The objective of this study was to identify trends and change in micronutrient supplementation (MNS) knowledge across pregnancy and post-partum and to assess the impact of MNS knowledge (MNS-k) on practice in pregnancy in rural Tibet, an area with endemic micronutrient deficiency. A prospective cohort with repeated measures at early, late and after pregnancy in a rural area in the Tibetan Autonomous Region included women receiving care by community workers. Key messages about MNS-k and optimal MNS practice were communicated through health worker encounters with pregnant women. Outcomes included MNS consumption practice, knowledge and attitudes. The proportion of women in the highest MNS-k category increased by 35% from early to late pregnancy (37.5–50.7%, respectively;p< .005). MNS-k was associated with MNS consumption in a dose–response manner over pregnancy (trendX2p-value < .0001), with increasing knowledge associated with increased MNS consumption. By late pregnancy, 32.5% of women had never consumed an MNS in this pregnancy, and 51.5% had not consumed an MNS on the assessed day or the day before. Sustained knowledge of MNS improved in pregnancy and post-partum. Best practice around MNS consumption increased though remained sub-optimal. [ABSTRACT FROM AUTHOR]
