While urban built environments might promote active ageing, an infrequently studied question is how the neighbourhood walkability modulates physical activity changes during a intervention programme in older adults. We assessed influence of objectively on change used ongoing PREvención con DIeta MEDiterránea (PREDIMED)-Plus trial.The present study involved 228 PREDIMED-Plus senior participants aged between 55 and 75, recruited Palma de Mallorca (Spain). Overweight/obese adults with metabolic syndrome were randomised to intensive weight-loss lifestyle or control group. A index (residential density, land use mix, intersections density) was calculated using geographic information systems (1 km sausage-network buffer). Physical accelerometer validated questionnaire, at baseline two follow-up visits (6-months 1-year later). Generalised additive mixed models fitted estimate association follow-up.Higher z-score increment) associated moderate-to-vigorous duration, (β = 3.44; 95% CI 0.52; 6.36 min/day). When analyses stratified by arm, only observed group 6.357; 2.07;10.64 min/day) (P for interaction 0.055).The results indicate that could support intervention, helping maintain increase adults' activity.
