OBJECTIVE:: Overweight/obesity prevalence has increased dramatically worldwide. Recent evidence suggests sleep deprivation/fragmentation, fructose-exceedingly rich diets and exposure to endocrine disruptors (e.g., bisphenol A, BPA) as emerging additional factors involved in pathomechanisms and in the treatment-resistance of obesity and its complications. Our study focuses on these factors for further preventive/therapeutic approaches in paediatric obesity. METHODS:: Fifty-four Italian children [Cases: n = 31 overweight/obese; Controls: n = 23 normal weight] were clinically/anthropometrically characterised. Parents completed questionnaires on the relationship between obesogenic factors and childhood obesity. BPA was measured by GC/MS-MS on early morning urine samples. Correlations between the continuous variables were analysed using Spearman's Rank Correlation. RESULTS:: Sleep deprivation/fragmentation, nocturnal breathing problems and daytime sleepiness increased with increasing BMI, correlating with the presence of clinical markers of metabolic syndrome (e.g., acanthosis nigricans). Frequency of sugar-enriched drink consumption and the amount of fructose per portion and/or per week increased paralleling the ponderal excess and all the other anthropometric parameters. In the entire sample population, free and total BPA levels increased paralleling the BMI increase (r > 0.8), whereas the conjugate demonstrated the opposite trend. The re-use of disposable plastic showed a positive correlation with urinary BPA levels. CONCLUSIONS:: Despite its exploratory nature, the results of our pilot study confirm the close relationship between certain factors and paediatric obesity, underscoring their role as emerging targets for prevention and therapy.

Abstract

OBJECTIVE:: Overweight/obesity prevalence has increased dramatically worldwide. Recent evidence suggests sleep deprivation/fragmentation, fructose-exceedingly rich diets and exposure to endocrine disruptors (e.g., bisphenol A, BPA) as emerging additional factors involved in pathomechanisms and in the treatment-resistance of obesity and its complications. Our study focuses on these factors for further preventive/therapeutic approaches in paediatric obesity. METHODS:: Fifty-four Italian children [Cases: n = 31 overweight/obese; Controls: n = 23 normal weight] were clinically/anthropometrically characterised. Parents completed questionnaires on the relationship between obesogenic factors and childhood obesity. BPA was measured by GC/MS-MS on early morning urine samples. Correlations between the continuous variables were analysed using Spearman's Rank Correlation. RESULTS:: Sleep deprivation/fragmentation, nocturnal breathing problems and daytime sleepiness increased with increasing BMI, correlating with the presence of clinical markers of metabolic syndrome (e.g., acanthosis nigricans). Frequency of sugar-enriched drink consumption and the amount of fructose per portion and/or per week increased paralleling the ponderal excess and all the other anthropometric parameters. In the entire sample population, free and total BPA levels increased paralleling the BMI increase (r > 0.8), whereas the conjugate demonstrated the opposite trend. The re-use of disposable plastic showed a positive correlation with urinary BPA levels. CONCLUSIONS:: Despite its exploratory nature, the results of our pilot study confirm the close relationship between certain factors and paediatric obesity, underscoring their role as emerging targets for prevention and therapy.
