Sleep and obesity. An introduction

The paper focuses on the relationship between poor sleep quality/quantity and obesity and aims to document and support the progresses in this field, bringing new contributions to several questions that are still open in the extant literature. The work also introduces to the Topical Collection ‘‘Sleep and Obesity’’ which will cover the contribution of poor sleep in the etiology of obesity in both humans and animals, the epidemiological and diagnostic features that relate poor sleep to obesity as well as the associated features and the factors that could moderate or mediate this relationship. The topical collection is aimed to provide a wide evidence base for clinicians, and researchers and all readers interested in this area
