Table 3. Odds ratios of hypertension in the Non-exe, Mod-exe, and Vig-exe groups according to sodium intake.

Groups	Age-adjusted Model		Multivariate Model 1		Multivariate Model 2
	OR	95% CI	OR	95% CI	OR	95% CI
Sodium intake ≥4000 mg/day
Non-exe	Reference		Reference		Reference
Mod-exe	0.63	0.47–0.85	0.63	0.43–0.91	0.66	0.45–0.96
Vig-exe	1.11	0.95–1.30	1.22	0.99–1.50	1.22	0.98–1.51
Sodium intake <4000 mg/day
Non-exe	Reference		Reference		Reference
Mod-exe	0.75	0.46–1.23	0.76	0.41–1.39	0.90	0.48–1.68
Vig-exe	1.07	0.82–1.39	1.29	0.91–1.83	1.33	0.92–1.92

The odds ratios for hypertension according to exercise groups were estimated by using logistic regression for both sodium intake groups. Multivariate model 1 was adjusted for age, BMI, fasting glucose, triglycerides, LDL-C, HDL-C, energy, and sodium intakes. Multivariate model 2 was adjusted for education, income, smoking, alcohol consumption, receiving education for hypertension, survey year, chronic disease status (those diagnosed with or taking medication(s) for the management of diabetes, stroke, myocardial infarction, angina pectoris, chronic renal failure, and cancers vs. those not) in addition to the factors of multivariate model 1. Odds ratios for each factor in each model were calculated with 95% Wald’s confidence intervals.
