INS and Hypoglycemia: There are conflicting reports about whether maternal treatment affects the risk of neonatal hypoglycaemia with some studies finding increased risk if mothers required medical treatment17 while others find no significant difference in risk between neonates of diet-treated and insulin-treated mothers.18 Although we found significant temporal variation in the risk of neonatal hypoglycaemia when treated as a categorical variable, it is important to note the annual range of mean lowest capillary glucose reading was <0.15 mmol/L and there was no significant temporal variation.
