Objectives - To develop and pilot a community-based family programme,‘Families for Health’, for intervention with overweight and obese children aged 7-11 years.
Intervention – ‘Families for Health’ is a 12-week programme, with parallel groups for parents and children, combining support for parenting, lifestyle change, as well as social & emotional development.
Design of the Evaluation – Pilot study using mixed-methods comprising: process evaluation; outcome evaluation involving a ‘before and after’ evaluation and triangulation with interview data; economic evaluation (cost-outcome description); users and providers perspectives.
Setting – Leisure Centre, Coventry, England Participants – 27 overweight or obese children aged 7-13 years (18 girls, 9 boys) and their parents, from 21 families.
Process Evaluation – Two groups were run, and were delivered as planned. Recruitment was difficult, although most effective via the media. Attendance rate was 62%, with 18(67%) children completing the programme.
Outcome Evaluation – Primary outcome was change in the BMI z-score from baseline. For 22 children with follow-up data, BMI z-score was significantly reduced by -0.18 (95% CI -0.30 to -0.05, p=0.008) at the end of the programme, and was sustained to 9-months (-0.21) and 2-years (-0.23). There were also significant improvements in the children’s quality-of-life, eating and activity environment, child-parent relationships and parent’s mental health. Fruit and vegetable consumption, participation in moderate/vigorous exercise, and children’s self-esteem did not change significantly. Interview data illustrated the changes made by the families, particularly to their eating environment.
User and Provider Perspectives – The group-based parenting approach was received well, providing the ‘tools’ for parents to become ‘agents of change’ in the family. Suggested changes to the programme include providing follow-up sessions and a greater focus on physical activity.
Economic Evaluation - Costs to run ‘Families for Health’ were £517 per family or £402 per child, in-line with other group-based obesity management or parenting interventions.
Conclusion - ‘Families for Health’ is a promising new intervention for the management of childhood obesity.
Editor's comments - [ The above is the abstract from an original PhD thesis; the final publication in the study for the author in pursuit of a doctorate; such works result in the author being awarded a PhD and the title of Dr. by an appropriately accedited University. PhD's are the culmination of a number of years work by the author supervised by two (normally PhD or MPhil qualified) academics and, with the addition of a further appropriately qualified academic (not normally from the same University) as part of a viva-voce examination team. Successful research work at PhD level is designed to add to the body of knowledge in the study area at some level.
A PhD thesis often forms the foundation for journal articles for the author and leads to further enquiry in the form of what is called post-doctoral research. These works are characterised by comprehensive literature reviews, sometimes traditional yet multiple (and often mixed) methods, interesting if not ground breaking discussions and always directional signs toward further research; they provide for undergraduates not only a model for the possibilities for further study but a gift in terms of references in any given subject areas.
To reference an eThesis the convention in the text is the same as a book; author (date), in the reference list there is some debate; theses are more often than not, unpublished works, yet when listed on databases at Universities or elsewhere it could be argued that they are published.
Our best advice is to reference list internet sourced theses as ‘published’…. ie.; Author, (date). Title (emphasised). Place of publication and (university) publisher. Available from: URL reference. See our example reference below. ]
