Disordered Eating and The Female Athlete Triad Flashcards
Female Athlete Triad
interrelationships among energy availability, menstrual function, and bone mineral density
What does disruption of LH and FSH do?
shuts down stimulation to the ovary, ceasing control of estradiol
low estradiol creates a hormonal environment that mimics menopause
spectrum of energy availability
- clinical eating disorders
- subclinical eating disorders
- low energy availability
- adequate energy availability
- excessing energy availability
Primary amenorrhea
-absence of menstruation by age 16 in a girl with secondary sex characteristics
Secondary amenorrhea
-absence of 3 or more consecutive menstrual cycles in a girl who has begun menstruating
Functional hypothalamic amenorrhea
- low body fat levels and exercise related chemicals disrupt the interplay of sex hormones estrogen and progesterone
- directly attributable to a low energy availability
Spectrum of bone health
- low bone mass
- stress fractures
- osteoporosis
How is bone strength characterized
by bone mineral content and the quality of the bone
bone quality
the process of bone turnover
most accepted diagnostic tool?
DEXA
Osteoporosis
chronic condition characterized by low bone mass and microarchitectural deterioration of bone tissues leading to enhanced skeletal fragility and increased risk of fracture
Principle cause of premenopausal osteoporosis in active women
decreased ovarian hormone production and hypestrogenemia
Sports that are at risk for the female athlete triad
-figure skating, dance, distance running, diving, swimming, body building, track, cheerleading, wrestling, gymnastics
Spectrum of eating disorders
- normal eating patterns
- disordered eating
- eating disorders
Who establishes fixed criteria that individuals must meet in order to be diagnosed with an eating disorder?
DSM-IV
