Aim: The present study aimed to determine the up-to-date prevalence, awareness, treatment, and control of dyslipidemia, and their distribution and related influencing factors in adults in Beijing, China.
Method: A cross-sectional study was conducted in 2008, using a four-stratified cluster sampling. Data from a questionnaire, physical examination, and blood sampling were obtained from 5761 adults aged 18-79 years.
Results: The prevalence of high TC, high LDL-C, low HDL-C and TG was 12.2%, 17.9%, 12.0% and 15.1%, respectively. The prevalence of dyslipidemia was 35.4% (42.9% in men and 30.1% in women), and was similar in rural (35.3%) and urban (35.8%) areas. Dyslipidemia was associated with male gender, age, a family history of dyslipidemia, education at college or above, current smoker, overweight and obesity, intermediate and high waist circumference, hypertension and diabetes. Among all participants with dyslipidemia, 22.2% were aware of the diagnosis, 10.2% were receiving treatment, and 3.8% had dyslipidemia controlled. The proportion of those aware of their condition and those who were treated increased with age in both sexes. Of those aware of their dyslipidemia, 46.1% were on treatment, 51.0% had modified their lifestyle, and 24.5% were not receiving treatment or modifying their lifestyle.
Conclusions: The major type of dyslipidemia in Beijing is high LDL-C rather than high TG. The prevalence of dyslipidemia is similarly high in rural and urban areas, with low awareness, treatment and control. A comprehensive strategy toward the prevention, screening, treatment, and control of dyslipidemia is needed to slow the epidemic of cardiovascular disease.
