Gender, school and academic year differences among Spanish university students at high-risk for developing an eating disorder: An epidemiologic study

BackgroundThe aim of this study was to assess the magnitude of the university population at high-risk of developing an eating disorder and the prevalence of unhealthy eating attitudes and behaviours amongst groups at risk; gender, school or academic year differences were also explored.MethodsA cross-sectional study based on self-report was used to screen university students at high-risk for an eating disorder. The sample size was of 2551 university students enrolled in 13 schools between the ages of 18 and 26 years. The instruments included: a social-demographic questionnaire, the Eating Disorders Inventory (EDI), the Body Shape Questionnaire (BSQ), the Symptom Check List 90-R (SCL-90-R), and the Self-Esteem Scale (RSE). The sample design is a non-proportional stratified sample by academic year and school. The prevalence rate was estimated controlling academic year and school. Logistic regression analysis was used to investigate adjusted associations between gender, school and academic year.ResultsFemale students presented unhealthy weight-control behaviours as dieting, laxatives use or self-induced vomiting to lose weight than males. A total of 6% of the females had a BMI of 17.5 or less or 2.5% had amenorrhea for 3 or more months. In contrast, a higher proportion of males (11.6%) reported binge eating behaviour. The prevalence rate of students at high-risk for an eating disorder was 14.9% (11.6–18) for males and 20.8% (18.7–22.8) for females, according to an overall cut-off point on the EDI questionnaire. Prevalence rates presented statistically significant differences by gender (p < 0.001) but not by school or academic year.ConclusionThe prevalence of eating disorder risk in university students is high and is associated with unhealthy weight-control practices, similar results have been found in previous studies using cut-off points in questionnaires. These results may be taken into account to encourage early detection and a greater awareness for seeking treatment in order to improve the diagnosis, among students on university campuses.

Factors Associated with Emotional Well-being in Primary and Secondary Caregivers of Patients with Eating Disorders

The aim of this study was to examine and identify the psychological, clinical and sociodemographic factors associated with emotional well-being by type of caregiver. A cross-sectional study was conducted among 185 primary caregivers and 92 secondary caregivers of patients with an eating disorder using the Hospital Anxiety and Depression Scale, the Experience of Caregiving Inventory and the Eating Disorders Symptom Impact Scale. According to a multiple regression analysis, a total of four models were obtained accounting for 42%-47% of the variance in emotional well-being. The variable that accounted for most of the variance of emotional well-being in three of the models was the impact of nutrition. Improving aspects of the relationships with the patients reduced anxiety and depression levels in primary caregivers. Similarly, a positive personal experience reduced depression in secondary caregivers. A higher education level was associated with decreased anxiety levels in both types of caregivers. Specific family interventions including both types of caregivers may be useful for providing emotional and adaptive personal coping skills.

Associated Factors of Unhealthy Eating Patterns among Spanish University Students by Gender

This study has examined bio-socio-demographic and psychopathological factors probably associated with unhealthy eating patterns among university students and to estimate a multifactorial model following the associated factors by gender. Adjusted odds ratios were calculated to describe associations on basis of Eating Disorder Inventory (EDI) stratified by gender in a representative sample of Spanish university students (n = 2551). The high EDI scorers for both sexes presented higher prevalence of dieting, body dissatisfaction, levels of psychopathology and lower self-esteem than the low EDI scorers. The results suggest that older students and higher self-esteem scores present lower scores in the EDI. In the female population, depression, paranoid dimension, dieting and body dissatisfaction were associated with population with unhealthy eating patterns. In the male sample, dieting, body dissatisfaction and interpersonal sensibility were also associated with unhealthy eating patterns. The results corroborate that abnormal eating patterns tend to affect specific vulnerable groups. We do not know the precise mechanisms through which these risk behaviors and attitudes, such as dieting or body dissatisfaction, may facilitate the later development of an eating disorder.
