Articulação saúde-escola: a intervenção em contexto comunitário

As perturbações psiquiátricas e os problemas de saúde mental infantojuvenil têm vindo a merecer especial atenção por parte da comunidade científica, não só pelo facto de se estimar que 10 a 20% das crianças apresentem um ou mais problemas de saúde mental, não só por estes valores terem tendência a aumentar, mas também pelo impacto humano e financeiro que acarretam para a sociedade. Em Portugal, o Plano Nacional da Saúde Mental 2007-2016 é categórico ao afirmar a necessidade de promover a saúde mental infantojuvenil junto da população e ao salientar a importância do envolvimento e articulação com outras estruturas comunitárias ligadas à saúde, educação e direito de menores. Este trabalho vai de encontro a estas linhas de orientação, na medida em que procura identificar, desenvolver e implementar diversos aspetos inerentes à vertente comunitária da saúde mental infantojuvenil. Numa primeira fase é realizado um levantamento das reais necessidades da população infantojuvenil do concelho de Odemira e é definida uma rede de articulação entre os serviços de saúde, escolas e outras entidades locais com competência nesta área. De forma a melhorar a prestação dos cuidados e a garantir respostas adequadas às necessidades identificadas, também se procurou o individual desenvolvimento de competências especializadas na área da saúde mental infantojuvenil. Por último, atendendo à importância da implementação atempada de medidas preventivas de determinados fenómenos psicopatológicos, procurou-se treinar e desenvolver a capacidade de sensibilização e reforço de competências de uma bolsa populacional específica: a comunidade escolar. De um modo geral, os resultados obtidos demonstram aplicabilidade na prática clínica dos cuidados, contribuindo para a melhoria dos mesmos. Algumas das estratégias utilizadas constituem-se como ponto de partida para projetos futuros, podendo ser replicadas e adequadas a outros contextos de intervenção; ABSTRACT: LINK HEALTH-SCHOOL: the intervention in the community context Psychiatric disorders and problems of youth mental health have been given special attention by the scientific community, not only because it is estimated that 10-20% of children present one or more mental health problems, not only because these values have tendency to increase, but also the human and financial impact to society. In Portugal, the Mental Health National Plan 2007-2016 is emphatic in affirming the need to promote the mental youth health within the population and to emphasize the importance of the involvement and coordination with other community entities related to health, education and minors rights. This paper follows these guidelines, it tries to identify, develop and implement various aspects related to the Community part of youth health. In the first phase is carried out a survey of the real needs of youth population of the Odemira County and defined a network between health services, schools and other local organizations with expertise in this area. In order to improve the delivery of health care and ensure appropriate responses to the identified needs, also sought the individual development of expertise in the area of youth mental health. Finally, given the value of timely implementation of preventive measures of certain psychopathological phenomena, it sought to train and develop the awareness and skills improvement of a specific population: the school community. In general, the results prove the applicability of the procedures in clinical practice, contributing to a practice improvement. Some of the strategies used are the Foundation for future projects, they can be replicated and adapted to other contexts of intervention.

Land use and environmental factors affecting red-legged partridge (Alectoris rufa) hunting yields in southern Spain

The red-legged partridge is a small game species widely hunted in southern Spain. Its commercial use has important socioeconomic effects in rural areas where other agrarian uses are of marginal importance. The aims of the present work were to identify areas in Andalusia (southern Spain) where game yields for the red-legged partridge reach high values and to establish the environmental and land use factors that determine them. We analysed 32,134 annual hunting reports (HRs) produced by 6,049 game estates during the hunting seasons 1993/1994 to 2001/2002 to estimate the average hunting yields of red-legged partridge in each Andalusian municipality (n=771). We modelled the favourability for obtaining good hunting yields using stepwise logistic regression on a set of climatic, topographical, land use and vegetation variables that were available as digital coverages or tabular data applied to municipalities. Good hunting yields occur mainly in plain areas located in the Guadalquivir valley, at the bottom of Betic Range and in the Betic depressions. Favourable areas are related to highly mechanised, lowelevation areas mainly dedicated to intensive dry crops. The most favourable areas predicted by our model are mainly located in the Guadalquivir valley.

Obtaining environmental favourability functions from logistic regression

Logistic regression is a statistical tool widely used for predicting species’ potential distributions starting from presence/absence data and a set of independent variables. However, logistic regression equations compute probability values based not only on the values of the predictor variables but also on the relative proportion of presences and absences in the dataset, which does not adequately describe the environmental favourability for or against species presence. A few strategies have been used to circumvent this, but they usually imply an alteration of the original data or the discarding of potentially valuable information. We propose a way to obtain from logistic regression an environmental favourability function whose results are not affected by an uneven proportion of presences and absences. We tested the method on the distribution of virtual species in an imaginary territory. The favourability models yielded similar values regardless of the variation in the presence/absence ratio. We also illustrate with the example of the Pyrenean desman’s (Galemys pyrenaicus) distribution in Spain. The favourability model yielded more realistic potential distribution maps than the logistic regression model. Favourability values can be regarded as the degree of membership of the fuzzy set of sites whose environmental conditions are favourable to the species, which enables applying the rules of fuzzy logic to distribution modelling. They also allow for direct comparisons between models for species with different presence/absence ratios in the study area. This makes themmore useful to estimate the conservation value of areas, to design ecological corridors, or to select appropriate areas for species reintroductions.
