The P.O.W.E.R. STUDY (Premenopause, Osteopenia/Osteoporosis, Women, Alendronate, Depression)

ClinicalTrials.gov · COMPLETED, 2007

220 participants

Abstract

The purpose of this study is to determine whether women with major depression lose bone mass at a faster rate than women without depression. This study will also determine if the drug alendronate can maintain or increase bone mass in premenopausal women with major depression and osteoporosis.

Depression may be a major risk factor for osteoporosis; it is associated with abnormally elevated stress hormone levels that may contribute to bone loss. This study will evaluate bone mass in women with depression and healthy volunteers.

Participants will undergo psychiatric, medical, dietary, and stress hormone evaluations and bone mineral density (BMD) measurements.

Participants with depression will be divided into two groups: those with normal BMD and those with low BMD. Depressed participants with normal BMD will be compared to a control group of healthy premenopausal women with normal BMD and followed for 36 months. Dual energy X-ray absorptiometry (DEXA) determinations will be made at months 6, 12, 24 and 36; bone turnover and endocrine parameters of depression will be

measured every 3 to 6 months.

Participants with depression and low BMD will be randomly assigned to receive either alendronate or placebo (an inactive pill) once a week for 24 months. Participants will receive calcium and vitamin D supplements daily. DEXA determinations will be performed at screening, and at Months 6, 12, 18 and 24; bone turnover and endocrine parameters of depression will be measured every 3 to 6…

How strong is the evidence?

Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 220 participants or records.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
