“…on BMI are likely mediated through dietary and physical activity patterns. An example of a mediational model of the influence of a community-based prevention intervention on BMI through walkability is shown in Figure 1 (G. F. Dunton, Intille, Wolch, & Pentz, 2012;Durand, Andalib, Dunton, Wolch, & Pentz, 2011;Jerrett et al, 2013).…”

Recent introduction of quantile regression methods to analysis of epidemiologic data suggests that traditional mean regression approaches may not suffice for some health outcomes such as Body Mass Index (BMI). In the same vein, the traditional mean-based approach to mediation modeling may not be sufficient to capture the potentially different mediating effects of behavioral interventions across the outcome distribution. By combining methods for estimating conditional quantiles with traditional mediation modeling techniques, mediation effects can be estimated for any quantile of the outcome distribution (so-called quantile mediation effects). Estimation and inference techniques for quantile mediation effects are compared through simulation studies, and recommendations are given. The quantile mediation methods are further compared with the traditional mean-based regression approaches to mediation analysis through analysis of data from Healthy Places, a trial that is examining the effects of the community-built environment on resident obesity risk. We found the magnitudes of indirect (mediating) effects of walkability on BMI and waist circumference were substantially larger for the upper quantiles compared with the median or mean. Results suggest that restricting the examination of mediation to the mean of the outcome distribution provides an incomplete picture of proposed mediating mechanisms and in some cases may miss important mediational relationships to outcomes.

“…De estos estudios se desprende cómo las áreas urbanas de baja densidad, con usos de suelo segregados, escasez de servicios en proximidad, reducidas opciones de transporte público y espacios públicos de baja calidad, aumentan la dependencia del vehículo privado y reducen las probabilidades para realizar desplazamientos relacionados con la actividad física (Bahrainy & Khosravi, 2013;Brown et al, 2013;Jerrett et al, 2013).…”

“…El impacto más controvertido del fenómeno de la dispersión urbana es su influencia en la elección de modos de transporte específicos (Travisi, Camagni, and Nijkamp 2010). La proliferación de áreas urbanas de baja densidad, con predominio de usos de suelo segregados y escasez de servicios en proximidad, ha aumentado las distancias al área urbana central (Zhao et al 2010), reduciendo las posibilidades para realizar desplazamientos no motorizados (Bahrainy y Khosravi, 2013;Brown et al, 2013;Ewing et al, 2014;García-Palomares, 2010;Jerrett et al, 2013).…”

RESUMENLa promoción del transporte público y de modos de transporte no motorizados tiene como objetivo reducir la dependencia del vehículo privado. Muchos estudios, realizados principalmente en países anglosajones, han analizado la posible relación entre la dispersión urbana y el uso de modos de transporte, aunque a escala metropolitana. Sin embargo, la evidencia de esta relación no ha sido suficientemente evaluada en países mediterráneos. El objetivo del presente estudio es evaluar, de manera empírica, la influencia de la dispersión urbana en la elección de modos de transporte específicos a escala sub-municipal.Palabras clave: dispersión urbana, modos de transporte, transporte no motorizado, regresión ordinal PLUM.
