Pediatric obesity – time to act as early as possible

Abstract

There has been a global increase in the average body mass index (BMI) in children and an alarming trend of increasing weight among the youngest children in recent decades. Childhood excess weight and obesity result in premature adult mortality and morbidity. Obesity is not only a risk factor for other diseases but is also a complex, multifactorial disease in its own right, linked to a genetic predisposition influenced by an increasingly permissive environment from intrauterine life throughout childhood and adolescence into adulthood. Knowledge of the prevalence of obesity from the earliest life stages and its trajectory is essential to raise awareness of the risks at each stage and to indicate the potential age of prevention and intervention. Taking effective anti-obesity measures in children, both preventive and therapeutic, is now a necessity, with successful interventions used to decrease body weight and thus reduce health consequences. Identified risk factors in the first 1,000 days of life and even earlier, before conception, suggest that this is a key period for the development of overweight and obesity, and it appears to be the best time for preventive action. The growing phenomenon of obesity among children requires not only prevention but also integral treatment. Lifestyle change intervention programs are considered key to the treatment of childhood obesity. Obesity trajectories, the higher effectiveness of applied interventions observed in younger age groups, and the dependence of the risk of developing complications on the duration of obesity confirm the need for early diagnosis and treatment of obesity in children from an early age. The main aim should be to prevent the onset of obesity, thus reducing the future health, social, and financial consequences.
