Purpose: To explore the effects of targeted physical activity (PA) print material on PA and quality of life (QOL) in young adult cancer survivors (YACS) aged 18-39 either on or off treatment. Methods: YACS ( N=212) recruited from a cancer registry were randomly assigned to a Targeted Physical Activity Guidebook (TPAG) or the Canadian Physical Activity Guidelines (CPAG). An online or mailed survey assessed the primary outcome of self-reported PA minutes and secondary QOL outcomes. Assessments were conducted at baseline, 1 month, and 3 months for PA and at baseline and 3 months for QOL. Results: At 3 months, analyses of covariance showed no differences between the groups for the primary outcome of PA minutes/week (adjusted mean group difference=+8 minutes; 95% confidence interval [CI]: −60 to +77; p=0.81). The TPAG was superior to the CPAG for the mental component of QOL (adjusted mean group difference=+3.1; 95% CI: +0.1 to +7.3; p=0.043). In an exploratory analysis of YACS reporting ≤300 PA minutes/week at baseline ( N=108), the TPAG group was superior to the CPAG group at 3 months for PA minutes/week (adjusted mean group difference=+90; 95% CI: +10 to +170; p=0.028). Conclusion: Targeted PA print material did not increase PA compared to generic PA print material in a highly active sample of YACS. In YACS reporting ≤300 PA minutes/week at baseline-the group of interest from a PA behavior change perspective-the targeted PA print material was effective in increasing PA. [ABSTRACT FROM AUTHOR]

Aim: This study examined adolescent nutrition behaviours and associations with a range of adolescent and parent characteristics to underpin the development of key objectives for focus in the development of school-based interventions for the prevention of adolescent overweight/obesity. Methods: Three hundred and sixty-two adolescents from six secondary schools completed questionnaires regarding their nutrition behaviours, physical activity and sedentary activities, and 349 parents completed questionnaires to report their height and body weight, nutrition behaviours, physical activity, and values of adolescent obesity-related behaviours. Adolescent height and body weight were objectively measured for calculation of body mass index. Logistic regression ( P < 0.05) and Pearson chi-square analyses of 295 matched adolescent and parent questionnaires were conducted to examine associations. Results: Adolescent healthy nutrition behaviours were negatively associated with time spent in small screen recreation (odds ratio 0.48, P= 0.02) and positively associated with time spent in sedentary education (odds ratio 2.44, P= 0.004) and physical activity (odds ratio 2.53, P= 0.03). Gender differences were found. No associations were found between adolescent healthy nutrition behaviours and adolescent body mass index, parent body mass index, parent nutrition behaviours or parent values of adolescent health behaviours. Conclusions: Interventions to promote adolescent healthy nutrition behaviours should be gender-specific and include action around a range of obesity-related health behaviours including physical activity and time spent in small screen recreation.

Background: Continued low adherence to physical activity recommendations illustrates the need to refine intervention strategies and increase their effectiveness. The purpose of this study was to conduct formative research related to the development of a next generation of computer-tailored interventions that use online tailored video-messages to increase physical activity. Methods: Five focus groups (n = 30), aimed at males and females, aged between 35 and 60 years, that do not meet the physical activity recommendation, were conducted to allow in-depth discussion of various elements related to the development of an online video-tailored intervention. In addition, a series of questions were delivered to a random sample (n = 1261) of Australians, using CATI survey technology, to gain more information and add a quantitative assessment of feasibility related to the development of the intervention. Focus group data was transcribed, and summarised using Nvivo software. Descriptive and frequency data of the survey was obtained using SPSS 18.0. Results: Nearly all of the focus group participants supported the concept of a video-tailored intervention and 35.8% of survey participants indicated that they would prefer a video-based over a text-based intervention. Participants with a slow internet-connection displayed a lower preference for video-based advice (31.9%); however less than 20% of the survey sample indicated that downloading videos would be slow. The majority of focus group and survey participants did not support the idea of using mobile phones to receive this kind of intervention and indicated that video-tailored messages should be shorter than 5 minutes. Video-delivery of content is very rich in information, which increases the challenge to appropriately tailor content to participant characteristics; focusgroup outcomes indicated a large diversity in participant preferences. 52.4% of survey participants indicated that the videos should be convincing and motivating. Conclusions: These results provide valuable information to develop an innovative video-tailored physical activity intervention. The results support the feasibility of such intervention, both in terms of users being ready to participate in it, as well as from a point of view whereby current internet infrastructure is able to cope with the demands of downloading videos. Though promising, a number of specific challenges in the development of these interventions were identified (e.g. the videos need to be short, made professionally, and tailor to a larger number of variables) and will need to be overcome in the development and evaluation of this new type of physical activity intervention.

Objective The purpose of the present study was to conduct a process analysis of the effects of personality on physical activity intention and behaviour using the theory of planned behaviour (TPB). Design Prospective study design with data collected by means of two questionnaires. Methods Data were obtained by means of two questionnaires, the initial questionnaire measured demographic characteristics, TPB constructs, physical activity intention and personality. The 2-week follow-up questionnaire assessed self-report physical activity behaviour. A series of regression analysis were undertaken to identify the relationship between the variables and to determine mediation effects of the TPB constructs. Patients A random sample of individuals with type II diabetes was selected from the Diabetes Australia (Queensland) membership database. A total of 74 complete data sets were obtained. Results Intention explained 28% of the variance in physical activity behaviour. Attitude, subjective norm and perceived behavioural control (PBC) explained 73% of variance in physical activity intention. Attitude and PBC mediated the relationship between conscientiousness and physical activity intention. Conclusions These results provide preliminary evidence that targeting constructs proximal to the behaviour (attitudes and PBC) may be effective in overcoming inherent qualities such as personality in order to produce physical activity behaviour change within this sample population.

The article discusses Australia's Women’s Active Living Kits (WALK) Community Grant Scheme, which is a federally-funded initiative for the promotion and engagement of women's groups in health-related physical activity. Topics include an overview of WALK, which provided small grants to support the development of women's walking groups, the challenges and barriers throughout the grant program process, and insights for replicating the initiative.

Abstract: This study examines how physical activity and perceptions of the built environment differ by degree of urbanisation in Queensland, Australia. A statewide sample of adults (n=1208) completed a CATI survey assessing physical activity and perceptions of the environment in July–August 2005. Results indicate that residents in metropolitan areas were more likely to report the presence of shops and services, footpaths, heavy traffic and physical activity facilities than non-metropolitan residents. Although geographic location was not associated with achievement of sufficient levels of physical activity or walking, a notable interaction in the associations between both physical activity measures and the presence of footpaths in metropolitan and non-metropolitan areas was observed. This finding suggests the presence of a differential mechanism in terms of the relationships between physical activity and environmental supports by geographical location. Such effects require future investigation in terms of replication and understanding. [Copyright &y& Elsevier]

The article determines the test-retest reliability of global positioning system (GPS) units for measuring distance traveled when doing physical activities such as walking and cycling and to know whether the GPS unit placement influences its accuracy. The authors asked the participants to complete two walking and cycling trials at self-selected speeds wearing two Garmin GPS units in lanyard and wristband placements. They saw no significant differences observed between trials. They also implied that the lanyard position is the best placement for units during the collection of data.

The purpose of this study was to examine the extent to which physical activity among adolescent female friends is interdependent. The participants were 318 adolescent girls with a mean age of 16.0 years (range: 15-18 years). Pedometry was used to assess physical activity over 4 days. The relationship between an individual girl and her first-nominated reciprocal friend's physical activity level was moderate (r = 0.45, 90% confidence interval = 0.31, 0.56), when the friendship was nonreciprocal it was trivial (r = -.06, 90% confidence interval = -.36. .25). Friends' physical activity levels explained between 27% and 32% of an individual's pedometer-determined physical activity level. Reciprocity of friendship is an important variable to consider when understanding the relationship between adolescent female friends' physical activity. Wizen friendships are reciprocal, there is a stronger relationship between friends' physical activity. [ABSTRACT FROM AUTHOR]

Background: One of the major immediate and long-term health issues in modern society is the problem of overweight and obesity. This paper examines the role of the workplace in the problem by studying the association between occupational sitting time and overweight and obesity (body mass index [BMI] ≥25) in a sample of adult Australians in full-time employment. Methods: Data on age, gender, occupation, physical activity, occupational sitting time, and BMI were collected in September 2003 from a sample of 1579 adult men and women in full-time employment at the time of the survey. Logistic regression was used to examine the association between occupational sitting time and overweight and obesity. Results: Mean occupational sitting time was >3 hours/day, and significantly higher in men (209 minutes) than in women (189 minutes, p=0.026). Univariate analyses showed significant associations between occupational sitting time and BMI of ≥25 in men but not in women. After adjusting for age, occupation, and physical activity, the odds ratio for BMI ≥25 was 1.92 (confidence interval: 1.17–3.17) in men who reported sitting for >6 hours/day, compared with those who sat for &#60;45 minutes/day. Conclusions: Occupational sitting time was independently associated with overweight and obesity in men who were in full-time paid work. These results suggest that the workplace may play an important role in the growing problem of overweight and obesity. Further research is needed to clearly understand the association between sitting time at work and overweight and obesity in women. [Copyright &y& Elsevier]

Introduction: Current methods of assessing routes taken during active transport rely on subjective recall of trip length and barriers encountered enroute or the utilization of objective measures (Geographic Information Systems –[GIS]) that may not represent actual travel patterns. This study examined the utility of Global Positioning Systems (GPS) to measure actual routes taken compared with GIS-estimated travel distance and barriers encountered. Methods: Comparisons between GPS and GIS routes were performed for 59 of 75 children who wore a GPS during the journey to school on a single occasion. Home and school addresses were reported by parents and geocoded in GIS. Children were provided with a GPS and were instructed to travel their normal route to and from school. Data were collected between March and November 2005 and exported to the GIS to determine travel distance, number of busy streets crossed, and the ratio of busy streets to the total streets traveled on. Data analysis was performed in August 2006. Results: No differences were observed between GPS-measured journeys to and from school on any of the examined variables. No differences were observed between GIS and GPS measures of travel distance (p>0.05). GIS-estimated travel routes crossed a significantly (p<0.05) higher number of busy streets (GIS: 1.68±0.12 vs GPS: 1.19±0.11) and traveled on a higher ratio of busy streets to total streets traveled on (GIS: 0.46±0.03 vs GPS: 0.35±0.04) (p<0.05) compared with GPS-measured actual travel routes. Conclusions: Geographic Information Systems provides estimates of travel distance similar to GPS-measured actual travel distances. Travel routes estimated by GIS are not representative of actual routes measured by GPS, which indicates that GIS may not provide an accurate estimate of barriers encountered. The continued use of GPS in active transport research in encouraged. [Copyright &y& Elsevier]

Background: Dog ownership has been associated with higher rates of physical activity (PA) in several populations but no study to date has focused on cancer survivors. The purpose of this study was to examine the associations between dog ownership and PA among cancer survivors and to examine correlates of dog ownership.Methods: A stratified random sample of 2062 breast cancer survivors, prostate cancer survivors, and colorectal cancer survivors was mailed a questionnaire assessing PA, social cognitive, dog ownership, demographic, and medical variables.Results: Overall, 25% of the sample was dog owners (DOs). There were no significant differences in moderate, vigorous, or total PA minutes between DOs and non-dog owners. There was a significant difference in light PA minutes in favor of DOs (153 vs 112 minutes; 95% CI = 4 to 77; P = .030), however, this was largely restricted to breast cancer survivors (143 vs 79 minutes; 95% CI = 25 to 102; P = .001) who also reported fewer vigorous PA minutes (18 vs 39 minutes; 95% CI = -42 to -1; P = .042). Survivors were more likely to be DOs if they had breast cancer (P = .054), a higher income (P = .021), radiation therapy (P = .029), chemotherapy (P = .010), were younger (P < .001), employed (P < .001), and a current smoker (P = .015). Few social cognitive variables were associated with DO.Conclusions: Dog ownership among cancer survivors was not associated with moderate-to-vigorous PA but was associated with light PA. Further research is necessary to determine if promoting dog ownership and dog walking among cancer survivors may increase PA and possibly improve health outcomes. [ABSTRACT FROM AUTHOR]

Objective:To examine the effects of an internet-delivered, distance-based physical activity (PA) behaviour change programme on motivation to perform PA in cancer survivors. Design:Breast, prostate and colorectal cancer survivors (N = 95) were randomized to either an online Theory of Planned Behaviour (TPB)-based PA behaviour change programme (UCAN) or usual care. Main Outcome Measures:Motivational variables from the TPB including intention, planning, attitude, subjective norm, perceived behavioural control and underlying beliefs. Results:UCAN had significant negative effects on self-efficacy (−.7; 95% CI = −1.2 to −.1;d =−.53,p =.019), affective attitude (−.4; 95% CI = −.8 to −.0;d =−.45,p =.044), instrumental attitude (−.5; 95% CI = −.9 to −.1;d =−.43,p =.026) and confidence to perform PA in bad weather (−.8; 95% CI = −1.6 to −.1;d =−.49,p =.030), despite health issues (−.7; 95% CI = −1.3 to −.1;d =−.48,p =.031), despite pain/soreness (−.7; 95% CI = −1.4 to −.1;d =−.52,p =.020), despite family responsibilities (−1.0; 95% CI = −1.7 to −.3;d =−.62,p =.005) and when PA is boring (−.8; 95% CI = −1.4 to −.1;d =−.54,p =.016). Conclusion:UCAN had negative effects on motivational variables in cancer survivors. These findings may be explained by methodological issues related to measuring motivation and/or the absence of post-intentional constructs. [ABSTRACT FROM PUBLISHER]

Background: Pedometer-facilitated interventions encourage physical activity via the accumulation of steps. Mixed evidence suggests that neighborhood walkability might influence the effectiveness of physical activity interventions, including pedometer-facilitated interventions. Our study investigated the moderating effect of neighborhood walkability on immediate (4-week) and short-term (12-week) changes in self-reported neighborhood-specific leisure and transportation walking, leisure-based moderate and vigorous-intensity physical activity, and leisure-based screen time during a pedometer-facilitated intervention (UWALK). Methods: This quasi-experiment undertaken in Calgary (Canada) compared behavior changes during the 12-week intervention between two neighborhood groups classified as 'walkable' or 'car dependent' based on Walk Score®. Of the 573 volunteers (adults in the contemplation and preparation stages of physical activity behavior change), 466 participated in UWALK. Surveys captured sociodemographic characteristics, perceived neighborhood walkability, neighborhood preferences, motivation, physical activity and screen-based leisure. Covariate-adjusted linear mixed models estimated the differences in physical activity and leisure screen time between the neighborhood walkability groups at baseline, 4-weeks, and 12-weeks. Results: UWALK participants included mostly females (83%) and had an average age of 49.2 years. Weekly minutes of walking for transport inside the neighborhood was higher (p <.001) among participants from walkable versus car dependent neighborhoods at baseline (42.5 vs. 21.1), 4-weeks (81.2 vs. 48.2), and 12-weeks (87.2 vs. 48.0). Regardless of neighborhood walkability, all physical activity outcomes were higher and leisure screen time lower at 4-weeks and 12-weeks compared with baseline. We found no significant neighborhood group by time interactions. Conclusions: Pedometer-facilitated interventions may be effective for supporting short-term changes in physical activity and sedentary behavior even among adults residing in low walkable neighborhoods.

: Strong evidence exists for the role of physical activity in preventing and managing a range of chronic health conditions. A particular challenge in promoting physical activity as a health strategy exists in culturally and linguistically diverse (CALD) groups, as such groups demonstrate high risk for a range of non-communicable diseases. The aim of this research was to examine the perspective of multicultural health service providers for CALD groups with respect to the physical activity services/initiatives on offer, access barriers to these services, and ideas for future service delivery in this area. Semi-structured interviews were conducted with 15 multicultural health service providers across the capital cities of the three most populous states in Australia (New South Wales, Queensland, and Victoria), and thematic content analysis was used to examine the data. Findings indicated that the majority of physical activity initiatives were associated with organizations offering other social services for CALD communities but were greatly restrained by resources. As well, it was found that most services were not designed by taking into account specific cultural requirements for CALD communities or their cultural expectations. Common barriers identified to service uptake were classified as socio-cultural (e.g., gender, language, context of health) and environmental (e.g., transportation) in nature. These findings should be utilized when planning future physical activity and health promotion initiatives for increasing CALD participation. In particular, programs need to be culturally tailored to the specific expectations of CALD groups, addressing cultural safety and sensitivity, and should be in partnership with other organizations to extend the reach and capacity.

A close examination of epidemiological data reveals burdens of disease particular to culturally and linguistically diverse (CALD) migrants, as these individuals adjust to both culture and modernization gaps. Despite theincreased risk of hypertension, diabetes mellitus, overweight/obesity and cardiovascular disease, individuals from CALD groups are less likely to be proactive in accessing healthcare or undertaking preventative measures to ensure optimal health outcomes. The purpose of this paper is to review literature that outlines the barriers, challenges and enablers of physical activity in CALD groups who have recently migrated to Western society, and to identify key strategies to increase physical activity participation for these individuals. Electronic and manual literature searches were used to identify 57 publications that met the inclusion criteria. Findings from the review indicate that migration to Western societies has a detrimental effect on the health status and health behaviours of CALD groups as they assimilate to their new surroundings, explore different cultures and customs, and embrace a new way of life. In particular, there is evidence that physical inactivity is common in migrant CALD groups, and is a key contributing risk factor to chronic disease for these individuals. Challenges and barriers that limit physical activity participation in CALD groups include: cultural and religious beliefs, issues with social relationships, socioeconomic challenges, environmental barriers, and perceptions of health and injury. Strategies that may assist with overcoming these challenges and barriers consist of the need for cultural sensitivity, the provision of education sessions addressing health behaviours, encouraging participation of individuals from the same culture, exploration of employment situational variables, and the implementation of 'Health Action Zones' in CALD communities. This information will inform and support the development of culturally appropriate programmes designed to positively influence the physical activity behaviours of individuals from CALD populations.

Abstract: Objectives: This study examines how engagement in transport-related physical activity (TPA), perceptions of the commute route, actual travel distance, and perceptions of travel distance vary by degree of urbanization in rural and remote areas of Central Queensland, Australia. Method: A random, cross-sectional sample of 1230 adults aged 18 years and over residing in rural and remote Central Queensland were surveyed by telephone in October–November 2006. Engagement in and attitudes towards TPA, perceptions of the commute route, actual travel distances, and perceived appropriate travel distances for TPA were assessed. Results: For this study 765 adults were eligible for the analysis as they traveled to an occupation. Overall, 86% of the sample commuted to their occupation by motorized modes, 71% of individuals recognized 5 km or less as an appropriate distance to travel via TPA modes, and 45% of respondents reported travel distances less than five kilometers (km) to reach their workplace. Participants from small rural and remote settings more frequently traveled greater than 20 km to reach their occupation, reported fewer sidewalks and shops, and less heavy traffic enroute compared to respondents in large rural settings. Conclusion: Infrastructure for, and participation in TPA varies according to degree of urbanization. Future work in this area should target the substantial population that recognizes they could engage in TPA. As such, increasing TPA participation in these settings likely requires a cultural shift and infrastructure improvements. [Copyright &y& Elsevier]

Background: Several narrative reviews have been conducted on the literature examining environmental correlates of physical activity (PA). To date these reviews have been unable to provide definitive summaries of observed associations. This study utilizes meta-analytical techniques to calculate summaries of associations between selected environmental characteristics and PA. Methods: Published studies were identified from electronic databases and searches of personal files. Studies were examined to determine the environmental constructs most frequently studied. Included studies (N = 16) examined at least one identified construct and determined associations between perceived environmental constructs and PA using logistic regression. Data were analyzed separately for crude and adjusted ORs using general-variance based fixed effect models. Results: No significant associations emerged between environmental characteristics and PA using crude OR. The perceived presence of PA facilities (OR 1.20, 95% 1.06-1.34), sidewalks (OR 1.23, 95% 1.13-1.32), shops and services (OR 1.30, 95% 1.14-1.46) and perceiving traffic not to be a problem (OR 1.22, 95% 1.08-1.37) were positively associated with activity using adjusted ORs. Variance in PA accounted for by significant associations ranged from 4% (heavy traffic not a problem) to 7% (presence of shops and services). Conclusion: Results of the meta-analysis support the relevance of perceived environmental characteristics for understanding population PA. These results should encourage the use of comprehensive ecological models that incorporate variables beyond basic demographic information. [ABSTRACT FROM AUTHOR]

Objectives: This study examined the impact of the COVID‐19 lockdown on the physical activity (PA) of UK adults and potential motivational determinants of such behaviour. Design and methods: A survey was conducted with 1,521 UK adults recruited through Prolific.co in early June 2020. Along with demographic information, questions assessed current PA, changes in PA modalities (i.e., overall, around the home, for transport, in the workplace, in the local neighbourhood, at recreation/sport facilities) related to the lockdown, and beliefs about capabilities, opportunities, and motivations according to the COM‐B model. A series of logistic regressions were constructed to examine associations between shifts in the PA modalities and the COM‐B components. Results: The majority of respondents (57%) had either maintained or increased their levels of PA during the COVID‐19 lockdown. However, the proportion meeting PA guidelines (31%) was low and engagement in sedentary‐related behaviour for both work and leisure increased substantially during the lockdown. The components of the COM‐B model were associated with shifts in PA. In particular, physical opportunity (odds ratios ranging from 1.14 to 1.20) and reflective motivation (odds ratios ranging from 1.11 to 1.25) appeared to be the most consistent predictors of behaviour. Conclusions: If UK adults believed they had the physical opportunity and were motivated, they were more likely to have maintained or increased their PA during the COVID‐19 lockdown. However, the majority of adults are not meeting the UK guidelines on PA and the prevalence of PA is substantially lower than national surveys prior to the pandemic. Statement of contributionWhat is already known on this subject?The COVID‐19 pandemic has significantly disrupted the daily routines of citizens globally.Engagement in physical activity appears to have declined as a result of the requirement to self‐isolate and stay in place.The COM‐B model of behaviour change is a useful framework for identifying the correlates and determinants of behaviour.What does this study add?Though most UK adults maintained or increased their engagement in physical activity during the COVID‐19 pandemic, the majority did not meet recommended guidelines.Reflective processes and physical opportunity were the primary predictors of change in physical activity.

While physical and mental health benefits of regular physical activity are well known, increasing evidence suggests that limiting sedentary behaviour is also important for health. Evidence shows associations of physical activity and sedentary behaviour with health-related quality of life (HRQoL), however, these findings are based predominantly on duration measures of physical activity and sedentary behaviour (e.g., minutes/week), with less attention on frequency measures (e.g., number of bouts). We examined the association of HRQoL with physical activity and sedentary behaviour, using both continuous duration (average daily minutes) and frequency (average daily bouts≥10 min) measures. Baseline data from the WALK 2.0 trial were analysed. WALK 2.0 is a randomised controlled trial investigating the effects of Web 2.0 applications on engagement, retention, and subsequent physical activity change. Daily physical activity and sedentary behaviour (duration = average minutes, frequency = average number of bouts ≥10 minutes) were measured (ActiGraph GT3X) across one week, and HRQoL was assessed with the ‘general health’ subscale of the RAND 36-Item Health Survey. Structural equation modelling was used to evaluate associations. Participants (N = 504) were 50.8±13.1 (mean±SD) years old with a BMI of 29.3±6.0. The 465 participants with valid accelerometer data engaged in an average of 24.0±18.3 minutes and 0.64±0.74 bouts of moderate-vigorous physical activity per day, 535.2±83.8 minutes and 17.0±3.4 bouts of sedentary behaviour per day, and reported moderate-high general HRQoL (64.5±20.0). After adjusting for covariates, the duration measures of physical activity (path correlation = 0.294, p<0.05) and sedentary behaviour were related to general HRQoL (path coefficient = -0.217, p<0.05). The frequency measure of physical activity was also significant (path coefficient = -0.226, p<0.05) but the frequency of sedentary behaviour was not significantly associated with general HRQoL. Higher duration levels of physical activity in fewer bouts, and lower duration of sedentary behaviour are associated with better general HRQoL. Further prospective studies are required to investigate these associations in different population groups over time. [ABSTRACT FROM AUTHOR]

Context: Stair climbing is an accessible activity that can be incorporated into one's daily lifestyle to increase physical activity levels and provide health benefits. This review summarizes the effectiveness of stair interventions and explores key differences that may influence intervention effectiveness.Evidence Acquisition: Interventions to increase stair use published from January 1990 to July 2015 were identified in PubMed, Sport Discus, Web of Science, Environment Complete, CINAHL, Trial Register of Promoting Health Interventions, Embase, Scopus, and PsycINFO. Eligibility criteria included original studies, published in peer-reviewed journals, targeting adult samples, and clearly describing intervention design and results. Studies were also required to measure the use of stairs compared with an elevator, escalator, or moving stairway at baseline and during at least one timepoint when the intervention was in effect. Studies were required to provide data to determine if the intervention resulted in significant changes in stair use/climbing.Evidence Synthesis: The search results yielded 2,136 articles in total; 54 articles met the criteria, which resulted in a final sample of 67 studies included in the analyses. Interventions settings included public sites (75%), worksites (21%), or a combination of both (4%). For Phase 1 results, 72% of studies reported significant improvements in stair use (n=10 of 14) and stair climbing (n=38 of 53).Conclusions: Evidence from the review demonstrates support for the effectiveness of interventions to increase stair use and stair climbing. Although evidence supports the effectiveness of stair interventions in public settings, less support is provided for worksites. [ABSTRACT FROM AUTHOR]

Background: Requiring individuals to obtain medical clearance to exercise prior to participation in physical activity interventions is common. The impact this has on the socio-demographic characteristic profiles of participants who end up participating in the intervention is not clear. Methods: As part of the multi-component eligibility screening for inclusion in a three-arm randomised controlled trial examining the efficacy of a web-based physical activity intervention, individuals interested in participating were required to complete the Physical Activity Readiness Questionnaire (PAR-Q). The PAR-Q identified individuals as having lower or higher risk. Higher-risk individuals were required to obtain medical exercise clearance prior to enrolment. Comparisons of the socio-demographic characteristics of the lower- and higher-risk individuals were performed using t tests and chi-square tests (p = 0.05). Results: A total of 1244 individuals expressed interest in participating, and 432 were enrolled without needing to undergo further screening. Of the 251 individuals required to obtain medical clearance, 148 received clearance, 15 did not receive clearance and 88 did not return any form of clearance. A total of 105 individuals were enrolled after obtaining clearance, and the most frequent reason for being required to seek clearance was for using blood pressure/heart condition medication. Higher-risk individuals were significantly older, had a higher body mass index and engaged in more sedentary behaviour than lower-risk individuals. Conclusions: Use of more inclusive participant screening protocols that maintain high levels of participant safety are encouraged. Allowing individuals to obtain medical clearance to participate can result in including a more diverse population likely to benefit most from participation. [ABSTRACT FROM AUTHOR]

Translating evidence-based interventions into community practice is vital to health promotion. This study used the RE-AIM framework to evaluate the larger dissemination of the ManUp intervention, an intervention which utilized interactive web-based technologies to improve the physical activity and nutrition behaviors of residents in Central Queensland, Australia. Data were collected for each RE-AIM measure (Reach, Effectiveness, Adoption, Implementation, Maintenance) using (i) computer-assisted telephone interview survey (N=312) with adults (18years and over) from Central Queensland, (ii) interviews with key stakeholders from local organizations (n= 12) and (iii) examination of project-related statistics and findings. In terms of Reach, 47% of participants were aware of the intervention; Effectiveness, there were no significant differences between physical activity and healthy nutrition levels in those aware and unaware; Adoption, 73 participants registered for the intervention and 25% of organizations adopted some part of the intervention; Implementation, 26% of participants initially logged onto the website, 29 and 17% started the web-based physical activity and nutrition challenges, 33% of organizations implemented the intervention, 42% considered implementation and 25% reported difficulties; Maintenance, an average of 0.57 logins and 1.35 entries per week during the 12 week dissemination and 0.27 logins and 0.63 entries per week during the 9-month follow-up were achieved, 22 and 0% of participants completed the web-based physical activity and nutrition challenges and 33.3% of organizations intended to continue utilizing components of the intervention. While this intervention demonstrated good reach, effectiveness, adoption and implementation warrant further investigation. [ABSTRACT FROM AUTHOR]

Background: Physical activity (PA) offers numerous benefits to health and well-being, but most adults are not sufficiently physically active to afford such benefits. The 10,000 steps campaign has been a popular and effective approach to promote PA. The Transtheoretical Model posits that individuals have varying levels of readiness for health behavior change, known as Stages of Change (Precontemplation, Contemplation, Preparation, Action, and Maintenance). Few validated assessment instruments are available for determining Stages of Change in relation to the PA goal of 10,000 steps per day. The purpose of this study was to assess the criterion-related validity of the SoC-Step, a brief 10,000 steps per day Stages of Change instrument.Methods: Participants were 504 Australian adults (176 males, 328 females, mean age = 50.8 ± 13.0 years) from the baseline sample of the Walk 2.0 randomized controlled trial. Measures included 7-day accelerometry (Actigraph GT3X), height, weight, and self-reported intention, self-efficacy, and SoC-Step: Stages of Change relative to achieving 10,000 steps per day. Kruskal-Wallis H tests with pairwise comparisons were used to determine whether participants differed by stage, according to steps per day, general health, body mass index, intention, and self-efficacy to achieve 10,000 steps per day. Binary logistic regression was used to test the hypothesis that participants in Maintenance or Action stages would have greater likelihood of meeting the 10,000 steps goal, in comparison to participants in the other three stages.Results: Consistent with study hypotheses, participants in Precontemplation had significantly lower intention scores than those in Contemplation (p = 0.003) or Preparation (p < 0.001). Participants in Action or Maintenance stages were more likely to achieve ≥10,000 steps per day (OR = 3.11; 95 % CI = 1.66,5.83) compared to those in Precontemplation, Contemplation, or Preparation. Intention (p < 0.001) and self-efficacy (p < 0.001) to achieve 10,000 steps daily differed by stage, and participants in the Maintenance stage had higher general health status and lower body mass index than those in Precontemplation, Contemplation and Preparation stages (p < 0.05).Conclusions: This brief SoC-Step instrument appears to have good criterion-related validity for determining Stages of Change related to the public health goal of 10,000 steps per day.Trial Registration: Australian New Zealand Clinical Trials Registry reference: ACTRN12611000157976 World Health Organization Universal Trial Number: U111-1119-1755.

OBJECTIVE: This study examined the effectiveness of a fully automated web-based programme to increase physical activity in adults with Type 2 diabetes. METHODS: Between May and July 2010, participants were randomly allocated into either a 12-week intervention (n=195) or a control (n=202) group. Participants were adults diagnosed with Type 2 diabetes, residing in Australia. Participants were assessed at baseline, 12 and 36weeks. The primary physical activity outcome was self-reported minutes of total physical activity. Secondary physical activity outcomes included minutes spent walking, and engaged in moderate, and vigorous physical activity. Additional measures included website satisfaction and website usage. The intervention consisted of a 12-week web-based physical activity intervention developed based on the Theory of Planned Behavior and self-management framework. Data were analysed from 2011 to 2012. RESULTS: There was a significant group-by-time interaction (X(2) (df=1)=6.37, p<.05) for total physical activity favouring the intervention group d=0.11, for those who completed the intervention, however this was not significant in the intention-to-treat analysis d=0.01. The intervention yielded high website satisfaction and usage. CONCLUSIONS: In general, there is some evidence for the effectiveness of web-based interventions for improving physical activity levels; however it is clear that maintaining improvements remains an issue.

Background: Interventions that facilitate access to cardiac rehabilitation and secondary prevention programs are in demand. Methods: This pilot study used a mixed methods design to evaluate the feasibility of an Internet-based, electronic Outpatient Cardiac Rehabilitation (eOCR). Patients who had suffered a cardiac event and their case managers were recruited from rural primary practices. Feasibility was evaluated in terms of the number of patients enrolled and patient and case manager engagement with the eOCR website. Results: Four rural general practices, 16 health professionals (cardiologists, general practitioners, nurses and allied health) and 24 patients participated in the project and 11 (46%) completed the program. Utilisation of the website during the 105 day evaluation period by participating health professionals was moderate to low (mean of 8.25 logins, range 0–28 logins). The mean login rate for patients was 16 (range 1–77 logins), mean time from first login to last (days using the website) was 51 (range 1–105 days). Each patient monitored at least five risk factors and read at least one of the secondary prevention articles. There was low utilisation of other tools such as weekly workbooks and discussion boards. Conclusions: It was important to evaluate how an eOCR website would be used within an existing healthcare setting. These results will help to guide the implementation of future internet based cardiac rehabilitation programs considering barriers such as access and appropriate target groups of participants.

Background: Energy excess, low fruit and vegetable intake and other suboptimal dietary habits contribute to an increased poor health and the burden of disease in males. However the best way to engage males into nutrition programs remains unclear. This review provides a critical evaluation of the nature and effectiveness of nutrition interventions that target the adult male population. Methods: A search for full-text publications was conducted using The Cochrane Library; Web of Science; SCOPUS; MEDLINE and CINAHL. Studies were included if 1) published from January 1990 to August 2011 and 2) male only studies (≥18 years) or 3) where males contributed to >90% of the active cohort. A study must have described, (i) a significant change (p<0.05) over time in an objective measure of body weight, expressed in kilograms (kg) OR Body Mass Index (BMI) OR (ii) at least one significant change (p<0.05) in a dietary intake measure to qualify as effective. To identify emerging patterns within the research a descriptive process was used. Results: Nine studies were included. Sample sizes ranged from 53 to 5042 male participants, with study durations ranging from 12 weeks to 24 months. Overlap was seen with eight of the nine studies including a weight management component whilst six studies focused on achieving changes in dietary intake patterns relating to modifications of fruit, vegetable, dairy and total fat intakes and three studies primarily focused on achieving weight loss through caloric restriction. Intervention effectiveness was identified for seven of the nine studies. Five studies reported significant positive changes in weight (kg) and/or BMI (kg/m2) changes (p≤0.05). Four studies had effective interventions (p<0.05) targeting determinants of dietary intake and dietary behaviours and/or nutritional intake. Intervention features, which appeared to be associated with better outcomes, include the delivery of quantitative information on diet and the use of self-monitoring and tailored feedback. Conclusion: Uncertainty remains as to the features of successful nutrition interventions for males due to limited details provided for nutrition intervention protocols, variability in mode of delivery and comparisons between delivery modes as well as content of information provided to participants between studies. This review offers knowledge to guide researchers in making informed decisions on how to best utilise resources in interventions to engage adult males while highlighting the need for improved reporting of intervention protocols.

Physical inactivity is one of the main modifiable risk factors for a range of noncommunicable diseases. Of particular interest are adult males, a hard-to-reach population group for health promotion interventions. The purpose of this review is to provide a critical evaluation of the published health-related physical activity interventions that have targeted adult males. A comprehensive search of MEDLINE, CINAHL®, ScienceDirect, Web of Science, PsycINFO, the Cochrane Library, and SPORTDiscus™ was conducted for intervention studies published in English, between January 1990 and August 2010. Studies including community-dwelling adult men (⩾18 years), or including both males and females where data on male participants could be extracted and examined, were included in this review. Studies assessing changes in levels of physical activity, physical fitness or changes in biomarkers of disease risk relevant to physical activity (e.g. body weight, waist circumference, lipids, blood pressure) were the primary focus. A total of 14 studies focusing on physical activity only and nine combined physical activity and nutrition studies were also included in this review. Ten of the 14 physical activity only studies and four of the nine combined physical activity and nutrition studies demonstrated significant increases in physical activity outcomes. Face-to-face, group-based and print-based methods were most commonly employed in these interventions. Within each mode of delivery, a number of elements including regular feedback, access to self-monitoring tools, elements of social support, variety in activities and a degree of friendly competition, were revealed as positive inclusions for this population group. Males are generally under-represented in health-promotion interventions and should therefore be targeted specifically, and while results of the included studies are encouraging, there is a lack of intervention studies targeting adult males. Further research into this population group is therefore required. [ABSTRACT FROM AUTHOR]

Many internet-delivered physical activity behaviour change programs have been developed and evaluated. However, further evidence is required to ascertain the overall effectiveness of such interventions. The objective of the present review was to evaluate the effectiveness of internet-delivered interventions to increase physical activity, whilst also examining the effect of intervention moderators. A systematic search strategy identified relevant studies published in the English-language from Pubmed, Proquest, Scopus, PsychINFO, CINHAL, and Sport Discuss (January 1990--June 2011). Eligible studies were required to include an internet-delivered intervention, target an adult population, measure and target physical activity as an outcome variable, and include a comparison group that did not receive internet-delivered materials. Studies were coded independently by two investigators. Overall effect sizes were combined based on the fixed effect model. Homogeneity and subsequent exploratory moderator analysis was undertaken. A total of 34 articles were identified for inclusion. The overall mean effect of internet-delivered interventions on physical activity was d = 0.14 (p = 0.00). Fixed-effect analysis revealed significant heterogeneity across studies (Q = 73.75; p = 0.00). Moderating variables such as larger sample size, screening for baseline physical activity levels and the inclusion of educational components significantly increased intervention effectiveness. Results of the meta-analysis support the delivery of internet-delivered interventions in producing positive changes in physical activity, however effect sizes were small. The ability of internet-delivered interventions to produce meaningful change in long-term physical activity remains unclear. [ABSTRACT FROM AUTHOR]

Background: The aims of this study were to examine temporal trends in the prevalence of sufficient moderate-to-vigorous intensity physical activity (MVPA), high levels of screen time, combined measures of these behaviors and overweight or obesity in Australian adults during the period 2002-2008. Trends over this time period in overweight or obesity within each behavior group (sufficient/insufficient MVPA, high/low screen time and combined behaviors) were also examined. Methods: Data were collected via annually conducted cross-sectional computer-assisted-telephone-interviews (CATI) of adults (n=7908) living in Central Queensland, Australia (2002-2008). Self-reported MVPA, screen time (TV viewing and computer use), and BMI were used to create dichotomous classifications of physical activity (Sufficient MVPA (S-MVPA), Insufficient Physical Activity (I-MVPA)), screen time (High Screen Time (HST), Low Screen Time (LST)), combined behavior categories (S-MVPA/LST, I-MVPA/LST, S-MVPA/HST, I-MVPA/HST) and BMI (Overweight or Obese, Healthy Weight) respectively. Results: The prevalence of S-MVPA, HST, and overweight or obesity increased at approximately the same rate over the study period in the overall sample and females (p?0.05). In the overall sample and in females, the prevalence of overweight and obesity increased over the study period in those individuals classified as I-MVPA/HST (p≤0.05). Conclusion: Results provide evidence that while the prevalence of S-MVPA appears to be modestly increasing, the proportion of the population engaging in HST and classified as overweight or obese are increasing at approximately the same rate. These observations highlight the need to increase levels of total physical activity (including light intensity physical activity) and decrease sedentary behavior including screen time.

Background: Compared to females, males experience higher rates of chronic disease and mortality, yet few health promotion initiatives are specifically aimed at men. Therefore, the aim of the ManUp Study is to examine the effectiveness of an IT-based intervention to increase the physical activity and nutrition behaviour and literacy in middle-aged males (aged 35-54 years). Method/Design: The study design was a two-arm randomised controlled trial, having an IT-based (applying website and mobile phones) and a print-based intervention arm, to deliver intervention materials and to promote self-monitoring of physical activity and nutrition behaviours. Participants (n = 317) were randomised on a 2:1 ratio in favour of the IT-based intervention arm. Both intervention arms completed assessments at baseline, 3, and 9 months. All participants completed self-report assessments of physical activity, sitting time, nutrition behaviours, physical activity and nutrition literacy, perceived health status and socio-demographic characteristics. A randomly selected sub-sample in the IT-based (n = 61) and print-based (n = 30) intervention arms completed objective measures of height, weight, waist circumference, and physical activity as measured by accelerometer (Actigraph GT3X). The average age of participants in the IT-based and print-based intervention arm was 44.2 and 43.8 years respectively. The majority of participants were employed in professional occupations (IT-based 57.6%, Print-based 54.2%) and were overweight or obese (IT-based 90.8%, Print-based 87.3%). At baseline a lower proportion of participants in the IT-based (70.2%) group agreed that 30 minutes of physical activity each day is enough to improve health compared to the print-based (82.3%) group (p = .026). The IT-based group consumed a significantly lower number of serves of red meat in the previous week, compared to the print-based group (p = .017). No other significant between-group differences were observed at baseline. Discussion: The ManUp Study will examine the effectiveness of an IT-based approach to improve physical activity and nutrition behaviour and literacy. Study outcomes will provide much needed information on the efficacy of this approach in middle aged males, which is important due to the large proportions of males at risk, and the potential reach of IT-based interventions.

Although there has been an increase in the availability of effective, evidence-based physical activity interventions in school settings during the past decade, there is a paucity of published research focusing on the translation of these effective interventions into real-world practice. The purpose of this research was to examine the translatability of an existing school-based physical activity intervention. More specifically, this research sought to identify the barriers and facilitators in adopting, implementing, and maintaining a school-based physical activity intervention using RE-AIM as a theoretical evaluation framework. It was concluded that interventions that consider issues around complexity and compatibility with the school setting are more likely to be adopted, implemented, and maintained. It was recommended that future evaluations of physical activity interventions should not be limited to testing internal validity, but should consider external validity and ecological aspects, relevant to increasing dissemination in real-world settings.

Background: Australia continues to witness rising levels of immigration by individuals from Culturally and Linguistically Diverse (CALD) origins. With this rapidly growing diverse population, Australia faces a number of population health challenges. In particular, CALD women have been shown to be at an increased risk of chronic diseases such as cardiovascular disease, diabetes, and poor mental health. Despite the high risk of these diseases, women from CALD groups are less likely to be proactive in accessing health care or undertaking preventative behaviours, such as physical activity participation. The purpose of this study was to examine the socio-cultural influences on the physical activity behaviours of CALD women living in Australia by identifing the barriers, constraints and possible enablers to physical activity participation for this population. Methods: Twelve focus group sessions were undertaken with CALD women (N = 110) from Bosnian, Arabic speaking, Filipino and Sudanese communities in three regions: New South Wales, Victoria, and Queensland. In a semi-structured, open table discussion, participants were encouraged to share their opinions, perceptions and beliefs regarding socio-cultural influences on their physical activity behaviours. Common and ethnic-specific themes emerged from the discussions. Results: Common themes included: knowledge of physical activity, differing physical activity levels, and the effects of psychological and socio-cultural factors, environmental factors, and perceptions of ill-health and injury, on physical activity behaviours. Ethnic-specific themes indicated that post-war trauma, religious beliefs and obligations, socio-economic status, social isolation and the acceptance of traditional cultural activities, greatly influenced the physical activity behaviours of Bosnian, Arabic speaking, Filipino and Sudanese women living in communities throughout Australia. Conclusions: This study demonstrates that attitudes and understandings of health and wellbeing are complex, and have a strong socio-cultural influence. The findings of the present study can be used not only to inform further health promotion initiatives, but also as a platform for further research with consumers of these services and with those who deliver such services.

Background: This study aimed to investigate the validity of the Active Australia Survey across different subgroups and its responsiveness to change, as few previous studies have examined this.Methods: The Active Australia Survey was validated against the ActiGraph as an objective measure of physical activity. Participants (n = 465) wore the ActiGraph for 7 days and subsequently completed the Active Australia Survey. Moderate activity, vigorous activity and total moderate and vigorous physical activity were compared using Spearman rank-order correlations. Changes in physical activity between baseline and 3-month assessments were correlated to examine responsiveness to change. The data were stratified to assess outcomes according to different subgroups (e.g., gender, age, weight, activity levels).Results: With regards to the validity, a significant correlation of ρ = 0.19 was found for moderate physical activity, ρ = 0.33 for vigorous physical activity and ρ = 0.23 for moderate and vigorous physical activity combined. For vigorous physical activity correlations were higher than 0.3 for most subgroups, whereas they were only higher than 0.3 in those with a healthy weight for the other activity outcomes. With regards to responsiveness to change, a correlation of ρ = 0.32 was found for moderate physical activity, ρ = 0.19 for vigorous physical activity and ρ = 0.35 for moderate and vigorous physical activity combined. For moderate and vigorous activity combined correlations were higher than 0.4 for several subgroups, but never for vigorous physical activity.Conclusions: Little evidence for the validity of Active Australia Survey was found, although the responsiveness to change was acceptable for several subgroups. Findings from studies using the Active Australia Survey should be interpreted with caution.Trial Registration: World Health Organisation Universal Trial Number: U111-1119-1755.

Background: Physical inactivity is one of the leading modifiable causes of death and disease in Australia. National surveys indicate less than half of the Australian adult population are sufficiently active to obtain health benefits. The Internet is a potentially important medium for successfully communicating health messages to the general population and enabling individual behaviour change. Internet-based interventions have proven efficacy; however, intervention studies describing website usage objectively have reported a strong decline in usage, and high attrition rate, over the course of the interventions. Web 2.0 applications give users control over web content generated and present innovative possibilities to improve user engagement. There is, however, a need to assess the effectiveness of these applications in the general population. The Walk 2.0 project is a 3-arm randomised controlled trial investigating the effects of "next generation" web-based applications on engagement, retention, and subsequent physical activity behaviour change.Methods/design: 504 individuals will be recruited from two sites in Australia, randomly allocated to one of two web-based interventions (Web 1.0 or Web 2.0) or a control group, and provided with a pedometer to monitor physical activity. The Web 1.0 intervention will provide participants with access to an existing physical activity website with limited interactivity. The Web 2.0 intervention will provide access to a website featuring Web 2.0 content, including social networking, blogs, and virtual walking groups. Control participants will receive a logbook to record their steps. All groups will receive similar educational material on setting goals and increasing physical activity. The primary outcomes are objectively measured physical activity and website engagement and retention. Other outcomes measured include quality of life, psychosocial correlates, and anthropometric measurements. Outcomes will be measured at baseline, 3, 12 and 18 months.Discussion: The findings of this study will provide increased understanding of the benefit of new web-based technologies and applications in engaging and retaining participants on web-based intervention sites, with the aim of improved health behaviour change outcomes.Trial Registration: Australian New Zealand Clinical Trials Registry, ACTRN12611000157976.
