Researchers looked at nutrition education programs designed for deaf and hard-of-hearing people. They found only eight studies on this topic from the past 24 years, showing there’s a big gap in research. Most programs that were tested helped people eat better and improve their health. However, the researchers say we need much better programs that use proven methods for changing eating habits and that truly understand deaf culture and communication needs.

The Quick Take

  • What they studied: How well nutrition education programs work for deaf and hard-of-hearing people
  • Who participated: Eight different studies involving deaf and hard-of-hearing people of various ages who participated in nutrition programs
  • Key finding: Seven out of eight programs helped people improve their eating habits and health, but there are surprisingly few programs designed for this community
  • What it means for you: If you’re deaf or hard-of-hearing, you may have limited access to nutrition education that truly meets your communication needs

The Research Details

This was a systematic scoping review, which means researchers searched through scientific databases to find all studies about nutrition education for deaf and hard-of-hearing people published between 2000 and 2024. They used a careful search method called PICOS to make sure they didn’t miss important studies. Out of all the research they looked through, they only found eight studies that met their criteria.

This type of research is important because it shows us what’s already been tried and what works. It also reveals gaps where more research is needed.

The researchers used a thorough search method across 16 different databases, which means they likely found most relevant studies. However, finding only eight studies over 24 years suggests this is an understudied area.

What the Results Show

Out of eight nutrition programs studied, seven showed that participants improved their eating habits and health after completing the programs. The programs used different approaches - some focused on general healthy eating, while others targeted specific issues like making better food choices or increasing exercise. Most programs were taught in person by public health professionals and nutritionists. However, only one study used a proven theory about how to change people’s behavior, which is concerning because these theories help make programs more effective.

The programs varied widely in their approach, location, and who participated. Some addressed multiple aspects of eating habits, while others focused on specific concerns. All programs tried to address communication barriers that deaf and hard-of-hearing people face when accessing health information.

This appears to be the first comprehensive review of nutrition education specifically for deaf and hard-of-hearing populations, highlighting how little attention this important health issue has received in research.

The biggest limitation is that there were very few studies to review, making it hard to draw strong conclusions. The studies also varied greatly in their methods, making them difficult to compare. Most studies didn’t follow up with participants long-term to see if the benefits lasted.

The Bottom Line

Healthcare providers and educators should develop more nutrition programs specifically designed for deaf and hard-of-hearing people, using proven behavior change theories and truly accessible communication methods

Deaf and hard-of-hearing individuals seeking nutrition education, healthcare providers, public health professionals, and researchers interested in health equity

Benefits from existing programs appeared relatively quickly, but more research is needed to understand long-term effects
