Effect of telephone counseling on physical activity for low-active older people in primary care: a randomized, controlled trial.

OBJECTIVES: To assess the long-term effectiveness of a telephone counseling intervention on physical activity and health-related quality of life in low-active older adults recruited through their primary care physician.
DESIGN: Randomized, controlled trial.
SETTING: Three primary care practices from different socioeconomic regions of Auckland, New Zealand. PARTICIPANTS: One hundred and eighty-six low-active adults (aged 65) recruited from their primary care physicians' patient databases. INTERVENTION: Eight telephone counseling sessions over 12 weeks based on increasing physical activity. Control patients received usual care. MEASUREMENTS: Change in physical activity (as measured using the Auckland Heart Study Physical Activity Questionnaire) and quality of life (as measured using the Short Form-36 Health Survey (SF-36)) over a 12-month period.
RESULTS: Moderate leisure physical activity increased by 86.8 min/wk more in the intervention group than in the control group (P=.007). More participants in the intervention group reached 2.5 hours of moderate or vigorous leisure physical activity per week after 12 months (42% vs 23%, odds ratio=2.9, 95% confidence interval=1.33-6.32, P=.007). No differences on SF-36 measures were observed between the groups at 12 months.
CONCLUSION: Telephone-based physical activity counseling is effective at increasing physical activity over 12 months in previously low-active older adults.
