6-Year Study of Seniors. Neighborhood Environments, Physical Activity & Function Built environment changes have been recommended by the IOM, CDC, and others to improve physical activity (PA). Such changes may be most important for vulnerable groups like older adults who are least active and least studied. Scientists consistently call for prospective studies of built environment and PA. The proposed study is a 6-year follow-up of the Senior Neighborhood Quality of Life Study (SNQLS) cohort of 66+ year-old residents of neighborhoods selected to maximize variability in walk ability and income. Analyses of current data show neighborhood environments are related to PA and BMI. SNQLS is more methodologically advanced than other studies, with objective and perceived measures of both environments and PA, and a prospective follow-up can strengthen evidence of causality. A key innovation is re-assessment of the full range of PA-related environmental characteristics, including walk ability (GIS measured mixed use & street connectivity), microscale features (systematically observed and self-reported streetscape details such as sidewalk quality, safety of street crossings), and access to senior-relevant recreation facilities (GIS and reported). In addition to repeating accelerometer measures, we will add GPS assessment of mobility within neighborhoods. Aim 1, guided by ecological models, is to explain patterns of change in PA from 7-day accelerometry over 6 years by comprehensive measures of neighborhood environments and psychosocial variables. Secondary aims will assess moderators (eg, physical function) of the relationship of 6-year change in PA with environmental measures and environmental correlates of 6-year changes in a validated measure of physical function, walking for transport and recreation, BMI, and sedentary time. Exploratory aims will assess the impact of changing residences and examine correlates of GPS-measured mobility and its health consequences. Based on pilot data, we expect to measure 70% (projected follow-up N=603) of the sample who participated at Time 1. The study will fill many gaps in knowledge about the relation of environments to multiple health outcomes in seniors. The interdisciplinary team will use results to advance the science of environments and health and develop evidence-based guidelines for designing neighborhoods that support healthy aging.

老年人的6年研究。 IOM，CDC和其他人建议改善体育锻炼（PA），邻里环境，体育活动和功能建立环境变化。这种变化对于弱势群体（例如最不活跃且研究最少的老年人）可能是最重要的。科学家始终呼吁对建筑环境和PA进行前瞻性研究。拟议的研究是对高级邻里生活质量研究（SNQLS）队列的6年随访，该研究被选为66岁以上的居民，以最大程度地提高步行能力和收入的变异性。当前数据的分析表明，邻里环境与PA和BMI有关。 SNQL比其他研究更为先进，具有对环境和PA的客观和感知度量，并且前瞻性随访可以增强因果关系的证据。一个关键的创新是重新评估与PA相关的环境特征的全部范围，包括步行能力（GIS测量的混合用途和街道连接），显微镜特征（系统观察到和自我报告的街道景观细节，例如人行道质量，街道交叉安全性），以及与高级娱乐设施的访问（GIS和GIS和报告）。除了重复加速度计测量外，我们还将添加社区内移动性的GPS评估。 AIM 1在生态模型的指导下是通过对邻里环境和社会心理变量的全面度量来解释PA的变化模式，从7天的加速度计来解释6年的加速度计。次要目的将评估PA变化6年变化与环境措施和环境相关性的主持人（例如身体机能），以验证的身体机能，步行，用于运输和娱乐，BMI和久坐时间的衡量标准。探索目的将评估不断变化的住所的影响，并检查GPS测量的流动性及其健康后果的相关性。根据试点数据，我们预计参与时间1的样本中的70％（预计的随访n = 603）。该研究将填补有关环境与老年人多种健康结果的知识的许多缺口。跨学科团队将使用结果来推进环境和健康科学，并制定基于证据的指南，以设计支持健康衰老的社区。
