Purpose of consultancy

To contribute to the measurement and monitoring of nutritional status and nutritional care services among older persons under the WHO TAG4MHA (Technical Advisory Group for Measurement of Healthy Ageing) and WHO TEAM (Technical Expert Advisory Group on nutrition Monitoring).


The Member States have committed to improving the nutritional status of all ages, as evidenced by several declarations and goals — including a set of six global nutrition targets endorsed by the World Health Assembly (WHA) in 2012 and the second Sustainable Development Goal (SDG 2), which aims to end hunger and all forms of malnutrition by 2030. 

More recently, global communities embraced a sweeping 10-years global plan of action to ensure all older people can live long and healthy lives, formally known as the UN Decade of Healthy Ageing (2021–2030).

The UN declarations recognize primary healthcare as the most inclusive, effective and efficient whole-of-society approach to ensuring older people’s physical and mental capacities and well-being. The declaration further highlights the fundamental role of healthy diets and healthy ageing, equitable and sustainable food systems – along with quality education, gender equality and women’s empowerment, access to safe drinking water and sanitation, and social protection mechanisms – in building healthier societies.

WHO HQ provides specialized technical support to Ministries of Health, WHO country and regional offices to accelerate the implementation of evidence-based nutritional care services for older persons to improve national ageing programmes. Specific support is tailored to country needs/situations and requests and in alignment with national and WHO country support plans. Monitoring the nutritional status of the older person and documenting the impact of public health actions on nutrition is critical to demonstrate the progress and the impact by 2030.

To this end, the Department of Maternal, Newborn, Child, Adolescent Health and Ageing and the Department of Nutrition and Food Safety at WHO aims: 

  1. To mainstream the measurement of nutrition care services in older persons within universal health coverage. 
  2. To elevate the epidemiological profile of older persons with nutritional impairments (underweight and overweight).
  3. To advocate for nutrition-inclusive strategies and action plans on healthy ageing.
