Changes in Physical Activity Barriers among American Indian Elders: A Pilot Study​.

Area of Science:

• Gerontology
• Public Health
• Exercise Science

Background:

• Physical activity is crucial for elder health.
• American Indian elders face unique barriers to physical activity.
• Understanding and reducing these barriers is essential for health promotion.

Purpose of the Study:

• To evaluate if self-reported physical activity barriers decrease in American Indian elders after a 6-week randomized trial.
• To compare pedometer-only use versus pedometers with step-count goal setting.
• To identify differences between high- and low-barrier groups.

Main Methods:

• A 6-week pilot randomized physical activity trial with 32 American Indian elders.
• Used the Barriers to Being Physically Active Quiz at baseline and post-intervention.
• Compared groups on physical activity, quality of life, step counts, and 6-minute walk performance.

Main Results:

• Only the 'lack of willpower' barrier significantly decreased post-intervention.
• The low-barrier group showed higher physical activity engagement and improved mental health quality of life.
• No significant differences were found in daily step counts or 6-minute walk performance between groups.

Conclusions:

• A 6-week physical activity trial had a limited impact on reducing self-reported barriers among American Indian elders.
• Lower baseline barriers correlated with better physical activity engagement and mental health.
• Further research with larger samples is needed to explore effective interventions for this population.
