Measuring diet and physical activity in weight management interventions
This paper is intended to be an accessible and practical guide to the measurement of physical activity and diet and provides a shortlist of practical, validated tools to:
support people conducting evaluations of weight management interventions
help provide consistency and comparability between evaluations of weight management interventions and to strengthen the evidence base
support the implementation of the Standard Evaluation Framework (SEF) for weight management interventions.

Obesity and Mental Health
This paper provides an overview of current evidence on the relationship between obesity and mental health in the UK and highlights the co-directional associations between common mental health disorders and obesity. It also includes:
- issues around inequality
- the implications of psychological distress caused by weight related stigma and discrimination
- specific issues relating to child and adolescent obesity
- current knowledge on the effectiveness of interventions

Obesity and ethnicity
This paper provides an overview of the current evidence on the relationship between obesity and ethnicity for adults and children in the UK - summarising evidence on:
- variations in obesity prevalence between and within minority ethnic groups;
- differences in obesity-related disease prevalence between minority ethnic groups, with particular reference to cardiovascular disease and type 2 diabetes;
- measures of obesity including the issue of central adiposity and the use of BMI; and
- the role of potential determinants of obesity for minority ethnic groups such as migration, cultural variations in diet, socioeconomic status, local area characteristics and physical activity levels.

Data Sources: knowledge of and attitudes towards healthy eating and physical activity
This paper identifies and describes the main sources of national-level data on knowledge of, and attitude towards healthy eating and physical activity in adults and children in England. Descriptions are provided for the available sources of data, the methods used for their collection and their limitations. The focus is on data that are systematically and regularly collected from the national population and are in the public domain.

Physical activity in the Active People Survey: developing an indicator that includes walking and cycling for transport
This paper describes analysis of the Sport England Active People Survey to calculate the percentage of adults that participate in moderate intensity physical activity that includes walking and cycling for transport, for 30 minutes or more on at least three days per week and at least five days per week.
The data are presented separately in the form of an interactive mapping and analysis tool (e-atlas), on the NOO website. The data are presented in both the adult single map e-atlas and the adult dual map e-atlas.

Healthy Weight, Healthy Lives: Market Segmentation and Mapping
The 'Healthy Weight Healthy Lives: Consumer Insight Summary', published in November 2008, describes market research into families' attitudes and behaviours relating to diet and physical activity and looks at how families can be grouped into six clusters. This work was commissioned in order to inform the development of the national Change4Life campaign.
Follow-on work was subsequently undertaken to produce a more detailed geographical mapping of the identified clusters. This briefing note aims to summarise the geodemographic segmentation approach and give guidance on the appropriate use of the cluster postcode directories and maps.

Measures of central adiposity as an indicator of obesity
High levels of central adiposity in adults are known to be associated with increased risk of obesity-related conditions including type 2 diabetes, hypertension and heart disease. Although measures of central adiposity are closely correlated with BMI, they have been shown to predict future ill health independently of BMI.

International comparisons of obesity prevalence
The purpose of this paper is to provide a single resource for international comparisons of obesity prevalence focused on the United Kingdom (UK) and to inform the debate on trends in adult and childhood obesity levels within the UK by providing a global comparison.

Body Mass Index as a measure of obesity
This Q and A style briefing paper provides an overview of the use of body mass index (BMI) for the measurement of obesity.
BMI is a person’s weight in kilograms divided by the square of their height in metres. It is one of the most commonly used ways of estimating whether a person is overweight and hence more likely to experience health problems than someone with a healthy weight. It is used to measure population prevalence of overweight and obesity. It is also a relatively easy, cheap and non-invasive method for establishing weight status. However, BMI is only a proxy for body fatness. Factors such as fitness, ethnic origin and puberty can alter the relation between BMI and body fatness and must be taken into consideration. Other measurements such as waist circumference and skin thickness can be collected to indicate a person’s weight status or body fatness. None of these is as widely used as BMI.

Physical activity surveillance in England: what is measured and where are the gaps?
This paper aims to identify and describe the main sources of national level surveillance data on physical activity in adults and children in England, in order to identify any important gaps. This is distinct from the measurement of physical activity at a local level in order to evaluate the impact of specific interventions or for local needs assessments. The paper focuses on data on the population prevalence of physical activity, but also includes key sources of available data on determinants of physical activity (such as characteristics of the built environment).
