A new study has revealed that age and body mass index or BMI affect the basal insulin needs for type 1 diabetes (T1D) patients.

The research included 67 in-patients diagnosed with
Type 1 diabetes. While confined in hospital, they received diabetic-friendly
meals and underwent basal insulin adjustments to maintain stable blood glucose
levels. Bolus insulin doses before meals were likewise adjusted to manage blood
glucose. The total daily insulin dose (TDD) and the percent of total daily
basal insulin (TBD) to TDD (%TBD/TDD) were calculated.
Based on the evaluation of the 3-day insulin
requirements, it showed that the TDD was 33.0 units, while TBD was 7.0 units.
The total bolus dose needed was 26.0 units. The resulting %TBD/TDD was 24.1%.
Researchers conducted the Pearson’s and Spearman’s
rank correlation analyses to identify factors linked to %TBD/TDD. They discovered
that BMI was directly and significantly correlated with %TBD/TDD, while age at
examination and at diabetes onset showed inverse correlations.
By using the multiple regression analysis eventually
confirmed the significant and independent roles of BMI and age at examination
in affecting %TBD/TDD. Diabetes duration and serum levels of C-peptides had no
impacts.
There are study limitations, however, included in its
retrospective and observational design, small study size, single-center data
resource, and limited generalizability.
According to researchers, it is important to set the
%TBD/TDD on an individual basis while considering patient background characteristics,
such as the BMI and age.
