Core Project in Nigeria

CROWN Core Projects are independent research projects engaged in the collaborative. Each Core Project focuses on increasing adherence to maternal micronutrient supplements among women of reproductive age. As members of the collaborative, Core Projects collaborate with each other by sharing knowledge, resources, and findings across the project lifespan.

Women's health

  • Maternal mortality ratio (per 100,000 live births): 917 deaths1
  • Anemia prevalence (women of reproductive age): 55%1
  • Anemia prevalence (pregnant women): 56%1
  • Anemia prevalence (non-pregnant women): 55%1
  • 4+ ANC visits during pregnancy: 57%2
  • Receipt of iron tablets or syrup (among those with 4+ ANC visits): 69%3

Child health

  • Under-five mortality rate (per 1,000 live births): 114 deaths2
  • Child stunting (<2SD from the median height-for-age): 35%2
  • Child wasting (<2SD from the median weight-for-height): 7%2


The project is being led by Nutrition International. Nutrition International (NI), formerly the Micronutrient Initiative, is a global leader in nutrition. For 30 years, NI has worked with a wide range of donors, governments, UN agencies, civil society, research institutions and other partners across the world to promote, accelerate and facilitate the scale-up of high-impact nutrition interventions within health, food, and education systems. NI works as an ally to the government to implement nutrition interventions and solutions to malnutrition – including micronutrient deficiencies – through different programs. NI also conducts high quality implementation research, incorporating the skill sets of a diverse and dynamic group of technical experts in public health, nutrition, and research.

Country Indicators

Anaemia remains a severe public health problem (4) in Nigeria affecting 58% of WRA and 86% of pregnant women nationally in 2021. Anemia prevalence was higher in Northern states as it affected 74% of WRA in 2021, with Bauchi state having the highest statistic of 68.6% (5). Maternal anaemia puts the mother at increased risk of death and increases the risk of poor pregnancy and birth outcomes (6). Potential poor pregnancy outcomes include increased risk of low birth weight and preterm birth, which can lead to poor growth trajectories later in childhood and beyond (6).  Reporting on birth weight remains poor in Nigeria and the prevalence of low birth weight is expected to be largely underreported, but the NDHS-2018 estimates seven percent of all births nationally weighing less than 2500 g, with this figure estimated to rise as high as 34% in some Northern states. In Bauchi state, according to NDHS-2018, the prevalence of low-birth weight among newborns in Bauchi State was 12.1%.
