The prevalence of childhood obesity has tripled in the United States over the last 25 years, and in addition to increased risks of many chronic diseases, obesity may also be linked to lower skill attainment, poor social competency, and poorer labor outcomes. Any causal links between obesity and human capital accumulation could have important consequences for both health and economic well-being over the life course. We investigate the association of obesity and cognitive and non-cognitive outcomes among US children and adolescents aged 5 to 19 using the Child Development Supplement of the Panel Survey of Income Dynamics. We perform OLS and individual fixed effects regressions to address unobserved time invariant heterogeneity in the relationship between overweight/obesity and abilities. Results provide limited support for the hypothesis that obesity negatively affects non-cognitive but not cognitive outcomes and suggest that discrimination rather than a biological mechanism contributes to negative outcomes found in the literature on adults.

Obesity and metabolic syndrome in a diverse pediatric kidney transplant population: which anthropometric measure best predicts arterial stiffness?
Pediatr Nephrol
January 2025
Nephrology, Children's National Hospital, 111 Michigan Avenue NW, Washington, DC, 20010, USA.
Background: Obesity and metabolic syndrome (MS) accelerate arterial stiffening, increasing cardiovascular (CV) risk after transplant. BMI is limited by inability to differentiate muscle, fat mass, and fat distribution patterns. The aim of this study was to identify the best anthropometric measure to detect arterial stiffness as assessed by pulse wave velocity (PWV) in a racially diverse pediatric transplant population.

Department of Pediatric Cardiology, Ankara Bilkent City Hospital, Ankara, Türkiye.
Background: We aimed to evaluate how the parameters used in the diagnosis of metabolic syndrome (MetS) and parameters such as epicardial adipose tissue (EAT) thickness, insulin resistance (IR), and serum uric acid (SUA) are affected according to the severity of obesity.
Methods: A total of 120 obese patients aged 10-18 years were classified as class 1-2-3 according to their body mass index (BMI) score. SUA was measured and oral glucose tolerance tests were performed on all patients.

Design: Analysis of data from two cross-sectional surveys.
Setting And Participants: 921 children from 2016 to 2021 and 1505 adults from 2018 to 2021 living in iodine-sufficient areas from Tianjin, China were recruited.
Prevalence and Predictors of Overweight and Obesity Among School-Aged Children in the Country of Georgia: A Cross-Sectional Study, 2022.
BMC Nutr
January 2025
Department of Epidemiology and Biostatistics, Tbilisi State Medical University, Tbilisi, Georgia.
Background: Childhood overweight and obesity are significant global public health challenges that affect approximately 340 million children worldwide. In Georgia, the prevalence of childhood obesity is alarming, with approximately 28% of 7-year-old children classified as overweight or obese in 2019. This study aimed to investigate the key factors associated with overweight and obesity among school-age children in Georgia.

Cardiovasc Diabetol
January 2025
Department of Endocrinology and Nutrition, Virgen de la Victoria University Hospital, 29010, Málaga, Spain.
Background: The prevalence of obesity and type 2 diabetes mellitus (T2DM) is rising globally, particularly among children exposed to adverse intrauterine environments, such as those associated with gestational diabetes mellitus (GDM). Epigenetic modifications, specifically DNA methylation, have emerged as mechanisms by which early environmental exposures can predispose offspring to metabolic diseases. This study aimed to investigate DNA methylation differences in children born to mothers with GDM compared to non-GDM mothers, using saliva samples, and to assess the association of these epigenetic patterns with early growth measurements.
