Residential Surrounding Greenness and Cognitive Decline: A 10-Year Follow-up of the Whitehall II Cohort.

ABSTRACT:

Background

Evidence on beneficial associations of green space with cognitive function in older adults is very scarce and mainly limited to cross-sectional studies.

Objectives

We aimed to investigate the association between long-term residential surrounding greenness and cognitive decline.

Methods

This longitudinal study was based on three waves of data from the Whitehall II cohort, providing a 10-y follow-up (1997-1999 to 2007-2009) of 6,506 participants (45-68 y old) from the United Kingdom.
