Objective:To identify the association between blood pressure control and the following variables: a) bio-social and lifestyle characteristics of hypertensive patients; and b) factors related to the antihypertensive treatment. Methods: This is an exploratory study with 290 people with hypertension from primary care. We used a specific instrument, selfadministered, with 21 questions on factors that can hinder treatment, divided into four dimensions: medication, socioeconomic, institutional and personal beliefs. We adopted a significance level of p <0.05. Results: The control of blood pressure was associated (p <0.05) with female gender, Caucasian ethnicity, primary/secondary education, not drinking alcohol, higher income and regular physical activity. Regarding the factors that can hinder treatment, there was association of hypertension control with only two questions: "feel nothing" and "have to do treatment for life". Conclusion: Sociodemographic variables and beliefs concerning the absence of symptoms and chronicity of the disease influenced the control of hypertension and should be considered in the adherence process to the treatment.

RESUmoRealizou-se estudo comparativo randomizado para avaliar o controle de hipertensos, com uso da medida residencial da pressão arterial (MRPA) e medida casual, bem como para analisar o efeito do avental branco. Hipertensos atendidos em unidades básicas de saúde foram divididos aleatoriamente em: grupo I, participante das atividades educativas, e grupo II, que seguiu a rotina de atendimento. Os hipertensos do grupo I realizaram MRPA no início e final do estudo. Efeito do avental branco foi avaliado pela diferença entre a medida casual e MRPA. Foram incluídos 290 hipertensos, porém realizaram MRPA 82 hipertensos. Houve aumento no controle da pressão do início ao final do estudo nos hipertensos do grupo I (p < 0,05) avaliado pela MRPA (60% para 68,3%) e pela medida casual (62% para 71%); no grupo II o controle foi maior na MRPA do que na medida casual (63% vs 50%). O efeito do avental branco foi maior no grupo II. Original article AbStRActA randomized comparative study was performed to evaluate the control of hypertension with use of home blood pressure measurement (HBPM) and casual blood pressure measurement, and analyze the white coat effect. Hypertensive patients in primary health care units were randomly divided into two groups: group I, participating of the educational activities and group II that followed the routine treatment. The hypertensive patients from group I realized HBPM at the beginning and the end of the study. White-coat effect was evaluated by the difference between the casual blood pressure measurement and HBPM. The study included 290 hypertensive patients, but realized HBPM 82 hypertensive patients. There was increase in blood pressure control from the beginning to end of study in hypertensive patients from group I (p < 0.05) measured by HBP (60% to 68.3%) and casual measurement (62% to 71%) and in group II, HMBP hypertension control was higher than the casual blood pressure measurement (63% vs 50%). The white coat effect was greater in hipertensive patients from group II. RESUmENUn estudio comparativo aleatorizado se realizó para evaluar el control de la hipertensión con el uso de la medición de la presión arterial en el hogar y la medición ocasional de la presión arterial, y analizar el efecto de bata blanca. Los pacientes hipertensos en las unidades de atención primaria de salud fueron divididos aleatoriamente en dos grupos: grupo I, participando de las actividades educativas y el grupo II que siguieron el tratamiento de rutina. Los pacientes hipertensos del grupo I se dio cuenta de medición de la presión arterial en el hogar en el comienzo y el final del estudio. Blanco-capa efecto fue evaluado por la diferencia entre la medición de la presión arterial casual y medición de la presión arterial en el hogar. El estudio incluyó a 290 pacientes hipertensos, pero se dio cuenta de la medición de la presión arterial en el hogar 82 pacientes hipertensos. Hubo un aumento en el control de la presión arterial desde el principio hasta el final del estudio en los pacientes hipertensos del grupo I (p...
Objective: To evaluate the conditions of sphygmomanometers in use at public and private hospitals. Methods: A descriptive study using a quantitative approach, undertaken in four major hospitals in the State of São Paulo, in the period between 2009 and 2010. The aneroid manometers were tested against a calibrated mercury manometer. They were considered out of calibration when the differences were ≥ 4 mmHg. Results: We assessed 162 sphygmomanometers (78 in a public hospital and 84 from philanthropic and private institutions) and 98.1% were of the aneroid type. It was verified that 56.2% of the manometers were not calibrated (48.6% of private hospitals and 63.1% of public hospitals). Analyzing the mean differences of negative decalibration, there was a significant difference between the manometers of the private hospital and the public hospitals (-6.14 ± 2.66 mmHg vs. -8.97 ± 6.74 mmHg, respectively, p <0.05). It was also observed that in 70.2% there was no periodic evaluation made, 26.7% had aged rubber extension, 20.5% presented leaking valves, and 27% of the manometers did not rest with the pointer on the zero mark. Conclusion:The decalibration of the aneroid sphygmomanometers was significant and may lead to incorrect evaluation of blood pressure. Keywords: Sphygmomanometers; Blood pressure determination/instrumentation; Equipment failure; Evaluation studies as topic; Hospital services RESumoObjetivo: Avaliar as condições de uso dos esfigmomanômetros em hospitais públicos e privados. Métodos: Estudo descritivo de abordagem quantitativa realizado em quatro hospitais de grande porte do Estado de São Paulo, no período entre 2009 e 2010. Os manômetros aneroides foram testados contra manômetro de mercúrio calibrado. Foram considerados descalibrados quando as diferenças foram ≥ a 4 mmHg. Resultados: Foram avaliados 162 esfigmomanômetros, (78 de um hospital público e 84 de instituições filantrópicas e privada) e 98,1% eram do tipo aneróide. Verificou-se que 56,2% dos manômetros estavam descalibrados (48,6% do hospital privado e 63,1% dos hospitais públicos). Analisando-se as médias das diferenças negativas da descalibração, houve diferença significativa entre os manômetros do hospital privado e os dos hospitais públicos 14±2,97±6,74 mmHg, respectivamente, p<0,05). Observou-se ainda que em 70,2% não era feita avaliação periódica; 26,7% tinham extensão de borracha envelhecida; 20,5% das válvulas apresentaram vazamento; e 27% dos manômetros não estavam com o ponteiro na marca zero. Conclusão A descalibração dos esfigmomanômetros aneróides foi expressiva e pode acarretar avaliação incorreta da pressão arterial.
