Section 5: Weight and Dietary Behaviors


Background

National data show that obesity is increasing among adolescents. Obesity acquired during childhood often persists into adulthood, increasing the later risk for diabetes, high blood pressure and heart disease8. In addition, obesity can cause social and psychological stress to children and adolescents9.

Adolescent girls may develop eating disorders. An overemphasis on thinness may also be unhealthy.

To avoid problems of obesity and eating disorders, healthy eating habits should be encouraged among adolescents. Current dietary guidelines include increasing consumption of breads, grains and cereals; eating at least five servings of fruits and vegetables per day and maintaining a healthy weight10.


Description of Weight

About one-third of middle school girls describe themselves as overweight. Girls are slightly more likely than boys to describe themselves as overweight and boys are more likely to describe themselves as underweight or of normal weight.

Trying to Lose Weight

Although 34.0% of girls describe themselves as overweight, 57.8% are trying to lose weight. The difference between perception of being overweight (22.5%) and trying to lose weight (31.4%) is not as dramatic among the boys.
