Unknown cause(s) of primary osteoporosis

Determine the cause(s) of primary osteoporosis cases that are not attributable to aging or menopause, in order to clarify the etiology of primary osteoporosis beyond these known factors.

Background

The paper distinguishes osteoporosis into primary and secondary forms based on etiology and notes that while aging and menopause are recognized contributors to primary osteoporosis, some primary cases have an unspecified cause. Clarifying these unknown causes would refine the classification and understanding of primary osteoporosis and potentially guide prevention and treatment strategies.
