The assessment of the relationships between body image, dietary intake, iron status, percent body fat and menstrual status of female competitive iceskaters, ages 11-16

Competitive ice skating is a sport in which thinness is stressed and is expected of these athletes. This obsession with thinness leads to decreases in body weight, psychological effects, and eating disorders. This study sought to investigate whether there was a relationship between body image, dietary intake, iron status, percent body fat, and menstrual dysfunction in 11 to 16 year old female ice skating competitors in the United States. Little research has been conducted with ice skaters in the area of body image. However, ice skaters, ballet dancers, and many other athletic groups are involved in an area of our culture in which a lean body image is encouraged.The experimentally accessible population for this study included those U.S. competitive ice skaters attending the Sports Medicine and Science Testing Program at the Indiana World Skating Academy. The target population included females ages 11 to 16.Statistical analysis of the data revealed:(1) A significant relationship between thiamin, calcium, and riboflavin intake and eating attitude test score (body image) in female ice skaters, ages 11-16.(2) A significant relationship between menstrual dysfunction and the weights of female ice skaters, ages 11 to 16.When dietary records were evaluated, the mean caloric intake of the skaters was low at 1781 calories. Caloric intakes were 445 calories less than estimated necessary to support normal growth (Benson et al, 1985). None of the vitamin levels fell below 96% of the Recommended Dietary Allowances (RDA), however, minerals which were less than 75% of the RDA included calcium, iron, magnesium, zinc and potassium. There were more than 14 participants who consumed greater than 100% of the RDA for vitamin C, vitamin E, folacin, vitamin B-12, niacin, riboflavin and thiamin.Of the 19 participants who participated in hematological assessment, four were found to have an impaired iron status. The contributor to this low iron state may have been poor dietary iron consumption, as 10 of the 20 skaters consumed less than 67% of the RDA for iron.The participants' body image, measured by the Eating Attitude Test (EAT), revealed that two participants had scores greater than 30, indicative of eating disorders.The participant's age may have played a role in the tendency towards an eating disorder, for when age was correlated with EAT scores, a positive relationship existed, indicating that as age increased, the tendency towards an eating disorder increased.Training has posed enormous changes on the body composition of these female ice skaters. Ranges of 21.5% to 25.4% body fat are expected for the age group of 11 to 16. However, 71% of the ice skaters had a body fat less than 22%, and 38% of the skaters had a body fat less than 17%.This study identified numerous menstrual dysfunctions in among the participants as 9 of the 21 participants had irregular menses, and 4 have never menstruated and their ages were 15, 14, 13 and 11. The weights of these ice skaters may have a role in the menstrual dysfunctions, as a significant relationship was found between menstrual dysfunctions and the weights of these skaters. Those participants who had never menstruated, had four of the five lowest weights at 72 lbs, 90 lbs, 95 lbs, and 103 lbs. Those participants who had irregular menses, had weights below 117 lbs.The data indicated the main concerns about the diets of subjects in this study were the low caloric, calcium, and iron intakes. Ice skaters need to be aware of the benefits of a "normal caloric" intake, which can provide adequate amounts of calcium and iron in the diet. In addition, an adequate caloric intake could increase body weights of the ice skaters, and help alleviate amenorrhea and associated health complications.Department of Home EconomicsThesis (M.S.
