4. "There are no absolute standards for body fat percentages needed by men and women."
5. "Persons having body fat percentages greater than 20% are at an increased risk for illness."
Correct Answer: 1, 2, 5
During the teen years differing percentages of body fat are needed by girls and boys; with females requiring a higher percentage of body fat. A range of 12% to 20% body fat in men and 20% to 30% in women has been suggested for health. The absolute minimum levels of body fat are still being studied; however, experts do believe that there are minimum body fat percentages. Research aimed at development of future standards and references for body fat percentage will address the relationship between BMI and body fat percentage and allow the nurse a clearer assessment of body composition traits associated with health risks. Age-specific recommendations are also needed. Standards of body fat percentage that are associated with health or morbidity and mortality have not been established. Many sources agree that a minimum essential body fat percentage exists.
