A meta-analysis published in The BMJ suggests that infants exposed to selective serotonin reuptake inhibitors (SSRIs) during late pregnancy are at a higher risk for persistent pulmonary hypertension, which can lead to breathing difficulties. However, the authors stress that the overall risk remains low and that depression during pregna...
A new study by Wellesley College economists finds that MTV's '16 and Pregnant' and 'Teen Mom' led to a 5.7 percent reduction in teen births, accounting for one-third of the overall decline. The shows may have conveyed information to teens who were at risk of childbearing, preventing them from giving birth at a young age.
Prenatal retinoid deficiency linked to airway hyperresponsiveness in adult mice, affecting proper airway development and inflammatory responses. Retinoid signaling plays crucial role in preventing inappropriate pulmonary inflammation.
A new longitudinal study suggests that prenatal exposure to maternal stress hormones and smoking during pregnancy increase the risk of nicotine dependence in daughters, but not sons. The study found that elevated cortisol levels and maternal smoking were associated with increased rates of nicotine dependence in female offspring.
A new study finds that heavy viewers of 'Teen Mom' and '16 and Pregnant' have unrealistic perceptions of teen mothers' quality of life, income, and involved fathers. The research, led by Indiana University professors, suggests that these shows lead to a distorted view of reality TV and teen parenthood.
