According to Gram Research analysis, nearly 1 in 4 older adults with chronic wounds (24.4%) have malnutrition, with nearly 7 in 10 not eating enough protein needed for healing. A prospective cohort study of 78 patients over age 65 found that loss of appetite, eating alone, and digestive problems are major barriers preventing adequate nutrition in this vulnerable population.
A new study found that nearly 1 in 4 older adults with chronic wounds aren’t getting enough nutrition to help their bodies heal. Researchers in Canada followed 78 people over age 65 with long-lasting wounds and discovered that poor nutrition is a major problem in this group. The study identified common reasons why these patients struggle to eat well, including loss of appetite, eating alone, and digestive issues. The findings suggest that doctors should routinely check nutrition status in older patients with wounds, since proper nutrition is essential for healing.
Key Statistics
A 2026 prospective cohort study of 78 older adults with chronic wounds found that 24.4% had a clinical diagnosis of malnutrition, with 69.2% experiencing inadequate protein intake critical for wound healing.
According to research reviewed by Gram, older adults with chronic wounds who had psychiatric diagnoses were 76 times more likely to be malnourished compared to those without psychiatric conditions.
A 2026 study of 78 patients aged 65+ with chronic wounds identified that loss of appetite (46.2%), eating meals alone (30.2%), and constipation (19.2%) were the most common barriers to adequate nutrition.
Research shows that for every additional year of age, older adults with chronic wounds had 20% higher odds of malnutrition, while being male was associated with significantly lower malnutrition risk.
The Quick Take
- What they studied: How many older adults with chronic wounds (long-lasting sores that won’t heal) have malnutrition, and what prevents them from eating well
- Who participated: 78 people aged 65 and older with chronic wounds who visited a wound clinic in Calgary, Canada between April 2022 and March 2023. Average age was about 76 years old.
- Key finding: Nearly 1 in 4 older adults with chronic wounds (24.4%) were clinically diagnosed with malnutrition. Even more concerning, about 7 in 10 weren’t eating enough protein, which is critical for wound healing.
- What it means for you: If you’re an older adult with a chronic wound, getting proper nutrition screening from your doctor is important. Common eating problems like loss of appetite or eating alone can be addressed with help from healthcare providers and nutritionists.
The Research Details
This was a prospective cohort study, which means researchers followed a group of people over time and collected information about their nutrition status. The study took place at a specialized wound clinic in Calgary, Canada, over one year (April 2022 to March 2023). Researchers recruited 78 older adults with chronic wounds and assessed their nutrition using clinical evaluations. They collected information about each person’s age, gender, medical conditions, and barriers to eating well.
The researchers looked at whether patients had malnutrition (the main outcome) and also examined other nutrition-related problems like inadequate protein intake and lack of nutrition knowledge. They asked patients about specific challenges they faced with eating, such as appetite loss, eating alone, and digestive problems. The study also examined how factors like age, gender, and certain medical conditions affected malnutrition risk.
This research approach is important because it captures real-world information from actual patients in a clinical setting rather than a laboratory. By following patients over time, researchers could identify patterns and risk factors for malnutrition in older adults with wounds. Understanding these barriers helps doctors and nutritionists develop better strategies to support healing in this vulnerable population.
This study has several strengths: it was conducted in a real clinical setting with actual patients, used standardized nutrition assessments, and examined multiple factors affecting malnutrition. However, the sample size of 78 patients is relatively small, and the study was conducted at a single clinic in Canada, so results may not apply to all older adults everywhere. The study was published in a peer-reviewed journal, which means other experts reviewed the methods and findings.
What the Results Show
The study found that 24.4% of older adults with chronic wounds had a clinical diagnosis of malnutrition. This is notably higher than the estimated 34.2% of community-dwelling older adults in Canada who are at risk of malnutrition, suggesting that having a chronic wound may increase actual malnutrition rates.
The most common nutrition problems were inadequate protein intake (affecting 69.2% of participants) and lack of knowledge about proper nutrition (67.9%). These findings are particularly important because protein is essential for wound healing—without enough protein, the body struggles to repair damaged skin and tissue.
The study identified several barriers preventing older adults from eating well. Loss of appetite was the most common problem, affecting 46.2% of participants. Eating meals alone was reported by 30.2%, and constipation (a digestive problem) affected 19.2%. These barriers suggest that malnutrition in this group isn’t always about food availability but rather about appetite, social factors, and physical health challenges.
The research revealed important patterns about who is at highest risk. Older age itself increased malnutrition risk—for every year older, the odds of malnutrition increased by 20%. Interestingly, being male was protective, with men having much lower odds of malnutrition compared to women. Patients with psychiatric conditions (like depression or anxiety) had dramatically higher odds of malnutrition—76 times higher than those without psychiatric diagnoses. Patients with hypothyroidism (an underactive thyroid) also had significantly higher malnutrition risk, about 20 times higher than those without this condition.
Previous research estimated that about 34.2% of older adults living in the community in Canada were at risk of malnutrition. This new study found that 24.4% of older adults with chronic wounds had clinically diagnosed malnutrition. While this appears lower, it’s important to note that the previous estimate was about ‘risk’ while this study measured actual diagnosed malnutrition. The findings suggest that chronic wounds may be a marker for identifying older adults who need nutrition screening, even if not all of them meet the threshold for malnutrition diagnosis.
The study included only 78 patients from a single wound clinic in Canada, so the results may not apply to older adults with wounds in other regions or countries with different healthcare systems. The study was conducted over one year, so it doesn’t show long-term outcomes or whether nutrition interventions improved wound healing. The research didn’t include a comparison group of older adults without wounds, making it harder to determine if malnutrition is specifically caused by having a chronic wound or if it’s a broader issue in this age group. Additionally, the study relied on information patients reported about their eating habits, which may not always be completely accurate.
The Bottom Line
Healthcare providers should routinely screen older adults with chronic wounds for malnutrition as part of standard care (strong evidence). Patients should be assessed for protein intake and barriers to eating, such as appetite loss and social isolation (strong evidence). Nutrition interventions addressing identified barriers—like appetite stimulation, social eating opportunities, and management of digestive problems—should be considered (moderate evidence based on this study’s findings).
This research is most relevant to older adults (65+) with chronic wounds, their family members, and healthcare providers including doctors, nurses, and nutritionists who care for this population. It’s particularly important for people with psychiatric conditions or thyroid problems, who showed the highest malnutrition risk. Community health workers and social services professionals should also be aware, as eating alone and social isolation were identified barriers.
Nutrition improvements may support better wound healing within weeks to months, but chronic wounds typically take much longer to heal (often 3-12 months or more). Addressing malnutrition should be viewed as a long-term commitment to supporting overall health and healing capacity.
Frequently Asked Questions
Why do older adults with wounds struggle to eat enough?
Common reasons include loss of appetite (affecting 46% of older adults with wounds), eating meals alone (30%), and digestive problems like constipation (19%). Mental health conditions and thyroid problems also significantly increase malnutrition risk in this group.
How much protein do older adults with chronic wounds need?
While this study didn’t specify exact amounts, it found that 69% of older adults with wounds weren’t eating enough protein. Your doctor or nutritionist can recommend a specific protein goal based on your age, weight, and wound severity.
Can malnutrition slow down wound healing?
Yes. Protein and other nutrients are essential for your body to repair damaged skin and tissue. The study found that nearly 1 in 4 older adults with chronic wounds had malnutrition, suggesting nutrition screening should be routine care for wound patients.
Should doctors automatically check nutrition in older patients with wounds?
The study strongly suggests yes. Researchers found that malnutrition is common in older adults with chronic wounds and recommend nutrition assessments become standard care in wound clinics, especially for patients over 75 or with psychiatric conditions.
What can help if I’m losing my appetite while healing a wound?
Talk to your doctor or nutritionist about appetite loss, which affected nearly half the study participants. Solutions may include eating with others (the study found eating alone was a barrier), trying different foods, eating smaller frequent meals, or addressing underlying conditions like depression or thyroid problems.
