Hipertensão arterial sistêmica (HAS) é uma doença definida pela elevação mantida dos níveis pressóricos. Pode ser agravada pela presença de fatores de risco como dislipidemias, obesidade, intolerância à glicose, diabetes mellitus, tabagismo, sedentarismo, entre outros. Realizou-se estudo transversal a fim de determinar o perfil dos casos de HAS notificados no estado do Tocantins, Brasil, no período de 2002 a 2012. Foram coletadas e avaliadas informações presentes no banco de dados oficial do Sistema de Informação de Agravos de Notificação (SINAN). As variáveis analisadas foram idade, sexo, fatores de risco e ocorrência de complicações. Encontrou-se que, no estado do Tocantins, foram notificados 79.570 casos de HAS entre os anos de 2002 e 2012. A média anual foi de 7.233,64 casos/ano. Nesse período, 60,21% dos casos notificados correspondiam ao sexo feminino e 39,79% ao sexo masculino. Adultos acima de 40 anos de idade compreendeu o grupo etário mais acometido. O pico de ocorrência se deu em indivíduos entre 60 e 64 anos. Tabagismo, sobrepeso e sedentarismo, estiveram relacionados com muitos casos notificados, além de graves complicações cardiovasculares preveníveis. Sugere-se, então, que ações educativas de prevenção primária e secundária podem contribuir sobremaneira para diminuir a ocorrência desse agravo na região.

It may be aggravated by the presence of risk factors such as dyslipidemia, obesity, glucose intolerance, diabetes mellitus, smoking, sedentary lifestyle, among others. A cross-sectional study was carried out to determine the profile of cases of HTN reported in the state of Tocantins, Brazil, from 2002 to 2012. Data were collected and evaluated using the official database of the notification of invalidity information system. The analyzed variables were age, sex, risk factors and the occurrence of complications. It was found that in the state of Tocantins, 79,570 cases of HTN were reported between 2002 and 2012. The annual average was 7,233.64 cases/year. During this period, 60.21% of the reported cases were female and 39.79% were male. Adults over 40 years old comprised the most affected age group. The peak occurred in individuals between 60 and 64 years old. Smoking, overweight and sedentary lifestyle were related to many reported cases, as well as serious preventable cardiovascular complications. It is suggested, therefore, that educational actions of primary and secondary prevention can contribute greatly to reduce the occurrence of this disease in the region.
