To determine the prevalence of self-reported lower extremity pain and the impact on functionality and quality of life in a population based study of elderly women in Western Australia.
One thousand four hundred eighty-six women, 6.2% of 24,800 women aged over 70 in Perth, were recruited. An index of relative socioeconomic disadvantage (SES) was derived from postcode. Self-reported lower extremity pain at the hip, knee, and foot was collected by questionnaire. The frequency of lower extremity pain was classified into 5 groups. Mobility was measured by the Timed Up and Go Test (TUG). Quality of life was measured using the Medical Outcome Study Short Form 36 (SF-36) summary statistics: physical and mental component scores (PCS and MCS).
The prevalence of women reporting any hip, knee, and foot pain was 39%, 52%, and 34% respectively. Fourteen percent experienced pain at all sites whereas 28% had no pain. There was no age difference between the various pain groups. Women with more pain were heavier and had higher BMI scores. At all lower limb sites, women with more frequent pain had reduced mobility and lower quality of life as measured by TUG, PCS, and MCS. For the TUG test, significant determinants in stepwise regression were age, BMI, knee and hip pain. For the SF-36 PCS, significant predictors were age, SES, BMI, and foot, knee, and hip pain. For the SF-36 MCS, SES and foot pain were significant predictors.
Our results confirm the high prevalence of lower extremity pain in elderly women in Australia. Lower extremity pain significantly reduced both physical and mental aspects of the quality of life as well as mobility. In view of the availability of effective interventions to reduce joint pain, more aggressive intervention in the most disabled is indicated.
在西澳大利亚州针对老年女性开展的一项基于人群的研究中，确定自我报告的下肢疼痛患病率及其对功能和生活质量的影响。
招募了1486名女性，占珀斯24800名70岁以上女性的6.2%。相对社会经济劣势（SES）指数由邮政编码得出。通过问卷调查收集自我报告的髋部、膝部和足部的下肢疼痛情况。下肢疼痛频率分为5组。采用定时起立行走测试（TUG）测量活动能力。使用医学结局研究简明健康调查问卷36项（SF-36）汇总统计数据测量生活质量：身体和心理成分得分（PCS和MCS）。
报告有髋部、膝部和足部疼痛的女性患病率分别为39%、52%和34%。14%的女性在所有部位都有疼痛，而28%的女性没有疼痛。不同疼痛组之间不存在年龄差异。疼痛较多的女性体重更重，BMI得分更高。在所有下肢部位，疼痛频率较高的女性，通过TUG、PCS和MCS测量，其活动能力下降，生活质量较低。对于TUG测试，逐步回归中的显著决定因素是年龄、BMI、膝部和髋部疼痛。对于SF-36 PCS，显著预测因素是年龄、SES、BMI以及足部、膝部和髋部疼痛。对于SF-36 MCS，SES和足部疼痛是显著预测因素。
我们的结果证实了澳大利亚老年女性下肢疼痛的高患病率。下肢疼痛显著降低了生活质量的身体和心理方面以及活动能力。鉴于有有效的干预措施可减轻关节疼痛，表明应对最残疾的人群进行更积极的干预。
