Abstract
- 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, 30min/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 24months. kcal/wk expenditure in moderate or vigorous activities was higher at 6 (p <.03, Cohen''s d 6m =.16), 12 (p <.04, d 12m =.13) and 24months (p <.01, d 24m =.16) for KAM participants, compared to UC participants. Conclusions: The KAM telephone- and mail-based PA maintenance intervention was effective at maintaining PA in both the short-term (6months) and longer-term (12 and 24months) relative to usual care.
