Higher BMI in Young Adults May up CVD Risk

The researchers also plan to investigate the relationship between higher BMI and other possible disease mechanisms, such as the abundance and diversity of microbes living in the gut

Being overweight as a young adult may cause higher blood pressure and thicken heart muscle, setting the stage for cardiovascular (CVD) disease in later life, a new study has found.

The findings, published in the journal Circulation, suggests higher body mass index (BMI), among the study participants, resulted in higher systolic and diastolic blood pressure.

The researchers also found being overweight also caused enlargement of the left ventricle — the heart’s main pumping chamber.

“Our results support efforts to reduce body mass index to within a normal, healthy range from a young age to prevent later heart disease,” said lead author Kaitlin H. Wade from the University of Bristol Medical School in Britain.

For the study, the researchers used data on several thousand healthy youth aged between 17 and 21 years who participated in the ongoing Children of the 90s study.

“Thickening of vessel walls is widely considered to be the first sign of atherosclerosis — a disease in which fatty plaques build up within the arteries and lead to heart disease,” Wade said.

“However, our findings suggest that higher BMIs cause changes in the heart structure of the young that may precede changes in blood vessels,” Wade added.

According to the researchers, this is the first study to explore if higher BMI results in adverse effects on the cardiovascular system in young adults.

The researchers also plan to investigate the relationship between higher BMI and other possible disease mechanisms, such as the abundance and diversity of microbes living in the gut. (IANS)

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.
