Abstract

Purpose: We aimed to estimate the burden of UTIs by age, sex, and socioeconomic status in 204 countries and territories from 1990 to 2019.

Methods: We used data from Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 to analyse the incidence, mortality, and disability-adjusted life-years (DALYs) due to UTIs at the global, regional, and national levels. Estimates are presented as numbers and age-standardised or age-specific rates per 100,000 population, with 95% uncertainty intervals (UIs). We further explored the associations between the incidence, mortality, DALYs, and socio-demographic index (SDI) as a proxy for the development status of regions and countries.

Results: In 2019, more than 404.6 million (95% UI 359.4-446.5) individuals had UTIs globally and nearly 236,786 people (198,433-259,034) died of UTIs, contributing to 5.2 million (4.5-5.7) DALYs. The age-standardised incidence rate increased from 4715.0 (4174.2-5220.6) per 100,000 population in 1990 to 5229.3 (4645.3-5771.2) per 100,000 population in 2019. At the GBD regional level, the highest age-standardised incidence rate in 2019 occurred in Tropical Latin America (13,852.9 [12,135.6-15,480.3] per 100,000 population). At the national level, Ecuador had the highest age-standardised incidence rate (15,511.3 [13,685.0-17,375.6] per 100,000 population). The age-standardised death rates were highest in Barbados (19.5 [13.7-23.5] per 100,000 population). In addition, age-standardised incidence, death, and DALY rates generally increased across the SDI.

Conclusions: Our study results suggest a globally rising trend of UTI burden between 1990 and 2019.
