A study published in the journal Environmental Health Perspectives has revealed that children who are exposed to cigarette smoke prenatally and during the first year of their life are likely to develop behavioral problems by the time they are of school age. Particularly problematic during the gestational years, tobacco smoke can more than double the risk of childhood behavior problems.
Scientists from Germany analyzed children whose mothers smoked while they were in the womb as well as children who were exposed to second hand smoke following their birth up until their first birthday. The children who were only exposed prenatally were 90 percent more likely to develop behavioral problems compared to children whose mothers did not smoke at all. Children who were exposed only after birth had a 30-percent higher risk. Children exposed both prenatally and after birth had a double risk of developing abnormal behavior problems.
In order to isolate the true cause of behavioral problems, scientists crafted a detailed questionnaire that aimed to eliminate possible biases that would have altered results, such as external social and environmental factors. When all was said and done, hyperactivity, attention deficit disorder, and social interaction problems were among the primary setbacks observed in the tobacco-exposed children.
Because the negative effects of tobacco smoke were found to be the greatest during fetal development, scientists see an undeniable link between tobacco and developmental problems. The formative years of a child's growth and maturation are severely upset by the presence of tobacco, something sc
