Overall , intervention groups obtained higher 25(OH)D concentration than controls and there was obvious dose – response effect between intake dose and 25(OH)D concentration .
Baseline 25(OH)D concentration and age were significant indicators for 25(OH)D concentration .
Conclusions Regional- and age-specific recommended dosages of VitD supplements for population to achieve optimal 25(OH)D concentrations have been suggested
Background / Objectives Optimal doses of vitamin D ( VitD ) supplement in different population s are unclear .
We aim to evaluate the relationship between VitD supplementation and post-intervention serum 25-hydroxyvitamin D [ 25(OH)D ] concentration , to provide a recommended dosage of VitD for achieving an optimal 25(OH)D concentration for different population s .
Effects of vitamin D supplementation on pulmonary function in postmenopausal women following an aquatic exercise program.
Objective This study sought to investigate the effects of vitamin D supplementation and aquatic exercise on pulmonary function in postmenopausal women . Material s and methods This prospect i ve and controlled study included 104 women ( 62 ± 6.5 years ) divided into three groups : a control group lacking vitamin D and calcium supplementation which remained sedentary ( CG ; n = 17 ) ; a control group receiving vitamin D and calcium supplementation which remained sedentary ( CDG , n = 33 ) ; and a group that completed aquatic exercises three times a week and received vitamin D and calcium supplementation ( DTG , n = 54 ) . Data before and after 6 months of the study were analyzed , including serum 25-hydroxyvitamin D ( 25(OH)D ) and calcium concentrations , peak expiratory flow ( PEF ) , forced vital capacity ( FVC ) , and cirtometry . Results We observed significant increases in 25(OH)D concentrations in CDG ( 52.9 ± 2.4 to 69.1 ± 2.2 ; nmol/L ; p < 0.0001 ) and DTG groups ( 55.5 ± 3 to 71.5 ± 3 nmol/L ; p < 0.0001 ) . PEF increased by 7 ± 2 % ( p = 0.0080 ) in CDG group and 11 ± 2 % ( p < 0.0001 ) in DTG group , whereas FVC increased by 7 ± 2 % ( p = 0.0016 ) in the CDG group and 10 ± 2 % ( p < 0.0001 ) in the DTG group , whereas CG had no changes in any of these parameters . The increment value of cirtometry in DTG group ( + 43 ± 3 % ) were significantly ( p < 0.0001 ) higher than those in CG ( -4 ± 8 % ) and CDG ( + 4 ± 9 % ) groups . Conclusion Our data suggest that vitamin D supplementation improves pulmonary function parameters in postmenopausal women
