目的：确定积极情感是否对老年墨西哥裔美国人的功能状态、活动性和生存率有独立影响。设计：2年前瞻性队列研究。地点：西南部5个州：德克萨斯州、加州州、亚利桑那州、新墨西哥州和科罗拉多州。参与者：2282名墨西哥裔美国人，年龄65至99岁，基线访谈时报告无功能限制。测量：1993-1994年和1995-1996年的家庭访谈评估了人口统计学变量、健康状况、日常生活活动、基于绩效的移动性、生存率以及积极和消极影响的评级。在多变量分析中，基线时的积极情感评分与2年后的活动性、功能状态和生存率有直接关系，控制功能状态、社会人口学变量、主要慢性病、体重指数（BMI）、吸烟状态、饮酒状态和基线时的负面影响。积极情绪高的人（比值比（OR）= 0.48; 95%置信区间（CI）0.29，0.93）在日常生活活动（ADL）中成为残疾的可能性为三分之二（OR = 0.64; 95% CI 0.51，0.79）步行速度缓慢，（OR 0.53; 95%CI 0.30，0.93）与积极情感评分较低的患者相比，在2年随访期间死亡。我们的研究结果支持了这样一个概念，即积极的情感或情绪健康不同于没有抑郁或消极的情感。积极的情感似乎可以保护个人在老年时身体不衰退。
OBJECTIVE: To determine whether positive affect has an independent effect on functional status, mobility, and survival in an older Mexican American sample.DESIGN: A 2-year prospective cohort study.SETTING: Five Southwestern states: Texas, California, Arizona, New Mexico, and Colorado.PARTICPANTS: A population-based sample of 2282 Mexican Americans aged 65 to 99 who reported no functional limitations at baseline interview.MEASUREMENTS: In-home interviews in 1993-1994 and again in 1995-1996 assessed demographic variables, health conditions, activities of daily living, performance-based mobility, survival, and a rating of positive and negative affect.RESULTS: In multivariate analyses, there was a direct relationship between positive affect scores at baseline and mobility, functional status, and survival 2 years later, controlling for functional status, sociodemographic variables, major chronic conditions, body mass index (BMI), smoking status, drinking status, and negative affect at baseline. Subjects with high positive affect were half as likely (odds ratio (OR) = 0.48; 95% confidence interval (CI) 0.29, 0.93) to become disabled in activities of daily living (ADLs), two-thirds as likely (OR = 0.64; 95% CI 0.51, 0.79) to have a slow walking speed, and half as likely (OR 0.53; 95% CI 0.30, 0.93) to have died during the 2-year follow-up compared to those with lower positive affect scores.CONCLUSIONS: Our results support the concept that positive affect, or emotional well-being, is different from the absence of depression or negative affect. Positive affect seems to protect individuals against physical declines in old age.
