Association Between Dietary Salt Intake and Plasma Glucose

Salt Intake*	β	95% CI	P
	Fasting plasma glucose

>8 g/day	0.731	0.292, 1.2	0.001
Adjusted modela

>8 g/day	2.3	0.472, 4.1	0.013
	2-hour postprandial plasma glucose
Crude model
6–8 g/day	1.4	0.625, 2.2	<0.001
>8 g/day	1.5	0.742, 2.3	<0.001

Notes: ≤6 g/day salt intake is the reference category in the model. ^aAdjusted for sex, age, education, physical activity, smoking, drinking, creatinine, uric acid, lipids, medication and interactions.
