TRIAL DESCRIPTION
Public title The development, implementation and evaluation of a weight loss intervention for overweight/obese primary school educators at selected schools within the Metro North District in Western Cape Province, South Africa: A randomized controlled trial.
Official scientific title The development, implementation and evaluation of a weight loss intervention for overweight/obese primary school educators at selected schools within the Metro North District in Western Cape Province, South Africa: A randomized controlled trial.
Brief summary describing the background and objectives of the trial The aim of this study was to develop, implement and evaluate a weight loss intervention for overweight/obese primary school educators at selected schools within the Metro North district in the Western Cape Province, South Africa in a randomized control trial. Phase 1: Development of the intervention Specific objectives To develop a novel weight loss intervention aimed at improving food choices and thereby reducing total energy intake and increasing physical activity levels of overweight/obese educators by: • Selecting an intervention development framework • Application of the framework for development of intervention strategies/actions/messages • Integration of behaviour theory in the intervention planning process Phase 2: Randomized controlled trial to evaluate a weight loss intervention for overweight/obese primary school educators at selected schools within the Metro North district in the Western Cape Province, South Africa. Specific objectives: • To perform baseline assessments of the descriptive, primary, secondary and process outcomes of the study • To implement the intervention and conduct follow-up assessment at 16 weeks (at completion of the intervention) of the primary, secondary and process outcomes of the study • To conduct analyses to investigate within group change over time in primary, secondary and process outcomes. • To conduct analyses to investigate whether there is a difference between the control and the intervention groups in change over time in primary, secondary and process variables. • To conduct analyses to investigate the contribution of change in beliefs to change in the primary outcome variables. Phase 3: Feasibility of a weight loss intervention for overweight/obese primary school educators at selected schools within the Metro North district in the Western Cape Province, South Africa. Specific objectives: • To investigate the perception of educators who participated in the intervention arm using semi-structured in-depth interviews
