[Study on the distribution of prevalence of hypercholesterolemia and borderline high cholesterol in Chinese adults].
OBJECTIVE
To study the distribution of prevalence on hypercholesterolemia and borderline high cholesterol of Chinese residents aged 20 years and above.


METHODS
To detect the total fasting plasma cholesterol in 48 299 subjects among 20 year-olds and above.


RESULTS
Within a certain age range, the prevalence of both hypercholesterolemia and borderline high cholesterol increased with age, but there was a decreasing trend after 60-years of age in some regions. The prevalence of hypercholesterolemia increased to 12.53% in over 70 year-olds group from 1.36% in urban 20-year-olds, and increased to 5.15% from 60-year-olds group comparing to 0.98% of the 20-year-old group in rural areas. When comparing to the 20-year-old age group, the prevalence of borderline high cholesterol of the 70 age group in urban and rural increased by 4.4 and 4.2 times, respectively. The prevalence of hypercholesterolemia in each age group in urban were higher than that of in rural areas. In Rural I, it was higher than that of in Rural II , Rural III and Rural IV. The prevalence rates of both hypercholesterolemia and borderline high cholesterol of the males in the less than 50 year-olds group were higher than that in females, which was quite different from the group older than 50 years of age. As to borderline high cholesterol, similar result was also noticed.


CONCLUSIONS
Within a certain age range, there was a trend that the prevalence of both hypercholesterolemia and borderline high cholesterol increased with age and related to regions which were classified by economic status. A distinct difference between males and females also existed.
