Effects of advertising on teen body image
The effects of advertising on teen body image have been studied by researchers, ranging from psychologists to marketing professionals. While many factors, such as "parenting, education, [and] intimate relationships" also affect body image, "the media and body image are closely related." This is because thousands of advertisements contain messages about physical attractiveness and beauty, examples of which include commercials for clothes, cosmetics, weight reduction, and physical fitness.
