RESUMEN
Introducción: el sobrepeso y la obesidad infantil han aumentado progresivamente en las últimas décadas, especialmente en países del sur de Europa. Objetivo: analizar la asociación del sobrepeso y la obesidad infantil en la ciudad de Barcelona según variables socioeconómicas en escolares de tercero de Primaria. Métodos: estudio transversal. Población de estudio: alumnos de tercero de Primaria de la ciudad de Barcelona en el año 2011 (n = 3.624). Como variable dependiente se estudió el índice de masa corporal y como independientes: sexo, edad, clase social, situación parental, procedencia, titularidad de la escuela, nivel socioeconómico del barrio de la escuela y distrito. Se realizaron modelos de regresión logística, obteniendo odds ratio (OR) con sus intervalos de confianza al 95% (IC 95%). Resultados: la prevalencia de sobrepeso y obesidad infantil fue del 24,5% y 13,8%, respectivamente. Las variables asociadas a la obesidad fueron: ser niño (OR = 1,26; IC 95% = 1,02-1,57), de nivel socioeconómico bajo (OR = 1,60; IC 95% = 1,16-2,20), en situación familiar monoparental (OR = 1,35; IC 95% = 1,03-1,77), ser inmigrante (OR = 1,68; IC 95% = 1,33-2,13) y residir en uno de los distritos menos favorecidos de Barcelona. Conclusiones: se evidencia que la clase social, la procedencia, la situación familiar y el distrito de residencia juegan un papel importante en la obesidad infantil
Introduction: childhood overweight and obesity have increased progressively in the last decades, especially in countries of Southern Europe. Objective: to analyze the association of overweight and obesity childhood in the city of Barcelona according to socioeconomic variables in schoolchildren in third grade primary school. Methods: transversal study. Study population: third grade primary school students in the city of Barcelona in year 2011 (n = 3,624). Body mass index was studied as the dependent variable, and sex, age, social class, parental status, origin, ownership school, neighborhood socioeconomic status of the school and district were studied as independent. Logistic regression models were analyzed, obtaining odds ratio (OR) with 95% confidence intervals (95% CI). Results: the prevalence of overweight and obesity in childhood were 24.5% and 13.8%, respectively. The variables associated with obesity were: boy (OR = 1.26; 95% CI = 1.02-1.57), low socioeconomic status (OR = 1.60; 95% CI = 1.16-2.20), single-parent family (OR = 1.35; 95% CI = 1.03-1.77), immigrant (OR = 1.68; 95% CI = 1.33-2.13) and living in one of the less favored districts of Barcelona. Conclusions: it is evident that social class, origin, family status and the district of residence play an important role in childhood obesity

OBJECTIVE: Childhood overweight and obesity have increased progressively in the last decades, especially in countries of Southern Europe. The aim of this study was to identify the prevalence of overweight, obesity and its determinants in schoolchildren between 8-9 years old from Barcelona. METHODS: Cross-sectional study of a representative sample of 3,262 schoolchildren in 2011. Body Mass Index (BMI) was calculated following the criteria established by the World Health Organization (z-scores). Variables on eating behaviour, physical activity and use of new technologies were studied through 2 questionnaires. Logistic regression models were adjusted, obtaining adjusted odds ratio and their confidence intervals (95%). RESULTS: The prevalence of overweight was 24.0% and 12.7% for obesity. Obesity was significantly higher in boys than in girls (14.8% vs 10.8%.). No statistically significant differences were observed in the compliance of recommendations of physical activity practice and use of new technologies according to BMI. Factors associated with obesity in boys were to attend a school located in a neighbourhood of disadvantaged socio-economic status [ORa=1.88 (1.35-2.63)], to belong to an immigrant family [ORa=1.57 (1.12-2.20)], to do not eat at school [ORa=1.76 (1.20-2.59)] and to have some meal alone [ORa=1.95 (1.27-3.00)]. In girls associated factors were to belong to a single-parent family [ORa=1.58 (1.06-2.34)] and to an immigrant family [ORa=1.53 (1.07-2.18)]. CONCLUSIONS: The prevalence of childhood obesity in Barcelona is high. It is more common in boys, being the social determinants most relevant associated factors.

Fundamentos: El sobrepeso y la obesidad infantil han aumentado progresivamente en las últimas décadas, especialmente en países del sur de Europa. El objetivo del estudio fue identificar la prevalencia de sobrepeso, obesidad y sus determinantes en escolares de 8-9 años de Barcelona. Métodos: Estudio transversal descriptivo de una muestra representativa de 3.262 escolares en 2011. Se calculó el Índice de Masa Corporal (IMC) siguiendo los criterios establecidos por la Organización Mundial de la Salud (z-scores). Se estudiaron variables sobre conducta alimentaria, actividad física y uso de nuevas tecnologías mediante 2 cuestionarios. Se ajustaron modelos de regresión logística, obteniendo odds ratio ajustadas e intervalos de confianza (95%). Resultados: La prevalencia de sobrepeso fue del 24,0% y de obesidad del 12,7%. La obesidad fue significativamente mayor en niños que en niñas (14,8% vs. 10,8%). No se observaron diferencias estadísticamente significativas según IMC en el cumplimiento de las recomendaciones de práctica de actividad física ni uso de nuevas tecnologías. Los factores asociados a la obesidad en niños fueron asistir a escuela situada en barrios de nivel socioeconómico desfavorable [ORa=1,88 (1,35-2,63)], pertenecer a familia inmigrante [ORa=1,57 (1,12- 2,20)], no comer en el colegio [ORa=1,76 (1,20-2,59)] y hacer alguna comida solo [ORa=1,95 (1,27-3,00)]. En niñas fueron pertenecer a familia monoparental [ORa=1,58 (1,06-2,34)] y familia inmigrante [ORa=1,53 (1,07-2,18)]. Conclusiones: La prevalencia de obesidad infantil en Barcelona es alta. Es más frecuente en niños, siendo los determinantes sociales los factores asociados de mayor relevancia (AU)

Introducción: Con frecuencia los efectos positivos observados de las intervenciones preventivas escolares son menores a los esperados, habitualmente por una implementación inadecuada. Objetivos: Describir la evaluación de proceso del programa de prevención del consumo de cánnabis en escolares (xkpts.com), medir la satisfacción de los profesores con el programa y definir los parámetros cuantitativos y cualitativos para valorar la exhaustividad de la intervención. Metodología: Estudio descriptivo transversal. Muestra: 117 aulas de 39 escuelas de 3º ESO (2812 escolares). La información se recogió mediante fichas de evaluación cumplimentadas por el profesorado y las familias. Se realizó un análisis descriptivo de la implementación de la intervención en las aulas y de la participación de las familias. Resultados: Tasa de respuesta de los profesores del 65%. La discusión fue la técnica más aplicada (100% de las aulas) y el DVD el recurso más utilizado (93,4%). El entrenamiento de habilidades se aplicó en el 72,4%de aulas. El 59,2% de aulas realizó una intervención aceptable (mínimo 8 de 16 actividades preventivas) frente al 38,2% de aulas con intervención cualificada (mínimo 1 actividad por cada sesión general y 2 por cada específica). La puntuación media de la valoración del programa fue 7,4 y el 81,6% del profesorado volvería a aplicarlo. La tasa de participación de las familias fue del 28,3% (796). Conclusiones: En dos de cada tres aulas la intervención fue aceptable y cuatro de cada diez cumplieron estrictamente el protocolo. Una mayor participación de las familias se corresponde con las escuelas con una mejor implementación de la intervención (AU)
Background: The observed positive effects of school-based prevention programs are frequently lower than what was expected, usually due to inadequate implementation. Aims: To describe the process evaluation of a cannabis use school-based prevention program (xkpts.com), to measure teachers satisfaction with the program and to define quantitative and qualitative parameters for assessing the exhaustiveness of the intervention. Methods: Cross-sectional descriptive study. Sample: 117 9th-gradeclasses in 39 schools (2812 students). The information was gathered by means of a self-report questionnaire for teachers and families. A descriptive analysis was made of the implementation of the intervention in the classrooms and of the families participation. Results: Teachers response rate was 65%. Discussion was the method most widely applied (100% of the classrooms) and DVD was the most widely used material (93.4%). Skills training was applied in 72.4% of the classrooms. In 59.2% of the classrooms there was an acceptable intervention (at least 8 of the 16 preventive activities), while in 38.2% there was a qualified intervention (at least 1 activity for each general lesson and 2 for each specific one). Mean score given to the program by teachers was 7.4, and 81.6% of them reported their intention to apply it again. Participation rate of the students families was 28.3% (796). Conclusions: The intervention was acceptable in two out of three classrooms, while in four out of ten the protocol was applied strictly. Greater participation of the students families corresponded to those schools in which the intervention was better implemented (AU)

Smoking onset takes place in the early years of adolescence, and can be seen as a progression through stages of preparation, trying, experimentation, regular smoking and nicotine dependence or addiction. The objective of this study is to identify 1-year predictors of smoking consolidation among occasional smokers (experimenters) and of cessation among all smokers. A questionnaire developed to monitor trends in smoking and other health-related behaviors was administered in the spring of 1992 and again 1 year later (1993). The survey was carried out in six large, private schools in Barcelona and Raimat, in the Lleida province, in Catalonia (Spain). In total, 1460 schoolchildren aged 12-19 responded to both the baseline and follow-up questionnaires; 1236 questionnaires (84.7%) were matched through a personal code and were used for the longitudinal study. At the baseline survey 28% of the schoolchildren were regular smokers and 17.1 % were occasional smokers, with no differences by gender. At the follow-up survey, progression from occasional to regular smoking was observed in 42% of the girls and 22.7% of the boys. Other predictors of consolidation included drinking alcohol (OR = 3.1; 95% CI = 1.1-10.1) and reporting the intention to smoke in the future (OR = 2.5; 95% CI = 1.3-4.9). Among all the smokers at the baseline, predictors of cessation were smoking occasionally (versus regularly) (OR = 4.9; 95% CI = 2.8-8.6), negative attitudes regarding smoking (OR = 3.3; 95% CI = 1.9-5.4), reporting no intention to smoke in the future (OR = 2.2; 95% CI = 1.3-3.8), gender (OR for boys = 2.1; 95% CI = 1.2-3.6), receiving weekly pocket less than 1000 ptas (OR = 1.7; 95% CI = 1.1-5.3) and age (OR for being 15 and younger = 1.6; 95% CI = 1.1-4.9). We conclude that consolidation of smoking is twice as likely among girls than among boys. Intention to smoke seems to be a good predictor of future behavior, while attitudes may predict cessation, but not consolidation. Available pocket money seems to be a strong risk factor for smoking at this age.
