To describe objectively-measured physical activity levels and patterns among community-dwelling older adults with osteoporosis, impaired balance, and fear of falling, and to explore the associations with gait, balance performance, falls self-efficacy, and health-related quality of life (HRQoL).
Ninety-four individuals (75.6 ± 5.4 years) were included. Physical activity was assessed with pedometers and accelerometers. Mean steps/day, dichotomized into < 5,000 or = 5,000 steps/day, and time spent in different physical activity intensities were analyzed. Gait was assessed with a GAITRite walkway, balance performance was assessed with the modified figure-eight test and oneleg stance, falls self-efficacy was assessed with the Falls Efficacy Scale International, and HRQoL was assessed with Short Form-36.
Mean steps/day were 6,201 (991–17,156) and 40% reported < 5,000 steps/day. Participants with < 5,000 steps/day spent more time sedentary, had slower gait speed, poorer balance performance, and lower HRQoL than participants with ≥ 5,000 steps/day. No participants with < 5,000 met the recommended level of physical activity.

Physical activity on prescription, as a method for increasing physical activity, has attracted attention in recent years. However, few studies have examined adherence as a primary outcome variable. The aim of this article was to examine self-reported adherence to individualized prescribed physical activity in a routine primary health care setting.
Patients receiving an individualized physical activity on prescription (FaR) for prevention or treatment of disease were recruited from 13 Swedish primary health care units. Self-reported adherence, physical activity level, readiness to change to a more physically active lifestyle, and well-being were measured with questions at baseline and after 6 months in 240 patients (mean age 51, range 12 to 80, 75% women).
At the 6-month follow-up a majority (65%) of the patients reported adherence to the prescription. Partial adherence was reported by 19% and nonadherence by 16%. There was a relationship between adherence and well-being and stages of action or maintenance.
The results demonstrate that adherence to physical activity on prescription is as good as adherence to other treatments for chronic diseases. This is significant because even a small increase in physical activity is important both on an individual level and for public health.

To compare self-reported pedometer steps with accelerometer steps under free-living conditions in individuals with Parkinson’s disease (PD) or osteoporosis (OP).
Seventy-three individuals with PD and 71 individuals with OP wore a pedometer (Yamax LS2000) and an accelerometer (ActiGraph GT1M/GT3X+) simultaneously for one week.
Fifty-one individuals with PD (72.6 ± 5.3 years) and 61 with OP (75.6 ± 5.3 years) provided simultaneously recorded data for 3–7 consecutive days. Pedometer steps were significantly lower than accelerometer steps in the PD group (p = .002) but not in the OP group (p = .956). Bland-Altman plots demonstrated wide limits of agreement between the instruments in both PD (range = 6,911 steps) and OP (range = 6,794 steps).
These results suggest that the ActiGraph GT1M/GT3X+ should be preferred over the Yamax LS2000 for the assessment of steps in both research and clinical evaluations, particularly in individuals with PD or altered gait.
