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.
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.
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).
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.
代谢功能相关脂肪性肝病(MASLD)是美国儿童中最常见的慢性肝病。研究表明,食物不安全与成年人的 MASLD 有关,但针对儿科 MASLD 的研究较少,特别是在高危人群中。我们评估了 4 岁时家庭食物不安全对拉丁裔儿童 MASLD 的影响。
使用前瞻性队列设计,在妊娠期间招募拉丁裔母亲,并对其子女进行随访,直至儿童早期至中期。我们的主要暴露因素是 4 岁时的家庭食物不安全,使用经过验证的美国家庭食物安全食物模块进行测量。我们的主要结局是 MASLD,定义为丙氨酸转氨酶(ALT)≥年龄/性别第 95 百分位+ALT 测量时体重指数(BMI)≥第 85 百分位(在 5-12 岁之间评估)。我们使用多变量逻辑回归模型来检验家庭食物不安全与儿科 MASLD 之间的独立关联。
在 136 名儿童中,28.7%的儿童在 4 岁时报告家庭食物不安全,27.2%的儿童在儿童早期至中期患有 MASLD。大约 49%的 MASLD 患儿和 21%的无 MASLD 患儿存在食物不安全(p<0.01)。4 岁时暴露于家庭食物不安全与儿童后期 MASLD 的发生风险增加 3.7 倍相关(95%CI:1.5-9.0,p<0.01)。
4 岁时暴露于家庭食物不安全与儿童后期 MASLD 的发生风险增加相关。需要进一步研究以探讨减轻食物不安全对 MASLD 风险的机制和影响。
