Trends in Incidence of Urinary Tract Infection in Mainland China from 1990 to 2019.

PURPOSE

Urinary tract infection (UTI) is the second-most-common type of infection in China. This study aimed to determine the long-term trends in the incidence of UTI in Mainland China between 1990 and 2019.

MATERIALS AND METHODS

Data were extracted from the Global Burden of Disease Study 2019 and were analyzed with the age-period-cohort framework.

RESULTS

The net drift in the incidence of UTI was -0.37% (95% CI: -0.40%, -0.35%) in males and -0.25% (95% CI: -0.29%, -0.20%) in females. For males, the local drift was lower than 0 (P<0.05) among those younger than 90 years. For females, the local drift was lower than 0 (P<0.05) among those younger than 60 years and higher than 0 (P<0.05) in those aged 65-79 years. In the same birth cohort, the incidence of UTI was higher in females than in males in all age groups (P<0.05). The period relative risk (RR) showed a decreasing pattern after 2005 in both sexes. The cohort RR showed a downward trend of the birth cohort after 1905 for males and 1960 for females.

CONCLUSION

The incidence has increased significantly among older females over the past 30 years. It is necessary to develop a comprehensive intervention plan for reproductive health services covering females and males of all ages.
