Promoting physical activity in low-income African-American communities: the PARR project

Area of Science:

• Public Health
• Community Health Interventions
• Health Disparities

Background:

• Low-income and minority populations often exhibit lower physical activity levels compared to the general population.
• Addressing physical activity disparities is crucial for improving overall health outcomes in underserved communities.

Purpose of the Study:

• To implement and evaluate a constituency-based physical activity promotion program, the Physical Activity for Risk Reduction (PARR) project.
• To identify barriers and facilitators to physical activity in residents of public housing communities.
• To assess the effectiveness of community-led interventions in increasing physical activity.

Main Methods:

• A community-based participatory research approach was used, involving trained community residents in data collection and intervention delivery.
• Focus groups and surveys were employed to gather data on exercise practices, beliefs, barriers, and facilitators.
• A quasi-experimental design with six intervention and two control communities was utilized for program evaluation.

Main Results:

• The baseline survey indicated that 31% of respondents, predominantly African Americans, reported no physical activity in the previous year.
• Significant variability in attendance at group exercise sessions was observed across communities (P < .05).
• This variability in intervention effectiveness was linked to community and leader-related factors, influencing changes in physical activity levels.

Conclusions:

• Community-based physical activity interventions can be implemented in underserved areas.
• Intervention effectiveness is influenced by community-specific factors and leadership.
• Findings from the PARR project offer valuable insights for designing and delivering health programs in similar populations.
