Background:
Rural and regional Australians have a higher likelihood of mental illness throughout their lifetime than people living in major cities, although the underlying reasons are not yet well defined. Additionally, rural populations experience more lifestyle associated co-morbidities including obesity, diabetes and cardiovascular disease. Research conducted by the National Centre for Farmer Health between 2004 and 2009 revealed a positive correlation between obesity and psychological distress among the farming community. Chronic stress is known to overstimulate the regulation of the hypothalamic-pituitary-adrenal (HPA) axis and cortisol secretion which are associated with abdominal adiposity. Increasing physical activity may normalise cortisol secretion and thereby positively impact both physical and mental health. This paper assesses the effects of increasing physical activity on obesity, health behaviors and mental health in Victorian farming men and women.
Methods:
Farming Fit was a six month quasi-experimental (convenience sample) longitudinal design control-intervention study. Overweight or obese (BMI ?25?kg/m2) farm men (n?=?43) and women (n?=?29) were recruited with demographic, health behaviors, anthropometric, blood pressure and biochemistry data collected at baseline and at a six months. Salivary cortisol and depression anxiety stress scale results were collected at baseline, three and six months. The intervention group (n?=?37) received a personalized exercise program and regular phone coaching to promote physical activity.
Results:
The intervention group showed significant reductions in body weight and waist circumference. Results indicated that following the six month exercise program, the intervention group were 2.64???0.65?kg lighter (p?<?0.001), had reduced waist circumference by 2.01???0.86?cm (p?=?0.02) and BMI by 0.97???0.22?kg/m2 (p?<?0.001) relative to the control group.
Conclusion:
Increasing physical activity altered measures of obesity in farm men and women but did not affect mental health measures or cortisol secretion levels.

This editorial captures the essence of each of the papers in this journal and synthesises the findings to highlight the complexity of developing practices that enable students to develop mathematical understandings. Papers described and discussed come from sources internal and external to Australasia. They include new perspectives on analysis of classroom practices, analyses of mathematical registers and mathematical language in classroom activity, action research of a teacher developing new pedagogical understandings, and various analyses associated with teacher education (pre-service teacher programs, interactions between pre-service teachers and their mentors, and how limited content knowledge can affect teacher interpretation of classroom activity. The editorial captures many of the complexities highlighted in the papers and points to the enormity of the expertise required to optimise the teaching of mathematics..

Background The aim of this study was to examine the distribution of physical activity facilities by area-level deprivation in Scotland, adjusting for differences in urbanicity, and exploring differences between and within the four largest Scottish cities. Methods We obtained a list of all recreational physical activity facilities in Scotland. These were mapped and assigned to datazones. Poisson and negative binomial regression models were used to investigate associations between the number of physical activity facilities relative to population size and quintile of area-level deprivation. Results The results showed that prior to adjustment for urbanicity, the density of all facilities lessened with increasing deprivation from quintiles 2 to 5. After adjustment for urbanicity and local authority, the effect of deprivation remained significant but the pattern altered, with datazones in quintile 3 having the highest estimated mean density of facilities. Within-city associations were identified between the number of physical activity facilities and area-level deprivation in Aberdeen and Dundee, but not in Edinburgh or Glasgow. Conclusions In conclusion, area-level deprivation appears to have a significant association with the density of physical activity facilities and although overall no clear pattern was observed, affluent areas had fewer publicly owned facilities than more deprived areas but a greater number of privately owned facilities.

This thesis examined the influences on physical activity, sedentary behaviour and overweight and obesity among a sample of Chinese-Australian and Anglo-Australian adolescents. The results found no significant difference in rates of overweight and obesity; however, lower engagement in daily light-intensity physical activity and greater sedentary participation was revealed among Chinese-Australian adolescents.

Abstract
Objective: To objectively measure physical activity (PA) patterns and sedentary time, and explore perceptions of workplace PA opportunities in regional male transport workers.
Methods: A multi-method study involving 28 drivers (52.4±9.69years) working at a bus company in South-East Queensland, Australia. PA was measured using accelerometers (n=23) to determine the proportion of time spent in sedentary (<150 cpm), light (151–2,689 cpm) and moderate+ (≥2,690 cpm) intensity categories. Paired sample t-tests were used to evaluate differences between categories on a workday/off-workday (n=16), and during work/non-work time (n=15). Interviews were conducted with 28 drivers and six managers to explore perceptions and ideas relating to workplace PA opportunities.
Results: Sedentary time was significantly higher on off-work (64% of wear time) than work (52%) days (p<0.05), while the opposite was the case for light intensity time (off-workday=33%; workday=44%; p<0.05). On workdays, sedentary time was significantly lower when employees were working (44%) than when not working (60%; p<0.05). No significant differences were found for time spent in moderate+ PA. Driver perceptions indicated that PA opportunities (walking club and corporate gym membership) were being adopted by some drivers. However, at this depot, perceived health issues and organisational barriers (shift work and irregular driving routines), tended to preclude some drivers from engaging with these opportunities.
Conclusions: Findings contest the notion that a sedentary occupation such as driving necessitates an inactive work environment.
Implications: This research informs ongoing intervention efforts to target inactive drivers who are struggling to take advantage of existing workplace-related PA opportunities.

ABSTRACT
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.
