Research shows that overweight mothers are more likely to have children with asthma


One study found that women who were overweight before becoming pregnant were more likely to have children with asthma.

Japanese researchers found that mothers who were obese before conception were 28% more likely to have a child diagnosed with asthma before the age of 3.

Overweight women are also 17% more likely to have a baby with asthma than women of a healthy weight.

Some experts suggest this may be because overweight women produce more of a hormone called leptin, which can make the fetal airways more sensitive.

Co-author, Dr Emiko Noguchi, from the University of Tsukuba, said: ‘[These findings] problem because asthma is often a lifelong condition that can disrupt daily life. ‘

Japanese researchers have found that women who were overweight before becoming pregnant are more likely to have children with asthma.

Asthma is the most common long-term condition in children in the UK, affecting around one in 11 young people.

The study, which involved more than 67,000 women, was published in the Journal of Allergy and Clinical Immunology.

The women’s pre-pregnancy weight was obtained from their medical records or questionnaires.

While three-quarters have a normal body mass index (BMI), about 7% were overweight before conception and nearly 2% were obese.

Among children, 11% developed asthma before the age of three.

The risk of asthma in the children of obese mothers was higher than that of mothers of a healthy weight, even when other important factors were taken into account.

These factors include whether the mother has asthma, which is more likely to be passed on to their children, plus whether smoking during pregnancy makes children more susceptible to asthma. no and the sex of their children, as asthma is more common in boys during childhood. .

However, the authors point out that the study was conducted in Japan, where being overweight is much less common than in the UK.

The researchers also found childhood allergies to cow’s milk and eggs were less common in toddlers and babies born to overweight mothers, with the cause of this unclear.

The study found no link between mothers’ weight and eczema in young children when the researchers also looked at the issue.

But the analysis, performed among women recruited for a nationwide Japanese study between 2011 and 2014, demonstrates earlier evidence that asthma is more common in children born to overweight mothers.

Research from 2011 suggests that obese pregnant women may put their children at a higher risk of developing asthma.

The study that included nearly 130,000 Swedish mothers found that children of very obese women had a 57 percent higher risk of developing asthma than children of mothers of healthy weight.

Even children of slightly overweight mothers, with a BMI between 25 and 30, have a slightly increased risk of asthma.

Regarding the new finding, Dr Noguchi said: ‘Women should be careful about their weight before becoming pregnant to reduce their risk of many diseases and possibly also reduce the risk of their child developing asthma.’
