ABSTRACT

Objective To investigate the prevalence of cervical spondylosis among adults in Beijing.Methods The prevalence of cervical spondyiosis among people older than 18 years who had lived in Beijing for more than six months was investigated in December 2010.The multi-stage sampling was used in this cross-sectional study.The related information was obtained by a self-designed questionnaire.Single and muhivariable Logistic regression models were applied to analyze high risk districts and populations.Results A total of 3859 people were enrolled in this study.Among them there were 531 people with cervical spondylosis,and the prevalence was 13.76％.The prevalence of cervical spondylosis in suburb (15.97％) was the highest compared with city center and countrysides (x2=8.257,P=0.016).The prevalence in females (10.49％) was higher than that (16.51％) in males (x2=29.432,P＜0.001).The distribution of prevalence among different age populations was inverted U shape,and the prevalence was higher in 45 years group (20.43％) and 60 years group (18.91％) compared with other two groups.The prevalence in employed group was 1.303 times higher than that in unemployed group (95％CI:1.008,1.684).According to the muhivariable logistic regression result,suburb (OR=1.306,P=0.026),females (OR=1.81 1,P＜0.001),people who were 45years or 60 years (OR=2.171,P＜0.001; OR=2.430,P＜0.001,respectively) and employed and retired people (OR=1.664,P=0.001; OR=1.303,P=0.043,respectively) were high risk population of cervical spondylosis.Conclusion The prevalence of cervical spondylosis among adults in Beijing was much higher and vastly distributed.It's necessary to reinforce the prevention,diagnosis and treatment study.Young females,people aged 45 years or 60 years,and employed people were high risk populations.
