INVESTIMENTOS PÚBLICOS E PRIVADOS NAS CIDADES MÉDIAS BRASILEIRAS E REPERCUSSÕES NA MOBILIDADE ESPACIAL DA POPULAÇÃO: O EXEMPLO DE VITÓRIA DA CONQUISTA/BAHIA- 1970 A 2015

This paper presents an analysis of the dynamics of the regional population and migration in medium-sized cities, based on the Vitória da Conquista example, as a result of public policies implemented in these cities and of the growth of private investments, due to the expansion of consumer market. The analysis in Vitória da Conquista was empirical and based on literature. In Vitoria da Conquista interviews were made with people born in other municipalities. Interviews were also made with city residents and residents of other municipalities in large hospitals, higher education institutions, state and federal agencies in neighborhoods served by housing programs. The defined sample was 220 migrants of the region. The presence of population of regional origin in the medium-sized cities has intensified, as well as the arrival of migrants from other regions, mainly in search of higher education. In medium-sized cities located in areas with high social and economic inequalities, as in Vitória da Conquista, the search for hospital care, education and attendance in government offices with centralized activities, has been recurrent. This extends the presence of the region´s population in the city and promotes dynamism that attracts migrants from other regions in search of work and private entrepreneurs of national and international capital, with repercussions on intra-urban space.Esse trabalho traz uma análise sobre a dinâmica da população regional e migrante nas cidades médias, com base no exemplo de Vitória da Conquista, como resultado de políticas públicas implementadas no processo de constituição dessas cidades e do crescimento dos investimentos privados, em função da ampliação do mercado consumidor. A investigação em Vitória da Conquista, foi empírico-bibliográfica. Foram aplicadas entrevistas semi-estruturadas em Vitória da Conquista, com pessoas nascidas em outros municípios, residentes na cidade e residentes de outros municípios, em hospitais de grande porte, instituições de ensino superior, órgãos públicos estaduais e federais e em bairros atendidos pelos programas habitacionais. A amostra definida foi de 220 migrantes da região. A presença da população de origem regional nas cidades médias tem se intensificado, assim como a chegada de migrantes de outras regiões, principalmente em busca de ensino superior. Nas cidades médias localizadas em regiões com grandes desigualdades sociais e econômicas, como em Vitória da Conquista-BA, a busca por atendimento médico-hospitalar e atendimento em órgãos públicos com atividades centralizadas, tem sido recorrente, o que amplia a presença da população da região de influência na cidade, promovendo o dinamismo que atrai migrantes de fora da região em busca de trabalho e empreendedores privados de capital nacional e internacional, com repercussões no espaço intra-urbano

Prevention of hypertension in patients with pre-hypertension: protocol for the PREVER-prevention trial

<p>Abstract</p> <p>Background</p> <p>Blood pressure (BP) within pre-hypertensive levels confers higher cardiovascular risk and is an intermediate stage for full hypertension, which develops in an annual rate of 7 out of 100 individuals with 40 to 50 years of age. Non-drug interventions to prevent hypertension have had low effectiveness. In individuals with previous cardiovascular disease or diabetes, the use of BP-lowering agents reduces the incidence of major cardiovascular events. In the absence of higher baseline risk, the use of BP agents reduces the incidence of hypertension. The PREVER-prevention trial aims to investigate the efficacy, safety and feasibility of a population-based intervention to prevent the incidence of hypertension and the development of target-organ damage.</p> <p>Methods</p> <p>This is a randomized, double-blind, placebo-controlled clinical trial, with participants aged 30 to 70 years, with pre-hypertension. The trial arms will be chlorthalidone 12.5 mg plus amiloride 2.5 mg or identical placebo. The primary outcomes will be the incidence of hypertension, adverse events and development or worsening of microalbuminuria and of left ventricular hypertrophy in the EKG. The secondary outcomes will be fatal or non-fatal cardiovascular events: myocardial infarction, stroke, heart failure, evidence of new sub-clinical atherosclerosis, and sudden death. The study will last 18 months. The sample size was calculated on the basis of an incidence of hypertension of 14% in the control group, a size effect of 40%, power of 85% and P alpha of 5%, resulting in 625 participants per group. The project was approved by the Ethics committee of each participating institution.</p> <p>Discussion</p> <p>The early use of blood pressure-lowering drugs, particularly diuretics, which act on the main mechanism of blood pressure rising with age, may prevent cardiovascular events and the incidence of hypertension in individuals with hypertension. If this intervention shows to be effective and safe in a population-based perspective, it could be the basis for an innovative public health program to prevent hypertension in Brazil.</p> <p>Trial Registration</p> <p>Clinical Trials <a href="http://www.clinicaltrials.gov/ct2/show/NCT00970931">NCT00970931</a>.</p
