AB  - BACKGROUND: Little is known about factors affecting participation in 
      population-based biomonitoring studies. We analyzed socioeconomic factors 
      influencing participation in the Barcelona Health Survey (BHS) study on the 
      distribution of serum concentrations of persistent organic pollutants (POPs). 
      METHODS: After completing the BHS personal interview at home participants aged 
      >or=15 years were invited to donate blood. Conducted on a different date and 
      location, the POPs study included additional questions, blood extraction, and a 
      brief physical examination. Factors influencing participation were analyzed by 
      logistic regression. RESULTS: Of 523 BHS participants that we contacted to 
      participate in the study, 231 (44%) participated; they were broadly 
      representative of the city population regarding sex, birth place, body mass index 
      (BMI), employment status and occupational social class. Participants in the POPs 
      study had higher educational level and family income. Controlling for 
      confounders, participation was slightly higher among women than men (odds ratio 
      [OR]=1.38, p=0.02), and lower among the youngest and oldest subjects (p=0.002), 
      with a strong and monotonic trend of increasing participation with increasing 
      educational level (p<0.001) (OR for university level vs. no studies=4.58, 95% CI: 
      2.3-9.3). CONCLUSIONS: Although participation was somewhat low, participants were 
      similar to the city population regarding sex, BMI, birth place, employment, and 
      occupational social class. Health surveys that integrate environmental biomarkers 
      should invest specific resources to encourage participation of the youngest and 
      oldest individuals, and of those with more disadvantaged socioeconomic position 
      (particularly, citizens with lowest education).
