ABSTRACT
OBJECTIVE: To investigate the association between behavioral risk factors, specifically postural habits, with the presence of structural changes in the spinal column of children and adolescents. METHODS: 59 students were evaluated through the self-reporting Back Pain and Body Posture Evaluation Instrument and spinal panoramic radiographic examination. Spine curvatures were classified based on Cobb angles, as normal or altered in the saggital plane and as normal or scoliotic in the frontal plane. Data were analyzed using SPSS 18.0, based on descriptive statistics and chi-square association test (a=0,05). RESULTS: The prevalence of postural changes was 79.7% (n=47), of which 47.5% (n=28) showed frontal plane changes and 61% (n=36) sagital plane changes. Significant association was found between the presence of thoracic kyphosis and female gender, practice of physical exercises only once or twice a week, sleep time greater than 10 hours, inadequate postures when sitting on a seat and sitting down to write, and how school supplies are carried. Lumbar lordosis was associated with the inadequate way of carrying the school backpack (asymmetric); and scoliosis was associated wuth the practice of competitive sports and sleep time greater than 10 hours. CONCLUSIONS: Lifestyle may be associated with postural changes. It is important to develop health policies in order to reduce the prevalence of postural changes, by decreasing the associated risk factors. .
OBJETIVO: Verificar se existe associação de fatores de risco comportamentais, especificamente hábitos posturais, com a presença de alteração postural estrutural na coluna vertebral de crianças e adolescentes. MÉTODOS: Foram avaliados 59 crianças e adolescentes, que responderam ao questionário auto-aplicável Back Pain and Body Posture Evaluation Instrument e fizeram o exame radiográfico panorâmico da coluna vertebral. De acordo com o ângulo de Cobb, as curvaturas sagitais da coluna vertebral foram classificadas como normais ou alteradas e, no plano frontal, como escolioses ou normais. Os dados foram analisados no SPSS 18.0, a partir de estatística descritiva e do teste de associação qui-quadrado (a=0,05). RESULTADOS: A prevalência de alterações posturais foi de 79,7% (n=47), 47,5% (n=28) apresentavam alteração no plano frontal e 61% (n=36) no sagital. Foi encontrada associação entre cifose torácica e sexo feminino, prática de exercício físico apenas uma ou duas vezes na semana, tempo de sono superior a 10 horas, posturas inadequadas para sentar no banco e sentar para escrever e o meio de transporte do material escolar. Para lordose lombar, observou-se associação com o transporte da mochila escolar de modo inadequado (assimétrico). Houve associação significativa entre a presença de escoliose com a prática de esporte competitivo e o tempo de sono superior a 10 horas. CONCLUSÕES: Hábitos de vida podem estar associados a alterações posturais, é importante o desenvolvimento políticas de saúde a fim de reduzir a prevalência de alterações posturais por meio da redução dos fatores de risco associados. .

A series of quinolinoxy methyl-1,3,4-oxadiazoles [2 and 3], N-imido derivatives [5,6], pyrazole [7], pyrazolone [8], pyrazolidindione [9], Schiff bases [10a-f] and 8-O [2-oxo-3-indolinylidene] acetic acid hydrazido] 5,7 diiodoquinoline [4] was prepared. Some of the new compounds showed considerable antimicrobial activity against Gram +ve and Gram -ve bacteria, yeast and fungi
