Description of intervention(s) / exposure
We are observing over 2 years the relationship between changes in diet (dietary acculturation) and risk factors for cardiovascular disease and type 2 diabetes in Chinese immigrants to Australia. Participants will complete questionnaires, and attend the research facility for anthropometric measurements, blood pressure assessment, AGE reading, and blood samples. All measurements will occur at Baseline, 12 months and 24 months. The expected time commitment annually is 3 hours.

Statistical methods / analysis
Appropriate regression analyses will be used to determine the relationship between exposure variables (age, gender, nutrient intake, dietary acculturation level etc.) and the outcome variable WC. Exploratory regression analyses will be used to look at the relationship with the exposure variable and secondary outcomes. For the primary outcome of change in waist circumference, we will need to include 208 participants (based on effect size of 0.1952304) in order to achieve 80% power.

Summary
Brief summary
Chinese immigrants are at increased risk for obesity and non-communicable disease (e.g diabetes, cardiovascular disease) after migration due to an interacting set of factors, including dietary change, cultural barriers, and genetic predisposition. To better understand the increased risk among immigrants, it is important to consider the dietary shift that occurs when Chinese immigrants move to Australia. The goal of our research study is to understand how and why Chinese immigrants change their dietary habits after migration and what impact these dietary changes have on risk factors for diabetes and cardiovascular disease. We hypothesise that over the two-year observation period there will be 1) evidence of dietary acculturation in Chinese immigrants to Australia; and 2) changes in risk factors for cardiovascular disease and diabetes.
