According to new data from the Substance Abuse and Mental Health Services Administration (SAMHSA), more teen pregnancies took place from 2005 to 2006 for the first time in more than a decade. Statistically, teenagers who become pregnant have also demonstrated the likelihood to engage in other risky behavior, such as substance abuse. Following SAMHSA’s Treatment Episode Data Set (TEDS) report, pregnant teenage admissions to substance abuse treatment facilities increased from 1,300 admissions in 1992 to 1,700 admissions in 2007. Since 1992, marijuana abuse among pregnant teenagers more than doubled in 2007, and methamphetamine abuse more than quadrupled.
While it’s well known that secondhand smoke can be dangerous for children, a new study confirms that it’s also dangerous for newborns of mothers who are exposed to secondhand smoke during pregnancy.
Prenatal alcohol exposure is widely known to impair brain development in exposed offspring. Rodent studies have shown that developmental deficits in newborns related to altered levels of a brain chemical called serotonin (5-HT), leading to subsequent alterations in patterns of neonatal acute pain responses and/or hypothalamic-pituitary-adrenal (HPA) stress reactivity.
