WORLD HEALTH ASSEMBLY MAY 1998 
     
    The World Health Assembly in Geneva signalled another important step towards wider recognition of the global epidemic of obesity. 

    The issue was raised most notably by the Maltese delegation calling for more attention to be given to the issue. 

    An optimistic WHO 1998 report noted that people are healthier and living longer than ever but made several references to the significant impact that obesity is making on global health.

      Obesity is becoming one of the most important 
    contributors to ill health (p87)
     
    HIGHLIGHTS- facts, figures and quotes from the WH98 report: 
     
     
     
     
    • Food supply has more than doubled in 40 years (p1)
    • Average dietary energy supply (calories per capita) has risen by 20 per cent (p130)
     
     
       
      YEAR Energy supply
      1963 2,300
      1971  2,440
      1992  2,720 
      2010  2,900
       
     
       
      Population with access to 2,700 calories per day energy supply is rising exponentially (p130)
       
       
      196971  145million
      1990-92  1,800 billion
      2010 2,700 billion
       
       
      Diabetes cases will double from 143 million in 1997 to 300 million in 2025 largely because of dietary and other lifestyle factors (p5)
      Severe overweight will reach a corresponding level of 300 million by 2025 (p132) 
       
       
     
    QUOTE "In developing countries, as their economies grow, noncommunicable diseases will become more  prevalent, largely because of the adoption of  "western" lifestyles and their accompanying risk factors -  smoking, high-fat diet, lack of exercise." p5
     
     
     
    The WHO report pinpointed population ageing, unhealthy diets, obesity and sedentary lifestyles as four main factors explaining the alarming upward trend in diabetes mellitus, identified as a particular threat to developing nations. It noted that 20 years ago diabetes was considered an uncommon disease: (p91) 

    "Although diabetes manifests itself most commonly in adult life, there is growing evidence that its origins lie much earlier and are related to inappropriate dietary patterns and exercise habits.  World-wide, substantial increases in the frequency of obesity are occurring, in many cases at a relatively early age. Obesity is closely related to diabetes."   (p91) 

    The Report warned: "The extent to which young people are involved in physical activity is a growing concern in developed countries. Obesity is increasing, especially in the younger age group. Nutritional problems, especially over consumption of fats and sugars, are taking their toll." (p82) 
     

     
     
     
     
    CHILDHOOD OBESITY 
    CHILDHOOD OBESITY is emerging as a global problem, according to the report. Data from 79 developing countries and a number of industrialized countries suggest that about 22 million children under the age of 5 are overweight. (p69)
     
     
    QUOTE 
     
    "The result of scientific research continues to support the role of diet in the development of those diseases most responsible for mortality in the developed world..............The dynamic relationship between modifications in children's diets and sequential changes in their health as adults is beginning to emerge." (p73/74)
     

     
     

    "Obesity affects almost 10% of schoolchildren in industrialized countries and high rates are also emerging in some of the developing ones. Some 30 per cent of obese children become obese adults." (p69) 

    The Health of Youth Study found that 74% of 15-year-old boys studied exercised vigorously more than twice a week outside school, but only 52% of girls exercise twice weekly and were less active between the age of 11 and 15. (p82) 

    The WHO Executive Board report to the WHA also focussed on the issue of childhood obesity and give differing estimates for adult obesity :   
     
    "While millions remain undernourished, there is a growing epidemic of obesity in children and adults, especially in industrialized countries, but also in developing countries with fast growing economies. An estimated 22 million children under five years of age are significantly overweight (>2 standard deviation above reference median weight for height). 
     
    "Obesity in children is a major risk factor for obesity in adults, which in turn affects an estimated 286 million people. It is a significant risk factor in the huge burden of morbidity and mortality, owing to cardiovascular disease, hypertension, stroke, diabetes (type 2), some cancers, liver disease, gall-bladder disease, and accidents. WHO organized a major consultation on obesity and, in view of the magnitude of the problem, both regular global reporting and effective national public health nutrition strategies are urgently needed." 
     
    The WH98 report contrasted the problems of underweight and overweight and forecast that 300 million adults will be severely overweight by 2025: (p132) 

    "Growth in the number of severely overweight adults is expected to be double that of underweight adults during 1995-2024.  In order to assess the implications of these trends for the future health of mankind, the following figures should be considered: excess adult mortality in 1995 attributable to undernutrition is estimated at about 0.5 million deaths and to overnutrition about 1 million; mortality rates increase by about 25% and 100% respectively in underweight and overweight persons." (p132) 

    The report included an underweight/overweight index showing the Russian Federation at the top of the league (BMI>25), ahead of the UK, although the table omitted any reference to the USA. (p131) 

    "Obesity is also a significant risk factor for a range of serious noncommunicable diseases and conditions. WHO has initiated a review of associated morbidity and mortality with a view to developing guidelines for members states on obesity prevention and management. (p69) 

    "Improved prevention therapy for childhood obesity are the most cost-effective approaches to reduce morbidity and mortality due to obesity in adulthood; three potential approaches for the preventive interventions to deal with this problem are reduction in dietary intake, increase in the energy spent on activity and reduction in inactivity.(p70) 

    "Children with potentially lethal complications of obesity such a sleep apnoea require rapid and sustained weight reduction. One possible approach in children is a carbohydrate free diet under careful monitoring and follow-up. The role of drugs in the treatment of obesity is not clear. Some interventions aimed at both parents and children have been successful (e.g. modifications in diet, lifestyle activities and behaviour.)" (p70)
