TABLE 2.

Association between bone lead measured in tibia and patella^* and prevalent abnormal responses on mood dimension scores (n = 744), VA Normative Aging Study, United States, 1991–2002

Mood dimension score^†	Tibia OR	95% CI	Patella OR	95% CI
Anxiety	1.18	0.98, 1.42	1.18	0.98, 1.41
Depression	1.16	0.97, 1.38	1.11	0.92, 1.33
Hostility	1.12	0.91, 1.38	1.13	0.93, 1.39
Phobic anxiety	1.13	0.90, 1.41	1.24	0.99, 1.55
Somatization	1.21	1.01, 1.46	1.09	0.90, 1.32
Global Severity Index	1.15	0.96, 1.38	1.23	1.02, 1.47
Positive Symptom Total	1.09	0.91, 1.31	1.11	0.92, 1.34
Positive Symptom Distress Index	1.08	0.90, 1.29	1.06	0.89, 1.26

Reported are odds ratios (ORs) and 95% confidence intervals (CIs) corresponding to an interquartile increment in both tibia lead (14 µg/g) and patella lead (20 µg/g).

All analyses were adjusted for age at bone scan, alcohol consumption (categorical), education (categorical), time between Brief Symptom Inventory assessments, and cumulative smoking (pack-years).
