With the COVID-19 pandemic in 2020, ensuring adequate nutrition to secure the growth and well-being, particularly of infants and young children, faced new obstacles. For this publication, an international group of experts in nutrition, metabolism, gastroenterology, endocrinology, and auxology have selected some of the most important papers published between July 2019 and June 2020, exploring topics on children's growth. Each paper is supplemented with editorial comments aiming to highlight lessons that can be learnt. This seventh edition of the yearbook provides a significant contribution to the understanding and management of various aspects of nutrition and growth. It is intended to help healthcare providers in all related areas to study and treat key issues in this field.
