Growth in the first years affects the health of the airways

The first years of life are a critical time for the appearance of possible respiratory diseases in the health of children and adults. Recently, several studies have observed that a weight gain that is higher than the recommended value during this period may be associated with poorer lung function and an increased risk of developing asthma at school age.

A new study, conducted by the Institute of Global Health of Barcelona (ISGlobal), a center promoted by the Banking Foundation & # 8220; la Caixa & # 8221 ;, and the Erasmus University Medical Center of Rotterdam, aimed to analyze whether growth patterns Children, derived from weight and height, repeatedly measured during the first three years of life, affected the airways at age 10.

More specifically, the growth patterns analyzed were the maximum growth rate in weight and height, which usually occurs at the age of one month, and the moment at which the body mass index reaches its maximum, which usually occurs around nine months of age. The work has been published in the journal Thorax.

The experts followed 4,435 girls and boys from the Study Cohort Dutch Generation R from before birth to 10 years. The weight and length of the participants were repeatedly measured during the first three years of life. At age 10, they underwent spirometry to measure their lung function and their parents completed a questionnaire to find out if they had asthma diagnosed.

Risk factors

The data showed that babies who gained weight faster and had a higher body mass index had lower respiratory function at age 10.

"Specifically, in these cases the function of the airways was proportionally smaller than would correspond to the lung capacity.Although there was no link between weight and height growth and asthma risk, this disproportionate development of lung function could be a risk factor for respiratory diseases, "concludes Maribel Casas, researcher at ISGlobal and the Erasmus University. Medical Center and first author of the publication.

On the other hand, it was also noted that "the later the maximum body mass index was reached, the lung function was better and, in the case of children, the lower risk of asthma," explains Casas.

"The results of this study confirm that the growth of children during the first years of life is important for the development of the lungs", adds the researcher.
