The Physical Activity Neighborhood Environment Scale (PANES) has been used internationally; however, PANES properties have not been assessed in all geographical contexts. Our objectives were to assess the reliability and validity of an online and paper version of the PANES in Canadian adults. Reliability was estimated using intraclass correlation coefficients (ICC), percent of overall agreement (p0) and Cohen's Kappa coefficient (κ). Lower 95% confidence interval (CI) ICC ranged from 0.10 to 0.70. Lower 95%CI for κ statistics ranged from −0.20 to 0.64 and p0 ranged from 80.1% to 95.7%. Cronbach's alpha coefficients (α) estimated internal consistency of the PANES (α = 0.58 for the paper version and α = 0.55 for the online version). Mean scores for the PANES Built Environment Index (BEI) significantly differed by neighborhood street pattern (p <.05). The PANES administrated via paper or online provides reliable overall agreement and valid estimates of the self-reported neighborhood built environment supportiveness of physical activity.

Background Self-reported and objectively-determined neighborhood built characteristics are associated with physical activity, yet little is known about their combined influence on walking. This study: 1) compared self-reported measures of the neighborhood built environment between objectively-determined low, medium, and high walkable neighborhoods; 2) estimated the relative associations between self-reported and objectively-determined neighborhood characteristics and walking and; 3) examined the extent to which the objectively-determined built environment moderates the association between self-reported measures of the neighborhood built environment and walking. Methods A random cross-section of 1875 Canadian adults completed a telephone-interview and postal questionnaire capturing neighborhood walkability, neighborhood-based walking, sociodemographic characteristics, walking attitudes, and residential self-selection. Walkability of each respondent's neighborhood was objectively-determined (low [LW], medium [MW], and high walkable [HW]). Covariate-adjusted regression models estimated the associations between weekly participation and duration in transportation and recreational walking and self-reported and objectively-determined walkability. Results Compared with objectively-determined LW neighborhoods, respondents in HW neighborhoods positively perceived access to services, street connectivity, pedestrian infrastructure, and utilitarian and recreation destination mix, but negatively perceived motor vehicle traffic and crime related safety. Compared with residents of objectively-determined LW neighborhoods, residents of HW neighborhoods were more likely (p < .05) to participate in (odds ratio[OR] = 3.06), and spend more time, per week (193 min/wk) transportation walking. Perceived access to services, street connectivity, motor vehicle safety, and mix of recreational destinations were also significantly associated with transportation walking. With regard to interactions, HW x utilitarian destination mix was positively associated with participation, HW x physical barriers and MW x pedestrian infrastructure were positively associated with minutes, and HW x safety from crime was negatively associated with minutes, of transportation walking. Neither neighborhood type nor its interactions with perceived measures of walkability were associated with recreational walking, although perceived aesthetics was associated with participation (OR = 1.18, p < .05). Conclusions Objectively-determined and self-reported built characteristics are associated with neighborhood-based transportation walking. The objectively-determined built environment might moderate associations between perceptions of walkability and neighborhood-based transportation walking. Interventions that target perceptions in addition to modifications to the neighborhood built environment could result in increases in physical activity among adults. [ABSTRACT FROM AUTHOR]

Background. Adolescent friendships have been linked to physical activity levels; however, network characteristics have not been broadly examined. Method. In a cross-sectional analysis of 1061 adolescents (11-15 years), achieving 60 minutes/day of moderateto- vigorous physical activity (MVPA) and participating in over 2 hours/day of sedentary behaviour were determined based on friendship network characteristics (density; proportion of active/sedentary friends; betweenness centrality; popularity; clique membership) and perceived social support. Results. Adolescents with no friendship nominations participated in less MVPA. For boys and girls, a ten percent point increase in active friends was positively associated with achievement of 60 minutes/day of MVPA (OR 1.11; 95% CI 1.02-1.21, OR 1.14; 95% CI 1.02-1.27, resp.). For boys, higher social support from friends was negatively associated with achieving 60 minutes/day ofMVPA(OR 0.63; 95%CI 0.42-0.96). Compared with lowdensity networks, boys in higher density networks were more likely to participate in over 2 hours/day of sedentary behaviour (OR 2.93; 95% CI 1.32-6.49). Social support fromfriends alsomodified associations between network characteristics andMVPAand sedentary behaviour. Conclusion. Different network characteristics appeared to have different consequences.The proportion of active close friends was associated withMVPA, while network density was associated with sedentary behaviour.This poses challenges for intervention design.

Background Environmental audit tools must be reliable in order to accurately estimate the association between built environmental characteristics and bicycling injury risk. Objective To examine the inter-rater agreement of a built environment audit tool within a case-control study on the environmental determinants of bicycling injuries. Methods Auditor pairs visited locations where bicycling injuries occurred and independently recorded location characteristics using the Systematic Pedestrian and Cyclist Environmental Scan (SPACES). Two case groups were defined: (1) where a bicyclist was struck by a motor-vehicle (MV) and (2) where the bicyclist's injuries required hospitalisation. The two corresponding control groups were (1) where non-MV bicycle-related injuries occurred and (2) where minor bicycle-related injuries occurred. Inter-rater reliability of each item on the tool was assessed using observed agreement and κ with 95% CI. Results Ninety-seven locations were audited. Interobserver agreement was generally high (≥95%); most items had a 1-2% difference in responses. Items with ≥5% differences between raters included path condition, slope and obstructions. For land use, path and roadway characteristics,κ ranged from 0.3 for presence of offices and cleanliness to 0.9 for schools and number of lanes; overall, 78% of items had at least substantial agreement (κ≥0.61). For bicyclists struck by a MV the proportion of items with substantial agreement was 60%, compared with 73% for non-MV related injuries. For hospitalisations and minor bicycle-related injuries, 76% of items had substantial agreement. Conclusions Agreement was substantial for most, but not all SPACES items. The SPACES provides reliable quantitative descriptions of built environmental characteristics at bicycling injury locations. [ABSTRACT FROM AUTHOR]

Background: Walking in neighborhood environments is undertaken for different purposes including for transportation and leisure. We examined whether sidewalk availability was associated with participation in, and minutes of neighborhood-based walking for transportation (NWT) and recreation (NWR) after controlling for neighborhood self-selection. Method: Baseline survey data from respondents (n = 1813) who participated in the RESIDential Environment (RESIDE) project (Perth, Western Australia) were used. Respondents were recruited based on their plans to move to another neighborhood in the following year. Usual weekly neighborhood-based walking, residential preferences, walking attitudes, and demographics were measured. Characteristics of the respondent's baseline neighborhood were measured including transportation-related walkability and sidewalk length. A Heckman two-stage modeling approach (multivariate Probit regression for walking participation, followed by a sample selection-bias corrected OLS regression for walking minutes) estimated the relative contribution of sidewalk length to NWT and NWR. Results: After adjustment, neighborhood sidewalk length and walkability were positively associated with a 2.97 and 2.16 percentage point increase in the probability of NWT participation, respectively. For each 10 km increase in sidewalk length, NWT increased by 5.38 min/wk and overall neighborhood-based walking increased by 5.26 min/wk. Neighborhood walkability was not associated with NWT or NWR minutes. Moreover, sidewalk length was not associated with NWR minutes. Conclusions: Sidewalk availability in established neighborhoods may be differentially associated with walking for different purposes. Our findings suggest that large investments in sidewalk construction alone would yield small increases in walking. [ABSTRACT FROM AUTHOR]

Older adults requiring home care service have a high risk of depression. Instruments for detecting depression among older adults, however, are often too long and detailed for easy administration by nontrained staff in large service-based settings.This study examined the measurement properties (test—retest reliability, concurrent validity, and cross-modality correspondence) of a single-item screener for depressive symptoms among older adults receiving home care services. Reliability was assessed (n = 65) by administering the single-item depression screener to the same participants on two occasions 7 days apart. Validity was assessed (n = 191) by comparing depressed participants from the single-item depression screener versus Geriatric Depression Scale (criterion measure). Responses to the single-item depression screener administered by telephone and face-to-face interview were also compared. Findings suggest that the single-item depression screener has fair levels of reliability, validity, and cross-modality correspondence and could be used among home care recipients as a screening tool, provided that depression status is confirmed via in-depth questionnaires, interviews, or a clinical diagnosis.

Objectives: To examine the associations between domain-specific sedentary and active behaviors and workers' presenteeism and absenteeism in a sample of company employees. Methods: This study recruited participants (n  = 2466) from a nationwide online survey database (Japan, 2019). Participants completed a questionnaire that captured data on relative and absolute presenteeism and absenteeism and domain-specific physical activity and sedentary behaviors. Results: Daily minutes of work-related physical activity were negatively associated with relative absenteeism. Daily minutes of leisure-related physical activity were positively associated with absolute presenteeism (ie, better productivity). Daily minutes of total physical activity were negatively and positively associated with relative absenteeism and absolute presenteeism (ie, better productivity). There was also a positive association between car sitting time and absolute absenteeism. Conclusions: A change in work culture and practices that support active behaviors at work and outside of work may improve employee's productivity indices. [ABSTRACT FROM AUTHOR]
