Under nutrition in later life is everyone’s business.

It’s important that all Health Care Professionals can recognise the signs of unintended weight loss and know what to do if someone is at risk, wherever they work, in the community a care home, older peoples own home and hospitals.

The Malnutrition Task Force’s report, The State of the Nation: Older People and Malnutrition in the UK Today, provides an overview of the scale of the challenge and how well it’s currently being addressed across sectors and settings. (This publication will be regularly updated so will also contain the latest stats for your information.) 

Please join BAPEN in undertaking the next national survey of malnutrition and nutritional care during Malnutrition Awareness Week (MAW2019).

We are asking for your help to get as many individuals working in health and social care settings to screen for malnutrition using ‘MUST’ and to record any nutritional care a person is given during MAW2019.

Understanding issues

It is estimated that around one in ten people over the age of 65 are malnourished or at risk of malnutrition. That’s over one million older people in the UK today.

Malnutrition (under nutrition) is characterised by low body weight or weight loss, meaning simply that some older people are not eating well enough to maintain their health and wellbeing. Seemingly overweight people can also feel the physiological effects of unintentional weight loss. 

Weight loss is often unintentional and goes unrecognised until malnutrition starts to seriously undermine someone’s health and wellbeing.

Under nutrition will affect health and wellbeing, increasing hospital admissions, and can lead to long-term health conditions for otherwise healthy and independent older people.

Why is this happening?

Awareness of under nutrition and risk factors amongst older people, their families and many health and care professionals remains low. There is also patchy availability of care and support services to prevent malnutrition, or identify and treat it when it does occur.

The myth perpetuates that it is ‘normal’ to get thin as you get older. This is not helped by health messages and public health policy that are preoccupied by reducing levels of obesity, so that weight loss is often seen as desirable. There is little recognition that widely publicised advice about diet and nutrition is often unsuitable for older or more vulnerable members of society. Yet malnutrition is largely preventable and treatable.

Risk factors

The reasons why an older person might become malnourished are varied. Often there are multiple causes. The causes and consequences of malnutrition are often interlinked and, in some cases, can develop into a vicious cycle.

The reasons why a person becomes malnourished can be split into three main categories:

1. Medical risks

Malnutrition can be a consequence of a particular disease (for example cancer or chronic liver disease), or a side effect of a condition or medication, and can be prevented or treated with proper care and support. Those at risk include people with dementia, cancer, COPD, dysphagia or older people at risk of poly pharmacy, which can lead to a reduction in appetite or alter the taste of food.

2. Physical risks

Physical or disability-related risk factors can occur for many reasons and may be related to underlying health problems or a more specific physical difficulty. This can include arthritis, sight loss or limited mobility. Dentition is also a major factor linked to malnutrition in older people as pain, loose teeth or denture problems can prevent people eating well. Read more about oral health.

3. Social risks

Social risk factors that link to unintentional weight loss are often the most complex and range from practical constraints to people’s interest in food and motivation to eat well. These include bereavement, social isolation and loneliness, living on a low income, having a caring responsibility and understanding or attitudes around weight loss and nutrition.
