  • Smoking during pregnancy can be very dangerous
  • It can lead to asthma and poor lung function in the baby
  • It also can have serve effects on the health of the mother

Women who smoke while pregnant contribute to the severity of asthma and poor lung function in their children warns a study.

The findings published in the journal CHEST suggest that tobacco smoke exposure during pregnancy is more strongly associated with worse lung function than current, ongoing exposure in school-aged children with asthma.

Smoking during pregnancy can be unhealthy for the child.

“This study implicates maternal smoking in pregnancy as the period of second-hand exposure that is more strongly associated with worse lung function in asthmatic children,” said lead investigator Stacey-Ann Whittaker Brown from Icahn School of Medicine at Mount Sinai, New York.

“Maternal smoking in pregnancy may set children with asthma on a trajectory of poor lung function in later childhood, and other studies suggest this effect may be lifelong,” Whittaker Brown said.

Investigators analysed the relationship between lung function and the type of second-hand smoke exposure in a representative sample of school-aged children aged six to 11 years.

The sample consisted of 2,070 children who participated in the 2007-2012 National Health and Nutrition Examination Survey (NHANES) in the US.

Detailed information about ongoing second-hand smoke exposure as well as parental self-reported exposure prior to birth was obtained.

During the study period, lung function was measured using spirometry, and exposure to smoking was assessed through levels of cotinine in the blood, a marker of the extent of current second-hand smoke exposure. Thus, investigators were able to distinguish clearly between exposure in pregnancy and ongoing second-hand smoke exposure.

Nearly 10 percent of both children with and without asthma in the sample had reduced lung function.

Investigators found that current tobacco smoke exposure was independently associated with airflow obstruction in school-aged children, although the extent of the association was small.

However, prenatal tobacco smoke exposure was associated with a 2.5 times increase in odds of having airflow obstruction in children with asthma, the study said. IANS

Growth Hormone Deficiency May Also Hit Healthy Children

Since he started getting these injections two years ago, Spencer has grown about 15 centimeters.

Most healthy children between the ages of four and 10 grow about five centimeters (two inches) a year. So, one family knew something was wrong when their son fit into the same clothes, season after season. Doctors were able to get him growing once again after testing for a growth hormone.

Eleven year-old Spencer Baehman is passionate about baseball.

“My goal is to play college baseball,” Spencer said.

There was only one problem. Spencer was the shortest player on his team. It didn’t stop him from playing, but the height difference was noticeable. And it made Spencer feel different.

“I want to be as tall as these kids,” Spencer said.

At first, Spencer’s parents thought their son was just small, but gradually, they suspected something was wrong. His mom, Stephanie Baehman, became worried.

“It really set in one year coming out of winter into spring when he got out his cleats for spring baseball and he put them on, and they fit. And they never should have fit. Those were from the spring prior,” Baehman said.

Spencer’s parents set up an appointment with Dr. Bert Bachrach, the chief of pediatric endocrinology at University of Missouri Health Care. Nurses measured Spencer’s height.

After careful testing, Dr. Bachrach determined a growth hormone deficiency was causing Spencer’s growth failure. Hormones are basically chemicals that send messages from one cell to another.

“Growth hormone just doesn’t affect your growth, it affects your muscle mass and fat distribution, so that affects your cholesterol, that affects you overall, it also affects your overall sense of wellbeing,” Bachrach said.

Growth hormone insufficiency is a disorder involving the pituitary gland which is a small, pea-sized gland located at the base of the brain. It’s this gland that produces human growth hormone, among others.

Every day, Spencer’s mother gives him a daily hormone injection. Since he started getting these injections two years ago, Spencer has grown about 15 centimeters (six inches). But just in case he doesn’t grow tall, he has a reminder written in each of his baseball caps.

“It says HDMH, which means height doesn’t measure heart,” Spencer read.

And heart is something Spencer has plenty of. (VOA)
