Abstract Previous studies have reported associations of sedentary time with worse health outcomes in older adults. Yet, little is known about the relationships between the contexts of sedentary time and health outcomes. The purpose of this study was to examine associations of physical function with time spent in a variety of sedentary behavior domains. We analyzed data from the 2016 National Health and Aging Trends Study, a nationally representative sample of community-dwelling Medicare beneficiaries. Estimated time being sedentary by domains (e.g., TV watching, computer use, resting/napping, eating, transportation, socializing, sitting and doing hobbies) were collected from a subset of the sample population (N=2157). The Short Physical Performance Battery (SPPB) measured physical function. Linear regression models were conducted adjusting for sociodemographics, health conditions, pain, and dementia. More time watching TV and resting/napping was significantly associated total SPPB scores (p < 0.01). In adjusted models, lower SPPB scores were significantly associated with more time/day spent sitting and watching television or resting (ɮ =-0.16 hours; 95% Confidence Interval (CI): -.024, -0.08 for TV watching and ɮ =-0.63 hours; 95% CI: -0.80, -0.46 for resting). Average time in computer use, eating, transportation, hobbies, or social activities did not differ by physical function level. Associations between physical function and sedentary time vary by the context. Social or engaging sedentary activities do not appear to be associated with physical function limitations in the same way as passive sedentary domains like television viewing and resting. Context should be considered in evaluating relationships of sedentary time with health outcomes.

The purpose of this study was to examine the effectiveness and feasibility of translating a 4-week “Stand Up and Move More” (SUMM) intervention by state aging units to older adults ( N = 56, M age = 74 years). A randomized controlled trial assessed sedentary behavior, physical function, and health-related quality of life (HRQoL) before and after the intervention. Participants included healthy community-dwelling, sedentary (sit > 6 hr/day) and aged ≥ 55 years adults. For the primary outcome, the SUMM group ( n = 31) significantly ( p < .05) reduced total sedentary time post-intervention by 68 min/day on average (Cohen’s d = −0.56) compared with no change in the wait-list control group ( n = 25, Cohen’s d = 0.12). HRQoL and function also improved ( p < .05) in the SUMM group post-intervention. Workshop facilitators indicated the intervention was easy to implement, and participants expressed high satisfaction. The SUMM intervention reduced sedentary time, improved physical function and HRQoL, and was feasible to implement in community settings.

Objectives:To characterize patterns of sedentary behavior and physical activity in older adults recovering from hip fracture and to determine characteristics associated with activity.Methods:Community-dwelling, Canadian adults (65 years+) who sustained hip fracture wore an accelerometer at the waist for seven days and provided information on quality of life, falls self-efficacy, cognitive functioning, and mobility.Results:There were 53 older adults (mean age [SD] 79.5 [7.8] years) enrolled in the study; 49 had valid data and demonstrated high levels of sedentary time (median [p10, p90] 591.3 [482.2, 707.2] minutes/day), low levels of light activity (186.6 [72.6, 293.7]), and MVPA (2 [0.1, 27.6]), as well as few daily steps (2467.7 [617.1, 6820.4]). Regression analyses showed that age, gender, gait speed, and time since fracture were associated with outcomes.Conclusions:Older adults have long periods of sedentary time with minimal activity. Results are a call to action to encourage people to sit less and move more.

Community Dwelling Older Adults

Abstract Background With population aging, a key question is whether new cohorts of older people are in better health than previous ones. This study aimed to compare the physical and cognitive performance of community-dwelling older adults assessed at similar age in 2005, 2010, and 2015. Methods This repeated cross-sectional analysis used data from the Lausanne cohort 65+, a three random sample population-based study. Performance of participants aged 66–71 years in 2005 (N = 1,309), 2010 (N = 1,253), and 2015 (N = 1,328) was compared using a battery of six physical and four cognitive tests. Analyses included tests for trend across samples and multivariable linear regression models. Results Adjusted performance in all four timed physical tests (gait speed, Timed Up-and-Go, five times chair stand, and Moberg Picking-Up) improved across samples from 2005 to 2015, by +12.7% (95% confidence interval {CI} +10.5%; +14.9%) to +20.4% (95% CI +17.7%; +23.0%) in females, and by +10.6% (95% CI +8.7%; +12.4%) to +16.7% (95% CI +13.4%; +20.0%) in males. In contrast, grip strength and balance did not improve across samples. Adjusted cognitive performance showed no change in the Trail Making Test, but worsened significantly across samples for the Mini-Mental State Examination, verbal fluency, and the clock drawing test in both females (−1.9% [95% CI −2.7%; −1.1%] to −6.7% [95% CI −8.9%; −4.6%]) and males (−2.5% [95% CI −3.4%; −1.6%] to −8.0% [95% CI −11.1%; −4.9%]). Conclusions Over the last decade, performance of adults aged 66–71 years improved significantly in timed physical tests but worsened in most cognitive measures among later-born samples.

Intervention Effects

Abstract Sedentary behavior (SB) is associated with numerous negative health outcomes, independent of physical activity behavior. Older adults are the most sedentary population in the United States. Understanding the effects and characteristics of existing interventions to reduce SB can inform practice, future research, and public health initiatives to improve older adults’ health. We conducted a systematic review and meta-analysis to examine existing SB intervention research among older adults and quantitatively synthesize intervention effects. Comprehensive searches were conducted to identify studies testing interventions to reduce SB time among adults at least 60 years old. Data on study design, intervention content and delivery, and participant characteristics were extracted from eligible studies. Standardized mean difference effect sizes (Cohen’s d) were synthesized using a random-effects model for two-group pretest–posttest design studies. Twenty-two reports describing 17 distinct studies were included in the narrative synthesis, with eight studies included in the meta-analysis (k = 8; n = 1,024). Most interventions were theory-driven and employed multiple strategies, including education, self-monitoring, and goal setting. Although SB interventions significantly reduced total sedentary time, the overall effect was small (d = −0.25, 95% confidence interval [−0.50, 0.00], p = .05). Studies were significantly heterogeneous (Q = 22.34, p &lt; .01); however, the small number of comparisons prevented moderator analyses. Practitioners should employ diverse SB-specific strategies to encourage older adults to reduce time spent sedentary. To develop public health programs targeting SB in older adults, future research should include measures of time spent in specific SB and duration/number of breaks in sedentary time and investigate SB intervention effects on health outcomes.

Abstract Peripheral artery disease (PAD) is associated with increased rates of physical disability in older adults, yet few interventions exist to reduce this risk. Intermittent claudication, exertional calf symptoms that resolve within 10 minutes of rest, is the classic symptom for PAD, but many people with PAD are absent of these symptoms. Ankle brachial index (ABI) is a non-invasive measure that identifies the presence and severity of lower extremity arterial obstruction due to atherosclerosis. We studied whether abnormal ABI is associated with increased time spent in sedentary behavior in a large sample of community-dwelling older men and women (70-89 years) enrolled in the Lifestyle Interventions and Independence for Elders (LIFE) study. Older adults underwent an ABI test and then wore a tri-axial accelerometer on the hip for up to seven days. Total accumulated sedentary time and sedentary time spent in bout lengths of 10minutes or more, 30 minutes or more, and 60 minutes or more were calculated. ABI values, divided into PAD (&lt;.90, n=156) and non-PAD (0.90 - 1.40, n=960), were evaluated in covariate-adjusted regression models adjusting for age, body mass index, comorbidity presence, gender and smoking. Older adults with PAD had significantly higher total accumulated time spent in sedentary behavior than those without PAD (13.1 minutes per day, p&lt;0.02). No associations were found with longer bout lengths of sedentary time. These results suggest that older adults with PAD accumulate more time in shorter bouts of sedentary behavior. Future interventions may consider targeting short sedentary bout-lengths for reducing PAD symptoms.

Little is known about how sedentary behavior (SB) metrics derived from hip- and thigh-worn accelerometers agree for older adults. Thigh-worn activPAL (AP) micro monitors were concurrently worn with hip-worn ActiGraph (AG) GT3X+ accelerometers (with SB measured using the 100 counts per minute [cpm] cut point; AG100cpm) by 953 older adults (age 77 ± 6.6, 54% women) for 4–7 days. Device agreement for sedentary time and five SB pattern metrics was assessed using mean error and correlations. Logistic regression tested associations with four health outcomes using standardized (i.e., z scores) and unstandardized SB metrics. Mean errors (AP − AG100cpm) and 95% limits of agreement were: sedentary time −54.7 [−223.4, 113.9] min/day; time in 30+ min bouts 77.6 [−74.8, 230.1] min/day; mean bout duration 5.9 [0.5, 11.4] min; usual bout duration 15.2 [0.4, 30] min; breaks in sedentary time −35.4 [−63.1, −7.6] breaks/day; and alpha −.5 [−.6, −.4]. Respective Pearson correlations were: .66, .78, .73, .79, .51, and .40. Concordance correlations were: .57, .67, .40, .50, .14, and .02. The statistical significance and direction of associations were identical for AG100cpm and AP metrics in 46 of 48 tests, though significant differences in the magnitude of odds ratios were observed among 13 of 24 tests for unstandardized and five of 24 for standardized SB metrics. Caution is needed when interpreting SB metrics and associations with health from AG100cpm due to the tendency for it to overestimate breaks in sedentary time relative to AP. However, high correlations between AP and AG100cpm measures and similar standardized associations with health outcomes suggest that studies using AG100cpm are useful, though not ideal, for studying SB in older adults.

Neighborhood walkability has been associated with self-reported sedentary behavior (SB) and self-reported and objective physical activity. However, self-reported measures of SB are inaccurate and can lead to biased estimates, and few studies have examined how associations differ by gender and age. The authors examined the relationships between perceived neighborhood walkability measured with the Physical Activity Neighborhood Environment Scale (scored 1.0–4.0) and device-based SB and physical activity in a cohort of community-dwelling older adults (N = 1,077). The authors fit linear regression models adjusting for device wear time, demographics, self-rated health, and accounting for probability of participation. The Higher Physical Activity Neighborhood Environment Scale was associated with higher steps (+676 steps/point on the Physical Activity Neighborhood Environment Scale, p = .001) and sit-to-stand transitions (+2.4 transitions/point, p = .018). Though not statistically significant, stratified analyses suggest an attenuation of effect for those aged 85 years and older and for women. Consistent with previous literature, neighborhood walkability was associated with more steps, though not with physical activity time. The neighborhood environment may also influence SB.

Background: We examined the relationships between objectively assessed neighborhood environment and the patterns of sedentary behavior among older adults.Methods: A total of 126 community-dwelling older adults (aged 65 years or above) were recruited. Data on neighborhood environmental attributes (resident density, street intersection density, sidewalk availability, accessible destinations, and accessible public transportation), accelerometer-assessed total time and patterns of sedentary behavior (number and duration of bouts), and sociodemographic characteristics were collected. Multiple linear regression models were developed.Results: After adjustment for potential confounders, greater sidewalk availability was negatively related to the number of sedentary bouts (β = −0.185; 95% CI: −0.362, 0.015; p = 0.034) and sedentary bout duration (β = −0.180; 95% CI: −0.354, −0.011; p = 0.037).Conclusions: This study revealed that a favorable neighborhood environment characterized by sidewalk availability is negatively associated with sedentary behavior patterns in Taiwanese older adults. These findings are critical to inform environmental policy initiatives to prevent sedentary lifestyle in older adults.
