Prevalence of microalbuminuria stratified by age in 10 intervals. Figure 5 shows that in age stratification by 10 intervals, except for age < 40 years, the female subjects had a higher prevalence of microalbuminuria than the male subjects no matter what age group they were in. Furthermore, It could also be found that the prevalence of microalbuminuria increased with age, both in male (except for age < 40) and female participants.
