measured using the Strengths and Difficulties Questionnaire; level of family functioning was measured using the McMaster Family Assessment Device—General Functioning Scale and parental psychological distress was measured using the Kessler-6 scale. Results: The mean number of servings consumed per day was 2.2(95% CI: 2.1, 2.3) for fruit and 2.0 (95% CI: 1.9, 2.1) for vegetables. The proportion of children meeting the minimum daily age-specific recommendation was 87.8% (95% CI: 86.4, 89.1%) for fruit and 36.5% (95% CI: 34.5, 38.5) for vegetables. Children with behaviour difficulties, low levels of prosocial behaviours and from poorly functioning households consumed fewer servings of F&V than children who did not experience any environment stressors or behavioural problems. Although parental psychological distress was not associated with fruit intake, daughters of parents who reported higher levels of psychological distress consumed fewer servings of vegetables than daughters of parents who reported lower levels of psychological distress. Child behavioural problems and family functioning and to some extent parental psychological distress were associated with F&V consumption. Conclusions: Programmes aimed at promoting F&V consumption in children should target those families with children experiencing behavioural problems or poorly functioning households.
was 62%. Minutes spent in LTPA were trichotomised into categories using published guidelines: sedentary, insufficiently active and sufficiently active. Sex-stratified ordinal regression models were established after standardising scores for HS and SE to minimise collinearity with interaction terms. Results: Among women, HS (p = 0.015) and SE (p < 0.0001) predicted LTPA in the expected direction. The interaction of HS and SE was nonsignificant (p = 0.197). Among men, SE (p < 0.0001) predicted LTPA (in the expected direction), HS was non-significant (p = 0.373) while the interaction term approached significance (p = 0.072). SE questionnaire items were examined individually to identify the key dimensions of SE that predict LTPA. Among women, confidence to engage in LTPA ‘when tired’ was the only significant dimension, while among men, ‘when tired’, ‘in a bad mood’ and ‘don’t have time’ were significant predictors of LTPA. Conclusions: SE was a strong correlate of LTPA in this sample of rural adults, independent of HS. These results highlight the need for physical activity interventions that develop skills and resources to overcome psychological barriers among rural men and women, and time restrictions among men. Conflict of interest: None.

Methods: A questionnaire assessing leisure-time physical activity (LTPA) using the Active Australia Survey, perceived health status (HS), and barriers self-efficacy (SE) was telephone-administered in 2010 to 290 randomly selected 18—65-year olds (170 women) in the South Australian Riverland.

Aim: Food intake is traditionally measured using self-record food diaries which involve logistical and compliance problems. The aim is to develop an improved method of monitoring food intake and energy balance. Method: We have developed a hand-held Electronic Appetite Rating System (EARS) which is used as a research tool for measuring subjective appetite sensations in clinical trials (Gibbons et al., 2011). We are currently working on upgrading the EARS concept by creating a Weight Management application (app) for the Apple iPhone. The app provides continuous feedback about food intake by quantifying and expressing energy intake relative to energy requirements. Patients are provided with an
S58 accumulative total of their energy and macronutrient intake tagged by meal type, and a running tally of calories remaining for their energy requirements. Food and drink items are identified via a barcode using the iPhone’s built-in camera — the portion size (g or ml) is entered manually. The calorie and macronutrient information is automatically retrieved from a nutrition database (AUSNUT 2007). The application utilizes the iPhone’s built-in camera as a barcode reader for EAN, UPC, and other popular barcode formats. A custom 2D barcode reader is also available to produce unique barcodes for items that do not have barcodes. The application is compatible with the Withings body scale designed to monitor body weight using wireless networking (www.withings.com). Conclusion: This app provides a novel platform for improving the measurement of food intake, which could have various implications for the selfmanagement of health behaviours and disease.

POSTER Abstracts Methods: The first stage in developing the HWP was developing its content and structure before design and ‘‘going live’’. This involved the development of a set of inclusion and exclusion criteria to apply to current national and international websites that provided information on healthy living in the workplace. Exclusion criteria included commercial websites and a focus on non-smoking/nutrition/alcohol/physical activity aspects of healthy living such as stress. Websites that met these criteria were dissected for information for inclusion on the HWP (e.g. an online link to an evaluation tool for a healthy living in the workplace program). Australian case studies were also listed on the HWP. Preliminary HWP content and structure were tested via two workshops with stakeholders such as unions, employers and health jurisdictions; one in Sydney and one in Melbourne. Results and conclusions: Results are still being collected and finalised and will be presented at the ANZOS ASM along with conclusions. Conflict of interest: This work is funded by the Department of Health and Ageing. doi:10.1016/j.orcp.2011.08.014 P08 Operationalizing community capacity building— commonalities in two obesity prevention projects A.M.

Aim: The University of Sydney (consortium led by: the Boden Institute of Obesity, Nutrition, Exercise and Eating Disorders; the Workplace Research Centre; and, the Workforce Education and Development Group) was contracted by the Department of Health and Ageing (DoHA) to develop content and related resources for an online National Healthy Workers Portal (HWP). The HWP is a ‘‘one stop shop’’ website to assist employers and employees to implement healthy living programs in Australian workplaces. It provides online links to resources, information and case studies in the areas of smoking, nutrition, alcohol and physical activity.
Aim: Obesity prevention public health projects aim to address the obesity epidemic by affecting population-level behavior. Community-based projects may have the greatest potential, in part due to their capacity building component within communities. Both projects promoted healthy eating and physical activity behaviors with the aim of reducing unhealthy weight gain using a community capacity building approach. Methods: The two projects (Be Active Eat Well, BAEW, and It’s Your Move!, IYM!) were quasiexperimental and longitudinal. Data was generated from in-depth, interview-guided qualitative interviews with project coordinators. BAEW targeted children aged 5—12 years from 2004 to 2008 and had two project coordinators. IYM targeted adolescents aged 13—18 years from 2002 to 2006 and had one project coordinator. Both projects were implemented in Victoria, Australia. Qualitative interview data was assessed by first, a deductive analysis, with categorization of capac-
