Acknowledgments

Data collection and analyses were supported by National Institutes of Health (NIH) grant HD22440 and by Pew Charitable Trusts grant 90-00210-000. The NIH study was a collaborative effort involving investigators from several institutions: R. Martorell (principal investigator, then at Stanford University, now at Cornell University), J. Rivera (Institute of Nutrition of Central America and Panama, Guatemala City), E. Pollitt (University of California, Davis), and J. Haas (Cornell University).

We gratefully acknowledge the valuable comments on earlier versions of this manuscript from Curt Acredolo, Janet Peerson, Henry Ricciuti, and the anonymous reviewers. Their time and thoughtful input are greatly appreciated. We also wish to acknowledge the contributions made by Dr. Robert Klein. As director of the longitudinal phase (1969-1977), he built the basis for the follow-up study that began in 1988. An earlier comprehensive discussion among experts in the International Dietary Energy Consultative Group contributed substantially to the data presented in this Monograph.
