title: [Prevalence of dyslipidemias in adults in laboratory tests from Salvador, Brazil].
abstract: OBJECTIVE
  To determine the prevalence of dyslipidemia in non-hospital laboratory tests of adults from Salvador, Brazil.
  
  
  METHODS
  The study was carried out in subjects from a probabilistic sample of 25% of a total of 104 local laboratories that used the same enzymatic method for lipid analysis with the quality control as recommended by the Brazilian Society of Clinical Analyses. These represented 93% of all non-hospital laboratories of Salvador in 1995. The odd months of 1995 were selected for sampling in the present study. Criteria for dyslipidemias were: total cholesterol > or = 240; LDL > or = 160; HDL < 35 and triglycerides > or = 200 mg/dl. Prevalence rates and their 95% confidence intervals (CI) and chi 2 test were used in the analyses.
  
  
  RESULTS
  Tests from two of the 26 laboratories were not used in the analyses due to file problems or refusal. 7,392 adults were screened, 65% female. We observed prevalence (95% CI) of hypercholesterolemia in 30.0 (27.8; 32.2)%, high LDL in 30.1 (30.8; 35.4)% and hypertriglyceridemia in 30.4 (29.0; 31.4)% of the females. As to the male subjects, prevalences were; 24.0 (20.5; 27.5)% for hypercholesterolemia, 26.1 (22.4; 29.3)% for high LDL, 27.6 (25.7; 29.5)% for hypertriglyceridemia. All gender differences were significant. Low HDL occurred in 15.9 (14.2; 17.8)% of males and in 8.0 (7.1; 8.9)% of females.
  
  
  CONCLUSIONS
  Dyslipidemia is an important risk factor observed in non-hospital laboratory tests of men and women in Salvador. Our data may provide physicians and other health care professionals with objective information to encourage life-style changes.
