Mom's sugar consumption during pregnancy is linked to child's allergies, study suggests

The team found no association with eczema or hay fever. This group children had 73% higher risk of allergy diagnosis to 2 or more allergies.

Using the data they gathered from the questionnaires, researchers were able to estimate the mothers' free sugar intake based on their total energy intake and daily nutrient intake.

Other studies have suggested increased intake of fructose by children is linked to asthma, but he understood this was the first suggesting foetal exposure may be a cause.

Lead researcher Professor Seif Shaheen said: "We can not say high sugar intake is definitely causing allergic asthma".

Because of these findings, researchers believe that high sugar intake during pregnancy may affect the child's risks for developing asthma and atopic asthma.

In order to find out the link between mother's sugar consumption and baby's allergies, Bedard and her colleagues analyzed the data of sugar consumption in women during pregnancy, one of the limitations of the study was self-reported data.

Experts at Queen Mary University in London studied nearly 9,000 mothers and babies.




Also known as the "Children of the 90s" study, the investigation has followed the progress of children whose mothers were pregnant in the early 1990s.

At age 7.5, the children were assessed as to which of them had doctor-diagnosed asthma and which among them had experienced conditions such as eczema, wheezing, or hay fever in the last 12 months. The children were tested for asthma and skin tests were used to test them for allergens.

When comparing the 20 percent of mothers with the highest sugar intake versus 20 percent of mothers with the lowest sugar consumptions, it saw an increased risk of allergy in offspring by 38 percent and 101 percent higher risk of allergic asthma.

Given the extremely high consumption of sugar in the West, they would certainly be investigating this hypothesis further "with some urgency", he added.

Although they didn't manage to find a cause and effect relationship, they were able to speculate that it's possible that the high intake of sugar during the pregnancy may increase inflammation in the child's developing lung tissue, leaving them susceptible to allergies.

Most importantly, the offspring's free sugar intake in early childhood was found to have no association with the outcomes seen in the analysis.As the study is observational, it does not prove a causal link between maternal sugar intake and allergies or asthma.A randomised controlled trial would be needed to definitively test causality.
