BACKGROUND AND OBJECTIVES: Population-based data on urinary @entity460 excretion are scarce. The association of serum @entity460 and circulating levels of @entity560 [25(OH)D2 or D3] with urinary @entity460 excretion in @entity1 and @entity1 from a population-based study was explored. DESIGN, SETTINGS, @entity1 , _ MEASUREMENTS: Multivariable linear regression was used to explore factors associated with square root-transformed 24-hour urinary @entity460 excretion (milligrams per 24 hours) taken as the dependent variable with a focus on month-specific @entity560 tertiles and serum @entity460 in the Swiss Survey on Salt Study. RESULTS: In total, 624 @entity1 and 669 @entity1 were studied with mean ages of 49.2 and 47.0 years, respectively (age range=15-95 years). Mean urinary @entity460 excretion was higher in @entity1 than in @entity1 (183.05 versus 144.60 mg/24 h; P<0.001). In adjusted models, the association (95% confidence interval) of square root urinary @entity460 excretion with protein-corrected serum @entity460 was 1.78 (95% confidence interval, 1.21 to 2.34) mg/24 h per milligram per deciliter in @entity1 and 0.59 (95% confidence interval, -0.11 to 1.29) mg/24 h per milligram per deciliter in @entity1 . @entity1 in the third @entity14282 tertile had higher square root urinary @entity460 excretion than @entity1 in the first tertile (0.99; 95% confidence interval, 0.36 to 1.63 mg/24 h per nanogram per milliliter), and the corresponding association was 0.32 (95% confidence interval, -0.22 to 0.85) mg/24 h per nanogram per milliliter in @entity1 . These sex differences were more marked under conditions of high urinary @entity1372 or @entity1133 excretions. CONCLUSIONS: There was a positive association of serum @entity460 with urinary @entity460 excretion in @entity1 but not @entity1 . Vitamin 25(OH)D3 was associated with urinary @entity460 excretion in @entity1 but not @entity1 . These results suggest important sex differences in the hormonal and dietary control of urinary @entity460 excretion.
