Abstract：
UNASSIGNED: Vitamin A deficiency (VAD) is a common micronutrient deficiency that imposes a substantial burden worldwide. This study examined the burden of VAD from 1990 to 2019 in the Middle East and North Africa (MENA) region by age, sex and sociodemographic index (SDI).
UNASSIGNED: The data were obtained from the Global Burden of Disease (GBD) 2019 database. We reported the prevalence, incidence, and years lived with disability (YLDs) that were attributable to VAD for the MENA region, along with its constituent countries.
UNASSIGNED: In 2019, the MENA region had 30.6 million prevalent cases of VAD, with an age-standardized prevalence rate of 5249.9 per 100,000 population. In addition, VAD was responsible for 62.2 thousand YLDs, with an age-standardized YLD rate of 10.2 per 100,000. The age-standardized prevalence [50.3% (-55.9 to -44.7)] and YLD [-49.3% (-55.3 to -43.1)] rates of VAD have significantly decreased since 1990. In 2019, the MENA region\'s VAD-attributable YLD rate was below the global average for males and females across all age groups. Additionally, SDI was negatively associated the age-standardized YLD rate of VAD.
UNASSIGNED: This study underscores the necessity of frequently updating health data and developing guidelines and regulations to prevent, detect early, and effectively treat VAD in the MENA countries.

摘要：
■维生素A缺乏症（VAD）是一种常见的微量营养素缺乏症，在全球范围内造成沉重负担。这项研究按年龄调查了中东和北非（MENA）地区1990年至2019年的VAD负担，性别和社会人口指数(SDI)。
■数据来自全球疾病负担（GBD）2019数据库。我们报告了患病率，发病率,以及MENA地区归因于VAD的残疾年份（YLDs），及其组成国家。
■2019年，MENA地区有3060万例VAD，年龄标准化患病率为每100,000人口5249.9。此外,VAD负责62.2万YLD，年龄标准化YLD率为10.2/100,000。自1990年以来，VAD的年龄标准化患病率[50.3％（-55.9至-44.7）]和YLD[-49.3％（-55.3至-43.1）]率显着下降。2019年，MENA地区的VAD归因YLD率低于所有年龄组男性和女性的全球平均水平。此外,SDI与VAD的年龄标准化YLD率呈负相关。
■这项研究强调了经常更新健康数据并制定指导方针和法规以预防健康数据的必要性，及早发现,并有效治疗MENA国家的VAD。
