Prevalence of hypovitaminosis D and associated factors in adolescent students of a capital of northeastern Brazil.
A high prevalence of hypov vitaminosis D is found in the analyzed population, especially in female adolescents, and the factors independently associated with hypovitaminosis D were found to be overweight/obese in boys and low calcium concentrations in girls.
[25-hydroxyvitamin D concentrations and blood pressure levels in hypertensive elderly patients].
The prevalence of inadequate vitamin D concentrations was related with higher blood pressure in elderly patients and greater fish weekly consumption influenced greater 25-hydroxyvitamin D concentration.
Vitamin D insufficiency/deficiency and its association with cardiometabolic risk factors in Brazilian adolescents.
A high proportion of adolescents presenting insufficiency/vitamin D deficiency was ssociated with cardiometabolic risk factors, and an evident relationship between the three indicators involved in overweight assessed in this study BMI, WC and AGR was revealed.
Variants RS1544410 and RS2228570 of the vitamin D receptor gene and glycemic levels in adolescents from Northeast Brazil.
This study showed a significant relation of glycemia with the distribution of rs1544410 polymorphism genotypes, and adolescents from the Northeast region of Brazil had a greater chance of blood glucose below the median.
200.000 IU of vitamin D does not reduce resting Blood Pressure and Inhibit Post-Exercise Hypotension in elderly women: a pilot study.
A megadose of vitamin D did not reduce RBP, promoted partial inhibition of systolic PEH and increased sympathovagal balance, and this increase was not observed in the placebo.
Relationship between BsmI polymorphism and VDR gene methylation profile, gender, metabolic profile, oxidative stress, and inflammation in adolescents.
It is concluded that the methylation profile of the VDR gene is not influenced by the different BsmI polymorphism genotypes, and that serum vitamin D and serum markers of oxidative stress and inflammation can modulate this profile.
