Factors prevalent among CLWH that can compromise bone density include low muscle mass and strength, poor nutrition, inadequate dietary calcium and vitamin D deficiency. HIV promotes dysregulated systemic immune activation which leads to an imbalance in osteoblastic/osteoclastic activity resulting in ...
inadequate intake of vitamins and minerals due to poor diet as a major contributing factor to many child health problems in the US and around the world, including anemia (low iron), hypothyroid (low iodine), scurvy (vitamin C deficiency), and rickets (calcium and/or vitamin D deficiency). ...
