OBJECTIVE: To determine the prevalence of dyslipidemias in adults in the city of Campos dos Goytacazes, in the Brazilian state of Rio de Janeiro, and to identify its relation to risk factors. METHODS: Cross-sectional, population-based, observational study with sampling through conglomerates and stratified according to socioeconomic levels, sex, and age, with 1,039 individuals. Risk factors, familial history, blood pressure, anthropometric measurements, glucose, triglycerides and cholesterol were determined. RESULTS: The following prevalences were observed: of dyslipidemias 24.2%; of hypercholesterolemia, 4.2%; of elevated LDL-C, 3.5%; of low HDL-C, 18.3%; and of hypertriglyceridemia, 17.1%. The following mean levels were observed: cholesterol, 187.6± 33.7 mg/dL; LDL-C, 108.7±26.8 mg/dL; HDL-C, 48.5±7.7 mg/dL; and triglycerides, 150.1±109.8 mg/dL. The following variables showed a positive correlation with dyslipidemia: increased age (P<0.001), male sex (P<0.001), low familial income (P<0.001), familial history (P<0.01), overweight/obesity (P<0.001), waist measure (P<0.001), high blood pressure (P<0.001), and diabetes mellitus (P<0.001). The following variables had no influence on dyslipidemias: ethnicity, educational level, smoking habits, and sedentary lifestyle. CONCLUSION: The frequency of lipid changes in the population studied was high, suggesting that measures for the early diagnosis should be taken, in association with implementation of programs for primary and secondary prevention of atherosclerosis.

OBJECTIVE: To determine the prevalence of dyslipidemias in adults in the city of Campos dos Goytacazes, in the Brazilian state of Rio de Janeiro, and to identify its relation to risk factors.

METHODS: Cross-sectional, population-based, observational study with sampling through conglomerates and stratified according to socioeconomic levels, sex, and age, with 1,039 individuals. Risk factors, familial history, blood pressure, anthropometric measurements, glucose, triglycerides and cholesterol were determined.

RESULTS: The following prevalences were observed: of dyslipidemias 24.2%; of hypercholesterolemia, 4.2%; of elevated LDL-C, 3.5%; of low HDL-C, 18.3%; and of hypertriglyceridemia, 17.1%. The following mean levels were observed: cholesterol, 187.6± 33.7 mg/dL; LDL-C, 108.7±26.8 mg/dL; HDL-C, 48.5±7.7 mg/dL; and triglycerides, 150.1±109.8 mg/dL. The following variables showed a positive correlation with dyslipidemia: increased age (P<0.001), male sex (P<0.001), low familial income (P<0.001), familial history (P<0.01), overweight/obesity (P<0.001), waist measure (P<0.001), high blood pressure (P<0.001), and diabetes mellitus (P<0.001). The following variables had no influence on dyslipidemias: ethnicity, educational level, smoking habits, and sedentary lifestyle.

CONCLUSION: The frequency of lipid changes in the population studied was high, suggesting that measures for the early diagnosis should be taken, in association with implementation of programs for primary and secondary prevention of atherosclerosis.

Key words: dyslipidemias, prevalence, hypercholesterolemia, hypertriglyceridemia, hyperlipidemia.

Currently, atherosclerosis is undoubtedly the major cause of mortality in developed countries. Due to the evolutional process of industrialization and urban concentration, with consequent changes in lifestyle, Brazil has also joined this world scenario. Although multifactorial, dyslipidemias play a determinant and direct role in the genesis of atherosclerosis and in its consequent cardiovascular and cerebrovascular risks 1-4.

In the last few years, several studies have confirmed the premise that a reduction in cholesterol levels causes a reduction in the risk of coronary events, both in primary and secondary preventions 5-9.

If effective preventive measures are not taken, epidemicity has been foretold with calamitous consequences to public health 1,10. Therefore, tools for the epidemiological evaluation of lipid profiles are essential for the development and promotion of health polices to reduce cardiovascular mortality 11,12.

The prevalence of dyslipidemias varies according to the ethnic, socioeconomic, and cultural characteristics of distinct population groups 10,13,14. In Brazil, reliable studies determining the actual prevalence of dyslipidemias in a group of individuals statistically representative of a free and geographically delimited population are scarce 13,15,16. Most studies comprise restricted groups limited to a certain age range 17-20, such as ambulatory patients 11,21, individuals with already established coronary artery disease 22, and students 23 or employees of a single institution 11,14,24-29, or use secondary databanks from laboratories for clinical analyses 13,15. In addition, almost all those studies have only analyzed total cholesterol levels, not allowing complete evaluation of the lipid profile of the population.

The lipid profile defined by the III Brazilian Guidelines on Dyslipidemias (III Diretrizes Brasileiras sobre Dislipidemias) 1 comprises an assessment of total cholesterol (TC), triglycerides (TG), and HDL-cholesterol (HDL-C), and the calculation of LDL-cholesterol (LDL-C) with the Friedewald formula. Based on the results of those parameters, the laboratory classification of dyslipidemias may be established as follows: isolated hypercholesterolemia, isolated hypertriglyceridemia, mixed hyperlipidemia, and low HDL-cholesterol.

This study is part of a project developed in the city of Campos dos Goytacazes, in the Brazilian state of Rio de Janeiro, aiming at determining the prevalence of high blood pressure, diabetes mellitus, dyslipidemias, and obesity in adults. The original project was stratified, allowing a careful assessment of each of those diseases. In this study, the prevalence of dyslipidemias in a representative sample of the urban population aged more than 18 years in the city of Campos dos Goytacazes was determined, as was the relation of dyslipidemias with biological, socioeconomic and cultural factors, and other associated morbidities.


A cross-sectional, population-based, observational study was carried out with sampling through conglomerates and stratified according to socioeconomic levels, sex, and age.

The target population comprised the residents in the city of Campos dos Goytacazes, in the state of Rio de Janeiro [population 363,489 according to the IBGE (Brazilian Institute of Geography and Statistics), 2000], with age > 18 years, which corresponded approximately to 221,000 people.

Based on sampling calculations, the number of 1,039 individuals was determined as the required participation to carry out a study with accuracy < 3% and a confidence interval of 95%.

The sample was stratified based on the sectors of the IBGE census of 2000 for the population of the city of Campos dos Goytacazes. The sectors of the census were divided according to the socioeconomic levels of the population into heterogeneous and homogeneous. The heterogeneous sectors were ruled out, and the homogeneous sectors were divided into 5 groups according to the familial income in minimum wages (MW) as follows: group A - less than 1 MW; group B - from 2 to 5 MW; group C - from 6 to 10 MW; group D - from 11 to 20 MW; group E - more than 20 MW. The number of sectors to be studied per group to allow proportionality between the sample and the city population was as follows: 6 sectors in group A (82 interviewees per sector), 5 sectors in group B (86 interviewees per sector), 1 sector in group C (77 interviewees), 1 sector in group D (35 interviewees), and 1 sector in group E (25 interviewees), adding to a total of 1,039 interviewees in 14 sectors of the census. The sectors in the groups were chosen according to the criterion of population density in the sector and ease of access, including an analysis about the level of violence in the sectors. In each sector chosen, 4 streets were initially selected, and, on each street, the residences were approached alternately on both sides of the street until completing the required number of interviewees in the sector. When necessary, other streets in the sector were approached to complete the minimum number of interviewees.

In each sector, we tried to maintain the distribution between the sexes proportional to that of the population of the city of Campos dos Goytacazes: 49% for the male sex and 51% for the female sex. All values were adjusted according to the age structure, considering the population of both sexes above the age of 18 years and based on the IBGE data for the year 2000.

Data were collected in 2 stages from January to September 2001. The first stage comprised the completion of a questionnaire containing the following parameters: identification, sex, age, familial history, socioeconomic levels, educational level, anthropometric parameters, and 2 measurements of blood pressure at a 10-minute interval. In the second stage, scheduled 24 to 48 hours after the first, with the patient fasting for 12 hours, blood was drawn and a new blood pressure measurement was taken. A mean of the 2 blood pressure measurements of the first visit was calculated and compared with the measurement of the second visit.

Plasma lipids and glycemia measurements were obtained from the 10 mL of venous blood drawn after 12 hours of fasting between 7 and 9 AM. The blood samples were placed in a Styrofoam box with ice, which was sealed and immediately sent to the laboratory of the university-affiliated Hospital Escola Álvaro Alvim (HEAA). This hospital participates in the quality control program of the Brazilian Society of Clinical Pathology. Total cholesterol (TC) was determined with the cholesterol oxidase/peroxidase enzymatic method in a spectrophotometer. Serum triglycerides were established with the glycerol enzymatic method, and HDL-C was determined with the precipitating reactive method. LDL-C was calculated with the Friedewald formula as follows: LDL-C = (TC - HDL-C) – (TG/5), valid if TG < 400 mg/dL. Serum glycemia was established with the glucose oxidase method.

Data were collected by 8 interviewers (grouped into 4 pairs) selected at the Escola Técnica Estadual Barcelos Martins and trained for the interview, and how to measure weight, height, and blood pressure, and how to draw blood.

Quality control of data collection was performed through permanent follow-up and supervision of the field work by the authors.

Participation in the study was voluntary and the participants could quit at any time. Data confidentiality was guaranteed by the research team. All individuals who refused to undergo blood collection or who were not found in the second visit were excluded from the study.

Normativeness of blood pressure measurement followed the criteria defined by the VI Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure 30. Blood pressure was measured according to the indirect method with calibrated aneroid sphygmomanometers, which had never been used before, with a standard adult cuff and 0.5-mmHg pressure gradations. The individuals with altered blood pressure (> 140x90 mmHg) at both visits and those undergoing treatment for high blood pressure were classified as hypertensive 4,30.

The reference value of fasting glycemia used as the cut off point to classify individuals as diabetic or nondiabetic was 126 mg/dL, according to the Brazilian Consensus on Diabetes (2000) 31. Patients whose fasting glycemia was between 126 and 200 mg/dL had their tests repeated for diagnostic confirmation using the same criterion. Patients who reported being then under treatment for diabetes were considered diabetic.

The classification of the reference values for total cholesterol, triglycerides, LDL-C, and HDL-C followed the criteria of the III Brazilian Guidelines on Dyslipidemia 1 (tab. I). The following lipid levels classified as high and very high were used for defining prevalences: TC > 240 mg/dL or HDL-C < 40 mg/dL or LDL-C > 160 mg/dL or TG > 200 mg/dL. The characterization of dyslipidemias involved the 4 altered parameters in isolation or in association and the individuals with lipid disorders under specific medication.

Obesity and overweight were assessed through the calculation of body mass index (BMI) 32,33. Weight was measured with the individuals lightly dressed and without shoes on a portable scale with a capacity for 120 kg and precision of 0.1 kg. In regard to height, tape measures with a 0.5-cm scale were used. People whose BMI was > 30 kg/m2 were considered obese, and those with BMI between 25 and 30 kg/m2 were considered overweight.

Waist circumference was measured with a nonextendable synthetic measuring tape scored in centimeters. The cut off points of 102 cm for males and 88 cm for females were used as reference values of very increased risk for metabolic complications associated with obesity in Caucasians 34.

The results were sent to the participants, and all hypertensive, diabetic, dyslipidemic, and obese patients were referred for follow-up in the outpatient care clinics at the HEAA.

Individuals who reported not undergoing regular physical exercise at a frequency > twice a week with a minimum duration of 30 minutes were considered sedentary.

The statistical analyses were processed using the Epi Info 6.04b program. The total and relative prevalences of dyslipidemias were calculated according to the stratification of the last consensus 1. The mean and standard deviation and its variation in regard to sex and age were determined using the Student t test. The chi-square test was used for association between the lipid profile variables (dyslipidemias, total cholesterol, triglycerides, HDL-C, and LDL-C) and the risk variables (sex, age, race, census sector, educational level, familial history, smoking, sedentary lifestyle, overweight, obesity, waist measure, high blood pressure, and diabetes mellitus). No cut off point was established for P values, which were presented as calculated.


This study assessed 1,039 individuals, 497 (47.8%) of whom were males and 663 (64.4%) were Caucasians. Age ranged from 18 to 96 (48.8±16.6) years.

The total prevalence of dyslipidemias adjusted for age was 24.2%. When stratifying the results according to the laboratory alterations, the following prevalences were obtained: hypercholesterolemia, 4.2%; high LDL-C, 3.5%; low HDL-C, 18.3%; and hypertriglyceridemia, 17.1%. The distribution of the results at intervals according to the reference values for the diagnosis of dyslipidemias may be seen in table I.

Table II shows the mean values and standard deviation of the lipid levels according to sex and age group, a positive correlation (P<0.001) being observed in both cases. By determining the population mean, the following values were observed: cholesterolemia of 187.6±33.7 mg/dL; LDL-C of 108.7±26.8 mg/dL; HDL-C of 48.5±7.7 mg/dL; and triglyceridemia of 150.1±109.8 mg/dL.

The age group from 50 to 59 years had the greatest TC, LDL-C, and TG means, and the lowest HDL-C means. The TC means in the female sex exceeded those in the male sex from the fifth decade of life onwards. LDL-C levels were greater in females in all age groups, but, on the other hand, TG levels were greater in males.

The prevalence of dyslipidemias increased from 10.7% in the age group from 18 to 29 years to 37.7% in the age group from 50 to 59 years, a reduction to 31% being observed in individuals older than 70 years. Males had significantly greater indices than females did in regard to dyslipidemias (30.8% vs 18.1%, P<0.001) and to TG (24.7% vs 10.1%, P<0.001). However, a greater prevalence of high LDL-C was observed in females (P<0.001). No relation between sex and hypercholesterolemia was observed (tab. III).

A clear influence of the census sector on dyslipidemias, and, consequently, of familial income, was observed, and it was more evident in individuals living in the poorest areas (P<0.001). However, the greater prevalence of hypertriglyceridemia was observed in the sectors whose income lay between 2 and 10 minimum wages.

Table III also shows the lack of influence of ethnicity, educational level, and smoking on the lipid profile. A certain familial tendency was observed in regard to dyslipidemias (P=0.01), as in regard to isolated values of LDL-C and TG.

Reference to a sedentary lifestyle showed a correlation with increasing levels of TG (P=0.02), and overweight also showed a correlation with dyslipidemias (TC, HDL-C, and TG). Abdominal fat build up, translated as an increase in the waist circumference, was positive in determining elevated indices of TC (P=0.03) and TG (P<0.001). Individuals with associated comorbidities, such as high blood pressure and diabetes mellitus, had a greater prevalence of dyslipidemias (P<0.001).


The overall prevalence of dyslipidemias was high, affecting approximately 1 in every 4 adults (24.2%) in Campos dos Goytacazes. This is alarming in face of the evident relation between dyslipidemias and atherosclerotic disease 35. Studies determining the prevalence of dyslipidemia in specific locations are scarce. Martins et al 36,37 reported indices of 53.4% and 21.3% in the city of Cotia, in the state of São Paulo, in 1989 and 1996, respectively. High lipid levels are predictive of consequent cardiovascular mortality in the near future in the population assessed. Stratifying dyslipidemias in males and females, a significant relation with the male sex (30.8 vs. 18.1, P<0.001) was observed. This fact may determine the greater incidence of atherosclerotic disorders in males.

Through distribution according to age groups, a significant increase in the prevalence of dyslipidemias, hypercholesterolemia, and alterations in LDL-C and HDL-C was observed (P<0.001). This did not occur with hypertriglyceridemia, which was relatively constant from the fourth decade onwards. The high percentages in the advanced age groups result in a greater number of individuals with cardiovascular diseases, due to the increase in the world's elder population 18,38.

Of the lipid parameters, total cholesterol was the most assessed in the studies published so far, and it had a wide range of variation. In the city of Campos dos Goytacazes, the prevalence of high lipid levels was 4.2%, and that of borderline levels was 19.6%. No variation according to sex was observed. North American studies report a prevalence of 18.9% 39. Nicolau et al reported a prevalence of high lipid levels of 16% in individuals older than 29 years in the city of São José do Rio Preto in 199112, and of 7.9% in individuals older than 20 years in 1997 40. Duncan et al 16 reported 14.9% in the city of Porto Alegre. Gus et al 38 reported 5.6% in the Brazilian state of Rio Grande do Sul. Guimarães and Lima 41 reported 18% in a population in the state of Bahia, and Rouquayrol et al 42 reported 6.3% (³ 250 mg/dL) in the city of Fortaleza. The III Brazilian Guidelines on Dyslipidemias mentions a study carried out in 9 Brazilian capitals, which determined a prevalence of 8.8% 43. Souto Filho et al 13, using laboratory samples, estimated a prevalence of 14.3% in the northern and northwestern regions of the state of Rio de Janeiro and of 6.9% in the city of Campos dos Goytacazes. When compared with other locations, the latter city has 1 of the lowest prevalences of hypercholesterolemia.

A significant influence of age on lipid levels was observed. Among males, mean cholesterol was more elevated in the age group from 40 to 49 years, and decreased in older individuals. Among females, this maximal elevation occurred later, in the age group from 60 to 69 years. Similar variations were found in other studies 12,16,18,39. The reduction in the mean and in the prevalence of high levels in individuals older than 70 years should be due to the longer survival of those without dyslipidemias 18. Comparing the sexes, the mean values were higher in males up to the fifth decade, but, from this age onwards, females had the higher levels. This fact stresses the influence of estrogen on lipid profile.

High and very high levels of LDL-C were found in 3.5% of the population and borderline levels in 9.6% 1. This fact shows the need to determine targets to reduce the risk of coronary events in 13.1% of the adult population, both through changes in lifestyle and pharmacological therapy. Studies on specific populations, such as individuals with coronary artery disease, have reported risks of 14.8% 11 and 38.5% 22, but in a laboratory sample the risk was 31.1% 15. Alterations in LDL-C levels predominated in the female sex (4.2% vs 2.5%, P=0.02), different from the North American findings 39 (males, 20.4%; females, 17%).

The mean population levels of cholesterol in all age groups and both sexes were within optimum values (< 200 mg/dL). This fact did not occur in the evaluation of LDL-C, whose means were always within desirable levels (100-129 mg/dL), except for males between 18 and 29 years, who had optimum values (< 100 mg/dL). In a population with mean normal cholesterolemia, LDL-C levels may be high, showing the actual need for studies encompassing the entire lipid profile, because LDL-C is an independent causal factor of atherosclerosis and an element that determines the targets for the treatment of dyslipidemias 1.

The incidence of HDL-C levels lower than 40 mg/dL was 14.3%. The alteration in the reference value, according to new recommendations 1, generated some difficulties in the comparison with previous studies. Low HDL-C levels corresponded to the second most frequent dyslipidemia in the city of Campos dos Goytacazes, and it was significantly greater in males (18.3% vs 8.9%, P<0.001). The mean HDL-C levels were relatively constant (between 48.9 and 47.3 mg/dL) in individuals older than 30 years, similarly to that which was reported in other population groups 11,40,44 , and more elevated when compared with those of patients with coronary artery disease 22,29. In the male sex, the mean values remained relatively constant with aging, ranging from 46.8 to 47.7 mg/dL from the third decade onwards. On the other hand, in females, a mean above 50 mg/dL was observed until the age group from 50 to 59 years. More elevated HDL-C levels in the female sex has also been reported in other publications 28,45. However, from the fifth decade onwards, an important drop in the HDL-C levels has been reported and has been directly related to an increase in the risk of coronary artery disease in females at an advanced age 46.

With a prevalence of 17.1%, hypertriglyceridemia was the most prevalent dyslipidemia. The levels were consistently greater in the male sex, with a greater mean (168.7 vs 133.0 mg/dL) and prevalence (24.7% vs 10.1%, P<0.001). More elevated levels in both sexes were found in the sixth decade, being followed by a reduction in older individuals.

When stratifying individuals into Caucasian and non-Caucasian, the correlation between lipid alterations and ethnicity could not be determined. No variation in the lipid levels of individuals with a high or low educational level was observed.

The prevalence of dyslipidemias and hypercholesterolemia was significantly different when the social strata were compared. Levels of 33.3% were detected in socioeconomic levels of up to 1 MW, and a reduction in the indices was observed as familial income increased. This same correlation was also present in the evaluation of TC, LDL-C, HDL-C (P<0.001), and TG (P<0.01). These results disagree with those of Rouquayrol et al 42, who, evaluating the population of the city of Fortaleza, reported greater hypercholesterolemia indices (14.1% vs 2.8%) in individuals living in mansions as compared with those living in shantytowns. On the other hand, Rose and Marmot 47 reported concordant data between morbidity and mortality due to cardiovascular disease and lower socioeconomic classes.

The indices of dyslipidemias in individuals with a positive familial history were 35.2% versus 26.7% (P=0.01). A similar correlation was observed in regard to the elevation in LDL-C and triglycerides. Some studies 29,48 have determined a familial influence in the origin of dyslipidemias, because the individuals are exposed to common environmental factors or because of a direct genetic predisposition.

No difference in the lipid levels of smokers and nonsmokers was observed. Although some studies 1,49 have shown an association between smoking and a reduction in HDL-C levels, this was not a significant factor in our study (smokers, 18.3%, and nonsmokers, 15.2%, P=0.2). This may have resulted from the fact that all individuals who smoked were classified as smokers, independent of the tobacco load.

In regard to sedentary lifestyle, the only significantly increased lipids were triglycerides (P=0.02). Sedentary lifestyle plays a significant role as a risk factor for atherosclerosis 1,50, and changes in lifestyle with the introduction of physical exercise are essential for prevention and treatment of atherosclerosis 1,51. The impact of physical activity occurs mainly in the form of a reduction in triglyceride levels and an increase in HDL-C 1,52. However, no relevant differences were observed between the HDL-C levels in individuals with sedentary and nonsedentary lifestyles, and this was also reported by Sartori et al 28.

A correlation between the dyslipidemias and overweight and obesity (P<0.001) was observed. Cholesterol levels were significantly elevated in overweight individuals (overweight + obesity) (P=0.04). On the other hand, high LDL-C levels had a greater association with obesity (P=0.04) as compared with those of total cholesterol (p=NS). In obese individuals, the particles of LDL-C are smaller and denser, inducing the more intense formation of fat cells 1,53. The major dyslipidemias observed in obese individuals were hypertriglyceridemia (P<0.001) and the reduction in HDL-C (P=0.02), in accordance with other studies 54-57.

The build-up of abdominal fat characterized by central or androgenic obesity results in a greater risk for atherosclerosis 1,34,58. Those individuals had a greater prevalence of dyslipidemias, hypercholesterolemia, and hypertriglyceridemia (tab. III). The abdominal fatty tissue has a greater metabolic activity, releasing large amounts of free fatty acids that cause an increase in triglycerides 55. At the same time, no change in LDL-C and HDL-C levels was observed.

Blood pressure levels > 140x90 mmHg correlated with greater indices of dyslipidemias, hypercholesterolemia, and hypertriglyceridemia, and lower HDL-C levels. This association has also been reported in some studies in regard to high levels of cholesterol 12,59 and non-HDL-cholesterol 59. No change in LDL-C was observed with increased blood pressure. These results suggest a biological interrelation between blood pressure and blood lipids, and, consequently, an association with the risk for atherosclerosis.

Diabetes mellitus was present in 16.2% of the individuals with any type of lipid alteration, being an important cause of secondary dyslipidemias. In diabetic individuals, significantly more elevated prevalences of dyslipidemias, hypercholesterolemia, and hypertriglyceridemia were observed, as were low HDL-C levels (P<0.001) and high LDL-C levels (P=0.03). The lipid abnormalities in diabetic individuals are consequent to insulin resistance and manifest as hypertriglyceridemia and low HDL-C levels 60, in accordance with the results obtained.

The dyslipidemias were more frequent than expected, and routine investigations are required for early diagnosis in asymptomatic individuals. The accurate determination of the prevalence of dyslipidemias allows adequate planning of health actions for primary and secondary prevention of cardiovascular disorders in the population of Campos dos Goytacazes. Therefore, broader population studies are required to determine not only regional characteristics, but also the national lipid profile.
