Iodine deficiency disorders are a public health problem in India. The aim of the study was to examine the effect of multi-micronutrient-fortified biscuits on urinary iodine levels of adolescent girls (n = 51, 10-16 years) studying in a government school in Jaipur city, India.
The study was designed as an intervention study. Biscuits fortified with 150 mcg iodine, 30 mg iron, 100 mcg folic acid, 600 mcg vitamin A and 40 mg vitamin C were provided daily to the subjects on all working days over a 4-month period. The iodine status of the adolescent girls was determined through urinary iodine levels.
Supplementation with biscuits resulted in a significant increase in the mean urinary iodine level from 118.2 to 157.2 mcg/l and in the median value from 121 to 149 mcg/l. Prior to the intervention, 21.6% of the subjects had mild iodine deficiency but at the end of the intervention period, all the girls were iodine sufficient. Hence, iodine supplementation using biscuits resulted in improved iodine status of Indian adolescent girls.
It is, therefore, recommended that the school system be used for micronutrient supplementation interventions to improve the nutritional status of children and adolescents as there is more regimentation in a school setting for distribution of nutrient fortified food products to students.
碘缺乏症是印度的一个公共卫生问题。本研究的目的是检验多种微量营养素强化饼干对就读于印度斋浦尔市一所政府学校的青春期女孩（n = 51，年龄10 - 16岁）尿碘水平的影响。
本研究设计为一项干预性研究。在4个月的所有工作日，每天为受试者提供添加了150微克碘、30毫克铁、100微克叶酸、600微克维生素A和40毫克维生素C的饼干。通过尿碘水平测定青春期女孩的碘状况。
补充饼干后，平均尿碘水平从118.2微克/升显著增加至157.2微克/升，中位数从121微克/升增加至149微克/升。干预前，21.6%的受试者存在轻度碘缺乏，但在干预期结束时，所有女孩碘充足。因此，使用饼干补充碘可改善印度青春期女孩的碘状况。
因此，建议利用学校系统进行微量营养素补充干预，以改善儿童和青少年的营养状况，因为在学校环境中向学生分发营养强化食品更具规范性。
