The increasing use of insulin pump therapy over the last 15 years, particularly in children, has been driven by improvements in pump technology. Earlier this year the Scottish Government paid £3 million for hundreds of the devices amid concern about a "disappointing" uptake by health boards.
Debate has continued over the benefit of insulin injections, compared to pump therapy.
The new research, published in the journal Diabetologia, is the longest and largest study of its type.
Associate Professor Elizabeth Davis, of Princess Margaret Hospital for Children in Perth, Australia, and her colleagues matched 345 patients, aged two to 19 and with an average age of 11, on pump therapy to controls on injections.
Pump therapy reduced episodes of severe hypoglycaemia - dangerously low blood glucose - from 14.7 to 7.2 events per 100 patients per year. In contrast, severe hypoglycaemia increased in the non-pump group in the same period from 6.8 to 10.2 events per 100 patients per year.
Of the 345 patients on pump therapy, 38 ceased pump therapy during the course of the study.
Some children stop because they become tired of the extra attention needed to manage the pump or are concerned about the sight of the pump.
Dr Davis said: "This is the largest study of insulin pump use in children. Our data confirm that insulin pump therapy provides an improvement in glycaemic control which is sustained for at least seven years."
