6 Allattamento al seno e prevalenza di sovrappeso e obesità in 9357 bambini di età compresa tra 5 e 6 anni (Von Kries R et al, BMJ 1999; 319:147) sovrappeso : BMI> 90 o percentile per età e sesso obesità: BMI>97 o percentile per età e sesso

7 Breastfeeding and prevalence of overweight° in over 15000 adolescents aged 9-14 years. (adapted from Gillmann et al, JAMA 2001:285:2461-67) °Overweight was BMI>95th percentile for age and sex

9 Life expectancy at birth in EU member states has increased by over 6 years between 1980 and 2010. On average across the European Union, life expectancy at birth for the three-year period 2008-10 was 75.3 years for men and 81.7 years for women. Most European countries have reduced tobacco consumption via public awareness campaigns, advertising bans and increased taxation Alcohol consumption has also fallen in many European countries. In the European Union, 52% of the adult population is now overweight and 17% is obese. The obesity rate has doubled since 1990 in many European countries. Obesity tends to be more common among disadvantaged social groups, and especially women

10 Il latte materno 1. Basso apporto proteico (< 1 g / 100 ml; latte vaccino  3.5 g/100 ml, formule non meno di 1.2- 1.4 g/100 ml) 2. Ottimale rapporto energia/proteine 3. Presenza di numerosi fattori anti-infettivi 3. Grassi e carboidrati con valore funzionale (LCPUFA, oligosaccaridi)

11 Ljung K et al

12 Formule : quali Formule standard  fino a 6 o 12 mesi Formule di seguito  tra 6 e 12 mesi Formule di crescita  2 e 3 anni

13 Elementi chiave delle formule 1.Proteine (quantità e qualità) 2.Grassi (quantità e qualità  acido linolenico, acido docosaesaenoico) 3.Qualità carboidrati (digeribili/non digeribili) 4.Minerali e micronutrienti (ferro, zinco, calcio, Vitamina D), altri composti “funzionali”

14 Is Cows' Milk Harmful for a Child's Health ? Key-note lecture - NUTRITION Carlo Agostoni Fondazione IRCCS Cà Granda Ospedale Maggiore Policlinico University of Milan, Italy CHAIR PERSON: Dominique Turck, Lille, France

15 Conclusions: Cow’s Milk harmful? Negative effects on iron status up to 9-12 months, then no negative effects if adequately complemented with iron enriched foods Lactose intolerance  easily managed Allergy to WCM proteins may be transient. Atopics may independently be at risk of poor growth A cause-effect relationship with T1D is not established, and the same for ASDs Cow’s milk stimulates IGF-1 and may affect linear growth, but associations with non-communicable diseases is still not convincing

16 Conclusions: Cow’s Milk Safety From 12 months of life onwards Up to around 500 mL per day 250 mL in lactose intolerants Fat-reduced milks after 24-36 months on individual basis

37 Energy costs of fat and protein deposition in the human infant Am J Clin Nutr 1988; 48:951 Total energy requirement for deposition  1.17 kJ/kJ (kcal/kcal) deposited for fat (ie, 1 kJ deposited and 0.17 kJ expended for deposition, and 2.38 kJ/kJ (kcal/kcal) for protein. The metabolizable-energy requirement for weight gain during infancy was calculated (range, 12.2-25.1 kJ/g, or 2.9-6.0 kcal/g; means, 18.7 kJ/g, or 4.5 kcal/g) from the energy costs of fat and protein deposition and published information on changes in body composition during the first year of life.

38 Energy expended by low birth weight infants in the deposition of protein and fat. Pediatr Res 1997 ;41:584 Using multiple regression analysis of energy expenditure against protein stored, and metabolizable energy, the energy expended in the deposition of protein was calculated to be 5.5 kcal/g +/- 1.1 kcal/g (SE) and the energy cost of fat deposited was 1.6 kcal/g +/- 0.3 kcal/g (SE).

47 Quando introdurre il latte vaccino ? Non prima del dodicesimo mese  latte materno fino ad un anno, anche più a lungo Dopo il 12° mese può essere introdotto il latte vaccino (limitare la quantità?) Tra il 12° ed il 36° mese una formula di crescita - GUM- può migliorare il bilancio dei nutrienti  effetti funzionali non noti, mancano dati “diretti” su parametri ematici ATTENZIONE al bilancio energetico nel suo complesso  puo’ vanificare ogni altro tentativo di riequilibrio qualitativo e quantitativo
