Predicting exercise in older Americans: using the theory of planned behavior

Area of Science:

• Gerontology
• Behavioral Science
• Public Health

Background:

• Promoting physical activity in older Americans is a national priority due to exercise benefits and low participation rates.
• Understanding factors influencing exercise behavior in this demographic is crucial for effective health interventions.

Purpose of the Study:

• To assess the utility of the theory of planned behavior in predicting exercise intention and behavior among older adults.
• To identify key psychological and social factors associated with regular physical activity in this population.

Main Methods:

• A survey was administered to military beneficiaries.
• The study utilized the theory of planned behavior constructs (attitude, social norm, perceived behavioral control) and habit.
• Physical activity levels were measured as an outcome.

Main Results:

• The response rate was 81.6%, with 61.2% of respondents engaging in regular exercise.
• Doctor's recommendation for exercise was significantly associated with regular physical activity (p < 0.01).
• The theory of planned behavior model, including habit, strongly predicted intent to exercise (R2 = 0.468, p < 0.001).

Conclusions:

• The theory of planned behavior serves as a valid framework for predicting exercise intention and actual physical activity in older adults.
• Clinicians play a vital role in promoting exercise, and this theoretical model can guide their efforts.
