Growth, Maturation and Body Composition documents one of the most remarkable and significant long-term studies in the field of human biology. The Fels Longitudinal Study is the longest, largest and most productive serial study of human growth, maturation and body composition. This book shows how data collected from more than 1000 participants during the past 60 years have been analysed to test a wide range of hypotheses, and describes how the findings have led to the development of improved research methods. Topics covered include the management and analysis of data, prenatal, familial and genetic studies, physical growth, development and maturation, bones and teeth, body composition, and risk factors for cardiovascular disease. With more than 1000 specialised publications of Fels data to date, the present book provides a unique overview of this fascinating research program, which will be of interest to a wide range of researchers, including those in the fields of physical anthropology, nutrition science, pediatrics, gerontology, epidemiology, endocrinology, human genetics, as well as statistics.
