Legislação de rotulagem nutricional: instrumento de informação na promoção de escolhas alimentares - Natal-RN

Resolutions of the Board of numbers 359 and 360, of December 23, 2003, relating to Nutrition Labelling for Packaged Foods, establish quality standards and provide the education activities for health consumption, since one of the factors that enable the selection of healthier foods are the food labels as an important part in nutrition education. This is a descriptive study with a cross-sectional design. To calculate sample size, it was considered a margin of error of 20%, confidence level of 95% and prevalence of 52.5% for verifying nutritional information in a pilot study conducted in 2007. A total of 145 subjects were interviewed, resulting in 371 consumers in Natal, Rio Grande do Norte, Brazil, in order to determine prevalence of consulting nutritional information contained on food labels as a nutritional guideline for consumers and its association with sociodemographic variables as well as identify the intervention measures suggested by intervieweds so that this information can be better used to select healthy foods. Twenty-five of the 69 supermarkets belonging to the Supermarket Association of Rio Grande do Norte (ASSURN) were randomly selected. Data collection relied on interviews and extensive direct observation, using a semi-structured form composed of eight closed questions, some of which were multiple choice, and ten open questions. The chi-square test was performed for statistical analysis, using Statistical Package for Social Sciences (SPSS) 15.0 software. Label information most consulted was: expiry date (91.6%); product brand (49.4%); nutritional information (47.0%); zero trans fat (32.9%); zero sugar content (12.8%); zero fat content (3.0%); rich in fibers (2.7%); whether light or diet (30.4%); list of ingredients (16.8%); whether the product contained gluten or not (4.1%). When asked about the importance of nutritional information, 96.8% of the subjects responded important or very important ; of these 46.6% and 3.8% reported partially or totally understanding the information presented. It was found that 41.6% of the consumers consulted nutritional information for dietary reasons related to nontransmissible chronic diseases and 35.7% to be able to choose healthier foods. The data show a significant association between motivation to choose healthier foods and higher family income and schooling (p<0.0001). The intervention measures mentioned to make nutritional information better understood and used were: information and orientation about nutritional information, provided by qualified professionals in the supermarkets, the commercial establishment or the product manufacturer (73.9%) and media disclosure about the nature, importance and purpose of nutritional information (42.9%). In despite of communication noises the consumers use the nutrition claim for the nutritional guidance, showing association with some demographic variables. However, they desire the implementation of intervention measures that can be contextualized in the political construction of nutrition education to promote healthy food choices

Efeito da utilização da levedura desidratada de álcool em dietas para tilápia-do-nilo

Este trabalho teve como objetivo avaliar o efeito da levedura desidratada de álcool (Saccharomyces cerevisae) como substituto do suplemento vitamínico, em dietas de tilápia-do-nilo (Oreochromis niloticus). Trezentos alevinos machos, sexualmente revertidos, com peso médio de 1,5 g, foram distribuídos igualmente em 20 aquários de fibra de vidro, equipados com filtro biológico. Cinco dietas isoprotéicas com 32% de proteína bruta na primeira fase (40 dias) e com 28% de proteína bruta na segunda fase (74 dias) foram fornecidas ad libitum, duas vezes ao dia. A dieta-controle não conti-nha levedura, e as demais apresentavam 10% de levedura. O delineamento foi inteiramente casualizado, com cinco tratamentos e quatro repetições. Não houve influência significativa dos tratamentos sobre o ganho de peso e taxa de crescimento específico. Foi observada, nos peixes alimentados com dietas sem suplemento vitamínico, alta mortalidade. Os peixes que receberam levedura apresentaram menor conteúdo corporal de proteína, e maior, de lipídeos. A levedura desidratada de álcool pode ser usada como fonte de vitaminas hidrossolúveis em dietas para alevinos de tilápia-do-nilo.

UTILIZAÇÃO da PRÓPOLIS E ÁLCOOL ETÍLICO NO CONTROLE DE Salmonella em RAÇÕES AVÍCOLAS

Em quatro experimentos foram avaliados como agentes antibacterianos os produtos própolis em solução alcoólica e álcool etílico, adicionados às rações artificialmente contaminadas com os respectivos sorotipos: Salmonella typhimurium Nalr - Specr, (resistentes ao ácido Nalidíxico e a Spectinomicina) nos três primeiros experimentos e Salmonella agona Nalr - Specr, Salmonella infantis Nalr - Specr e Salmonella enteritidis Nalr - Specr no quarto experimento. As rações foram fornecidas a grupos de 10-16 pintos de corte de um dia. em todos os experimentos os produtos testados foram adicionados na base de 2% da ração. Quando se utilizou solução hidroalcóolica de própolis (exp. 1), seguidas 120 horas após o desafio, detectou-se a presença da bactéria nos cecos. No segundo experimento, testou-se a solução de própolis e seu diluente, o álcool etílico; seguidas 96 horas após o desafio, não foi observada a presença da bactéria nos cecos (< 2,0 log10). Avaliou-se, no terceiro experimento, a ação da solução de própolis e do álcool etílico no tempo, adicionados na ração 14 dias e 28 dias antes do fornecimento às aves. Após 72 horas do desafio, a leitura nas placas acusou a presença da bactéria nos cecos. Dentro deste último período, também se avaliou a ação da própolis em pó (extrato seco) e esse mesmo extrato em uma solução aquosa, adicionados à ração 48 horas antes do fornecimento às aves sendo que os resultados confirmaram a presença da bactéria nos cecos. No quarto experimento avaliou-se somente o álcool etílico nas rações artificialmente contaminadas com os sorotipos S. agona, S. enteritidis e S. infantis, registrando-se contagem zero (<2,0 log10) apenas com o último sorotipo. Os resultados obtidos permitem concluir que o tratamento com a solução de própolis apresentou ação sobre a S. typhimurium somente quando em solução alcóolica, dentro de um período de 48 horas, indicando que o efeito bactericida se deveu ao álcool etílico presente na solução. A ação do tratamento com o álcool etílico sobre os demais sorotipos demonstrou resultado parcial sendo observado efeito bactericida nos sorotipos S. typhimurium e S. enteritidis artificialmente inoculados na ração.

Emergência e desenvolvimento de guanxuma (Sida rhombifolia), capim-braquiária (Brachiaria decumbens) e cana-de-açúcar (Saccharum spp.) influenciados por subprodutos da destilação do álcool

Este trabalho objetivou avaliar os efeitos da aplicação de óleo de fúsel, comparativamente a vinhaça e flegmaça, sobre o desenvolvimento e a composição química de plantas de guanxuma (Sida rhombifolia), capim-braquiária (Brachiaria decumbens) e cana-de-açúcar (variedade RB72454), cultivadas simultaneamente em casa de vegetação. As concentrações de 12,5; 25,0; 50,0; e 100,0% (v/v) de cada subproduto e a testemunha (água) foram aplicadas (numa taxa equivalente a 150 m³ ha-1) no solo dos vasos (22 L), contendo uma planta de cana-de-açúcar (13 cm de altura) e 100 sementes de cada planta daninha. O delineamento foi o inteiramente casualizado, com 13 tratamentos e 4 repetições, em esquema fatorial 3 x 4 (três tipos de resíduos e quatro concentrações), e uma testemunha adicional com água. O óleo de fúsel inibiu a emergência de Sida rhombifolia e Brachiaria decumbens e matou a cana-de-açúcar. A vinhaça e a flegmaça prejudicaram a emergência e o desenvolvimento de B. decumbens, bem como o de S. rhombifolia, mas não o da cana-de-açúcar.

Impactos da legislação ambiental brasileira na exportação de camarão: um estudo com exportadores de camarão do Rio Grande do Norte

Brazilian exportations come growing in a constant form in the last years, stimulated for the globalization and public politics directed toward the increase of the internal surplus. In this context the objective of this work was to investigate the perception of the shrimp exporting entrepreneurs of Rio Grande do Norte, with relation to the impact of the Brazilian environmental legislation in the companies competitiveness at the external market. From data collected from the controllers of the companies, it was used a survey methodology, with exploratory and descriptive character. The results found in this study indicate that the companies, in general way, understand that the environmental legal requirements do not confuse nor help in the search and conquest of new international markets. A little more of the half of the researched companies, does not see the legislation rigid as important factor of competitiveness. However a sufficiently significant percentage, already has a more strategical vision on the subject, or at least already it heard to speak on such possibility

Análise estatística das emissões de CO e HC produzidas por gases da exaustão veicular oriundos de gasolina, GNV e mistura álcool/gasolina

The vehicles are the main mobile sources of carbon monoxide (CO) and unburned hydrocarbons (HC) released into the atmosphere. In the last years the increment of the fleet of vehicles in the municipal district of Natal-RN it is contributing to the increase of the emissions of those pollutants. The study consisted of a statistical analysis of the emissions of CO and HC of a composed sample for 384 vehicles with mechanization Gasoline/CNG or Alcohol/Gasoline/CNG of the municipal district of Natal-RN. The tests were accomplished in vehicles submitted to Vehicular Safety's Inspection, in the facilities of INSPETRANS, Organism of Vehicular Inspection. An partial gases analyzer allowed to measure, for each vehicle, the levels of CO and HC in two conditions of rotation of the motor (900 and 2500 rpm). The statistical analysis accomplished through the STATISTICA software revealed a sensitive reduction in the efficiency of the converters catalytic after 6 years of use with emission average it is of 0,78% of CO and 156 (ppm) of HC, Which represents approximately 4 (four) times the amount of CO and the double of HC in comparison with the newest vehicles. The result of a Student s t-test, suggests strongly that the average of the emissions of HC (152 ppm), at 900 rpm, is 40% larger than at 2500 rpm, for the motor without load. This result reveals that the efficiency of the catalytic conversion is limited kinetically in low engine speeds. The Study also ends that when comparing the emissions of CO and HC considering the influence of the fuels, it was verified that although the emissions of CO starting from CNG are 62% smaller than arising from the gasoline, there are not significant differences among the emissions of HC originating from of CNG and of the gasoline. In synthesis, the results place the current criteria of vehicular inspection, for exhaust gases, in doubt, leading the creation of emission limits of pollutant more rigorous, because the efficiency of the converters catalytic is sensibly reduced starting from 6 years of use. It is also raised the possibility of modifications in the test conditions adopted by the current norms, specifically in the speed engine, have seen that in the condition without load the largest emission indexes were registered in slow march. That fact that allows to suggest the dismissal of the tests in high speed engine, reducing the time of inspection in half and generating economy of fuel

Desenvolvimento de nanocompósito (hidroxiapatita/ poliuretano) pela gelação (gelling) de poli ( álcool vinílico) (PVA) para remoção de metais pesados

Removing microcontaminants from effluents is a challenge today, because of its high cost and low efficiency, especially in the treatment of effluents containing heavy metals. An alternative that has emerged is the use of biodegradable nanocomposites, which exhibit good removal and recovery performances, in addition to its low cost. With this in mind, the present study aimed to develop and characterize a nanocomposite based on hydroxyapatite (HAP), polyurethane (PU) and polyvinyl alcohol (PVA) for removing heavy metals. Thus, the research was conducted in several steps: i)- Physico-chemical and microbiological hospital effluent characterization; ii)- Production of hydroxyapatite by aqueous precipitation technique, and their characterization; iii)- Production of the nanocomposite in which the hydroxyapatite was added to the polyurethane prepolymers and then the polyvinyl alcohol/hydroxyapatite film was produced; iv)- Polyvinyl composite without film PU/HAp was also produced in the proportions of 20 and 40% HAp; v)- The composites was characterized by the techniques of XRD, FTIR, SEM / EDS, BET, Zeta Potential and TGA; vi)- The sisal and coconut fibres were washed and dried for comparative tests of adsorption; vii)- Adsorption tests for evaluating the removal of heavy metals (nickel and cadmium). Initial screening adsorption capacity (HAp; PU/HAp - 20 and 40%; PU / HAp / PVA), kinetic studies of adsorption of Cd (II) by HAp; multifactorial design analysis (factorial design) for identifying the most important variables in the adsorption of Cd (II) by composite PU/HAp. Also comparative analysis of adsorption of Cd and Ni by composite PU/HAp were conducted, as well as comparative tests of adsorption of Cd (coconut fibre) and Ni (sisal fibre). It was possible to verify that the composite PU/HAp 40% showed better effectiveness for the removal of Cd (II) and Ni (II), above 80%, equivalent to the lignocellulosic fibre used and HAp produced. As main conclusion, it can be referred that the composite PU/HAp 40% is an effective adsorvent to wastewater treatment for heavy metal removal, with low cost and high efficiency

Análise das emissões atmosféricas por veículos automotores em Natal-RN

The fast urban occupation of Brazil, mainly from the last decade of 50, a sensible degradation of the quality of the air generated mainly for the activities was verified human beings associates to industrialization. From the past years, the situation has gotten worst in function of the increment of the fleet of vehicles in circulation in the great cities. Being these, in the city of Natal-RN, the ones that offer the biggest contributions to the atmospheric pollution. For atmospheric air to be a finite natural resources, indispensable and essential to the maintenance of the life in the land, is necessary to the implementation of action to improve its quality and to protect the health of the population. With the objective to study relative aspects to the characteristics of vehicles in use, the present study it searchs to analyze the levels of emissions of gases generated for vehicles converted bi-fuels into the modalities: natural gas (GNV), gasoline and alcohol, inspected for ends of register and together licensing to the State Department of Transit. One used the data gotten from inspections carried through for the company System Specialized in Inspection To propagate, in the city of the Natal-RN, capital of the State of Rio Grande do Norte, between 14 of November of 2003 and 30 of December of 2004. The analyzed parameters are established in the resolution nº 07/93 CONAMA. Of a total of 1.517 inspected vehicles, a average of 15,2% of failed was gotten, or either, that they emit levels of pollution above of the limits established for the legislation, below of the national average that is of 20,0%. The analysis of the data discloses that 7.3% of the fleet are converted the GNV; the growth of vehicles converted the GNV into the city is gradual, with a average of increment in last the 4 years of 23,3%; it has a vehicle predominance that has as combustible original to the gasoline (88,2%); the inspected fleet has average age of 8 years of use, considered young for the Brazilian standards, except for the moved one to the alcohol (average of use of 15 years). Moreover, the type of fuel is not the main parameter to define the indices of emissions; the age of the fleet is the parameter most important when emission is analyzed to propagate; the gas that more generates failed in the inspections is the corrected carbon monoxide; the vehicles generate higher indices of emissions in idling for all the fuels; the presence of the catalyser was not reflected, as it expected, in the reduction of emissions of gases toxic, however when analyzed according to year of manufacture, it was observed that for the vehicles manufactured between 1997 and 2004, reduction of 46,0% in the failed of the vehicles equipped with catalyser was gotten. In conclusion, the fleet of the studied sample, in average terms, takes care of to the requirements of Resolution CONAMA nº 07/93. The results gotten for the present study can subsidize action of public administrations that aim at to the improvement and the maintenance of the quality of air in the city of Natal-RN, as, for example, to implant a net of monitoramento of the quality of air

Estudo do equilíbrio líquido-vapor do sistema água+etanol+líquido iônico visando a separação do álcool anidro

Anhydrous ethanol is used in chemical, pharmaceutical and fuel industries. However, current processes for obtaining it involve high cost, high energy demand and use of toxic and pollutant solvents. This problem occurs due to the formation of an azeotropic mixture of ethanol + water, which does not allow the complete separation by conventional methods such as simple distillation. As an alternative to currently used processes, this study proposes the use of ionic liquids as solvents in extractive distillation. These are organic salts which are liquids at low temperatures (under 373,15 K). They exhibit characteristics such as low volatility (almost zero/ low vapor ), thermal stability and low corrosiveness, which make them interesting for applications such as catalysts and as entrainers. In this work, experimental data for the vapor pressure of pure ethanol and water in the pressure range of 20 to 101 kPa were obtained as well as for vapor-liquid equilibrium (VLE) of the system ethanol + water at atmospheric pressure; and equilibrium data of ethanol + water + 2-HDEAA (2- hydroxydiethanolamine acetate) at strategic points in the diagram. The device used for these experiments was the Fischer ebulliometer, together with density measurements to determine phase compositions. The experimental data were consistent with literature data and presented thermodynamic consistency, thus the methodology was properly validated. The results were favorable, with the increase of ethanol concentration in the vapor phase, but the increase was not shown to be pronounced. The predictive model COSMO-SAC (COnductor-like Screening MOdels Segment Activity Coefficient) proposed by Lin & Sandler (2002) was studied for calculations to predict vapor-liquid equilibrium of systems ethanol + water + ionic liquids at atmospheric pressure. This is an alternative for predicting phase equilibrium, especially for substances of recent interest, such as ionic liquids. This is so because no experimental data nor any parameters of functional groups (as in the UNIFAC method) are needed

Administração experimental de esteróide anabólico androgênico e álcool causa alterações histológicas e morfométricas nos ovários e útero de ratas adultas

Abusive and indiscriminate use of androgenic anabolic steroid is an usual practice among youth and adults of both sex. Usually these substances were utilized simultaneously with others drugs, licit or not, that causes damage to health. The purpose of study was to evaluate the influence of experimental administration of nandrolone decanoate steroid (ND), associated or not to alcohol, in the ovaries and uterus of adult rats. Females with regular estrous cycle (n = 20), were distributed in the groups: a) control (physiological solution); b) ND (7.5 mg/kg BW; intraperitoneal); c) alcohol (0.2 mL/100g BW; oral); d) ND + AL. The teatments were realized by single dose per week, during twelve consecutive weeks. The ovaries of rats in the groups ND, AL and ND + AL presented intense follicular atresia and decrease in the number of antral follicles and corpora lutea. None treatment did affect ovarian weight, but uterine weight was increase (p<0.05) in the ND + AL group. There were alterations in the uterine histology and morphometry at function of each treatment. Isolated or simultaneous use of anabolic steroid and alcohol promotes ovarian and uterine toxicity in adult female rats.

Aspectos dinâmicos da água versus álcool e acetona por técnicas de congelamento

Water still represents, on its critical properties and phase transitions, a problem of current scientific interest, as a consequence of the countless open questions and of the inadequacy of the existent theoretical models, mainly related to the different solid and liquid phases that this substance possesses. For example, there are 13 known crystalline forms of water, and also amorphous phases. One of them, the amorphous ice of very high density (VHDA), was just recently observed. Other example is the anomalous behavior in the macroscopic density, which presents a maximum at the temperature of 277 K. In order to experimentally investigate the behavior of one of the liquid-solid phase transitions, the anomaly in its density and also the metastability, we used three different cooling techniques and, as comparison systems, we made use of the solvents: acetone and ethyl alcohol. The first studied cooling system employ a Peltier plate, a device recently developed, which makes use of small cubes made up of semiconductors to change heat among two surfaces; the second system is a commercial refrigerator, similar to the residential ones. Finally, the liquid nitrogen technique, which is used to refrigerate the samples in a container, in two ways: a very fast and other one, almost static. In those three systems, three Beckers of aluminum were used (with a volume of 80 ml, each), containing water, alcohol and acetone. They were closed and maintained at atmospheric pressure. Inside of each Becker were installed three thermocouples, disposed along the vertical axis of the Beckers, one close to the inferior surface, other to the medium level and the last one close the superior surface. A system of data acquisition was built via virtual instrumentation using as a central equipment a Data-Acquisition board. The temperature data were collected by the three thermocouples in the three Beckers, simultaneously, in function of freezing time. We will present the behavior of temperature versus freezing time for the three substances. The results show the characterization of the transitions of the liquid

Álcool e comportamento: efeitos na aprendizagem e memória

Excessive alcohol consumption is responsible for many harmful effects on individuals and society. Despite years of research, the mechanisms by which alcohol affects neurological functions and the exact causes of cognitive impairment related to long-term use are unknown. In this sense, this master study proposed to observe how different doses of alcohol affect the addiction response and the learning ability of two fish species: Betta splendens and Danio rerio, the latter a commonly model due to organizational and functional characteristics shared with mammals. For this, different concentrations of ethanol (0%, 0.1%, 0.25%, 1% and 1.5%) were used in acute, chronic and withdrawal treatments. We tested the fish in three experimental protocols: 1) alcohol addiction potential using conditioned place preference, 2) associative conditioning using light as unconditioned stimulus and food as conditioned stimulus and 3) spatial learning using a maze without cues. For the alcohol addiction potential, preference between two different places in a shuttle box was tested before and after alcohol exposure (chronic and acute). In this test, the animals intoxicated by 0.1% did not change behavior, while animals receiving 1% and 1.5% alcohol changed the initial preference to the side where they received alcohol For the associative conditioning, the results show that the groups undergoing low dose (0.1%), both in chronic and withdrawal treatment, learned the task faster than control; groups under 0.25 and 1% alcohol withdrawal learned the task after control; groups chronically intoxicated with these doses did not learn the task. For the spatial learning test, fish submitted to acute and chronic treatments decreased the time to exit the maze; there were significant differences in the animal s performance in a dose-dependent pattern. This difference was not observed for the withdrawal treatment. Given these results, we conclude that the effects of alcohol on learning are dependent on the dosage. Furthermore, low doses of alcohol seem to maximize animal performance on learning tasks and do not alter their seeking behavior, while higher doses induced addition and hinder learning

Álcool e sociabilidade: a farra das adolescentes

The experience as a school psychologist allowed me to notice that expressions like I was like trash in the gang s barbecue , and we chatted away, only the girls, and we all got drunk , are very common in conversations between Elementary and High School students, pointing out to a concerning incidence of alcohol consumption among female adolescents. However, studies about this theme haven t gone deep in the nowadays reality these girls are living in. This study aimed at comprehending the aspects of the relation between girls and alcohol, starting from the point that exaggerated consumption indicates introductory rituals for some groups, making social relations easier and becoming a sociability factor. To give this study some support, a questionnaire was applied to 1028 female teenagers, between 12 and 18 years old, students in private schools in Natal, capital of Rio Grande do Norte. The context chosen for the development of the study - private schools -, arose from the notion that the majority of the data collection carried out about alcohol and other psychotropic drugs aim at public school students. The instrument used was divided in two parts, one that treated about the first contact with alcohol (experimentation), and other that points to the current relation with alcoholic beverages, with 27 closed questions but nevertheless with available space for manifestation like if other; which?, applied collectively in classrooms. The data received a statistic treatment from SPSS and showed that the first contact with alcoholic beverage happens in domestic environment, having parents and friends as companions, very precociously, around 10 years of age, as curiosity. At this moment, Ice drink is the most consumed beverage. The main reason that leads them to drink is to pass the time in parties, and they don t drink alone (93% of students researched), what gives alcohol this recreational and socializing characteristic. They do consider alcohol a kind of drug, but are not afraid of getting addicted. People that drink usually show to be extroverted, they get happier (40,3%) and are not shy at all (29,4%), have attitudes of moral character, like to get involved with unknown boys (18,5%), get numb (9,9%), or get sad (1,9%). They label as vulgar the girls that drink, depending on the amount, and to be stimulated by the boys to drink. The study shows that systematic interventions of the school are necessary, once it is an institution that should care about education and personality traits of children and adolescents, as well as the important role of the psychologist in this context. Besides, it claims the society to get effectively involved with the public policies that already exist

A redução de danos no atendimento especializado em álcool e outras drogas

The harm reduction HR is the official policy of Ministry of Public Health to deal with problem derived from alcohol consumption and other drugs AD. The HR refers to policies and support programs whose purpose is to reduce the risks related to the use of AD, without necessarily decrease individual consumption. This research aim was to analyze the HR conceptions and practices at two specialized institutions for AD users: 1) Psychosocial Care Center Alcohol and Drugs III (CAPSad III); 2) Therapeutic Community Fazenda da Esperança (FE) Dom Bosco. This is a qualitative research that used the following methodological tools: semi-structured interview with 21 professionals; socio demographic file and rounds of conversation with 63 participants users; participant observation and field journal. The interviews with professionals have characterized HR as a less complex and cheap treatment. At FE the HR proposal does not make part of their actions, being considered ―against the human being dignity‖. At CAPSad III is understood as an ―inevitable‖ guideline to service, once users do not remain abstinent. The users understand RD as an improvement in healthy conditions, social relations and work that occurs with the decreasing consumption of AD. They use the HR when they avoid situations that facilitate AD consumption, share relapse prevention strategies and, exclusively at CAPSad III, decrease psychotropic consumption. Stands out as an analyzer the HR comprehension as a less efficient treatment that opposes to the objective of both institutions, which is abstinence. The HR is not operationalize in daily routine by professionals and users as a healthy promotion strategy, however, the users are more affected to HR and produce strategies to face the difficulties arising from the AD consumption

Suporte ao uso de álcool e drogas na atenção primária: um estudo com equipes de Natal/RN

National surveys indicate that 6.8 % of the brazilian population is dependent on alcohol and 1 % dependent on illicit drugs, representing a significant portion of the population affected by this issue . Primary Care becomes instrumental in expanding the coverage of this demand and in reducing unnecessary referrals for specialized care. This study aimed to investigate the responsiveness and institutional support of Primary Care Teams in relation to the demands of alcohol and drugs users. The research was conducted in a Family Health Unit in West Sanitary District of Natal City. With quantitative and qualitative nature, our study consisted of two stages. At first, we performed a mapping of alcohol and other drugs abusive use in a sample of the population assisted by Family Heath Teams, using sociodemographic questionnaire and ASSIST (Alcohol, Smoking and Substance Involvement Screening Test). 406 questionnaires were completed. Of these questionnaires, 27.8% are men and 72.2% women, of which 56% are between 20 and 39 years-old, they are housewives, have a stable relationship and are consumers of tobacco (37.6%), marijuana (13%) and especially alcohol (57%). In second stage, two Conversation Circles with Family Health Teams and the referential Family Health Support Center were formed to discuss the data of the mapping realized in the previous phase. The circles, which had participation of 20 of the 37 professional teams from Family Health and 2 from Family Health Support Center, showed a lack of professional training in the subject; inability of the healthcare network in the user embracement; belief of professionals that nothing can be done when matter is alcohol and drugs; and referencing as the only care action performed by teams. Thus we point out the need to support an approach on issues of alcohol and drugs which consider gender issues, investing in Harm Reduction Policy as a possibility of working in this context for recognizing each user in their uniqueness and strategizing with them to promote health in a broad and contextualized way
