In 1992, the American College of Sports Medicine first recognized that
girls and women in sports were particularly susceptible to three
interrelated conditions – disordered eating, menstrual irregularity,
and osteoporosis – that have come to be known as the "female athlete
triad."
1. DISORDERED EATING
Contrary to popular belief,
eating disorders are not limited to classic eating disorders (anorexia
and bulimia), but occur on a spectrum ranging from calorie, protein
and/or fat restriction and weight control measures (diet pills,
laxatives, excessive, compulsive exercise in addition to normal
training regimen, self-induced vomiting) to full-blown anorexia and
bulimia.
Anorexia
Anorexia is a condition in which
a girl's diet does not allow her to maintain her weight within 15% of
the mean for girls her age and height. (Remember: daily requirements
for calories, carbohydrates, and protein are greater for athletes).
- Warning Signs:
- Sudden weight loss or gain
- Distorted body image
- Obsession with weighing oneself;
- Avoidance of social eating (i.e. a girl who likes to eat alone);
- Preoccupation
with food and dieting/unreasonable fear of being fat (girls on severe
diets in one Australian study were 18 times more likely to develop an
eating disorder; moderate dieters were 5 times more likely than those
who did not diet; Harvard researcher says 44% of high school girls and
15% of boys diet);
- Hair loss;
- Intolerance to cold
- Obsessive exercising
Bulimia
Bulimia is where a girl engages
in "binge eating" (i.e. eating too much uncontrollably in one sitting)
and then purging (vomiting, exercising intensely) to get rid of the
food just eaten.
- Warning Signs:
- frequent use of bathroom after eating
- Fluctuating weight
- Bloodshot eyes
- Swollen glands
- Swollen extremities
- Discolored teeth (i.e. eroded tooth enamel from frequent vomiting)
- Feelings of depression, guilt or shame about eating
- Suicide attempts
- Drug use
- Aches and pains
- Dramatic fluctuations in athletic performance
Serious Health Problems
Disordered eating results in
serious health problems, some of which are potentially fatal (the
mortality rate in severe cases can be as high as 10 to 15% from heart
failure, hormonal imbalances or suicide), including:
- heart problems such as irregular heart beat;
- muscle weakness or fatigue;
- fainting;
- loss of concentration in school work and athletics;
- irreversible bone loss;
- decrease in athletic performance (decrease in endurance, strength, reaction time, speed);
- depression
- fluid and electrolyte imbalance ; and
- suicide
Athletes at Risk
Though seen in all sports, those at greatest risk are those:
- Playing single sport on a year-round basis;
- Playing endurance sports (long distance running, swimming, cross-country skiing);
- Engaged in sports demanding a thin physical appearance (gymnastics, ice skating, ballet dancing, diving);
- Participating in sports with weight classifications (martial arts, rowing, wrestling);
- Whose parents are perfectionists and put too much pressure on their athletic daughters to succeed no matter what the cost.
Chicken or Egg?
The problem is that the
personality of an elite athlete and the personality of one prone to
eating disorders have a lot in common: an additive/compulsive
personality; a strong desire to do well/achieve perfection; a high
desire to please other people, a desire to push oneself to the limit,
and to work through pain without letting anyone know. In other words,
disordered eating in athletes presents a classic "chicken or egg"
question: do sports create eating disorders or do sports attract girls
who are already prone to eating disorders in the first place?
Conflicting Cultural/Peer Messages
Girls are also sent conflicting
messages by our culture and by their peers: that it is acceptable for
them to participate in sports, but they also need to maintain the
figure of a super model. The effect of societal pressure to be thin
combined with similar pressures in sport may be a higher incidence of
disordered eating behaviors and body shaping drug use (tobacco, diet
pills, diuretics, laxatives, amphetamines and anabolic steroids) in
athletic girls.
Reached Epidemic Levels
The number of athletes affected by eating disorders is staggering:
- Depending on the survey, eating disorders are thought to affect anywhere from 15 to 62% of girls.
- Among
teens and younger children, disordered eating has reached "epidemic
levels," according to researchers at the National Association of
Anorexia Nervosa and Associated Disorders.
- A 10-year study
revealed that some 7 million U.S. females and 1 million males have
eating disorders; that 10 percent reported that disorders began in
elementary school, with some children as young as 7 or 8 preoccupied
and dissatisfied with body image and weight.
- Fully forty percent of
9-year-olds in one Harvard study reported dissatisfaction with body
shape and as a remedy turned to dieting.
- A 1996 study reported disordered eating in 100% of elite female gymnasts, and osteoporosis in more than half.
2. AMENORRHEA
Healthy weight is important
for normal estrogen levels. When a female athlete's weight drops to an
unhealthy level (i.e. when the percentage of body fat falls below 17 to
18%), either through disordered eating and/or intense training,
menstruation may not start, may become irregular, or stop altogether.
It is a myth that the absence of menses simply proves that a female
athlete is training hard, and that amenorrhea is a positive adaptation
of girls to exercise.
"Primary" and "Secondary" Amenorrhea
A girl is deemed to have
"primary" amenorrhea if she has not begun to menstruate within 4.5
years after onset of breast development (menstruation usually begins
between ages 12 and 15 for non-athletic females and 13 to 15 ½ for
athletes). A girl who has not gotten her period for three to six
months, menstruates irregularly or with very light flow, or at
intervals longer than 35 days is considered to have "secondary"
amenorrhea.
Affects All Female Athletes
Amenorrhea effects girls
competing in all sports, but is most prevalent in competitive female
gymnasts, ninety percent of whom get their periods a year or two late.
Because a female's body
needs estrogen to absorb calcium for strong bones, not enough estrogen
can cause bones to lose thickness and strength, resulting in a greater
risk of stress fractures and osteoporosis. Research suggests that even
minor forms of menstrual dysfunction may adversely effect bone density
and lead to at least partially irreversible bone loss, although the
silver lining to delayed menstruation is that it may lower a girl's
risk of developing certain estrogen-related cancers.
3. OSTEOPOROSIS
A girl's teen years are a
critical time for developing normal, strong bones as they are the years
in which girls add half of their bone mass. Only ten percent of bone
mass is added after age twenty. Too much exercise can cause effect bone
mass and density, leaving a female athlete prone to increased risk of
stress fractures if a girl is not having regular periods and does not
have normal estrogen levels.
Prevention
- Balanced Diet.
First, and foremost, a proper balance of exercise, body weight, calcium
intake, Vitamin D (400 IU's daily) and estrogen is critical to prevent
osteoporosis (1500 mg. of calcium if irregular menses, 1200 mg. if
regular periods, either via 3 to 4 dairy products a day or
supplements). If necessary, you should take your daughter to a dietician or nutritionist who works with adolescent athletes.
- Screening.
To screen for the triad, make sure your daughter undergo a
pre-participation physical evaluation. It is essential that, in taking
the medical history, your daughter's pediatrician asks questions about
nutrition, menstruation, evidence of bone mineral loss (stress
fractures; Dual Energy X-Ray Absorptiometry scan), and body image .
Because athletes tend to be more honest about menstrual history and are
typically dishonest about eating patterns, an abnormal menstrual
history is a red flag for eating disorders and psychological issues
(this is why your daughter should keep track of her periods).
- No Pressure. As
a parent you should avoid pressuring your daughter to achieve an
unrealistically low body weight, such as by comments about appearance,
good or bad foods, dieting and nutrition (this advice holds true for
your sons as well, particularly swimmers and wrestlers) You should be
wary of coaches who conduct out-of-competition weigh ins or measurement
of body fat, especially public ones which can highlight for teenage
girls the already sensitive issue of their weight (one prominent
Southern California swim club that counts among its alumni numerous
Olympic gold medal winners labeled members with what it deemed too high
a body fat ratio as members of the "Blub Club"). One eating disorder
specialist theorizes that a relationship exists between eating
disorders and girls going through the natural separation in adolescence
of girls from their fathers because they are particularly vulnerable
during this time to viewing their coach as a substitute father figure.
Because girls tend to internalize criticism more than boys, if the
coach is critical of her weight, he or she can have a negative effect
on a female athlete's self-esteem.
- No Secrets.
Fourth, if you suspect that your daughter exhibits symptoms of one or
more elements of the triad, let her know that you want to help but that
you can't keep the matter a secret, nor can you solve the problem on
your own. If she is found to have disordered eating, experts recommend
a multidisciplinary treatment approach (doctor, nutritionist, mental
health professional).
Above all, be patient. Don't engage your daughter in a test of wills.
