调查水果和蔬菜摄入量（FVI）和身体活动（PA）的不同维度作为残疾变化和其他已知的进行性残疾前兆的预测因子，在基于人群的非裔美国人样本中进行FVI和PA与6年残疾变化和其他已知的进行性残疾前兆的独立关联的纵向调查。在第8波（2008年）期间，使用2005年行为风险因素监测系统问题和使用耶鲁体育活动调查（YPAS）的PA维度测量FVI。残疾测量包括基本日常生活活动（ADL）和工具性ADL（IADL）;其他前兆包括测量的步态速度、握力和短体能测试（SPPB）以及报告的下肢功能限制（LBFL）和FRAIL量表;这些在第4波（2004年）和第10波（2010年）测量。残差变化评分线性回归用于识别FVI和PA因素，这些因素与残疾和其他前兆的6年变化独立相关。纵向上，悠闲散步与更好的ADL、IADL、握力、SPPB、LBFL和虚弱结局独立相关;站立与更好的IADL和SPPB独立相关;摄入胡萝卜、沙拉或土豆以外的蔬菜与更好的握力和虚弱结局独立相关;摄入果汁与更差的握力和虚弱结局独立相关。除了土豆摄入量之外，蔬菜也有好处，果汁摄入量与有害影响有关。这项研究强调了寻找策略来帮助这一人群增加PA（特别是悠闲散步）和整个水果和蔬菜摄入量的重要性。
To investigate fruit and vegetable intake (FVI) and different dimensions of physical activity (PA) as predictors of change in disabilities and other known precursors of progressive disability in a populationbased sample of African Americans.Longitudinal investigation of the independent associations of reported FVI and PA with six-year changes in disabilities and other known precursors of progressive disability.Longitudinal study of a population-representative cohort of late middle-aged African Americans.432 cohort participants with complete information on all measures.During wave 8 (2008), FVI was measured using 2005 Behavioral Risk Factor Surveillance System questions and PA dimensions using the Yale Physical Activity Survey (YPAS). Disability measures included basic activities of daily living (ADLs) and instrumental ADLs (IADLs); other precursors included measured gait speed, grip strength, and short physical performance battery (SPPB) and reported lower body functional limitations (LBFLs) and FRAIL scale; these were measured at wave 4 (2004) and wave 10 (2010). Residualchange score linear regression was used to identify FVI and PA factors that were independently associated with six-year changes in disability and other precursors.The study cohort was less active than the YPASdevelopment group. Longitudinally, leisurely walking was independently associated with better ADL, IADL, grip strength, SPPB, LBFL, and frailty outcomes; standing with better IADL and SPPB; intake of vegetables other than carrots, salads, or potatoes with better grip strength and frailty; and fruit juice intake with worse grip strength and frailty.In this relatively inactive cohort, leisurely walking was associated with multiple beneficial outcomes. Benefits were also seen with vegetables other than potato intake, and fruit juice intake was associated with detrimental effects. This study highlights the importance of finding strategies to help this population increase PA (especially leisurely walking) and intake of whole fruits and vegetables.
