Relationship between body image disturbance and incidence of depression: the SUN prospective cohort

[EN] Background: Body image disturbance is an increasing problem in Western societies and is associated with a number of mental health outcomes including anorexia, bulimia, body dysmorphia, 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, who were 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.

Insatisfacción corporal y actitudes alimentarias anómalas en bailarines y bailarinas

[ES] El riesgo de desarrollar trastornos de conducta alimentaria (TCA) es mayor en mujeres que en hombres de muestras comunitarias. Sin embargo, no existen datos suficientes que reflejen que esta diferencia también se mantenga en poblaciones especiales como por ejemplo, los bailarines/as. En este estudio se comparan estudiantes de población general y bailarines de ambos sexos para conocer si existen diferencias entre ellos respecto a sus actitudes alimentarias einsatisfacción con la imagen corporal.

Imagen corporal y satisfacción corporal en adultos: diferencias por sexo y edad

[ES] Existe en la actualidad un gran interés por la apariencia del cuerpo tanto por razones estéticas como de salud, no sólo en mujeres y jóvenes, sino también en hombres y adultos de mayor edad. La importancia de este fenómeno radica, entre otras razones, en que se asocia a conductas saludables o de riesgo, incluyendo la práctica de ejercicio físico. Objetivos: Conocer la Imagen Corporal (IC) a través de tres percepciones corporales: Imagen corporal actual (ICA), ideal (ICI) y social (ICS), así como la Satisfacción Corporal (SC) de una muestra de adultos de 18 a 40 años, y explorar posibles diferencias por sexo y edad.
