BACKGROUND: There is a high prevalence of vitamin D deficiency in pregnancy worldwide, and variable availability of vitamin D-rich foods may affect the adequacy of vitamin D food intake in different regions. AIM: We analysed the relationship between place of residence and maternal food intake of vitamin D and calcium in West Sumatra, Indonesia. METHODS: This cross-sectional study was conducted in 203 pregnant women. Data collection was carried out in four districts in West Sumatra – two in coastal locations and two in mountainous locations – with subjects divided into groups based on their place of residence. The dietary intakes of pregnant women were assessed through a semi-quantitative food-frequency questionnaire (SQ-FFQ). RESULTS: The means of maternal vitamin D and calcium food intake were 7.92 ± 5.26 µg/day and 784.88 ± 409.77 mg/day, respectively. There were no reports of vitamin D supplement intake during pregnancy. A total of 86.7% and 89.7% of the study subjects had low vitamin D and calcium food intake status, respectively. There was a significant association between maternal vitamin D intake and place of residence (p = 0.02) and significant different mean levels of vitamin D food intake with the place of residence (9.04 vs 6.55 µg/day; p = 0.01). Mothers who had higher education levels had adequate calcium food intake (p = 0.015; OR: 0.295; 0.116–0.751). CONCLUSION: Low maternal vitamin D and calcium food intake were found to be common in West Sumatra, Indonesia and their differed between those residents in mountainous and in coastal areas.

Introduction: Indian population has a paradoxically high prevalence of vitamin D deficiency. Maternal vitamin D levels are related to outcomes of pregnancy for mother and foetus. To understand the need for screening and appropriate management decisions, data is needed from various regions of India to explore the magnitude of the problem. Aim: To evaluate the vitamin D levels in pregnant mothers and their newborns at a hospital catering to the affluent population in Mumbai. Materials and Methods: A cross-sectional study was conducted from August to December 2012. A 100 women of Indian origin, between 20-45 years of age and their newborns who were delivered at the Lilavati Hospital and Research Centre in Mumbai were included. Determination of 25 hydroxy (OH) vitamin D, serum calcium, albumin concentration was done in mothers just before delivery and newborns venous cord blood at the time of delivery. Pearson’s correlation test was used for determining relation between maternal and newborns vitamin D levels and Chi-square test for association of maternal vitamin D levels with their sun exposure and newborns birth weight. Results: The distribution of serum 25 (OH) vitamin D status in mothers was 75 deficient (75%), 13 insufficient (13%) and 12 sufficient (12%). Mean serum 25 (OH) vitamin D in mothers was 15.09 ng/mL. The distribution of serum 25 (OH) vitamin D levels in newborns were 78 deficient (78%), 13 insufficient (13%) and 9 sufficient (9%). Mean serum 25 (OH) vitamin D in neonates was 13.82 ng/mL. There was strong correlation between maternal and newborns serum 25 (OH) vitamin D levels with a Pearson correlation coefficient value of 0.94 and the p-value of <0.001. Conclusion: There was a high prevalence of vitamin D deficiency in pregnant mothers associated with hypovitaminosis D in newborns in this hospital-based study catering to affluent population from Mumbai.

Fractional Excretion Of Phosphate

AbstractObjectivesPhosphate is essential for skeletal mineralization, which is regulated by parathyroid hormone, calcitriol and fibroblast growth factor 23 (FGF23). Serum phosphate is physiologically higher in younger children, but factors that contribute to this physiological state are poorly understood. This study aimed to evaluate phosphate and its regulators in children compared with adults.Materials and methodsThe participants were children aged 3–11 years and adults older than 20 years of age. Biochemical parameters including calcium, phosphorus, alkaline phosphatase, FGF23, and vitamin D were measured. Fractional excretion of phosphate was calculated, using serum and urine phosphate and creatinine.ResultsThis cross-sectional study was conducted on 45 children (mean age: 9.0 ± 2.1) and 44 adults (mean age: 38.9 ± 11.1). The children had higher serum calcium, phosphate, alkaline phosphatase, and FGF23 (p < 0.001), but fractional excretion of phosphate was greater in adults (14.1 ± 5.7, 11.4 ± 4.4, p = 0.019, 95% confidence interval [CI]: −0.7 to −0.2). Of all individuals, 61.8% had vitamin D deficiency. By multiple regression analysis, entering age, calcium, phosphate, and vitamin D level, the only independent predictor of FGF23 was 1, 25 dihydroxy-vitamin D3 (β: 0.78, p < 0.001, 95% CI: 0.5–1.1, R2: 0.59 for children, and β: 0.59, p < 0.001, 95% CI: 0.5–1.4, R2: 0.45 for adults).ConclusionAs far as we know, there is little information regarding the role of FGF23 in physiologic state. In this cross-sectional study no association was found between FGF23 and urinary phosphate excretion in growing children. Further studies with more detail are essential to evaluate phosphate homeostasis during childhood.

Maximal Suppression

We aimed to assess the parathyroid hormone (PTH) concentration in pregnant women at the beginning of pregnancy (1st trimester) and within days before delivery (3rd trimester) and evaluate its determinants. From September 2014 through December 2015 in a cross-sectional study, 204 women in the 1st trimester of pregnancy and 203 women in the 3rd trimester of pregnancy were recruited. Blood samples were collected to measure PTH and circulating 25-hydroxy-vitamin D (25(OH)D) concentrations. Lifestyle and demographic data were collected using a questionnaire. Serum 25(OH)D and PTH were inversely correlated in both early and late pregnancy. Our analyses suggest that in the 3rd trimester of pregnancy, a 25(OH)D level of 18.9 ng/mL (47.3 nmol/L) could serve as an inflection point for the maximal suppression of PTH. Statistically significant determinants of PTH concentrations in multiple regression were 25(OH)D concentrations, season, multiparity and education of the partner (all p < 0.05) in early pregnancy. In late pregnancy, 25(OH)D concentrations and country of origin were statistically significant determinants of PTH concentrations (all p < 0.05). These factors and their effect on PTH appear to be vastly determined by 25(OH)D; however, they might also affect PTH through other mechanisms besides 25(OH)D.
