Researchers Lorette I. Winters and Paul C. Winters found that while black teens are twice as likely to be pregnant, rates for minor whites have increased and surpassed those of poor black minors. In better economies, the difference between black and white teen pregnancies nearly disappears.
Researchers found that parents tend to blame their children more when they are sexually abused by an adolescent, rather than an adult. This bias may be due to cultural and societal expectations surrounding adolescent sex offenders, leading parents to doubt their child's ability to prevent the abuse.
Researchers analyzed data from an observational study to examine the relationship between HIV illness severity and psychiatric disorders. The study found limited evidence of associations between specific antiretroviral therapy and psychiatric symptoms, but noted associations with quality of life and cognitive functioning.
A widely used behavioral prevention model in schools appears to reduce bullying and peer rejection. The School-wide Positive Behavioral Interventions and Supports (SWPBIS) model promotes positive changes in staff and student behaviors, reducing the likelihood of engaging in bullying behavior.
Young people worldwide are at risk of depression, which can lead to serious health problems if left untreated. Research suggests that prevention strategies targeted at high-risk individuals, such as cognitive behavioural therapy and interpersonal therapy, have shown promise in reducing depressive symptoms.
Research finds that financially impoverished schools significantly predict adolescent weight problems, regardless of parental education level. Well-educated parents can mitigate this effect by recognizing health issues and teaching healthy food choices.
