目的：很少有研究调查吸烟和认知能力下降（CD）的老年墨西哥裔美国人。在这项研究中，作者探讨了吸烟状况与墨西哥裔社区老年人随时间变化的关系。设计图：潜在增长曲线分析被用来检查随着年龄的增长（7岁，4个数据收集点）的认知功能测试的正确反应的数量的减少增长。设置：在家庭访谈中获得的参与者居住在美国西南部。参与者：参与者是居住在社区的墨西哥裔美国人。测量：在四个数据收集点的每一个用简易精神状态检查评估认知功能。参与者的健康功能和吸烟状况的自我报告在基线时获得。结果如下：随着健康变量和其他控制变量的纳入，吸烟状态对认知功能的影响是显着的，随着时间的推移，吸烟者的正确反应数量的减少大于非吸烟者。结论：吸烟增加社区居住的墨西哥裔美国老年人患CD的风险。戒烟对健康有许多好处，即使是吸烟多年的老年人也是如此。进一步努力，以确保戒烟和预防计划是针对西班牙裔是必要的。(Am J Geriatr Psychiatry 2009; 17：934-942）
Objectives: Few studies have investigated smoking and cognitive decline (CD) among older Mexican Americans. In this study, the authors explore the relationship between smoking status and cognitive changes over time in a large sample of community-dwelling older adults of Mexican descent. Design: Latent growth curve analyses were used to examine the decreasing growth in the number of correct responses on a test of cognitive functioning with increasing age (7 years with four data collection points). Setting: In-home interviews were obtained from participants residing in the Southwest United States. Participants: Participants were community-dwelling older Mexican Americans. Measurements: Cognitive functioning was assessed at each of the four data collection points with the Mini-Mental State Examination. Participants' self-reports of health functioning and smoking status were obtained at baseline. Results: With the inclusion of health variables and other control variables, the effect of smoking status on cognitive functioning was significant such that the decrease in the number of correct responses over time was greater for smokers than for nonsmokers. Conclusions: Smoking increases risk for CD among community-dwelling older Mexican Americans. There are numerous health benefits in quitting smoking, even for older adults who have been smoking for many years. Further efforts to ensure that smoking cessation and prevention programs are targeted toward Hispanics are necessary. (Am J Geriatr Psychiatry 2009; 17:934-942)
