Mass media campaigns can provide physical activity messages to large and broad audiences using television, social media, radio, billboards, and newspapers and other print media. These campaigns aim to increase knowledge, influence attitudes and beliefs, and change behavior1.
Expected Beneficial Outcomes (Rated)
Increased physical activity
Improved physical fitness
Other Potential Beneficial Outcomes
Improved weight status
Evidence of Effectiveness
There is insufficient evidence to determine whether mass media campaigns promoting physical activity increase physical activity and improve physical fitness1, 2. Available evidence suggests that mass media campaigns may raise awareness and increase motivation to prevent weight gain3, 4. However, additional evidence is necessary to determine effects.
Most mass media campaigns for physical activity appear to provide equitable or better effects for those with low incomes compared to those with higher incomes, though results are inconsistent and tailoring is needed to ensure programs are most effective for those with low incomes5. Comprehensive obesity prevention campaigns that include both physical activity and nutrition components can influence knowledge and attitudes more than campaigns only addressing physical activity; although additional evidence is needed to confirm effects on behavior and long-term outcomes6. One comprehensive media documentary campaign, Weight of the Nation, appears to increase obesity awareness and may influence short-term healthy behavior intentions7.
Media campaigns can be implemented at relatively low cost8 and can be more effective when combined with behavioral interventions9. Experts suggest integrating campaigns to increase physical activity with broader obesity campaigns; pre-testing campaign materials; including a focus on social and environmental causes of obesity rather than personal behaviors; and using social media and other media outlets beyond television6. Tailoring can include culturally-adapted campaign materials, in the preferred or first language of the intended audience, and use of appropriate media channels10.
Experts suggest that general media coverage of childhood obesity, such as parenting magazines, should also reframe the issue as an environmental problem requiring broad policy solutions, rather than focusing only on parental actions11.
Impact on Disparities
North Carolina’s 12 and California’s 13 are examples of state-sponsored mass media interventions to promote obesity prevention. The 14 campaign produced by HBO and the Institute of Medicine (IOM) is an example of a privately supported campaign. This campaign includes a four-part documentary series and a web-based tool.
Mass in Motion (MiM) is a statewide comprehensive obesity prevention intervention that includes several components, including a mass media campaign. Components have also included the Massachusetts’ Childhood Obesity Research Demonstration (CORD) Project and its media competition for elementary and middle school students to design art, videos, and music promoting program goals, such as increasing physical activity15, 16.
