Summary

The purpose of this study is to identify the best way to prevent bone loss in the first years after menopause. The HOPE study will compare bone loss at 12 months in women: 1) who take calcium and vitamin D only; 2) who take calcium and vitamin D plus the medication "risedronate"; or 3) who take calcium and vitamin D plus participate in bone-loading exercises. Our central hypothesis is that improvements in bone health will be greater in women randomized to bone-loading exercises with calcium and vitamin D compared to women who take calcium and vitamin D only or women who take calcium and vitamin D plus risedronate.

Clinical Details

Official title: Randomized Control Trial of Bone Loading Exercises Versus Risedronate on Bone Health in Post-Menopausal Women

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Change in bone structure at hip and tibia based on randomization to Control, Risedronate, or Exercise group.

Secondary outcome:

Change in bone mineral density (BMD) at hip and spine based on randomization to Control, Risedronate, or Exercise group.

Change in serum measures of bone resorption (Serum NTx) and bone formation (AlkphaseB) based on randomization to Control, Risedronate, or Exercise group.

Detailed description: This randomized controlled trial (RCT) will compare changes after 12 months in bone structure, bone mineral density (BMD), and bone turnover in women with low bone mass who are within 5 years of menopause. Women will be randomized to one control and 2 treatment groups (n =103 per group): 1) optimal calcium + vitamin D (optimal CaD) alone (Control); 2) Bisphosphonate (BP) plus optimal CaD (Risedronate); and 3) a bone loading exercise program plus optimal CaD (Exercise). Our central hypothesis is that improvements in bone health will be greater in subjects randomized to the exercise group compared to subjects in either the control or risedronate groups. Specific Aims: Aims 1, 2, and 3 are to compare control, risedronate, and exercise group subjects on changes in bone structure at the tibia and hip (measured by pQCT and Hip Structural Analysis) (Aim 1) ; on changes in BMD at the total hip, femoral neck, and spine (Aim 2); and on changes in serum markers of bone formation and resorption (Aim 3). In addition, Aim 4 will explore relationships between adherence to exercise (% sessions attended) or adherence to risedronate (% pills taken) and changes in bone structure.

Eligibility

Minimum age: 19 Years. Maximum age: N/A. Gender(s): Female.

Criteria:

Inclusion Criteria:

- Women who are in their first 5 years of menopause

- Have a T score between -1 and -2. 49 at the femoral neck, total hip, or L1-L4 spine
