Model of Li et al for Predicting Post-Partum Type 2 Diabetes in a Chinese Woman with Gestational Diabetes

Description

Li et al reported a model for predicting post-partum type 2 diabetes in a Chinese woman with gestational diabetes. This can help to identify a woman who should have closer monitoring. The authors are from Tianjin Women's and Children's Health Center, Capital Institute of Pediatrics and Peking Union Medical College in China and Pennington Biomedical Research Center in Louisianna.

Patient selection: Chinese woman with type 2 diabetes

Parameters:

(1) family history of diabetes

(2) BMI category before pregnancy

(3) pregnancy-induced hypertension (PIH)

(4) 2-hour 75-gram glucose tolerance test category at 26-30 gestational weeks

Parameter	Finding	Points
family history of diabetes	no	0
	yes	30.9
BMI category	< 24 kg per sq m	0
	24 to 27.99	30.5
	>= 28	57
PIH	no	0
	yes	53.6
2-hour GTT	7.8 to 8.44 mmol/L	0
	8.5 to 11.099 mmol/L	47
	>= 11.1 mmol/L	100

total score =

= SUM(points for all of the parameter)

Interpretation:

• minimum score: 0

• maximum score: 241.5

value of X =

= (0.0001056 * ((score)^2)) - (0.002609 * (score)) - 2.686

probability of post-natal diabetes =

= 1 / (1 + EXP((-1) * X))
