“Diet & Food Policy Changes
Changes with strong impacts were ones that improved the nutritional quality of foods:
- Trans-fat bans
- Sugary food and beverage availability limits
- Higher-fat food availability limits
Changes that had smaller or no impacts in the research to date included:
- Nutritional information requirements
- Supermarkets built in underserved areas
Physical Activity Focused Changes
Changes with stronger impacts included:
- Active transportation infrastructure improvements
- Changes studied after longer-term follow-up periods
More research is needed to look at physical activity effects (not just use of amenities) for built environment changes including:
- Park improvements
- Trails
- Active transportation infrastructure
The researchers noted that a common shortcoming in many studies is that they only measured process outcomes such as food purchases or use of bike/transit infrastructure, rather than measuring the desired health outcomes, such as weight loss.”
