BACKGROUND/AIMS: Micronutrient deficiencies continue to be a major public health problem in India. The aim of this study was to assess the prevalence and determinants of micronutrient deficiencies among rural children.
A community-based cross-sectional study was carried out by adopting a multistage stratified random sampling procedure. A total of 71,591 preschool children were included for ocular signs, 3,291 preschool children and 6,616 adolescents for hemoglobin, and 28,437 school-age children for iodine deficiency disorders.
The prevalence of Bitot's spots was 0.8% (CI = 0.6-0.9) and anemia among preschool children and adolescents was 67% (CI = 64.4-69.5) and 69% (CI = 67.0-71.4), respectively. The prevalence of total goiter was 3.9% (CI = 3.4-4.6). The risk of Bitot's spots was 2.4 times higher among preschool children of Scheduled Caste (SC) or Scheduled Tribes (ST) than others and risk of anemia was twice as high (CI = 1.5-2.6) among adolescents of SC and ST. The micronutrient deficiencies were significantly lower in children who used sanitary latrines.
Micronutrient malnutrition is a public health problem among rural children, and it was higher among children of SC/ST, illiterate parents and those not possessing a sanitary latrine. Thus, there is a need to improve environmental sanitation; fortification of foods could also help in mitigating the problem.
背景/目的:微量营养素缺乏仍然是印度的一个主要公共卫生问题。本研究旨在评估农村儿童微量营养素缺乏的流行情况及其决定因素。
采用多阶段分层随机抽样程序进行基于社区的横断面研究。共纳入 71591 名学龄前儿童进行眼部体征检查,3291 名学龄前儿童和 6616 名青少年进行血红蛋白检查,28437 名学龄儿童进行碘缺乏症检查。
Bitot 斑的患病率为 0.8%(CI = 0.6-0.9),学龄前儿童和青少年贫血的患病率分别为 67%(CI = 64.4-69.5)和 69%(CI = 67.0-71.4)。总甲状腺肿的患病率为 3.9%(CI = 3.4-4.6)。与其他儿童相比,表列种姓(SC)或表列部落(ST)的学龄前儿童发生 Bitot 斑的风险高 2.4 倍,而 SC 和 ST 的青少年贫血的风险高 2 倍(CI = 1.5-2.6)。使用卫生厕所的儿童微量营养素缺乏症明显较低。
微量营养素营养不良是农村儿童的一个公共卫生问题,SC/ST 儿童、文盲父母和没有卫生厕所的儿童中情况更为严重。因此,需要改善环境卫生;食物强化也有助于缓解这一问题。
