A cada sujeto se le determinó peso y talla y se le tomó una muestra de 5 mL de sangre en ayunas. Se definió sobrepeso como índice de masa corporal (IMC)>25 y <30, obesidad como IMC>30 e hipercolesterolemia como colesterol total sérico >200 mg/dL.
Resultados: las prevalencias de obesidad y sobrepeso fueron 17,9% y 46,8%, respectivamente. Se encontró 123 (34,7%) sujetos con hipercolesterolemia. Las proporciones de sujetos con valores anormales de colesterol fueron: para HDL-C 0,0%, LDL-C 29,7%, triglicéridos 19,5%, CT/HDL-C 24,9% y LDL-C/HDL-C 16,7%. El sexo masculino, la edad mayor de 50 años y la condición de sedentario estuvieron asociadas con obesidad (p<0,05). El sexo masculino y la edad mayor de 40 años estuvieron asociadas con valores anormales de lípidos séricos. Los valores de colesterol total, LDL-C, triglicéridos, CT/HDL-C y LDL-C/HDL-C fueron significativamente mayores en los sujetos obesos (p<0,05). El nivel de HDL-C fue mayor en el grupo con peso adecuado (p<0,05).
Conclusiones: la obesidad e hipercolesterolemia son patologías relevantes en esta población laboral. Se recomienda establecer programas de prevención de factores de riesgo cardiovascular y modificación de estilos de vida en esta población.

SUMMARY
Objective: To determine the prevalence of obesity and hypercholesterolemia in workers of a government institution in Lima - Perú.
Materials and methods: An analytical cross sectional study was performed, evaluating 359 workers who went to their annual medical check-up between October and December 2001. Weight and height were measured in each subject, and a 5 mL fasting blood sample was taken. Being overweight was defined as a body mass index (BMI) >25 and <30, Obesity as a BMI>30, and hypercholesterolemia as total cholesterol (TC) >200 mg/dL.
Results: The prevalence of obesity and being overweight was 17,9% and 46,8%, respectively. Hypercholesterolemia was found in 123 (34,7%) subjects. The rates for abnormal cholesterol values were as follows: HDL-C, 0,0%; LDL-C, 29,7%; triglycerides, 19.5%; TC/HDL-C, 24,9%, and LDL-C/HDL-C, 16,7%. Masculine sex, age greater than 50 years and sedentarism were associated with abnormal values for serum lipids. TC, LDL-C, and triglyceride values, as well as TC/HDL- C and LDL-C/HDL-C rates were significantly higher in obese subjects. However, HDL-C values were higher in the group of subjects with an adequate weight.
Conclusion: Obesity and hypercholesterolemia were relevant conditions in this working population. We recommend to establish programs for the cardiovascular risk factors prevention and changes in life style in this population.
