Eating disorders threaten the physical and mental health of an alarming number of people today. Eating disorders are serious and can be life threatening, therefore it is imperative that researchers investigate factors that may contribute to body image dissatisfaction and eating disordered behavior. The goals of this study were to determine whether there are significant differences in the level of eating disorders and body dissatisfaction between different age groups and whether different age groups have different factors contributing to disordered eating and body dissatisfaction. Results indicate that older groups are just as vulnerable to disordered eating and body dissatisfaction as are younger groups. In addition, different factors, including mass media, self-esteem, perfectionism, negative affect, anxiety, and self-focus, relate to disordered eating and body dissatisfaction in different age groups.
