LMS tables for waist circumference and waist-to-height ratio among Colombian children and adolescents: The FUPRECOL study

Background: Indices predictive of central obesity include waist circumference (WC) and waist-to-height ratio (WHtR). The aims of this study were 1) to establish a Colombian youth smoothed centile charts and LMS tables for WC and WHtR and 2) to evaluate the utility of these parameters as predictors of overweight and obesity. Method: A cross-sectional study whose sample population comprised 7954 healthy Colombian schoolchildren [boys n=3460 and girls n=4494, mean (standard deviation) age 12.8 (2.3) years old]. Weight, height, body mass index (BMI), WC and WHtR and its percentiles were calculated. Appropriate cut-offs point of WC and WHtR for overweight and obesity, as defined by the International Obesity Task Force (IOTF) definitions, were selected using receiver operating characteristic (ROC) analysis. The discriminating power of WC and WHtR was expressed as area under the curve (AUC). Results: Reference values for WC and WHtR are presented. Mean WC increased and WHtR decreased with age for both genders. We found a moderate positive correlation between WC and BMI (r= 0.756, P < 0.01) and WHtR and BMI (r= 0.604, P < 0.01). The ROC analysis showed a high discrimination power in the identification of overweight and obesity for both measures in our sample population. Overall, WHtR was slightly a better predictor for overweight/obesity (AUC 95% CI 0.868-0.916) than the WC (AUC 95% CI 0.862-0.904). Conclusion: This paper presents the first sex- and age-specific WC and WHtR percentiles for both measures among Colombian children and adolescents aged 9–17.9 years. By providing LMS tables for Latin-American people based on Colombian reference data, we hope to provide quantitative tools for the study of obesity and its comorbidities.

Identification with the neighborhood: Discrimination and neighborhood size

This paper analyzes the impact of a geographical social grouping (neighborhood) and its relative perceived size in the spontaneous group’s identiication level and place satisfaction, as well as the intensity of and motives for discrimination against inhabitants of other places. Two studies are presented: an experimental one using the minimal group categorization paradigm and an onsite investigation of a city neighborhood. Consistent with the predictions, the results showed that smaller neighborhoods reported higher identiication and satisfaction with the place of residence, as well as higher discrimination of other neighborhoods. In line with the optimal distinctiveness theory (ODT), the indings showed that the motivation for discrimination varies as a function of the in-group size. Thus, the members of larger groups discriminate by increasing the diferentiation between the in-group and the out-group, whereas the members of smaller groups increased the value of the in-group. Furthermore, the results were consistent with a social identity theory and ODT explanation of diverse research that shows the non-trivial nature of geographical bounded social grouping and its importance in a diverse set of contexts and its impact in inter-neighborhood relationships.

Derechos humanos y migración: el caso de la Corte Interamericana de Derechos Humanos

ResumenLa Corte Interamericana con las dos opiniones consultivas sobre la situación de la clase trabajadora migrante en los Estados Unidos, está enfatizando el hecho que los Estados tienen la obligación general de respetar y garantizar los derechos fundamentales. Con este propósito deben adoptar medidas positivas, evitar tomar iniciativas que limiten o conculquen un derecho fundamental, y suprimir las medidas y prácticas que restrinjan o vulneren un derecho fundamental. El incumplimiento mediante cualquier tratamiento discriminatorio, de la obligación general de respetar y garantizar los derechos humanos, le genera responsabilidad internacional.El principio de igualdad y no discriminación posee un carácter fundamental para la salvaguardia de los derechos humanos, tanto en el derecho internacional como en el interno.El principio fundamental de igualdad y no discriminación forma parte del derecho internacional general, en cuanto es aplicable a todo Estado, independientemente de que sea parte o no en determinado tratado internacional. En la actual etapa de la evolución del derecho internacional,este principio ha ingresado en el dominio del jus cogens, es decir de principios universalmente aceptados que no admiten posición en contra. El principio fundamental de igualdad y no discriminación, revestido de carácter imperativo, acarrea obligaciones de protección que vinculan a todos los Estados y generan efectos con respecto a terceros, inclusive particulares.Palabras clave: migración, derechos humanos, corte interamericana, opinión consultiva. AbstractThe Inter-American Court with the two advisory opinions on the situation of migrant workers in the United States is emphasizing the fact that the United States has the obligation to respect and guaranteefundamental rights. With this purpose, it should take positive actions, avoiding taking initiatives to limit or infringe a fundamental right, and eliminate measures and practices that restrict or violate afundamental rights. Failure by any discriminatory treatment of the general obligation to respect and guarantee human rights, gives rise to international responsibility. The principle of equality and nondiscrimination is fundamental for the protection of human rights both in international law and the domestic. The fundamental principle of equality and non discriminationforms part of the general international law as applicable to all States, regardless of party or a specific international treaty. At the current stage of evolution of international law, the fundamentalprinciple of equality and non-discrimination has entered the domain of jus cogens, ie of universally accepted principles that do not support position against it. The fundamental principle of equality andnondiscrimination, a peremptory nature, entails obligations to protect that bind all States and generate effects on third parties, including individuals.Keywords: migration, human rights, Inter-American Court, advisory opinion.

Feminist Disability Theory: Domestic Violence Against Women with a Disability

Women with a disability continue to experience social oppression and domestic violence as a consequence of gender and disability dimensions. Current explanations of domestic violence and disability inadequately explain several features that lead women who have a disability to experience violent situations. This article incorporates both disability and material feminist theory as an alternative explanation to the dominant approaches (psychological and sociological traditions) of conceptualising domestic violence. This paper is informed by a study which was concerned with examining the nature and perceptions of violence against women with a physical impairment. The emerging analytical framework integrating material feminist interpretations and disability theory provided a basis for exploring gender and disability dimensions. Insight was also provided by the women who identified as having a disability in the study and who explained domestic violence in terms of a gendered and disabling experience. The article argues that material feminist interpretations and disability theory, with their emphasis on gender relations, disablism and poverty, should be used as an alternative tool for exploring the nature and consequences of violence against women with a disability.
