Study type
Interventional
Description of intervention(s) / exposure
The intervention is a co-designed culturally appropriate diet and activity digital programme delivered as six modules, one per month over six months via a password protected, sophisticated, web-based application. The modules are: 1) Improve awareness of the health impact of dietary patterns and regular activity 2) Improve awareness of healthy breakfast, meal timings and portion sizes on health 3)Why and how to increase fruit, vegetable and lentil consumption; 4) Why and how to decrease dairy fats and oil consumption 5) Why and how to decrease high fat, high salt and high sugar snacks 6) Why and how to increase activity levels. Each module comprises of a mixture of educational comics, motivational, informational and demonstration video clips and corresponding website information including scientific snippets in an easily digestible format suitable for a lay audience.
Participants will be required to spend a maximum of 60 minutes per module, each month, for six months. Participants can do this in shorter intervals if they prefer over the course of the month. All participation and engagement with each module will be time-stamped and analysed for monitoring adherence.

Statistical methods / analysis
For the pilot study, a total of 100 participants (50 in each group) will be recruited to provide sufficiently precise estimates, including for attrition within each group where 95% CIs for group-specific attrition will be ±14% and overall attrition ±10% (Wald estimates, worst case). Assuming at least 30 participants remain in each group, this will also allow estimating a unit standard deviation with a 95% CI of 0.84–1.25 for baseline measures and 0.80–1.34 for follow-up measures within each group, and 0.88–1.16 and 0.85–1.22 respectively combining both groups. The primary outcomes will be described using appropriate summary statistics (means and SDs, medians and IQRs, and counts and percentages). For the secondary outcomes, an inferential approach will be used with a focus on confidence intervals, and the inclusion of practically important effects, rather than statistical significance. All analyses will be conducted using R 4.0.2 and/or Stata 16.1 (or later versions).

Summary
Brief summary
The aim of the project is to pilot trial a culturally appropriate digitised intervention, designed to improve motivation for positive change in the short term and behaviour change in the long term towards adopting healthier dietary habits and activity levels among SA migrants aged 25 to 59 years. The purpose of the pilot trial is to assess primarily 1) Acceptability of the intervention i.e. whether the content of the intervention modules is relevant, useful, and understandable 2) The level of engagement, uptake of and compliance with the intervention 3) The level of engagement in the control group and secondarily 1) Attrition rates in the Intervention and Control Groups and 2) To investigate the short and medium term potential magnitude and direction of difference, if any, between the intervention and control groups with regard to 1) motivation to adopt health promoting dietary habits and activity levels b) knowledge levels of dietary and activity level impacts on disease prevention and development, and 3) behavioural changes such as a) meeting guidelines for vegetable and fruit consumption b) reduced consumption of high salt foods, deep fried foods and high fat/sugar snacks and c) consistent moderate activity levels.
