Diabetes Numeracy and Blood Glucose Control: Association With Type of Diabetes and Source of Care

Abstract: In BriefLimited diabetes numeracy may be an important factor affecting diabetes care and treatment adherence. This study assessed the relationship between the Diabetes Numeracy Test (DNT-15 score) and patient and treatment variables. Patients who had type 1 diabetes and those who received care from specialty centers had higher levels of numeracy, but this did not translate into improved glucose control.

“…Numeracy skills, i.e., “the ability to understand and use numbers in daily life”, are used by diabetes patients to assist with self-management tasks such as understanding glucose measurements, calculating medication doses (especially insulin) and interpreting dietary recommendations and nutrition labels [ 60 ]. High performance on a numeracy test developed and tested for diabetes has been found to have a significant correlation with higher diabetes knowledge and higher perceived self-efficacy [ 60 , 61 ] but the association between numeracy skills and glycemic control has not been consistently demonstrated [ 62 , 63 , 64 , 65 ]. In populations which face language barriers, numbers can become the single most important criterion for understanding disease status.…”

“…4 This presents problems with elevated glucose levels and glycemic variability. Two-thirds of people taking insulin cannot calculate their doses correctly 5,6 even if they know their blood glucose and know how much carbohydrate they are eating. This presents some significant challenges that require tools to help people manage their insulin better.…”

“…In rural southeastern Ohio, diabetes rates far exceed both the national (19.9% vs. 9.4%) [ 4 , 5 ] and state prevalence (11.0%) [ 6 ]. Here, diabetes patients are more likely to have a delayed diagnosis, limited access to health care, lower health literacy, and lower empowerment [ 7 , 8 ]. Moreover, the Appalachian counties located in southeastern Ohio are designated as economically “distressed,” with nearly a third of residents living below the poverty line [ 1 ].…”
