Professor Margaret Armar-Klemesu is an Associate Professor in the Department of Nutrition, NMIMR. Professor Armar-Klemesu joined NMIMR in 1980 as a Senior Research Assistant. From 1984 to 1989 she undertook graduate studies in Nutrition at the London School of Hygiene and Tropical Medicine (University of London) under WHO and UNU fellowships, graduating with an MSc in Human Nutrition (Public Health option) and a PhD in Applied Human Nutrition.

 In 1989 Prof. Armar-Klemesu returned to NMIMR as a Research Fellow in the Nutrition Department, finally gaining appointment on promotion as Associate Professor in 2008.  In addition to her research work she taught courses and/or supervised graduate students at the School of Allied Health Sciences, School of Public Health and the Department of Nutrition and Food Science.  She has also supervised graduate students from the University for Development Studies (Tamale) and Wageningen University (Netherlands). She was head of the Nutrition Department for two periods and further served two consecutive terms as Acting Deputy Director of the Institute.


Prof. Armar-Klemesu has made significant contributions to the field of nutrition and health locally and internationally and has an enviable track record of research collaborations and consultancies.Among them are the collaboration with the Tokushima University (Japan), International Food Policy Research Institute (IFPRI, Washington DC, USA) and WHO, Initiative for Maternal Mortality Programme Assessment (University of Aberdeen, Scotland), Population Council and Ghana Health Service and Wagningen University. She was a consultant for Freedom from Hunger (USA), Unilever (Ghana), Linkages Project (Academy for Educational Development, USA), UNICEF, and more recently the Global Alliance for Improved Nutrition (GAIN) with support from USAID.


Prof. Armar-Klemesu’s most notable work include the following:

  • ·         1995 – 1998: Co-Principal Investigator for the Accra Urban livelihoods, food and nutrition security study as part of IFPRI’s multi-country research programme on Urban challenges to food and nutrition security.
  • ·         1996 – 2005:  Consultant/resource person for various organizations implementing Behaviour Change Communication and other intervention programmes to improve the nutrition of infants and young children, mainly leading formative and impact evaluation research activities.
  • 2002 – 2007: Country Technical Partner Leader for the Initiative for Maternal Mortality Programme Assessment (IMMPACT), a global research initiative to improve the evidence base for decision making for safe motherhood interventions. IMMPACT evaluated Ghana’s free delivery care policy.
  • 2004 – 2006: Principal Investigator for the NMIMR/Population Council (Frontiers in Reproductive Health Programme)/Ghana Health Service collaborative research to assess the acceptability, feasibility and affordability of the WHO Focused Antenatal Care package in Ghana.
  • ·         2009 to present: Consultant for GAIN, specifically contributing to the development and application of the Focused Ethnographic Study (FES) tool. The FES is a formative research tool purposely developed to aid evidence-based decision making for nutrition programmes by identifying context-specific (i.e social, economic and cultural) interventions to improve infant and young child nutrition (IYCN) in resource-poor settings.

Prof Armar-Klemesu has since contributed to the application of the FES tool to IYCN research in Kenya, South Africa, Afghanistan and Ghana and also trained staff from development organisations implementing child health and nutrition interventions. A modified version of the FES has also been developed and used to study food consumption patterns in women of reproductive age in Ghana.


Administrative Role

Member, College of Health Sciences and University of Ghana Academic Boards


Completed research projects

  • ·         A focused ethnographic study of food consumption patterns and their social and cultural context in pregnant, lactating women and in adolescents to inform future interventions to improve nutrition in women of reproductive age. This study was one of formative research activities carried out for the Affordable Nutritious Foods for Women (ANF4W) Project. ANF4W is a multi-stakeholder public-private partnership initiative to promote availability and accessibility of fortified local food products targeted at women of reproductive age.(Funded: DSM Sight and Life, 2014; Principal Investigator)
  • ·         A Focused ethnographic study and quantitative food consumption survey of infants and young children in rural northern and southern Ghana. This was a USAID/GAIN supported project in collaboration with the University for Development Studies (Tamale) and Wageningen University to identify evidence-based, population-specific food-based recommendations to improve the micronutrient and overall nutrition status of infants and young children in rural farming communities. (Funded: USAID/GAIN, 2014 to 2015, Principal Investigator)


On-going projects

  • ·         Affordable Nutritious Foods for Women (ANF4W) Project: Fortified food products availability and consumption by women of reproductive age in Ghana. This phase of the project is aimed at test-marketing 4 fortified food product prototypes (biscuits, soy drink, instant porridge and pepper sauce (“shito”) in the Northern and BrongAhafo regions (Funded Deutsche Gesellschaft für Internationale Zusammenarbeit  (GIZ), 2016 to 2017; Principal Investigator)
