title: Associated factors with mammographic changes in women undergoing breast cancer screening.
abstract: To evaluate association of sociodemographic, anthropometric, and epidemiological factors with result of mammogram in women undergoing breast cancer screening.
  This is a cross-sectional study with data obtained through interviews, anthropometric measurements, and mammography of 600 women aged 40 to 69 years at the Preventive Medicine Department of Hospital de Câncer de Barretos, Brazil, in 2014. The results of these examinations in the BI-RADS categories 1 and 2 were grouped and classified in this study as normal mammogram outcome, and those of BI-RADS categories 3, 4A, 4B, 4C, and 5 were grouped and classified as altered mammogram outcome. The statistical analysis included the Student's t-test to compare means, as well as odds ratios (OR), with their corresponding 95% confidence intervals (95%CI), to verify an association by means of the multivariate analysis.
  Of 600 women evaluated, 45% belonged to the age group of 40-49 years-old and 60.2% were classified as BI-RADS category 2. The multivariate analysis showed that women with blood hypertension (OR: 2.64; 95%CI: 1.07-6.49; p<0.05) were more likely to present changes in the mammography, while physical activity was associated with lower chances (OR: 0.30; 95%CI: 0.11-0.81; p<0.05).
  Hypertensive women undergoing screening mammography are more likely to present mammographic changes, whereas women practicing physical activity have lower chances (70%) of presenting changes in the breast compared with sedentary individuals.
  Avaliar a associação de fatores sociodemográficos, antropométricos e epidemiológicos com o resultado das mamografias de mulheres submetidas ao rastreamento.
  Trata-se de um estudo transversal com dados obtidos por meio de entrevistas, avaliação antropométrica e mamografia de 600 mulheres entre 40 a 69 anos, atendidas no Departamento de Prevenção do Hospital de Câncer de Barretos, em 2014. Os resultados de tais exames nas categorias BI-RADS 1 e 2 foram agrupados e classificados neste estudo como achado mamográfico normal, e aqueles das categorias BI-RADS 3, 4A, 4B, 4C e 5 como achado mamográfico alterado. Na análise estatística, utilizou-se o teste t de Student para comparar as médias, bem como odds ratio (OR), com seus respectivos intervalos de confiança de 95% (IC95%), na verificação de associação por análise multivariada.
  Das 600 mulheres avaliadas, 45% pertenciam à faixa etária dos 40 a 49 anos e 60,2% foram classificadas na categoria BI-RADS 2. Na análise multivariada, verificou-se que as mulheres com hipertensão arterial (OR: 2,64; IC95%: 1,07-6,49; p<0,05) apresentaram maiores chances de alteração na mamografia, enquanto que atividade física foi associada à menor chance (OR: 0,30; IC95%: 0,11-0,81; p<0,05).
  Mulheres hipertensas submetidas à mamografia de rastreamento tiveram maiores chances de apresentarem alterações mamográficas, ao passo que mulheres praticantes de atividade física apresentaram uma chance menor (70%) de terem alteração na mama em relação às sedentárias.
