ResumoObjetivo: traduzir e adaptar o PCATool versão usuários adultos ao contexto brasileiro e avaliar sua validade e fidedignidade. Métodos: Foi realizado um estudo transversal no qual foram entrevistados 2.404 usuários adultos residentes nas áreas adscritas da rede pública dos serviços de Atenção Primária à Saúde (APS) em Porto Alegre e usuários vinculados a um plano de autogestão. O processo de validação constituiu-se de tradução e tradução reversa, adaptação, validade de conteúdo, validade fatorial e fidedignidade. Resultados: Na análise fatorial, foram considerados 12 fatores que explicaram 50,83% da variação total. Assim, foram reconhecidos os seguintes atributos da APS: acesso -acessibilidade e utilização, longitudinalidade, coordenação -coordenação do cuidado e sistemas de informação, integralidade -serviços disponíveis e serviços prestados, enfoque familiar e orientação comunitária. Para a consistência interna, foi obtido alfa de Cronbach variando de 0,15 a 0,90. A estabilidade temporal não foi verificada para coordenação do cuidado (p<0,05), coordenação de sistema de informação (p<0,05) e integralidade de serviços prestados (p<0,05). Na razão êxito da escala, todos os componentes/atributos apresentaram valores próximos de 100%, à exceção do componente sistema de informação. Conclusões: os resultados indicaram que o PCATool-Brasil possui adequada validade e fidedignidade, podendo constituir-se em instrumento nacional de avaliação da APS para usuários adultos. AbstractObjective: to translate and adapt the PCATool version for adult users to the Brazilian context and assess its validity and reliability. Methods: We conducted a cross-sectional study of 2404 adult users living in areas covered from public services Primary Care in Porto Alegre, and users of a selfmanagement plan. We performed translation, reverse translation and adaptation of the instrument as well as its assessment in respect of content validity, factorial validity and reliability. Results: In the factor analysis were considered 12 factors that explained 50.83% of the total variation. In this way were recognized the attributes of Primary Care: access -accessibility and utilization; longitudinality; coordination -coordination of care and systems of information; comprehensiveness -services available and services provided; family orientation; and community orientation. In terms of internal consistency the values of Cronbach's alpha ranged from 0.15 to 0.90. The stability over time was not observed for coordination of care (p<0.05), coordination information of system (p<0.05) and comprehensiveness of services provided (p<0.05). The scaling success rate was close to 100% for all attributes, except to coordination of information system. Conclusions: the results indicated that the PCATool-Brazil has adequate validity and reliability, and it can act as a national instrument for the assessment of Primary Care from the perspective of adult users.
CONTEXT AND OBJECTIVE: Scoliosis is not a diagnosis, but a description of a structural alteration that occurs in a variety of conditions. Progression of the curvature during periods of rapid growth may result in severe deformity, which may be accompanied by cardiopulmonary compromise. This study had the aims of measuring the prevalence of scoliosis among students in the fifth to eighth school years and investigating possible associations between the presence of scoliosis, body overweight and the weight of school materials. DESIGN AND SETTING: Analytical cross-sectional study developed in the municipality of Carlos Barbosa, Rio Grande do Sul, Brazil. METHODS: A total of 1340 students were evaluated. The variables studied were the prevalence of scoliosis, type of school, location of the school, age, school year, sex, body weight, prevalence of excessive school material weight, height, body mass index (BMI) and spinal alignment measurements. RESULTS: The prevalence of scoliosis was 1.4%; shoulder and scapula asymmetry, 6.6%; forearm and trunk asymmetry, 4.0%; spinal misalignment, 1.9%; Thales triangle asymmetry, 6.4%; body overweight, 19.8%; and carrying of excessively heavy school materials, 27%. The study did not find any statistically significant association between scoliosis and body overweight, or between scoliosis and excessive weight of school materials. CONCLUSIONS: The prevalence of scoliosis in this school-based sample was low. No correlation was found between this clinical condition and the other variables.
