To examine the independent impact of common medical conditions on lower-extremity function in Mexican-American elderly.
Cross-sectional study using a probability sample of non-institutionalized Mexican Americans aged 65 or older.
The five Southwestern states, Texas, New Mexico, Arizona, Colorado and California.
All subjects were interviewed in person (n = 2,873) or by proxy (n = 177) in their homes during late 1993 and early 1994.
Respondents were asked whether they could perform four activities related to lower-extremity function without help: walking across a small room, getting from a bed to a chair, walking up and down stairs, and walking half a mile. A summary measure of lower body disability created from these four items was regressed on seven common medical conditions plus five control variables using multiple logistic regression.
Adjusted Odds Ratios (OR) suggested that impaired lower-extremity function was associated with previous diagnosis of hip fracture (OR = 4.28), stroke (OR = 3.47), lower extremity arthritis (OR = 2.60), heart attack (OR = 2.29), diabetes (OR = 2.03) and obesity (OR = 1.50). Impaired lower-extremity function was significantly associated with older age (75+ years old), gender (female) and marital status (unmarried). In addition, there was a linear increase in the risk of function loss by number of medical conditions.
It appears that Mexican-American elderly diagnosed with medical conditions, especially stroke and hip fracture, have a high risk for lower-extremity dysfunction. These findings have implications for efforts to prevent or reduce lower-extremity dysfunction, as well as for the provision of community-based long-term care services for Mexican-American elderly.
研究常见疾病对墨西哥裔美国老年人下肢功能的独立影响。
采用横断面研究，对65岁及以上非机构化墨西哥裔美国人进行概率抽样。
德克萨斯州、新墨西哥州、亚利桑那州、科罗拉多州和加利福尼亚州这五个西南部州。
1993年末至1994年初，所有受试者均在家中接受了当面访谈（n = 2,873）或由他人代答（n = 177）。
询问受访者是否能够在无需帮助的情况下完成四项与下肢功能相关的活动：穿过一个小房间、从床上坐到椅子上、上下楼梯以及步行半英里。利用这四个项目创建了一个下肢残疾综合指标，并通过多元逻辑回归分析该指标与七种常见疾病以及五个控制变量之间的关系。
调整后的优势比（OR）表明，下肢功能受损与既往髋部骨折诊断（OR = 4.28）、中风（OR = 3.47）、下肢关节炎（OR = 2.60）、心脏病发作（OR = 2.29）、糖尿病（OR = 2.03）和肥胖（OR = 1.50）相关。下肢功能受损与高龄（75岁及以上）、性别（女性）和婚姻状况（未婚）显著相关。此外，功能丧失风险随疾病数量呈线性增加。
似乎被诊断患有疾病，尤其是中风和髋部骨折的墨西哥裔美国老年人，下肢功能障碍风险较高。这些发现对于预防或减少下肢功能障碍的努力以及为墨西哥裔美国老年人提供社区长期护理服务具有启示意义。
