NCT02355717
The proposed research brings together complementary expertise to systematically elucidate the longitudinal effects of (1) total and regional body fat and (2) the metabolic impairment that accompanies obesity on bone development during growth. The contribution of this research will be significant because it will provide a solid foundation for understanding the influence of fat (total and regional distribution) on overall bone strength, and whether insulin resistance, beta-cell dysfunction, abnormal lipids, and inflammation could be underpinning factors in the fat-bone strength relationship via effects on bone modeling activity. This knowledge will provide critical information needed to maximize potential therapeutic interventions to counter the linked risks of obesity and osteoporosis, both major public health concerns.
NCT02959762
Animal studies have found that vitamin K-dependent proteins matrix Gla protein and osteocalcin beneficially influence lipid and glucose metabolism, respectively. However, this concept has not been tested in humans at risk for dyslipidemia and diabetes risk. Vitamin K supplementation presents an opportunity to test the hypothesized link between the vitamin K-dependent proteins and markers of lipid and glucose metabolism. The investigators will conduct an 8-week vitamin K intervention (to manipulate carboxylation of matrix Gla protein and osteocalcin) and determine its effects on markers of dyslipidemia and diabetes risk. Sixty obese children will be randomly allocated to either the control group receiving placebo or the low-dose (45 mcg/d) or high-dose group (90 mcg/d) receiving vitamin K (menaquinone-7).
