Compared To Other Blood Pressure Medications Diuretics Have Bone Protective Effect
MedicalResearch.com Interview with:

MedicalResearch.com: What is the background for this study?
Response: Hypertension (HTN) and osteoporosis (OP) are age-related disorders. Both increase rapidly in prevalence after age 65 years. Prior retrospective, post hoc studies have suggested that thiazide diuretics may decrease the risk of osteoporosis. These studies, by their nature, are open to bias. Moreover, these studies have not examined the effects of other anti HTN medications on osteoporosis.
Here we used a prospective blood pressure study of ~5 years duration to examine the effects of a thiazide diuretic, a calcium channel blocker and an ACE inhibitor on hip and pelvic fractures. We chose these fractures since they are almost always associated with hospitalization and thus their occurrence can be verified.
After the conclusion of the study we added another several years of follow up by querying medicare data sets for hip and pelvic fractures in those participants with medicare coverage after the study conclusion.
