Smoking during pregnancy linked to asthma severity in kids

Prenatal tobacco smoke exposure was associated with a 2.5 times increase in odds of having airflow obstruction in children with asthma

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

Workout Before Breakfast To Get Fit, Says Study

The research team also wanted to focus on the impact on the fat stores in muscles for individuals who either worked out before or after eating

 Fitness enthusiasts, take a note! Researchers have found that a nice Workout before breakfast could increase health benefits of exercise.

The study, published in the Journal of Clinical Endocrinology and Metabolism, the Universities of Bath and Birmingham found that by changing the timing of when you eat and exercise, one can better control the blood sugar levels.

“We found that the men in the study who exercised before breakfast burned double the amount of fat than the group who exercised after,” said study author Javier Gonzalez from the University of Bath.

“Our results suggest that changing the timing of when you eat in relation to when you exercise can bring about profound and positive changes to your overall health,” Gonzalez said.

The six-week study, which involved 30 men classified as obese or overweight and compared results from two intervention groups (who ate breakfast before/after exercise) and a control group (who made no lifestyle changes), found that people who performed exercise before breakfast burned double the amount of fat than the group who exercised after breakfast.

They found that increased fat use is mainly due to lower insulin levels during exercise when people have fasted overnight, which means that they can use more of the fat from their fat tissue and the fat within their muscles as a fuel.

While this did not lead to any differences for weight loss over six weeks, it did have ‘profound and positive’ effects on their health because their bodies were better able to respond to insulin, keeping blood sugar levels under control and potentially lowering the risk of diabetes and heart disease.

The research team also wanted to focus on the impact on the fat stores in muscles for individuals who either worked out before or after eating and the effect this had on insulin response to feeding.

Over the six-week trial, the research team found that the muscles from the group who exercised before breakfast were more responsive to insulin compared to the group who exercised after breakfast, in spite of identical training sessions and matched food intake.

The muscles from those who exercised before breakfast also showed greater increases in key proteins, specifically those involved in transporting glucose from the bloodstream to the muscles.
