Eating disorders are characterized by clinically significant disturbances in body image and eating behaviors (
Smolak & Striegel-Moore, 2001). The lifetime estimated prevalence in females for anorexia nervosa (AN) ranges from 0.6% to 4.0% and from 1.2% to 5.9% for bulimia nervosa (BN) (
Hudson, Hiripi, Pope, & Kessler, 2007). Although AN and BN are more prevalent in females than males, this discrepancy is smaller for sub-threshold binge eating disorder (BED) (0.6% women and 1.9% men) and for any binge eating (4.9% women and 4.0% men) (
Hudson, Hiripi, Pope, & Kessler, 2007).
Most studies that have evaluated the prevalence and treatment of these disorders have focused primarily on non-minority populations. Therefore, theoretical models, interventions, and instruments have been developed based on particularities of Western culture (
Smolak & Striegel-Moore, 2001). The dearth of comprehensive data regarding eating disorders in ethnically diverse samples has perpetuated the misperception that ethnic minority girls and women do not experience symptoms of eating disorders (
Smolak & Striegel-Moore, 2001). However, community and college student studies reveal that eating disorders do exist among minority groups (
Cachelin, Rebeck, Veisel & Striegel-Moore, 2001;
Franko, Becker, Thomas & Herzog, 2007).
The available data on Latinos (
Gentile, Raghavan, Rajah & Gates, 2007;
Granillo, Jones-Rodriguez, & Carvajal, 2005;
Hiebert, Felice, Wingard, Muñoz & Ferguson, 1988;
Pumariega, 1986;
Santos, 1996) reveal that the prevalence of BN is similar to that reported in Caucasian samples, although awareness of this research is limited. Early studies of adolescents documented that prevalence of disordered eating behaviors is similar in Hispanic and Caucasian youth (
Lachenmeyer & Muni-Brander, 1988;
Smith & Krejci, 1991;
Snow & Harris, 1989) and Hispanic, Asian- American, and Native- American girls tended to report similar or even greater concerns and behaviors than white adolescent girls (
Neumark-Sztainer, Croll, Story, Hannan, French & Perry, 2002).
Granillo and colleagues (2005) analyzed data from the Add Health study to estimate the occurrence of eating disorders and body image disturbances in a sample of Latina adolescents. For all Latinas, 2.5% reported a body mass index (BMI) of 17 kg/m
2 or lower, 5.5% reported amenorrhea, 53.3% reported current dieting, and 1.9% reported bulimic symptomatology. Compared with the non-Latina Add Health participants, Latinas were less likely to be low weight, had higher dietary restraint, and were similar in rates of amenorrhea and bulimic symptomatology.
Recently,
Alegría and collaborators (2007) conducted a survey study with Latinos ages 18 and older living in the United States (U.S.). The sample consisted of 2,554 (1,127 men and 1,427 women) English- and Spanish-speaking adults from various ethnic backgrounds. The authors reported an estimated lifetime prevalence of 0.08% for AN, 1.61% for BN, 1.92% for BED, and 5.61% for any binge eating. The twelve-month prevalence estimates were 0.03% for AN, 0.82% for BN, 0.90% for BED, and 2.73% for any binge eating. Regarding sex, the lifetime prevalence of any binge eating was 5.43% for men and 5.80% for women and for BN were 1.34% for men and 1.91% for women.
Additionally, studies of college students indicate that the prevalence of eating disorders is similar or greater in Latina populations than in white populations. For example, data from the National Eating Disorders Screening Program, conducted on over 600 college campuses in the U.S., found that self-reported eating disorder symptoms were higher in Latino/a students than in African- American, Asian, and white students. Moreover, Latino/a participants were significantly less likely to be referred for further evaluation than were white participants (
Becker, Franko, Speck, & Herzog, 2003;
Franko, Becker, Thomas & Herzog, 2007).
Eating disorders on college campuses represent a serious, yet understudied mental health issue (
Hoyt & Ross, 2003). The college population is at elevated risk for eating disorders due to age-related, developmental, and environmental factors (
Hoyt & Ross, 2003). Recent data indicate a high prevalence of eating disorders among women enrolled in colleges and universities throughout the U.S. An estimated 1–4% meet the full DSM-IV criteria for AN, and an additional 35–70% report behaviors or symptoms that increase the risk of eating disorders (
Hoyt & Ross, 2003). Studies of eating disorders in college student populations are a key element in the process of raising awareness about the disorders, which may result in the development of effective diagnosis and treatment. It is also important to note that prevalence studies conducted on college campuses with diverse samples are few in number (
Aruguete, DeBord, Yate & Edman, 2005;
Hoerr, Bokran, Lugo, Bivins & Keast, 2002;
Mintz, O’Halloran, Mulholland & Schneider, 1997). A recent study underscores the need to examine eating disorders in Latino/a samples.
Gentile, Raghavan, Rajah and Gates (2007) conducted a survey in a diverse ethnic freshmen student sample (45.8% Hispanic or Latino/a; 24.5% African American/Afro-Caribbean; 19.4% white) and found that the Latino/a group was more likely to report an eating disorder (12.6%) than the African American/Afro Caribbean group (5.0%) or whites (6.1%).
Sex differences reporting greater eating concerns in women than men are well documented, but a recent study of undergraduate students found that although women were 2.3 times more likely than men to report compulsive eating (
Guidi, Pender, Hollon, Zisook, Schwartz, Pedrelli, et al., 2009), men were more likely to engage in compulsive exercise (23.4%) than women (13.4%). Moreover, a full 20% of male collegiate athletes reported having eating disturbances including binge eating, use of laxatives, diuretics and self induced vomited (
Petrie, Greenleaf, Reel & Carter, 2009). These data suggest the importance of including men in epidemiologic studies of eating disturbances.
Eating disorders are associated with depression, low self-esteem, anxiety, perfectionist and obsessive-compulsive traits, disturbances in social functioning (
Blinder, Camella & Sanathara,2006;
Kaminska & Rybakowski, 2006;
Muuss, 1986;
Woodside & Stab, 2006), and suicide attempts (
Franko & Keel, 2006). The comorbidity between eating and mood disorders has important implications for assessment and treatment and has rarely been studied with minority samples (
Franko & Striegel-Moore, 2002;
Franko, Striegel-Moore, Bean, Tamer, Kraemer, et al., 2005).
The primary objective of this investigation was to conduct the first study of the prevalence of eating disorder symptoms in freshmen students at the University of Puerto Rico. The second objective was to evaluate depressive symptoms in the sample. The research questions were: (1) What is the prevalence of clinically significant eating disorder symptoms and behaviors in first year college students in Puerto Rico?; (2) How do participants in the eating disorder symptom group (those scoring above the cut-off on both or either screening measures of eating disorders) and the referent group (those scoring below the cut-off on screening measures of eating disorders) differ in regard to eating behaviors, depressive symptoms, weight, and BMI; and (3) How do men and women differ in regard to eating disorder behaviors?
