Influence of cardiorespiratory fitness and parental lifestyle on adolescents' abdominal obesity

The aims of this study were (1) to analyse the influence of cardiorespiratory fitness (CRF) and parental overweight status (POS) and socioeconomic status (SES) on abdominal obesity. This study was comprised of 779 adolescents (12-18 years). Waist-height ratio (WHtR), 20 m shuttle-run test to ascertain CRF, POS according to World Health Organization recommendations and SES of parents using level of education were analysed. Using WHtR, the prevalence of abdominal obesity was 21.3% (23.5% girls and 17.9% boys; p = 0.062). Regardless of gender, participants who belonged to the WHtR risk group had significantly (p ≤ 0.05) lower CRF scores than the WHtR non-risk group; 84.4% of girls who belonged to the WHtR risk group had one or two overweight parents (p ≤ 0.05). Boys with low CRF (OR: 6.43; CI: 3.33-12.39) were more likely to belong to the WHtR risk group compared with their lean peers. Girls with low CRF (OR: 1.78; CI: 1.14-2.78) and with at least one overweight parent (OR: 2.50; CI: 1.07-5.85) or two overweight parents (OR: 4.90; CI: 2.08-11.54) were associated with the risk of abdominal obesity. This study highlights the influence of adolescents' family on abdominal obesity, especially in girls. Further, the data suggested that low CRF was a strong predictor of risk values of abdominal obesity in adolescence.

Relationship of milk intake and physical activity to abdominal obesity among adolescents

Background: Diet and physical activity (PA) are recognized as important factors to prevent abdominal obesity (AO), which is strongly associated with chronic diseases. Some studies have reported an inverse association between milk consumption and AO. Objective: This study examined the association between milk intake, PA and AO in adolescents. Methods: A cross-sectional study was conducted with 1209 adolescents, aged 15–18 from the Azorean Archipelago, Portugal in 2008. AO was defined by a waist circumference at or above the 90th percentile. Adolescent food intake was measured using a semi-quantitative food frequency questionnaire, and milk intake was categorized as ‘low milk intake’ (<2 servings per day) or ‘high milk intake’ ( 2 servings per day). PA was assessed via a self-report questionnaire, and participants were divided into active (>10 points) and low-active groups ( 10 points) on the basis of their reported PA. They were then divided into four smaller groups, according to milk intake and PA: (i) low milk intake/low active; (ii) low milk intake/active; (iii) high milk intake/low active and (iv) high milk intake/active. The association between milk intake, PA and AO was evaluated using logistic regression analysis, and the results were adjusted for demographic, body mass index, pubertal stage and dietary confounders. Results: In this study, the majority of adolescents consumed semi-skimmed or skimmed milk (92.3%). The group of adolescents with high level of milk intake and active had a lower proportion of AO than did other groups (low milk intake/low active: 34.2%; low milk intake/active: 26.9%; high milk intake/low active: 25.7%; high milk intake/active: 21.9%, P = 0.008). After adjusting for confounders, low-active and active adolescents with high levels of milk intake were less likely to have AO, compared with low-active adolescents with low milk intake (high milk intake/low active, odds ratio [OR] = 0.412, 95% confidence intervals [CI]: 0.201– 0.845; high milk intake/active adolescents, OR = 0.445, 95% CI: 0.235–0.845).Conclusion: High milk intake seems to have a protective effect on AO, regardless of PA level

Association between dairy product intake and abdominal obesity in Azorean adolescents

BACKGROUND: Some studies have reported an inverse association between dairy product (DP) consumption and weight or fat mass loss. OBJECTIVES: The objective of our study was to assess the association between DP intake and abdominal obesity (AO) among Azorean adolescents. SUBJECTS/METHODS: This study was a cross-sectional analysis. A total of 903 adolescents (370 boys) aged 15--16 years was evaluated. Anthropometric measurements were collected (weight, height and waist circumference (WC)) and McCarthy’s cut-points were used to categorize WC. AO was defined when WC was X90th percentile. Adolescent food intake was assessed using a self-administered semiquantitative food frequency questionnaire and DP intake was categorized in o2 and X2 servings/day. Data were analyzed separately for girls and boys, and logistical regression was used to estimate the association between DPs and AO adjusting for potential confounders. RESULTS: The prevalence of AO was 54.9% (boys: 32.1% and girls: 70.7%, Po0.001). For boys and girls, DP consumption was 2.3±1.9 and 2.1±1.6 servings/day (P¼0.185), respectively. In both genders, the proportion of adolescents with WC o90th percentile was higher among individuals who reported a dairy intake of X2 servings/day compared with those with an intake o2 servings/day (boys: 71% vs 65% and girls: 36% vs 24%, Po0.05). After adjustments for confounders, two or more DP servings per day were a negative predictor of AO (odds ratio, 0.217; 95% confidence interval, 0.075 -- 0.633) only in boys. CONCLUSION: We found a protective association between DP intake and AO only in boys.

Tornar-se adulto na Casa 5: promover a autonomia individual em Apartamento de Autonomização

Na ausência de uma retaguarda familiar capaz de se constituir como uma rede de segurança e apoio ao desenvolvimento integral de adolescentes com medida de promoção e proteção, o Apartamento de Autonomização oferece um espaço no qual os jovens podem treinar competências que lhes assegurem um futuro autónomo e minimizem os riscos de exclusão social. Esta resposta social propõe-se preparar adolescentes, em transição para a adultez juvenil, para a conquista da responsabilidade de se autoprotegerem, de cuidarem de si próprios e de assumirem a sua identidade perante os outros. Todavia, um projeto de Autonomização de Vida revela-se um desafio, não apenas para os jovens, como também para as famílias e para os profissionais que com eles trabalham. Foram, precisamente, as dificuldades inerentes à Autonomização de Vida em contexto institucional que motivaram o desenvolvimento de um projeto em educação e intervenção social promotor da eficiência dessa resposta social em termos de promoção da autonomia e da transição bem-sucedida para a vida adulta. O presente relatório constitui, assim, um olhar retrospetivo sobre o Projeto “Tornar-se Adulto na Casa 5”, o qual, através da metodologia de Investigação-Ação Participativa, visou alcançar a finalidade proposta pelos participantes: “Promover uma autonomia plena dos jovens da Casa 5, com vista à transição bem-sucedida para a vida adulta após o término da medida de promoção e proteção”. Ainda que os resultados obtidos tenham sido moderadamente satisfatórios, o Projeto terá contribuído para o desenvolvimento de uma consciencialização mais crítica acerca das oportunidades e dos constrangimentos ao desenvolvimento da Autonomia, favorecendo, desejavelmente, a transição para vida adulta após a desinstitucionalização.

Motivação de crianças e jovens para a prática vocal

Este relatório foi escrito no âmbito do estágio de Prática Educativa do Mestrado em Ensino da Educação Musical no Ensino Básico da Escola Superior de Educação do Instituto Politécnico do Porto. No primeiro capítulo encontra-se a caracterização dos contextos onde decorreu a Prática Educativa – escolas, turmas e comunidades educativas. O segundo capítulo engloba a reflexão e fundamentação das opções realizadas ao longo das três Práticas Educativas, que resultaram da negociação entre os ideais, os programas e as crianças e os jovens envolvidos, suas competências, anseios e motivações. O terceiro capítulo é dedicado ao projeto de investigação realizado sobre a motivação de crianças e jovens dos 2º e 3º ciclos do ensino básico para participarem em atividades de prática vocal extracurriculares e suas implicações para a Educação Musical na sala de aula. O contraste entre a motivação dos alunos na sala de aula e em atividades extracurriculares suscitou o desenvolvimento deste estudo em dois contextos: o Coro dos Meninos Cantores do Município da Trofa e o Clube de Canto da Escola Básica Augusto Gil. A reflexão sobre a Prática Educativa é um instrumento ao serviço dos professores que lhes permite avaliar, e avaliarem-se, e introduzir mais consciência e reflexividade na sua acção, com vista a melhorá-la continuamente e a torná-la pertinente para o percurso dos seus alunos num mundo em constante mudança.
