Children's nutrition: a global emergency Philip James IPA IDF IOTF IUNS WHF LSHTM and Chair of IOTF and the Presidential Council of the Global Prevention Alliance
Malnutrition: a continuing outrage TMRU, Kingston, Jamaica, Christmas 1966
Elimination malnutrition: a global deficit in policies and priorities UN Millennium report. James et al. Food & Nut Bulletin 2000, 21:Supplment 3 Potential response on the basis of Thailand's achievements % World Food Summit goal Desired UN response with major change in policies % underweight children in the world IFPRI Projections with free market mechanisms Millions of underweight & stunted schoolchildren
Projected overweight (incl. obesity) rates for school age children Wang and Lobstein, IOTF, 2006. e.g. China e.g. India % Prevalence e.g. US S.Arabia e.g. UK Global total Obese 74 mil. O/wt 287 mil. Global total Obese 74 mil. O/wt 287 mil.

The impact of inappropriate Western diets on most of the world's susceptible populations: health systems already overwhelmed Adapted from James et al. SCN Millennium Rep. Food & Nutrition Bulletin, 2000, 21, 3S. Early onset Type 2 Diabetes Reduced play and social isolation Reduced capacity to care for baby Disordered foetal nutrition Untimely / inadequate Early Weaning Frequent fast foods Inadequate physical activity Normal/high growth Woman o/w or obese Pregnancy Glucose intolerance/ diabetes Adolescent O/W-obese Child overweight Elderly Diabetes, strokes, heart disease, cancers arthritis Fat Baby High Birth Weight Poor school conditions Inadequate obstetric care Reduced job opportunities Inadequate health care system Abdominal obesity Rapid weight gain Reduced fertility; CVD, HT Cancers
The increasing risk of adult coronary heart disease if adults in childhood ( 7-13 yrs) had modest weight increases Copenhagen school children's study of 276,835 children measured from 1955 - 1960 with National Death and Hospital Discharge Registries. Hazard relates to one BMI Z score: linearly related to events at all ages but hazard ratio progressively increases with age during childhood. Baker, Olsen & Sorensen. NEJM 2007, 357: 2329-32
Fundamental changes in physical activity: inevitable and optional changes Inevitable: Rural to urban transition Labour changes; Mechanisation/computerisation of standard work; also home duties e.g. cooking, washing, cleaning Optional: Urban building policies: high intensity or US style sprawl? Road and community design Office & supermarket location policies Car policies versus preference for cyclists/pedestrians Policies on free spaces for children's play; lighting for safety e.g. for older people Park/leisure/sports facilities/school PA lessons Ease of transport of perishable foods into towns/cities
Obesity: time watching TV overwhelms leisure activity in Australia Adapted from Salmon, Bauman et al IJO 2000;24:600-606 Adapted from Salmon, Bauman et al IJO 2000; 24:600-606 TV time Increasing TV time Leisure time sport & activity Average BMI for each group 28 27 26 25 24 23 22 21 Total daily physical activity High Moderate Low Inactive
e.g. Focus on Health Education; campaigns selectively help upper socio-economic groups Individual responsibility Changes to the "toxic" environment Adapted from Puska P, 2001 Progressively adapt all towns/cities to favour pedestrian/cycling as norm with car restrictions Nutritional standards for food in all government facilities/schools; eliminate trans fats; catering on Finnish scale: fruit + veg. within meal costs Limit/abolish all marketing to children Selectively increase costs of high fat/sugary products; soft drinks Social/employment/medical policies for breast feeding as the norm Complementary approaches to obesity & chronic disease prevention

Strategies for combating childhood obesity Protecting children at least up to 12 yrs: Breast feeding Breast feeding Proper weaning practices Proper weaning practices Regulated child minders: food and play Regulated child minders: food and play Legislate on all forms of marketing: TV, radio, text messages, internet, food product labelling, games etc. Legislate on all forms of marketing: TV, radio, text messages, internet, food product labelling, games etc. School environment : major changes needed School environment : major changes needed Supermarket practices Supermarket practices Pricing policies : affect school aged children Pricing policies : affect school aged children Policies on density of available fast foods outlets in town centers Policies on density of available fast foods outlets in town centers

Five Practical Priorities Major drive to increase/ sustain breast feeding Major drive to increase/ sustain breast feeding: facilities at work important; maternal leave + cultural change Marketing restrictions Marketing restrictions (not just TV advertising) - statutory for children & adolescents: rights of child extend to 18 yrs Control of food Control of food in nurseries, all school facilities and school environment: avoid choice - all foods of high nutritional quality + facilities to allow spontaneous play - not TV Fruit and vegetable availability Fruit and vegetable availability routine in canteens and restaurants (within main cost) Transformation of physical facilities for spontaneous & leisure time activity Transformation of physical facilities for spontaneous & leisure time activity: urban design changes with novel traffic policies; pedestrian only areas immediately adjacent to houses/apartments
