S24 Poster Abstracts adapted from a similar WHO tool and a set of best practice principles for community-based obe- sity prevention, aimed to determine the depth and breadth of projects. Full results from the survey will be pre- sented. Preliminary results show wide variation in Australian community-based obesity preven- tion projects. These initiatives differ between the states of Australia in terms of number, location, funding, target group, strategies and evaluation. Consistency in community-based obesity pre- vention projects in Australia is of national and international importance in addressing the current obesity epidemic. There is potential for the tool developed in this study to be applied to other coun- tries such that obesity prevention efforts can be compared and improved. doi:10.1016/j.orcp.2010.09.046 P48 The association between participation in a 4-month pedometer-based workplace physical activity program and health-related quality of life (HRQOL) J.

Recommended levels of physical activity (PA) are associated with a decreased risk for many chronic health conditions such as cardiovascular disease, obesity and Type II diabetes. The use of pedometer-based workplace programs is increas- ing to improve employee’s health. While there is some evidence that such programs increase physi- cal activity levels, their impact on health-related quality of life (HRQOL) is unknown. The aim of the following study is to assess whether participation in a workplace PA program will lead to subsequent improvements in HRQOL. For this study we use a cohort of voluntary, educated adults employed in relatively sedentary occupations. These employees were already enrolled in the GCC ® evaluation study, examining the health benefits of participation in the Global Corporate Challenge (GCC ® ). Methods and results: 774 employees from 10 workplaces across Melbourne participating in a 4-month workplace PA intervention (the GCC ® ) vol- unteered to participate in this evaluation study. Study participants had biomedical measurements taken in the workplace and completed web- based surveys including demographic information, behavioural measures, physical activity, heath sta- tus and quality of life. The validated SF-12 health survey was utilised to assess HRQOL. Data collection was performed at baseline (prior to commencement of the GCC program) and at four months (at the end of the GCC program). This paper presents a before and after analysis of HRQOL. Independent t-tests shall be utilized to compare differences in HRQOL measurements at baseline and 4 months. Analy- ses shall assess differences between baseline and 4 months for overall HRQOL, the physical compo- nents scores (PCS), the mental components scores (MCS) and potential further break-down scores of the SF-12. Further analysis stratifying by age and sex shall be undertaken. Future implications: It is unknown whether par- ticipation in a program such as the GCC ® will lead to an increase in HRQOL in both the short and longer- term. This study will lead to a further understanding of the effects of participation in workplace physical activity programs so that future public health ini- tiatives can be directed at successful interventions to increase physical activity and associated HRQOL.

Combined with other interventions, reducing children’s exposure to this type of adver- tising has been identified as a target for preventive action. Currently in Australia, food marketing to chil- dren is regulated through a mixed approach of both statutory regulation and industry self-regulation. This mixed regulatory system fails to provide a coordinated and comprehensive arrangement, but rather results in a complex and confusing system, which relies on public complaints to monitor com- pliance. Cancer Council NSW established the Food Mar- keting Complaints Registry in June 2010 to provide
