Objectives

To examine the feasibility of telephone-assisted placement of air nicotine monitors among low socio-economic intervention participants, and examine the use of this strategy in differentiating air nicotine concentrations in rooms where smoking is allowed from rooms where smoking is not allowed.

Methods

Forty participants were recruited from a county health department clinic and were enrolled in a brief smoke-free home policy intervention study. Twenty participants were selected at random for air nicotine monitor placement, and were instructed to telephone study staff who assisted them in monitor placement in their homes at the end of the intervention. Assessments were conducted at Weeks 0 and 8, with air nicotine assessment performed post-test.

Results

Of the 20 participants, 17 placed and returned the air nicotine monitors, and 16 also completed the follow-up survey. Follow-up survey data were not obtained on one monitor, and one participant who did not return the monitor completed the follow-up survey. Among those who reported a smoke-free policy (n=7), the average nicotine concentration was 0.62 μg/m3 [standard deviation (SD) 0.48]. Among those without a smoke-free policy (n=9), the average nicotine concentration was 2.30 μg/m3 (SD 2.04). Thus, the air nicotine concentration was significantly higher in those rooms where smoking was allowed [t(9, 11)=-2.39, P=0.04].

Conclusions

The use of a telephone-assisted protocol for placement of air nicotine monitors was feasible. Despite the variability of air nicotine concentrations in rooms where smoking is allowed compared with rooms where smoking is not allowed, average concentrations were lower in smoke-free rooms.
