Abstract

Background
This study aimed to investigate the association between the exposure to secondhand smoke (SHS) and dysglycemia.
Methods
This cross-sectional study included a total of 4,417 adults (1,103 with SHS exposure, 3,314 without it) aged 19 years old or older, using data from the 7th Korean National Health and Nutrition Examination Survey. Exposure to SHS at home and/or at workplace and/or public space was assessed by a self-reported questionnaire and corroborated by urine cotinine levels. In addition, the SHS group subjects were subdivided into five groups according to the urine cotinine level. The associations between SHS and dysglycemia (fasting blood glucose ≥100 mg/dL or HbA1c ≥5.7%) were examined using logistic regression analyses.
Results
After adjusting for covariates, the SHS group showed higher odds ratio for dysglycemia than the non-exposed SHS group, although the relationship was not significant (odds ratio, 1.176; 95% confidence interval, 0.985–1.405; P=0.074). The SHS group showed a higher fasting plasma glucose level in men than the non-exposed group (odds ratio, 1.274; 95% confidence interval, 1.014–1.600; P=0.038). In addition, the risk of dysglycemia was high in subgroups of higher urine cotinine concentration in the SHS group.
Conclusion
Dysglycemia is correlated with the degree of exposure to secondhand smoke.
