Summary:Although anxiety seems to be a constant in patients with eating disorders (ED), little is known about its interaction with other variables. Therefore, the main objective of this study was to compare the risk of anorexia nervosa (AN) and bulimia nervosa (BN) based on the sex of participants, degree of anxiety and city of residence. The study is a non-experimental and cross-sectional design. The sample was nonrandom and consisted of 857 college students (67% female and 33% male) with a mean age of 21.96 years (SD = 4.84), 42% were Mexico City residents and 58% were from Ensenada city. Participants completed two self-report scales, one for assessing risk of AN and BN, and other to measure anxiety. The findings show that the degree of anxiety differs according to the city of residence, being higher in Ensenada city. In addition, a significant interaction was found between the variables; for instance, the risk of BN in Ensenada city residents increases as anxiety increases. Therefore, it is confirmed not only the importance of sex and anxiety on eating disorders, but also the interaction of these two variables with the city of residence.  Aunque la ansiedad parece ser una constante en los pacientes con trastorno de la conducta alimentaria , poco se sabe sobre su interacción con otras variables. Por tanto, el objetivo principal de este estudio fue comparar el riesgo de anorexia nerviosa (AN) y bulimia nerviosa (BN) en función del sexo, el grado de ansiedad y la ciudad de residencia. Se trabajó con un diseño no experimental-transversal y una muestra no probabilística conformada por 857 estudiantes universitarios (67% mujeres y 33% hombres), con edad promedio de 21.96 años (DE = 4.84), el 42% residentes en la Ciudad de México y el 58% en la ciudad de Ensenada. Los participantes completaron dos escalas de autoreporte, una para evaluar riesgo de AN y BN, y otra para medir la ansiedad. Los hallazgos evidencian que el grado de ansiedad difiere en función de la ciudad de residencia, siendo mayor en Ensenada. Además, se encontró una interacción significativa entre las variables; por ejemplo, en los residentes en la ciudad de Ensenada, el riesgo de BN se incrementa cuando la ansiedad aumenta. Por tanto, se confirma no sólo la relevancia del sexo y la ansiedad sobre los trastornos de la conducta alimentaria, si no también de la interacción de dichas variables con la ciudad de residencia.
