Women, now you have another reason to breastfeed your newborn. According to a new study, babies who are breastfed for at least the first six months of their life have low chances of developing liver disease during adolescence.

The findings showed that pre-pregnancy BMI within the normal range was shown to decrease risk of adolescent non-alcoholic fatty liver disease (NAFLD) by half.

Also, a minimum of six months of exclusive breastfeeding can further cut down the risk by a third.

“We wanted to see if there was any association between adolescent non-alcoholic fatty liver disease, maternal factors and infant nutrition,” said lead researcher Oyekoya Ayonrinde, clinical senior lecturer at University of Western Australia.

In the long-term, NAFLD can lead to scarring (fibrosis) of the liver and a potentially life-threatening condition called cirrhosis in some individuals. “Our results demonstrate the grave impact maternal factors can have on the risk of developing liver disease in adolescence,” Ayonrinde added.

Recent studies suggest that it has become the most common liver disease in people aged two to 19-year-old, with half of obese children suffering from the condition. Excessive childhood weight gain is believed to be a key contributor to this rise.

The study demonstrates the importance of proper infant nutrition and the benefit of exclusive and extended breastfeeding for six months, the researchers suggested.

The team collected data such as maternal pregnancy, birth, childhood and adolescent characteristics through questionnaires, direct interviews, physical examinations and blood tests.

The team conducted liver ultrasounds in 1,170 17-year-olds to diagnose NAFLD. The results revealed that over 15% of teenagers, out of the study cohort, were diagnosed as having NAFLD.

Individuals who were exclusively breastfed as infants for six or more months, showed lower prevalence of adolescent NAFLD when compared to those who were breastfed for less than six months.

The findings were presented at The International Liver Congress 2016 in Barcelona, Spain.
