ABSTRACT
Objective:
To evaluate the
association between
knowledge about the
disease, adherence to
self-care, and
glycemic control in people diagnosed with
type 1 diabetes mellitus. Subjects and
methods:
A
cross-sectional study of
patients aged over 18 years diagnosed with
type 1 diabetes mellitus, treated at an
outpatient clinic of a Brazilian
university hospital. Participants with other types of diabetes,
cognitive impairment,
pregnancy, and
outpatient discharge were excluded. Data were collected from January to March 2021 (by
telephone call), with questions about the participants' profile, diabetes
knowledge questionnaire (DKN-A), and
self-care inventory revised (SCI-R) translated into and adapted for Brazilian Portuguese.
Data analysis involved chi-square
associations, Mann-Whitney U tests, and Poisson regression.
Results:
Among 198
adult participants, the mean age was 42 ± 12 years, 53.5% were
women, the mean
glycated hemoglobin was 8.6 ± 1.6%, 140 (70.8%) had satisfactory
knowledge about diabetes, 65 (32.8%) had adherence to
self-care, and 46 (23.2%) had adequate
glycemic control. We found an
association between
knowledge and adherence to
self-care (p < 0.001).
Knowledge was not associated with
glycemic control (p = 0.705).
Conclusion:
Knowledge about diabetes was associated with greater adherence to
self-care in people with
type 1 diabetes mellitus, but it did not reflect in better
glycemic control.
