Table 6 Summary of findings table for comparison 1.2: Active transport interventions

From: Infrastructure, policy and regulatory interventions to increase physical activity to prevent cardiovascular diseases and diabetes: a systematic review

Patient or population: Children and adults, both living in the community as well as those travelling to and from school and work, respectively

Setting: Communities and neighbourhoods in HICs

Intervention: Creating or upgrading sidewalks, crosswalks, walking, cycling and running paths, light rail routes (e.g. street cars, trams), improvement of the near-school cycling and walking environment, or a motorway

Comparison: no new intervention

Impact

Physical activity

assessed with: proportion/time cycling, biking, walking, MVPA, transit related active trips

follow-up: 1 year to 10 years

16 CBA studies, 1 ITS

      

VERY LOW a, b

Seven studies reported a clear effect favouring the intervention, six studies reported an unclear effect potentially favouring the intervention, three studies reported an unclear effect potentially favouring the control, and one study reported a clear effect favouring the control

Body weight

assessed with: BMI

follow up: 12 months

2 CBA studies

One study observed a clear effect favouring the intervention and one study observed an unclear effect potentially favouring the control

  1. CI Confidence interval, HICs high-income countries, RR Risk ratio, OR Odds ratio, MVPA moderate to vigorous physical activity, CBA controlled before-after
  2. Explanation
  3. aDowngraded by 1 for risk of bias: high risk across several domains in multiple studies; there is high potential for direction of effect to change
  4. bDowngraded by 1 for imprecision: very wide confidence intervals in most studies
