Níveis de obesidade associados à aptidão física, comportamentos de saúde e factores psicossociais: estudo da população escolar do 5º ao 12º anos de escolaridade do Concelho de São Vicente

Através de dois estudos, o presente trabalho pretende caracterizar a população escolar do 5.º ao 12.º anos de escolaridade do concelho de São Vicente, relativamente aos níveis de obesidade associados à aptidão física, comportamentos de saúde e factores psicossociais. Metodologia: A amostra total é constituída por 421 crianças e adolescentes com idades compreendidas entre os 10 e os 21 anos, dividida em três grupos etários (GE), representando 87,2% da população escolar do 5.º ao 12.º anos do concelho de São Vicente. Os níveis de obesidade foram caracterizados através de: 1) índice de massa corporal (IMC), segundo proposto por Cole et al. (2000) para o excesso de peso e obesidade, Cole et al. (2007) para a subnutrição, e Organização Mundial de Saúde (OMS, 2006b), para sujeitos com idade superior a 18 anos; 2) percentagem de massa gorda (%MG), calculada através das equações de Slaughter et al. (1988), até aos 17 anos de idade, e classificada segundo as categorias de Lohman (1987); 3) perímetro da cintura, para classificar a Obesidade Abdominal (OA), segundo Katzmarzyk et. al (2004), para indivíduos com idade inferior a 18 anos, e pela International Diabetes Federation (IDF, 2006). Os comportamentos e factores psicossociais foram obtidos com recurso à aplicação de escalas auto-reportadas por questionário. Conclusões: No primeiro estudo, verificou-se que 19,0% dos indivíduos têm excesso de peso e 5,7% são obesos, 10,4% têm %MG alta e 12,4% excessivamente alta, e 34,9% têm OA, verificando-se também 2,9% de subnutridos e 2,1% com %MG baixa. As raparigas apresentaram prevalências superiores em todas estas classificações, com excepção para a %MG baixa onde os rapazes apresentam taxas superiores. Ao nível da aptidão física criterial, observou-se uma maior taxa de insucesso nos testes de aptidão muscular relacionados com a força, e de sucesso no teste de flexibilidade, com os rapazes a apresentarem taxas de sucesso superiores, com excepção da extensão do tronco. O vaivém é o melhor preditor de factores de risco independentemente do método de classificação de obesidade usado, com o risco a oscilar entre 3,162 (IC95% 1,883 - 5,308 na %MG) e 2,582 (IC95% 1,604 - 4,157 na OA). No segundo estudo, os alunos com OA afirmam, em média, ter um pouco de peso a mais e estarem a tentar perdê-lo, e apresentam uma percepção de saúde mais negativa comparativamente com os que não têm OA. A falta de tempo é um argumento mais utilizado pelos alunos com OA para a não realização de actividade física, em comparação com os seus pares sem OA. Estes consideram o facto de serem bons a praticar desporto como sendo uma motivação importante para o fazerem, e são os que referem andar rápido nos intervalos durante mais tempo.

Variação da atividade locomotora do ermitão Clibanarius Vittatus (BOSC, 1802) em relação à dessecação, na praia dos pescadores, em São Vicente (SP), Brasil

The crustaceans activity of move about could alter in function of the environmental conditions. In the present study, this activity of the hermit crab Clibanarius vittatus was studied in dry and submerged areas of the intertidal region of Pescadores Beach in Sao Vicente (SP), Brazil. In both areas 110 animals (86 of dry and 24 of submerged area) were analyzed and C. vittatus show more activity in the submerged area than in the dry one. The low activity of locomotion presented when exposed to the air, can be due by the stress caused in function of the high temperature and desiccation.

Growth of the hermit crab Clibanarius vittatus (Bosc, 1802) (Crustacea, Anomura, Diogenidae) at São Vicente, São Paulo, Brazil

O presente estudo teve como objetivo analisar o crescimento de machos e fêmeas do ermitão Clibanarius vittatus (Bosc, 1802), da região de São Vicente, São Paulo, Brasil. Foram realizadas coletas mensais de maio/2001 a abril/2003, na Praia dos Pescadores em São Vicente. Os 2.501 animais capturados foram identificados, determinados quanto ao sexo e mensurados quanto ao seu comprimento de escudo cefalotorácico (CEC). Para o estudo sazonal do crescimento, a população foi dividida em classes de tamanho de 5mm de (CEC), e analisada pelo método de Bertalanffy, com o auxílio do software Fisat II. Foram obtidos 703 indivíduos machos e 1.798 fêmeas, com média de tamanho de 8.94±1.80 e 6.61±1.13mm, respectivamente. Constatou-se um padrão de crescimento sazonal, com machos atingindo um tamanho assintótico (14.92mm) superior ao das fêmeas (13.85mm), além de iniciarem o processo de crescimento aproximadamente cinco meses antes destas. Desta forma, é provável que este seja um padrão que auxilia na diminuição da disputa intra-específica por conchas, uma vez que os machos atingiram maior tamanho e estariam disponibilizando conchas menores para as fêmeas.

São Vicente (RN) nos primeiros anos da TV: Memória, sociabilidade e cotidiano

The present work aims to reflect on the everyday and its Vincentian practices of sociability in the early years of the presence of television in the city of São Vicente (RN), from the memories of the protagonists who witnessed the first insertion of TV set sin the beginning sof 1970s.Thus, the research was guided by some questions deemed relevant to the study in order to understand the most significant changes in the daily Vincentian boosted by the arrival of television in some private houses, which soon became a meeting place, recreation and sociability. At that time, filled the role of TV unites and brings people together. These houses, reinvented in spaces of sociability, were sanctioned by the various actors who gathered daily to include television programming. This popularity of television was measured by the joint efforts of people who moved their homes to homes that had this technical device. Each home with their uniqueness sand peculiarity, which attracted the population frequency f these spaces were frequent. Of course people still sit on the sidewalks, to be held the night rides in the streets and square, but soon came to the program schedule Preferred came into leaving their homes or to homes that had TV, watch them in the design of audiovisual programs. We use the oral memory as the principal methodology in order to interpret the memories recounted by people who lived in that time period studied. For this purpose we constructed a narrative that highlights the categories memory, media, social practices, everyday life and thus has the theoretical and methodological contributions of authors of humanities and social sciences its main foundation. In field research in the use of in-depth interviews, since the narratives of our research is interviewed. The importance of a study of such order, is not only in understanding the TV as an essential mediator for the interaction of individuals in society, from 1970 in São Vicente (RN), but also for the unveiling of his relationship with the daily routines of the Vincentians, founded in environments and symbols that regulated the conduct and reordered the social practices and sociability of these subjects. In this sense, the making of a work on the presence of TV in the city of São Vicente (RN) is also of paramount importance for the history of this media at the national level, since this is nothing more than a set of multiple stories

Shell utilization pattern of the hermit crab Clibanarius vittatus (Crustacea, Anomura) in an estuary at São Vicente, State of São Paulo, Brazil

O objetivo do presente estudo foi avaliar a utilização de conchas de gastrópodes por Clibanarius vittatus (Bosc, 1802), na Praia dos Pescadores, em São Vicente (SP), Brasil. Foram realizadas amostras mensais no período de maio de 2001 a abril de 2003, na região intertidal durante a maré baixa. Todos os animais foram pesados e tiveram o comprimento de seu escudo cefalotorácico mensurados, suas conchas identificadas e medidas quanto ao comprimento (mm), abertura (mm) e peso (g). Capturamos 2.344 ermitões (644 machos, 1.594 fêmeas não-ovígeras, 45 fêmeas ovígeras e 61 em intersexo), utilizando 13 espécies de conchas de gastrópodes, das quais Stramonita haemastoma (Linnaeus, 1767), Cymatium parthenopeum (Von Salis, 1793) e Achatina fulica (Bowdich, 1822) representaram mais de 98% das conchas utilizadas. Obteve-se significativa diferença de tamanho entre os sexos, com machos e indivíduos em intersexo atingindo maior porte físico do que fêmeas. Este padrão influenciou fortemente na ocupação e utilização de conchas, principalmente em A. fulica, que foi a maior concha obtida por C. vittatus, utilizada somente por machos e indivíduos em intersexo. Cymatium parthenopeum foi a única espécie de concha em que se obtiveram elevados coeficientes de determinação para todas os parâmetros analisados. Stramonita haemastoma apresentou elevados e significativos coeficientes de determinação, indicando que esta espécie é o principal recurso de concha ocupada na Praia dos Pescadores.

Utilization of shells of the snail Achatina fúlica Bowdich, 1822 (Mollusca, Gastropoda) by the hermit crab Clibanarius vittatus (Bosc, 1802) (Decapoda, Anomura) in the São Vicente Estuary, São Paulo, Brazil

Hermit crabs depend on mollusc shells for housing. In this study, an unusual resource is reported for a hermit crab that usually inhabits marine gastropod shells. During a field study conducted from May 2001 to April 2003 in an estuarine area in São Vicente, state of São Paulo, Brazil, 21 individuals of Clibanarius vittatus (Bosc, 1802) were found inhabiting the shells of the terrestrial gastropod Achatina fullea Bowdich, 1822. A. fúlica occurs in nearshore grass patches, where occasional contact with sea water kills them, and their shells then become available to the hermit crabs.

Spatial distribution and shell utilization in three sympatric hermit crabs at non-consolidated sublittoral of estuarine-bay complex in São Vicente, São Paulo, Brazil

The objective of the present study was to characterize the spatial distribution and shell utilization of three hermit crab species in the estuarine-bay complex of São Vicente, São Paulo State, Brazil. Monthly samples were done throughout two years, in the non-consolidated sub-littoral at the estuarine-bay complex. The environmental factors, such as temperature, salinity and depth, were measured every month. The three hermit crab species, Clibanarius vittatus, Loxopagurus loxochelis and Isocheles sawayai, were captured utilizing shells from six gastropods species; 92.7% of the hermit crabs utilized Stramonita haemastoma. The results suggest a strong correlation between hermit crabs spatial distribution and salinity, which was considered the main environmental factor limiting their distribution in the estuary. I. sawayai was the only species present in all transects sampled; C. vittatus was captured only in regions with low salinity and L. loxochelis occurred only in high salinity waters.

Environmental parameters and antimicrobial susceptibility of enterobacteriaceae isolated from estuarine waters of São Vicente, São Paulo State, Brazil

Diseases transmitted by water consists a serious public health problem and enterobacteria are the main group of microorganisms responsible for outbreaks in humans. Such pathogenic bacteria proliferate in water polluted by domestic and industrial sewage and reach the population through seawater contact. The aim of the present work was to study environmental parameters as well as to identify Enterobacteriaceae species and their antimicrobial susceptibility in water samples collected from the estuarine area of São Vicente city (São Paulo State, Brazil). Strains were identified by using traditional biochemical tests described in literature and antimicrobial susceptibility tests were carried out using the disk diffusion method. Out of 26 samples, Escherichia coli was the most frequent species (40.1%), followed by Citrobacter, Enterobacter and Klebsiella. The most effective drugs against the tested microorganisms were gentamycin, netilmicin, ciprofloxacin and cefepime. Since these bacteria are commonly found in seashore contaminated by sewage effluents, it can be concluded that estuarine waters of São Vicente are polluted and potentially capable of causing diseases and spreading pathogenic bacteria to human communities.

Densidade de Enterococcus sp em águas recreacionais e areias de praias do município de São Vicente-SP, Brasil e sua relação com parâmetros abióticos

Coastal cities attract a large number of tourists for their beautiful landscape and recreational activities, increasing the municipalities' income source. Thus, a need is clear for the establishment of beach quality monitoring programs to ensure bathers health. Although there is an effective monitoring program for recreational waters in Brazil there are no programs to certify the quality of beach sands. In this sense, the aim of this work was to analyze the density of bacteria from the genus Enterococcus in both sand and water from two beaches from São Vicente, São Paulo (Brazil) and correlate these densities to abiotic parameters such as: temperature, salinity, particle size, organic matter and tides). Water and sand samples were collected during February 2006 on the beaches of Gonzaguinha e Ilha Porchat and bacterial densities were determined by membrane filter technique. Temperature and salinity were measured in situ with a thermometer and a refractometer while particle size and organic matter were determined according to methods described by Suguio and Dean. There were significant differences between densities found in water and sand (p=0.004), being approximately 20 times higher in Gonzaguinha's beach sands. Similar results were found for Ilha Porchat beach samples, being the densities found in sand 3 times greater than those found in water. Both beaches showed a negative correlation between bacterial densities and salinity and temperature, suggesting a deleterious effect of these parameters on the bacterial community. On the other hand, no correlation was found between organic matter and particle size and bacterial densities. This work demonstrates that there is a great necessity for monitoring beach sand since the evaluation of beach quality is an important part of integrated coastal management programs.

Integrated quality assessment of sediments from harbour areas in Santos-São Vicente Estuarine System, Southern Brazil

Santos-São Vicente Estuarine System is a highly populated coastal zone in Brazil and where it is located the major port of Latin America. Historically, port activities, industrial and domestic effluents discharges have constituted the main sources of contaminants to estuarine system. This study aimed to assess the recent status of sediment quality from 5 zones of Port of Santos by applying a lines-of-evidence approach through integrating results of: (1) acute toxicity of whole sediment and chronic toxicity of liquid phases; (2) grain size, organic matter, organic carbon, nitrogen, phosphorus, trace metals, polycyclic aromatic hydrocarbons, linear alkylbenzenes and butyltins; (3) benthic community descriptors. Results revealed a gradient of increasing contamination for metals and organic compounds, alongside with their geochemical carriers. Sediment liquid phases were more toxic compared to whole sediment. Low number of species and individuals indicated the impoverishment of benthic community. The use of site-specific sediment quality guidelines was more appropriate to predict sediment toxicity. The integration of results through Sediment Quality Triad approach and principal component analysis allowed observing the effects of natural stressors and dredging on sediment quality and benthic distribution. Even with recent governmental efforts to control, pollution is still relevant in Port of Santos and a threat to local ecosystems. © 2013 Elsevier Ltd.
