We carried out an exploratory analysis of the contribution of the underlyingstellar absorption to the total uncertainty of the abundance of primordialhelium using simple stellar populations models and observational data from theSloan Digital Sky Survey. Results indicate that our analysis yields a lowerlimit to the error on the helium abundance determination if the stellarabsorption is neglected.
