Innumerable studies have focused been reported on the sleep spindles (SS), Sharp Vertex Waves (SVW) and REM, NREM Sleep as indicators interpreting EEG patterns in children. However, Frequency and Amplitud Gradient (FAG) is rarely cited sleep parameter in children,that occurs during NREM Sleep. It was first described by Slater and Torres, in 1979, but has not been routinely evaluated in EEG reports. The aim of this study was to assess the absence of SS, SVW and FAG, as an indication of neurological compromise in children. The sample consisted of 1014 EEGs of children referred to the Clinical Neurophysiology Laboratory, Hospital Universitário de Brasília (HUB), from January 1997 to March 2003, with ages ranging from 3 months to 12 years old, obtained in spontaneous sleep or induced by choral hydrate. The study was transversal and analytical, in which, visual analysis of EEG traces was perfumed individually and independently by two electroencephalographers without prior knowledge of the EEG study or neurological findings. After EEG selection, the investigators analyzed the medical reports in order to define and correlate neurological pattern was classified according to the presence or absence of neurological compromise, as Normal Neurological Pattern (NNP), and Altered Neurological Pattern (ANP) respectively. From the visual analysis of the EEG(s), it was possible to characterize 6 parameters: 1- FAG present (64,1%); 2- FAG absent (35,9%); 3 - normal SS (87,9%); 4 - altered SS s (12,1%); 5 - normal SVW s (95,7%); 6 - altered SVW s (4,3%). The prevalence of well-formed FAG is found in the 3 months to 5 years age group in the children with NNF. FAG was totally absent from the age of 10 years. When comparing the three sleep graphielements, it was observed that SVW and SS were predominant in children with NNF. However, FAG absent was more prevalent in the ANF than in altered SS an SVW. The statistical analysis showed that there is a strong association of FAG absent, with isolated alteration, in ANF patients, in that the prevalence ratio was 6,60. The association becomes stronger when FAG absent + altered SS(s) is considered (RP= 6,68). Chi-square test, corrected by Yates technique, showed a highly significant relation for FAG ρ= 0,00000001, for error X of 5%, or else the 95% confidence interval (ρ<0,05). Thus, the FAG absent were more expressive in ANF patient than altered SS(s) and SVW(s). The association becomes stronger in order to establish a prognostic relation, when the FAG is combined with the SS. The results os this study allow us to affirm that the FAG, when absent at ages ranging from 3 months to 5 years , is an indication of neurological compromise. FAG is an age-dependent EEG parameter and incorporated systematically, in the interpretation criteria of the EEG of children s sleep, not only in the maturational point of view, but also neurological disturbances with encephalic compromise

To determine whether there is familiar aggregation of severe preeclampsia in a Brazilian population from Rio Grande do Norte and to characterize the maternal and perinatal outcomes in the studied population. Methods: A case control study was performed with 412 participants who were admitted at Maternidade Escola Januário Cicco (MEJC) for medical care. Of these, 264 subjects presented normal blood pressure and 148 were cases. Cases were composed of eclampsia (n=47), HELLP Syndrome (n=85) and Eclampsia associated with HELLP syndrome (n=16). The diagnosis of these illness were based on the citeria developed by National High Blood Pressure Education Program Working (2000). An interview was performed with each subject and questions related to personal and familiar history of hypertension, preeclampsia, HELLP syndrome and eclampsia. Statistical analysis was performed and comparison of median and mean between cases and controls were performed, with the level of significance of 5%. The Odds-Ratio was determined to estimate the risk of preeclampsia within the families. Results: There were no difference in the demographic data between cases and controls. Previous history of chronic hypertension and preeclampsia was more frequent in the case group. Headaches were more frequent in eclampsia and epigastric pain in the HELLP syndrome cases. Bleeding and oliguria were more frequently found in the eclampsia associated with HELLP syndrome cases. Acute Renal insufficiency was a common complication in the case group, but these cases did not evolve to chronic renal insufficiency. The maternal mortality was 0.4% and the perinatal mortality was high, 223 per 1,000 live births. The 111 risk of a woman to develop preeclampsia whose mother has hypertension or had preeclampsia was respectively 2.5 and 3.5. This risk was increased 5 times, when a sibling has hypertension and 6 times when both sibling and mother had previous history of preeclampsia. Conclusions: This study confirms that there is familiar aggregation of preeclampsia in this Brazilian population. The potential for cardiovascular complications due to development of chronic hypertension indicates the need of closely follow up of women who develop preeclampsia

The aim of this study was to learn about the social representations of the care provided by the Family Health Program (FHP) in the city of Natal, Brazil and determine how these representations guide the daily actions of doctors, dentists, nurses, nurse s assistants and oral health assistants during the work process. In this sense, we used the theoreticalmethodological approach to the Theory of Social Representations. For data collection, we used the following instruments: a two-part questionnaire, where the first part recorded sociodemographic data and the second part was adapted to the free word association technique (FWAT), which was applied to 90 professionals belonging to 18 FHP units. Interviews were also used as collection instruments. These were based on inductive stimuli and on direct observations of 30 of these professionals. After a superficial reading of the material, we constructed a corpus from which ten categories emerged. To analyze FWAT we used lexicographic analysis, combining frequency and the mean order of responses. The interviews and sociodemographic variables were analyzed using content analysis and descriptive statistical analysis, respectively. The study showed that the central nucleus of the social representation in question is composed of the elements attention, receptivity and love, revealing that the subjects have different understandings of the FHP care process and that the knowledge accumulated in this respect is supported by an approximate vision of the meaning of care. However, traditional elements with trivializing connotations about care predominate, which compromises the development of strategies to overcome traditional practices. In the set of analyses, we were able to capture the invariance of a contradiction: on one hand, professionals know and affirm the importance of providing care for FHP patients; on the other, the experience of daily practice translates into the negation of this concept. In this contradictory context, professionals build gradual and successive syntheses that allow them to act and affirm themselves by associating information from their academic formation, structured knowledge acquired in other experiences, values and symbols of their daily routine. Thus, they shape and reshape themselves, according to what is concretely and specifically required, at the same time both plural and multiple. The composition of the central nucleus indicates that any measure that intends to modify attitudes that is, the daily actions of FHP professionals with respect to care must take into account and give priority to the debate about the redefining of the semantic fields of the central nucleus (love/attention/receptivity and humanization), especially those of love and attention

Fibromyalgia (FM) is a chronic rheumatic syndrome characterized by diffuse muscle-skeletal pain, and aerobic exercises represent a fundamental portion in therapeutic approach. Objective of this study was to evaluate the effectiveness of aerobic exercises accomplished in the water of the sea (thalassotherapy) for women with FM and to compare with exercises accomplished in the swimming pool, involving a multidisciplinary team, composed by rheumatologists, physical therapists, students of physical therapy and students of physical education. Forty six (46) women with age between 18 and 60 years with FM were randomized in 2 groups: a swimming pool group (23 patients) and a sea group (23 patients). 80th groups trained a week with the same program of aerobic conditioning 3 times (60 minutes each) for 12 weeks. Ali the patients were evaluated, before and immediately after treatment, with Visual Analogical Scale (VAS) for pain and fatigue, number of tending points, Fibromyalgia Impact Ouestionnaire (FIO), Short Form 36 Health Survey (SF-36), Pittsburgh Sleep Ouality Index (PSOI) and Beck Oepression Inventory (BOI). For statistical analysis, it was used paired-t test for analysis intra-group and non-paired test for inter-groups analysis, significance levei of p <0,05. Four patients, of each group, didn't complete the training programo Groups were homogeneous and they were compared in initial evaluation, except for BOI (p <0,05). Both groups presented statistically significant improvement for ali appraised parameters in the post-treatment compared with initial evaluation, there were reduction of intensity of pain and fatigue, number of tending points, better functional capacity (FIO), life quality (SF-36), quality of sleep (PSQI) and depression indexes (BOI). However, in comparison among the groups, group of sea (thalassotherapy) presented better results for ali parameters, however with statistically significant difference just only for depression indexes (BOI). At the end, it was observed that accomplishment of aerobic exercises in sea water or swimming pool was effective as part of treatment for patients with FM. However, exercise programs with thalassotherapy seems to bring more benefits, mainly related to emotional aspects, could be a therapeutic option of low cost for patients with FM in our area

BACKGROUND: Polycystic ovary syndrame (PCOS) has been shown to cause a reduction in quality of life. Little is known on the psychosocial aspects associated with PCOS, especially on women s own experiences regarding the syndrome. Therefore, the aim of this study was to analyze the psychosocial impact of PCOS by measuring the health-related quality of life and exploring the women s own experiences of PCOS. METHODS: A two-phase model of combination of quantitative and qualitative research approaches was conducted, a crass-sectional survey to pravide quantitative data on the quality of life and a qualitative approach to understand the women s experience in relation to the PC OS sympt?ms. For the first phase, 109 women with PC OS and 104 healthy contrais were evaluated with the 36-item short-form health survey (SF-36). Additionally, semi-structured interviews (n=30) were conducted to facilitate in-depth exploration of PC OS women s experience. RESUL TS: PCOS patients showed significant reductions in almost ali SF-36 domains of quality of life when compared with healthy contrais (physical function 76.5:!:20.5 and 84.6:!:15.9, respectively; physical rale function 56.4:!:43.3 and 72.6:!:33.3; general health 55.2:!:21.0 and 62.5:!:17.2; vitality 49.6:!:21.3 and 55.3:!:21.3; social function 55.3:!:32.4 and 66.2:!:26.7; emotional rale function 34.2:!:39.7 and 52.9:!:38.2; mental health 50.6:!:22.8 and 59.2:!:20.2). Thematic analysis revealed reports of feeling abnormal , sadness, afraid and anxiety. These feelings were related to four symptoms commonly experienced by women with PCOS: excess hair grawth; irregular or absent menstruation, infertility and obesity. CONCLUSIONS: Polycystic ovary syndrame impacts women both physically and psychosocially. Owing to this, women with PCOS need not only medical treatment for. the reproductive, esthetic and metabolic repercussions, but also the care of a multidisciplinary team, since PCOS is not just a physical condition, but also an important psychosocial problem that affects various aspects of a woman s life

Objetivo: Analisar as características sociodemográficas, ocupacionais e de saúde clínica/comportamental, e o impacto desses fatores na avaliação da qualidade de vida de professores da rede municipal de Natal/RN. Métodos: Estudo descritivo-analítico com corte transversal e amostra de 242 docentes. Foram utilizados os questionários Whoqol-breve e nórdico, além de questões referentes ao trabalho do Job Content Questionnaire (JCQ). Os dados foram submetidos à análise estatística com nível de significância p<0,05, sendo utilizada a regressão logística binária, para análise de fatores hierarquicamente agrupados. Resultados: O domínio físico apresentou maior comprometimento entre os professores com trabalho de alta exigência (p=0,043), com mais de 02 diagnósticos de doenças (p < 0,001), atividade física inadequada (p= 0,001) e com sintomas osteomusculares (p=0.025); o domínio psicológico entre os docentes com trabalho de alta exigência (p=0,043), com carga horária maior que 28 horas semanais (p=0,034), com mais de 02 doenças (p=0,012) e que praticavam atividade física inadequadamente (p< 0,001); o de relações sociais com tempo de trabalho inferior/igual a 18 anos (p=0,036) e que residiam em bairro diferente do que trabalhavam (p=0,027); e, por último, o domínio meio ambiente apresentou maior comprometimento entre os docentes com carga horária superior a 28 horas semanais (p=0,025), que exerciam a atividade com tempo inferior/igual a 18 anos (p=0,013) e com sintomas osteomusculares (p= 0,002). Conclusões: Os professores apresentaram uma avaliação comprometida da qualidade de vida e do seu estado de saúde, tendo as atividades laborais desenvolvidas por esse grupo de trabalhadores um impacto importante sobre os resultados demonstrados. Tais achados podem comprometer a efetivação da proposta das escolas promotora de saúde

A epilepsia cursa com diversas comorbidades e, entre elas, estão as alterações de linguagem, que levam a criança a problemas educacionais e sociais desfavoráveis. A etiologia das alterações de linguagem envolve aspectos orgânicos, cognitivos e sociais, ocorrendo, na maioria das vezes, uma interrelação entre todos esses fatores. A idade da primeira crise epiléptica, o tipo de epilepsia, o uso de drogas antiepilépticas e a intervenção medicamentosa em politerapia podem implicar na ocorrência dessas alterações em crianças. O objetivo dessa pesquisa foi verificar a ocorrência de alterações de linguagem em crianças pré-escolares e escolares com diagnóstico de epilepsia atendidas no setor de Neurologia Infantil do Hospital de Pediatria Professor Heriberto Ferreira Bezerra. Caracterizou-se como um estudo prospectivo e transversal realizado com 90 crianças com epilepsia, submetidas à avaliação fonoaudiológica de linguagem oral e de leitura e escrita e como pesquisa interdisciplinar uma vez que envolveu áreas como a Fonoaudiologia, a Neurologia e a Psicologia. Os critérios de inclusão foram: 1) diagnóstico inequívoco de epilepsia, segundo a definição da ILAE (2005), 2) idade de 3 aos 12 anos, 3) padrão neurológico e desenvolvimento neuropsicomotor normais; os de exclusão: 1) diagnóstico de epilepsia duvidoso, 2) padrão neurológico e desenvolvimento neuropsicomotor alterados, 3) crianças com patologias pediátricas associadas. Foram analisadas as seguintes variáveis: sexo, idade da primeira crise epiléptica, tipo de crise epiléptica, regime de tratamento, presença de crise epiléptica, frequência à escola, tipo de escola e repetência. A análise estatística centrou-se na análise descritiva; determinou-se a razão de chances (odds ratio), adotando-se um intervalo de confiança de 95%; e na aplicação do teste exato de Fisher, levando-se em consideração p<0,05. Portanto, no que se refere à presença de alterações de linguagem oral, pôdese observar que o início das crises epilépticas durante o período de aquisição e desenvolvimento da linguagem oral bem como o tratamento medicamentoso neste período podem interferir no desenvolvimento da linguagem devido à imaturidade do sistema nervoso central além dos aspectos socioambientais, uma vez que o estigma e as crenças errôneas interferem negativamente no processo interacional tão importante para a aquisição e desenvolvimento da linguagem, o que também repercute nas habilidades de leitura e escrita. Dessa forma percebe-se a importância da atuação de uma equipe interdisciplinar (Fonoaudiologia, Psicologia e Neurologia Infantil) no processo avaliativo e no acompanhamento dos pacientes com epilepsia, o que trará benefícios psicosocioafetivos no que se refere à reorganização da sua qualidade de vida e, consequentemente, de seus familiares.

O desvio gástrico em Y de Roux é a técnica cirúrgica mais utilizada no tratamento da obesidade mórbida. Esta operação reduz o volume do estômago e o comprimento do intestino delgado, gerando alterações estruturais e metabólicas que podem influenciar no resultado de exames cintilográficos de pacientes operados. Com o objetivo de avaliar a biodistribuição pós-operatória do pertecnetato de sódio (Na99mTc) em órgãos de ratos Wistar submetidos à técnica do bypass (desvio) gástrico em Y de Roux (BGYR), foram utilizados 12 ratos distribuídos aleatoriamente em grupo tratado (n=6), submetido à cirurgia do BGYR e o grupo controle (C; n=6). No 15º dia de pós-operatório foi administrado 0,1 mL via plexo orbital de Na99mTc aos animais dos dois grupos, com atividade radioativa média de 0,66MBq. Após 30 minutos, os ratos foram mortos e retirados fragmentos de tireóide, coração, pulmão, fígado, estômago, rim e fêmur. As amostras foram lavadas com solução salina 0,9%, pesadas e submetidas ao Contador Gama 1470, WizardTM Perkin-Elmer-Finlândia para determinação do percentual de atividade radioativa total por grama (%ATI/g) de cada órgão. Empregou-se o teste t de Student para análise estatística, considerando-se significantes as diferenças das médias quando p<0,05. Redução significante na média de %ATI/g foi observada no fígado, estômago e fêmur dos animais submetidos à cirurgia de BGYR comparada ao grupo controle (p<0,05). Nos demais órgãos não houve diferença estatisticamente significativa entre os grupos. Em conclusão, a cirurgia BGYR em ratos modificou a biodistribuição do Na99mTc em alguns órgãos, podendo ter implicações clínicas na interpretação de exames cintilográficos. Este estudo xi teve um caráter multidisciplinar com a participação de pesquisadores das áreas de Cirurgia Experimental, Farmácia, Radiobiologia, Medicina Nuclear e Estatística

PURPOSE: Stroke is a high-incidence cerebrovascular disease with elevated morbidity that results in impairments such as functional disabilities. This study aimed to investigate the functional evolution of individuals in the first six months post-stroke. METHOD: Longitudinal study with 42 stroke patients. The functional independence measure (FIM) and The National Institutes of Health Stroke Scale (NIHSS) were used by multidisciplinary staff 3 times in each participant; the first application was at admission to rehabilitation and the others three and six months later. RESULTS: Sample predominantly female (57%), married (52%), mean age 65.26 ±10.72 years, elementary schooling level (43%), ischemic stroke (91%), and right cerebral hemisphere (74%). Motor FIM scores and NIHSS scale showed improvement in the 3 evaluations, with significant p-value (<0.001). There was a strong relation between motor FIM evolution and NIHSS evolution (r = - 0.69 p-value< 0.001). CONCLUSIONS: It was observed that functional evolution at 6 months post-stroke was significant and the smaller the evolution of clinical impairment in these patients, the larger the evolution of their functional independence. The study is important because it allows a more appropriate therapeutic planning according with functional evolution in stroke rehabilitation

(Objective) Assess the functional capacity and determine the difference between the means of functional capacity (basic and instrumental activities of daily living) and the age groups of elderly residents in an outlying area in the hinterland of Bahia/Northeast of Brazil. (Methods) Analytical study with cross-sectional design and a sample of 150 elderly individuals enrolled in four Health Units in the municipality of Jequié, Bahia, Brazil. The instrument consisted of sociodemographic and health data, the Barthel Index and the Lawton scale. (Results) In all, 78.00% of the elderly were classified as dependent in the basic activities and 65.33% in the instrumental activities of daily living. Using the Kruskal- Wallis test, we found a statistically significant difference between the means of instrumental activities and the age groups (p= 0.011). (Conclusion) An elevated number of elderly were classified as dependent in terms of functional capacity and increased age is related to greater impairment in the execution of instrumental activities of daily living

It is a Cross-sectional and multi-disciplinary study whose population selection was made by department of human resources (composed by a Manager, an Oncologist and a Psychologist) from the hospital where this research was realized. They also collaborated with important information about the work of that professionals in the hospital. We also counted on a Statistic who made study design calculating the sample and analyzing data. This research issued Evaluating health professionals anxiety levels who care for cancer terminally ill and their feelings about that work as well as identifying the factors which have influence on it. 100 health professionals from the Hospital which is a reference on cancer caring in Brazil situated in the city of Natal, state of Rio Grande do Norte, participated of this research. There was a sample loss of 21%. Data were collected through a questionnaire and State-Trait Anxiety Inventory (STAI). Results showed that 15% of the professionals have low State Anxiety levels, 70% Medium State Anxiety levels and 15% high State anxiety levels. The Number of Patients and Working in another Institution have interfered in the anxiety levels. Doctors and Nursing Assistants and Technicians have got the highest high State Anxiety percentage (25%). 73% of them declare to feel some sort of different behavior and/or feelings in caring for terminally ill. The most remarkable professionals feelings were Suffering and Sadness, and Terminally ill Children was the most difficult age group to care for. We conclude that work overload and having more than one job can interfere in professional stress levels and anxiety. Dealing with terminally ill, specially children one, can cause on the professionals psychological suffering. It s recommended the development of supporting and training strategies to reduce and/or to prevent Stress and Anxiety high levels

Este estudo teve por objetivo avaliar os fatores associados à disfunção sexual em mulheres de meia idade. Realizou-se um estudo descritivo transversal, que compreendeu 370 mulheres, entre 40 a 65 anos, atendidas nas Unidades Básicas de Saúde de cada distrito sanitário (Norte, Sul, Leste e Oeste) da cidade de Natal, no estado do Rio Grande do Norte, Brasil. Para avaliar a função sexual utilizou-se o Female Sexual Function Index (FSFI). A sintomatologia climatérica foi avaliada por meio do Menopause Rating Scale (MRS). O Índice de Blatt-Kupperman (IMBK) foi utilizado para avaliação quantitativa global da ocorrência de sintomas/queixas. A atividade física foi avaliada pelo questionário International Physical Activity Questionnaire - IPAQ (versão curta). A avaliação da qualidade de vida geral se deu pelo WHOQOL-Bref. A análise estatística foi realizada utilizando o programa estatístico MINITAB version16. Além de análises descritivas das variáveis categorizadas, utilizou-se o teste qui-quadrado de Person com o intuito de verificar possíveis associações entre as variáveis sociodemográficas, comportamentais, clínicas, níveis de atividade física, sintomatologia climatérica, qualidade de vida e a função sexual das mulheres estudadas. Desenvolveu-se a regressão logística para verificar a influência dessas variáveis sobre a disfunção sexual. Considerou-se o nível de significância de 5% para todos os testes. Os resultados mostraram que a média de idade das mulheres estudadas foi de 49,8 (±8,1) anos. Do total dessas mulheres, 67% apresentaram disfunção sexual. Observou-se que 54,5% delas se encontravam na pré-menopausa. Avaliando a influência das variáveis sobre a função sexual; faixa etária (56-65) (p<0,001), estado civil (divorciada/separada) (p < 0,001), escolaridade (baixa) (p=0,017), menopausa (p < 0,001), histerectomia (p = 0,016), nível de atividade física (sedentária) (p=0,002), sintomas do climatério (forte) (p<0,001) e qualidade de vida (baixa) (p<0,001), estiveram associados à disfunção sexual em mulheres de meia idade. Concluiu-se neste estudo que fatores sociodemográficos, clínicos, comportamentais, níveis de atividade física, sintomatologia climatérica e qualidade de vida influenciam significativamente a função sexual na mulher de meia idade

A venous ulcer is the most serious clinical manifestation of chronic venous failure, and the most frequent in lower limbs, accounting for 70% of all ulcers. Patients may suffer from this infirmity for several years without healing of the lesion if treatment is inadequate. The aim of this investigation was to verify the effectiveness of decongestive physical therapy in the healing of venous ulcers. This is a quasi-experimental, interventionist study, with paired, non-probabilistic sampling, composed of 50 patients divided into two groups: control and intervention, each composed of 25 patients. Both groups were identically treated for six months with daily dressings and the latter also underwent complex physical therapy consisting of a combination of the following techniques: manual lymphatic drainage, compression bandaging, lower limb elevation, myolymphokinetic exercises and skin care. The study was approved (Protocol no. 59/2007) by the Ethics Committee of the State University of Southeast Bahia. The Mann-Whitney and Chi-square tests were applied for data analysis. After statistical analysis the patients who underwent therapy showed a statistically significant difference with respect to wound contraction starting in the second month of treatment. Compared to the control, the intervention group showed a greater reduction in both pain and edema starting in the third and fourth month of therapy, respectively. To reinforce these findings, the mean percentage of tissue present at the base of the ulcer (granulation/fibrin ratio) was calculated. The intervention group showed greater granulation at the base of the ulcer compared to the control, significant from the second month of treatment on. It was observed in this study that lymphotherapy, when compared between the intervention and control groups, accelerated the healing process, and reduced pain and edema in the affected limbs. It is expected, therefore, that these results widen scientific knowledge and we suggest that this therapy be used 78 not only to reduce lymphedema, but also as a treatment option for venous ulcers, given its easy application and low cost. The data, therefore, demonstrated the importance of basic care on the part of a multiprofessional and transdisciplinary health team involved in the healing process of these infirmities, thereby contributing to better quality of life in these individuals

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
