Abstract
BACKGROUND Both road safety campaigns and epidemiological research into social differences in road traffic injury risk often assume that road traffic injuries occur close to home. While previous work has examined distance from home to site of collision for child pedestrians in local areas, less is known about the geographic distribution of road traffic injuries from other modes. This study explores the distribution of the distance between home residence and collision site (crash distance) by mode of transport, geographic area, and social characteristics in England. METHODS Using 10 years of road casualty data collected by the police, we examined the distribution of crash distance by age, sex, injury severity, area deprivation, urban/rural status, year, day of week, and, in London only, ethnic group. RESULTS 54% of pedestrians, 39% of cyclists, 17% of powered two-wheeler riders and 16% of car occupants were injured within 1 km of home. 82% of pedestrians, 83% of cyclists, 54% of powered two-wheeler and 53% of car occupants were injured within 5 km of home. We found some social and geographic differences in crash distance: for all transport modes injuries tended to occur closer to home in more deprived or urban areas; younger and older pedestrians and cyclists were also injured closer to home. Crash distance appears to have increased over time for pedestrian, cyclist and car occupant injuries, but has decreased over time for powered two-wheeler injuries. CONCLUSIONS Injuries from all travel modes tend to occur quite close to home, supporting assumptions made in epidemiological and road safety education literature. However, the trend for increasing crash distance and the social differences identified may have methodological implications for future epidemiological studies on social differences in injury risk.

Abstract
The aim of the study was to evaluate the impact of the state-wide dissemination of a physical activity (PA) intervention in Flanders. In 2011, a random sample was taken of the entire adult (25-75 years) population of Flanders. Data of the Flemish sample were compared with baseline data of the intervention and control group of '10 000 Steps Ghent' (2005). In total, data of the International Physical Activity Questionnaire were available of 2556 respondents (1675 of the comparison sample and 881 of the Flemish sample). Pedometer data were obtained by 269 respondents of the Flemish sample and by 1236 respondents of the comparison sample. Compared with the comparison sample of 2005, the Flemish sample reported more walking (P < 0.001), moderate (P < 0.001), vigorous (P < 0.001), work-related (P < 0.001), leisure time (P = 0.01) and household PA (P = 0.03). Step count analyses revealed that the Flemish sample took more pedometer-based daily step counts (P < 0.001) than the comparison sample. Furthermore, a higher proportion of respondents reaching the 10 000 steps/day goal (P = 0.005) was found in the Flemish sample. A positive effect of '10 000 Steps Flanders' was found. Results indicate that a state-wide approach based on socio-ecological models is an effective strategy to promote PA in a large population.

Abstract
The study aim was to investigate the health effects of a pedometer-based behavioural modification program in type 2 diabetes patients and to examine the relationship between changes in steps/day (baseline-post and baseline-follow up) and health outcomes. Ninety-two type 2 diabetes patients (69% male, mean age: 62 ± 9 years and mean BMI: 30.0 ± 2.5 kg/m(2)) were recruited and randomly assigned to an intervention or control group. The intervention consisted of one face-to-face session, pedometer use and seven telephone calls. Selection criteria included 35-75 years, 25-35 kg/m(2) and ≤12% HbA1c (108 mmol/mol). Outcome measures were assessed at baseline, post and follow up, and included systolic blood pressure, waist circumference, body mass index, glucose control (HbA1c and fasting glucose), triglycerides, total, HDL and LDL cholesterol and steps/day. The results showed no significant short- or intermediate-term differences in health outcomes between the control and intervention group. However, a threshold was identified, as HbA1c improved significantly in those who increased ≥4000 steps/day between baseline- and post-measurements (n = 18). This threshold was not applicable to any other health outcome. Hence, although the intervention successfully increased steps/day, no direct effect on health outcomes was identified. However, an increase of ≥4000 steps/day seemed a threshold to have a positive impact on HbA1c.

Associations of neighborhood characteristics with active park use: an observational study in two cities in the USA and Belgium. Int J Health Geogr 2013; 12:26. [PMID: 23648048 PMCID: PMC3651346 DOI: 10.1186/1476-072x-12-26] [Citation(s) in RCA: 58] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2013] [Accepted: 04/29/2013] [Indexed: 01/23/2023] Open
Abstract
BACKGROUND Public parks can be an important setting for physical activity promotion, but to increase park use and the activity levels of park users, the crucial attributes related to active park use need to be defined. Not only user characteristics and structural park attributes, but also characteristics of the surrounding neighborhood are important to examine. Furthermore, internationally comparable studies are needed, to find out if similar intervention strategies might be effective worldwide. The main aim of this study was to examine whether the overall number of park visitors and their activity levels depend on study site, neighborhood walkability and neighborhood income. METHODS Data were collected in 20 parks in Ghent, Belgium and San Diego, USA. Two trained observers systematically coded park characteristics using the Environmental Assessment of Public Recreation Spaces (EAPRS) tool, and park user characteristics using the System for Observing Play and recreation in Communities (SOPARC) tool. Multilevel multiple regression models were conducted in MLwiN 2.25. RESULTS In San Diego parks, activity levels of park visitors and number of vigorously active visitors were higher than in Ghent, while the number of visitors walking and the overall number of park visitors were lower. Neighborhood walkability was positively associated with the overall number of visitors, the number of visitors walking, number of sedentary visitors and mean activity levels of visitors. Neighborhood income was positively associated with the overall number of visitors, but negatively with the number of visitors being vigorously active. CONCLUSIONS Neighborhood characteristics are important to explain park use. Neighborhood walkability-related attributes should be taken into account when promoting the use of existing parks or creating new parks. Because no strong differences were found between parks in high- and low-income neighborhoods, it seems that promoting park use might be a promising strategy to increase physical activity in low-income populations, known to be at higher risk for overweight and obesity.

Does neighborhood walkability moderate the effects of intrapersonal characteristics on amount of walking in post-menopausal women? Health Place 2013; 21:39-45. [PMID: 23416232 PMCID: PMC3622785 DOI: 10.1016/j.healthplace.2012.12.007] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/29/2012] [Revised: 12/15/2012] [Accepted: 12/21/2012] [Indexed: 10/27/2022]
Abstract
This study identifies factors associated with walking among postmenopausal women and tests whether neighborhood walkability moderates the influence of intrapersonal factors on walking. We used data from the Women's Health Initiative Seattle Center and linear regression models to estimate associations and interactions. Being white and healthy, having a high school education or beyond and greater non-walking exercise were significantly associated with more walking. Neighborhood walkability was not independently associated with greater walking, nor did it moderate influence of intrapersonal factors on walking. Specifying types of walking (e.g., for transportation) can elucidate the relationships among intrapersonal factors, the built environment, and walking.

Abstract
Peripheral neuropathy is underappreciated as a potential cause of functional limitations. In the present article, we assessed the cross-sectional association between peripheral neuropathy and physical functioning and how the longitudinal association between age and functioning differed by neuropathy status. Physical functioning was measured in 1996-2008 using timed performances on stair-climb, walking, sit-to-stand, and balance tests at the Michigan site of the Study of Women's Health Across the Nation, a population-based cohort study of women at midlife (n = 396). Peripheral neuropathy was measured in 2008 and defined as having an abnormal monofilament test result or 4 or more symptoms. We used linear mixed models to determine whether trajectories of physical functioning differed by prevalent neuropathy status. Overall, 27.8% of the women had neuropathy. Stair-climb time differed by neuropathy status (P = 0.04), and for every 1-year increase in age, women with neuropathy had a 1.82% (95% confidence interval: 1.42, 2.21) increase compared with a 0.95% (95% confidence interval: 0.71, 1.20) increase for women without neuropathy. Sit-to-stand time differed by neuropathy status (P = 0.01), but the rate of change did not differ. No differences between neuropathy groups were observed for the walk test. For some performance-based tasks, poor functioning was maintained or exacerbated for women who had prevalent neuropathy. Peripheral neuropathy may play a role in physical functioning limitations and future disability.

Abstract
Although physical activity is often believed to be influenced by both environmental and individual factors, little is known about their interaction. This study explores interactions of perceived safety and social neighborhood factors with psychosocial cognitions for leisure-time walking. Cross-sectional data were obtained from residents (age 25-75 years) of 212 neighborhoods in the South-East of the Netherlands, who participated in the Dutch GLOBE study in 2004 (N = 4395, survey response 64.4%). Direct associations of, and interactions between perceived neighborhood safety, social neighborhood factors (social cohesion, social network and feeling at home) and psychosocial cognitions (attitude, self-efficacy, social influence and intention) on two outcomes of leisure-time walking [yes versus no (binary), and among walkers: minutes per week (continuous)] were analyzed in multilevel regression models. The association between attitude and participating in leisure-time walking was stronger in those who felt less at home in their neighborhood. Social influence and attitude were stronger associated with participation in leisure-time walking in those who sometimes felt unsafe in their neighborhood. A positive intention was associated with more minutes walked in those who perceived their neighborhood as unsafe among those who walked. Only limited support was found for interactions between neighborhood perceptions and psychosocial cognitions for leisure-time walking.

Abstract
Transport is associated with environmental problems, economic losses, health and social inequalities. A number of European and US cities have implemented initiatives to promote multimodal modes of transport. In Latin America changes are occurring in public transport systems and a number of projects aimed at stimulating non-motorized modes of transport (walking and cycling) have already been implemented. Based on articles from peer-reviewed academic journals, this paper examines experiences in Bogotá (Colombia), Curitiba (Brazil), and Santiago (Chile), and identifies how changes to the transport system contribute to encourage active transportation. Bus rapid transit, ciclovias, bike paths/lanes, and car use restriction are initiatives that contribute to promoting active transportation in these cities. Few studies have been carried out on the relationship between transport and physical activity. Car ownership continues to increase. The public health sector needs to be a stronger activist in the transport policy decision-making process to incorporate health issues into the transport agenda in Latin America.

Abstract
BACKGROUND The development of reliable and culturally sensitive measures of attributes of the built and social environment is necessary for accurate analysis of environmental correlates of physical activity in low-income countries, that can inform international evidence-based policies and interventions in the worldwide prevention of physical inactivity epidemics. This study systematically adapted the Neighborhood Environment Walkability Scale (NEWS) for Nigeria and evaluated aspects of reliability and validity of the adapted version among Nigerian adults. METHODS The adaptation of the NEWS was conducted by African and international experts, and final items were selected for NEWS-Nigeria after a cross-validation of the confirmatory factor analysis structure of the original NEWS. Participants (N = 386; female = 47.2%) from two cities in Nigeria completed the adapted NEWS surveys regarding perceived residential density, land use mix - diversity, land use mix - access, street connectivity, infrastructure and safety for walking and cycling, aesthetics, traffic safety, and safety from crime. Self-reported activity for leisure, walking for different purposes, and overall physical activity were assessed with the validated International Physical Activity Questionnaire (long version). RESULTS The adapted NEWS subscales had moderate to high test-retest reliability (ICC range 0.59 -0.91). Construct validity was good, with residents of high-walkable neighborhoods reporting significantly higher residential density, more land use mix diversity, higher street connectivity, more traffic safety and more safety from crime, but lower infrastructure and safety for walking/cycling and aesthetics than residents of low-walkable neighborhoods. Concurrent validity correlations were low to moderate (r = 0.10 -0.31) with residential density, land use mix diversity, and traffic safety significantly associated with most physical activity outcomes. CONCLUSIONS The NEWS-Nigeria demonstrated acceptable measurement properties among Nigerian adults and may be useful for evaluation of the built environment in Nigeria. Further adaptation and evaluation in other African countries is needed to create a version that could be used throughout the African region.

Abstract
OBJECTIVE Evidence on the effectiveness of walking and cycling interventions is mixed. This may be partly attributable to differences in intervention content, such as the cognitive and behavioral techniques (BCTs) used. Adopting a taxonomy of BCTs, this systematic review addressed two questions: (a) What are the behavior change techniques used in walking and cycling interventions targeted at adults? (b) What characterizes interventions that appear to be associated with changes in walking and cycling in adults? METHOD Previous systematic reviews and updated database searches were used to identify controlled studies of individual-level walking and cycling interventions involving adults. Characteristics of intervention design, context, and methods were extracted in addition to outcomes. Intervention content was independently coded according to a 26-item taxonomy of BCTs. RESULTS Studies of 46 interventions met the inclusion criteria. Twenty-one reported a statistically significant effect on walking and cycling outcomes. Analysis revealed substantial heterogeneity in the vocabulary used to describe intervention content and the number of BCTs coded. "Prompt self-monitoring of behavior" and "prompt intention formation" were the most frequently coded BCTs. CONCLUSION Future walking and cycling intervention studies should ensure that all aspects of the intervention are reported in detail. The findings lend support to the inclusion of self-monitoring and intention formation techniques in future walking and cycling intervention design, although further exploration of these and other BCTs is required. Further investigation of the interaction between BCTs and study design characteristics would also be desirable.

Abstract
OBJECTIVES We assessed changes in transit-associated walking in the United States from 2001 to 2009 and documented their importance to public health. METHODS We examined transit walk times using the National Household Travel Survey, a telephone survey administered by the US Department of Transportation to examine travel behavior in the United States. RESULTS People are more likely to transit walk if they are from lower income households, are non-White, and live in large urban areas with access to rail systems. Transit walkers in large urban areas with a rail system were 72% more likely to transit walk 30 minutes or more per day than were those without a rail system. From 2001 to 2009, the estimated number of transit walkers rose from 7.5 million to 9.6 million (a 28% increase); those whose transit-associated walking time was 30 minutes or more increased from approximately 2.6 million to 3.4 million (a 31% increase). CONCLUSIONS Transit walking contributes to meeting physical activity recommendations. Study results may contribute to transportation-related health impact assessment studies evaluating the impact of proposed transit systems on physical activity, potentially influencing transportation planning decisions.

Abstract
Active commuting (AC) to the workplace is a potential strategy for incorporating physical activity into daily life and is associated with health benefits. This study examined the association between health-related factors and mode of travel to the workplace. Methods. A volunteer convenience sample of employed adults completed an online survey regarding demographics, health-related factors, and the number of times/week walking, biking, driving, and using public transit to work (dichotomized as no walk/bike/drive/PT and walk/bike/drive/PT 1 + x/week). Logistic regression was used to predict the likelihood of each mode of transport and meeting PA recommendations from AC according to demographics and health-related factors. Results. The sample (n = 1175) was aged 43.5 ± 11.4 years and was primarily White (92.7%) and female (67.9%). Respondents reported walking (7.3%), biking (14.4%), taking public transit (20.3%), and driving (78.3%) to work at least one time/week. Among those reporting AC, 9.6% met PA recommendations from AC alone. Mode of travel to work was associated with several demographic and health-related factors, including age, number of chronic diseases, weight status, and AC beliefs. Discussion. Mode of transportation to the workplace and health-related factors such as disease or weight status should be considered in future interventions targeting AC.

Abstract
BACKGROUND Physical inactivity plays a role in the acquisition of heart disease, type 2 diabetes, and breast and colon cancer. The impact of such noncommunicable diseases on low- and middle-income countries is a major global health concern, but most studies in this area have focused on high-income countries. A better understanding of the factors that may influence physical activity in low- and middle-income countries is needed. PURPOSE This study describes the prevalence of cycling and walking for transportation and their association with personal and environmental factors in adults from three state capitals in Brazil. METHODS In 2007-2009, a random-digit-dialing telephone survey was conducted with residents (aged ≥18 years) of Curitiba, Vitoria, and Recife, sampled through a clustered multistage sampling process. Walking and cycling for transportation, perception of the environment related to physical activity, and demographic and health characteristics were collected. Poisson regression was used to examine associations between cycling and walking for transportation with covariates stratified by cities. All analyses were conducted in 2011. RESULTS The prevalence of bicycling for transportation was 13.4%; higher in Recife (16.0%; 95% CI=13.7, 18.4) compared to Curitiba (9.6%; 95% CI=7.8, 11.4) and Vitoria (8.8%; 95% CI=7.34, 10.1); and 26.6% for walking regularly as a mode of transportation. The adjusted analysis showed that cycling is positively associated with being male (prevalence OR [pOR]=3.4; 95% CI=2.6, 18.4) and younger (pOR=2.9; 95% CI=1.8, 4.9) and inversely associated with having a college degree (pOR=0.3; 95% CI=0.2, 0.4). Walking for transportation is inversely associated with having a college degree (pOR=0.6; 95% CI=0.5, 0.8). No strong evidence of association was found of environmental indicators with walking or bicycling. CONCLUSIONS The prevalence of active commuting was low and varied by city. Personal factors were more consistently associated with bicycling than with walking, whereas perceived environmental features were not related to active commuting.

Abstract
OBJECTIVES We compared participants from the Ciclovia (streets temporarily closed to motorized vehicles and open for pedestrians) and Cicloruta (bicycle paths) programs in Bogotá, Colombia, to assess associations of program participation with physical activity, safety, social capital, and equity. METHODS We conducted 2 cross-sectional studies in October 2009 with intercept surveys: one among 1000 Ciclovia participants and the other among 1000 Cicloruta participants. RESULTS Most Ciclovia participants met the physical activity recommendation in leisure time (59.5%), and most Cicloruta participants met it by cycling for transportation (70.5%). Ciclovia participants reported a higher perception of safety (51.2% regarding traffic and 42.4% about crime) and social capital (odds ratio = 2.0; 95% confidence interval = 1.4, 2.8) than did Cicloruta users. Most Cicloruta users reported living in low socioeconomic status categories (53.1%), had lower educational attainment (27%), and did not own cars (82.9%). Most Ciclovia participants reported living in middle socioeconomic status categories (64%), had low-to-middle educational attainment (51.1%), and did not own cars (66.1%). CONCLUSIONS The Ciclovia and Cicloruta programs have the potential to equitably promote physical activity and provide a mobility alternative in complex urban settings such as Bogotá.

Abstract
OBJECTIVE To study the demographic distribution of the victims of road traffic accidents that were presented for medico-legal autopsy in Karachi, identify fatal injuries, the identity of road users autopsied and the month-wise variation in performing autopsies. METHODS Descriptive cross-sectional study of autopsies conducted at the mortuaries of Civil Hospital Karachi, Jinnah Postgraduate Medical Centre and Abbasi Shaheed Hospital between March 1,2008 and February 28, 2009. Bodies brought in by police for partial/external autopsy were excluded. Data was collected on pre-designed proformas and was statistically analysed using SPSS 15. RESULTS Of the total 2090 autopsies performed in Karachi, 581 (27.8%) cases were victims of RTA. Of these RTA victims, 324 (55.8%) autopsies were of those between the ages of 19 and 40 years. There were 510 (87.8%) males and 71 (12.2%) females with a ratio of male: female being 7:1.This ratio was 4.2:1 for those aged 0-18 years and 11:1 for those aged 19-40 years (p = 0.05). Death was due to injury to the head in 386 (66.4%) victims, to the chest in 84 (14.5%) cases, multiple traumatic injuries in 50 (8.6%) and pelvis in 17 (2.9%) cases. The majority of the victims on whom autopsy was performed were pedestrians (n = 389, 67%) followed by motorcyclists (n = 122, 21%). On an average 48.4 +/- 7.46 autopsies were performed every month, and there was no statistically significant variation in autopsies on this count. CONCLUSION There was a male preponderance, but the significant differences in two age groups need to be correlated with the incidence of RTAs in each sex in that age group and the compliance levels of getting females autopsied.

Sigmundová D, Vašíčková J, Stelzer J, Řepka E. The influence of monitoring interval on data measurement: an analysis of step counts of university students. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2013; 10:515-27. [PMID: 23358235 PMCID: PMC3635159 DOI: 10.3390/ijerph10020515] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 08/22/2012] [Revised: 01/04/2013] [Accepted: 01/23/2013] [Indexed: 11/16/2022]
Abstract
The pedometer is a widely used research tool for measuring the level and extent of physical activity (PA) within population subgroups. The sample used in this study was drawn from a population of university students to examine the influence of the monitoring interval and alternate starting days on step-count activity patterns. The study was part of a national project during 2008-2010. Eligible subjects (641) were selected from a sample of 906 university students. The students wore pedometers continuously for 7 days excluding time for sleep and personal hygiene. Steps per day were logged on record sheets by each student. Data gathering spanned an entire week, and the results were sorted by alternate starting days, by activity for an entire week, by activity for only the weekdays of the one-week monitoring interval and for the two-day weekend. The statistical analysis included ANOVA, intra-class correlation (ICC) analysis, and regression analysis. The ICC analysis suggested that monitoring starting on Monday (ICC = 0.71; 95%CI (0.61-0.79)), Tuesday (ICC = 0.67; 95%CI (0.59-0.75)) or Thursday (ICC = 0.68; 95%CI (0.55-0.79)) improved reliability. The results of regression analysis also indicated that any starting day except Sunday is satisfactory as long as a minimum of four days of monitoring are used.

Abstract
This study examined the association between the presence of pedestrian and bicycle plans to pedestrian and bicyclist nonfatal and fatal injuries from 1997 to 2009 among 553 North Carolina (NC) municipalities. We considered all municipal plans (n=92; 49 pedestrian; 34 bicycle; and 9 combined plans featuring pedestrian and bicyclist components) published through 2009. Counts of pedestrian and bicyclist nonfatal and fatal injuries came from the NC Department of Transportation crash database, and the estimated number of pedestrian and bicycle trips per municipality in one year were used to calculate pedestrian and bicyclist nonfatal and fatal injury rates. In the 13-year study period, pedestrian/combined municipality plans and bicycle/combined municipality plans were present for 189 (2.6%) and 238 (3.3%) municipality-years, respectively. There were 11,795 nonfatal injuries, 9237 possible nonfatal injuries, and 1075 fatal injuries sustained by pedestrians in pedestrian-motor vehicle crashes. There were 4842 nonfatal injuries, 3666 possible nonfatal injuries, and 134 fatal injuries sustained by bicyclists in bicyclist-motor vehicle crashes. Although not statistically significant, unadjusted nonfatal and fatal injury rates among pedestrians and bicyclists were lower in those municipality-years in which plans had been published that year or in a year prior, compared to municipality-years lacking a plan. Adjusted rate ratios (RR) indicated that pedestrian nonfatal and fatal injury rates decreased in municipality-years with publication of pedestrian/combined plans (nonfatal injury RR: 0.75, 95% confidence interval (CI): 0.68, 0.82; fatal injury RR: 0.63, 95% CI: 0.46, 0.85). However, bicyclist nonfatal and fatal injury rates did not significantly change with publication of bicyclist/combined plans. Our research suggests that plan publication is associated with lower rates of nonfatal and fatal injury in pedestrians; this association was not observed for bicyclists. Further work must determine how the extent of implementation and quality of safety-related content within these plans affects changes in nonfatal and fatal injury rates.

Abstract
BACKGROUND Physical activity is considered to be one of the most important determinants of human health. Many authors emphasize the benefits of physical activity for elderly people--its positive influence on the functioning of many organs and systems, development of greater mobility, slowdown of the involution processes, and counteracting the effects of civilization diseases. OBJECTIVE The aim of this study was to analyze the structure of physical activity in older adults from the Lower Silesian region. MATERIAL AND METHOD The data was collected as part of the PolSenior national program. The subjects were selected randomly in three stages. The analysis was performed on the data from questionnaires filled out by 192 men and 164 women over the age of 65 years living in the Lower Silesian region. The answers were analyzed in categories such as: age (3 groups: 65-74 years, 75-84 years and over 85 years), gender, place of residence (communities up to 20 000 and over 20 000 inhabitants) and social-occupational status (blue-collar and white-collar workers). The survey results were shown in percentage form and concerned the different types of physical activity performed, the most frequent reasons for undertaking physical activity, sports and recreational physical activity during the respondents youth, between 30 and 60 years of age and at present, as well as the constraints and reasons that prevent an active lifestyle. RESULTS With age the percentage of people who spend their free time actively decreases. In each age group of elderly people men declared a greater need for physical activity than women. The subjects also differed with the urban factor and social-occupational status. Moreover, the results showed that the larger community, the better the condition created for recreation of older adults and the people whose previous profession was not connected with physical work tried to be physically active in various forms more often than ex-manual laborers. It is probable that education significantly influences an active attitude towards one's health and proper lifestyle. CONCLUSIONS Physical activity of seniors as a one of the basic elements of lifestyle is clearly connected with the environment in which older people live.

Integrated health impact assessment of travel behaviour: model exploration and application to a fuel price increase. ENVIRONMENT INTERNATIONAL 2013; 51:45-58.

Abstract
Transportation policy measures often aim to change travel behaviour towards more efficient transport. While these policy measures do not necessarily target health, these could have an indirect health effect. We evaluate the health impact of a policy resulting in an increase of car fuel prices by 20% on active travel, outdoor air pollution and risk of road traffic injury. An integrated modelling chain is proposed to evaluate the health impact of this policy measure. An activity-based transport model estimated movements of people, providing whereabouts and travelled kilometres. An emission- and dispersion model provided air quality levels (elemental carbon) and a road safety model provided the number of fatal and non-fatal traffic victims. We used kilometres travelled while walking or cycling to estimate the time in active travel. Differences in health effects between the current and fuel price scenario were expressed in Disability Adjusted Life Years (DALY). A 20% fuel price increase leads to an overall gain of 1650 (1010-2330) DALY. Prevented deaths lead to a total of 1450 (890-2040) Years Life Gained (YLG), with better air quality accounting for 530 (180-880) YLG, fewer road traffic injuries for 750 (590-910) YLG and active travel for 170 (120-250) YLG. Concerning morbidity, mostly road safety led to 200 (120-290) fewer Years Lived with Disability (YLD), while air quality improvement only had a minor effect on cardiovascular hospital admissions. Air quality improvement and increased active travel mainly had an impact at older age, while traffic safety mainly affected younger and middle-aged people. This modelling approach illustrates the feasibility of a comprehensive health impact assessment of changes in travel behaviour. Our results suggest that more is needed than a policy rising car fuel prices by 20% to achieve substantial health gains. While the activity-based model gives an answer on what the effect of a proposed policy is, the focus on health may make policy integration more tangible. The model can therefore add to identifying win-win situations for both transport and health.

Abstract
BACKGROUND Due to the inconsistent findings of prior studies, we explored the association of perceived safety and police-recorded crime measures with physical activity. METHODS The study included 818 Chicago participants of the Multiethnic Study of Atherosclerosis 45 to 84 years of age. Questionnaire-assessed physical activity included a) transport walking; b) leisure walking; and c) non-walking leisure activities. Perceived safety was assessed through an interviewer-administered questionnaire. Police-recorded crime was assessed through 2-year counts of selected crimes (total and outdoor incivilities, criminal offenses, homicides) per 1000 population. Associations were examined using generalized estimating equation logistic regression models. RESULTS Perceiving a safer neighborhood was positively associated with transport walking and perceiving lower violence was associated with leisure walking. Those in the lowest tertile of total or outdoor incivilities were more likely to report transport walking. Models with both perceived safety and police-recorded measures of crime as independent variables had superior fit for both transport walking and leisure walking outcomes. Neither perceived safety nor police-recorded measures of crime were associated with non-walking leisure activity. CONCLUSIONS Perceived and police-recorded measures had independent associations with walking and both should be considered in assessing the impact of neighborhood crime on physical activity.

Abstract
OBJECTIVES The aim of this study was to investigate which GIS-based measures of walkability (density, land-use mix, connectivity and walkability indexes) in urban and suburban neighbourhoods are used in research and which of them are consistently associated with walking and cycling for transport, overall active transportation and weight-related measures in adults. METHODS A systematic review of English publications using PubMed, Science Direct, Active Living Research Literature Database, the Transportation Research Information Service and reference lists was conducted. The search terms utilised were synonyms for GIS in combination with synonyms for the outcomes. RESULTS Thirty-four publications based on 19 different studies were eligible. Walkability measures such as gross population density, intersection density and walkability indexes most consistently correlated with measures of physical activity for transport. Results on weight-related measures were inconsistent. CONCLUSIONS More research is needed to determine whether walkability is an appropriate measure for predicting weight-related measures and overall active transportation. As most of the consistent correlates, gross population density, intersection density and the walkability indexes have the potential to be used in planning and monitoring.

Abstract
Using data from the 2003-2008 waves of the continuous National Health Nutrition Examination Survey merged with the 2000 census and GIS-based data, this study conducted genderspecific analyses to explore whether neighborhood built environment attributes are significant correlates of obesity risk and mediators of obesity disparities by race-ethnicity. Results indicate that the built environment is a significant correlate of obesity risk but is not much of a mediator of obesity disparities by race-ethnicity. Neighborhood walkability, density, and distance to parks are significant covariates of obesity risks net of individual and neighborhood controls. Gender differences are found for some of these associations.

Abstract
BACKGROUND The declining prevalence of Active School Transportation (AST) has been accompanied by a decrease in independent mobility internationally. The objective of this study was to compare family demographics and AST related perceptions of parents who let their children walk unescorted to/from school to those parents who escort (walk and drive) their children to/from school. By comparing these groups, insight was gained into how we may encourage greater AST and independent mobility in youth living in the Greater Toronto and Hamilton Area, Canada. METHODS This study involved a cross-sectional design, using data from a self-reported questionnaire (n =1,016) that examined parental perceptions and attitudes regarding AST. A multinomial logistic regression analysis was used to explore the differences between households where children travelled independently to school or were escorted. RESULTS Findings revealed that unescorted children were: significantly older, the families spoke predominantly English at home, more likely to live within one kilometer from school, and their parents agreed to a greater extent that they chose to reside in the current neighborhood in order for their child to walk to/from school. The parents of the escorted children worried significantly more about strangers and bullies approaching their child as well as the traffic volume around school. CONCLUSIONS From both a policy and research perspective, this study highlights the value of distinguishing between mode (i.e., walking or driving) and travel independence. For policy, our findings highlight the need for planning decisions about the siting of elementary schools to include considerations of the impact of catchment size on how children get to/from school. Given the importance of age, distance, and safety issues as significant correlates of independent mobility, research and practice should focus on the development and sustainability of non-infrastructure programs that alleviate parental safety concerns.

Abstract
OBJECTIVE To investigate if students who use of Active Transportation (AT) to and from school among urban and rural Canadian children are more likely to meet physical activity recommendations. METHODS The Raising healthy Eating and Active Living in Alberta (REAL Kids Alberta) study is a population-based health survey among Grade 5 students. In 2009, physical activity levels were measured using time-stamped pedometers (number of steps/hour) among 688 children. Parents reported mode of transportation to and from school (AT/non-AT). Multilevel multiple linear regression analyses with corresponding β coefficients were conducted to quantify the relationship between mode of transportation to and from school with (1) overall step count, and (2) the likelihood of achieving at least 13,500 steps per day recommended for optimal growth and development. RESULTS Among urban children, those who used AT to and from school accumulated more steps [β=1124(95% CI=170,2077)] and although not significant, were more likely to achieve the recommended 13,500 steps/day compared to those not using AT to and from school [OR=1.61(95% CI=0.93,2.81)]. CONCLUSION Using AT to and from school appears to be beneficial to children by supplementing their physical activity, particularly those living in urban regions. Strategies to promote physical activity are needed, particular for children residing in rural regions and smaller towns.

Abstract
BACKGROUND Numerous studies have reported that bariatric surgery patients report more physical activity (PA) after surgery than before; however, the quality of the PA assessment has been questionable. METHODS The longitudinal assessment of bariatric surgery-2 is a 10-center longitudinal study of adults undergoing bariatric surgery. Of 2458 participants, 455 were given an activity monitor, which records the steps per minute, and an exercise diary before and 1 year after surgery. The mean number of steps/d, active min/d, and high-cadence min/wk were calculated for 310 participants who wore the monitor ≥10 hr/d for ≥3 days at both evaluations. Pre- and postoperative PA were compared for differences using the Wilcoxon signed-rank test. Generalized estimating equations were used to identify independent preoperative predictors of postoperative PA. RESULTS PA increased significantly (P < .0001) from before to after surgery for all PA measures. The median values before and after surgery were 7563 and 8788 steps/d, 309 and 340 active min/d, and 72 and 112 high-cadence min/wk, respectively. However, depending on the PA measure, 24-29% of participants were ≥5% less active postoperatively than preoperatively. Controlling for surgical procedure, gender, age, and body mass index, more PA preoperatively independently predicted for more PA postoperatively (P < .0001, for all PA measures). Less pain, not having asthma, and the self-report of increasing PA as a weight loss strategy preoperatively also independently predicted for more high-cadence min/wk postoperatively (P < .05). CONCLUSIONS The majority of adults increase their PA level after bariatric surgery. However, most remain insufficiently active, and some become less active. Increasing PA, addressing pain, and treating asthma before surgery might have a positive effect on postoperative PA.
