Se planificó un estudio observacional, transversal y analítico de una población de 380 estudiantes de menos de 19 años (87,96% del total de esas edades) que ingresaron a carreras de Licenciatura, Técnico y Técnico Superior Universitario, calendario B, del Centro Universitario del Sur de la Universidad de Guadalajara, México en agosto de 2006. El 66,6% pertenecía al género femenino; 99,2% tenían entre 17 y 18 años de edad; 99% eran solteros; 26,3% trabajan y un 45,2% eran de nivel socioeconómico medio alto y alto. Se les aplicó un instrumento auto administrado en línea, basado en: 1,- La versión en español del cuestionario Youth Quality of Life - Research Versión (YQOL-R) con cuatro dominios (general, personal relacional y ambiental) con 65 ítmes de los que se analizó el módulo perceptual (42 ítmes). 2,- Del Youth Risk Behavior Surveillance YRBS 2007, 30 ítems y se agrego 2. 3,- 9 Sociodemográficas además de 9 personales escolares. Se utilizó la estadística descriptiva para la frecuencia de la CV y Cr por variables sociodemográficas. Se probó la normalidad del índice total de CV y la cantidad de Cr aplicando pruebas de normalidad Kolgomorov-Smirnov y Shapiro-Wilk y se utilizó U de Mann Withney y Chi cuadrado para conocer las diferencias en variables sociodemográficas. Para conocer la asociación entre CV y Cr se aplicó p de Spearmn y se buscaron modelos significativos mediante regresión logística multinominal. Como principios éticos se solicitó el consentimiento informado, participación voluntaria y confidencialidad de la información

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
[Quality of life according to self-perceived weight, weight control behaviors, and gender among adolescent university students in Mexico]
No full textUNLABELLED: The aim of this study was to analyze quality of life (QoL) according to self-perceived weight and weight control behaviors, by gender. The sample consisted of 2,401 adolescent students (17-19 years of age) enrolled from 2007 to 2009 at a Mexican university; 61.9% were women, 19.4% worked, and 99.2% were single. An online self-administered questionnaire was used that included the perceptual module of the YQOL-R and seven items on body weight, adapted from YRBS 2007. RESULTS: 52% of women and 31.7% of men were attempting to lose weight. The highest QoL scores were in students who felt they were near the right weight, those who were attempting to maintain the same weight, and those who exercised. Lowest QoL was reported by those who considered themselves overweight, were trying to lose weight, were eating less, were skipping meals, or were using unsupervised dieting, vomiting, or laxatives. In women, QoL differed between those maintaining the same weight, gaining weight, and losing weight, while QoL in men only differed for those attempting to gain weight. The findings could be useful in educational processes, preventive programs, and assessment of interventions
