Outline
To analyze the relationship between smoking status and risk of cardiovascular diseases among Henan Huixian residents.
The baseline survey data and follow-up data of participants aged 30-79 years recruited in Huixian County, Henan, through the China Chronic Disease Prospective Research Project were used. Cox proportional hazard regression models were used to analyze the association between smoking status and risk of cardiovascular diseases.
A total of 59 865 cases were included in the cohort and followed up for a total of 586 851.81 person years (average 9.20 years). We documented 17 142 cases of cardiovascular diseases, 5 959 cases of ischemic heart diseases, 7 717 cases of cerebral infarction and 1 387 cases of intracerebral hemorrhage. The smoking rate of men (65.29%) was much higher than that of women (0.34%). Cox multivariate analysis showed, compared with nonsmokers, current smokers had higher risk of cardiovascular diseases (HR=1.178, 95% CI: 1.118-1.241), ischemic heart diseases (HR=1.291, 95% CI: 1.177-1.417) and cerebral infarction (HR=1.297, 95% CI: 1.203-1.398). Among current smokers, those who smoked more than 20 cigarettes per day or those who started smoking at the age of less than 20 years old had higher risk of cardiovascular diseases, ischemic heart diseases and cerebral infarction.
Smoking can effectively decrease the risk of cardiovascular diseases. It is necessary to strengthen the control and intervention of smoking behavior in order to curb the epidemic trend of cardiovascular disease.
