Obesity in children: systematic review over a 6-year period, including the Covid-19 pandemic

Abstract

Although obesity is a frequently formulated diagnosis at all ages, due to the long-term projection of the consequences of this condition in children it is a real public health problem. The etiology of obesity is multiple and its complexity requires a multidisciplinary medical approach from which the psychological component cannot be omitted. Thus, diseases such as diabetes, dyslipidemias, cardiovascular diseases, sleep apnea syndrome, non-alcoholic fatty liver or neoplasia are encountered with a higher incidence in this category of individuals. During the COVID-19 pandemic, the isolation and, consequently, the reduction of access to ways of performing physical exercise increased the balance between caloric intake and caloric consumption resulting in the accumulation of surplus calories in the form of adipose tissue. The purpose of the present work is to emphasize the interest manifested by the medical scientific world regarding obesity in the pediatric population, in the pre-pandemic period, during the pandemic period and one year after its’ end (2018-2023). We performed systematic review of clinical studies on obesity in the pediatric population, including 98 articles published in the PubMed database. The number of studies published during the pandemic period (53) vs the number of studies published ex-pandemic (45), corresponds to a ratio of 1.17:1 in favor of the first. Obesity remains a research topic of major interest in early life, regardless of the coexistence of COVID-19.
