Smoking is something that women need to avoid during pregnancy. In addition to endangering the health of pregnant women, smoking will also interfere with the health of the fetus.
Not only cigarettes are harmful to health during pregnancy, pregnant women who do not smoke, but are exposed to secondhand smoke (passive smoking) also have various health risks that will be experienced.
Recently, there have been studies showing that pregnant women who are exposed to secondhand smoke will increase the risk of respiratory problems in their children after birth.
Reporting from various sources, the following Popmama.com has summarized a new study which states that exposure to cigarette smoke during pregnancy can increase the risk of breathing in children.
1 Findings are based on cotinine levels during pregnancy
Reporting from Medicinenet, the research compiled by scientists from Harvard Medical School is based on blood levels of cotinins during pregnancy and childhood.
Keep in mind, blood cotinins are the result of nicotine that is processed by the body. So scientists will link cotinine levels and reduced lung function at age 6.
The findings are scheduled to be presented by scientists at an online meeting of the American Thoracic Society.
2 Minor exposures also have an effect on the lung function of the child
In the research conducted, it was noted that there was a decrease in lung function in children who were exposed to large amounts of cigarette smoke, as well as low amounts of cigarette smoke.
"Most of the exposure, especially during pregnancy is direct exposure," said lead author Dr. Hanna Knihtilä from Harvard Medical School and Brigham and Women's Hospital in Boston.
In his explanation, it was stated that even a small amount of exposure would pose a risk to the health of the child when he was older, which would damage the child's lung function.
3 There is an increase in cotinine levels during pregnancy
The new study, conducted by Harvard Medical School scientists, is a study involving 476 couples of mothers and their children.
In this study, the blood cotinine levels of the mother and child samples were measured twice, namely during pregnancy and when their children were 1, 3, and 6 years old.
From the provisional results, the researchers estimated cigarette smoke exposure and lung function in children as measured at 6 years of age. Some pregnant women who smoke and secondhand smoke are known to experience increased levels of cotinins during pregnancy and in their children.
The existence of new studies related to the impact of exposure to cigarette smoke during pregnancy on the respiratory health of children is expected to make all mothers more alert and avoid cigarette smoke for health during pregnancy, as well as the health of children in the future.
