title: [Serum insulin and lipids in high school adolescents in Guadalajara, Mexico].
abstract: OBJECTIVE
  To determine the serum concentration of insulin and lipids among high school students, according to age, sex, and socioeconomic level.
  
  
  METHODS
  A cross-sectional study was carried out between October 1998 and March 1999 among 352 high school students aged 14-19 years in Guadalajara, Mexico. Insulin, total cholesterol, triglyceride, high-density lipoprotein (HDL), low density lipoprotein (LDL), and very low density lipoprotein (VLDL) levels were measured. Student's t test, chi-squared tests, and ANOVA, were used to compare mean measurements and proportions.
  
  
  RESULTS
  Mean values were obtained for insulin (54 +/- 30 pmol/l); triglycerides (101 +/- 36 mg/dl); total cholesterol (157 +/- 27 mg/dl); LDL (95 +/- 26 mg/dl), and HDL (44 +/- 9 mg/dl).
  
  
  CONCLUSIONS
  Total cholesterol, LDL, and HDL levels were higher among females. Hol levels were lower in low socioeconomic level. Insulin levels were higher among younger subjects.
