Chubby bubs may face higher asthma risk

Slower weight gain in young children linked to better overall lung function

Infants who gain weight very quickly in the first three years could be at greater risk of asthma later in life, say Dutch researchers.

Babies who packed on the most kilos each year were most likely to have reduced lung patency at age 10, regardless of their current weight, they found.

But slower weight gain was linked to better overall lung function and reduced risk of asthma, particularly among boys.

“These results suggest that weight gain during the first years of life appears to be important for lung development,” the researchers write in Thorax.

More than 4400 children were recruited for the study, which formed part of the wider Generation R study cohort. 

The researchers charted their weight for three years to work out how much they gained each year.

They also calculated the age they reached their highest BMI between the ages of two
