Process evaluation of a community-based adolescent obesity prevention project in Tonga


The rising burden of obesity in Tonga is alarming. The promotion of healthy behaviours and environments requires immediate urgent action and a multi-sectoral approach.

A 3 year community based study titled the Ma'alahi Youth Project (MYP) conducted in Tonga from 2005-2008 aimed to increase the capacity of the whole community (schools, churches, parents and adolescents) to promote healthy eating and regular physical activity and to reduce the prevalence of overweight and obesity amongst youth and their families. This paper describes the process evaluation for MYP, against a set of Best Practice Principles for community-based obesity prevention.

Methods: MYP was managed by the Fiji School of Medicine.

A team of 5 staff in Tonga were committed to planning, implementation and evaluation of a strategic plan, the key planks of which were developed during a two day community workshop. Intervention activities were delivered in villages, churches and schools, on the main island of Tongatapu.

Process evaluation data covering the resource utilisation associated with all intervention activities were collected, and analysed by dose, frequency and reach for specific strategies.

Results: The action plan included 4 nutrition and 2 physical activity objectives; one (1) around championing key people as role models; plus three (3) standard objectives around capacity building, social marketing and evaluation. Whilst the interventions included a wide mix of activities straddling across all of these objectives and in both school and village settings, there was a major focus on social marketing and physical activity initiatives, The intervention reach, frequency and dose varied widely across all activities, and showed no consistent patterns.

Conclusions: The adolescent obesity interventions implemented as part of the MYP program comprised a wide range of activities conducted in multiple settings, touched a broad spectrum of the population (wider than the target group), but the dose and frequency of activities were generally insufficient and not sustained.

Also the project confirmed that, whilst the MYP resulted in increased community awareness of healthy behaviours, Tonga is still in its infancy in terms of conducting public health research and lacks research infrastructure and capacity.
