New research will map diseases and health risk factors

Begins on Monday (12) the collection of data for the National Health Survey (PNS), an unprecedented study conducted by the Ministry of Health in partnership with the Brazilian Institute of Geography and Statistics (IBGE). The research, which will be based on laboratory tests to assess the health of the Brazilian population, will map several diseases and health risk factors, such as hypertension, diabetes and obesity.

In addition to the questionnaires, blood and urine collection, anthropometric measurementand blood pressure measurement scans will also be included in this study. The collection of clinical samples will be done by professionals linked to the Sírio Libanês hospital, while the interviews will be conducted by IBGE researchers who have been in training since the end of July.

The research begins in the states of São Paulo, Mato Grosso do Sul, Goiás, Rondônia, Roraima, Amapá and Rio Grande do Sul and, in the coming weeks, will reach all units of the federation. About 20,000 people are expected to undergo the tests, of the 80,000 households surveyed, in 1,600 Brazilian municipalities. The PNS will involve approximately 1,000 IBGE agents.

In total, the Ministry of Health will pass on R 15 million allocated to the research institute and R$ 6 million to the hospital that will be in charge of laboratory tests. The analyses made by the research will also diagnose whether the person diabetes, sickle cell anemia and analyze percentages of creatinine, potassium and sodium – indicators that may reveal possible health problems of the patient. If the results of the tests indicate any health problem, the interviewee will be referred to a health unit to receive medical follow-up.

DENGUE FEVER– The blood test will also provide information on the percentage of the Brazilian population that has already come into contact with thedengue virus. “Serology is important to support, in the future, the implementation of the vaccine counts dengue in the country, enabling the mapping of areas susceptible to outbreaks of subtypes of the disease.”, said the secretary of health surveillance, Jarbas Barbosa.

The material collected in the research will be stored and will make up a human serum bank to monitor the disease in the country, making it available to universities and research institutes. Secretary Jarbas Barbosa explains that the research will allow a broader evaluation and better planning of strategic actions and public policies. “In addition to allowing us to examine the brazilian health trend in the last decade, the PNS brings a very detailed x-ray not only of Brazil, but of regions, states, capital and interior,” he notes. According to him, the study is expected to be conducted every five years. The first results of this study should be published in 2014.

The research is part of the Plan to Combat Chronic Noncommunicable Diseases (NCD) and aims to produce new information on eating habits, smoking, alcohol use, physical activity practice and factors associated with unhealthy behaviors of the population. The information will support actions to combat NCDs, which account for 72% of deaths in Brazil.

The initiative proposes that the PNS continue the surveys of the National Plan for Home Sample (PNAD), conducted in 1998, 2003 and 2008. The PNS should also outline the lipid profile of the population and size access to the diagnosis of some chronic diseases (such as hypertension, diabetes, hypercholesterolemia, creatinine in the blood, salt dosage in the urine), based on the comparison of objective measures (anthropometric, blood pressure and laboratory tests) and subjective (self-reported morbidity), in addition to other investigations. The PNS was approved by the National Research Ethics Commission (Conep).

HISTORIC– Since 2009, the Ministry of Health has been meeting with researchers to begin the preparation of the research. From 2010 to 2011, there were regular meetings with IBGE representatives, where national and international experiences were studied; methodology is defined; sampling and other important points. In 2012, questionnaires and the partnership with the Syrian-Lebanese Hospital for laboratory tests were closed.

The Ministry of Health already conducts, annually, the Vigitel (Surveillance of Risk and Protective Factors for Chronic Diseases by Telephone Survey), a study done by telephone survey in 26 states and the Federal District. In 2011, Vigitel interviewed 54,000 people, being an important source for the development of public preventive health policies. The National Health Survey, therefore, will serve as an ally to aggregate statistical information of the population’s life habits proven through the exams.
