Bridging the vitamin A and deworming coverage gap among underserved populations in India through government and civil society organization partnerships.

BACKGROUND

Vitamin A deficiency (VAD) is a major public health problem in India, where approximately 62% of children under five have low retinol levels (< 70 µmol/L). This study aims to (1) evaluate vitamin A supplementation (VAS) and deworming (VAS + D) coverage in Nagaland state through government and civil society organization (CSO) partnerships, (2) examine socio-demographic barriers and facilitators to VAS + D coverage, (3) examine associations between socio-demographic characteristics and source of VAS coverage (i.e., government vs. CSOs), and (4) estimate the impact of VAS on health outcomes due to increased coverage through government and CSO partnerships.

METHODS

A cross-sectional statewide coverage survey was conducted in Nagaland, India with 1,272 caregivers of children 6-59 months. Household socio-demographic data and VAS + D exposure variables were collected via quantitative survey. Univariate analyses were used to assess the associations between the independent and outcome variables; odds ratios were computed to measure the strength of the association at a significance level of < 0.05. The Lives Saved Tool (LiST) was used to estimate the impact of increased VAS coverage on child undernutrition, morbidity and mortality.

RESULTS

Most children (77.2%) received VAS in the past six months, with 28.1% receiving VAS in capsule form (provided primarily by CSOs) and 70.2% received VAS in syrup form (provided primarily by government). Total deworming coverage was 74.2%, with 43.5% receiving both VAS and deworming. Lower pre-school enrollment was a barrier to receiving VAS (47.4% not enrolled vs. 80.9% enrolled, p < 0.001). A barrier to receiving VAS + D was lack of knowledge of benefits (p < 0.001). Based on LiST modeling, increasing VAS coverage by 22% through CSOs resulted in an estimated 114 stunting cases averted, 25,017 diarrhea cases averted, and 9 lives saved in 2019 in Nagaland State.

CONCLUSIONS

Government and CSO partnerships can reduce disparities in VAS coverage and decrease under-five child morbidity and mortality.
