Maintaining physical activity among older adults: 24-month outcomes of the Keep Active Minnesota randomized controlled trial.

ABSTRACT:

Objective

To evaluate the efficacy at 6-, 12-, and 24-month follow-up of Keep Active Minnesota (KAM), a telephone and mail-based intervention designed to promote physical activity (PA) maintenance among currently active adults age 50 to 70.

Method

Participants who reported having recently increased their MVPA to a minimum of 2d/wk, 30 min/bout, (N=1049) were recruited in 2004 and 2005 from one large managed care organization in Minnesota, and randomly assigned to either treatment (KAM; N=523), or Usual Care (UC; N=526) with PA assessed using the CHAMPS questionnaire, and expressed as kcal/wk energy expenditure.

Results

We find a sustained, significant benefit of the intervention at 6, 12 and 24 months. kcal/wk expenditure in moderate or vigorous activities was higher
