Cross-sectional study protocol for the Arabic Healthy Weight Project promoting active living and healthy eating among Arabic-speaking communities in South Western Sydney

INTRODUCTION: The South Western Sydney Local Health District (SWSLHD) is home to nearly 75 000 Arabic-speaking people. Of these, nearly three quarters are overweight or obese and suffer from a range of chronic diseases. To address this, the Health Promotion Service of SWSLHD will conduct a community-based overweight and obesity prevention intervention (Arabic Healthy Weight Project, 2018–2021) with Arabic community members aged between 18 and 50 years. The intervention’s main activities will include a comprehensive social marketing campaign and an ‘Eat-Move-Live Healthy’ programme. METHODS AND ANALYSIS: The project will be evaluated using a pre–postintervention study design to measure changes in practices in relation to physical activity, consumption of vegetables and intake of sugar-sweetened beverages. The evaluation will apply mixed data collection methods. The quantitative data will be collected using a face-to-face survey of 1540 participants from two independent samples (pre: 770 and post: 770). Descriptive and inferential statistical tests will be used to analyse the quantitative data. The qualitative component will use focus group discussions and interviews to evaluate the formative, process and follow-up phases of data collection. A combination of deductive and inductive methods of data analysis will be conducted using NVivo software. ETHICS AND DISSEMINATION: The protocol has been approved by the Human Research Ethics Committee of SWSLHD (HREC/16/LPOOL/303). Findings will be published in peer-reviewed journals.
