Abstract
Objective: To carry out a narrative review of childhood obesity and its repercussions on the most prevalent respiratory diseases in childhood. Bibliographic review: The prevalence of childhood obesity has been increasing progressively in recent decades. Excess weight is associated with cardiometabolic dysfunctions, respiratory diseases and sleep, and many studies have shown that it is an avoidable factor and modifier of some disorders, such as obstructive sleep apneia (OSA) and asthma, that affect the pediatric band very often. A relação da obesidade e OSA and bidirectional, cyclical, wave a piora de uma, reflect na outra. Or pro-inflammatory state due to obesity at the airways, causing a non-allergic pulmonary inflammation response, as well as the effect of fat accumulation in the thoracic and abdominal regions, affecting respiratory dynamics, making it difficult or controlling asthma. Several routes favor the release of cytokines due to or excess intake of fat, from intestinal microbiota, liver tissue, peripheral adipose tissue and vascular endothelium. Final considerations: With a high prevalence of childhood obesity and days that soften its influence, increasingly young adults are suffering with cardiovascular, metabolic and respiratory disorders.
