Eat Weight Disord. 2025 Apr 26;30(1):37. doi: 10.1007/s40519-025-01746-z.
Eating disorders (EDs) have traditionally been viewed as a Western phenomenon, but their prevalence in South Asia has risen due to urbanization, globalization, and Westernized beauty ideals. This systematic analysis examines trends and prevalence of Anorexia nervosa (AN) and Bulimia nervosa (BN) using the Global Burden of Disease (GBD) data from 1990 to 2021.
This analysis used data from the GBD study on age-standardized prevalence rates (ASPRs) for AN and BN, as well as their total percentage changes (TPCs) from 1990 to 2021. Trends were analyzed using Joinpoint regression to identify changes over time and calculate annual percent changes (APCs) and average annual percent changes (AAPCs). Geospatial patterns and temporal changes were visualized using QGIS software. The correlation between the Sociodemographic Index (SDI) and the DALY rate was assessed using R software.
The ASPR of EDs increased significantly from 1990 to 2021, with BN peaking in the 20-24 age group and AN in the 15-19 and 20-24 age groups. Females exhibited the highest rates of increase, while notable rises were also observed in males. Bhutan recorded the highest ASPR for both AN and BN, with varying temporal percentage changes across countries. A significant positive correlation was found between the SDI and DALY rates across 21 global regions, with anorexia nervosa showing the strongest correlation (r = 0.75, p < 0.001).
The rising burden of EDs in South Asia underscores an urgent need for culturally sensitive prevention strategies and public health policies. Targeted interventions addressing sociocultural drivers are essential to mitigate the growing impact of EDs in this region.

饮食失调传统上被视为西方现象，但由于城市化、全球化和西方化的审美观念，其在南亚的患病率有所上升。本系统分析利用1990年至2021年全球疾病负担（GBD）数据，研究神经性厌食症（AN）和神经性贪食症（BN）的趋势和患病率。
本分析使用了GBD研究中关于AN和BN的年龄标准化患病率（ASPR）数据，以及它们从1990年到2021年的总百分比变化（TPC）。使用Joinpoint回归分析趋势，以确定随时间的变化，并计算年度百分比变化（APC）和平均年度百分比变化（AAPC）。使用QGIS软件可视化地理空间模式和时间变化。使用R软件评估社会人口指数（SDI）与伤残调整生命年（DALY）率之间的相关性。
从1990年到2021年，饮食失调的ASPR显著增加，BN在20 - 24岁年龄组达到峰值，AN在15 - 19岁和20 - 24岁年龄组达到峰值。女性的增长率最高，男性也有显著增长。不丹的AN和BN的ASPR均最高，各国的时间百分比变化各不相同。在21个全球区域中，SDI与DALY率之间存在显著正相关，神经性厌食症的相关性最强（r = 0.75，p < 0.001）。
南亚饮食失调负担的上升凸显了对具有文化敏感性的预防策略和公共卫生政策的迫切需求。针对社会文化驱动因素的有针对性干预对于减轻饮食失调在该地区日益增长的影响至关重要。
