Nutrition
As television takes time away from play and exercise activities, children who watch a lot of television are less physically fit and more likely to eat high fat and high energy snack foods.
Television viewing makes a substantial contribution to obesity because prime time commercials promote unhealthy dietary practices. Television can also contribute to eating disorders in teenage girls, who may emulate the thin role models seen on television. Eating meals while watching television should be discouraged because it may lead to less meaningful communication and, arguably, poorer eating habits.
Advertising
Advertising can have positive effects on children’s behaviour. Although some health care professionals disagree about the health benefits of appropriate milk use, milk consumption has increased as a result of print and broadcast advertisements.
The developmental stage of a child plays a role in the effect of commercials. Young children do not understand the concept of a sales pitch. They tend to believe what they are told and may even assume that they are deprived if they do not have advertised products. Most preschool children do not understand the difference between a program designed to entertain and a commercial designed to sell. A number of studies have documented that children under the age of eight years are developmentally unable to understand the difference between advertising and regular programming.
The average child sees more than 20,000 commercials each year. More than 60% of commercials promote sugared cereals, candy, fatty foods and toys. Cartoon programs based on toy products are especially attractive. The question of whether children are more resilient to the influence of television is debated frequently. Most studies show that the more time children spend watching television, the more they are influenced by it. Earlier studies have shown that boys may be more susceptible than girls to television violence.
