Abstract: Background　In China，the mortality of cardiovascular disease is high，and its annual incidence is increasing，but the incidence risk can be reduced by effective comprehensive management and prevention interventions.Appropriate cardiovascular health factors and behaviors are closely associated with cardiovascular disease.However，due to sex-，age-，and regional differences in cardiovascular health factors and behaviors，it is urgently needed to develop targeted health management regimens.Objective　To explore sex- and age-specific differences in cardiovascular health factors and behaviors in community-dwelling populations in Ningxia，providing evidence for the development of health education and management programs.Methods　By use of cluster sampling，2 486 community-dwelling residents undergoing physical examination in Ningxia International Travel Healthcare Center were enrolled in March 2016.General data，including sex，age，laboratory parameters，cardiovascular health factors and behaviors，were collected.Comparisons of laboratory parameters and cardiovascular health factors and behaviors were performed by sex and age group.Results　Men showed greater mean age，SBP，DBP and FPG，but lower mean TC，scores，and number for appropriate health factors and behaviors，rates of non-smokers，physical exercisers（P<0.05）.In men，those aged less than 50 years had better mean blood pressure than those of age groups of 55-59，60-64，65-69 and greater than 70 years（P<0.05）.Those aged 50-54 years had better mean blood pressure than those of age groups of 60-64，65-69 and greater than 70 years（P<0.05）.Those aged less than 50 years had better FPG compared with those of other age groups（P<0.05）.But mean BMI，TC，prevalence rates of smoking and healthy diet were similar across all age groups（P>0.05）.In women，those aged less than 50 years had better mean blood pressure compared with those of other age groups（P<0.05）.Those aged 50-54 years had better mean blood pressure than those of age groups of 65-69 and greater than 70 years（P<0.05）.Those aged 55-59 years had better mean blood pressure than those of age groups of 65-69 and greater than 70 years（P<0.05）.Those aged less than 50 years showed better TC compared with those of other age groups（P<0.05）.Those aged less than 50 years demonstrated better mean FPG than those of 60-64 age group（P<0.05）.The rate of physical exercisers was higher in 50-54 age group than that of 60-64 and 65-69 age groups（P<0.05）.Mean BMI，prevalence rates of smoking and healthy diet were similar across all age groups（P>0.05）.The average number of appropriate cardiovascular indices in women was more than that of men （P<0.001）.The prevalence rate of 5-7 appropriate cardiovascular indices in women was also more than that of men （P<0.001）.Conclusion　In community-dwelling populations in Ningxia，cardiovascular health factors and behaviors present sex- and age-specific differences.To improve the overall cardiovascular health level in these people，cardiovascular health interventions should be delivered to men，a target priority group，and also should be delivered to those aged 50-70 years.
