Testing of stair climbing point-of-choice prompts in Barcelona at an outdoor set of stairs and scalators on the Montjuïc site

Regular stair climbing has well-documented health dividends, such as increased fitness and strength, weight loss and reduced body fat, improved lipid profiles and reduced risk of osteoporosis. The general absence of barriers to participation makes stair climbing an ideal physical activity (PA) for health promotion. Studies in the US and the UK have consistently shown that interventions to increase the accumulation of lifestyle PA by climbing stairs rather than using the escalators are effective. However, there are no previous in Catalonia. This project tested one message for their ability to prompt travelers on the Montjuïc site to choose the stairs rather than the escalator when climbing up the Monjuïc hill. One standard message, " Take the stairs! 7 minutes of stair climbing a day protects your heart" provided a comparison with previous research done in the UK. Translated into Catalan and Spanish, it was presented on a poster positioned at the point of choice between the stairs and the escalator. The study used a quasi-experimental, interrupted time series design. Travelers, during several and specific hours on two days of the week, were coded for stair or escalator use, gender, age, ethnic status, presence of accompanying children or bags by one observer. Overall, the intervention resulted in a 81% increase in stair climbing. In the follow-up period without messages, stair climbing dropped out to baseline levels. This preliminary study showed a significant effect on stair use. However, caution is needed since results are based on a small sample and, only a low percentage of the sample took the stairs at baseline or the intervention phase . Future research on stair use in Catalonia should focus on using bigger samples, different sites (metro stations, airports, shopping centers, etc) , different messages and techniques to promote stair climbing.

Educación física y promoción de la salud: estrategias de intervención en la escuela

Este trabajo pretende profundizar, desde una perspectiva multidisciplinar, en las posibilidades de estrategias e intervenciones que ofrece la Educación Física en el contexto educativo, concretamente en la educación primaria, y que contribuyen al establecimiento de hábitos saludables en el alumnado y que pueden extenderse más allá del propio alumnado. La identificación de tales intervenciones se ha realizado a partir de una revisión profunda de las bases de datos que recogen las publicaciones de más impacto internacional a través de la Web of Knowledge. Asimismo, se presenta la potencial aplicabilidad de estas prácticas, por compartir algunas de las características que las definen o por ser propuestas ya compartidas, en centros educativos que se han transformado en Comunidades de Aprendizaje

Lifestyles positius i reserva cognitiva : Implicacions cognitives, clíniques i biològiques

La reserva cognitiva és un concepte hipotètic actual que sembla presentar la clau per a fer front al repte de les malalties neurodegeneratives. Aquesta es defineix com aquelles capacitats funcionals del cervell que ajuden a la persona a tolerar un major dany cerebral sense presentar manifestació clínica al respecte. La estreta relació del concepte amb els hàbits positius de les persones (lifestyles) la converteix en una variable independent per a la intervenció, prevenció i promoció de la salut. Els canvis morfològics del cervell i la consolidació de circuits neuronals més robustos i eficients semblen explicar els mecanismes de funcionament de la reserva cognitiva. Aquesta revisió defineix el concepte de reserva cognitiva i els models que l'expliquen, troba formes de mesurar-la i representar-la, i evidencia la seva relació amb els lifestyles positius mitjançant estudis epidemiològics i de neuroimatge, per tal de comprendre millor el concepte i enfocar-lo en una línia futura d'investigació.

A systematic review of Twitter’s hashtags in public health: an example of a globally adopted standard

The objective is to find evidence and make recommendations on the use of Twitter in public health,particularly through the study of hashtags(#). This systematic review shows the use of Twitter in different areas of public health: epidemiological surveillance, health promotion, health protection and disease prevention. Articles on this subject published in indexed journals with impact factor show the importance of conversations to engage the attention of Twitter users by using citations (@ user) and retweets(RT); however, not much importance seems to be given to the use of hashtags(#), which are often assimilated to the concept of keywords. Although tracking recurring hashtagsshould be less expensive than computing Twitter content, the potential of hashtaggeddata has not been properly exploited or recognized over the past years, probably due to the lack of efficient tools.
