          Abstract

          Abstract Objectives: low vitamin D during pregnancy is common and could adversely affect health outcomes. This study evaluated vitamin D status during pregnancy and early in life, and its association with glucose metabolism. Methods: maternal serum 25(OH)D, glucose, and insulin levels were measured longitudinally during pregnancy in Hispanic women with overweight/obesity (n = 31) and their infants at birth and 4 months. Results: insulin and HOMA-IR levels were higher among women with vitamin D below adequate levels compared to those with adequate levels in pregnancy (p < 0.05). Late in pregnancy, as vitamin D increased by one unit (ng/mL), insulin decreased by 0.44 units and HOMA-IR by 0.09 units. Maternal vitamin D late in pregnancy was correlated with infant vitamin D levels at birth (r = 0.89; p < 0.01) and 4 months (r = 0.9; p = 0.04), and with glucose (r = 0.79; p = 0.03) and insulin (r = 0.83; p = 0.04) at 4 months. Conclusion: maternal vitamin D status was associated with maternal and infant glucose metabolism in this sample.

          Resumen Objetivos: un bajo nivel de vitamina D durante el embarazo es común y puede tener consecuencias adversas en la salud. Este estudio evaluó el nivel de vitamina D en mujeres embarazadas y sus bebés, así como su asociación con los marcadores de glucosa. Métodos: los niveles séricos de 25(OH)D, glucosa e insulina se midieron longitudinalmente en mujeres embarazadas hispanoamericanas con sobrepeso/obesidad (n = 31) y en sus bebés, desde el nacimiento hasta los 4 meses de edad, en Puerto Rico. Resultados: los niveles maternos de insulina y HOMA-IR eran mayores en las mujeres con niveles de vitamina D por debajo de lo considerado adecuado, comparado con aquellas con niveles adecuados durante todo el embarazo (p < 0,05). Al final del embarazo, a medida que los niveles de vitamina D aumentaron, por cada unidad (ng/mL) de aumento, la insulina disminuyo en 0,44 unidades y el HOMA-IR en 0,09 unidades. El nivel de vitamina D al final del embarazo se correlacionó con los niveles del bebé al nacer (r = 0,89; p < 0,01) y a los 4 meses (r = 0,9; p = 0,04), y con los niveles de glucosa (r = 0,79; p = 0,03) e insulina (r = 0,83; p = 0,04) a los 4 meses. Conclusión: el nivel materno de vitamina D se asoció con los marcadores maternos e infantiles de glucosa en esta muestra.

          Evaluation, treatment, and prevention of vitamin D deficiency: an Endocrine Society clinical practice guideline.

          The objective was to provide guidelines to clinicians for the evaluation, treatment, and prevention of vitamin D deficiency with an emphasis on the care of patients who are at risk for deficiency. The Task Force was composed of a Chair, six additional experts, and a methodologist. The Task Force received no corporate funding or remuneration. Consensus was guided by systematic reviews of evidence and discussions during several conference calls and e-mail communications. The draft prepared by the Task Force was reviewed successively by The Endocrine Society's Clinical Guidelines Subcommittee, Clinical Affairs Core Committee, and cosponsoring associations, and it was posted on The Endocrine Society web site for member review. At each stage of review, the Task Force received written comments and incorporated needed changes. Considering that vitamin D deficiency is very common in all age groups and that few foods contain vitamin D, the Task Force recommended supplementation at suggested daily intake and tolerable upper limit levels, depending on age and clinical circumstances. The Task Force also suggested the measurement of serum 25-hydroxyvitamin D level by a reliable assay as the initial diagnostic test in patients at risk for deficiency. Treatment with either vitamin D(2) or vitamin D(3) was recommended for deficient patients. At the present time, there is not sufficient evidence to recommend screening individuals who are not at risk for deficiency or to prescribe vitamin D to attain the noncalcemic benefit for cardiovascular protection.

            The role of vitamin D and calcium in type 2 diabetes. A systematic review and meta-analysis.

            Altered vitamin D and calcium homeostasis may play a role in the development of type 2 diabetes mellitus (type 2 DM). EVIDENCE ACQUISITION AND ANALYSES: MEDLINE review was conducted through January 2007 for observational studies and clinical trials in adults with outcomes related to glucose homeostasis. When data were available to combine, meta-analyses were performed, and summary odds ratios (OR) are presented. Observational studies show a relatively consistent association between low vitamin D status, calcium or dairy intake, and prevalent type 2 DM or metabolic syndrome [OR (95% confidence interval): type 2 DM prevalence, 0.36 (0.16-0.80) among nonblacks for highest vs. lowest 25-hydroxyvitamin D; metabolic syndrome prevalence, 0.71 (0.57-0.89) for highest vs. lowest dairy intake]. There are also inverse associations with incident type 2 DM or metabolic syndrome [OR (95% confidence interval): type 2 DM incidence, 0.82 (0.72-0.93) for highest vs. lowest combined vitamin D and calcium intake; 0.86 (0.79-0.93) for highest vs. lowest dairy intake]. Evidence from trials with vitamin D and/or calcium supplementation suggests that combined vitamin D and calcium supplementation may have a role in the prevention of type 2 DM only in populations at high risk (i.e. glucose intolerance). The available evidence is limited because most observational studies are cross-sectional and did not adjust for important confounders, whereas intervention studies were short in duration, included few subjects, used a variety of formulations of vitamin D and calcium, or did post hoc analyses. Vitamin D and calcium insufficiency may negatively influence glycemia, whereas combined supplementation with both nutrients may be beneficial in optimizing glucose metabolism.
