A study published in September of 2010 in the Journal of Clinical Nutrition showed a positive correlation between low Vitamin D serum levels and an increase in obesity. The most interesting component of this study of the 400+ school children was performed on Columbian children in 2006 for approximately 30 months.
The recent deluge of reporting on vitamin d deficiency can't be missed. It is known that the sun provides us our most bio-available form of vitamin D and most particularly, higher amounts are obtained while living near or below the equator. Such is Columbia, right above the equator proving that at serum levels below 50, these children are mimicking our North American hysteria and reducing sun exposure.
Improve immunity, reduce adiposity, prevent disease, aches, pains and maintain strong bone structure with vitamin d.
Supplementing with Vitamin D3 drops in the form of cholecalciferol is incredibly important and in my opinion, "non-negotiable" in your supplement regimen.
2000-5000IU are recommended daily for a healthy adult dose and 800-2000IU for baby and child.
Background: Cross-sectional studies have indicated that vitamin D serostatus is inversely associated with adiposity. It is unknown whether vitamin D deficiency is a risk factor for the development of adiposity in children.
Objective: We investigated the associations between vitamin D serostatus and changes in body mass index (BMI; in kg/m2), skinfold-thickness ratio (subscapular-to-triceps), waist circumference, and height in a longitudinal study in children from Bogota, Colombia.
Design: We quantified plasma 25-hydroxyvitamin D [25(OH)D] concentrations in baseline samples of a randomly selected group of 479 schoolchildren aged 5–12 y and classified vitamin D status as deficient [25(OH)D concentrations <50 nmol/L], insufficient [25(OH)D concentrations ≥50 and <75 nmol/L], or sufficient [25(OH)D concentrations ≥75 nmol/L]. We measured anthropometric variables annually for a median of 30 mo. We estimated the average change in each anthropometric indicator according to baseline vitamin D status by using multivariate mixed linear regression models.
Results: Vitamin D–deficient children had an adjusted 0.1/y greater change in BMI than did vitamin D–sufficient children (P for trend = 0.05). Similarly, vitamin D–deficient children had a 0.03/y (95% CI: 0.01, 0.05/y) greater change in subscapular-to-triceps skinfold-thickness ratio and a 0.8 cm/y (95% CI: 0.1, 1.6 cm/y) greater change in waist circumference that did vitamin D–sufficient children. Vitamin D deficiency was related to slower linear growth in girls (−0.6 cm/y, P = 0.04) but not in boys (0.3 cm/y, P = 0.34); however, an interaction with sex was not statistically significant.
Conclusion: Vitamin D serostatus was inversely associated with the development of adiposity in school-age children.
