    BACKGROUND: Few studies have examined the associations between exercise self-efficacy, goals, and physical activity over time. PURPOSE: This study examines whether self-selected goals mediate the changes in exercise self-efficacy on physical activity over 12 months. METHODS: Data are derived from 313 older men participating in the Veterans LIFE Study. RESULTS: Changes in exercise self-efficacy were significantly associated with changes in physical activity both directly (betas = 0.25 and 0.24, p

    Enhanced fitness: a randomized controlled trial of the effects of home-based physical activity counseling on glycemic control in older adults with prediabetes mellitus.

    OBJECTIVE: To determine whether a home-based multicomponent physical activity counseling (PAC) intervention is effective in reducing glycemic measures in older outpatients with prediabetes mellitus. METHODS: Controlled clinical trial. METHODS: Primary care clinics of the Durham Veterans Affairs (VA) Medical Center between September 29, 2008, and March 25, 2010. METHODS: Three hundred two overweight (body mass index 25-45 kg/m(2) ), older (60-89) outpatients with impaired glucose tolerance (fasting blood glucose 100-125 mg/dL, glycosylated hemoglobin (HbA1c)

    Lessons learned when innovations go awry: a baseline description of a behavioral trial-the Enhancing Fitness in Older Overweight Veterans with Impaired Fasting Glucose study.
    (Translational behavioral medicine, 2011-11) Hall, KS; Pieper, CF; Edelman, DE; Yancy Jr, WS; Green, JB; Lum, H; Peterson, MJ; Sloane, R; Cowper, PA; Bosworth, HB; Huffman, KM; Cavanaugh, JT; Chapman, JG; Pearson, MP; Howard, TA; Ekelund, CC; McCraw, BL; Burrell, JB; Taylor, GA; Morey, MC
    Individuals diagnosed with impaired glucose tolerance (i.e., prediabetes) are at increased risk for developing diabetes. We proposed a clinical trial with a novel adaptive randomization designed to examine the impact of a home-based physical activity (PA) counseling intervention on metabolic risk in prediabetic elders. This manuscript details the lessons learned relative to recruitment, study design, and implementation of a 12-month randomized controlled PA counseling trial. A detailed discussion on how we responded to unforeseen challenges is provided. A total of 302 older patients with prediabetes were randomly assigned to either PA counseling or usual care. A novel adaptive design that reallocated counseling intensity based on self-report of adherence to PA was initiated but revised when rates of non-response were lower than projected. This study presents baseline participant characteristics and discusses unwelcome adaptations to a highly innovative study design to increase PA and enhance glucose metabolism when the best-laid plans went awry.

    Long-term changes in physical activity following a one-year home-based physical activity counseling program in older adults with multiple morbidities.
    (J Aging Res, 2010-12-26) Hall, KS; Sloane, R; Pieper, CF; Peterson, MJ; Crowley, GM; Cowper, PA; McConnell, ES; Bosworth, HB; Ekelund, CC; Morey, MC
    This study assessed the sustained effect of a physical activity (PA) counseling intervention on PA one year after intervention, predictors of sustained PA participation, and three classes of post-intervention PA trajectories (improvers, maintainers, and decliners) in 238 older Veterans. Declines in minutes of PA from 12 to 24 months were observed for both the treatment and control arms of the study. PA at 12 months was the strongest predictor of post-intervention changes in PA. To our surprise, those who took up the intervention and increased PA levels the most, had significant declines in post-intervention PA. Analysis of the three post-intervention PA trajectories demonstrated that the maintenance group actually reflected a group of nonresponders to the intervention who had more comorbidities, lower self-efficacy, and worse physical function than the improvers or decliners. Results suggest that behavioral counseling/support must be ongoing to promote maintenance. Strategies to promote PA appropriately to subgroups of individuals are needed.
