Exposure of babies to environmental ozone is associated with asthma between the ages of four and six

Exposure to mild ozone air pollution during the first two years of life is linked to the development of asthma and wheezing in children between the ages of four and six, both individually and in combination with nitrogen dioxide and fine particles. This relationship was not found in children under eight or nine years old, according to a study published in JAMA Network Open. The epidemiological study is based on data from more than 1,000 children in the U.S.

Global child immunisation levels stagnate in 2023, according to WHO and UNICEF data

Global childhood immunisation coverage stagnated in 2023, with 2.7 million more children unvaccinated or under-vaccinated than at pre-pandemic levels in 2019. This is one of the data published by the World Health Organization (WHO) and UNICEF in the World Health Organization's Worldwide Estimates of National Immunisation Coverage (WUENIC), which captures global vaccination trends against 14 diseases. More than half of unvaccinated children live in 31 countries with fragile and conflict-affected environments.

Sex and gender are associated with distinct brain network patterns

Both sex and gender are associated with distinct networks in the brains of boys and girls, according to an analysis of brain images of 4,757 children in the US. Understanding these neurobiological patterns is important for identifying how sex and gender influence health and for developing specific diagnostic tools, the research team writes in Science Advances.

Reaction: Adolescents and children from low socioeconomic neighborhoods walk less and engage in less physical activity

A study published in the journal PLOS ONE, which includes data from over 3,000 Spanish adolescents and children, has shown that those living in more walkable areas report spending more minutes per day engaging in active transportation compared to those from less walkable neighborhoods. Along those lines, the lowest average minutes spent playing outdoors are observed among participants from neighborhoods with lower socioeconomic status and less walkability. The research is part of the PASOS study, coordinated by the Gasol Foundation.

Neighbourhoods with no space to play, walk or play sport: how the postcode affects children and young people's health

Research involving more than 3,000 adolescents and children from all Spanish autonomous communities concludes that those living in less walkable neighbourhoods with lower socioeconomic status walk less and engage in less physical activity at weekends than those living in more walkable areas with higher socioeconomic status. The paper, published in the journal PLOS ONE and part of the PASOS study, was presented by two of its authors at a briefing organised by SMC Spain.
