It is a well-known fact that children's growth depends on the quality of their nutrition. However, the mechanisms of fetal and child growth and their interactions with nutrition have not yet been fully elucidated and still pose a challenge to those engaged in the field. Exchanging concepts and knowledge among professionals of various disciplines thus remains very important. This second 'Yearbook' provides an update on the research published between 2013 and 2015. An international team of experts presents papers that shed light on the mechanisms of interaction between nutrition and growth, and provide insight to the readers. Each paper is briefly summarized and supplemented with editorial comments which evaluate the clinical importance of each article and discuss its application.This 'Yearbook' is an important tool for practicing physicians, including pediatricians, subspecialists in pediatric gastroenterology, metabolism and nutrition, and endocrinology. Nutritionists and dieticians, as well as other health professionals involved in the care of children, will also find this to be a useful resource.
