Programa de saúde da família: proposta para identificação de fatores de risco para o desenvolvimento neuropsicomotor / Family health program: proposal for identification of risk factors for neuropsychomotor development

OBJETIVOS: Este estudo teve por objetivos investigar a ocorrência de atraso no desenvolvimento neuropsicomotor em uma comunidade assistida pelo Programa de Saúde da Família (PSF) e verificar a sua associação com possíveis fatores de risco biológicos, ambientais e socioeconômicos. MÉTODOS: A amostra constou de 31 crianças, com 5 anos de idade, que foram avaliadas por meio do exame neurológico evolutivo (ENE) segundo roteiro proposto por Coelho (1999)*. O local do estudo foi o PSF do bairro de Brasilit, na Cidade de Recife, PE, Brasil, e os dados foram coletados mediante questionário contendo informações sobre a criança, sua mãe ou responsável, a situação socioeconômica da família e o domicílio. Para análise estatística dos resultados, utilizou-se o Qui-quadradode associação de Fisher, com nível de significância de 5 por cento. RESULTADOS: A coordenação apendicular foi o parâmetro que apresentou a maior frequência de déficit (90 por cento), e o equilíbrio estático foi o item menos comprometido (12,9 por cento). A frequência de déficit no equilíbrio estático foi mais elevada nas crianças que não participaram de creche (p=0,0163) e naquelas que passavam menor tempo com a mãe (p=0,0278). O déficit na persistência motora esteve estatisticamente associado à idade de início na creche (p=0,0415) e ao tempo pai-filho (p=0,0436). CONCLUSÕES: O PSF, além de se constituir num espaço valioso para o desenvolvimento de trabalhos desta natureza, demonstrou ser local adequado para o acompanhamento do desenvolvimento infantil.

OBJECTIVES: To investigate the occurrence of delayed neuropsychological and motor development in a community assisted through the Family Health Program and to evaluate its association with possible biological, environmental and socioeconomic risk factors. METHODS: The sample consisted of 31 five-year-old children who were evaluated using the Neurological Development Test, following guidelines proposed by Coelho (1999)*. The study was carried out at the Family Health Program (FHP) center in the Brasilit area of Recife, PE, Brazil. Data were collected using a questionnaire that sought information on the child, its mother/guardian, the family's socioeconomic status and residence. Fisher's exact test was used for the statistical analysis of the results, with a significance level of 5 percent. RESULTS: Appendicular coordination was the parameter with the highest frequency of deficits (90 percent) and static balance was the item least compromised (12.9 percent). The frequency of static balance deficits was higher among children who did not attend day care centers (p=0.0163) and among those who spent less time with their mother (p=0.0278). Motor persistence deficits were statistically associated with age of entry into day care (p=0.0415) and father-child time (p=0.0436). CONCLUSIONS: The FHP was not only a valuable setting for developing studies of this nature but also an appropriate setting for child development follow-up.

A reproducibility study on musculotendinous stiffness quantification, using a new transportable ankle ergometer device.

The use of biomechanical methods to quantify functional/physiological parameters in malnourished humans can provide new insights into the understanding of effects of malnutrition on human muscles. Therefore, a transportable ankle ergometer device was developed, which allows the quantification of mechanical properties of the human plantarflexor muscles in field experiments. More precisely, the ergometer quantifies isometric force in static conditions and musculotendinous stiffness in dynamic conditions. This latter parameter is obtained by the quick-release technique. The aim of the study was first to conduct a reproducibility study on musculotendinous stiffness. Seven healthy subjects were tested three times in alternate days. The results showed the well-known linear relationship between musculotendinous stiffness and torque, where the slope was used as a stiffness index (SI(MT)). Individual regression line comparison indicated that SI(MT) values were not significantly different between the three repeated measurements (P>0.05). Mean coefficient of variation was 4.5+/-1.0%. The individual SI(MT) data were within the range of those reported in the literature. The reproducibility study showed that the quantification of musculotendinous stiffness by means of the quick-release technique is a reliable method, using a transportable ankle ergometer device.

A regional model (Northeastern Brazil) of induced mal-nutrition delays ontogeny of reflexes and locomotor activity in rats.

The aim of this study was to investigate the effects of malnutrition, induced by a regional basic diet (RBD), on motor development. RBD is a 7.87%-protein diet based on aliments typical of Northeastern Brazil, elaborated after nutritional investigation by Teodosio et al. (1979). Female rats were treated with RBD during lactation. The reflex ontogenesis and the development of locomotor activity in their offspring were assessed. Malnourished (MN) rats showed a delay in reflex maturation and in locomotor activity evolution. The decreased locomotor activity may be related to the reduced movement experiences induced by the delay in the reflex maturation. Occurring during the critical period of brain development, this fact could jeopardize all the steps in future locomotion evolution. The present results confirm deleterious effects of RDB-induced malnutrition on the somatic development and maturation of the nervous system (NS).
