Objective To explore the effect and potentially interactive effects of the family history of coronary heart disease(FHCHD)and lifestyle factors on CHD among essential hypertensive patients and to provide a basis for the prevention and control of CHD in the hypertensive patients with FHCHD.Methods Based on the health profession scientific reaserch project,the baseline data of 43,769 essential hypertension patients from the cardiovascular risk factor surveillance were clolected from June 2012 to March 2014 in China's 220 community health centers(CHCs)in 15 provinces.The multi-variables logistic regression and multiplicative model were used to evaluate the independent effects and interaction risks(ORs)of FHCHD and lifestyles for CHD;and in additive model,the relative excess risk due to interaction(RERI),synergistic effect index(SI)and attributable proportion due to interaction(AP)were calculated as the interaction indices.Result The FHCHD and smoking were significantly associated with increased risk of CHD in essential hypertensive patients(all P<0.05),whereas drinking was associated with a decreased risk of CHD(P<0.05).There was a positive multiplicative and positive additive interaction between FHCHD and smoking on the risk of CHD prevalence(ORs 7.27,RERI 2.70,SI 1.75,and AP 0.37,all P<0.05).FHCHD and lack of exercise were associated with a increased risk of CHD,with ORs of 5.04(P<0.05).Conversely,FHCHD exhibited an inverse interaction with drinking(ORs 3.82,P<0.05)of CHD in essential hypertensive population.Conclusion The FHCHD,smoking and drinking in the essential hypertensive population are independently associated with CHD.FHCHD combined with smoking and lack of exercise has a positive interaction on CHD,but a negative interaction in the FHCHD and drinking on CHD in the essential hypertensive population.These associations suggest that reducing smoking,increasing exercise,and moderate drinking can lower the risk of CHD in the essential hypertensive patients.
