Förhållandet mellan BMI och hälsa hos värmländska skolungdomar : en kvantitativ empirisk studie

Eriksson, Lina, Sjökvist, Emma January 2016 (has links)
Introduktion: Barnfetma är en av vår tids största folkhälsoutmaningar och forskning har visat att övervikt hos barn kan leda till en lägre självuppskattad hälsa och sämre livskvalitet. Syfte: Syftet var att utifrån ELSA-studiens hälsoenkät beskriva hälsan hos värmländska skolungdomar i årskurs sju samt sambandet mellan ungdomarnas BMI och hälsa. Metod: Studien är en kvantitativ empirisk studie genomförd på 4381 värmländska skolelever i årskurs sju och en delstudie i projektet ELSA. Resultatet har analyserats med hjälp av deskriptiv och analytisk statistik. Resultat: Resultatet av denna studie visade att värmländska skolungdomar i årskurs sju skattade sin hälsa högt. Flickor skattade sin hälsa något lägre än pojkar. Hälsan skattades signifikant lägre hos gruppen elever med fetma i jämförelse med mer normalviktiga elever. Elever med fetma var även mer missnöjda med sin kropp, åt inte frukost lika regelbundet och var mindre fysiskt aktiva. Konklusion: Denna studie visar att knappt en fjärdedel av alla värmländska elever i årskurs sju är överviktiga. Trots detta upplever skolungdomarna att de mår bra och skattar sin hälsa högt. / ELSA

Aspectos biomecânicos e morfofuncionais do esqueleto apendicular de Prestosuchus Chiniquensis (Archosaurua : Pseudosucha) e suas implicações para a locomoção

Liparini, Alexandre January 2011 (has links)
O estudo das estruturas osteológicas e da musculatura a estas relacionadas permite compreender, em animais extintos, a evolução dos traços associados aos seus hábitos locomotores, especialmente se este estudo considerar os seus representantes atuais, a fim de se estabelecer as relações de homologia e analogia entre as estruturas comparadas e suas respectivas funções inferidas. Além disso, em uma análise biomecânica de espécies fósseis, deve-se considerar, mesmo que de forma aproximada, a massa corporal como atributo fundamental. Prestosuchus chiniquensis é uma espécie extinta de arcossauro terrestre relacionada à linhagem dos crocodilos atuais. Para testar as hipóteses de hábitos locomotores deste táxon, foi feita a reconstrução muscular da coxa do espécime UFRGS-PV-0629-T, com base nas descrições musculares de aves e crocodilos. Observou-se que o conjunto muscular considerado em P. chiniquensis, de uma forma geral, é bastante semelhante ao dos representantes atuais. Dos dezesseis grupos musculares da coxa avaliados, treze foram reconhecidos como presentes e homólogos entre os dois grupos de arcossauros viventes comparados, de modo que a reconstrução destes músculos, no exemplar fóssil analisado, se mostrou a opção mais parcimoniosa, envolvendo o menor número de passos evolutivos. Por outro lado, a morfologia da cintura pélvica e dos membros posteriores confere uma disposição distinta dos locais de origem e inserção desta musculatura, com possível alteração das linhas de ação dos mesmos. Por fim, a comparação com formas arcossaurianas extintas e atuais mostrou uma condição basal mantida para a morfologia do fêmur e a flexão do joelho, enquanto a morfologia do púbis e do ísquio – e a origem da musculatura a eles associada – revelou um padrão derivado. Paralelamente, diversas metodologias para a estimativa da massa de formas extintas foram aplicadas e comparadas, com o intuito de realizar inferências biomecânicas para o hábito locomotor de P. chiniquensis. O espécime considerado, com 4,5 m de comprimento total, apresentou uma massa média estimada de 400 kg, a qual, em conjunto com a morfologia geral dos ossos dos membros posteriores, se mostrou compatível com um hábito locomotor subcursorial, além de uma postura preferencialmente mesógrada e quadrúpede. Contudo, devido ao caráter generalista inferido – permitindo uma ampla gama de posturas admissíveis – foi sugerida uma estratégia de caça por emboscada, na qual P. chiniquensis adotaria uma postura bípede e ortógrada, que poderia conferir à espécie vantagens, tal como uma maior velocidade em relação à postura usual. / Studying osteological structures and its associated musculature may help to understand the evolution of locomotor traits in extinct animals, especially if this study considers their extant relatives, in order to set up homologies and analogies between the compared structures and their inferred functions. Furthermore, in a biomechanical analysis of the fossil record one should consider the estimated body mass as a fundamental attribute. Prestosuchus chiniquensis is an extinct species of terrestrial archosaur related to extant crocodiles. To test different hypotheses related to the locomotion of this taxon, the muscular reconstruction of the thigh of the specimen UFRGS-PV-0629-T was realized, based on the muscular descriptions of extant birds and crocodiles. It was observed that the main muscular groups considered for the reconstruction of P. chiniquensis were similar in birds and crocodiles in a general manner. Among sixteen muscular groups of the thigh that were analyzed, thirteen were recognized as present and homolog to both extant groups of archosaurs, so that the reconstruction of those muscles in the analyzed fossil specimen showed to be the most parsimonious option, involving the least number of evolutionary steps. On the other hand, the morphological particularities of the pelvic girdle and the hindlimbs gave a distinct arrangement for the origin and insertion sites of this musculature, possibly changing their line of actions. Finally, the comparison between extinct and extant archosaurs showed a basal condition sustained in some aspects, such as the morphology of the femur and the flexion of the knee, though, other aspects were considered as derived, such as the morphology of the pubis and ischium, and their associated muscle origins. At the same time, different methodologies for estimating body mass of fossil specimens were applied, and compared in order to make biomechanical inferences of the locomotors habits of P. chiniquensis. The specimen considered, approximately 4.5 m long (15 ft), presented an estimated mass of 400 kg (around 880 lbs), which, with the general morphology of the hindlimbs, were consistent with a subcursorial locomotor habit, with a preferential “semi-improved” and quadruped posture. However, due to the generalist character inferred for P. chiniquensis – which permitted a wide range of feasible postures – an ambush hunting strategy, with a biped and totally improved posture, may be admitted, possibly conferring some advantages, such as higher speeds, if compared to usual postures.

Metodologia: Para este estudo clínico e analítico foram selecionadas 303 mulheres com idade entre 29 e 89 anos (pacientes em consultas médicas de rotina acompanhadas no Ambulatório de Mastologia da Faculdade de Medicina de Botucatu) no período de março 2006 à julho de 2007. Incluíram-se pacientes portadoras de câncer de mama (somente), em quaisquer estádios que já foram tratadas para câncer de mama (cirurgia e/ou radioterapia e/ou quimioterapia e/ou hormonioterapia). Foram excluídas pacientes em fase de diagnóstico inicial de câncer de mama (sem tratamento), pacientes com outros tipos de neoplasias malignas concomitantes. Todas foram submetidas ao International Physical Activity Questionnaire (IPAQ - short version), onde foram classificadas em três níveis de atividade física (leve, moderada e intensa); obtivemos também através de questionário clínico/sócio-demográfico os seguintes dados: escolaridade, renda (salarial), religião, hipertensão, diabetes, problemas osteoarticulares, tipo de cirurgia (mastectomia ou conservadora), tipos de tratamento (quimioterapia, radioterapia e hormonioterapia), tempo de diagnóstico do câncer de mama, menopausa e tempo de menopausa; e através de prontuário obtivemos: idade, peso e altura. Resultados: Houve diferença significativa (p<0,001) quando comparamos a atividade física das pacientes pré e pós-tratamento, e quando comparamos a atividade física com o período de cirurgia, nota-se claramente que as pacientes principalmente após o segundo ano de cirurgia melhoram gradativamente seus níveis de atividade física deixando de praticá-las em níveis leves, começando a praticá-las em níveis moderados e intensos (p=0,0365). / To assess physical activity in patients with breast cancer before (self-report) and after treatment through validated questionnaire. Method:, A total of 303 women aged 29-89 years attending routine follow up at the Mastology Outpatient Clinic of Botucatu Medical School) between March/2006 and July/2007 were enrolled in this clinical and analytical study. Women with breast cancer (alone) at any stage, previously submitted to breast cancer treatment (surgery and/or radiotherapy and/or chemotherapy and/or hormone therapy) were included. Patients newly diagnosed with breast cancer (untreated) and those with other kinds of concurrent malignant neoplasia were excluded. All women were administered the International Physical Activity Questionnaire (IPAQ - short version). Physical activity was classified as light, moderate and intense. Through a clinical/sociodemographic questionnaire, data were collected on schooling level, income (salary), religion choice, hypertension, diabetes, osteoarticulary problems, type of surgery (mastectomy or conservative), type of treatment (chemotherapy, radiotherapy and hormone therapy), time since breast cancer diagnosis, menopause and time since menopause. Information such as age, weight and height was extracted from the patients’ medical records. Results: There was a significant difference between pre- and post-treatment physical activity (p<0,001). The assessment of physical activity at different postoperative times clearly showed that physical activity levels gradually increased from mild to moderate or intense(p=0,0365), especially after the second postoperative year. A significant increase (p<0,001) in the frequency of comorbidities (hypertension, diabetes and osteoarticulary problems) was observed after treatment of breast carcinoma, as well as in patients submitted to chemotherapy in comparison with those who did not receive this kind of treatment (p=0,006).
