Association between arsenic exposurea and math and reading scores based on ordinal regression analysis
| Achievement score | Model 11 OR (95% CI) | Model 22 OR (95% CI) | Model 33 OR (95% CI) |
|---|---|---|---|
| Broad math score | |||
| Complete case sample (n=239) | 1.01 (0.99, 1.04) | 1.01 (0.98, 1.04) | 1.01 (1.00, 1.02) |
| Imputed sample (n=310) | 1.02 (1.00, 1.05) | 1.02 (1.00, 1.05) | 1.02 (1.00, 1.04) |
| Broad reading score | |||
| Complete case sample (n=239) | 1.01 (0.98, 1.04) | 1.00 (0.98, 1.03) | 1.00 (0.98, 1.02) |
| Imputed sample (n=310) | 1.01 (0.98, 1.03) | 1.00 (0.98, 1.03) | 1.00 (0.98, 1.02) |
aModeled as specific gravity adjusted urinary arsenic
1Crude
2Adjusted for season, sex, maternal education, household possessions, HOME score, hemoglobin, blood lead concentrations, hair manganese concentrations
3Further adjusting for school clusters; achievement scores divided into tertiles; the OR represents the likelihood of moving from lower to higher tertile of achievement endpoint.
