Cross-sectional association between annual mean residential black carbon and percent difference (95% confidence interval) in serum leptin levels among participants from the MOBILIZE Boston Study
| Annual Mean Residential Black Carbon (µg/m3) | |||||
|---|---|---|---|---|---|
| Continuousa | 0.33 | 0.33–0.39 | >0.39 | Ptrend | |
| Model 1b | 8% (−1%, 19%) | 1.0 (Ref) | −9% (−29%, 16%) | 20% (−8%, 55%) | 0.16 |

a
Expressed as the % difference in leptin levels for an interquartile range (0.11 µg/m3) shift in annual mean residential black carbon;
b
Adjusted for age, sex, race, season, day of week, smoking, alcohol consumption, physical activity, household income, education and neighborhood socioeconomic status.
c
Additionally adjusted for body mass index, diabetes mellitus, hypertension, and hyperlipidemia.
