IntroductionIntimate Partner Violence (IPV) is a public health concern associated with multiple adverse health outcomes, including psychological distress (PD).ObjectiveTo assess the association of IPV and psychological distress, and the mediation of tobacco and alcohol consumption in a national representative sample from Mexico.Material and methodsData from the Encuesta Nacional de Consumo de Drogas, Tabaco y Alcohol (ENCODAT) were analyzed. The sample included 34,864 people between the ages of 12 and 65 with a partner. Using Structural Equation Modeling (SEM), the association between IPV, use alcohol, tobacco and psychological distress was measured.ResultsThe population was composed of women (51.9%) and men (48.1%); 15.1% (women = 18.2% and men = 11.9%) reported IPV in the last year. The prevalence of psychological distress in the last year was 3.3%, being 3.8% in women, and 2.7% in men. Results from the SEM in women indicated a direct positive effect of the IPV construct on psychological distress (β = 0.298, p < 0.01); these findings confirmed that IPV tended to systematically increase psychological distress. Likewise, the presence of IPV increased the consumption of tobacco (β = 0.077, p < 0.01) and alcohol (β = 0.072, p < 0.01). The SEM results in men showed that alcohol and tobacco consumption tended to increase in the presence of IPV (β = 0.121, p < 0.01, and β = 0.086, p < 0.01, respectively), and in turn, alcohol consumption and tobacco tended to increase psychological distress (β = 0.024, p < 0.01, and β = 0.025, p < 0.01, respectively).ConclusionThis study indicated that in women, IPV had a direct effect on psychological distress and on alcohol and tobacco consumption. Meanwhile in men, alcohol and tobacco consumption had a mediating effect between IPV and psychological distress. The empirical findings of this study will contribute toward the design of public health policies for the prevention and attention of IPV, alcohol and tobacco consumption, and consequently address the mental health consequences derived from these problems.

La percepción de la imagen corporal se ha asociado al desarrollo de trastornos de la conducta alimenticia, como anorexia nerviosa, bulimia y megarexia. Es importante evaluar en la adolescencia el estado de nutrición y prevenir tanto el bajo peso como el sobrepeso, la obesidad y los trastornos mencionados. El objetivo de este estudio fue determinar los factores antropométricos y sociodemográficos que se relacionan con la percepción de la imagen corporal en adolescentes. Se realizó un estudio transversal en 169 estudiantes de secundaria en quienes se relacionaron factores sociodemográficos y antropométricos con la percepción conceptual y visual de la imagen corporal, a partir de modelos de regresión logística multivariada. Los principales resultados fueron que, cuando el estado de nutrición es considerado normal, la percepción de la imagen corporal es mejor que cuando presentan bajo peso, sobrepeso u obesidad.
