Insights
Higher socioeconomic deprivation is linked to more severe paediatric metabolic dysfunction-associated steatotic liver disease (MASLD). This study found increased liver enzyme levels and fibrosis in children with higher social deprivation scores.
Area of Science:
- Pediatric Gastroenterology
- Hepatology
- Public Health
Background:
- Metabolic dysfunction-associated steatotic liver disease (MASLD), previously known as non-alcoholic fatty liver disease (NAFLD), is increasingly prevalent in children.
- The association between socioeconomic status and MASLD severity in pediatric populations is not well understood.
Purpose of the Study:
- To investigate the relationship between social deprivation and the clinical and histological characteristics of pediatric MASLD.
- To evaluate differences in MASLD severity markers based on socioeconomic factors in urban children.
Main Methods:
- Retrospective analysis of 277 pediatric patients (≤18 years) diagnosed with MASLD between 2009 and 2019.
- Classification of patients into metabolic dysfunction-associated steatohepatitis (MASH) using the NAFLD Activity Score (NAS) and assessment of fibrosis via liver biopsy.
- Calculation of Social Deprivation Index (SDI) scores based on patient residential addresses.
Main Results:
- The cohort consisted mainly of Hispanic males with obesity, median age 12 years.
- Higher Social Deprivation Index (SDI) scores correlated with significantly elevated AST levels, higher NAS scores, and increased rates of bridging fibrosis.
- Patients with MASH or fibrosis exhibited significantly higher ALT levels compared to those without.
Conclusions:
- In a cohort of predominantly Hispanic children with MASLD facing socioeconomic disadvantage, higher SDI scores are associated with increased disease severity.
- Findings suggest that socioeconomic factors play a significant role in the progression of pediatric MASLD, impacting laboratory results and liver histology.
Background:
Whether higher socioeconomic deprivation indices are associated with more severe paediatric metabolic dysfunction-associated steatotic liver disease (MASLD), formerly non-alcoholic fatty liver disease (NAFLD), remains unknown.
Objective:
We aimed to evaluate differences in MASLD characteristics and social deprivation in a cohort of urban children.
Methods:
Retrospective study of 277 paediatric patients ≤ 18 years old evaluated between January 2009 and December 2019 with a suspected diagnosis of MASLD who underwent liver biopsy. Patients were classified as having metabolic dysfunction-associated steatohepatitis (MASH) based on their NAFLD Activity Score (NAS). Fibrosis was determined based on biopsy presence. Social deprivation index (SDI) scores were calculated using patient address.
Results:
Patients were predominantly Hispanic males with obesity and a median age of 12 years. Median SDI score was 85 (65-93). Median ALT was significantly higher in patients with MASH compared with MASLD (136 vs. 92 IU/L, p < 0.001) or with fibrosis compared with no fibrosis (120 vs. 68 IU/L, p < 0.001). High SDI group patients had a significantly higher median AST (60 vs. 47 IU/L, p = 0.022), NAS score (4 vs. 3, p = 0.026) and rates of bridging fibrosis (24% vs. 10%, p = 0.023) compared with the lower SDI group.
Conclusion:
Within a cohort of predominantly Hispanic children with MASLD and high socioeconomic disadvantage, there are significant laboratory and histologic differences in patients with higher SDI scores, suggesting increased MASLD severity.

Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of 70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...
