Mobile technologies and physical activity behaviour: an example of what you can do with your accelerometry and GPS data

Session - S25 Always in touch: physical activity promotion via social media and modern technology: abstract S25.3Conference Theme: Promoting Healthy Eating and Activity WorldwidePURPOSE: The ability of mobile technologies to continuously collect a large amount of objective data on physical activity (PA) and their correlates can assist the identification of potential determinants of PA behaviour. However, modeling such data, with multiple sources of dependency, can be challenging. METHOD: Objective data on PA and locations were collected on a sample of 95preschoolers using accelerometers and Global Positioning System (GPS) mon…postprin

Predictors of pre- and post-competition affective states in male martial artists: a multilevel interactional approach

The aims of this study were to examine (a) the effects of competition-related and competition-extraneous concerns on affective states; (b) the relationships of primary and secondary appraisal with affective states and (c) the main and moderating effects of personality traits on pre- and post-competition affects. Thirty-nine male elite martial artists were assessed on 12 affective states, concerns and dimensions of primary and secondary appraisal at five random times a day across 1 week before and 3 days after a competition. On the competition day, they were assessed 1 h before and immediately after the contest. Competitive trait anxiety, neuroticism and extraversion were measured at the start of the study. The competition was the most significant and stressful event experienced in the examined period and had a pervasive influence on athletes' affective states. All examined appraisal and personality factors were somewhat associated with pre- and post-competition affective states. Competitive trait anxiety was a key moderator of the relationship between cognitive appraisal and affective states. This study supports the idea that cognitive appraisal and situational and personality factors exert main and interactive effects on athletes' pre- and post-competition affects. These factors need to be accounted for in planning of emotion regulation interventions

How socio-economic status affects physical activity participation in Hong Kong adolescents.

Conference Theme: Promoting Healthy Eating and Activity WorldwideSession - S30 The IPEN Adolescent Study: results on the associations of neighborhood income and walkability on physical activity and sedentary behaviors: abstract 30.2PURPOSE: There is evidence that socio-economic status (SES) is associated with physical activity (PA) participation. Lower SES is predictive of lower levels of leisure-time PA. However, most of this research has been conducted in the West and on adults. SES inequalities in PA among youth and Asian populations remain are underexplored. Thus, this study examined SES differences in PA among Hong Kong adolescents and explored environmental and psychosocial mediators of the relationships between SES indicators and PA participation. METHOD: A sample …postprin

Objective evaluation of recreational facilities: Development and reliability of the Recreational Facility Audit Tool

The characteristics of recreational facilities are determinants of facility use and physical activity, yet there are few validated and extensive audit tools gauging characteristics of recreational facilities. This study aimed to describe the development of a 111-item audit tool that objectively evaluates the characteristics of recreational facilities across 10 domains, including the availability of sports facilities, accessibility to the facility, availability of supportive amenities, conditions of changing rooms, conditions of toilets, management, policy, environmental safety, aesthetics, and social environment. The intra- and inter-rater reliability indices of the audit tool were also examined. In the intra-rater reliability tests, 20 recreational facilities were examined twice by the same auditor, with one week apart between each audit. The inter-rater reliability was assessed using data from 20 recreational facilities that were examined twice by two independent auditors. Kappa statistics, percent agreement and intra-class correlation coefficients were computed. The average intra- and inter-rater percent agreement was 96.9% and 90.6% respectively. The majority of items (n=107 and 101) showed either good percent agreement or acceptable kappa values in the intra- and interreliability tests respectively. The overall intra- and inter-rater reliability of the audit tool was acceptable. Subjective and time-sensitive audit items may need clearer descriptions and multiple repeated measures to improve their reliability. The audit tool can be used to reliably assess indoor sports centres, parks, sports grounds, playgrounds and swimming pools. The objective data collected by this audit tool would contribute to the understanding of relationships between characteristics of recreational facilities, usage and physical activity.published_or_final_versio

Exploring mechanisms of behaviour change in interventions using mobile technologies: new opportunities

abstract no. O29.3Theme: Promoting healthy eating and physical activity: The latest international researchPURPOSE: The identification of mechanism of behaviour change is necessary for the systematic progression of physical activity (PA) and dietary behaviour research. The ability of mobile technologies to continuously collect a large amount of objective data on behaviours (e.g., PA levels and geographical locations) and self-report data on related psychosocial mechanisms (e.g., barriers to PA) in “real-time” has the potential to substantially advance our understanding of whether and how intervention strategies can change people’s behaviour. METHODS: Using simulated data on a hypothetical mobile phone- and GPS-based PA intervention programme, three types of statistical models …postprin

Assessment of Measures of Physical Activity of Children with Cerebral Palsy at Home and School: A Pilot Study

Home and school are important settings where children can accrue health promoting physical activity (PA). Little is known about the PA levels and associated environmental characteristics at home and school in children with cerebral palsy (CP). An observational tool - Behaviors of Eating and Activity for Children’s Health Evaluation System (BEACHES) - offers potential for providing information. Objective: To validate BEACHES against Actigraph accelerometer and to document PA of children with CP at a special residential school facility for children with physical disabilities. Methods: Five children with CP (2 girls, 3 boys; aged 9.82 ± 2.39 years) in Level I of the Gross Motor Function Classification System (GMFCS) participated. PA monitoring was conducted once a week during four consecutive weeks at morning recess at school and during after school hours at the children’s residence. Estimates of time spent being sedentary and being active were derived from the Actigraph and compared to estimates obtained with BEACHES. Results: Children’s PA observed using BEACHES was comparable to the Actigraph estimations. In general, children were more active at recess than after school and the physical locations assessed by BEACHES were associated with objectively measured PA time. Conclusion: This pilot study indicates that BEACHES appears to be a suitable measure of PA for children with CP in both home and school settings. Additional study with a larger and more diverse sample is recommended to verify the results

Physical activity for children in special school environment

&nbsp;Key Messages1. We assessed children&rsquo;s physical&nbsp;activity (PA) in structured (physical&nbsp;education) and unstructured&nbsp;(recess, lunch, before and after&nbsp;school) periods in special schools&nbsp;and examined its association&nbsp;with modifiable area contextual&nbsp;characteristics.2. Children with disabilities were not&nbsp;highly active, but were more active&nbsp;during recess and lunch periods&nbsp;than at other times including&nbsp;physical education classes.3. Areas were often not accessible&nbsp;during unstructured settings.&nbsp;Children were more active in areas&nbsp;when supervision and organised&nbsp;activities were provided.4. Providing an interactive game&nbsp;during free play did not significantly&nbsp;increase group&rsquo;s PA.5. Children&rsquo;s PA accrual is influenced&nbsp;by contextual characteristics of&nbsp;the school environment. There is a&nbsp;need to make areas more accessible&nbsp;and to use social marketing and&nbsp;programming to attract more users.&nbsp;School and health professionalsshould modify contextual&nbsp;characteristics by providing more&nbsp;direct supervision and organised&nbsp;activities during free play.</div

Recreational destinations and leisure-time physical activity in Chinese urban elders

Conference Theme: Promoting Healthy Eating and Activity WorldwideSession - S36 The relationships between the physical environment and physical activity in older adults: results from four different continents: abstract S36.4PURPOSE: The built environment may impact on elders’ ability to engage in leisure-time physical activity (LTPA). Environmental correlates of LTPA in Chinese older residents of ultra-dense cities are unknown. The main aim of this study was to examine associations of objectively-measured recreational facilities in the neighborhood with LTPA (walking and other forms of activity) in Chinese elders residing in an ultra-dense city. We also examined whether these associations depend on other environmental factors. METHOD: This study was conducted in Hong Kong in …postprin
