Appendix 2 Literature Review – Childhood Obesity Obesity – Background All of the literature refers to similar statistics regarding obesity. The list below gives some examples of the data available from the different sources. ¦ ¦ ¦ ¦ Obesity has more than doubled between 1990 and 2000 in Britain.

One in 10 six year olds (8. 5%) are obese. One in six (15%) 15 year olds is obese. If the current trends continue, one fifth of boys and one third of girls will be obese by 2020. Obesity is measured using the Body Mass Index (BMI) for an individual.

This is measured through a calculation relating height to weight and age, and there are agreed figures for obesity. This problem is not just limited to the UK. Obesity is rising in other developed countries, most notably the USA.

No-one has managed to reverse this trend. 1 Implications of Obesity 1) Premature mortality a) Linked to 30,000 deaths a year b) Shortening of life by an average of 9 years2 2) Cost to NHS a) ? 0. 5 billion pa3 3) Cost to economy4 a) ? 2 billion b) 18 million sick days pa 4) Increased risk of disease. 6 Most are diseases of adult life, but overweight adolescents have a 70% chance of becoming overweight or obese adults. 7 a) Heart disease – the most common cause of premature death among obese people (estimated 28000 heart attacks caused by obesity in 1998) b) Type 2 diabetes – this was previously considered to be an adult disease but has appeared in obese school children c) High blood pressure d) Osteoarthritis and back pain e) Hypertension f) Asthma g) Cancer, especially colon 1 2 Wanless, D.Select Committee on Public Accounts 3 NAO 4 NAO 5 NAO 6 Ebbeling et al.

The available data reveals: a) Television viewing – lack of physical activity combined with propensity to eat.

Possibility that television advertising could affect eating habits (eg. andom sample of children’s tv showed 34% of adverts were for junk food) b) Also includes video games, computers and the internet c) Reduction of physical activity in schools: i) A survey by Sport England showed that the proportion of young people spending two or more hours a week on sport in school declined from 46% in 1994 to 33% in 1999) ii) The National Diet and Nutrition survey (2000) found that 40% of boys and 60% of girls failed to meet a Health Education Authority recommendation that children should engage in at least moderate physical activity for one hour per day. 7 d) Urban environments discouraging physical activity e) Decline in children walking and cycling to school 8 9 Ebbeling et al.

Obesity in children is also higher among manual groups and ethnic inequalities in the prevalence of overweight are also apparent, with higher rates among Asian groups. Strategies to Deal with Obesity Strategies ultimately need to deal with eating less and becoming more physically active. 31 18 19 20 NAO POST Ebbeling et al. 21 Wanless, D. 22 All-Party Parliamentary Group on Obesity 23 Ebbeling et al.

Currently, there is no national intergovernmental plan for healthy eating and exercise although most PCTs are drawing up obesity strategies. 32 Action needs to be taken at all levels, including national, local, community and individually and concentration should be on solutions, not problems. 33 However, it is noted that as obesity is a long-term problem, it is not necessarily attractive for governments. 34 There is a lack of good quality evidence which supports the effectiveness of interventions to prevent obesity. 5 However, the Health Development Agency has looked at this issue and a summary of evidence of success of interventions is presented at Appendix A. 1) Prevention36 2) Further research37 a) Research on prevention and effective interventions b) Research on policy options c) Research to improve understanding of societal and cultural factors behind this trend eg.

child poverty 3) Department of Health38 a) Appraisal of the effectiveness of treatments b) Build on NSF for coronary heart disease c) Disseminate guidelines for the management of obesity d) Research through a ross-departmental group e) Development of a cross-Government strategy to promote health benefits of physical activity 4) Public Services a) Initiatives should be implemented at local level – public services should take the lead by promoting healthy eating and increased physical activity in public places eg. schools, hospitals. 39 See below for further discussion. b) Need for extra resources to tackle “complex” problem40 5) Local Health Improvement Programmes within the NHS a) Few local strategies nationally to address obesity specifically – patchy.Appropriate strategies need to be developed focusing on those most at risk. 41 i) Action is currently being taken through the prevention themes of national CHD and cancer programmes ii) It is also part of the NSFs such as for CHD and diabetes42 b) Should be included in all plans and policies.

The money comes from various sources including the National Lottery New Opportunities Fund and the National School Fruit Scheme. They would like to see ringfenced funding but at the moment they are moving resources from somewhere else. Newark and Sherwood PCT ¦ ¦ ¦ ¦ Leads on obesity for the four Nottinghamshire PCTs; Employs community nutrition assistant and active lifestyle officer (funded by NHS but working through district councils); patients referred through GPs, health visitors and social services; Community nutrition assistant teaches home economics to low income groups including supermarket tours and education on healthy eating; Active lifestyle officer runs exercise referral programmes.Newcastle PCT83 “Newcastle PCT established a Specialist Weight Management Service (SWiMS) following a survey undertaken by Newcastle University that identified high prevalence of obesity among Newcastle residents (41 per cent of men and 54 per cent of women). Funded by Neighbourhood Renewal, the service is staffed by a programme manager, fitness instructor, psychologist, dietician and community nutrition assistant together with administrative support.

“The service links with primary, secondary and tertiary care (including diabetes and cardiac rehabilitation services), with physiotherapy and with council funded and private leisure facilities. Referral to SWiMS can be from any of these routes or clients can self-refer. The service offers 3 levels of provision depending on BMI: • • • • Level 1 services are those that were already in existence prior to the development of SWiMS and include primary care advice and management of overweight and obesity, and leisure services. Level 2 services provide weekly groups sessions over a 12 week period offering dietary advice, physical activity and psychological support to those with a BMI >25.

Level 3 services are provided for the house bound or those with morbid obesity (BMI >40). 83 Wanless, D. , pp. 61. “Individual or small group interventions are provided with a programme tailored to the individual. This involves a range of activity including physiotherapy, dietary advice and psychological support.

For those with morbid obesity the service has links with tertiary care services and can refer directly for assessment of the need for gastric surgery. “Follow-up at 6 and 12 months is provided for all clients. “Evaluation of clients at one year follow-up demonstrated sustained physical activity and weight loss together with a reported increase in self-esteem and confidence. “An independent evaluation of the service has been commissioned from Northumbria University. ” Other Programmes Carnegie International Weight Loss Programme84 Six week programme involving: Dietary modification Physical activity Education Tries to give fun and positive environment for weight loss Does not ‘ban’ e. g. oing to McDonalds but shows children how to behave in that situation Tries to teach children relevant experiences to allow them to make good food choices Supplemented by follow up weight management clinic and home visits – ongoing treatments Works with whole family Difficult to assess success (due to lack of research) but appears that: There is a definite reduction in BMI and percentage of body fat An increase in fitness levels Improved self esteem and self image 84 All-Party Parliamentary Group on Obesity Appendix A Taken from: Health Development Agency (HDA).
