Pediatric Metabolic Dysfunction-associated Steatotic Liver Disease and Food Insecurity

Official title

Pediatric MASLD and Food Insecurity

Overview

This proposal addresses a critical gap in our understanding of the impact of household food insecurity (FI) on pediatric metabolic dysfunction-associated steatotic liver disease (MASLD) severity. There is evidence that children in families that do not have the ability to provide consistently healthy and high-quality foods, such as fruits and vegetables, have worse diet quality that children in households that are food secure. Additionally, evidence from adult studies link household FI to MASLD and liver fibrosis, and prior research of the PI has shown that exposure to household FI in early childhood was associated with a nearly 4 times increased odds of pediatric MASLD in middle childhood. Possible mechanisms linking household FI to pediatric MASLD include lower intake of fruits and vegetables, higher intake of caloric dense nutrient poor foods (e.g., sugar sweetened beverages), and less diversity of foods. Given consensus recommendations for the management of MASLD focus on lifestyle modification, i.e., diet and exercise to achieve weight loss, this proposal seeks to explore the association of household FI and pediatric MASLD disease severity and whether those effects are mediated by dietary intake. Study participants include children/adolescents with MASLD who are receiving care at UCSF's liver clinic and Weight Management for Teen and Child Health (WATCH) Clinic, a pediatric subspecialty clinic.

Detailed description

Metabolic dysfunction-associated steatotic liver disease (MASLD) is now the most common type of chronic liver disease among children and adolescents in the US, with the highest burden among children from low-income families, those with obesity, and those who are Hispanic. MASLD describes a spectrum of liver injury from simple hepatic steatosis to steatohepatitis, which can progress to liver fibrosis, cirrhosis, hepatocellular carcinoma, and liver failure. MASLD is one of the leading indications for liver transplantation in adults. Emerging evidence in adults links household FI to MASLD, liver fibrosis, and mortality. FI is defined by the US Department of Agriculture (USDA) as a state in which there is "limited or uncertain availability of nutritionally adequate and safe foods or limited or uncertain ability to acquire foods in socially acceptable ways." Adults with MASLD and FI have been shown to have poor diet quality that is significantly associated with fibrosis.

Research has found that household FI is highly prevalent in families with children. Fifteen percent of U.S. households, and 30% of San Francisco households with children are food insecure, which limits the ability of these families to consistently provide healthy, high-quality food. Research has found that children living in food insecure households have worse diet quality with regard to specific food categories compared to those in food secure households. Specifically children in food insecure households consume fewer fruits and vegetables (F\&V), and more SSBs. Children in households with severe FI have worse overall diet quality than those who are food secure.

Researchers, including the PI (see preliminary studies below), have found that exposure to household FI in children/adolescents is associated with pediatric MASLD. Given current consensus recommendations for the management of pediatric MASLD focus on lifestyle interventions, i.e., diet and physical activity), this project will assess the association of household FI and MASLD disease severity and whether these effects are mediated by dietary intake.

Primary outcome measures

• Alanine aminotransferase (ALT) [Time frame: 30 days]
• Gamma-glutamyl transferase (GGT) [Time frame: 30 days]

Secondary outcome measures (2)

• Dietary intake of fruits and vegetables [Time frame: 30 days]
• dietary intake of SSBs [Time frame: 30 days]

Eligibility criteria

Inclusion criteria

• Children and adolescents receiving care in the liver and WATCH clinics.
• Family living in California.
• Parent/guardian speaks Spanish or English.
• Child is between the ages of 6 to <17 years.
