Abstract

PAULA, Juliana Santos; BRAGA, Letícia Dinis; MOREIRA, Rodrigo Oliveira  and  KUPFER, Rosane. Correlation between parameters of self-monitoring of blood glucose and the perception of health-related quality of life in patients with type 1 diabetes mellitus. Arch. Endocrinol. Metab. [online]. 2017, vol.61, n.4, pp.343-347.  Epub Nov 24, 2016. ISSN 2359-4292.  https://doi.org/10.1590/2359-3997000000222.

Objective

The aim of this study was to evaluate how different parameters of short-term glycemic control would correlate with the perception of health-related quality of life (HRQoL) in patients with type 1 diabetes mellitus (T1D).

Subjects and methods

A total of 50 T1D patients aged 18 to 50 years were evaluated with the questionnaires Problem Areas in Diabetes (PAID) scale and Diabetes Quality of Life (DQOL) measure after 30 days of self-monitoring of blood glucose (SMBG). Glycemic control was evaluated using glycated hemoglobin (HbA1c), mean glucose levels (MGL) in the prior month’s data from SMBG (Accu-Check 360o), number of hypoglycemic episodes (< 70 mg/dL and < 50 mg/dL), and glycemic variability (GV).

Results

PAID correlated positively with MGL (r = 0.52; p < 0.001) and HbA1c (r = 0.36; p < 0.0097), but not with GV (r = 0.17; p = 0.23) or number of hypoglycemic episodes (r = 0.15; p = 0.17 for glucose < 70 mg/dL and r = 0.02; p = 0.85 for glucose < 50 mg/dL). After multiple linear regression, only MGL remained independently related to PAID scores. DQOL scores had a positive correlation with MGL (r = 0.45; p = 0.001), but not with HbA1c (r = 0.23; p = 0.09), GV (r = 0.20; p = 0.16), or number of hypoglycemic episodes (r = 0.06 p = 0.68).

Conclusion

In T1D patients, MGL, but not HbA1c or number hypoglycemic episodes, was the glycemic control parameter that best correlated with short-term perception of HRQoL.
