the corresponding point in
the graph of � = 3�(� − 2).
Problem 7: Jules can be paid in one of the two ways for doing
yard work:
Plan A: $324 plus $10.75 per hour
Plan B: $25.25 per hour

Problem 8: Let A = (-7, 3) be a point. Find the point B that is
symmetric to A with respect
to the origin.
Problem 9: Find the point-slope equation of the line with slope
m=-3/8 and passing
through (5,6).
Problem 10: Before taxes, Jules earned $564 one week after
working 30 hours at his regular
wage, 6 hours at time-and-a-half on Saturday, and 4 hours at
double-time on Sunday. What is
Jules’ hourly wage?

Introduction
The selected research topic is eating disorders in males.
Typically, statistics find that the victims of eating disorders
such as bulimia nervosa or anorexia nervosa are predominantly
among the female population. However, eating disorders may be
presented by the male population as well; although a hidden
population, it is perhaps due to the effects of social media,
steroids, bodybuilding, and with societal pressures that the male
population may feel the need to present more masculine in order
to achieve social status (Pope et al, 1993). The statistics,
endocrinopathies, and etiologies of eating disorders in males are
researched, ideas in which are significantly important to
understand in order to combat against this painful disease. By
acknowledging the risk factors and the effects eating disorders
can bring about, especially within this hidden population,
society itself can bring about a more effective means of
increasing nutrition and promoting healthy habits in order to
decrease the significance of body dysmorphia.

I. (2016). The endocrinopathies
of male anorexia nervosa: case series. AACE clinical case
reports, 2(4), e351-e357.
Skolnick et al’s study elucidated the clinical characteristics of
anorexia nervosa in male subjects specifically, and their
subjects’ endocrinopathies or hormonal imbalances (2016).
Skolnick presented four cases (two cases at the Mount Sinai
Hospital and two cases at the Long Island Jewish Hospital) with
hormonal imbalances due to anorexia. The four men presented
caloric and protein malnutrition and thus experienced various
levels of systemic complications. Diseases such as
hypogonadotropic hypogonadism (disease in which the body
produces little to no testosterone), hypercortisolemia (condition
in which the pituitary gland produces too much cortisol that
causes abnormalities within the body), and nonthyroidal illness
syndrome (abnormal thyroid functioning). Such complications
as a result of the eating disorder, anorexia, also brought about
within the subjects, heart complications (2016). The subjects’
age of diagnosis were around 21 years old. Although most of the
systemic complications lessened in intensity as the subjects
improved their nutritional habits, their more severe issues such
as hypogonadism persisted.
The results from the research indicate that anorexia nervosa
does cause a variety of endocrinopathies in male victims.
Although the degree to which the disease causes complications
vary, maintaining a healthy caloric intake and continuing
healthy habits are necessary for victims to stay healthy.

nervosa and “reverse anorexia”
among 108 male bodybuilders. Comprehensive
psychiatry, 34(6), 406-409.
Pope et al’s study discovered that male bodybuilders have a

significant potential of becoming a victim of an eating disorder
(1993). Pope et al’s study highlighted the effects of anabolic
steroids (synthetic steroids that work to promote muscle growth
by acting as a makeshift testosterone) on a male bodybuilder’s
mentality. By studying 108 bodybuilders through the use of the
Structured Clinical Interview through the DSM-III (which
studied an individual’s lifestyle and history), Pope et al
identified that 55 utilized anabolic steroids while the other 53
did not. A significant three subjects were reported to have
anorexia nervosa (2.8%, rather than the 0.02% rate of American
men), while nine other subjects reported to have “reverse
anorexia” symptoms (1993). The nine subjects with “reverse
anorexia” believed they were too weak in stature, when in
reality, as compared to most people, they were large and
muscular. The nine subjects were also steroid users, while four
subjects of the nine began using the steroids in order to be
perceived as larger.
The results from the research found that eating disorders, body
dysmorphia, and overall body image complications may be
significant in male bodybuilders. The use of anabolic steroids is
a trend that may bring about new statistics in the way people
perceive their body as well, as some of the subjects began to
utilize the steroids as a result of their body dysmorphia.

disorders in males: A report on
135 patients. American Journal of Psychiatry, 154(8), 1127-
1132.
Carlat et al’s study identified the statistics and etiology of
eating disorders among males who were treated at the
Massachusetts General Hospital, Boston, from January 1, 1980
to December 31, 1994 (1997). Carlat et al’s research discovered
that through the utilization of the DSM-IV criteria, 135 males
(with the mean age of 19 years old) were found to have a
various eating disorder. 62 (46%) had bulimia nervosa, 30

(22%) had anorexia nervosa, and 43 (32%) had a various eating
disorder but not necessarily one that was distinctly identified
(1997). Carlat et al’s research also found that 42% of the
bulimic patients were homosexual or bisexual, and 58% of the
anorexia patients were asexual. In addition, about half of the
patients had a major depressive disorder, struggled with
substance abuse, and some also suffered from a personality
disorder (1997).
The results from the research found that homosexual and
bisexual orientations may be associated as a risk factor for an
eating disorder, especially with bulimia nervosa. In addition, as
the mean age of onset for the patients was 19 years old, it may
be found that it is at a young man’s age that they are at the
greatest potential of contracting an eating disorder.
