Summary OBJECTIVE: Undertake a meta-analysis to provide a quantitative synthesis of longitudinal studies that assessed the direction of effects between eating pathology and depression. A second aim was to use meta-regression to account for heterogeneity in terms of study-level effect modifiers. METHOD: A systematic review was conducted on 42 studies that assessed the longitudinal relationship between eating pathology and depression. Of these 42 studies, multilevel random-effects meta-analyses were conducted on 30 eligible studies. RESULTS: Meta-analysis results showed that eating pathology was a risk factor for depression (rm  = 0.13) and that depression was a risk factor for eating pathology (rm  = 0.16). Meta-regression analyses showed that these effects were significantly stronger for studies that operationalized eating pathology as an eating disorder diagnosis versus eating pathology symptoms, and for studies that operationalized the respective outcome measure as a categorical variable (e.g., a diagnosis of a disorder or where symptoms were "present"/"absent") versus a continuous measure. Results also showed that in relation to eating pathology type, the effect of an eating disorder diagnosis and bulimic symptoms on depression was significantly stronger for younger participants. DISCUSSION: Eating pathology and depression are concurrent risk factors for each other, suggesting that future research would benefit from identifying factors that are etiological to the development of both constructs. RESUMEN OBJETIVO: Llevar a cabo un meta-análisis para proporcionar una síntesis cuantitativa de los estudios longitudinales que evaluaron la dirección de los efectos entre la alimentación patológica y la depresión. Un segundo objetivo fue utilizar la meta-regresión para dar cuenta de la heterogeneidad en términos de modificadores del efecto a nivel de estudio. MÉTODO: Una revisión sistemática se llevó a cabo en 42 estudios que evaluaron la relación longitudinal entre la alimentación patológica y la depresión. De estos 42 estudios, se realizaron meta-análisis de multinivel de efectos aleatorios en 30 estudios elegibles. RESULTADOS: Los resultados del meta-análisis mostraron que la alimentación patológica era un factor de riesgo para depresión (rm=0.13) y que la depresión era un factor de riesgo para la alimentación patológica (rm=0.16). Los análisis de meta-regresión mostraron que estos efectos eran significativamente más fuertes para estudios que operacionalizaban la alimentación patológica como un diagnóstico de trastorno de la conducta alimentaria versus síntomas de alimentación patológica, y para los estudios que operacionalizaban la medida respectiva de resultado como una variable categórica (e.g., un diagnóstico de trastorno o cuando los síntomas estaban "presentes"/"ausentes") versus una medida continua. Los resultados mostraron que en relación al tipo de alimentación patológica, el efecto de un diagnóstico de trastorno de la conducta alimentaria y síntomas bulímicos en la depresión era significativamente más fuerte para participantes más jóvenes. DISCUSIÓN: La alimentación patológica y la depresión son factores de riesgo concurrentes uno para el otro, lo que sugiere que la investigación futura se beneficiaría de identificar factores que son etiológicos al desarrollo de ambos constructos. © 2015 Wiley Periodicals, Inc.
