The HR (95% CI) of developing abdominal obesity based on the best knots of SZn concentrations

	Male		Female
SZn (µg/dL)	102.4-129.9	>129.9	102.6-127.5	>127.5
Crude	1.17 (0.71–1.91)	1.58 (1.00-2.51)	0.78 (0.58–1.06)	0.76 (0.56–1.04)
Model 1	0.63 (0.37–1.06)	1.08 (0.67–1.74)	0.79 (0.58–1.08)	0.66 (0.48–0.91)
Model 2	0.65 (0.38–1.09)	1.14 (0.71–1.84)	0.79 (0.58–1.08)	0.66 (0.47–0.91)
Data are HRs and 95% CI Proportional Cox regression was used; SZn < 102.4 and < 102.6 µg/dL, in male and female, was considered as reference, respectively. Model 1, adjusted for age, and baseline body weight Model 2, additionally adjusted smoking, menopause status, diabetes, and physical activity level. SZn; serum zinc
