Effect of interaction between blood lead and blood cadmium levels on odds of Hepatitis B seropositivity, NHANES 1999–2012
| Blood lead levels | Blood cadmium levels | ||||
|---|---|---|---|---|---|
| <Median | ≥Median | AOR (95 % CI) within Pb strata | |||
| N (Weighted %) | AOR (95 % CI) | N (Weighted %) | AOR (95 % CI) | ||
| <Median | 4160 (2.2) | 1.0 | 3622 (4.5) | 1.51 (1.12–2.04) | 1.42 (1.03–1.98) |
| P | P = 0.0310 | ||||
| ≥Median | 3011 (4.0) | 1.23 (0.86–1.76) | 6596 (7.9) | 1.98 (1.51–2.61) | 1.67 (1.23–2.25) |
| P = 0.2503 | P = <0.0001 | P = 0.0008 | |||
| AOR (95 % CI) within Cd strata | 1.12 (0.79–1.60) | 1.35 (1.06–1.72) | |||
| P = 0.5209 | P = 0.0155 | ||||
Measure of interaction on additive scale: RERI (95 % CI) = 0.24 (−0.28–0.76)
Measure of interaction on multiplicative scale: ratio of ORs (95 % CI) = 1.07 (0.71–1.61); P = 0.7622
AORs are adjusted for age, gender, race/ethnicity, country of birth origin, family income, self-reported general health condition, use of illicit/street injected drugs
