Trends in mortality from lower respiratory infections in children under 14 years, 1990-2019: An analysis of the Global Burden of Disease Study 2019.

Background: Lower respiratory infections (LRIs) remain a leading cause of mortality among children, yet previous studies have primarily focused on children under 5 years of age as a whole, with limited research on more specific age groups. This study aimed to analyze the trends in mortality associated with lower respiratory infections (LRIs) among children under 14 years of age from 1990 to 2019, with particular attention to regional and age-specific disparities.

Methods: We collected annual lower respiratory infection (LRI) deaths and mortality rates for six age groups of children under 14 years from 1990 to 2019 using data from GBD 2019.
