Smoking in pregnancy favors asthma in infants, says study

Smoking in pregnancy favors asthma in infants, says study

Children whose mothers smoked during pregnancy may have more difficulty in controlling asthma than other children with the problem, a new study published in the Journal of Allergy and Clinical Immunology suggests. The discovery aims to motivate pregnant or future mothers to quit smoking as soon as possible to preserve their child's health. The study was led by a researcher from the University of California, California, in the United States. The team followed 2,481 children aged 8 to 17 years with asthma. The results showed that, in addition to the known risks of abortion, low birth weight, congenital defects and complications of pregnancy, smoking during pregnancy prenatal care was associated with worsening of children's asthma symptoms. About 35% of them could not control asthma symptoms well. Tobacco is known worldwide for its harm. More than five thousand substances have been identified in tobacco smoke, among them carcinogenic gases and particles, pesticides used during the planting of the tobacco leaf and which are kept in the drying process for the manufacture of the cigarette, among others.

Smoking during pregnancy increases the chances of heart disease in the baby

Mothers who smoke early in pregnancy are more likely to have babies born with heart defects, according to a study published in the journal Pediatrics. The survey, sponsored by the Centers for Disease Control and Prevention, shows that women who smoked sometime in the month before pregnancy until the end of the first trimester were more likely to give light children with certain congenital heart defects compared to women who did not smoke during the same period. The finding also found that one of the most common birth defects in newborns with heart problems is alteration of the ventricular septum, a gap between the right and left ventricles of the heart. The researchers also found conotrunal defects (insufficient blood flow from the ventricle), obstructive right side (blocking blood flow to the right side of the heart), or left.

Many babies with congenital heart disease die in the first year of life and those who survive often require many surgeries, prolonged hospitalizations and lifelong treatment to treat the deficiencies associated with this birth defect.

According to the cardiologist of the Heart Institute (Incor) of São Paulo, Bruno Caramelli, cases of congenital heart disease are rare. However, since today there is a low mortality rate in the perinatal period and there is more quality in the health of the pregnancies, pictures like this, when they occur, catch many unprepared parents. "Congenital heart disease is serious and is associated with other problems, such as Down's Syndrome, for example," he says. Therefore, according to the doctor, in any situation of a congenital defect, heart disease should also be investigated immediately.

Women who smoke should also know that, in addition to tobacco being a possible cause of heart defects, there are other concerns:

  • - Babies born to mothers who smoked during pregnancy are more likely to have congenital defects, such as cleft lip or cleft palate.


    Lack of cerebral oxygenation in fetuses increases the risk of ADHD

    Lack of cerebral oxygenation in fetuses increases the risk of ADHD

    Pediatrics . The survey looked at data from 82,000 children, all five years of age. The results showed that oxygen deprivation in the brain of a fetus increases the risk of ADHD in childhood on average by 16%. If the problem happens due to a pre-eclampsia scenario, the chances increase to 34%. If the lack of oxygen occurs because of a lung injury that prevents the baby's alveoli from remaining open (respiratory distress syndrome), this chance may be 47% higher.

    Children can also be vegetarian?

    Children can also be vegetarian?

    Vegetarianism often generates mistrust of both the population and health professionals. When it comes to this diet for children, most are skeptical of believing that a meat-free menu contains adequate levels of nutrients. Even those who follow the vegetarian diet for many years when they become parents seek help from a qualified professional so that their children do not develop nutritional deficiencies.
