New Study Reveals Alarming Rise of Fatty Liver Disease in Young Adults

A recent study has uncovered a concerning trend: one in five young adults now shows evidence of fatty liver disease, a condition traditionally associated with older adults in their 40s to 60s. The findings, published by the Children of the 90s project, a long-term study following thousands of children born between 1991 and 1992, highlight the growing prevalence of this silent epidemic among younger populations.

The study found that at age 24, 20% of participants had evidence of fatty liver disease, with 2.5% exhibiting more advanced liver scarring or fibrosis. Researchers also discovered that high BMI in adolescence is the strongest predictor of developing liver scarring in young adulthood. Alcohol consumption and obesity were identified as the primary causes of fatty liver disease, with the combination of these factors leading to more severe liver damage.

The rise of fatty liver disease in young adults is a public health concern with potential long-term consequences. Early detection and intervention are essential to prevent the progression of the disease and its associated complications, such as liver cirrhosis, liver cancer, and cardiovascular events.

Non-alcoholic fatty liver disease (NAFLD), also known as metabolic dysfunction-associated steatotic liver disease (MASLD), affects more than one in four American adults, according to the American Heart Association. The primary cause is weight gain along with metabolic risk factors such as type 2 diabetes, high blood pressure, high triglycerides, and obstructive sleep apnea. Lack of high-quality sleep has also been linked to the development of NAFLD.

Experts stress the importance of screening for fatty liver disease in patients with risk factors, even in the absence of symptoms. NAFLD is a preventable and reversible condition, especially in its early stages. Diagnosis can be made through blood tests, imaging tests, and newer tests that measure the amount of fat in the liver.

The Children of the 90s study is currently assessing participants at age 30 to understand the trajectory of liver disease and identify targets for public health interventions. The study's latest 30 Clinic has had over 7,500 participants, and researchers hope to have 2,000 more before it concludes this summer. The findings from this long-term study have informed policy and childcare advice worldwide.

In the Children of the 90s study, researchers continue to shed light on the growing problem of fatty liver disease in young adults, emphasizing the need for targeted measures to reduce alcohol and obesity-related harm. Dr. Kushala Abeysekera, the study's lead author, stated, "We need to ensure that there are strategies in place to screen and identify individuals who are at risk, and to provide advice, education, and interventions to prevent progression to more advanced disease."
