The IUNS Bellagio meeting on the nutrition transition in the developing countries. THE RELATIVE BURDEN OF DISEASE DUE TO UNDER- AND TO OVER-NUTRITION: EVIDENCE FROM BRAZIL Carlos A. Monteiro (carlosam@usp.br) São Paulo University, Brazil
THE BURDEN OF DISEASE DUE TO UNDER- AND TO OVER-NUTRITION IN THE DEVELOPING COUNTRIES • What is the present situation? • What has been the pace of change? Is over-nutrition replacing (or adding to) under-nutrition? • Are young children, old children, and adults similarly affected? • Are distinct social classes equally affected?
THE BURDEN OF NUTRITIONAL DISEASES:COMPONENTS AND DEFINITIONS • The under-nutrition burden: nutritional imbalances caused by insufficient consumption and/or excessive expenditure of energy and nutrients. • The over-nutrition burden: nutritional imbalances caused by excessive consumption and/or insufficient expenditure of energy and nutrients.
BRAZIL • Repeated national anthropometric surveys in the 70’s, 80’s , and 90’s. • Great historical development contrasts between the poor northern regions and the rich southern regions. • Great income disparities between and within the regions.
GDP PER CAPITA (BRAZIL, 1994) NORTH US$ 2,299 NORTHEAST US$ 1,635 CENTERWEST US$ 3,650 SOUTHEAST US$ 4,490 SOUTH US$ 3,983
What is the relative burden of disease due to under- and to over-nutrition? in the (less developed) northeastern Brazil in the (more developed) southeastern Brazil
INDICATORS EMPLOYED TO ASSESS UNDER- AND OVER-NUTRITION • In young children (1-4 y) height-for-age < -2 z; weight-for-height > + 2 z; international growth reference • In old child/adolescents (10-17 y) BMI < 5th centile; BMI > 95th centile; the 1989 survey as the reference distribution • In adults (20 y and +) BMI < 18.5 kg/m2; BMI 30.0 kg/m2

TRENDS IN THE RELATIVE BURDEN OF UNDER- AND OVER-NUTRITION Brazilian young children: 1975-1996
TRENDS IN THE RELATIVE BURDEN OF UNDER- AND OVER-NUTRITIONBrazilian old child/adolescents: 1975-1997
TRENDS IN THE RELATIVE BURDEN OF UNDER- AND OVER-NUTRITIONBrazilian adults: 1975-1997
Are distinct social classes equally affected by the nutrition transition?
Is the under-nutrition gap between poor and rich being eliminated ? Income groups: the 25% poorest and the 25% richest families in each region.
TRENDS IN UNDER-NUTRITION GAPSlower income vs. upper income young children
Is the over-nutrition gap between rich and poor being reduced (or even reversed) ? Income groups: the 25% poorest and the 25% richest families in each region.
TRENDS IN OVER-NUTRITION GAPSlower income vs. upper income adult men
TRENDS IN OVER-NUTRITION GAPSlower income vs. upper income adult women
Is the net effect of the nutrition transition positive or negative to the poor? Income groups: the 25% poorest and the 25% richest families in each region.
TRENDS IN UNDER- + OVER-NUTRITION lower income vs. upper income young children
TRENDS IN UNDER- + OVER-NUTRITION lower income vs. upper income adult women
