One of the great masterworks of Pende art in Western collections, this Mbangu mask represents the bewitched him. It dances to the song, “We look on (unable to help), the sorcerers have bewitched him.” The masker wears a humpback from which an arrow extends. The arrow refers to the popular image of sorcerers “shooting” their prey with invisible arrows when they cast their spell. The metaphor communicates the perception of sudden onslaught in illness or misfortune, just as we might say, “It came out of the blue.” Mbangu is “bewitched”; however, since the Pende worldview attributes almost all illness and personal misfortune to the malice of others, what is really at issue is chronic illness or disability and our response to it. If he does not carry a bow and arrows, the dancer usually avails himself of a cane to indicate his physical weakness. The black-and-white division of his face refers to the scars of someone who fell into the fire due to epilepsy or some other medical condition. This sculptor has also depicted traces of smallpox on the black eyelid, and the face is pulled down on one side due to a paralysis of the facial nerve. Sculptor and performer collaborate to make Mbangu a composite sign of illness and disability, of all the misfortunes that can befall someone. What then is to be our response to Mbangu? Some sculptors render the mask comedic, but this work conveys an extraordinary delicacy and sympathy by contrasting the gentle perfection of the features on one side with the systematic distortion on the other. This sculptor responds to the widespread version of Mbangu's song: “Do not mock your neighbor, do not laugh at your brother, the sorcerers have bewitched him.” In other words, anyone can fall prey to misfortune; it could hap- pen to you. Our brother, our neighbor, deserves our support.

Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Bruce M. Alberts is president of the National Academy of Sciences. The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. William. A. Wulf is president of the National Academy of Engineering. The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Kenneth I. Shine is president of the Institute of Medicine. The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Bruce M. Alberts and Dr. William. A. Wulf are chairman and vice chairman, respectively, of the National Research Council. www.national-academies.org About this PDF file: This new digital representation of the original work has been recomposed from XML files created from the original paper book, not from the original typesetting files.

PREFACE ix Preface The continuing existence of gross disparities in health between affluent and poorer countries is becoming a major challenge for policy makers in the new millennium. While the link between poverty and disease is well established and has been recognized by public health leaders and social reformers for a century and a half, the complexity of this relationship has become apparent only in the last several decades as national governments and international organizations have accorded health increasing priority in development programs. It is now widely accepted that socioeconomic development and population health must advance together to be sustainable in the long term. Improvements in population health are not merely or even necessarily a by-product of economic growth. They are a prerequisite and a driving force of economic and social productivity. Reductions in maternal and infant mortality, improvements in nutrition and environmental sanitation, and control of communicable diseases have made important contributions to economic growth. Conversely, high levels of preventable morbidity and mortality, survival with chronic disability, reduced quality of life, and widespread demoralization are a drain on society's resources and impede overall development. For several decades, investments in health in the context of national and international development strategies have targeted primarily the major communicable diseases, malnutrition, and poor sanitation in low-income countries. A number of such programs have successfully lowered infant mortality rates and, as a result, increased life expectancy at birth. However, the net effect of such gains has been largely offset by the epidemiological transition from a About this PDF file: This new digital representation of the original work has been recomposed from XML files created from the original paper book, not from the original typesetting files.
