The main objective of the Second National Integrated Micronutrient Survey (NIMS-II) was to assess the nutritional status of four micronutrients, namely iron, zinc, and vitamins A and D, and also to conduct an anthropometric assessment of selected groups of children, adolescents, pregnant women, and adults, disaggregated by sex and residential area in nationally representative samples. This paper reports the design of the study along with preliminary findings.
In this study, 32 770 individuals were selected by using single-stage cluster sampling. Venous blood samples were collected on site for laboratory analysis; interviews were conducted, and anthropometric measurements were performed.
The prevalence of anemia was highest (17.1%) among 15- to 23-month-old children; vitamin A deficiency was 18.3% in this age group. As regards iron deficiency anemia, the prevalence in all age/sex groups was less than 5%, ranging from 0.5% in 6-year-old children to 4.2% in 15- to 23-month-old children. Zinc and vitamin D deficiencies were highest among pregnant women (8% and 85.3%, respectively). Finally, the prevalence of overweight and obesity among adults was 40.3% and 29.2%, respectively.
Results of this study can help in designing nutritional intervention programs for nationwide implementation. Of all micronutrient deficiencies, vitamin D deficiency was the most prevalent in all study groups. Thus, appropriate actions should be taken in our community.
第二次全国综合微量营养素调查（NIMS-II）的主要目的是评估四种微量营养素（铁、锌和维生素 A 和 D）的营养状况，并对选定的儿童、青少年、孕妇和成年人组进行人体测量评估，按性别和居住区域在全国代表性样本中进行细分。本文报告了该研究的设计以及初步结果。
本研究采用单阶段聚类抽样法选择了 32770 人。现场采集静脉血样进行实验室分析；进行访谈和人体测量。
15-23 个月大的儿童贫血患病率最高（17.1%）；该年龄段维生素 A 缺乏率为 18.3%。至于缺铁性贫血，所有年龄/性别组的患病率均低于 5%，从 6 岁儿童的 0.5%到 15-23 个月儿童的 4.2%。孕妇缺锌和维生素 D 缺乏的比例最高（分别为 8%和 85.3%）。最后，成年人超重和肥胖的患病率分别为 40.3%和 29.2%。
本研究结果可有助于为全国实施设计营养干预计划。在所有微量营养素缺乏中，维生素 D 缺乏在所有研究组中最为普遍。因此，我们的社区应采取适当的行动。
