One in four Hainan teens now battles liver disease linked to obesity

A recent survey has uncovered a worrying rise in metabolic dysfunction-associated steatotic liver disease (MASLD) among adolescents in Hainan Province. Over 25% of young people aged 12 to 18 now show signs of the condition, a figure higher than in many comparable studies elsewhere. Researchers warn that without intervention, the disease could lead to severe liver damage and long-term health complications in adulthood.

The study, led by Zhou, Zhang, Chen, and colleagues, found that MASLD is particularly common in male adolescents. It often appears alongside obesity, excess belly fat, and problems with blood sugar control. Genetic factors, such as variations in the PNPLA3 and TM6SF2 genes, also play a role by affecting fat buildup and inflammation in the liver.

Lifestyle choices worsen the problem. High fructose intake and lack of exercise significantly increase the risk. Meanwhile, lower-income families face a heavier burden of the disease, suggesting socioeconomic status influences prevalence. MASLD develops due to insulin resistance, impaired mitochondrial function, and chronic inflammation. If left untreated, it can progress to advanced liver disease and raise the risk of heart and metabolic disorders later in life. The researchers stress that early detection is critical, calling for routine screening in paediatric care using non-invasive methods like biomarkers and elastography. Public health measures are urgently needed to address the growing epidemic. Proposed solutions include school-based health programmes, better nutrition policies, and initiatives to boost physical activity among young people.

The findings reveal that more than one in four adolescents in Hainan Province now live with MASLD. Without targeted action, the condition could lead to lifelong health issues. Authorities are being urged to implement screening and prevention strategies to curb the rising trend.
