Salt intake and mental distress among rural community-dwelling Japanese men

Table 2 Odd ratios (OR) and 95 % confidence interval (CI) for mental distress in relation to estimated salt intake level tertiles

	Estimated daily salt intake tertiles			P for trend	1SD increment in estimated daily salt intake (2.0 g/day)
	Tl (low)	T2	T3 (high)	P for trend	1SD increment in estimated daily salt intake (2.0 g/day)
No. at risk	338	338	338
No. of cases (percentage)	45 (13.3)	29 (8.6)	23 (6.8)
Age-adjusted OR	1.00	0.61 (0.37–1.00)	0.47 (0.28–0.79)	0.004	0.71 (0.57–0.88)
Multivariable OR	1.00	0.65 (0.39–1.09)	0.50 (0.29–0.88)	0.014	0.74 (0.59–0.93)

Multivariable OR: adjusted further for body mass index, systolic blood pressure, antihypertensive medication use, thyroid disease, alcohol consumption, smoking status, AST, triglycerides, HDL-cholesterol, HbA1c, antidiabetic medication use, and GFR. The median values of estimated daily salt intake tertiles were 7.0, 8.8, and 10.8 g/day
