ABSTRACT

Objective:

Adolescent’s ideal cardiovascular health index (ICVH) seems to be an important indicator of youth’s lifestyles and cardiometabolic health with potential positive consequences for their Health-Related Quality of Life (HRQoL). The purpose of this study was to examine the associations between the ICVH index and HRQoL in adolescents.

Methods:

This was a cross-sectional study based on secondary analyses from the LabMed Physical Activity Study (n=407 adolescents, 53% girls). ICVH, as defined by the American Heart Association, was determined as meeting ideal behaviors (physical activity, body mass index, smoking status, and diet intake) and health factors (blood pressure, total glucose, and cholesterol). HRQoL was measured with the Kidscreen-10 self-report questionnaire.

Results:

Analysis of covariance (ANCOVA) showed a significant association between the accumulation of ideal cardiovascular health metrics and HRQoL (F _(4,403)=4.160; p=0.003). In addition, the higher the number of ideal health behaviors accumulated, the higher the mean values of HRQoL (p-value for trend=0.001), after adjustments for age, sex, socioeconomic status and pubertal stage.

Conclusions:

ICVH index was positively associated with HRQoL in adolescents. Ideal health behaviors metrics seem to have a stronger association with HRQoL than the ideal health factors metrics in adolescents.

RESUMO

Objetivo:

O Índice de Saúde Cardiovascular Ideal (ISCI) do adolescente parece ser um importante indicador do estilo de vida e da saúde cardiometabólica dos jovens, com possíveis consequências positivas para a Qualidade de Vida Relacionada à Saúde (QVRS). O objetivo deste estudo foi examinar as associações do ISCI e da QVRS em adolescentes.

Métodos:

Este foi um estudo transversal baseado em análises secundárias do estudo LabMed Physical Activity (n=407 adolescentes, 53% meninas). O ISCI, conforme definido pela American Heart Association , foi determinado como atendendo a comportamentos ideais (atividade física, índice de massa corporal, tabagismo e padrão alimentar) e fatores de saúde (pressão arterial, glicose total e colesterol). A QVRS foi mensurada com o questionário de autorrelato Kidscreen-10.

Resultados:

A análise de covariância mostrou associação entre o acúmulo de métricas ideais de saúde cardiovascular e a QVRS (F _(4,403)=4,160; p=0,003). Quanto maior o número de comportamentos ideais de saúde acumulados, maiores os valores médios da QVRS (p-valor de tendência=0,001), após ajustes para idade, sexo, status socioeconômico e estágio pubertal.

Conclusões:

O índice de saúde cardiovascular ideal associou-se positivamente à QVRS em adolescentes. As métricas ideais de comportamentos de saúde parecem ter uma associação mais forte com a QVRS do que as métricas ideais de fatores de saúde em adolescentes.

Executive Functions

Adele Diamond (2013)

Executive functions (EFs) make possible mentally playing with ideas; taking the time to think before acting; meeting novel, unanticipated challenges; resisting temptations; and staying focused. Core EFs are inhibition [response inhibition (self-control—resisting temptations and resisting acting impulsively) and interference control (selective attention and cognitive inhibition)], working memory, and cognitive flexibility (including creatively thinking “outside the box,” seeing anything from different perspectives, and quickly and flexibly adapting to changed circumstances). The developmental progression and representative measures of each are discussed. Controversies are addressed (e.g., the relation between EFs and fluid intelligence, self-regulation, executive attention, and effortful control, and the relation between working memory and inhibition and attention). The importance of social, emotional, and physical health for cognitive health is discussed because stress, lack of sleep, loneliness, or lack of exercise each impair EFs. That EFs are trainable and can be improved with practice is addressed, including diverse methods tried thus far.

The prevalence of metabolic syndrome in children: a systematic review of the literature.

Amanda Friend, Leone Craig, Steve Turner (2013)

Metabolic syndrome has been identified as a condition of childhood relatively recently. The aim in this study was to describe the prevalence of metabolic syndrome in children allowing for differences in metabolic syndrome definitions. This was a systematic review of the OVID, EMBASE, and CINAHL databases, capturing details of overall prevalence and prevalence within groups categorized by obesity, gender, age, and ethnicity. In all, 378 studies published since 2003 were identified, and of these 85 papers were included in the present review. When all studies were considered, the median prevalence of metabolic syndrome in whole populations was 3.3% (range 0%-19.2%), in overweight children was 11.9% (range 2.8%-29.3%), and in obese populations was 29.2% (range 10%-66%). Within-study analyses confirmed higher prevalence for obese compared to overweight (P=0.012) and obese compared to nonobese, nonoverweight children (P<0.001). Within-study analyses also revealed higher median metabolic syndrome prevalence for boys compared to girls (5.1% versus 3.0%, P<0.001) and also in older compared with younger children (5.6% versus 2.9%, P=0.001). Limited evidence was found to suggest differences between ethnic groups, and there were insufficient studies to determine whether metabolic syndrome prevalence was increasing over time. This is the first systematic review of all of the relevant literature. It describes the magnitude of associations between metabolic syndrome and obesity, age, and gender. We find evidence that ethnicity and geography may be important to metabolic syndrome prevalence in children and these associations require further study.

Ideal cardiovascular health in childhood and cardiometabolic outcomes in adulthood: the Cardiovascular Risk in Young Finns Study.

Mika Kähönen, Costan Magnussen, Mervi Oikonen … (2012)

The American Heart Association (AHA) defined a new concept, cardiovascular health, and determined metrics needed to monitor it over time as part of its 2020 Impact Goal definition. Ideal cardiovascular health is defined by the presence of both ideal health behaviors and ideal health factors. The applicability of this concept to a cohort of children and its relationship with cardiometabolic outcomes in adulthood has not been reported. The sample comprised 856 participants aged 12 to 18 years (mean age 15.0 years) from the Cardiovascular Risk in Young Finns Study cohort. Participants were followed up for 21 years since baseline (1986) and had data available concerning health factors and behaviors in childhood and cardiometabolic outcomes in adulthood (2007). The number of ideal cardiovascular health metrics present in childhood was associated with reduced risk of hypertension (odds ratio [95% confidence interval] 0.66 [0.52-0.85], P<0.001), metabolic syndrome (0.66 [0.52-0.77], P<0.001), high low-density lipoprotein cholesterol (0.66 [0.52-0.85], P=0.001), and high-risk carotid artery intima-media thickness (0.75 [0.60-0.94], P=0.01) in adulthood. All analyses were age and sex adjusted, and the results were not altered after additional adjustment with socioeconomic status. The number of ideal cardiovascular health metrics present in childhood predicts subsequent cardiometabolic health in adulthood. Our findings suggest that pursuit of ideal cardiovascular health in childhood is important to prevent cardiometabolic outcomes in adulthood.
