RESUMOObjetivo: Determinar a prevalência de diabetes mellitus (DM) e fatores de risco em adultos, em Campos dos Goytacazes. Métodos: Estudo transversal, de base populacional, com amostragem por conglomerados, estratificada pelo nível sócio-econômico. Foram realizadas duas visitas a 1039 indivíduos, com aplicação de questionário, avaliação da pressão arterial, medidas antropométricas e coleta de amostra de sangue em jejum para análise da glicose, triglicerídeos, colesterol, HDLc e LDL-c. Resultados: A prevalência ajustada pela idade foi de 6,0%. Homens (6,3%) e mulheres (5,7%) tiveram resultados semelhantes, assim como brancos (5,9%) e não brancos (6,3%). A prevalência de DM foi maior em pessoas com história familiar da doença (p<0,001). A prevalência de DM aumentou de 2,1% na faixa de 18-29 anos para 18,3% nos pacientes acima de 70 anos de idade (p<0,001). O DM foi mais prevalente entre os pacientes portadores de hipertensão arterial, dislipidemia e excesso de peso (p<0,001 Objective: To determine the prevalence of diabetes mellitus (DM) and risk factors in adults of Campos dos Goytacazes, RJ. Methods: A crosssectional study of a populational basis was performed, with sample conglomerates stratified by social and economical levels. Two visits were performed to 1039 individuals, with application of a questionnaire, evaluation of the arterial blood pressure, anthropometric measurements and collection of fasting blood for glucose, triglycerides, cholesterol, HDL-c and LDL-c. Results: The age-adjusted prevalence was 6.0%. Men (6.3%) and women (5.7%) had similar results, as well white (5.9%) and non-white (6.3%). The prevalence of DM was higher in people with family history of the disease (p<0.001). The prevalence of DM increased from 2.1% in people with 18-29 years to 18.3% in those with more than 70 years of age (p<0.001). DM was more prevalent among patients with arterial hypertension, dyslipidemia and weight excess (p<0.001). Conclusions: The results are similar to prevalence numbers in other regions of Brazil. Thus, we realize the great importance of DM on public health context as a chronic and non-transmissible disease. (Arq Bras Endocrinol Metab 2003;47/1:69-74)

RESUMOObjetivos: Determinar a prevalência de obesidade e sua associação com hipertensão arterial sistêmica (HAS), dislipidemias (DL), diabetes mellitus (DM) e outros fatores de risco cardiovascular. Casuística e Méto-dos: Estudo de delineamento transversal de 1039 adultos ≥18anos da região urbana, amostragem aleatória em estágios múltiplos e conglomerados. Os dados foram obtidos no domicílio, através de questionário, avaliação clínica e coleta de sangue para análise laboratorial. Resultados: A prevalência de obesidade (IMC ≥30kg/m 2 ) foi de 17,8% (IC 95% 15,5-20,1), enquanto que a obesidade abdominal (CA >102cm e >88cm para homens e mulheres, respectivamente) esteve presente em 35,1% (IC 95% 32,2-38) dos entrevistados. A obesidade foi mais freqüente entre as mulheres -20,2% do que entre os homens -15,2% (p= 0,01) e apresentou associação positiva com a idade (p= 0,05), sedentarismo (p= 0,02), HAS (p< 0,001) e DL (p= 0,005). Nos pacientes com e sem excesso de gordura abdominal as freqüências de HAS, DM e DL foram respectivamente de: 57,7% / 32,0% (p< 0,001), 11,8% / 6,4% (p= 0,03) e 32,2% / 24,1% (p= 0,005). Conclusões: A obesidade foi mais freqüente entre as mulheres e aumentou com o avançar da idade. Os indivíduos com obesidade e/ou excesso de gordura abdominal apresentaram maior prevalência de HAS, DM e DL em relação aos pacientes eutrófi-cos. Cross-sectional study of 1039 adults ≥18 years from an urban region, randomly selected in conglomerates and in a multiple stage process. Data were obtained in the household through a questionnaire, clinical evaluation and blood sampling for laboratory analysis. Results: The overall prevalence of obesity (BMI ≥30kg/m 2 ) was 17.8% (CI 95% 15.5-20.1), while abdominal obesity (AC >102cm and >88cm for men and women, respectively) was present in 35.1% (CI 95% 32.2-38) of the interviewees. Overall obesity was more common among women (20.2%) than men (15.2%) (p= 0.01), with a positive association with age (p= 0.05), sedentarism (p= 0.02), SAH (p< 0.001) and DL (p= 0.005). Among the patients with and without excess abdominal fat, the SAH, DM and DL rates were respectively of: 57.7% / 32.0% (p< 0.001), 11.8% / 6.4% (p= 0.03) and 32.2% / 24.1% (p= 0.005). Conclusions: Overall obesity was more common among women and it increased with age. Individuals with obesity and/or excess abdominal fat presented a greater prevalence of SAH, DM and DL, as compared to healthy individuals.

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
