[EN]: Introduction: the main objectives of weight-loss interventions are to decrease fat mass while maintaining fatfree mass. Objective: our aim was to address effectiveness body composition changes in overweight adolescents assessed by different body composition methods following an obesity intervention programme. Material and methods: the life-style intervention was multi-disciplinary, with 13 months follow-up. Participants were 13-to-16 year-old overweight, or obese, Spanish adolescents. The adolescents (n = 156; 54.8% females) had body composition measured with anthropometry, dual-energy X-ray absorptiometry and air-displacement plethysmography. All measurements were made at baseline, and after 2- and 13-months. Repeated measures analysis of covariance to compare mean anthropometric changes over time and the Bonferroni correction were applied. Imputation of anthropometric measures was performed. Results: a high significant decrease in fat mass index was achieved in males after 2-and 13-months of intervention as measured by anthropometry (1.16 and 1.56 kg / m2, respectively), X-ray absorptiometry (1.51 and 1.91 kg / m2) and plethysmography (2.13 and 2.44 kg/m2). Moreover, a short and long-term maintenance of fat-and fat-free mass index was observed by X-ray absorptiometry in females (0.94 and 0.68 kg/m2). Conclusion: our multidisciplinary approach to lifestyle intervention has a favourable impact on body fat mass and fat-free mass index as well as waist-to-height ratio, over 13 months intervention in overweight and obese adolescents. ; [ES]: Introducción: el principal objetivo de las intervenciones de pérdida de peso es disminuir la masa grasa manteniendo la masa libre de grasa. Objetivo: evaluar la efectividad de una intervención multidisciplinar en la composición corporal de adolescentes con sobrepeso, evaluados mediante diferentes métodos de composición corporal. Material y métodos: la intervención fue multidisciplinar sobre el estilo de vida, aplicada durante 13 meses. Los participantes eran adolescentes entre 13 y 16 años con sobrepeso y obesidad. Los adolescentes (n = 156; 54,8% mujeres) fueron evaluados mediante antropometría, absorciometría dual de rayos X y pletismografía por desplazamiento de aire. Todas las mediciones se realizaron al inicio, a los 2 y a los 13 meses. Se aplicaron análisis de la covarianza de medidas repetidas y la corrección de Bonferroni. Se realizó la imputación de las medidas antropométricas. Resultados: se logró una alta disminución significativa en el índice de masa grasa en los hombres después de 2 y 13 meses de intervención, según antropometría (1,16 y 1,56 kg/m2, respectivamente), absorciometría de rayos X (1,51 y 1,91 kg/m2) y pletismografía (2,13 y 2,44 kg/m2). Por otra parte, el mantenimiento a corto y largo plazo de la grasa y libre de grasa en el índice de masa fue observado por absorciometría de rayos X en las mujeres (0,94 y 0,68 kg/m2). Conclusión: la intervención multidisciplinar sobre estilo de vida tiene un impacto favorable en la masa grasa corporal y el índice de masa libre de grasa, así como en la relación cintura-altura, durante 13 meses de intervención en adolescentes con sobrepeso y obesidad. ; The study was supported by: the Ministry of Health, Social Services and Equality; the Spanish Government (Carlos III Institute of Health.

BACKGROUND: Eggs are a major source of dietary cholesterol and their consumption has been sometimes discouraged. A relationship between egg consumption and the incidence of cardiovascular disease (CVD) has been suggested to be present exclusively among patients with type2 diabetes. AIMS: To assess the association between egg consumption and CVD in a large Mediterranean cohort where approximately 50% of participants had type 2 diabetes. METHODS: We prospectively followed 7216 participants (55-80 years old) at high cardiovascular risk from the PREDIMED (PREvención con DIeta MEDiterránea) study for a mean of 5.8 years. All participants were initially free of CVD. Yearly repeated measurements of dietary information with a validated 137-item food-frequency questionnaire were used to assess egg consumption and other dietary exposures. The endpoint was the rate of major cardiovascular events (myocardial infarction, stroke or death from cardiovascular causes). RESULTS: A major cardiovascular event occurred in 342 participants. Baseline egg consumption was not significantly associated with cardiovascular events in the total population. Non-diabetic participants who ate on average >4 eggs/week had a hazard ratio (HR) of 0.96 (95% confidence interval, 0.33-2.76) in the fully adjusted multivariable model when compared with non-diabetic participants who reported the lowest egg consumption (<2 eggs/week). Among diabetic participants, the HR was 1.33 (0.72-2.46). There was no evidence of interaction by diabetic status. HRs per 500 eggs of cumulative consumption during follow-up were 0.94 (0.66-1.33) in non-diabetics and 1.18 (0.90-1.55) in diabetics. CONCLUSIONS: Low to moderated egg consumption was not associated with an increased CVD risk in diabetic or non-diabetic individuals at high cardiovascular risk.
