Heavy fish intake during pregnancy 'increases childhood obesity risk'

16 February 2016

Women who consume a lot of fish during pregnancy could be increasing the risk of their children becoming obese.

This is according to a new study from the University of Crete in Greece, which analysed data from 26,184 pregnant women and children to examine associations between maternal fish intake and childhood growth and obesity.

Women who ate fish more than three times per week when they were pregnant generally gave birth to children with higher BMI values at two, four and six years of age compared with women who ate fish less.

High maternal fish intake during pregnancy also was associated with an increased likelihood of rapid growth, with the magnitude of these effects shown to be greater in girls than boys.

The researchers stated: "Contamination by environmental pollutants in fish could provide an explanation for the observed association between high fish intake in pregnancy and increased childhood adiposity."

However, they noted that a lack of information on organic pollutant levels among study participants means this hypothesis remains unproven.
