    <abstract xml:lang="en">Abstract
Introduction. Scaling in obesity classes increases its effect on medical comorbidities and psychiatric symptoms. Anxiety and depression have a significant effect on treatment adherence and weight loss.
Objective. This study had three aims: a) to evaluate the prevalence of psychiatric symptoms; b) to evaluate the interactions between obesity classes and demographic variables in relation to psychiatric symptoms; and c) to analyze the interactions between obesity classes, demographic variables, and psychiatric symptoms in association with medical comorbidities in a sample of obese individuals seeking treatment for weight loss.
Method. Medical record review of 22 weight loss clinics during January-December 2014. Binomial logistic regression was carried to assess univariate associations, second- and third-order interactions.
Results. Total sample was composed of 13,305 patients, mostly women (82.04%), married (53.66%), with elementary education (38.6%), mean body max index was 34.94 (SD = 4.39). The most prevalent psychiatric symptoms were anxiety (45.21%) and depression (16.36%). When analyzing interactions, it was found that men with class II obesity had higher odds for alcohol use (OR 1.56, IC 95% 1.10-2.22), and participants with obesity class III and married had more probability of diabetes II (OR 1.53, IC 95% 1.06-2.19).
Discussion and conclusion. Results show the complexity of the relation between demographic variables, psychiatric symptoms, medical comorbidities and obesity, underscoring the need to tailor treatments based in such variables, to promote adherence and weight loss.</abstract>
    <trans-abstract xml:lang="es">Resumen
Introducci&oacute;n. El incremento en el grado de obesidad se asocia con comorbilidades m&eacute;dicas y los s&iacute;ntomas psiqui&aacute;tricos. La ansiedad y la depresi&oacute;n afectan la adherencia al tratamiento de la obesidad y la reducci&oacute;n de peso corporal.
Objetivo. El estudio tuvo tres objetivos principales: a) Evaluar la prevalencia de s&iacute;ntomas psiqui&aacute;tricos; b) evaluar las interacciones entre grados de obesidad, variables demogr&aacute;ficas y s&iacute;ntomas psiqui&aacute;tricos; c) analizar las interacciones entre grados de obesidad, s&iacute;ntomas psiqui&aacute;tricos y comorbilidades m&eacute;dicas.
M&eacute;todo. A trav&eacute;s de revisi&oacute;n de expedientes m&eacute;dicos de 22 cl&iacute;nicas de reducci&oacute;n de peso entre enero-diciembre de 2014. Se analiz&oacute; a trav&eacute;s de regresi&oacute;n log&iacute;stica univariada y evaluando interacciones de segundo y tercer orden.
Resultados. La muestra total fue de 13305, mayormente mujeres (82.04%) la mayor&iacute;a son casados (53.66%) con escolaridad de secundaria (38.6%) y preparatoria (36.7%), el IMC promedio fue de 34.94 (SD = 4.39). Las comorbilidades m&aacute;s prevalentes fueron s&iacute;ntomas de ansiedad (45.21%) y depresi&oacute;n (16.36%). Al analizar las interacciones los hombres con obesidad tipo II tuvieron mayor probabilidad de consumo de alcohol (OR 1.56 IC 95% 1.10-2.22), y los participantes con obesidad tipo III y casados tuvieron mayor probabilidad de diabetes (OR 1.53 IC 95% 1.06-2.19).
Discusi&oacute;n y conclusi&oacute;n. Los resultados muestran la compleja relaci&oacute;n entre variables demogr&aacute;ficas, obesidad, s&iacute;ntomas psiqui&aacute;tricos y comorbilidades, implicando la necesidad de desarrollar programas de tratamiento que tomen en cuenta dichas variables para promover la adherencia al tratamiento y la reducci&oacute;n de peso.</trans-abstract>
