Local-scale deprivation is associated with the spatial distribution of poor diet quality in adults: A cross-sectional population-based study in Switzerland

Poor diet quality is linked to non-communicable diseases and mortality. Area deprivation is an important determinant of diet. Whether small area deprivation influences the spatial distribution of diet quality remains unknown. We aimed to assess the spatial ...
