Do socioeconomic factors shape weight and obesity trajectories over the transition from midlife to old age? Results from the French GAZEL cohort study

BACKGROUND: Obesity is a contemporary epidemic that does not affect all age groups and sections of society equally. OBJECTIVE: The objective was to examine socioeconomic differences in trajectories of body mass index (BMI; in kg/m(2)) and obesity between the ages of 45 and 65 y. DESIGN: A total of 13,297 men and 4532 women from the French GAZEL (Gaz de France Electricité de France) cohort study reported their height in 1990 and their weight annually over the subsequent 18 y. Changes in BMI and obesity between ages 45 and 49 y, 50 and 54 y, 55 and 59 y, and 60 and 65 y as a function of education and occupational position (at age 35 y) were modeled by using linear mixed models and generalized estimating equations. RESULTS: BMI and obesity rates increased between the ages of 45 and 65 y. In men, BMI was higher in unskilled workers than in managers at age 45 y; this difference in BMI increased from 0.82 (95% CI: 0.66, 0.99) at 45 y to 1.06 (95% CI: 0.85, 1.27) at 65 y. Men with a primary school education compared with those with a high school degree at age 45 y had a 0.75 (95% CI: 0.51, 1.00) higher BMI, and this difference increased to 1.32 (95% CI: 1.03,1.62) at age 65 y. Obesity rates were 3.35% and 7.68% at age 45 y and 9.52% and 18.10% at age 65 y in managers and unskilled workers, respectively; the difference in obesity increased by 4.25% (95% CI: 1.87, 6.52). A similar trend was observed in women. Conclusions: Weight continues to increase in the transition between midlife and old age; this increase is greater in lower socioeconomic groups.

Pràcticum I : Psicologia de l'Educació. Anàlisi de l'educació inclusiva a través d'una aula USEE a secundària

L'existència d'una aula USEE ha de permetre la inclusió dels alumnes amb NEE en un entorn majoritàriament ordinari. El present treball és una aproximació a l'educació inclusiva, les seves dificultats i aplicacions a través d'una experiència pràctica en un institut al voltant de la seva aula USEE. Les tasques pràctiques realitzades estan dividides en dos grans blocs: per una banda la recollida d'informació per a la identificació i l'anàlisi dels grau d'inclusió dels alumnes i del funcionament general del centre i per altra banda, una intervenció a la pròpia aula USEE a través d'un taller de ceràmica, el qual em va permetre valorar el sentiment de pertinença dels alumnes i treballar amb ells temes com l'autoconcepte, l'aprenentatge constructiu, les habilitats socials i les estratègies d'aprenentatge. He pogut constatar com una USEE és un recurs facilitador del model inclusiu si es donen algunes condicions fonamentals com aquelles que afecten a la cultura de centre. Finalment, el treball aporta algunes idees per orientar el centre cap a una millora en la seva cultura inclusiva.

Performance in post-compulsory education: evidence from vocational and academic tracks

This paper investigates the factors in_uencing grade performance in two different high school tracks (academic and vocational), including the effect of the amount of work achieved while studying. The empirical strategy analyzes grade progression through the outcomes, passing, repeating and dropping out, conditioning on previous outcomes, and dealing with the endogeneity introduced by the working variable. The analysis is based on a unique Spanish data with information on schooling and labor histories. Findings show that working reduces performance in both tracks, mainly during the first year, although the ffects are less detri- mental in the vocational path. Additionally, good performance in compulsory education, at- tending a private high school, or having high-educated parents improve outcomes, particularly in academic high school.

La psychologie d'Aristote chez Freud : essai de psychologie comparée

VEsquisse (1895) ainsi que le chapitre VII de L'interprétation du rêve (1900) de Freud offrent un modèle psychologique - sous-jacent à toute la psychanalyse élaborée par la suite - qui présente des analogies frap¬pantes avec les conceptions aristotéliciennes sur la psyché, principalement développées dans le De l'âme et les Petits traités d'histoire naturelle. Ceci peut se comprendre entre autres par le fait que les seuls cours uni¬versitaires de psychologie et de philosophie que Freud fréquenta, parallèlement à ses études de médecine, furent ceux du théologien, psychologue et philosophe Franz Brentano, grand spécialiste d'Aristote, dont l'impact de l'enseignement sur le jeune Freud est aujourd'hui mieux connu grâce à son échange épistolaire, au début de ses études, avec son ancien ami de gymnase Eduard Silberstein. En effet, plus d'un élément du paradigme psychologique aristotélicien, qui chez cet auteur s'ancre dans la biologie, semblent trouver écho chez Freud : ainsi, la génération de diverses sortes de représentation au sein de l'appareil psychique par l'investissement des traces mnésiques, chez Freud, fait penser à la production ât phantâsmata dans l'âme, par le travail de la phantasîa sur les mouvements résiduels de la perception sensorielle, chez Aristote. De là, ce sont autant le fonctionnement mnésique, que l'explication des phénomènes du rêve et de l'hallucination, que la compréhension du désir dans sa capacité de mettre en mouvement le vivant animé (c'est-à-dire un être doté d'une âme) qui vont représenter les points d'articulation de cette comparaison. -- The Project for a Scientific Psychology (1895) as well as Chapter VII of Freud's Interpretation of Dreams (1900) offer a psychological model - underlying the entire psychoanalysis developed hereafter - which is strikingly similar to Aristotelian conceptions of the psyche in On the Soul and Little Physical Treatises. One explanation may be that the only lectures in psychology and philosophy that Freud attended at university, alongside lectures in medicine, were given by the theologist, psychologist, and philosopher Franz Brentano, who had a deep knowledge of Aristotle. Because of young Freud's correspondence with his high school friend Eduard Silberstein at the beginning of his studies, the influence of Brentano's teachings on Freud is now better known. Indeed, much of the Aristotelian psychological paradigm - rooted in biology - seems to echo in Freud's writings. Thus, the production of various sorts of representations within the psychic apparatus by means of the investment in memory traces in Freud's model evokes the phantâsmata generated in the soul by the action of phantasîa on the residual movements of the sensory perception in Aristotle's psychology. From there, this comparison will hinge as much on the operation of memory as on the explanation of the phenomena of dreams and hallucinations, as on the understanding of desire in its ability to set the animated living being (i.e. a being with a soul) in motion.

Prevención de la transmisión sexual del VIH en adolescentes

En una muestra de 119 estudiantes de cuarto de Educación Secundaria Obligatoria (ESO) y primerode Bachillerato (52,6% mujeres) se analizan los conocimientos sobre la prevención de latransmisión sexual del virus del sida, las expectativas de resultados y de autoeficacia respecto a losmétodos preventivos y el tipo de prevención utilizada durante la última relación sexual. Para evitarlas respuestas inducidas respecto a los comportamientos preventivos se emplea un formato de preguntaabierta. Los resultados muestran que sólo el 23,5% de los estudiantes han dado dos respuestastotalmente correctas sobre estrategias consideradas eficaces en la prevención sexual del VIH:uso del preservativo y abstinencia (por este orden). El 70,5% valoran totalmente o muy eficaz elpreservativo para evitar la transmisión sexual del VIH y el 95% de los que dan la segunda respuestajuzgan totalmente eficaz la práctica de la abstinencia con la misma finalidad. En el caso del preservativose sienten totalmente o muy capaces de usarlo el 64,3%, mientras que cuando se trata de laabstinencia sólo se perciben con esa competencia el 20%. Por lo que se refiere al uso autoinformadode métodos preventivos en la última relación, por parte de los 29 estudiantes que tuvieronactividad sexual durante el mes anterior, se observa que 21 de ellos emplearon el preservativo, dosla píldora anticonceptiva, otros dos no precisan el tipo de precaución y el resto no tomó ninguna.Tanto el reducido nivel de conocimientos sobre prevención, como la baja percepción de autoeficaciapara mantenerse abstinentes, nos alertan sobre la necesidad de hacer un mayor esfuerzo de informaciónpara eliminar creencias equivocadas, como por ejemplo: sobre la pretendida eficacia protectorade tener relaciones sexuales con una pareja estable o conocida. Así mismo, conviene insistiren el uso del preservativo como anticonceptivo de elección entre los adolescentes

Discovering the campus together: a mobile and computer-based learning experience

One of the most relevant difficulties faced by first-year undergraduate students is to settle into the educational environment of universities. This paper presents a case study that proposes a computer-assisted collaborative experience designed to help students in their transition from high school to university. This is done by facilitating their first contact with the campus and its services, the university community, methodologies and activities. The experience combines individual and collaborative activities, conducted in and out of the classroom, structured following the Jigsaw Collaborative Learning Flow Pattern. A specific environment including portable technologies with network and computer applications has been developed to support and facilitate the orchestration of a flow of learning activities into a single integrated learning setting. The result is a Computer-Supported Collaborative Blended Learning scenario, which has been evaluated with first-year university students of the degrees of Software and Audiovisual Engineering within the subject Introduction to Information and Communications Technologies. The findings reveal that the scenario improves significantly students’ interest in their studies and their understanding about the campus and services provided. The environment is also an innovative approach to successfully support the heterogeneous activities conducted by both teachers and students during the scenario. This paper introduces the goals and context of the case study, describes how the technology was employed to conduct the learning scenario, the evaluation methods and the main results of the experience.

Smoking and adolescence: Exploring tobacco consumption and related attitudes in three different age groups in Switzerland

The present study constitutes an investigation of tobacco consumption, related attitudes and individual differences in smoking or non-smoking behaviors in a sample of adolescents of different ages in the French-speaking part of Switzerland. We investigated three school-age groups (7th-grade, 9th-grade, and the second-year of high school) for differences in attitude and social and cognitive dimensions. We present both descriptive and inferential statistics. On an inferential level, we present a binary logistic regression-based model predicting risk of smoking. The resulting model most importantly suggests a strong relationship between smoking and alcohol consumption (both regular and sporadic). We interpret this result in terms of both the impact of the actual campaigns and the cognitive processes associated with adolescence.
