Background
and Aim: Passive cigarette
smoking or environmental tobacco smoke (ETS) exposure is a major public health
concern. Children are the most vulnerable group to ETS exposure. The aim of
this study was to evaluate the relationship between passive smoking and Total
Antioxidant Capacity (TAC) and salivary lipid peroxidation in adolescents.
Materials
and Methods: In this historical cohort study sixty
adolescents aged 12 to 15 years old were selected. The subjects were assigned
into two groups of healthy non-smokers (control) and passive smokers (case) and
they were matched for age and sex. Unstimulated saliva was collected with
spiting method, and then TAC and salivary lipid peroxidation were measured with
FRAP and TBARS methods respectively. Statistical analysis was done usingindependent t-test.
Results:TAC was significantly lower in passive
smokers (1218.8±511.5 µmol) than in nonsmokers (1490.5±379.2 µmol) (p=0.023).
Salivary lipid peroxidation level was higher in passive smokers (14.6±0.6 µmol)
than in nonsmokers (14.4±0.8 µmol) but it the difference was not statistically
significant (p=0.176).
Conclusions:The exposure to
cigarette smoke can cause a reduction in the salivary Total Antioxidant
Capacity.
