Exposure to Pollen During Pregnancy May up The Risk of Asthma in Kids

For the study, the team analysed cord blood collected from hundreds of babies born in Melbourne, Denmark and Germany

Babies born to mothers who got exposed to pollen during the last trimester may be at increased risk of developing respiratory diseases such as asthma, says a study.

The findings showed that those born during the peak grass pollen season had high immunoglobulin E (IgE) levels in umbilical cord blood — a marker used to predict the development of allergic diseases.

“We know that outdoor pollen exposure during the first couple of months after birth can lead to allergic respiratory diseases and we suspected that exposure during the later stages of pregnancy may also be important,” said lead researcher Bircan Erbas, Associate Professor from La Trobe University in Melbourne, Australia.

“Many studies have shown that babies with high levels of IgE in cord blood can go on to develop allergies later in childhood, but little is known about how these levels are affected by exposure to pollen in utero.”

However, the study published in Environment International, also showed that being pregnant for an entire grass pollen season may have a protective effect on babies.

“We found these babies had lower IgE levels. This was a significant finding and indicates the possible development of a sensitisation barrier,” Erbas said.

Erbas stressed that the study did not suggest that all babies born during high pollen seasons would develop respiratory disease or other allergies.

“The study provides new insight that could help us predict and manage diseases like asthma – which are a significant public health burden.

“However, it’s important to remember there are a number of factors that can determine who gets asthma or allergies. This is one piece of the puzzle,” she explained

Exposure to Certain Disinfectants Can Cause Obesity in Kids: Research

Early life exposure to certain disinfectants used at home could be making children overweight by altering the composition of their gut bacteria, suggests new research.

Babies living in households that used eco-friendly cleaners had different microbiota and were less likely to be overweight as toddlers, showed the findings published in CMAJ (Canadian Medical Association Journal).

For the study, the researchers analysed the gut flora of 757 infants from the general population at age 3-4 months and weight at ages 1 and 3 years, looking at exposure to disinfectants, detergents and eco-friendly products used in the home.

The researchers looked at data from the Canadian Healthy Infant Longitudinal Development (CHILD) birth cohort on microbes in infant fecal matter. They used World Health Organization growth charts for body mass index (BMI) scores.

Associations with altered gut flora in babies 3-4 months old were strongest for frequent use of household disinfectants such as multi-surface cleaners, which showed lower levels of Haemophilus and Clostridium bacteria but higher levels of Lachnospiraceae.

The researchers also observed an increase in Lachnospiraceae bacteria with more frequent cleaning with disinfectants.

They, however, did not find the same association with detergents or eco-friendly cleaners.

“We found that infants living in households with disinfectants being used at least weekly were twice as likely to have higher levels of the gut microbes Lachnospiraceae at age 3-4 months,” said Anita Kozyrskyj, Professor at the University of Alberta in Canada.

“When they were 3 years old, their body mass index was higher than children not exposed to heavy home use of disinfectants as an infant,” Kozyrskyj said.

“Those infants growing up in households with heavy use of eco cleaners had much lower levels of the gut microbes Enterobacteriaceae,” she said.
