RESUMO
Background and Objectives: Global organizations are advocating that older persons' voices should guide communities in age-friendly design. An important aspect of age friendliness to enable daily function and health is ensuring that physical activity can occur, regardless of age, within local neighborhoods. Research Design and Methods: This study used a specific citizen science approach, Our Voice, to engage a sample (N = 13) of older adults (60 or older) in Festac Town, Nigeria. The citizen scientists' roles were to assess and identify how different aspects of the neighborhood environment act as supports or barriers to their physical activity participation. They were individually enabled using a tablet-based mobile application called the Stanford Healthy Neighborhood Discovery Tool to record a total of 156 geocoded photos and 151 commentaries of neighborhood environmental features that facilitate or hinder physical activity in and around their neighborhoods. In a guided process, the following occurred: collaborative discussions of findings with other citizen scientists to determine common targets, setting of priority targets for change, and brainstorming strategies and solutions. Results: Facilitators of physical activity included: pedestrian and traffic facilities (e.g., traffic lights, walkways); green areas and parks; multigenerational community features (e.g., programs/facilities); opportunities for social connection (e.g., neighborhood associations, churches); safety of destinations and services; and public toilets. Barriers to physical activity included: hazardous walkways/traffic; noise pollution; refuse, selling of public parks; crime (e.g., kidnapping, criminal hideouts); no safe drinking water; and ageism. The priorities for changes were social connectivity; improved pedestrian and traffic facilities; and green and beautiful environments. Discussion and Implications: In this study, both physical and social aspects of the environment were deemed important for older Nigerians to enable physical activity in their local community. This approach has a promise for age-friendly initiatives seeking local changes by meaningfully engaging older adults.
RESUMO
The trajectory of aging is profoundly impacted by the physical and social environmental contexts in which we live. While "top-down" policy activities can have potentially wide impacts on such contexts, they often take time, resources, and political will, and therefore can be less accessible to underserved communities. This article describes a "bottom-up", resident-engaged method to advance local environmental and policy change, called Our Voice, that can complement policy-level strategies for improving the health, function, and well-being of older adults. Using the World Health Organization's age-friendly cities global strategy, we describe the Our Voice citizen science program of research that has specifically targeted older adults as environmental change agents to improve their own health and well-being as well as that of their communities. Results from 14 Our Voice studies that have occurred across five continents demonstrate that older adults can learn to use mobile technology to systematically capture and collectively analyze their own data. They can then successfully build consensus around high-priority issues that can be realistically changed and work effectively with local stakeholders to enact meaningful environmental and policy changes that can help to promote healthy aging. The article ends with recommended next steps for growing the resident-engaged citizen science field to advance the health and welfare of all older adults.

Background Previous studies of older drivers have found that there are discrepancies between their retrospective self-reports of collisions and the official jurisdictional record. Objectives The purpose of this study was to examine how older drivers self-report collisions in comparison to what was recorded in their official driver abstract as well as insurance claims, in a prospective study. Methods Participants (nâ¯=â¯125, ageâ¯≥â¯70â¯years) in this study were part of the University of Manitoba site of the Candrive longitudinal study of older drivers. During the operation of the Manitoba site (2009 to 2013), participants were periodically asked to report on any collisions (at-fault or not) in which they were involved, while they were enrolled in the study. In addition, driver records (abstracts and insurance claims) from the provincial licensing agency and public insurer (Manitoba Pubic Insurance; MPI) were provided annually. Results In total there were 101 separate instances of collisions (regardless of at-fault status), whether self-reported, or recorded by MPI. There were 20 at-fault collisions that were recorded on the driver abstract. Eighteen of these collisions were self-reported by participants. In total, our participants were involved in 70 insurance claims (42 at-fault) - 61 of these were self-reported to study staff. In addition, there were 31 collisions that were self-reported to study staff, that were not reported to MPI. Conclusions In this prospective study, older drivers were diligent in reporting collisions in which they were involved. While some collisions were not reported that ultimately became a claim or part of their driver abstract, the biggest discrepancy was in the collisions that were reported to study staff but that were not reported to authorities.

BACKGROUND: Chronic health conditions associated with ageing can lead to changes in driving ability. The Canadian Driving Research Initiative for Vehicular Safety in the Elderly (Candrive II) is a 5-year prospective study funded by the Canadian Institutes of Health Research aiming to develop an in-office screening tool that will help clinicians identify potentially at-risk older drivers. Currently, no tools exist to directly predict the risk of motor vehicle collision (MVC) in this population. The American Medical Association (AMA), in collaboration with the National Highway Traffic Safety Association, has designed an opinion-based guide for assessing medical fitness to drive in older adults and recommends that physicians use the Assessment of Driving Related Skills (ADReS) as a test battery to measure vision, cognition and motor/somatosensory functions related to driving. The ADReS consists of the Snellen visual acuity test, visual fields by confrontation test, Trail Making Test part B, clock drawing test, Rapid Pace Walk, and manual tests of range of motion and motor strength. We used baseline data from the Candrive/Ozcandrive common cohort of older drivers to evaluate the validity of the ADReS subtests. We hypothesized that participants who crashed in the 2 years before the baseline assessment would have poorer scores on the ADReS subtests than participants who had not crashed. METHODS: In the Candrive/Ozcandrive study, 1230 participants aged 70 years or older were recruited from 7 Canadian cities, 1 Australian city and 1 New Zealand city, all of whom completed a comprehensive clinical assessment at study entry. The assessment included all tests selected as part of the ADReS. For this historical cohort study, data on all crashes (at-fault and non-at-fault) that occurred within 2 years preceding the baseline assessment were obtained from the respective licensing jurisdictions. Those who crashed were compared to those who had not crashed on their ADReS subtest scores using Pearson's chi-squared test and Student's t-test. RESULTS: Sixty-three of the 1230 participants (5.1%) were involved in an MVC within the 2 years preceding the baseline assessment. Contrary to our hypothesis, there were no statistically significant associations between abnormal performance on the tests constituting the ADReS and history of crash in the previous 2 years (p>0.01). DISCUSSION: We found that a history of crash in the previous 2 years was not associated with abnormalities on the subtests comprising the ADReS. This suggests the need for prospective analyses of risk factors over time to establish sensitive, valid predictors of crash that can be incorporated in clinical practice guidelines.

This study examined the associations between walking behavior and the perceived environment and personal factors among older adults. Sixty participants age 65 yr or older (mean 77 +/- 7.27, range 65-92) wore pedometers for 3 consecutive days. Perceived environment was assessed using the Neighborhood Environment Walkability Scale (abbreviated version). Physical function was measured using the timed chair-stands test. The mean number of steps per day was 5,289 steps (SD = 4,029). Regression analyses showed a significant association between personal factors, including physical function (relative rate = 1.05, p < .01) and income (RR = 1.43, p < .05) and the average daily number of steps taken. In terms of perceived environment, only access to services was significantly related to walking at the univariate level, an association that remained marginally significant when controlling for personal characteristics. These results suggest that among this sample of older adults, walking behavior was more related to personal and intrinsic physical capabilities than to the perceived environment.

This study compared the intensity and energy cost of playing 9 holes of golf with 40 min of lawn mowing in older men and determined whether both met the current recommendations for health benefits. Eighteen men (age 71.2 +/- 4.4 yr, BMI 27.3 +/- 2.3; M +/- SD) completed a graded treadmill test. During golfing and lawn-mowing field tests, oxygen consumption and walking velocity and distance were measured using a portable metabolic system and global positioning system receiver. The net energy costs of golfing and lawn mowing were 310 and 246 kcal, respectively. The average intensities in metabolic equivalents of golfing and lawn mowing were 2.8 +/- 0.5 and 5.5 +/- 0.9, respectively. Both lawn mowing and golfing met the original intensity and energy expenditure requirements for health benefits specified by the American College of Sports Medicine in 1998, but only lawn mowing met the 2007 intensity recommendations.

This study investigated whether a behaviour change program, based on Canada's Physical Activity Guide and Handbook to Healthy Active Living for Older Adults (Health Canada, 1999a), would elicit greater benefits than adoption of the guide and handbook alone. Fifteen older adults received the guide and accompanying handbook and completed the 8-week behaviour change program (mean age 73.2 +/- 5.2 yrs), while 14 others received only the guide and handbook (mean age 76.8 +/- 10.0 yrs). Functional fitness (lower body strength/endurance, flexibility, agility/dynamic balance) (Rikli and Jones, 1999), and estimated energy expenditure (DiPietro et al., 1993) were measured at baseline and after 8 weeks. Lower body strength/endurance and agility/dynamic balance differed between groups at baseline, p < 0.05. All three functional fitness tests improved in both groups over time, p< 0.05. Estimated energy expended in physical activity increased in both groups over time, p < 0.05; however, there was a significantly greater increase in the behaviour-change group (Group x Time interaction, p < 0.05). Participant response to using the guide and handbook was positive. These results indicate that introduction to Canada's Physical Activity Guide and Handbook to Healthy Active Living for Older Adults leads to benefits, whether or not accompanied by program supports. The group receiving the behaviour change program had a greater increase in energy expenditure, which suggests that such an intervention may ultimately lead to greater health benefits.

BACKGROUND: Driving is a complex task that is difficult to fully characterize objectively or in a blinded fashion. The main objective of this study was to determine the usefulness of the global positioning system (GPS) and video technology for examining age-related differences in driving. In this study, GPS was used to determine the position, velocity, and acceleration of a vehicle, driven by subjects of different ages, while video footage was used to provide a detailed context of the drive. METHODS: Twenty-four subjects who were young (20 to 29; n = 6), middle-aged (30 to 64; n = 8), and older (65 years of age and older; n = 10) drove their own vehicles on a 30-km route of various types of roads, with a GPS receiver and video camera recording. RESULTS: The combination of GPS and video data allowed for the determination of many age-related driving differences. The young subjects drove faster, had a shorter deceleration distance and time, as well as a shorter acceleration time. Young subjects also had a substantially higher number of infraction demerit points primarily due to speeding, not stopping fully at stop signs, and following too closely. Although the older subjects had a smaller number of demerit points assessed, they tended to make different types of errors than the young subjects, including not stopping at all at a stop sign and turning errors. CONCLUSIONS: GPS and video technology offer new opportunities for the assessment of age-related driving performance.
