Interventions on Diet and Physical Activity: What Works
Implementation of the Global Strategy on Diet, Physical Activity and Health
"Interventions on diet and physical activity: what works" (What Works) provides policy-makers and other stakeholders with a summary of tried and tested diet and physical activity interventions that aim to reduce the risk of chronic noncommunicable diseases (NCD).
"What Works" is presented as three complementary documents (one summary report and two background documents):
The "Summary Report" provides relevant stakeholders with a summary of the systematic review of evidence evaluating the effectiveness of diet and physical activity interventions to prevent chronic NCD.
In the "Summary Report" the evidence collected is presented in eight categories. Although this categorization was chosen to facilitate the analysis and presentation of results, it should be highlighted that for interventions to be effective they should be integrated and consistent with a broad supportive policy.
A synopsis of the information included in each of these categories, as well as the whole document, can be accessed through the links below:

- Mass media
- Community-based interventions
- Primary health care
- Older adults
- Religious settings
The background paper "Methodology", provides researchers and other interested parties with detailed information on the five stages of the methodology used for the review.
The methodology used for What Works was designed to evaluate the existing evidence on the effectiveness of diet and physical activity interventions that aim to prevent chronic NCD at group, community and population levels, with a focus on disadvantaged communities and low- and middle-income countries.
The background paper "Evidence tables", provides researchers and other interested parties the detailed results of the review of the evidence evaluating the effectiveness of intervention studies included in the systematic review.
