ISMAEL PERDOMO PEDIATRA

When discussing childhood obesity, we often think first about weight, body image, or future diabetes risk. Yet one of its most important and underestimated comorbidities is metabolic dysfunction-associated steatotic liver disease, now termed MASLD. This condition reflects fatty liver in the setting of metabolic abnormalities and has become a clinical expression of the systemic damage linked to excess adiposity. In pediatrics, its importance is growing because it is no longer a subspecialty rarity, but an increasingly common condition in children and adolescents with obesity.   Medically, MASLD is not a benign incidental finding. It is associated with insulin resistance, dyslipidemia, hypertension, chronic low-grade inflammation, and progression to more severe liver disease. The  Hepatology  article emphasizes that pediatric MASLD is linked to major childhood comorbidities and a 40-fold higher risk of early mortality in young adulthood, and notes that it has become th...

One of the most important debates in current pediatric nutrition is no longer only how much children eat, but how much of their diet comes from ultraprocessed foods. These industrial formulations often concentrate free sugars, sodium, low-quality fats, additives, and high energy density while displacing fresh or minimally processed foods. In clinical practice, frequent intake is associated with poorer diet quality and greater difficulty sustaining protective eating patterns during childhood.   Childhood obesity must be understood as a chronic disease in which the food environment plays a decisive role. From a pathophysiologic perspective, ultraprocessed foods may promote higher glycemic load, lower satiety, hyper-palatability, and repeated exposure to dietary patterns that favor positive energy balance. Epidemiologically, this matters because exposure starts early and overlaps with rising obesity prevalence. WHO continues to describe pediatric overweight and obesity as a growi...

Modern well-child care should not be limited to tracking weight, length, and vaccines; it must also anticipate the everyday behaviors that shape future metabolic risk. In early infancy, practices such as persistent nighttime feeding without clear need, pressure to finish the bottle, screen use during feeding, and poor sleep routines can become early obesogenic factors. This study is important because it translates obesity prevention into real infant life and shows that pediatric primary care can intervene before overt excess weight appears.   From a pediatric standpoint, the issue is not only how many calories an infant receives, but how appetite self-regulation, sleep patterns, and caregiver-child interaction are established. Childhood obesity is a long-trajectory disease, and its pathophysiology includes disrupted satiety signaling, nonresponsive feeding, early sedentary behaviors, and sleep-related circadian disruption. Current epidemiology makes this stage impossible to ig...

Childhood obesity does not begin when a child starts school or when excess weight becomes visible. Its biological and behavioral trajectory often starts before birth and consolidates during the first 1000 days of life, from preconception to age two. This concept is highly relevant in preventive pediatrics because it shifts the focus from late correction to early, family-centered, population-level prevention. The EndObesity Consortium review places that idea at the center of current scientific discussion: if we want to alter the obesity epidemic, we must intervene before the phenotype is fully expressed.   Medically, childhood obesity is a chronic, multifactorial, relapsing disease. Its epidemiology no longer allows us to treat it as a minor issue: it affects hundreds of millions of children worldwide and is linked to hypertension, insulin resistance, dyslipidemia, obstructive sleep apnea, metabolic dysfunction-associated steatotic liver disease, and long-term cardiometabolic r...
