PURPOSE OF THE STUDYThis study aims to describe and analyze the age differences in the 24-hour movement behavior patterns among a sample of adults and older adults with end-stage knee osteoarthritis referred for total knee arthroplasty (TKA). MATERIAL AND METHODSA total of 86 patients referred for TKA were included in this study. Sleep duration, sedentary behavior (SB), light physical activity (LPA), and moderate-to-vigorous physical activity (MVPA) were assessed using multi-day 24-hour raw data from wrist-worn accelerometers. Compositional data analysis was used to analyze the differences between the age categories. RESULTSOn average (SD), the adults were 59.0 (± 4.9) years; 63% female. The older adults were 72.4 (± 5.5) years; 58% female. The adults reached 23.9 milli-gravitational units (mg) as a mean acceleration over the whole day; 34% (8.1 h/day) of the time was classified as sleep, 48.9% (11.7 h/day) as SB, 12.1% (2.9 h/day) as LPA, and 5.1% (72.9 min/day) as MVPA. The older adults reached 21.3 mg; 35.2% (8.4 h/day) of the time was classified as sleep, 50.4% (12.1 h/day) as SB, 11.3% (2.7 h/day) as LPA, and 3.1% (44.9 min/day) as MVPA. Compared with the older adults, the proportion of time spent in total MVPA (P = 0.008) and MVPA bouts of ≥1 min were greater (P ≤ 0.028) in the adult group, while the proportion of time spent in total SB was lower (P = 0.045). No age difference was found for the proportion of time spent asleep. DISCUSSIONSleep, SB, and PA are exclusive and exhaustive parts of the overall 24-h day. Using accelerometer-based measures of 24-hour movement behavior to describe these behaviors more accurately is crucial for a better understanding of patients with end-stage KOA. CONCLUSIONSOur findings suggest that the adults and older adults referred for TKA are physically active despite suffering from severe knee osteoarthritis. Such a high level of physical activity may be difficult to increase by TKA postoperatively. If replicated by other studies, 24-hour movement behaviors should be implemented among the examinations required before TKA.
Background: There are few studies assessing the health of older women with respect to their physical activity. This study sought to determine whether changes in the physical activity of 59 women aged 60+ measured seven years apart and the risk of the participants developing the metabolic syndrome (MetS) were related to each other. Methods: The physical activity of the participants was measured using the accelerometers in 2009 and 2016. Their risk for the MetS was assessed as per the NCEP-ATP III criteria. Results: The number of steps the participants took daily increased between 2009 and 2016 from 10.944±3,560 to 11.652±4865. Women who maintained a high level of physical activity between the measurements, or increased it, had a significantly higher mean concentration of high-density cholesterol in 2016 (80.3 vs. 64.5 mg/dL and 79.2 vs. 66.9mg/dL, respectively). In the latter, a lower concentration of triglycerides (TG) (123.8 vs. 158.3mg/dL) was also observed. In 2016, only 7 women met 3 or more criteria for MetS compared with 24 in 2009; at the same time, the mean number of the MetS criteria met by a participant fell from 2.2±1.4 to 1.4±1.0.Conclusions: The number of MetS criteria that the participants met in 2016 was lower than in 2007, probably due to the high number of steps taken daily. Therefore, their risk of developing cardiovascular diseases was lower too.
