A los mejores estudiantes no les gusta la educación física durante la adolescencia ¿Mito o realidad? Los estudios Avena, Afinos y Up&Down

Objective: to examine if those adolescents who dislike physical education classes get better results on academic and cognitive performance than their peers. Methods: participants included 4 226 adolescents from the AVENA, AFINOS and UP&DOWN studies. Physical education enjoyment was assessed with a 7-point Likert scale. Cognitive performance in the AVENA study was assessed using the Spanish version of the SRA Test of Educational Ability. Academic performance in the AFINOS and UP&DOWN studies was assessed through Mathematics and Language grades and the average of both subjects. Results: in the AVENA study we found differences in verbal ability among girls who dislike physical education and their peers (P = 0.033). In the AFINOS study, boys who dislike physical education had higher scores in Language than their peers (P = 0.024). In the UP&DOWN study girls who disliked physical education had higher scores in Language and in the average of Language and Mathematics than their peers (P < 0.001). Conclusion: in the AVENA and AFINOS studies adolescents who disliked physical education had similar results in cognitive and academic performance than their peers, but in the UP&DOWN study girls who disliked physical education showed higher results in academic performance than their peers.Objetivo: conocer si a aquellos adolescentes que no les gusta la educación física obtienen mejores resultados en rendimiento académico y cognitivo que sus compañeros. Métodos: los participantes incluyen 4.226 adolescentes de los estudios AVENA, AFINOS y UP&DOWN. El gusto por la educación física se valoró con una escala Likert de 7 puntos. El rendimiento cognitivo se valoró en el estudio AVENA usando la versión española del SRA Test of Educational Ability. El rendimiento académico se valoró en los estudios AFINOS y UP&DOWN con las notas de Matemáticas, Lengua y la media de Lengua y Matemáticas. Resultados: en el estudio AVENA encontramos diferencias en la habilidad verbal entre las chicas a las que no les gustaba la educación física y sus compañeros (P = 0,033). En el estudio AFINOS los chicos a los que no les gustaba la educación física tenían mejores notas en Lengua que sus compañeros (P = 0,024). En el estudio UP&DOWN las chicas a las que no les gustaba la educación física obtuvieron mejores resultados en Lengua y en la media de Lengua y Matemáticas (P < 0,001). Conclusion: en los estudios AVENA y AFINOS los adolescentes a los que no les gusta la educación física obtuvieron resultados similares a los que sus compañeros, mientras que en el estudio UP&DOWN las chicas a las que no les gustaba la educación física obtuvieron mejores resultados en rendimiento académico que sus compañeros

Birth weight and blood lipid levels in Spanish adolescents: Influence of selected APOE, APOC3 and PPARgamma2 gene polymorphisms. The AVENA Study

Es reproducción del documento publicado en http://dx.doi.org/10.1186/1471-2350-9-98Background: There is increasing evidence indicating that genes involved in certain metabolic processes of cardiovascular diseases may be of particular influence in people with low body weight at birth. We examined whether the apolipoprotein (APO) E, APOC3 and the peroxisome proliferator-activated receptor-gamma-2 (PPAR gamma 2) polymorphisms influence the association between low birth weight and blood lipid levels in healthy adolescents aged 13-18.5 years. Methods: A cross-sectional study of 502 Spanish adolescents born at term was conducted. Total (TC) and high density lipoprotein cholesterol (HDLc), triglycerides (TG), apolipoprotein (apo) A and B, and lipoprotein(a) [ Lp(a)] were measured. Low density lipoprotein cholesterol (LDLc), TC-HDLc, TC/HDLc and apoB/apoA were calculated. Results: Low birth weight was associated with higher levels of TC, LDLc, apoB, Lp(a), TC-HDLc, TC/HDLc and apoB/apoA in males with the APOE epsilon 3 epsilon 4 genotype, whereas in females, it was associated with lower HDLc and higher TG levels. In males with the APOC3 S1/S2 genotype, low birth weight was associated with lower apoA and higher Lp(a), yet this association was not observed in females. There were no associations between low birth weight and blood lipids in any of the PPAR gamma 2 genotypes. Conclusion: The results indicate that low birth weight has a deleterious influence on lipid profile particularly in adolescents with the APOE epsilon 3/epsilon 4 genotype. These findings suggest that intrauterine environment interact with the genetic background affecting the lipid profile in later life.Instituto de Salud Carlos III (FIS PI021830), the Spanish Ministry of Health, FEDER-FSE funds FIS n 00/0015, CSD grants 05/UPB32/0, 109/UPB31/03 and 13/UPB20/04, Ministerio de Educación (AP-2004-2745; EX2007-1124

Increase in cigarette smoking and decrease in the level of physical activity among spanish adolescents. AVENA study

Objetivo: El consumo de tabaco entre los adolescentes así como la disminución de los niveles de práctica de actividad física constituyen un problema de salud pública. El objetivo es conocer la relación existente entre el consumo de tabaco y la práctica de actividad física. Ámbito: Adolescentes españoles escolarizados. Sujetos: 2.859 adolescentes españoles (1.357 hombres, 1.502 mujeres; rango de edad: 13-18,5 años) Intervenciones: Se aplica un cuestionario para conocer el consumo de tabaco y otros cuatro cuestionarios para conocer la práctica de actividad física en diferentes periodos de tiempo. Resultados: Un 40,8% de los adolescentes indicaron no practicar actividad física, mostrándose los varones más activos que las mujeres (p < 0,001). Un 29,9% de los adolescentes indicaron consumir tabaco habitualmente, no existiendo diferencias en función del sexo. Tanto en varones como en mujeres, los adolescentes activos manifiestan un menor consumo de tabaco (P ≤ 0,01). A mayor edad mayor consumo de tabaco y menor práctica de actividad física, tanto en varones como en mujeres (p < 0,001). Conclusiones: Los niveles de práctica de actividad física son bajos, siendo menores aún en el caso de las chicas. El consumo de tabaco muestra relación inversa con la práctica de actividad física, resultando los sujetos más activos físicamente los menos consumidores de tabaco.Objective: Cigarette smoking among adolescents as well as the level of physical activity constitutes a public health care issue. The aim is knowing the relationship between cigarette smoking and practice of physical activity. Setting: Schooled Spanish adolescents Subjects: 2859 Spanish adolescents (1357 boys, 1502 girls; age range: 13-18.5 years). Interventions: A questionnaire is applied to know the level of cigarette smoking and four other questionnaires to know the level of physical activity during different periods. Results: 40.8% of the adolescents stated not doing any physical activity at all, boys being more active than girls (p < 0.001). 29.9% of the adolescents stated usually smoking cigarettes, without differences by gender. Both active boys and girls stated smoking less (P ≤ 0.01). The greater the age, the higher cigarette smoking and the lower the level of physical activity, both in boys and girls (p < 0.001). Conclusions: The level of physical activity is low, being even lower for girls. Cigarette smoking shows a negative relationship with the level of physical activity, the individuals more physically active being those smoking the less.El estudio AVENA ha sido financiado por el Ministerio de Sanidad, fondos FEDER-FSE (FIS nº 00/0015), CSD grants 05/UPB32/0, 109/UPB31/03 y 13/UPB20/04, Ministerio de Educación (AP2002- 2920; AP2003-2128; AP-2004-2745), y grants from Panrico S.A., Madaus S.A., y Procter y Gamble S.A

Individual and Combined Effects of ApoE and MTHFR 677C/T Polymorphisms on Cognitive Performance in Spanish Adolescents: The AVENA Study RID C-7661-2009

Objective To examine the individual and combined associations of ApoE and MTHFR 677C/T polymorphisms with cognitive performance in adolescents. Study design The study comprised 412 Spanish adolescents (13 to 18.5 years of age). Cognitive performance (verbal, numeric and reasoning abilities, and an overall score) was measured by the Spanish-version of the SRA-Test of Educational-Ability. Results We observed no differences in the cognitive performance study variables in adolescents carrying or not carrying the ApoE epsilon 4 variant. Adolescents without the MTHFR 677TT genotype had significantly better cognitive performance than their TT peers. The analysis of the combined effect of these polymorphisms revealed that those individuals carrying both the ApoE epsilon 4 variant and the MTHFR 677TT genotype had significantly worse cognitive performance than their peers with other genotype combinations. These findings were independent of sex, age pubertal status, socioeconomic status, physical activity, and skipping breakfast. Conclusions The results of the present study suggest that the ApoE epsilon 4 alone is not associated with cognitive performance in adolescents. Individuals with the MTHFR 677TT genotype had slightly impaired cognitive performance, whereas we observed a combined effect of both the ApoE epsilon 4 variant and the MTHFR 677TT genotype on cognitive performance. More research is needed in larger population samples to corroborate our findings. (J Pediatr 2010;156:978-84).4.042 JCR (2010) Q1, 3/109 PediatricsUE
