Statistical Analysis
Mean levels of total, LDL, and HDL cholesterol and triglycerides
were determined for the overall population and by age group for men
and women. Next, mean levels were determined for men and women
by region (urban and rural and north and south, separately) after age
standardization to the overall year 2000 population of China. The
prevalence estimates of total, LDL, and HDL cholesterol categories
were calculated for the overall population and by age group. In
addition, prevalence estimates were calculated for men and women,
for north and south, and for urban and rural areas separately after age
standardization.
