“…Prior fortification After fortification Prior fortification After fortification Prior fortification After fortification P-value The present findings cannot be attributed to a simple cohort effect, as both dietary intake and serum 25-hydroxyvitamin D concentration were as previously reported in older children and adolescents in the same area of Finland Lagström et al, 1999;(Lehtonen-Veromaa et al, 1999;Laitinen et al, 2005) and also in other countries (Fuleihan et al, 2001;Gordon et al, 2004). According to our results and previous observations (Antoniucci et al, 2005), the serum 25-hydroxyvitamin D concentration appears to be stable during storage, thus not affecting the measurements conducted to estimate vitamin D status.…”

“…Indeed, a low dietary intake has been reported particularly in children, the vitamin D intake being only half of that recommended (Lagström et al, 1999;LehtonenVeromaa et al, 1999;Laitinen et al, 2005). Additionally, a low serum 25-hydroxyvitamin D concentration, indicator of vitamin D status, has been measured in European and US children and adolescents, again particularly during wintertime (Lamberg-Allardt et al, 1986;Lehtonen-Veromaa et al, 1999;Gordon et al, 2004;Ladhani et al, 2004), this suggesting an inadequate dietary intake.…”

Results: The mean intake of vitamin D was higher the after initiation of fortification (mean (95% confidence interval (CI)); 4.5 (3.8-5.1) mg) than before it (2.1 (95% CI 1.8-2.3) mg; Po0.001), although there were no differences in consumption of the main food sources of vitamin D between the two cohorts. The difference between the cohorts was also evident when the intake of vitamin D was adjusted for energy intake (0.78 (95% CI 0.70-0.90) and 0.37 (95% CI 0.32-0.42) mg/MJ after and before fortification, respectively, Po0.001). After fortification, the mean intake approached that recommended, but was achieved by only 30.6% of the children. Equally, the serum 25-hydroxyvitamin D concentration was higher after fortification (64.9 (95% CI 59.7-70.1) nmol/l) compared to prior it (54.7 (95% CI 51.0-58.4) nmol/l; P ¼ 0.002).

Objective: The aim was to investigate autumn vitamin D intake and status in 7-year-old Icelanders, fitting BMI and cardiorespiratory fitness as predictors. Design: Three-day food records and fasting blood samples were collected evenly from September to November, and cardiorespiratory fitness was measured with an ergometer bike. Conclusions: A minority of children followed the vitamin D recommendations and 65 % had suboptimal vitamin D status during the autumn. Week of autumn was more strongly associated with vitamin D status than diet or cardiorespiratory fitness, which associated with vitamin D status to a similar extent. These results demonstrate the importance of sunlight exposure during summer to prevent suboptimal vitamin D status in young schoolchildren during autumn in northern countries. An increased effort is needed for enabling adherence to the vitamin D recommendations and increasing outdoor activities for sunlight exposure.

“…According to these criteria, metabolic syndrome is diagnosed when an individual has three or more of the following components: (i) WC $90th percentile for age and sex; (ii) TAG $110 mg/dl; (iii) HDL-C #40 mg/dl; (iv) either SBP or DBP $90th percentile for age and sex, use of blood pressure-lowering medication or a previous diagnosis of hypertension; and (v) FPG $100 mg/dl, current diabetes status or current use of insulin or hypoglycaemic medication. (8,9) . We used univariate and hierarchical multivariate logistic regression analyses to assess the associations of serum 25(OH)D concentration with the prevalence of metabolic syndrome and its individual components, such as abdominal obesity, high blood pressure, hyperglycaemia, hypertriacylglycerolaemia, low HDL-C, and overweight or obesity.…”

Objective: Vitamin D insufficiency is known to be related to cardiometabolic disorders; however, the associations among serum Results: Vitamin D insufficiency, defined as 25(OH)D concentration ,50 nmol/l, was found in 75?3 % of Korean adolescents and was associated with an increased risk of the prevalence of metabolic syndrome. Waist circumference and BMI were the most closely correlated cardiometabolic components of metabolic syndrome according to serum 25(OH)D status, but no significant relationship was found between serum 25(OH)D concentration and insulin resistance or for the risks for high blood pressure, hyperglycaemia, reduced HDL-cholesterol or hypertriacylglycerolaemia, with or without adjustment for confounding variables. Conclusions: Low serum 25(OH)D concentration appears to be associated with several cardiometabolic risk factors and an increased risk of the prevalence of metabolic syndrome in Korean adolescents.

Prevalence of Vitamin D Deficiency Among Healthy Adolescents

Abstract: Vitamin D deficiency was present in many US adolescents in this urban clinic-based sample. The prevalence was highest in African American teenagers and during winter, although the problem seems to be common across sex, season, and ethnicity.
