One or more: fasting glucose > 5.27 mmol/L, Glucose Challenge Test or single 1 h glucose > 7.21 mmol/L, 1 h glucose > 9.99 mmol/L if a 2 and 3 h glucose were recorded on same day, 2 h glucose > 8.6 mmol/L, 3 h glucose > 7.77 mmol/L, A1C > 6.0% (42 mmol/mol), random glucose > 7.21 mmol/L, Any + urine glucose.

Deliveries after 10/8/2015 were excluded to allow everyone the opportunity for 84 days (12 weeks) post-delivery records
