title: [Calcium intake and blood lead in women in reproductive age].
abstract: OBJECTIVE
  To evaluate the relation between calcium intake and blood lead levels in women of reproductive age living in Mexico City.
  
  
  METHODS
  Blood lead was assayed in 198 women of 15-48 years of age. By interrogation, the calcium intake was calculated from the frequency of consumption of 11 foods which provide nearly 95% of the intake of calcium in Mexico.
  
  
  RESULTS
  The mean blood lead was 9.71 micrograms/dL (range 1 to 39). We observed a statistically significant decreasing trend between the risk of having blood lead levels exceeding 10 mu/dL and the increase in calcium intake.
  
  
  CONCLUSIONS
  Our study suggests the need to evaluate interventions such as modifications in the consumption of milk, cheese, and other calcium rich foods, and their effect on blood lead levels.
