Zero Hidden Hunger EU - Reducing Micronutrient Deficiencies

Aims

To quantify the prevalence of and risk factors for Hidden Hunger defined as two or more specific micronutrient (vitamins and minerals) deficiencies in the English primary care patients and to use this to inform a European Hidden Hunger prevalence as well as to elucidate country specific issues.

Deliverables

A report to the EU funders and a scientific manuscript

Expected Impact

Our study using a large database of primary care data will yield precise estimates of the prevalence of micronutrient deficiencies to inform the extent of Hidden Hunger in the UK among different population sub-groups, including high-risk subgroups such as children and women of child bearing age, and how it compares to other European countries. Our work will also identify risk factors that need to be addressed to prevent these deficiencies. 

Project outline

Beyond visible famine, "hidden hunger" affects millions across all social classes through subtle but harmful deficiencies in essential vitamins and minerals. Although these deficiencies often lack obvious symptoms, they can significantly impair long-term health, productivity, and quality of life. Vulnerable groups, including children, pregnant women, older adults, and ethnic minorities, are particularly at risk for these deficiencies.

How does this research try to address the problem?

Using the Oxford-Royal College of General Practitioners Clinical Informatics Digital Hub (ORCHID) database, we will perform a retrospective cohort study between 2015 and 2025 to measure the prevalence of deficiencies in relevant micronutrients (vitamins and minerals) measured in blood and urine among relevant subgroups of the population including children, pregnant women, ethnic minorities, and older adults.

How we are planning to implement the research outputs 

The findings from this study will identify the prevalence of Hidden Hunger in the UK and will inform Europe-wide modelling of estimates.  Identifying risk factors for Hidden Hunger will also help inform the appropriate strategies to tackle this nationally and internationally.

How were the patient and public involved? 

The parent EU project will disseminate their findings to relevant stakeholder groups, including patients and service users and those living with hidden hunger, and these groups will also be involved in the development of strategies to tackle hidden hunger, as informed by the study findings.
