What are the main factors affecting the health of the child's respiratory system?

new predictive respiratory health tests:

The researchers hope that their results will pave the way not only for new predictive tests for respiratory health, but also help reduce inequalities in health care by developing early interventions aimed at reducing these risk factors.

The study analyzes data from 7,545 participants in Bristol's Children of the 90s study, also known as the Avon Longitudinal Study of Parents and Children or ALSPAC, a world-renowned longitudinal study that follows pregnant women and their children from 1991. The study considered 33 key factors spanning the lifespan from birth to age 24, when lung function is at its peak and is a robust indicator of respiratory health later in life. These 33 factors could impact lung function and included sociodemographic, environmental, lifestyle, and physiological characteristics.

the main factors negatively affecting the lung health of the Child:

“The analysis therefore assessed the underlying relationships between these 33 factors and lung health in adulthood,” says lead author Dr. Osama Mahmoud, professor of data science and statistics in the Department of Mathematical Sciences. from the University of Essex.

Some of the main factors negatively affecting a child's lung health include:
  • in mothers, a higher BMI during pregnancy,
  • in mothers, smoking during pregnancy,
  • in children, low birth weight,
  • higher fat mass in primary school,
  • less lean mass than in primary school,
  • early asthma.

childhood factors:

These data thus reveal that out of 33 key factors, those that weigh most heavily on lung function in young adulthood include weight and certain maternal lifestyle factors during pregnancy and, in children, birth weight. and body composition in elementary school. All are childhood factors.

Early onset asthma also unsurprisingly emerges as a factor affecting lung function later in life, the authors point to the need for more attention to this disease and implementation of primary prevention interventions.
