[Sero-epidemiologic study on the relationship between Chlamydia pneumonia infection and hypertension in Chinese Mongolian population].
OBJECTIVE
To explore the relationship between Chlamydia pneumonia (CP) infection and hypertension as well as the interaction of traditional risk factors and CP infections on hypertension in Chinese Mongolian population.


METHODS
1430 inhabitants living in Tongliao city, Inner Mongolia were selected as research subjects, including 488 hypertensives and 942 normotensives. Enzyme-linked immunoassay technique was used to test CP IgG antibody in the blood serum and SPSS 13.0 Microsoft was used to analyze the data.


RESULTS
The prevalence rates of hypertension were significantly different between CP IgG positive and negative groups, However, the trend was attenuated after adjusting age, sex, drinking, smoking, body mass index (BMI) and dyslipidemia. The CP infection rate was significant different in diastolic blood pressure groups, which was significantly higher in 80-84 mm Hg than that in the lowest DBP group. The interaction of chronic CP infection and other traditional risk factors were associated with hypertension in Chinese Mongolian ethnic groups. The ranking with significant sequence from high to low were BMI, dyslipidemia, alcohol intake, sex and age.


CONCLUSIONS
CP infection was not related to hypertension in Chinese Mongolian ethnic groups but the interaction with other traditional risk factors would increase the risk of developing hypertension.
