A associao entre fatores de risco cardiovascular (FRCV) na psmenopausa e o antecedente de irregularidade menstrual no menacme foi avaliado em estudo caso-controle envolvendo 414 mulheres na psmenopausa com idade de 60,4 5,5 anos e IMC de 25,3 4,7 kg/m2. As variveis consideradas foram: caracterizao do ciclo menstrual entre 20 e 35 anos (independente) e relato atual sobre ocorrncia de hipertenso arterial, dislipidemia, diabetes mellitus e doena arterial coronariana (dependentes). Utilizou-se o teste qui-quadrado e modelos de regresso logstica, ajustados para outras variveis implicadas no risco para doenças CV, com nvel de significncia 5%. Observou-se que mulheres que relataram irregularidade menstrual prvia estiveram associadas com risco aumentado para ocorrncia de algum FRCV [odds ratio ajustado (OR)= 2,14; IC-95%= 1,024,48], quando comparadas quelas com ciclos regulares. Anlise estratificada demonstrou as seguintes associaes significativas com o antecedente de irregularidade menstrual: hipertenso arterial (OR= 2,4; 95% IC= 1,395,41), hipercolesterolemia (OR= 2,32; 95% IC= 1,174,59), hipertrigliceridemia (OR= 2,09; 95% IC= 1,104,33) e angioplastia coronariana (OR= 6,82; 95% IC= 1,4432,18). Os dados sugerem que o antecedente de irregularidade menstrual, indicativo da ocorrncia da sndrome dos ovrios policsticos na idade reprodutiva, pode estar relacionado com aumento do risco para doenças CV na ps-menopausa __________________________________________________ABSTRACT Menstrual Cycle Irregularity as a Marker of Cardiovascular Risk Factors at Postmenopausal Years.To evaluate the association between cardiovascular risk factors (CVRF)during postmenopausal years and previous menstrual irregularity during reproductive years, we performed a case-control study in 414 postmenopausal women (mean age 60.4 5.5 years; BMI 25.3 4.7 kg/m2). The variables assessed were: menstrual cycle characteristics at age 2035y (independent) and records of arterial hypertension, dyslipidemia, diabetes mellitus, and coronary heart disease (dependent). Statistical analysis used the chi-square test and logistic regression, adjusting for potential confounders for cardiovascular risk, with significance set at 5%. Women reporting previous menstrual irregularity were associated with increased risk for some CVRF [adjusted odds ratio (OR) 2.14; CI-95%= 1.024.48], when compared with those reporting regular menstrual cycles. Stratified analysis demonstrated significant associations of previous menstrual irregularity with: arterial hypertension [OR= 2.74; CI-95%= 1.395.41), hypercholesterolemia (OR= 2.32; CI-95%= 1.174.59), hypertriglyceridemia (OR= 2.09; CI-95%=1.104.33), and coronary angioplasty (OR= 6.82; CI-95%= 1.4432.18). These data suggest that a prior history of menstrual irregularity, as indicative of polycystic ovary syndrome, may be related to increased risk for CVD during postmenopausal years

Objective: To verify the accuracy of the waist circumference (WC), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR) and the conicity index (CI) in the detection of cardiovascular risk factors (CVRF) in women with PCOS. Methods: The present transversal study allocated 102 women (26.5 5 years) with a diagnosis of PCOS, according to the Rotterdam criteria. Total cholesterol (TC), triglycerides (TG), LDL-cholesterol (LDL-C), HDL-cholesterol (HDL-C), fasting glucose, glucose after the oral glucose tolerance test (OGTT) and blood pressure (BP) were evaluated in all patients, in addition to the anthropometric variables. Results: The WHtR was the marker that presented significant positive correlations with the highest number of CVRF (BP, TG and post-OGTT glucose), whereas there was a negative correlation with HDL-C. All the evaluated anthropometric markers were positively correlated with BP, whereas WC and WHR also presented a positive correlation with TG. Regarding the accuracy for the detection of CVRF, the anthropometric markers presented a sensibility > 60%, especially the WHtR, which had a sensibility > 70%. Conclusion: The WHtR showed to be the most accurate anthropometric indicator for the prediction of CVRF. In this sense, we propose the inclusion of this easily-measured parameter in the clinical assessment for the screening of women with PCOS and CVRF

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 Janurio 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

Despite the observation of an increase in life expectancy in individuals with Spinal cord injury (SCI), it is lower than that of the general population. Studies have shown that affected individuals have a sedentary lifestyle that reflects negatively on health and quality of life. Studies have demonstrated that HDL cholesterol (HDL-C) levels, a high-density lipoprotein and important predictor of cardiovascular disease, are lower in this population exposing these people to a greater incidence of heart disease from atherosclerotic process In the general population, exercise increases HDL-C serum levels, but this phenomenon is not very clear in people with spinal cord injury (SCI). The present study examined the effect of both swimming and wheelchair basketball in the lipid profile of eleven men and seven women with SCI. The subjects included in regular exercise programs showed increases in HDL-C levels and decreases in CT/HDL-C and LDL-C/HDL-C ratios. We found better results mainly in men with lower levels of SCI and in those that sustained exercise intensities above 60% of the heart rate reserve. The duration of training sessions can be an essential factor in these results. The results suggest that both the exercise prescription and the personal characteristics of people with SCI influence changes in the lipid profile mediated through exercise. The elaboration of this work is an attempt to clarify uncertainties about health and the longevity of people with SCI generated in discussion of all members of the interdisciplinary rehabilitation team, especially the physiotherapists, nutritionists, nurses and physicians that contributed considerably in all phases of the research

The metabolic syndrome (MetS) involves a group of risk factors and is associated with a significantly higher risk of developing cardiovascular diseases (CVD) and type 2 diabetes. Recent studies have shown the importance of preventing CVD through early diagnosis and treatment of patients with MetS. The objective of our study was to determine the prevalence of MetS by different diagnostic criteria in postmenopausal women and analyze the influence of socioeconomic factors on cardiovascular risk in this sample of the population. A cross-sectional study involving 127 postmenopausal women (45 to 64 years) from Natal and Mossor, Brazil. The study was approved by the Research Ethics Committee of the Federal University of Rio Grande do Norte. The experimental protocol consisted of applying structured interview, clinical examination and implementation of dosages blood. The diagnosis of MetS was based on NCEP-ATP III (National Cholesterol Education Program-Adult Treatment Panel III) and IDF (International Diabetes Federation) criteria. The research was accomplished with the participation of an interdisciplinary team in their several phases. The result of the sample studied had mean age of 53.9 4.6 years and per capita income of 54.5 dollars. The prevalence of MetS, according to NCEP-ATP III and IDF criteria, was 52.8% and 61.4$, respectively. The agreement rate between NCEP-ATP III and IDF criteria was 81.9%, with a kappa value of 0.63 (CI 95%, 0.49-0.76), indicating good agreement between the two definitions. The most prevalent cardiovascular risk factor was HDL < 50 mg/dl, observed in 96.1% of the women analyzed, followed by increased waist circumference (&#8805; 80 cm) in 78.0%, elevated blood pressure in 51.2%, triglycerides &#8805; 150 mg/dl in 40.9% and glycemia &#8805; 100 mg/dl in 37.0% of the women. The occurrence of MetS was significantly associated with schooling and body mass index (BMI). High blood pressure was significantly associated with low family income, low schooling and weight gain. There was no significant association between the intensity of climacteric symptomatology and the occurrence of MetS. The conclusions of the research were that MetS and its individual components show a high prevalence in postmenopausal Brazilian women, and significant associations with weight gain and low socioeconomic indicators. The data point to the need for an interdisciplinary approach at the basic health care level, directed toward the early identification of risk factors and the promotion of cardiovascular health of climacteric women.

The dyslipidemia and excess weight in adolescents, when combined, suggest a progression of risk factors for cardiovascular disease (CVD). Besides these, the dietary habits and lifestyle have also been considered unsuitable impacting the development of chronic diseases. The study objectives were: (1) estimate the prevalence of lipid profile and correlate with body mass index (BMI), waist circumference (WC) and waist / height ratio (WHR) in adolescents, considering the maturation sexual, (2) know the sources of variance in the diet and the number of days needed to estimate the usual diet of adolescents and (3) describe the dietary patterns and lifestyle of adolescents, family history of CVD and age correlates them with the patterns of risk for CVD, adjusted for sexual maturation. A cross-sectional study was performed with 432 adolescents, aged 10-19 years from public schools of the Natal city, Brazil. The dyslipidemias were evaluated considering the lipid profile, the index of I Castelli (TC / HDL) and II (LDL / HDL) and non-HDL cholesterol. Anthropometric indicators were BMI, WC and WHR. The intake of energy, nutrients including fiber, fatty acids and cholesterol was estimated from two 24-hour recalls (24HR). The variables of lipid profile, anthropometric and clinical data were used in the models of Pearson correlation and linear regression, considering the sexual maturation. The variance ratio of the diet was calculated from the component-person variance, determined by analysis of variance (ANOVA). The definition of the number of days to estimate the usual intake of each nutrient was obtained by taking the hypothetical correlation (r) &#8805; 0.9, between nutrient intake and the true observed. We used the principal component analysis as a method of extracting factors that 129 accounted for the dependent variables and known cardiovascular risk obtained from the lipid profile, the index for Castelli I and II, non-HDL cholesterol, BMI, and WC the WHR. Dietary patterns and lifestyle were obtained from the independent variables, based on nutrients consumed and physical activity weekly. In the study of principal component analysis (PCA) was investigated associations between the patterns of cardiovascular risk factors in dietary patterns and lifestyle, age and positive family history of CVD, through bivariate and multiple logistic regression adjusted for sexual maturation. The low HDL-C dyslipidemia was most prevalent (50.5%) for adolescents. Significant correlations were observed between hypercholesterolemia and positive family history of CVD (r = 0.19, p <0.01) and hypertriglyceridemia with BMI (r = 0.30, p <0.01), with the CC (r = 0.32, p <0.01) and WHR (r = 0.33, p <0.01). The linear model constructed with sexual maturation, age and BMI explained about 1 to 10.4% of the variation in the lipid profile. The sources of variance between individuals were greater for all nutrients in both sexes. The reasons for variances were &#61500; 1 for all nutrients were higher in females. The results suggest that to assess the diet of adolescents with greater precision, 2 days would be enough to R24h consumption of energy, carbohydrates, fiber, saturated and monounsaturated fatty acids. In contrast, 3 days would be recommended for protein, lipid, polyunsaturated fatty acids and cholesterol. Two cardiovascular risk factors as have been extracted in the ACP, referring to the dependent variables: the standard lipid profile (HDL-C and non-HDL cholesterol) and "standard anthropometric index (BMI, WC, WHR) with a power explaining 75% of the variance of the original data. The factors are representative of two independent variables led to dietary patterns, "pattern 130 western diet" and "pattern protein diet", and one on the lifestyle, "pattern energy balance". Together, these patterns provide an explanation power of 67%. Made adjustment for sexual maturation in males remained significant variables: the associations between puberty and be pattern anthropometric indicator (OR = 3.32, CI 1.34 to 8.17%), and between family history of CVD and the pattern lipid profile (OR = 2.62, CI 1.20 to 5.72%). In females adolescents, associations were identified between age after the first stage of puberty with anthropometric pattern (OR = 3.59, CI 1.58 to 8.17%) and lipid profile (OR = 0.33, CI 0.15 to 0.75%). Conclusions: The low HDL-C was the most prevalent dyslipidemia independent of sex and nutritional status of adolescents. Hypercholesterolemia was influenced by family history of CVD and sexual maturation, in turn, hypertriglyceridemia was closely associated with anthropometric indicators. The variance between the diets was greater for all nutrients. This fact reflected in a variance ratio less than 1 and consequently in a lower number of days requerid to estimate the usual diet of adolescents considering gender. The two dietary patterns were extracted and the pattern considered unhealthy lifestyle as healthy. The associations were found between the patterns of CVD risk with age and family history of CVD in the studied adolescents

Introduo: Os hormnios estrognicos possuem importante papel na defesa contra as espcies reativas do oxignio, fato que se evidencia na maior incidncia de doenças cardiovasculares e neurodegenerativas aps a menopausa. O exerccio fsico melhora as defesas antioxidantes, contudo em altas cargas e em baixas concentraes de estrgeno possui efeito aditivo ao dano oxidativo. O cido &#945;-lipico possui uma ampla gama de ao antioxidante e poderia contribuir para diminuio do dano nestas condies. Objetivo: O objetivo deste estudo caracterizar a ao do cido &#945;-lipico sobre a adaptao antioxidante e funes reprodutivas de ratas submetidas a natao moderada. Material e mtodos: Os animais foram submetidos a natao diria (1 hora) e sacrificados aps 30, 60 e 90 dias. Os animais foram divididos em controles sedentrios e exercitados; suplementados (cido &#945;-lipico 100mg/Kg/dia) sedentrios e exercitados e animais ovariectomizados e suplementados com cido lipico. Avaliou-se diariamente o ciclo estral e os seguintes marcadores de estresse oxidativos foram mensurados em fgado e sangue: atividade enzimtica da SOD, GPx e CAT, alm do SRAT e GSH. Resultados: O protocolo de exerccio aumentou a durao do ciclo estral no grupo controle exercitado, sobretudo na fase diestral. Neste mesmo grupo, houve diminuio da lipoperoxidao com melhora da atividade antioxidante da SOD e GPx. O grupo exercitado e suplementado no apresentou alterao na durao do ciclo estral e manteve os benefcios sobre o sistema antioxidante antes observado nos animais exercitados. A suplementao antioxidante juntamente com a natao em perodos superiores a 30 dias, diminuiu o processo de adaptao antioxidante quando comparado aos animais somente exercitados. Nos animais ovariectomizados, o exerccio e a suplementao com cido lipico no promoveu adaptao antioxidante ao contrrio dos demais grupos. Concluso: O aumento na durao do ciclo estral e a melhora nos marcadores de estresse oxidativo seriam uma resposta adaptativa frente ao exerccio moderado. O cido lipico impediu a alterao no ciclo induzida pelo exerccio, mas preservou a melhoria no sistema antioxidante. A depleo estrognica provocada pela ovariectomia eleva o potencial de dano oxidativo gerado pelo exerccio. A ao antioxidante do LA na presena de estrgeno diminuiu excessivamente o dano oxidativo, comprometendo a adaptao antioxidante a natao. Nos animais ovariectomizados, contudo, o AL promoveu adaptao antioxidante ao exerccio

Heart transplantation (HT) represents one of the greatest advances in medicine over the last decades. It is indicated for patients with severe heart disease unresponsive to clinical treatment and conventional surgery, poor short-term prognosis and a 1- year mortality rate over 40%. HT has improved survival worldwide (80% in the first year, 70% in five years and 60% in ten years). However, the procedure has been associated with weight change and increased risk of secondary conditions such as diabetes, hypertension, dyslipidemia and obesity due to immunosuppressive therapy following transplantation. The objective of this study was to determine the impact of weight change on the metabolic stability of HT patients. The study was retrospective with data collected from the records of 82 adult patients (83% male; average age 45.0612.04 years) submitted to HT between October 1997 and December 2005 at a transplantation service in Cear (Brazil). The selected outcome variables (biopathological profile, weight and body mass index&#8213;BMI) were related to biochemical and metabolic change. The results were expressed in terms of frequency, measures of central tendency, Student s t test and Pearson s correlation coefficients. The analysis showed that following HT the average global BMI increased from 23.773.68kg/m2 to 25.483.92kg/m2 in the first year and to 28.384.97kg/m2 in the fifth. Overweight/obese patients (BMI &#8805; 25 kg/m2) had higher average levels of glucose, total cholesterol, low-density lipoprotein and triglycerides than patients with eutrophy/malnutrition (BMI < 25 kg/m2). In conclusion, overweight/obese patients were likely to present higher average levels of glucose, triglycerides, total cholesterol and fractions than patients with eutrophy/malnutrition, indicating a direct and significant relation between nutritional status and weight change in the metabolic profile of HT patients

The aim of the present study was to analyze cardiovascular risk of women with a history of preeclampsia, as well as its follow-upin the National Health System.This is a cross-sectional quantitative research conducted at the Janurio Cicco Maternity School. The study population was composed of 573 women selected from a databank belonging to the Women s Health Research Group of the Gynecology Department at Universidade Federal do Rio Grande do Norte, with a history of preeclampsia, and normotensives who gave birth at this institution five years before. The final sample consisted of 147 women, 64 in the group with a history of PE and 83 normotensives. Data were collected on a questionnaire containing the following: sociodemographic aspects, anthropometric measures, life habits, personal and family history of pregnancy-induced hypertension, family history of cardiovascular diseases and frequency of measuring current blood pressure levels. In relation to the association between cardiovascular risk and altered blood pressure (&#8805;130x85 mmHg), the likelihood of exhibiting the latter condition was significantly higher in women with a history of preeclampsia (CI 95% 4.12-38.92), the overweight and obese (CI 95% 1.70-20.75), and in those with a family historyof CVD and personal history of PIH (CI 95% 0.78-47.07 and CI 95% 3.20-25.39) respectively. Likewise, the probability of having altered blood pressure was higher in women with fasting glycemia &#8805;100mg/dL (CI 95% 2.09-24.73), as well as in those with triglycerides &#8805;150mg/dl (CI 95% 1.72-9.66). After fitting the logistic model, diagnosis previous preeclampsia and altered triglycerides remained as explanatory variables.The women with a history of preeclampsia five years before exhibited altered blood pressure levels, clinical and laboratory manifestations suggestive of elevated risk for cardiovascular disease, as well as family and personal history of hypertension. There is no differential treatment or adequate outpatient follow-up for this population in basic health care units

As condies de vida so usualmente entendidas como importantes fatores intervenientes das causas bsicas de mortalidade e da qualidade de vida da populao. Ao considerar esta questo em uma populao idosa e sua influncia nas causas mais relevantes que as levam morte, teve-se como objetivo principal, estudar a associao da mortalidade dos idosos por doenças cardiovasculares para ambos os sexos, com indicadores que expressam as condies de vida da populao do Nordeste, nos anos 2000 e 2010. Para atingir tal propsito foi traado um desenho de estudo ecolgico com cortes transversais nos anos 2000 e 2010 tendo como unidades de anlises as microrregies e a mesorregies do Nordeste. Utilizou-se a Modelagem de Equaes Estruturais (MEE) para explicar essas associaes, tomando como base as estatsticas de bitos por doenças cardiovasculares (construto endgeno) e variveis socioeconmicas e demogrficas (construto exgeno) das microrregies do Nordeste, para o ano 2000. Utilizou-se o Mtodo dos Componentes Principais como recurso metodolgico na construo de um ndice sinttico que permitiu classificar as condies de vida nas mesorregies do Nordeste, tomadas como unidades de anlises, nos anos 2000 e 2010, de acordo com as condies de vida e as principais causas de mortalidade por doenças cardiovasculares. A aplicao da MEE sugeriu uma forte associao do construto exgeno condies de vida, composto pelos indicadores: anos de estudo dos homens idosos, percentual de idosos em domiclios com banheiro/gua encanada e probabilidade de sobrevivncia aos 60 anos, com a varivel desfecho taxa de mortalidade por doenças cardiovasculares dos homens e mulheres idosos. O ndice sinttico construdo permitiu identificar os diferentes ritmos de envelhecimento populacional entre as regies e distintos processos de evoluo dos nveis de mortalidade pelas doenças cardiovasculares, muitas delas compatveis com as condies de vida no Nordeste. Os resultados sugerem que o construto condies de vida est fortemente associado por esta causa de morte entre os idosos para ambos os sexos no Nordeste do Brasil. Neste sentido, sugere-se que estes resultados sejam considerados como relevantes para formulao de polticas de sade regionais voltadas para este contingente populacional do Nordeste do Brasil

Nas ltimas dcadas, houve grande aumento da prevalncia de obesidade, inclusive na faixa etria peditrica. Com isso, aumentou o nmero de crianas e adolescentes afetados por sndrome metablica (SM), diabetes tipo 2 (DM2) e doenças cardiovasculares (DCV), doenças anteriormente consideradas quase exclusivas de adultos. Os objetivos do estudo foram identificar e correlacionar marcadores antropomtricos (IMC- ndice de massa corprea, CA- circunferncia abdominal, RCQ- razo cintura/quadril, RCArazo cintura altura e PSE- prega subescapular), PAS e PAD- presso arterial sistlica e diastlica, respectivamente, e laboratoriais (CT- colesterol total, HDL, LDL, TGL- triglicrides, I/G- razo insulina glicose, HOMA- homeostatic model assessment for insulin resistance) de risco para o desenvolvimento de SM e observar a sua prevalncia em crianas e adolescentes com excesso de peso. Foi conduzido estudo transversal, em amostra aleatria, de convenincia, onde foram avaliadas 60 crianas e adolescentes com excesso de peso, atendidas no ambulatrio de endocrinologia peditrica do Hospital de Pediatria da Universidade Federal do Rio Grande do Norte (UFRN) com idade mnima e mxima de 7 e 15 anos, de maio de 2009 a abril de 2010. Foram admitidos os indivduos que apresentavam sobrepeso (IMC P > 85 e < 95) ou obesidade (IMC P > 95) (CDC, 2000) e histria familiar positiva para DM2 em parentes de primeiro ou segundo grau ou algum dos sinais de resistncia insulnica (acantose, hipertenso arterial, dislipidemia, sndrome de ovrios policsticos). 2 O componente individual para SM mais prevalente foi o percentil da CA &#8805; 90 (58,3%), seguido de HDL &#8804; 40 mg/dl (36,6%). Na regresso linear simples, observaram-se as variaes para mais nos parmetros laboratoriais e de PA para cada unidade de aumento de IMC, CA, RCA, RCQ e PSE, sendo significantes as seguintes correlaes: CA com TGL, HOMA IR, I/G, PAS e PAD; RCQ com TGL, HOMA, I/G, LDL e glicemia; RCA com TGL; PSE com TGL, HOMA-IR, I/G e PAS; e IMC com HOMA IR, I/G, PAS e PAD. De acordo com os critrios da IDF (Federao Internacional de Diabetes International Diabetes Federation) 2007, o diagnstico de SM foi encontrado em seis indivduos (10%). Do total, oito (13,3%), estavam em situao de sobrepeso e 52 (86,6%), obesos. As evidncias de correlao CA e RCQ, medidas de obesidade centrpeta, com vrios marcadores como TGL e HOMA, j sabidamente relacionados SM, chamam ateno para a necessidade de utilizao dessas medidas de forma mais rotineira na prtica peditrica, por serem de fcil obteno, baixo custo e mtodo no invasivo. Os valores de CA, RCQ, RCA e PSE, quando elevados devem justificar maior detalhamento na avaliao laboratorial de possvel resistncia insulnica. importante a identificao de crianas e adolescentes que preencham os requisitos para o diagnstico da SM, pois so indivduos de maior risco metablico e devem ser adequadamente acompanhados.

Resumo:

The lipid profile is a group of lab tests that include triglycerides, total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C). However, serum non-HDL-C, Apo A-I and Apo B levels, as well as the lipids ratios (TC/HDL-C, LDL-C/HDL-C and Apo B/Apo A-I), have been described as better predictors of cardiovascular diseases. Reference intervals are tools often used to help the evaluation of the people s health state. These days, Brazilian studies still use the reference intervals of lipids and lipoproteins from other countries, ignoring differences between the populations. Therefore, this study aimed to establish reference intervals for lipids, lipoproteins and apolipoproteins in adults of Rio Grande do Norte/Brazil. Healthy individuals (96 men and 283 women) between 18 and 59years old formed the reference sample group. The samples were collected after fasting 12 to 14 hours. Information on lifestyle and dietary habits of the participants were obtained through questionnaire. The serum glucose level and renal and liver activity were evaluated by laboratory testing. The results of lipid profile were analyzed according to sex, age and mesoregion of Rio Grande do Norte, with significance level of 5% (p < 0,05). The lower and upper reference limits were identified by the 2.5 percentile and 97.5 percentile, respectively, and assurance intervals of 90% was calculated for each of these limits. Among the determinants of lipid profile analyzed, only a few significant differences were observed according to sex, but in terms of age, the groups of smaller and older ages were most likely different. When evaluated by region, the means of West region shown the most significant variations. Not many studies were useful to compare the reference intervals determined in this study. Thus, it becomes necessary to carry out similar studies in other regions of Brazil and of the world given the clinical importance of reference intervals
