Changes in compliance with school-based physical activity recommendations in Spanish youth: The UP&DOWN longitudinal study
The study aimed (a) to examine changes in physical activity (PA) during the whole day, school hours, recess, and physical education classes (PEC) during a 2-year period in primary and secondary students; (b) to identify changes in the proportion of compliance with specific PA recommendations for these periods; and (c) to examine whether PA levels at baseline are associated with PA levels 2 years later. Eight hundred and fourteen (51.8% boys) children and 658 (50.1% boys) adolescents from 41 Spanish schools participated in the study. Hip-worn accelerometers were used to assess PA during different time periods. Light PA (LPA) declined during the whole day, school hours, recess (all P < 0.001, except child girls for recess), and PEC (all, P < 0.05) in children and adolescents. Moderate-to-vigorous PA (MVPA) during the whole day and recess declined in child boys (P < 0.01 and P < 0.001, respectively) and adolescent boys (P < 0.001 and P < 0.05, respectively). MVPA during PEC declined in adolescent boys (P < 0.001) and adolescent girls (all P < 0.05). The proportion of compliance with the specific PA recommendations for these periods declined (P < 0.05), except for PEC in adolescent girls. PA during the whole day at baseline was moderately associated with PA during the whole day years later (ICCs = 0.210-0.544, with one exception), but this association was lower for the school-based PA. In conclusion, time spent in MVPA and LPA during the whole day and recess declined over time in child and adolescent boys and during PEC in adolescents. These findings highlight the need to promote PA interventions in these settings
Physical activity, sitting time, and mortality from inflammatory diseases in older adults
Objective: The aim of this study was to examine the independent and combined associations of physical activity (PA) and sitting time (ST) with long-term mortality attributed to inflammatory causes other than cardiovascular disease (CVD) and cancer in a national cohort of older adults in Spain. Design: Prospective study. Setting and Participants: A cohort of 3,677 individuals (1,626 men) aged =60 years was followed-up during 14.3 years. Measures: At baseline, individuals reported PA and ST. The study outcome was death from inflammatory diseases when CVD or cancer mortality was excluded. This outcome was classified into infectious and non-infectious conditions. Analyses were performed with Cox regression and adjusted for PA, ST, and other main confounders (age, sex, educational level, smoking, alcohol consumption, body mass index, and chronic conditions). Results: During follow-up, 286 deaths from inflammatory diseases (77 from infectious diseases) were identified. Compared to individuals who defined themselves as inactive/less active, mortality from inflammatory diseases was lower in those who were moderately active (hazard ratio [HR] = 0.67, 95% confidence interval [CI] = 0.50-0.90) or very active (HR = 0.48, 95%CI = 0.33-0.68), independently of ST. Also, being seated ≥7 h/d vs. < 7 h/d was linked to higher mortality (HR = 1.38, 95%CI = 1.02-1.87). The largest risk of mortality was observed in inactive/less active individuals with ST≥7 h/d (HR = 2.29, 95%CI = 1.59-3.29) compared to those with moderate/very PA and ST < 7 h/d. Low PA and high ST were consistently associated with a higher risk of mortality from non-infectious inflammatory causes. Associations of PA and ST with mortality from infectious inflammatory causes showed a similar trend, but most of them did not reach statistical significance. Conclusions: Low PA and high ST were independently associated with higher mortality from inflammatory diseases other than CVD or cancer in older adults. Interventions addressing simultaneously both behaviors could have greater benefits than those focusing on only one of themThis work was supported by FIS grant 16/609 (Instituto de Salud Carlos III, State Secretary of R+D+I and FEDER/FSE), MINECO R+D+I grant (DEP2013-47786-R), MECD mobility

¿Son el bajo nivel de condición física y la obesidad dos características del adolescente con síndrome de Down?
Introduction: “Obesity” is considered a feature of
youth with DS but whether “low physical fitness” is also a
feature is unknown.
Objective: The aim of this case-control study was to
compare the levels of fatness and fitness in adolescents
with and without DS.
Methods: Participants included 17 (5 girls) adolescents
with DS aged 12-18 years and a control group of 94 (45
girls) adolescents without DS aged 12-16 years. The
ALPHA health-related fitness test battery for children
and adolescents was selected to assess fatness and fitness
in both groups.
Results: There were no differences in levels of fatness
between groups (all P > 0.27). Adolescents with DS had
lower levels of fitness in all the tests than adolescents
without DS (all P < 0.001).
Conclusion: Adolescents with DS have similar levels of
fatness and lower levels of fitness than their peers without
DSIntroducción: La obesidad es considerada una característica
de los jóvenes con SD, sin embargo se desconoce si
la “baja condición física” también lo es.
Objetivo: Comparar los niveles de obesidad y condición
física en adolescentes con y sin SD.
Métodos: Participaron 17 adolescentes (5 niñas) con SD
de 12 a 18 años y un grupo control de 94 (45 niñas) adolescentes
sin SD de 12-16 años de edad. La batería de condición
física ALPHA relacionada con la salud para niños y
adolescentes fue seleccionada para evaluar la obesidad y
la condición física en ambos grupos.
Resultados: No se encontraron diferencias en los niveles
de obesidad entre grupos (P > 0,27). Los adolescentes
con SD tuvieron niveles más bajos de condición física en
todos los test en comparación con los adolescentes sin SD
(P < 0,001).
Conclusión: Los adolescentes con SD tienen niveles
similares de obesidad y menores de condición física que
sus compañeros sin SD.The UP&DOWN study was supported by the
