Article Abstract
Objective: The impact of in utero exposure to maternal overweight and obesity on offspring metabolic health is well documented. Neurodevelopmental outcomes among these children are, however, less well studied. To address this gap, the current study investigated brain function among 4- to 6-year-old children exposed to maternal overweight or obesity during gestation compared with that of children born to mothers with healthy BMI in pregnancy.
Methods: Resting-state functional magnetic resonance imaging was used to study neuronal activity and connectivity during a passive viewing task (movie) among 101 typically developing children enrolled in the Healthy Start study, a longitudinal prebirth cohort in Colorado.
Results: Forty-nine children (48%) were exposed to maternal overweight or obesity in utero (mean age = 5 years, SD = 0.9). Children born to mothers with overweight or obesity demonstrated hyperactivity in the left posterior cingulate cortex and hypoactivity in the dorsal anterior cingulate and the supplementary motor area (P < 0.05 for all). Children born to mothers with overweight or obesity also showed ubiquitously weaker brain connectivity (P < 0.05 for all).
Conclusions: These novel results suggest altered brain function among children exposed to maternal overweight and obesity in utero.

Socioeconomic differences in the cost-effectiveness of a telephone-based intervention for obesity prevention in early childhood.
Int J Obes (Lond)
September 2025
Sydney School of Public Health, Faculty of Medicine and Health, The University of Sydney, Sydney, NSW, Australia.
Objectives: This study investigated the cost-effectiveness of an early childhood obesity prevention intervention providing telephone and short message service (SMS) support to mothers of children aged 2-4 years by socioeconomic position (SEP).
Methods: A model-based SEP-specific economic evaluation of the intervention was conducted. SEP-specific intervention costs and effects at age 5 years were derived from the trial data and applied to a cohort of 4- to 5-year-old Australian children.
Association of anthropometric parameter with myopia in children and adolescents: A systematic review and meta-analysis.
Int J Obes (Lond)
September 2025
Department of Ophthalmology, The Second Affiliated Hospital of Anhui Medical University, Hefei, 230601, China.
Objective: To systematically evaluate the association between anthropometric parameter and myopia in children and adolescents.
Methods: PubMed, Web of Science, EBSCO, Embase, CNKI, CBM, WanFang Data, and VIP databases were searched from inception to June, 2025. We collected cross-sectional studies on the association between anthropometric parameter and myopia in children and adolescents aged 0-25 years, including body mass index (BMI) and weight-adjusted waist index (WWI).

Osteoarthritis (OA) is the most prevalent and disabling joint disease, while adipose-derived stem cells (ASCs) have emerged as a promising therapeutic option in pre-clinical studies. However, the therapeutic efficacy of ASCs may be influenced by the source of these cells, especially in obese patients. This study compared the effects of intra-articular injections of ASCs from wild-type (WT) and ob/ob (OB) mice.

European survey on metabolic and cardiovascular risk in Cushing syndrome.

Background: Cushing's syndrome (CS) is associated with increased metabolic and cardiovascular (CV) risk factors and morbidities. Evidence-based guidelines for the management of these issues in active or remitted CS are not available, so best practice is derived from guidelines developed for the general population. We aimed to evaluate the awareness and practice variation for CV comorbidities of CS across Reference Centres (RCs) of the European Reference Network on Rare Endocrine Conditions (Endo-ERN).
