WOFAN Supports Invention of Nutrition and Growth Monitoring Wheel – A Hands-on Tool for Screening Malnutrition

A team of medical and biotechnology innovators, working with WOFAN as entrepreneur  volunteers  on nutrition activities, has invented a Growth Screening Wheel to screen children (especially children under 5 years) for malnutrition.

The innovation is a hands-on tool for screening and monitoring malnutrition at all levels.

After identifying gaps in the measurement of the impact of nutrition intervention programs on children under 5 years, WOFAN commissioned its Health and Nutrition Team led by Dr. Nathaniel George to explore ways of closing the identified gaps ranging from how malnourished children are indentified to how their recovery is measured.  

And, based on field experiences, the team came up with the Growth Screening Wheel, a simple and innovative tool designed to conveniently present the standard z-scores of the weight-for-age, height-for-age, weight-for-height and other growth indices in a fun and easy to use format.      

The Wheel is a quick and convenient way of screening under 5 children based on the SD0, SDneg3 and SD3 standards. It also keys quite well into SDG 2.2 which aims at ending all forms of malnutrition by 2030, including achieving by 2025 the internationally agreed targets on stunting and wasting in children under 5 years of age while also addressing the nutritional needs of adolescent girls, pregnant and lactating women as well as older persons.

The Growth Screening Wheel is not a replacement for the commonly used devices. It however makes the use of the devices more meaningful for community or development intervention as it makes data collection and interpretation on the field less cumbersome and more meaningful. 



For instance, while the commonly used equipment such as the weighing scale, stadiometer, infantometer, etc show the present state of the child, the Growth Screening Wheel gives a clear and instant mental picture of where that particular child is among the general population of his/her age group and where the child should be.

Also, while the use of the weight-for-age, height-for-age and weight-for-height tables and charts on the field may be cumbersome, clumsy, time consuming and require trained personnel to use, the Growth Screening Wheel is portable, requires very minimal training and can be easily understood and used by mothers and ad hoc health and nutrition volunteers right there on the field thereby enhancing the sustainability of monitoring and evaluation for nutrition intervention programs.

And, the Growth screening Wheel presents the SD3neg, SD0 and SD3 figures and so it can be used to conveniently screen out the outliers (SD3neg and SD3) who will require urgent attention among a given population such as in the internally displaced persons (IDPs) camps in the North East.

The innovation will find a lot of useful applications in assessing progress or success of nutrition intervention strategies for target population of under-5 children such as school feeding programs or community interventions.


The Growth Screening Wheel has been presented and demonstrated at several forums, including at UNIDO Office in Lagos and e-Health Africa’s Kano office.

We are equally pleased to introduce the Jugular Venous Pressure (JVP) scale a handy instrument developed for the accurate measurement of jugular venous pressure.
