Further study details as provided by University of Aarhus:

Primary Outcome Measures:
  • Changes in Bone Mineral Density (BMD) [ Time Frame: baseline and end of study (after 12 months) ]
    Effects of melatonin on BMD will be assessed through DXA-scans

Secondary Outcome Measures:
  • Changes in Calcium Homeostasis [ Time Frame: baseline, after 3, 6, 9 months, and end of study (after 12 months) ]
    Calcium homeostasis will be analyzed through blood and urines samples

Enrollment: 81
Study Start Date: November 2012
Study Completion Date: June 2014
Primary Completion Date: June 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Melatonin1
1 mg melatonin nightly
Drug: Melatonin
1 or 3 mg of melatonin PO each night for 12 months
Active Comparator: Melatonin3
3 mg melatonin given nightly
Drug: Melatonin
1 or 3 mg of melatonin PO each night for 12 months
Active Comparator: Placebo
Identical placebo given nightly
Drug: Melatonin
1 or 3 mg of melatonin PO each night for 12 months

Detailed Description:

Background: Melatonin is known for its regulation of circadian rhythm. The production falls with age, which explains why elderly may have disturbed sleep patterns. Laboratory study and animal experimental studies suggests that melatonin also may protect against bone loss through increased osteoblast- and inhibited osteoclast activity. However, so far human studies have not been performed.

Design and patients: Double blinded randomised controlled study. Eighty post-menopausal women (aged 55-75) with osteopenia are randomized to receive 1mg, 3mg or placebo (daily - at night time) for 12 months.

Methods and results: Effects of melatonin on BMD, bone- structure and mass will be assessed through DXA-scans, pQCT, and QCT. Quality of life, sleep, and activity level will be assessed though questionnaires. Calcium homeostasis will be analyzed through blood and urines samples. As safety parameters, balance and muscle function will also be performed.

Conclusion: Expected improvements in BMD, quality of life and sleep.


Ages Eligible for Study:   55 Years to 75 Years   (Adult, Senior)

Inclusion Criteria:

  • Postmenopausal women between 55 and 75 years.
  • Osteopenia verified by DXA-scans of total hip or lumbar spine (t-score between -1 and -2.5)
  • Written informed consent after oral and written information

Exclusion Criteria:

  • Severely impaired renal function (plasma creatinine >60 eGFR ml/l).
