Abstract: Objective To investigate the different prevalence of ideal cardiovascular（CV）health behavior and factors in Kailuan cohort with different age and gender. Methods A cross-sectional study was designed in this research. From 2010to 2011,totally 105 697Kailuan Group employees who underwent general health survey or physical examination were collected and finally 83 821qualified subjects were included for analysis. These cases were free of stroke,malignant tumor,pregnancy and lactation,and incomplete examination data. Based on their ages,this cohort was divided into three groups:youth group（aged 18-＜40）,middle-aged（aged 40- ＜65）,elderly group（aged≥65）. And the age and gender differences in the prevalence of ideal CV health behavior and factors were probed. Results Ideal smoking status occupied the highest proportion in each age group,and it was higher in females than in males. Meanwhile,the ideal physical activity status was the lowest among all CV health behavior. But it increased with age,and the elderly group shared the highest. The status of ideal CV health factors in different gender and age groups was as follows:the ideal status ratio up with increased age in the three CV factors of physical exercise and smoking. Female at all ages had higher prevalence of ideal blood pressure than male counterpart did. The median levels of CV health factors with different ages and sexes were demonstrated as below:in both genders,the indexes of body mass index,systolic pressure,fasting blood-glucose and total cholesterol levels reached the median levels of ideal group if the lowest quartiles of these indexes in ordinary group reduced by2.7kg/m2,10mm Hg,1.1mmol/L,1.0mmol/L respectively. Additionally,these indexes hit the median of ordinary group if the lowest quartiles in subordinate group decreased by 3.0kg/m2,20mm Hg,1.1mmol/L,and0.9mmol/L respectively. Conclusion There are significant gender and age differences in the seven ideal cardiovascular health behavior and factors.
