This research suggests a potential link between fish consumption and reduced asthma severity.
A study of nearly 500,000 women found that taking paracetamol or other painkillers during pregnancy increases the risk of asthma in children, but the risk is similar when other types of painkillers are used. The research suggests that another factor linked to painkiller use and asthma risk may be chronic pain and stress.
A randomized clinical trial found no association between high-dose vitamin D supplementation during pregnancy and the risk of asthma in children at age 6. The study followed 545 children whose mothers received either high-dose or standard-dose vitamin D supplementation.
A new study found that urban children with poorly controlled asthma experience higher school absences and lower academic performance. Ethnic minority children, particularly Latino kids, face greater disparities in academic outcomes due to unique stressors related to their background and migration experiences.
