Abstract:
Objective:To depict the long-term trends of prevalence and disease burden of preterm birth from 1990 to 2019.Methods:Data was from the 2019 Global Burden of Disease study. The prevalence rate (%) and disability adjusted life years (DALYs) rate of preterm birth were adopted and were further stratified by sex. China's prevalence rate and DALYs rate were compared with those of high-income, middle and high-income, middle and low-income, and low-income countries, defined by the World Bank. Joinpoint log-linear regression model was used to analyze the trend.Results:In 2019, the prevalence of preterm birth in China was 6.34% [95% uncertainty interval ( UI): 6.23%-6.44%], lower than the global average level (11.24%,95% UI: 11.16%-11.32%) or the average level of low-income (13.15%, 95% UI: 12.97%-13.33%), lower-middle income (12.53%, 95% UI: 12.39%-12.68%), upper-middle income (8.22%, 95% UI: 8.15%-8.29%) and high-income (8.75%, 95% UI: 8.67%-8.84%) countries. The DALYs rate (person-year /100 000) of preterm birth in China was 217.12 (95% UI: 191.30-246.69), lower than the average level of the world (886.81, 95% UI: 762.12-1 034.49), low-income (1 905.24, 95% UI: 1 542.35-2 377.54), lower-middle-income (1 349.98, 95% UI: 1 154.04-1 583.81) and upper-middle-income (366.56, 95% UI: 321.51-416.88) countries, but higher than the average level of high-income countries (206.21,95% UI: 179.96-234.90). From 1990 to 2019, the prevalence and DALYs rate of preterm birth in China showed a downward trend, with an average annual decline of 0.56% (95% CI:0.54%-0.58%) and 5.87% (95% CI:5.54%-6.19%), respectively. In general, the prevalence rate of preterm birth in men declined faster than that in women (men:0.64%, 95% CI: 0.62%-0.66%; women: 0.46%, 95% CI: 0.44%-0.48%), so as the DALYs rate (men:5.90%, 95% CI: 5.56%-6.24%; women:5.81%,95% CI: 5.50%-6.13%). Conclusions:From 1990 to 2019, the prevalence and DALYs rate of preterm birth in China showed an overall downward trend, and the decline rate was higher in men than in women. The etiological research on the risk factors of preterm birth, especially spontaneous preterm birth, should be further pursued, and a more comprehensive and precise monitoring, prevention, and health care system for preterm birth needs to be formulated.
