Can fatty liver disease affect children?

Fatty liver disease affects about 10 percent of all children, and about 40 percent of obese children. Children are considered obese when their body mass index, or BMI, is greater than the 95th percentile. The prevalence of fatty liver varies with age. There's an increased prevalence starting at about age 10. For ages 5 to 9, fatty liver is at 3 percent prevalence, and for ages 10 to 14 the prevalence is 11 percent. This is important because statistics guide healthcare providers on when to start screening children for fatty liver. There is also a gender predominance. Boys are more likely to have fatty liver than girls. Further, Asians and Hispanics have increased rates of fatty liver compared with whites and African Americans. African Americans have one of the lowest prevalence of fatty liver, which is likely due to a protective genetic effect.

About 5 percent of children are estimated to have nonalcoholic fatty liver disease (NAFLD), commonly associated with obesity in children and adults.  Fatty liver is thought to effect up to half of all obese children. Children with fatty liver disease may experience abdominal pain or fatigue.
