ABSTRACT
Background:
Excess weight is a major risk factor for chronic diseases. In Australia over 60% of adults are now overweight or obese. The overconsumption of energy-dense nutrient poor (EDNP) foods and low physical activity (PA) levels are key factors contributing to population obesity. New cost-effective approaches to improve population diet and PA behaviors are needed.
Objective:
This 1-year randomized controlled trial (6-month intervention; 6-month follow-up) aims to investigate whether a tailored intervention using mobile technology can improve diet and PA behaviors leading to weight loss in adults (18-65 years) who are overweight or obesity, recruited through a social marketing campaign (LiveLighter®).
Methods:
All eligible participants will complete demographics and lifestyle behaviors online at baseline, 6- and 12-months. Using a two stage randomization they will be allocated into one of three groups: 1) tailored feedback (TF) delivered via email at seven time points informed by objective dietary (mobile food record application™) and activity (wearable activity monitor) assessment; 2) active control (AC) receiving no tailored feedback, but undergoing the same objective assessments as TF; and 3) online control (OC) receiving no tailored feedback or objective assessments. Primary outcome measures at 6- and 12-months are changes in body mass, EDNP foods and beverage consumption and daily moderate-to-vigorous PA (measured via accelerometery). Secondary outcomes include change in fruit and vegetable consumption, daily sedentary behaviors and cost-effectiveness.
Results:
Enrolment commenced in August 2017. Primary outcomes at 12-months will be available for analysis from September 2019.
Conclusions:
Tailored email feedback provided to individuals may provide a cost effective strategy to overcome existing barriers to improving diet and PA. If shown to be successful and cost-effective, upscaling this intervention for inclusion in larger-scale interventions is highly feasible. Clinical Trial: Australian New Zealand Clinical Trials Registry ACTRN12617000554369.
