Background: Micronutrient deficiency has long been recognized as a public health problem, particularly among vulnerable groups such as children, adolescents, pregnant and lactating women. Micronutrient deficiency could not be ruled out in spite of the implementation of various intervention strategies. Different interventions are being used to prevent and treat micronutrient deficiencies at the national and global level. The aim of this study is to systematically review the intervention strategies among different vulnerable age groups in India.

Methods: The review was focused on identifying various interventions published based on the internet databases and the peer-reviewed papers from 2011 to 2021, on the predefined inclusive/exclusive criteria. The major intervention strategies implemented in India were recognized and evaluated based on dietary supplementation, micronutrient supplementation, knowledge interventions and food fortification among various age groups.

Results: The results show that there are still considerable gaps in identifying the effective intervention strategies, research initiatives, programs and policies addressing to tackle micronutrient deficiencies in India. Multiple interventions are effective that could lead the road to innovations in approaches with diverse dietary intake, developing multiple micronutrient supplements, fortifying foods and nutrition interventions to address calcium, zinc, iodine, vitamin D and vitamin A deficiencies among the vulnerable population.

Conclusion: Evidence-based multiple intervention studies covering a large population, in the long term cross-sectional, is the need for the hour to design policies and programs for improving the micronutrient status of vulnerable population in the community.
