“…The most common environmental exposures were green space and/or blue space (water) (30%) [ 35 , 41 , 46 – 48 , 51 , 53 , 57 , 60 , 61 , 63 ], neighborhood socioeconomic status (SES) (25%) [ 30 , 31 , 33 , 37 , 42 , 44 , 52 , 54 , 55 , 62 ] and recreation/physical activity facilities (20%) ( Figure 2 ) [ 6 , 25 , 29 , 42 , 49 , 50 , 57 ]. Most studies (65%) only provided environmental exposure measures at one timepoint ( Table 1 ) [ 6 , 25 – 27 , 29 , 31 – 35 , 37 , 38 , 40 – 45 , 53 – 55 , 57 – 59 , 61 , 62 ]. Over half of the papers (70%) examined cognitive function or cognitive decline [ 6 , 25 – 29 , 31 , 32 , 34 , 36 – 38 , 40 , 42 – 51 , 53 , 55 , 56 , 58 , 60 , 62 ], often through global cognitive score (60%) [ 6 , 25 – 29 , 35 ...…”
