Background and aim: The 25OHD concentration at which intact parathyroid hormone (iPTH) is maximally suppressed and below which PTH begins to rise (inflection point) has been used to define optimum 25OHD concentration. While it is not known if the lower 25OHD levels in obese children are associated with a PTH increase in the same manner as it is in normal weight children, we aimed to study the relation between circulating PTH and 25OHD levels and to search for a 25OHD threshold...
