Abstract:
Objective To explore influencing factors of all-cause mortality in adults aged 55 years and over in Beijing city.
Methods Cox proportion hazard regression model was used to analyze the influencing factors of all-cause mortality.
Results Female adults had a decreased risk of death than male adults(relative risk
RR=0.543,95% confidence interval95%
CI=0.434-0.678).The risk of cardiovascular diseases(CVD)mortality increased sharply with age,and the adults with hypertension(
RR=1.348,95%
CI=1.145-1.588),hyperglycemia(
RR=1.512,95%
CI=1.278-1.789),disability(
RR=1.327,95%
CI=1.129-1.559),a self-assessment of unhealth(
RR=1.194,95%
CI=1.006-1.416),and illiteracy(
RR=1.644,95%
CI=1.133-2.386)had significantly increased risk of CVD death.Mortality in rural adults was significantly lower than in adults of mountain villages(
RR=0.666,95%
CI=0.539-0.840).
Conclusion With disability,self-assessment of unhealth,hyperglycemia,hypertensive,and illiteracy are risks factors for all-causes death among adults aged 55 years and older in Beijing city.
