Persons with Type 1 diabetes need continuous exogenous insulin
supply throughout their life. Determining the optimal
insulin treatment in relation to diet and physical activity is one
of the main goals of diabetes management; but is difficult;
especially for vulnerable populations; such as adolescents.
Erroneous treatment may result in both repeated and severe
low blood glucose events. Continuous glucose monitoring
(CGM) may help in avoiding these events; but is inaccurate
compared to traditional glucose monitoring. Models have
been developed to significantly improve C’s detection of
insulin-induced events by using information from the CGM
signal itself. Additional temporal data on insulin doses; diet
and physical activity may improve hypoglycaemia prediction
models. In this research; we present and pilot test a study in
which a smartphone was used to obtain these data. Data from
one female was obtained over a period of two days. CGM and
continuous physical activity accelerometry data were collected with minimum and no dropouts; respectively. The collection
of diet; insulin and blood glucose data; also; proceeded without
problems. These results indicate that it is possible to collect
glucose; diet; insulin and physical activity data of high
quality. These data will facilitate further development of models
for the detection and prediction of low blood glucose.
