Methods for accounting for neighbourhood self-selection in physical activity and dietary behaviour research: a systematic review

Abstract

BACKGROUND: Self-selection into residential neighbourhoods is a widely acknowledged, but under-studied problem in research investigating neighbourhood influences on physical activity and diet. Failure to handle neighbourhood self-selection can lead to biased estimates of the association between the neighbourhood environment and behaviour.
