Key Takeaway
Consider routine malnutrition screening in elderly diabetes patients; prevalence is high.

This is a meta-analysis pooling data from 30 studies comprising 12,564 cases of elderly patients with diabetes (age ≥ 60 years). The primary outcome was the prevalence of malnutrition, and secondary outcomes included the prevalence of high malnutrition risk and risk factors for malnutrition. The analysis did not report on study setting, follow-up duration, or comparator groups.

The pooled overall prevalence of malnutrition was 29% (95% CI: 0.19–0.39), based on 21 studies. The prevalence of high malnutrition risk was 42% (95% CI: 0.31–0.53), based on 20 studies. The meta-analysis identified 14 risk factors for malnutrition, but the abstract did not specify what these factors are.

The authors did not report limitations, funding sources, or conflicts of interest. Safety outcomes such as adverse events were not reported. The analysis is observational in nature, so causal inferences should be avoided.

For clinical practice, these findings underscore the high burden of malnutrition and malnutrition risk in elderly patients with diabetes. Routine nutritional assessment may be warranted, and future research should clarify specific risk factors to guide targeted interventions.

A new analysis of 30 studies finds that malnutrition is common among older adults with diabetes. Overall, about 29% of people aged 60 and older with diabetes are malnourished, and 42% are at high risk for malnutrition. These numbers come from a review of 12,564 cases across 30 studies, making it one of the largest looks at this issue.

The analysis also identified 14 risk factors linked to malnutrition, though the specific factors were not listed in the summary. The study did not report any safety concerns, as it was not testing a treatment. Instead, it focused on understanding how widespread malnutrition is in this group.

It's important to note that this is a meta-analysis, which combines results from many studies. While it gives a clearer picture, it cannot prove that any single factor causes malnutrition. Also, the prevalence numbers were based on slightly different sets of studies: 21 studies for the overall rate and 20 for the high-risk rate.

For older adults with diabetes, this highlights the importance of paying attention to nutrition. If you or a loved one has diabetes and are concerned about weight loss or poor appetite, talk to a doctor. They can help assess nutritional status and suggest ways to stay healthy.

What this means for you:
Malnutrition is common in older adults with diabetes; talk to your doctor if you're concerned.

Common questions

How common is malnutrition in elderly diabetes patients?

According to a meta-analysis of 30 studies, about 29% of people aged 60 and older with diabetes are malnourished. Additionally, 42% are at high risk for malnutrition. These numbers come from a review of 12,564 cases.

What are the risk factors for malnutrition in elderly diabetes patients?

The study identified 14 risk factors for malnutrition, but the specific factors were not listed in the summary. To understand your personal risk, it's best to talk with your doctor, who can assess your situation.

Is this study about a new treatment?

No, this is not a treatment study. It is a meta-analysis that combines results from many studies to estimate how common malnutrition is in older adults with diabetes. It does not test any new drug or therapy.

The prevalence and risk factors of malnutrition in elderly patients with diabetes are unclear, a knowledge gap that this meta-analysis aimed to explore. Studies published in the PubMed, Embase, Web of Science, Medline, EBSCO, CNKI, Wanfang, VIP, and Sinomed databases from 1 January 2010, to 31 December 2024 were searched using the following terms with a combination of subject headings and free text: “diabetes,” “malnutrition,” “prevalence,” “risk factors,” “associated factor,” and “influencing factor.” Age filters (age ≥ 60 years) were applied where available. All retrieved studies were manually screened for age criteria. The term “elderly” was not used as a search term to avoid missing studies that enrolled older adults without mentioning “elderly” in the title or abstract. Cohort studies, case–control studies, and cross-sectional studies meeting the inclusion criteria were analyzed. Meta-analysis was performed using Stata 15.0 software. This meta-analysis included 30 studies involving 12,564 cases from 9 countries (namely China, South Korea, Japan, Thailand, Turkey, Nigeria, Spain, Brazil, and India). Based on 21 studies, the overall prevalence rate of malnutrition in elderly patients with diabetes was 29% (95% confidence interval (CI): 0.19–0.39). The analysis of 20 studies revealed that the prevalence rate of high malnutrition risk was 42% (95% CI: 0.31–0.53). This study identified 14 risk factors for malnutrition in elderly patients with diabetes. This meta-analysis improved our understanding of the prevalence and risk factors of malnutrition in elderly patients with diabetes. https://www.crd.york.ac.uk/PROSPERO/view/CRD420251034655, identifier CRD420251034655.
