The National Osteoporosis Foundation’s position statement on peak bone mass development and lifestyle factors: a systematic review and implementation recommendations
AbstractLifestyle choices influence 20–40 % of adult peak bone mass. Therefore, optimization of lifestyle factors known to influence peak bone mass and strength is an important strategy aimed atExpand

Height adjustment in assessing dual energy x-ray absorptiometry measurements of bone mass and density in children.
CONTEXT In children, bone mineral content (BMC) and bone mineral density (BMD) measurements by dual-energy x-ray absorptiometry (DXA) are affected by height status. No consensus exists on how toExpand

Weight and Metabolic Outcomes After 2 Years on a Low- Carbohydrate Versus Low-Fat Diet:
Previous studies have demonstrated that low-carbohydrate diets achieve greater short-term (6 months) weight loss than low-fat diets. Longer-term (1 to 2 years) data have been inconsistent. WeightExpand

Risk factors for low serum 25-hydroxyvitamin D concentrations in otherwise healthy children and adolescents.
BACKGROUND Serum 25-hydroxyvitamin D [25(OH)D] concentrations serve as a biomarker for vitamin D stores. Prior studies have not examined the risk factors for low vitamin D concentrations in aExpand

Proximal femur bone geometry is appropriately adapted to lean mass in overweight children and adolescents.
It is unclear if the bones of overweight children are appropriately adapted to increased loads. The objective of this study was to compare bone geometry in 40 overweight (body mass index [BMI] > 85thExpand
