Physical Activity Level, Anthropometric and Cardiovascular Profile Among Students in Sergipe State Attending Public Schools

Abstract Background Cardiovascular diseases are the leading cause of mortality among adults. Evidence has shown that sedentary behaviors are the main preventable outcome, however, many sedentary children also become sedentary adults. Therefore, identifying potential risk factors as early as possible contributes to therapeutic success. Objective To achieve an anthropometric and cardiovascular mapping of school-age students from Sergipe State, Brazil. Methods A school-based cross-sectional study with a representative sample from public schools in the state of Sergipe (n= 4700). Anthropometric and blood pressure measurements were performed, and the Global School-based Student Health Survey was used to assess the physical activity level. An independent samples t-test was performed for all comparisons, and significance was established at 5% (p<0.05). Results Despite showing mean blood pressure values within reasonable limits (SBP = 114.1±12.4 mm Hg and DBP = 66.3±8.1 mm Hg), school-age students did not comply with global recommendations for health promotion. It was also observed a high rate of low body weight (42.6%), suggesting dietary compromises, which can interfere with the development of this population. In addition, only 7.3% of students met the minimum physical activity criteria proposed for maintaining their health status. Conclusion The findings of the present study emphasize the importance of maintaining Physical Education classes as an essential curricular component, since they provide several health benefits and ensure that this population reaches the minimum daily recommendations, preventing diseases in adult life.

Hair cortisol in relation to acute and post-traumatic stress symptoms in children and adolescents.

BACKGROUND: We report on the preliminary results of two independent studies that (1) compare the hair cortisol concentrations (HCC) of healthy controls with patients displaying post-traumatic stress symptoms (PTSS, study 1+2), (2) investigate whether pre-trauma HCC are predictive for the development of acute stress symptoms (ASS) and PTSS (study 1) and (3) determine whether HCC correlate with PTSS in a clinical sample of children (study 2). METHODS: In study 1, the clinical symptoms of 35 minors were examined one (T1) and seven weeks (T2) after surgery following an accident. Hair samples were taken after the accident that reflect cortisol secretion over the past three months before the accident (healthy controls). In study 2, HCC and PTSS symptoms were cross-sectionally assessed in 22 minors who had experienced a psychological trauma. RESULTS: The HCC of patients with PTSS were lower than the HCC of healthy controls (study 1+2). Secondary analyses showed that HCC were significantly lower in male PTSS patients than in male healthy controls, whereas the HCC in females were comparably low in both groups. Pre-trauma HCC did not predict the total ASS and PTSS scores (study 1) and HCC were not directly related to the total PTSS scores (study 2).

Electronic media use and insomnia complaints in German adolescents: gender differences in use patterns and sleep problems.

Electronic media play an important role in the everyday lives of children and adolescents and have been shown to be associated with sleep problems. The objective of this study was to assess the associations between time spent using different electronic media and insomnia complaints (IC) in German adolescents with particular respect to gender differences in use patterns and associations with IC. Cross-sectional data of a weighted total of 7533 adolescents aged 11-17 stem from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS study) that was conducted from 2003 to 2006. The assessment of IC and time spent using different electronic media (television, computer/internet, video games, total screen time, mobile phones, and music) was included in a self-report questionnaire. Binary logistic regression analyses were performed to assess associations between time spent per day with each electronic media and IC. Age, SES, emotional problems (anxiety/depression) and presence of a medical condition were considered as covariates in the adjusted model. Boys and girls were considered separately. For boys: computer/internet use of ≥3 h/d (AOR = 2.56, p < 0.05) and total screen time of ≥8 h/d (AOR = 2.45, p < 0.01) were associated with IC in users. Playing video games for 0.5-2 h/d reduced the odds for IC (AOR = 0.60, p < 0.05) compared to nonusers. For girls: Listening to music for ≥3 h/d was associated with IC (AOR = 4.24, p < 0.05) compared to non-listeners. Everyday use of electronic media devices is associated with IC in adolescents. Clinicians dealing with adolescents referred for sleep problems should be aware of gender-specific patterns of media use and sleep problems.

Correlación entre la resistencia a la insulina y T3 en adolescentes con factores de riesgo para el desarrollo de diabetes / Correlation between insulin resistance and T3 in adolescents with risk factors for developing diabetes

Objetivo. Establecer la correlación entre las concentraciones séricas de triyodotironina y la resistencia a la insulina a través del índice HOMA en un grupo de hombres adolescentes con factores de riesgo para el desarrollo de diabetes. Materiales y métodos: estudio descriptivo de corte transversal. Participaron adolescentes con algún factor de riesgo para diabetes. Se determinó la presencia de síndrome metabólico empleando los criterios de ATPIII modificada por Cook. Se determinaron T3, T4, TSH e insulina basal. Se calculó el índice HOMA para resistencia a la insulina. Resultados. Se estudiaron 36 hombres con una edad promedio de 15.97±0.9 años. En la población total existió correlación positiva entre T3 y HOMA-IR (r=0.380 p=0.022), cuando se analizó en el grupo de SM la correlación se incrementó entre T3 y HOMA-IR (r=0.647 p=0.031). Determinando que existe correlación positiva entre los índices de resistencia a la insulina y las concentraciones de hormona tiroidea.

Objetive. Establish the correlation between serum triiodothyronine concentrations and insulin resistance by HOMA index in a group of adolescent men with risk factors for developing diabetes. Material and Methods. It´s a descriptive cross-sectional study. Participating adolescents with some risk factor for diabetes. The presence of metabolic syndrome using the modified ATPIII criteria determined by Cook. T3, T4, TSH and basal insulin were determined. HOMA index was calculated for insulin resistance. Results. 36 men with an average age of 15.97 ± 0.9 years were studied. There was positive correlation between T3 and total population HOMA-IR (r = 0.380 p = 0.022), when analyzed in the group of SM correlation increased between T3 and HOMA-IR (r = 0.647 p = 0.031). Metabolic syndrome in adolescents with a positive correlation between indices of insulin resistance and thyroid hormone concentrations.

Educação e promoção à saúde: comportamento e conhecimento de adolescentes de colégio público e particular em relação ao papilomavírus humano / Education and promotion to the health: behavior and knowledge of public and particular college in relation to the human papilomavírus

Introdução: o papilomavírus humano (HPV) é uma das doenças sexualmente transmissíveis (DST) mais comuns. Na adolescência, as atividades biológicas, falta de informação ou conceitos equivocados, facilitam a transmissão de doenças sexuais. Como a incidência de HPV entre os jovens está cada vez maior, é importante realizar trabalhos que demonstrem o perfil e o conhecimento dos jovens relacionados ao tema. Objetivo: verificar o perfil dos alunos de um colégio público e de um particular e avaliar o grau de conhecimento a respeito do HPV. Métodos: foi realizado um estudo descritivo, de campo, por observação direta extensiva. O público-alvo desta pesquisa foi composto por adolescentes, estudantes do terceiro ano do ensino médio, em dois colégios do município de Tubarão, SC. Para a coleta de dados utilizou-se um questionário constituído de perguntas referentes ao comportamento sexual dos alunos e sobre o grau de informação sobre o HPV. Resultados: foram entrevistados ao todo 121 adolescentes. Observou- se que, 55,22% dos alunos do colégio particular sabem o que é HPV, enquanto no colégio público, 81,48% nunca ouviram falar ou não sabem o que é HPV. Afirmaram que não tiveram relação sexual 61,19% e 62,96% dos alunos do colégio particular e público, respectivamente; dos que já iniciarama vida sexual, alguns alunos tiveram sua primeira relação com uma idade bastante precoce. Conclusão: apesar de os alunos do colégio particularterem demonstrado maior conhecimento, faz-se necessária a implementação de medidas educativas, que possam minimizar a falta de informação e equívocos com relação ao HPV.

Introdution: the human papilomavirus (HPV) represents one of the most common sexually transmitted disease (DST). In the adolescence the biological activity, lack of information and mistaken concepts, facilitate the transmission of sexual diseases. Since the growth of HPV is getting biggeramong the adolecents, its important to make a study that could demonstrate the profile and knowledge of the adolecents related to this topic. Objective: check the studants profile in public and private schools and evaluate their knowledge degree concerning HPV. Methods: a written study was done by direct extensive observation. The aim public of the research were adolecents students on their last year oh high school in two schools in Tubarão, SC. To collect the data we used a questionnaire where there knowledge about HPV. Results: 121 students were interviewed. We observed that 55,22% of the private school students know what HPV is, where as in public school, 81,43% have never heard or don?t know what HPV is. They claimed that 61,19% and 62,92% of the students in public and private school respectively, never had sexual intercourse, but those who already started their sexual life, some of them had their first sexual intercourse at an early age. Conclusion: in spite of the private school have demonstrated a bigger knowledge, it?s necessary that some educational measures be done to minimize the lack of information and mistakes in relation to HPV.
