Excessive television viewing during childhood and adolescence is associated with a variety of ills, including obesity. While concern has been expressed about the long-term educational impact of television viewing, few studies have examined the effect into adulthood.

For every hour of television watched per weeknight, the risk of not getting a college degree increased by 43%. Watching television during childhood and adolescence both had a negative effect on educational attainment at 26 years of age, potentially affecting socioeconomic status and long-term well-being.
