Neighbourhood walkability and home neighbourhood-based physical activity: an observational study of adults with type 2 diabetes

Table 3 Regression estimates for the full-adjusted neighbourhood-based total VeDBA model with corresponding changes in daily steps (n = 97)^a

	Percent change in one SD of total VeDBA (95 % confidence intervals)^b	Corresponding change in daily steps (95 % confidence intervals)^c
Age, years	−0.01 (−0.9 to 0.8)	−0.1 (−14 to 14)
Women	−8.5 (−26.5 to 9.4)	−135 (−421 to 150)
Body mass index, kg/m²	−1.2 (−3.2 to 0.9)	−19 (−51 to 14)
University educated (yes versus no)	−8.8 (−26.8 to 9.1)	−140 (−425 to 144)
Spring/summer assessment (versus fall/winter)	16.1 (−1.2 to 33.4)	256 (−19 to 531)
Regular car access (yes versus no)	−38.6 (−59.3 to −17.9)	−613 (−942 to −284)
Residential self-selection score	5.3 (−4.5 to 15.1)	84 (−72 to 240)
Valid wear-time, minutes	0.01 (−0.002 to 0.01)	0.1 (−0.03 to 0.2)

^aThis fully adjusted model is additionally adjusted for GIS-derived neighbourhood walkability
^bEffect estimates represent the percent change in one standard deviation of total VeDBA occurring in home neighbourhoods (excluding homes) for every one-unit increase in the predictor of interest. Calculated by dividing the original beta estimate by the standard deviation of VeDBA (occurring within home neighbourhoods but excluding homes) (i.e., 39,149.22) and multiplying by 100
^cCalculated using the following formula: daily steps = −548 + 0.0089*total VeDBA occurring anywhere)*(% change in one SD of VeDBA occurring in neighbourhood/100) where VeDBA occurring anywhere equals one SD of VeDBA occurring anywhere (i.e., 240,065.36)
