WHAT IS ALREADY KNOWN ABOUT THIS TOPIC?: Previous surveillance data from 2015-2017 showed that Chinese adults aged 18 to 59 years had mean daily vitamin intakes of 406.8 μg retinol equivalent (RE) for vitamin A, 36.7 mg for vitamin E, 0.8 mg for vitamin B, 0.7 mg for vitamin B, 13.9 mg for niacin, and 75.5 mg for vitamin C.
WHAT IS ADDED BY THIS REPORT?: Recent findings from 10 provincial-level administrative divisions (PLADs) reveal that Chinese adults in 2022-2023 had median daily vitamin intakes of 467.8 μg RE for vitamin A, 27.3 mg for vitamin E, 0.7 mg for vitamin B, 0.7 mg for vitamin B, 12.9 mg for niacin, and 51.2 mg for vitamin C. The prevalence of insufficient intake was notably high for vitamins B (84.2%), B (78.0%), C (76.4%), and A (52.6%). Notably, only 1.6% of adults met the proposed intakes preventing non-communicable chronic diseases threshold for vitamin C intake.
WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE?: There is an urgent need for targeted nutrition policies and interventions to address the widespread insufficient intake of vitamins A, B, B, and C among Chinese adults. Increased consumption of fresh vegetables and fruits is particularly recommended to improve vitamin C intake and reduce non-communicable chronic diseases.
关于该主题已知的信息有哪些？：2015 - 2017年的既往监测数据显示，18至59岁的中国成年人维生素A的平均每日摄入量为406.8微克视黄醇当量（RE），维生素E为36.7毫克，维生素B₁为0.8毫克，维生素B₂为0.7毫克，烟酸为13.9毫克，维生素C为75.5毫克。
本报告新增了哪些内容？：来自10个省级行政区的最新研究结果显示，2022 - 2023年中国成年人维生素A的每日摄入量中位数为467.8微克RE，维生素E为27.3毫克，维生素B₁为0.7毫克，维生素B₂为0.7毫克，烟酸为12.9毫克，维生素C为51.2毫克。维生素B₁（84.2%）、B₂（78.0%）、C（76.4%）和A（52.6%）的摄入不足患病率显著较高。值得注意的是，只有1.6%的成年人达到了预防非传染性慢性病的维生素C摄入量建议阈值。
对公共卫生实践有何启示？：迫切需要制定有针对性的营养政策和干预措施，以解决中国成年人中普遍存在的维生素A、B₁、B₂和C摄入不足问题。特别建议增加新鲜蔬菜和水果的摄入量，以提高维生素C的摄入量并减少非传染性慢性病。
