[Global disease burden of neonatal jaundice from 1990 to 2019]

To examine the global, regional, and national disease burden of neonatal jaundice.

The 2019 Global Burden of Disease database was searched to collect incident cases/incidence and deaths/mortality of neonatal jaundice, as well as global socio-demographic index (SDI) and universal health coverage index (UHCI). The epidemiological trend of neonatal jaundice from 1990 to 2019 was analyzed. The correlations between incidence/mortality of neonatal jaundice and SDI and UHCI were evaluated.

From 601 681 in 1990 to 626 005 in 2019, with a 4.04% increase in global incident cases of neonatal jaundice. The overall age-standardized incidence rate exhibited an increase [estimated annual percent change=0.13 (95%CI: 0.03 to 0.23)] during this period. Additionally, deaths due to neonatal jaundice decreased by 58.83%, from 128 119 in 1990 to 52 742 in 2019. The overall age-standardized mortality rate showed a decrease [estimated annual percent change=-2.78 (95%CI: -3.00 to -2.57)] over the same period. Countries with lower SDI, such as India, Pakistan, and Nigeria, reported a higher proportion of neonatal morbidity and mortality. In 2019, a negative correlation was observed between estimated annual percent change in age-standardized mortality rate and SDI (ρ=-0.320, P<0.05) or UHCI (ρ=-0.252, P<0.05).

The global incidence of neonatal jaundice is on the rise, while the mortality rate is declining. The burden of neonatal jaundice is influenced by social development, economic factors, and the level of medical care.
