的受访者至少有某种程度的残疾。男性和女性的功能残疾均随年龄呈指数增长。HAQ DI与疼痛（r = 0.58）和整体自我评估（r = 0.61）相关。残疾患病率随受教育年限增加、BMI降低和体育锻炼频率增加而降低。
近三分之一的普通人群存在某种功能残疾。功能残疾部分与生活方式选择有关，并以非线性方式随年龄增加。我们给出的HAQ DI标准值可作为使用该残疾测量方法的临床和流行病学研究的参考基准。
