Vitamin D levels and cardiometabolic risk factors in Portuguese adolescents

Abstract

Although a significant increase in total and LDL cholesterol was observed for lower 25(OH)D levels, and an increased odds of high BMI was observed for those with a lower vitamin D intake, no significant association was observed between vitamin D levels and metabolic syndrome.

Relationship between dietary vitamin D and serum 25-hydroxyvitamin D levels in Portuguese adolescents

“…We found a weak relationship between dietary vitamin D intake and serum 25(OH)D concentration, which might be (15) . explained by the low levels observed for both intake and serum 25(OH)D compared with the recommendations (3,17) , as previously reported in this sample (18) . These results are in agreement with several studies that have identified a high prevalence of vitamin D intake inadequacy and serum 25(OH)D insufficiency in otherwise healthy adults and children living in North America (19,20) and Europe (7,8,(21)(22)(23) .…”

Association of Serum 25-Hydroxyvitamin D Concentration with Pulmonary Function in Young Adults

“…From the 2159 participants at baseline, 1716 (79.5%) were re-evaluated at 17 years and 1318 (61.0%) were re-evaluated at 21 years. From the 1204 subjects that performed the three evaluations, due to budgetary constraints, serum 25(OH)D concentration was determined in a sub-sample of 559 individuals (these 559 subjects were randomly chosen among the ones that have a blood sample collected in all three evaluations) [ 22 ]. From those, 58 participants without assessment of pulmonary function at 21 years and two pregnant women were excluded.…”

Vitamin D in adolescence: evidence-based dietary requirements and implications for public health policy

“…adolescence on these health outcomes in the short-and long-term (53) . inversely associated with total and low-density lipoprotein (LDL) cholesterol concentrations (54,55) , 161 glucose (56,57) and systolic blood pressure (54,56,58,59) and positively correlated with high-density 162 lipoprotein (HDL) cholesterol (23,57,59) , although not consistently (60,61) . Furthermore, vitamin D 163 status below 50 nmol/l has been associated with an increased prevalence of metabolic syndrome in 164 12-19 year old adolescents in the United States (56,58) , however no association was found in 13 year…”
