Physically-active and sedentary behaviors are determinants of adult weight gain and are associated with built-environment attributes. We reviewed recent evidence on built-environment attributes with adult adiposity. Of 41 relevant papers identified, 34 reported cross-sectional, six recorded prospective findings, and one included both cross-sectional and prospective designs. In 15 cross-sectional examinations of composite built environment indices (walkability; composite other), seven identified significant positive relationships in the expected direction; of 42 instances examining particular walkability elements (density, connectivity, land use mix), 13 were positive. Of 44 instances examining proximity of utilitarian and recreational destinations, there were 13 positive associations; and, of 41 instances examining pedestrian-environment attributes, 12 were positive. In the seven prospective studies, 20 sets of relationships were identified – nine were significant and in the expected direction. Evidence on built environment/adiposity relationships remains modest and could be strengthened through improvements in measurement methods and with further evidence from prospective studies.
