Successful programs involve repeated practice and ramping up challenges to executive control, such as computerized training and aerobic physical activity.
A study by Columbia University's Mailman School of Public Health found that female students, racial/ethnic minorities, and students of lower socioeconomic status are particularly affected by inadequate sleep. The proportion of adolescents who regularly get seven hours of sleep decreased among all groups between 1991 and 2012.

The researchers also discovered that these symptoms are strongly linked to self-destructive thought processes, which can increase the risk of suicide.
A new study finds that colorectal cancer incidence is increasing among young adults aged 20-39 years in the US.

The research suggests maintaining those discussions as children grow older can help prevent underage drinking. The study found a correlation...
A new study reveals that adolescents have dramatic misperceptions about their peers' behaviors, leading to conformity to social norms. Teens overestimate the amount of drug- and alcohol-use and sexual behaviors among their peers, while underestimating the time spent on studying or exercise.

A study by the University of Hawaii Cancer Center found nearly 30% of Hawaiian teens had tried e-cigarettes, with 17% using them only. The rate is three times higher than previously reported US studies. E-cigarette manufacturers' aggressive marketing and wide availability may contribute to this trend.
