    La estrecha correlación entre sintomatología depresiva y elevado Índice de Masa Corporal (IMC), y entre apoyo familiar y bajo IMC demostrada por algunos estudios es debatible. Nuestra hipótesis es que, durante la juventud, los aspectos positivos del apoyo familiar actúan como mediadores en la asociación entre depresión y peso corporal, siendo responsables del elevado IMC. Exploramos si el apoyo familiar correlaciona con depresión y si sintomatología depresiva se correlaciona con obesidad. La relación entre depresión y apoyo familiar fue significativa (r = -0.44, p = 0.004). La relación entre depresión e IMC fue significante exclusivamente en mujeres. Cuando el apoyo familiar fue incluido en la ecuación, el efecto de depresión sobre IMC se redujo a niveles no significativos. Esto indica que el apoyo familiar es un mediador parcial entre depresión y obesidad juvenil. Exponemos la necesidad de realizar análisis adicionales para discernir vínculos entre parámetros psicosociales e indicadores de salud.

    The relationship between depressive symptomatology and elevated Body Mass Index (BMI), and between family support and low BMI is controversial. There are unanswered questions about the relationship between these three variables We tested the hypothesis that positive family support mediates the association between depression and bodyweight responsible for overweight and obesity in Mexican youth. We explored if family support correlated with depression and if depressive symptomatology correlated with obesity. Our results indicate that the relationship between depression and family support was significant (r = -0.44, p = 0.004). A significant relationship between depression and BMI was found only in women. When family support is included into the equation, the effect of depression on BMI disappeared. This observation indicates family support is a partial mediator between depression and obesity in adolescents. Our results are important and prompt an extended analysis of likely causative links between psychosocial parameters and health descriptors.
