Implication

Observational study reveals major non-home sources of passive smoking in young adults, indicating external environments contribute significantly to overall secondhand smoke dose.

Key Points

To quantify determinants of environmental tobacco smoke exposure among non-smoking older adolescents living at home using saliva cotinine concentrations.
Measured saliva cotinine concentrations in 393 non-smoking students aged 16 to 19 years attending a sixth form college and living at home.
Assessed self-reported passive smoking exposure over the previous three days across multiple settings, including parental smoking, college environments, and evening social activities.
Median saliva cotinine concentration was 0.60 ng/ml overall and increased across self-reported exposure categories from 0.30 ng/ml ('None at all') to 0.60 ng/ml ('A little'), 0.90 ng/ml ('Some'), and 1.35 ng/ml ('A lot', p < 0.0001).
Significant independent sources of exposure included maternal smoking (p < 0.0001), paternal smoking (p < 0.01), exposure at college (p < 0.001), and exposure during evening outings (p < 0.001).
