If you are planning to start motherhood, quit smoking, say researchers. Exposing your baby to tobacco smoke during pregnancy or after the birth may cause hearing impairment in them.

According to the researchers, babies who were exposed to smoking during pregnancy had a 68 per cent increased relative risk of developing hearing problems.

“This study clearly shows that preventing exposure to tobacco smoke during pregnancy and postnatally may reduce the risk of hearing problems in children,” said Koji Kawakami from the Kyoto University in Japan.

The study, published in the journal Pediatric and Perinatal Epidemiology, included data from 50,734 children aged 3 years.

Out of the group, 3.8 per cent were exposed to smoking only during pregnancy, 3.9 per cent were exposed only to second-hand smoke at 4 months and 0.9 per cent were exposed to tobacco smoke during pregnancy and at 4 months.

The results showed that the prevalence of hearing impairment among babies aged three who were exposed to smoke was 4.6 per cent while those exposed to only second-hand smoke at 4 months had a 30 per cent increased relative risk.

“The findings remind us of the need to continue strengthening interventions to prevent smoking before and during pregnancy and exposure to second-hand smoke in children,” Kawakami added. (IANS)

Though miscarriage is a traumatic experience for both parents, resulting in feelings of loss and grief that in some cases can lead to anxiety and depression, women experiencing miscarriage should be offered a choice in the treatment they receive, suggests a study.

Miscarriage is the most common complication of pregnancy and affects an estimated one in four pregnancies.

Although guidelines recommend trying to resolve an unsuccessful pregnancy naturally, the new analysis shows that this is only successful in 70 per cent of cases, and potentially comes with complications that are rarely communicated to patients.

Some women are more keen on having a quick surgical intervention so that they can resume their lifestyle immediately, some are very keen to avoid surgery and prefer to go with a tablet, and others want to take a more natural approach,” Wattar added. Pixabay

The study from the University of Warwick and Queen Mary University of London, demonstrates little to no difference in medical effectiveness in resolving an unsuccessful pregnancy between medical and surgical options.

Thus, the team recommend the doctors to offer women a choice of treatment options for miscarriage to enable them to make an informed decision that takes account of potential uncomfortable side effects, long waiting times and extended periods of recovery.

“What we have to do is provide women with evidence about the benefits and effectiveness of each treatment option and potential side effects so that they can choose what they feel most comfortable with,” said lead author Bassel Wattar from Warwick Medical School.

“Some women are more keen on having a quick surgical intervention so that they can resume their lifestyle immediately, some are very keen to avoid surgery and prefer to go with a tablet, and others want to take a more natural approach,” Wattar added.

For the results, published in the journal Human Reproduction Update, the team reviewed 46 trials involving over 9,000 women who experienced spontaneous loss of pregnancy (miscarriage) before 14 weeks gestation.

During a miscarriage, the body will aim to resolve the unsuccessful pregnancy naturally but conservative treatment can be painful with increased bleeding, increased likelihood of hospital admission, reduced quality of treatment and reduced satisfaction.

However, surgery which include electric vacuum aspiration, and medical treatment with a tablet were found to have similar effectiveness in treating miscarriage as conservative treatment. (IANS)
