NYU researchers find diabetes perceptions vary according to risk factors

Recent research published in The Diabetes Educator by Dr. Shiela Strauss, associate professor of nursing and co-director of the Statistics and Data Management Core for NYU's Colleges of Nursing and Dentistry, along with a team of NYU researchers, reveals differing perceptions among adult populations at-risk for diabetes that may offer new approaches to diabetes education and prevention.

"We found that there are differences in the perceptions of those who are at risk for diabetes that depend on the specific characteristics that place them at risk," said Strauss.

Illness perceptions, the organized cognitive representations and beliefs that people hold about a condition, are recognized as important determinants of self-care behaviors and outcomes in patients. The way that people mentally represent their conditions has a concrete effect on the way that they manage these conditions and therefore on their prognoses.

With illness perceptions strongly linked to patient outcomes, Strauss' research, the first in the field to examine illness perceptions in persons at-risk for diabetes based on their individual risk factors, may be influential in designing care to better fit patients on a case-by-case basis.

Strauss, along with Dr. Mary Rosedale and Ms. Navjot Kaur, assessed each participant's general diabetes knowledge and administered a questionnaire to measure eight dimensions of diabetes illness perceptions among the sample. These data were then used to examine statistically significant differences among the eight dimensions of diabetes illness perceptions according to the presence or absence of their diabetes risk factors.

Among the findings, researchers noted that compared to those who had a first-degree relative with diabetes, those who did not were less concerned that they might have diabetes, reported a poorer understanding of the disease, and were less emotionally affected by the possibility of a future diagnosis.

There was also a statistically significant difference in the same three components of illness perceptions according to Latino ethnicity. In particular, those of Latino ethnicity were more concerned that they might have diabetes, reported that they had a better understanding of diabetes, and were more affected emotionally by the possibility of having diabetes, when compared to those not of Latino ethnicity.

The study also found that individuals with a body mass index (BMI) of 25 kg/m2 or more believed that diabetes would have a greater effect on their lives if they developed it, and demonstrated a greater understanding of diabetes when compared to those with a lower BMI.

In addition, persons of at-risk races (black, Native American, Asian, Pacific Islander), as compared with those whose race did not place them at increased risk for diabetes, believed that diabetes would endure for less time, that they would have more personal control over diabetes, that treatment would help their illness, and that they had a better understanding of diabetes.
