Obesity quality of life measure

Developing a preference based quality of life measure for use in economic evaluation of weight management programmes for overweight and obese adolescents

Background

Obesity, particularly in the younger population, is a major public health concern as the proportion of young people classified as overweight or obese has been rising over the years.

Due to the long-term health risks of childhood obesity (such as respiratory diseases and type 2 diabetes) and the emotional and psychological effects of being obese, public health initiatives and specialised weight management interventions have been developed specifically for the adolescent population.

Economic evaluations are used to inform resource allocation decision making in the healthcare context. A valid and reliable tool to: (a) measure weight related quality of life (QoL) and (b) assign preference values to different aspects of weight related QoL is necessary to carry out fully informed cost utility analysis (CUA) of weight management interventions aimed at adolescents.

A video introduction has been produced.

Aim & Objectives

  • To create a new weight-related questionnaire appropriate for adolescents aged 11–18 years and for the elicitation of preference values
  • To elicit preference values to make the questionnaire suitable for carrying out cost utility analysis (CUA)

Methods

The first phase of the study involves the development of a new weight specific questionnaire. Questions (items) and response categories (levels) will be generated from interviews with adolescents assessing the impact of weight status on different aspects of their lives.

In the second phase, statistical analysis will be used to assess the performance of the newly-developed questionnaire. A web survey will be created for adolescents to complete. The data generated from this will be used to perform the statistical analysis.

The final phase involves the preference elicitation study, where health states generated from the final version of the questionnaire will be valued to allow calculation of quality adjusted life years (QALYs).

Results

Information on the results of this research will appear here as the work progresses; however, if you would like further information, please contact Yemi Oluboyede.

Impact

Utilisation of the new weight-related instrument should lead to better informed commissioning decisions within the National Health Service (NHS), local government and local authorities in the United Kingdom. It will facilitate a more complete assessment of the impact of adolescent obesity in future economic evaluations by integrating adolescents’ views into the research process. Overall the research will provide a further impetus to addressing obesity within the NHS and wider government policy.
