Abstract: Objective To compare the correlation between halitosis and metabolic index in health examination subjects. Methods 2 885 health examination people were selected. Body weight, height, blood pressure, blood glucose, cholesterol, triglyceride, low density lipoprotein, high-density lipoprotein and uric acid were included in the analysis. Examination of the patient's halitosis, comparison of metabolic markers in patients with and without halitosis, in addition, the performance of halitosis group were analyzed. Results Men had a higher proportion of bad breath(P<0.01). The metabolic indexes, including body mass index, systolic blood pressure, diastolic blood pressure, fasting blood glucose, total cholesterol, triglyceride, low density lipoprotein and uric acid, were higher than those in the control group. The high density lipoprotein in the halitosis group was lower than that in the halitosis group. Bad breath of patients with halitosis was obviously stronger. Their mean levels of metabolism were lower than those in the halitosis group, which were higher in the breath group than in the halitosis group, except for that HDL average decreased. Conclusion There is a homogeneous relationship between halitosis and metabolic abnormalities. There is a correlation between the two.
