Background: Body image disturbance is an increasing probleminWestern societies and is associated with
a number of mental health outcomes including anorexia, bulimia, bodydysmorphia, and depression. The aim of
this study was to assess the association between body image disturbance and the incidence of depression.
Methods: This study included 10,286 participants from a dynamic prospective cohort of Spanish university graduates,whowere followed-up for a median period of 4.2 years (Seguimiento Universidad de
Navarra – the SUN study). The key characteristic of the study is the permanently open recruitment that
started in 1999. The baseline questionnaire included information about body mass index (BMI) and the
nine figure schemes that were used to assess body size perception. These variables were grouped
according to recommended classifications and the difference between BMI and body size perception was
considered as a proxy of body image disturbance. A subject was classified as an incident case of depression
if he/she was initially free of depression and reported a physician-made diagnosis of depression and/or the
use of antidepressant medication in at least one of the follow-up questionnaires. The association between body image disturbance and the incidence of depression was estimated by calculating the multivariable
adjusted Odds Ratio (OR) and its 95% Confidence Interval (95% CI), using logistic regression models.
Results: The cumulative incidence of depression during follow-up in the cohort was 4.8%. Men who underestimated their body size had a high percentage of overweight and obesity (50.1% and 12.6%, respectively), whereas women who overestimated their body size had a high percentage of
underweight (87.6%). The underestimation exhibited a negative association with the incidence of depression among women (OR: 0.72, 95% CI: 0.54 – 0.95), but this effect disappeared after adjusting for possible confounding variables. The proportion of participants who correctly perceived their body size was high (53.3%) and gross misperception was seldom found, with most
cases selecting only one silhouette below (42.7%) or above (2.6%) their actual BMI.
Conclusion: We found no association between body image disturbance and subsequent
depression in a cohort of university graduates in Spain.
