Food insecurity is a risk factor for metabolic dysfunction-associated steatotic liver disease in Latinx children

Introduction

Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common chronic liver disease among US children. Studies have associated food insecurity with MASLD in adults, but there are few studies of pediatric MASLD, particularly in high-risk populations. We assessed the impact of household food insecurity at 4 years of age on MASLD in Latinx children.

Methods

Using a prospective cohort design, Latina mothers were recruited during pregnancy and followed with their children until early to mid-childhood. Our primary exposure was household food insecurity at 4 years of age measured using the validated US Household Food Security Food Module. Our primary outcome, MASLD, was defined as alanine transaminase (ALT) ≥95th% for age/gender plus body mass index (BMI) ≥85% at time of ALT measurement (assessed between ages 5–12). We used multivariable logistic regression models to test for independent associations between household food insecurity and pediatric MASLD.

Results

Among 136 children, 28.7% reported household food insecurity at 4 years of age and 27.2% had MASLD in early to middle childhood. Approximately 49% of children with MASLD and 21% of children without MASLD were food insecure (p < 0.01). Exposure to household food insecurity at age 4 was independently associated with a 3.7-fold higher odds of MASLD later in childhood (95% CI: 1.5–9.0, p < 0.01).

Conclusions

Exposure to household food insecurity at 4 years of age was associated with increased risk for MASLD later in childhood. Further studies are needed to explore mechanism(s) and impact of reducing food insecurity on risk for MASLD.
