Association between activity space exposure to food establishments and individual risk of overweight.

<h4>Objective</h4>Environmental exposure to food sources may underpin area level differences in individual risk for overweight. Place of residence is generally used to assess neighbourhood exposure. Yet, because people are mobile, multiple exposures should be accounted for to assess the...
