- Abstract
Walking may be impeded by environmental factors. We assessed the association between walking and neighbourhood characteristics among the first 39 adults with type 2 diabetes evaluated as part of a cohort study. Assessment included pedometer monitoring (2 weeks) and 8 questions derived from environment surveys (sidewalk condition, lighting, traffic, nearby stores, nearby transit stop, interesting sights, neighbours' activity, safety). Categories for each item were coded (1 to 4 for 7 items; 1 to 5 for 1 item) and summed for a "neighbourhood score" (8 most favourable; 33 least favourable). We examined the relationship between walking (steps/day) and neighbourhood score through a sex-adjusted linear regression model and selected between age vs. diabetes duration and between BMI vs. waist circumference as other potential determinants. Participants were obese (mean BMI31.5 kg/m², SD 6.3) and middle-aged to elderly (mean age 62 years, SD 11), with men and women equally represented. Mean A1C (8.0%, SD 1.8) was above current recommendations and average walking (mean 4,713 steps/day, SD 2,567) at sedentary levels (< 5,000 steps/day). In a linear regression model, a one-point neighbourhood score increase (i.e. less favourable) was associated with 245 fewer steps/day (95% CI82 to 409). A one-year age increment was associated with an 80-step reduction (12 to 147). A one-cm waist circumference increment was associated with a 73 step reduction (19 to 127). Although men were estimated to walk 773 steps/day more than women, a wide confidence interval (660 steps less to 2207 steps more) precludes strong conclusions. Neighbourhood characteristics favouring walking were associated with increased walking levels among middle-aged to older adults with type 2 diabetes. With further recruitment, we anticipate that we will have sufficient sample size for accurate estimation of other potential confounding variables (e.g. educational level), to ascertain whether the association between neighbourhood characteristics and walking remains important.
