Heat waves pose asthma risk spike for babies
Health Canal: Babies are at an increased risk of having an asthma attack during a heat wave, new research into the effects of weather events on the debilitating respiratory condition has uncovered. It's often thought that it's only in the cooler months that parents of asthmatic children need to be extra vigilant. But this new research has shown that hot weather is just as risky - particularly during a heat wave and especially for the very young.
Prof Shilu Tong, from QUT's School of Public Health and Social Work and the Institute of Health and Biomedical Innovation, said a team of health researchers uncovered the surprise finding in a study of hospital admissions during extreme weather events.
"This study was conducted because little information is available on the quantitative relationship between extreme weather events and asthma," Dr Tong said. "It is vitally important to examine the vulnerability of asthmatic children to climate variability and change. Asthma is one of the most frequent chronic childhood illnesses worldwide, and is one of the most common of the five most frequently reported long-term conditions in Australia for children younger than 15. There's no cure. It is useful to know when attacks are likely to occur, so that health authorities can plan better interventions and treatments. And this is important stuff for parents to know.
"There were more than 13,300 emergency department admissions for childhood asthma during the study period (2003-09 in Brisbane). Both hot and cold temperatures saw spikes in hospital admissions for childhood asthma. But it was with heat waves that the largest increase was recorded."
Male children aged up to four were the most vulnerable during heat waves. Children aged 10 to 14 years were more vulnerable during cold events....
