TACKLING OBESITY IN ENGLAND12 With<strong>in</strong> general practice, there is a wide range of different methods whichgeneral practitioners and practice nurses use for manag<strong>in</strong>g overweight andobese patients, and many rema<strong>in</strong> uncerta<strong>in</strong> about which <strong>in</strong>terventions are themost effective. Whilst drug therapy, for example, was used by about 40 per centof general practitioners <strong>in</strong> our survey, most of those we <strong>in</strong>terviewed hadreservations about its effectiveness, despite recognis<strong>in</strong>g that it could be a usefulaid to accelerat<strong>in</strong>g weight loss for some patients. The <strong>National</strong> Institute forCl<strong>in</strong>ical Excellence is currently undertak<strong>in</strong>g an exam<strong>in</strong>ation of anti-obesitydrugs to enable it to advise on their cl<strong>in</strong>ical and cost effectiveness.13 We also found some confusion over roles and responsibilities, and evidence ofa lack of 'buy <strong>in</strong>' by general practitioners for help<strong>in</strong>g overweight and obesepatients to control their weight. There are wide divergences between practicesover aspects of management, <strong>in</strong>clud<strong>in</strong>g their use of health promotion on weightcontrol, diet and physical activity, and the extent to which they try to assesswhich patients are at risk from excessive weight ga<strong>in</strong>. Only a small m<strong>in</strong>ority ofpractices were us<strong>in</strong>g a protocol for the management of obese patients, but themajority said that they would f<strong>in</strong>d a national protocol or guidel<strong>in</strong>es useful.14 In general, there is little NHS activity related to the management of obesityoutside general practice. Some hospitals provide a valuable service byscreen<strong>in</strong>g pre-operative patients for obesity, and referr<strong>in</strong>g those who mightbenefit from weight management to their general practitioner for advice andtreatment. There are also a number of specialist centres for the treatment ofobesity, normally offer<strong>in</strong>g drug therapy, and about 200 surgical <strong>in</strong>terventionsfor cases of extreme obesity each year. Resource constra<strong>in</strong>ts prevent specialistcentres from treat<strong>in</strong>g more than a small m<strong>in</strong>ority of those obese patients whoseek help from the NHS. There may be scope for more patients to benefit fromsuch specialist treatments, although to date there is only limited evidence oftheir long term effectiveness.15 We conclude that the NHS has a key role <strong>in</strong> assess<strong>in</strong>g the risks from obesity atthe national and local levels, and devis<strong>in</strong>g appropriate strategies to reduce itsimpact. But work is needed at the local level to develop and implement effectivepolicies to prevent overweight and obesity, and to tackle the wider healthimpacts of obesity through effective treatment programmes. In particular, theNHS needs to focus on identify<strong>in</strong>g and help<strong>in</strong>g those who are at high risk ofobesity. This would <strong>in</strong>clude target<strong>in</strong>g <strong>in</strong>terventions at the large proportion of thepopulation already <strong>in</strong> the "overweight" category, and at those groups where theprevalence of obesity is highest, such as Black Caribbean and Pakistani women.16 General practitioners and their teams can play a key role <strong>in</strong> assess<strong>in</strong>g the riskto patients, provid<strong>in</strong>g health promotion, and provid<strong>in</strong>g <strong>in</strong>dividual advice andonward referral to relevant specialists. However, these activities need to beundertaken on a more consistent basis across general practice than is currentlythe case. There are opportunities for identify<strong>in</strong>g and spread<strong>in</strong>g good practicemore widely.17 We recommend <strong>in</strong> particular that:nn<strong>in</strong> devis<strong>in</strong>g local strategies to reduce overweight and obesity, healthauthorities must have regard to the Health Development Agency's guidanceon which <strong>in</strong>terventions have proved most effective;health authorities should ensure that they set realistic milestones and targetsfor improv<strong>in</strong>g nutrition and diet, for promot<strong>in</strong>g physical activity and forarrest<strong>in</strong>g the ris<strong>in</strong>g trends <strong>in</strong> the prevalence of overweight and obesity. Theyshould also develop <strong>in</strong>dicators of progress <strong>in</strong> reduc<strong>in</strong>g health <strong>in</strong>equalitiesthrough <strong>in</strong>itiatives that target the population groups at highest risk;executive summary3
TACKLING OBESITY IN ENGLANDnnnthe Department of Health should commission an appraisal of theeffectiveness of <strong>in</strong>terventions for treat<strong>in</strong>g overweight and obese people,both with<strong>in</strong> general practice and through onward referral. This reviewshould <strong>in</strong>clude the potential role hospitals and specialist weight loss cl<strong>in</strong>icscan play <strong>in</strong> assessment and treatment, and whether access to such servicesshould be broadened;the Department of Health should build on the plan <strong>in</strong> the <strong>National</strong> ServiceFramework for coronary heart disease for a full assessment of risk factors tobe carried out <strong>in</strong> general practice. The Department should work with itspartners and the professional bodies to clarify the responsibilities of generalpractitioners and the wider primary care team for identify<strong>in</strong>g people at riskfrom excess weight;the Department of Health should liaise with the <strong>National</strong> Institute forCl<strong>in</strong>ical Excellence to draw together and ensure the effective dissem<strong>in</strong>ationof guidel<strong>in</strong>es for the management of overweight and obese patients <strong>in</strong>primary care. This report provides an <strong>in</strong>itial guide of what general practiceswould f<strong>in</strong>d useful.Ma<strong>in</strong> f<strong>in</strong>d<strong>in</strong>gs and recommendations on cross-Government <strong>in</strong>itiatives to prevent obesity18 We found a substantial amount of cross-departmental work <strong>in</strong> the areas that arecentral to address<strong>in</strong>g the ris<strong>in</strong>g prevalence of obesity - pr<strong>in</strong>cipally education,physical activity and diet. Much of this activity is targeted at schoolchildren.This promotes healthier lifestyles subsequently throughout adult life, andaddresses a section of the population for which obesity is becom<strong>in</strong>g an<strong>in</strong>creas<strong>in</strong>g problem.19 We conclude that there is a need for the departments <strong>in</strong>volved <strong>in</strong> this jo<strong>in</strong>twork<strong>in</strong>g to build on their successes and to <strong>in</strong>volve other partners at the nationaland local level to develop and implement cohesive strategies for prevention,which encompass adults as well as young people. At the national level, this istak<strong>in</strong>g place to an <strong>in</strong>creas<strong>in</strong>g extent, and departments should develop jo<strong>in</strong>tobjectives and performance targets relat<strong>in</strong>g to aspects of physical activity anddiet to ensure that this progress is consolidated. At the local level, healthauthorities are well placed to trigger such activity by develop<strong>in</strong>g HealthImprovement Programmes that <strong>in</strong>volve a wide range of other partners <strong>in</strong>schemes to <strong>in</strong>crease cycl<strong>in</strong>g, walk<strong>in</strong>g and physical recreation and to improvediet, such as through <strong>in</strong>creased consumption of fruit and vegetables.4execuitve summary
