Abstract:
Objective:To analyze the burden indicators and trend predictions of eating disorders in Chinese adolescents aged 10-24 years from 1990 to 2019, so as to provide a reference for the prevention and control of eating disorders among adolescents.
Methods:According to the latest data of the Global Burden of Disease Study(GBD) 2019 database classified by gender, age group and other indicators, the Joinpoint regression model and bayesian age period cohort model(BAPC) were used to analyze and predict the incidence rate, prevalence and disabilityadjusted life year (DALY) rate of eating disorders among Chinese adolescents aged 10 to 24 years old, and explore the trend of the disease burden of eating disorders in this population in the past three decades.
Results:From 1990 to 2019, the overall crude incidence rate of eating disorders among adolescents in China increased from 278.93/105 to 422.27/105, and the crude incidence rate increased from 122.63/105 to 198.80/105, and the crude DALY rate increased from 26.67/105 to 43.50/105. In terms of gender, the standardized incidence rate, standardized prevalence rate and standardized DALY rate of eating disorders of boys and girls all showed an upward trend（boys：AAPC=1.52%，1.84%，1.86%，girls：AAPC=1.28%，1.74%，1.77%，P＜0.05）. The standardized incidence rate, standardized prevalence rate and standardized DALY rate of boys with eating disorders (54.97%, 68.88%, 69.75%) were higher than those of girls (44.26%, 64.48%, 65.56%), and the differences were statistically significant (χ2=201.45, 35.02, 34.55, P<0.05). In terms of age groups, the incidence rate of the 15-19yearold age group (524.10/105) was higher than that of other age groups (10-14yearold age:251.17/105, 20-24yearold age:476.49/105) (χ2=156.87, P<0.05), the prevalence rate of the 20-24yearold age group (278.67/105) and the DALY rate (60.83/105) were higher than those of other age groups (10-14yearold age:81.79/105,18.02/105, 15-19yearold age:221.81/105,48.59/105) (χ2=204.50,197.14, P<0.05). BAPC prediction model showed that in the future, the incidence rate of eating disorders among adolescents in China would still show an upward trend, but the prevalence rate and DALY rate would show a steady downward trend, which might reach 516.43/105, 188.41/105 and 41.23/105 respectively in 2030.
Conclusions:The burden of eating disorders among adolescents in China continues to increase, with boys and those aged 15-19 years being the key populations for prevention and treatment. All sectors of society should actively take relevant measures and pay attention to the prevention and treatment of adolescent eating disorders.
