Background: Choose to Move is one of few scaled-up health-promoting interventions for older adults. The authors evaluated whether Choose to Move participants maintained their intervention-related gains in physical activity (PA), mobility, and social connectedness 12 months after the intervention ended. Methods: The authors assessed PA, mobility, loneliness, social isolation, and muscle strength via questionnaire and objective measures in 235 older adults at 0 months (baseline), 6 months (end of intervention), and 18 months (12-months postintervention). The authors fitted linear mixed models to examine the change in each outcome from 6 to 18 months (primary objective) and 0 to 18 months (secondary objective) and reported by age group (60–74 and ≥75 y). Results: In younger participants, PA decreased between 6 and 18 months, but remained significantly higher than at baseline. Intervention-related benefits in loneliness, social isolation, mobility, and muscle strength were maintained between 6 and 18 months in the younger participants. Older participants maintained their intervention benefits in loneliness, mobility, and muscle strength. When compared with baseline values, PA levels in older participants were unchanged, whereas social isolation increased. Conclusions: Older adults maintained some, but not all, health benefits of Choose to Move 12 months after the intervention ended. Long-term commitments are needed to deliver effective health-promoting interventions for older adults if benefits are to be maintained. [ABSTRACT FROM AUTHOR]

Background: Choose to Move (CTM), an effective health-promoting intervention for older adults, was scaled-up across British Columbia, Canada. Adaptations that enable implementation at scale may lead to 'voltage drop'—diminished positive effects of the intervention. For CTM Phase 3 we assessed: i. implementation; ii. impact on physical activity, mobility, social isolation, loneliness and health-related quality of life (impact outcomes); iii. whether intervention effects were maintained; iv) voltage drop, compared with previous CTM phases. Methods: We conducted a type 2 hybrid effectiveness-implementation pre-post study of CTM; older adult participants (n = 1012; mean age 72.9, SD = 6.3 years; 80.6% female) were recruited by community delivery partners. We assessed CTM implementation indicators and impact outcomes via survey at 0 (baseline), 3 (mid-intervention), 6 (end-intervention) and 18 (12-month follow-up) months. We fitted mixed-effects models to describe change in impact outcomes in younger (60–74 years) and older (≥ 75 years) participants. We quantified voltage drop as percent of effect size (change from baseline to 3- and 6-months) retained in Phase 3 compared with Phases 1–2. Results: Adaptation did not compromise fidelity of CTM Phase 3 as program components were delivered as intended. PA increased during the first 3 months in younger (+1 days/week) and older (+0.9 days/week) participants (p<0.001), and was maintained at 6- and 18-months. In all participants, social isolation and loneliness decreased during the intervention, but increased during follow-up. Mobility improved during the intervention in younger participants only. Health-related quality of life according to EQ-5D-5L score did not change significantly in younger or older participants. However, EQ-5D-5L visual analog scale score increased during the intervention in younger participants (p<0.001), and this increase was maintained during follow-up. Across all outcomes, the median difference in effect size, or voltage drop, between Phase 3 and Phases 1–2 was 52.6%. However, declines in social isolation were almost two times greater in Phase 3, compared with Phases 1–2. Conclusion: Benefits of health-promoting interventions—like CTM—can be retained when implemented at broad scale. Diminished social isolation in Phase 3 reflects how CTM was adapted to enhance opportunities for older adults to socially connect. Thus, although intervention effects may be reduced at scale-up, voltage drop is not inevitable. [ABSTRACT FROM AUTHOR]

One new case of dementia is detected every 4 seconds and no effective drug therapy exists. Effective behavioural strategies to promote healthy cognitive ageing are thus essential. Three behaviours related to cognitive health which we all engage in daily are physical activity, sedentary behaviour and sleep. These time-use activity behaviours are linked to cognitive health in a complex and dynamic relationship not yet fully elucidated. Understanding how each of these behaviours is related to each other and cognitive health will help determine the most practical and effective lifestyle strategies for promoting healthy cognitive ageing. In this review, we discuss methods and analytical approaches to best investigate how these time-use activity behaviours are related to cognitive health. We highlight four key recommendations for examining these relationships such that researchers should include measures which (1) are psychometrically appropriate; (2) can specifically answer the research question; (3) include objective and subjective estimates of the behaviour and (4) choose an analytical method for modelling the relationships of time-use activity behaviours with cognitive health which is appropriate for their research question.

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. [ABSTRACT FROM AUTHOR]

Background and Purpose: Prolonged sedentary time and limited physical activity can result in deleterious effects on health and mobility, especially for older adults with fall-related hip fracture. Therefore, the purpose of this study was to examine the effect of a multidisciplinary clinic on sedentary behavior and physical activity (prespecified secondary outcomes) and provide descriptions of activity patterns over 1 year for men and women. Methods: We conducted a parallel-group, single-blinded randomized controlled trial comparing a multidisciplinary clinic and usual care (intervention) with usual care (control). We recruited 53 community-dwelling older adults aged 65+ years who were 3 to 12 months postfracture and collected data at baseline, 6, and 12 months; study staff were blinded to group allocation. The clinic included a geriatric assessment by the geriatrician, physiotherapist, and occupational therapist. Referrals were made to other professionals, when indicated. We collected the accelerometer-measured sedentary behavior and physical activity at 3 time points. We used linear mixed-effects models to compare groups at 6 and 12 months and mixed models to compare outcomes between men and women. Results: Participants were sedentary for more than 10 hours of a 13-hour day, and there were no significant differences between the study groups at 6 months (2.4 [95% confidence interval: −22.4 to 27.2] minutes) or 12 months (−3.7 [95% confidence interval: −33.6 to 26.1] minutes). Compared with women, men spent 47.2 min/d more in sedentary time (P =.052) and 43.8 min/d less in light physical activity (P =.047). Discussion: Older adults after hip fracture spend prolonged periods of waking hours sedentary with very little activity. [ABSTRACT FROM AUTHOR]

Introduction: Statins are widely used to inhibit cholesterol production in the liver among people with hypercholesterolemia. A recent epidemiological study in the UK has shown that statin use (unlike elevated BMI) is not associated with an increased risk of Achilles tendon rupture. However, because of laboratory reports suggesting a negative influence of statins on tenocyte metabolism, we decided to directly compare the Achilles tendon structure (cross-sectional area and longitudinal collagen organization) in regular statin users compared to non-users. Methods: We conducted ultrasound tissue characterization (UTC) of the Achilles tendon in statin users and a comparison group of similar age and gender. Statin users and control participants were recruited from May 10 2015 to February 17 2017 through a cardiovascular health centre and from the general community. Cross-sectional area of the Achilles tendon and longitudinal collagen organization (% type I echoes) were assessed using quantitative ultrasound tissue characterization by a blinded observer at a predetermined location (2 cm proximal to the calcaneus). Results: Sixty-six individuals who were either taking statins for at least one year (ST, n = 33) or a comparison group who had never taken statins (CG, n = 33) were included in the study. The Achilles tendon cross-sectional area (ST 59.7 (13) mm2, CG 59.9 (8.5) mm2) and proportion of echo-type I patterns [ST 70 (10)%, CG 74 (13)%] were equivalent in the two groups. In contrast, there was a negative correlation between BMI (rs = -0.25, p = 0.042) and type I echo values. Obese individuals demonstrated a significantly lower percentage of type I echoes (62 (11)%) than individuals of normal body mass index (73 (10)% p<0.05). Conclusion: These findings demonstrate that there is no evidence of a negative statin influence on Achilles tendon structure. Given earlier reports that the risk of Achilles injury is equivalent in statin users and non-users, weightbearing exercise may be prescribed without placing the Achilles tendon at a higher risk of injury than among the general population. The results of this study are consistent with the known negative effects of elevated BMI on tendon structure, suggesting that an assessment of the Achilles tendons prior to prescribing weightbearing exercise may be prudent in obese individuals.

Objectives: Physical activity is a key health behavior that reduces disease risk, and yet most older adults are not very active. This study examined time-varying associations between physical activity and a recognized barrier, namely, precipitation. And it examined the moderating role of physical activity intentions and functional mobility on precipitation-physical activity associations. Method: One hundred and twenty-six older adults (M age = 72 years; 64% women) from Metro Vancouver provided health and background information and wore triaxial accelerometers for up to 10 consecutive days. Daily weather information was collected from local weather stations. Results: Multilevel models corroborate previous research by showing that older adults engaged in less physical activity on days with increased precipitation across four indices: activity counts, step counts, minutes of moderate to vigorous physical activity (MVPA), and bout-corrected minutes of MVPA. Older adults with strong physical activity intentions engaged in more physical activity overall. Physical activity intentions also modified the association between time-varying precipitation and activity counts and step counts, whereas functional mobility moderated the negative association between precipitation and activity counts and minutes of MVPA. Discussion: Findings highlight the important role of time-varying influences on physical activity and how these associations are moderated by psychological and biological factors.

Background: There is a physical inactivity pandemic around the world despite the known benefits of engaging in physical activity. This is true for individuals who would receive notable benefits from physical activity, in particular those with mood disorders. In this study, we explored the factors that facilitate and impede engagement in physical activity for individuals with a mood disorder. The intent was to understand the key features of a community based physical activity program for these individuals. Methods: We recruited and interviewed 24 participants older than 18 with Major Depressive Disorder or Bipolar II. The interviews were conducted by peer researchers. The interviews were transcribed and analyzed using NVivo 10™. Thematic analysis was used to analyze the data. Results: The facilitators to physical activity include being socially connected with family and friends, building a routine in daily life, and exposure to nature. The barriers to physical activity include the inability to build a routine owing to a mood disorder, and high cost. The ideal exercise program comprises a variety of light-to-moderate activities, offers the opportunity to connect with other participants with a mood disorder, and brings participants to nature. The average age of our participants was 52 which could have influenced the preferred level of intensity. Conclusion: The individuals in this study felt that the key features of a physical activity program for individuals with a mood disorder must utilize a social network approach, take into account the preferences of potential participants, and incorporate nature (both green and blue spaces) as a health promotion resource.

This article describes major topics discussed from the 'Economics of Physical Inactivity Consensus Workshop' (EPIC), held in Vancouver, Canada, in April 2011. Specifically, we (1) detail existing evidence on effective physical inactivity prevention strategies; (2) introduce economic evaluation and its role in health policy decisions; (3) discuss key challenges in establishing and building health economic evaluation evidence (including accurate and reliable costs and clinical outcome measurement) and (4) provide insight into interpretation of economic evaluations in this critically important field. We found that most methodological challenges are related to (1) accurately and objectively valuing outcomes; (2) determining meaningful clinically important differences in objective measures of physical inactivity; (3) estimating investment and disinvestment costs and (4) addressing barriers to implementation. We propose that guidelines specific for economic evaluations of physical inactivity intervention studies are developed to ensure that related costs and effects are robustly, consistently and accurately measured. This will also facilitate comparisons among future economic evidence. [ABSTRACT FROM AUTHOR]

In this article we examine the experiences of older women who participated in a randomized controlled trial (RCT) physical activity intervention designed to test the influence of exercise on executive function (cognition). Specifically, we were interested in why these women joined the RCT exercise program (uptake) and why they continued (adherence). Data were collected from 84 older women enrolled in the RCT (average age 69.6 years) in 10 focus group sessions at two time points. Data were analyzed using framework analysis. The findings showed that a range of factors influence both exercise uptake and adherence: timing in one's life, previous experience, physical benefits, personal barriers, and commitment. Our research findings have implications for understanding exercise and physical activity in later life as well as offering suggestions for programming. [ABSTRACT FROM AUTHOR]

The article focuses on a study which compares tibial bone strength between boys and girls who participated in school-based program of physical activity. Boys who attended the program have a greater increase in bone strength index than those who did not attend it. They also have a greater increase in strength strain index. The study concluded that a physical fitness program of improves bone mineral at the distal tibia in prepubertal boys.

Objectives: To determine whether exercise-induced reductions in fall risk are maintained in older women 1 year after the cessation of three types of interventions—resistance training, agility training, and general stretching. Design: One-year observational study. Setting: Community. Participants: Ninety-eight women aged 75 to 85 with low bone mass. Measurements: Primary outcome measure was fall risk, measured using the Physiological Profile Assessment tool. Secondary outcome measures were current physical activity level, assessed using the Physical Activity Scale for the Elderly, and formal exercise participation, assessed using an interview. Results: At the end of the follow-up, the fall risk of former participants of all three exercise programs was maintained (i.e., still reduced) from trial completion. Mean fall risk value at the end of follow-up was 43.3% lower than mean baseline value in former participants of the resistance-training group, 40.1% lower in the agility-training group, and 37.4% lower in the general stretching group. Physical activity levels were also maintained from trial completion. Specifically, there was a 3.8% increase in physical activity from baseline for the resistance-training group, a 29.2% increase for the agility-training group, and a 37.7% increase for the general stretching group. Conclusion: After three types of group-based exercise programs, benefits are sustained for at least 12 months without further formal exercise intervention. Thus, these 6-month exercise interventions appeared to act as a catalyst for increasing physical activity with resultant reductions in fall risk profile that were maintained for at least 18 months in older women with low bone mass.

The article discusses various reports published within the issue, including one on seven evidence-based investments for limiting physical inactivity-related disease, another on the link between the physical activity level of adolescents and children and academic achievement and a report on a questionnaire for assessing sedentary behavior in the primary care setting.

The author reflects on the global public health pandemic of physical inactivity. He states that, physical activity is the best solution for this problem, rather than any other prescribed drug. He stresses on reducing physical inactivity by focusing on the theory titled 7 investments, propounded by professor Fiona Bull. He also discusses the services of primary care sector for the patients of physical inactivity.

The article focuses on the issuing of a position statement by the Canadian Academy of Sport and Exercise Medicine regarding physical activity (PA) prescription for addressing risk factor for the prevention and management of chronic diseases. Topics include role of physicians in the dissemination of PA recommendations, role of exercise prescription, and effective dose of exercise for prevention and management of chronic diseases.

Exercise during growth has a positive influence on bone mineral accrual, yet little is known about how bone geometry and strength adapt to loading during growth. Our primary objective was to compare changes in proximal femur bone geometry and strength between 31 prepubertal (Tanner Stage 1) boys who participated in a school-based, high-impact circuit intervention (12 min, three times a week) for 20 months and 33 maturity-matched controls. Our secondary objective was to compare changes in total body (TB), proximal femur (PF), and lumbar spine (LS) bone mineral content (BMC) and bone area (BA) in these groups. We assessed geometric variables and bone strength at the narrow neck (NN), intertrochanteric (TR) region, and femoral shaft regions by applying the Hip Structure Analysis program to proximal femur dual energy X-ray absorptiometry scans (DXA, Hologic QDR 4500). Further, we assessed total body, lumbar spine, and proximal femur BMC and BA by DXA and derived total body lean mass and fat mass from total body scans. Intervention (10.2 ± 0.5 years) and control boys (10.1 ± 0.5 years) had similar baseline height (140.8 vs. 141.3 cm) and weight (36.9 vs. 35.4 kg), and average 20-month physical activity scores (Physical Activity Questionnaire for Children, PAQ-C) and calcium intakes (861 vs. 852 mg/day, food frequency questionnaire). Twenty-month height and weight changes were not significantly different between groups; lean mass changed more (P < 0.05) in intervention boys (22.8%) than control boys (18.6%). At the NN region, intervention boys had greater bone expansion on both the periosteal (+2.6%, P = 0.1) and endosteal (+2.7%, P = 0.2) surfaces, resulting in significantly greater changes in section modulus (bone bending strength) (+7.5%, P = 0.02, ANCOVA, adjusting for height change, final Tanner Stage, and baseline bone values). Changes at the intertrochanteric and femoral shaft regions were not significantly different between groups. Femoral neck (FN) BMC changes were significantly greater in intervention boys (+4.3%, P < 0.01); changes in BA and BMC for other regions were not significantly different between groups. In summary, a school-based, high-impact exercise intervention implemented three times a week for 12 min is an effective strategy for site-specific gains in bone strength at the narrow neck region of the proximal femur.
