Adolescence is a critical stage of development and has an important influence on energy balance-related behaviours (EBRBs). When adolescents are associated with obesity it can lead to increased cardiometabolic risk. Here we assess if EBRBs adopted by adolescents included in a subsample are associated with markers of total and abdominal adiposity in a multicentre European study, Healthy Lifestyle in Europe by Nutrition in Adolescence (HELENA-CSS) and a Brazilian study, Brazilian Cardiovascular Adolescent Health (BRACAH study), and whether sleep duration influence the association between skipping breakfast, physical activity and sedentary behaviours, with total and abdominal obesity (AO). Multilevel linear regression models using fixed and random intercepts were used to analyse the association between markers of obesity and EBRBs. Skipping breakfast was the prevalent behaviour in association with obesity among European and Brazilian boys besides European girls, even after stratification by sleep time. Moreover, European boys who slept properly and skipped breakfast had an increased waist circumference (WC), while body mass index (BMI) increased in Brazilian boys. Among Brazilian boys less sleep was protective for total obesity (β = −0.93 kg/m 2 ; 95% CI: −1.80; −0.07). European girls when they were more sedentary, showed an increase in WC, especially for those who reported they slept adequately. Skipping breakfast was associated with total and AO in adolescents independent of sleep duration.

Obesity prevalence has increased worldwide over the last decades and has reached alarming rates in low middleincome countries. Childhood has been affected by this epidemic, leading to premature dramatic health problems. Adipose tissue is currently considered as an endocrine organ modulating an inflammatory state and important metabolic processes (insulin resistance, hypertension, glucose intolerance) leading to consequences of the cardiovascular system. This situation may be worst if the excess of body fat distribution such as abdominal obesity (AO) is involved because it is associated with a more atherogenic risk profile determining the cardiometabolic risks mainly in children and adolescents. Hence, the knowledge regarding the association between AO and cardiometabolic factors aims to prevent and treat the obesity in this young population, avoiding early harmful consequences of adulthood health.

Our multiple indicator questionnaires focused on environmental factors and SES in pediatric health surveys provided useful and easily applicable additional indicators to measure these important determinants of cardiovascular health.

Objective: This study aimed to test the validity of an automatic oscillometric device to measure the blood pressure (BP) in children (n 5 191) and adolescents (n 5 127) aged 3 to 18 years. Methods: Systolic BP (SBP) and diastolic BP (DBP) levels were measured simultaneous by automatic device and mercury column with Y-connection. To verify the validity, Bland-Altman plots and limits of agreement of 95% (95% LOA), specificity and sensitivity of the device, and the grade of British Hypertension Society (BHS) criteria were used.Results: The monitor measurements demonstrated lower measurement bias (mean difference [95% LOA]): 1.4 (29.9 to 12.8) mmHg in children and 4.3 (27.8 to 16.5) mmHg in adolescents for SBP. For DBP, it was 2.2 (27.4 to 11.7) mmHg in children and 1.4 (28.4 to 11.1) mmHg in adolescents. The sensitivity in children was 21.4 (95% CI 5 16.3-26.6), and in adolescents, it was 20.0 (95% CI 5 13.2-26.8); the specificity was 95.9 (95% CI 5 93.4-98.4) in children and 100.0 (95% CI 5 100.0-100.0) in adolescents. The monitor-tested ratings are Grade B for SBP in children and SBP and DBP in adolescents and Grade C for DBP in children. Conclusions: The automatic monitor presented high values of specificity and lower values of sensitivity to the diagnosis of HBP; however, it can be considered accurate (lower measurement bias) and valid for epidemiological and clinical practice in accordance with BHS criteria.

Abstracts / Rev Andal Med Deporte. 2015;8(1):20-47 29 self-rated fitness (SRF) as predictors of all-cause mortality. Moreover, we also examined whether any protective effect of SRH on premature mortality was mediated by SRPA, SRF.Methods. SRH, SRPA and SRF were self-reported in 7111 participants, aged 16 to 96 years, by asking their perceptions of health, PA and fitness, respectively, in comparison with their age peers. Based on their ratings participants were categorised in 3 incremental groups. Cox proportional hazards regression was used to examine associations between SRH, SRPA, SRF and all-cause mortality.Results. During a median follow-up of 23 years, 1850 deaths occurred. SRH, SRPA and SRF were inversely and independently associated with mortality (P < 0.05) after adjustment for sex, age, socio-economic and marital status, body mass index, baseline medical conditions, parental history of chronic disease, fruit, vegetable and alcohol intake, and smoking habits. The association between SRH and mortality remained significant following additional adjustment for SRPA, SRF. Self-rated factors combined were associated with a more than 50% reduced hazard for premature mortality when comparing extreme categories.Conclusion. SRH, SRPA and SRF are independent predictors of mortality. Perceptions of health, physical activity and fitness may be valuable additional tools in epidemiological studies, health surveillance and the clinical setting.http://dx.
