Brief Summary:
Osteoporosis is one of the most common skeletal disorders. Today in the United States, 10 million individuals have osteoporosis and 34 million more have low bone mass or osteopenia, which places them at an increased risk of some day developing osteoporosis. Of the people affected by this problem, 68% are women.The current thinking on the development of osteoporosis is that the changes in bone turnover that occur with aging play a major factor. Many modalities of treatment are used to prevent the bone loss and increased fracture risk associated with osteoporosis and osteopenia. Melatonin supplementation may be another treatment modality that lowers risk of hip fracture in perimenopausal women. Melatonin can remodel bone in animal models and in culture. Melatonin works through melatonin receptors to form osteoblasts from human mesenchymal stem cells and has been shown to inhibit osteoclast activity in rodents. Melatonin levels have been correlated with modulating bone markers; low nocturnal levels of melatonin correlate with in an increase in bone marker metabolism and osteoporosis. It is been shown that women who have worked night-shifts for greater than 20 years have increased risk for wrist and hip fractures. Night-shift workers have lower nocturnal melatonin levels than people who do not work the night-shift. The addition of exogenous melatonin suppresses bone marker metabolism. In human stem cells taken from bone marrow, melatonin increases the activity of bone-forming cells called osteoblasts. It is hypothesized that melatonin will improve bone health, menopausal quality of life and sleep compared to placebo in perimenopausal women. In particular, the investigators expect perimenopausal women taking melatonin to show an improvement in overall bone health as revealed by a reduction in bone marker turnover since bone resorption increases more so than bone absorption in this population compared to those women taking placebo. We also expect that perimenopausal women taking melatonin to have better control over their menopausal symptoms, better quality of life and less sleep disturbances when compared to their placebo controls since melatonin is known to modulate estrogen levels in the body and regulate sleep. The data from these studies may provide novel and alternative uses for melatonin; in particular its use for the prevention and/or treatment of osteoporosis.

Primary Outcome Measures :
- The Effect of Melatonin (3 mg) or Placebo on the Mean Change in Serum Osteocalcin (OC) Levels in Women After 6 Months, as Compared to Baseline [ Time Frame: Baseline and 6 months ]Osteocalcin is a measure of osteoblast activity because it is secreted from osteoblasts. Osteocalcin levels were measured in the serum of women at baseline and after 6 months of taking placebo or melatonin (3 mg) and the data are reported as ng/mL. Osteoblasts are bone-forming cells so a more positive mean change in osteoblast activity over time (6 months - baseline) could indicate an improvement in bone mineral density. A more negative mean change in osteocalcin levels over time (6 months - baseline) could indicate a worsening of bone mineral density.
- The Effect of Melatonin (3 mg) or Placebo on the Mean Change in Serum Type-1 Collagen Cross-linked N-telopeptide (NTX) Levels in Women After 6 Months, as Compared to Baseline. [ Time Frame: Baseline and 6 months ]Type-1 collagen cross-linked N-telopeptide (NTX) levels were measured in the serum of women at baseline and after taking placebo or melatonin (3 mg) nightly for 6 months. NTX, reported as bone collagen equivalents (BCE), is released from bone due to the actions of osteoclasts or bone breakdown cells. A more positive mean change in NTX levels (6 months - baseline) could result in a worsening of bone mineral density due to an increase in bone breakdown whereas a more negative mean change in NTX levels could result in an improvement in bone mineral density due to a decrease in bone breakdown.
- The Effect of Melatonin (3 mg) or Placebo on the Mean Change in Bone Density in Women After 6 Months, as Compared to Baseline. [ Time Frame: Baseline and 6 months ]The mean change in bone mineral density (BMD), represented by T-scores, was assessed by calcaneal ultrasound in women taking melatonin (3 mg) or placebo nightly at baseline and after 6 months. A T-score is a comparison of a subject's BMD to that of a healthy 30 year old female of the same ethnicity. The more negative the T-score, the worse the BMD. Osteoporosis or brittle bone disease is defined as a T-score -2.5 or less. A more negative mean change in a T-score would indicate a worsening of BMD. A more positive mean change in a T-score would indicate an improvement of BMD.
Secondary Outcome Measures :
- The Effect of Melatonin (3 mg) or Placebo on the Mean Change in Menopause-Specific Quality of Life (MENQOL) Physical Domain Scores in Women After 6 Months, as Compared to Baseline. [ Time Frame: Baseline and 6 mos ]Menopause-Specific Quality of Life (MENQOL) questionnaires were administered to women at baseline and after 6 months of taking placebo or melatonin nightly. The MENQOL is a validated questionnaire that measures 4 domains of menopause quality of life in women: physical, vasomotor, psychosocial and sexual with each domain having a scale of "not bothered" (score 0) or "bothered ranging from 1(not too bothered) to 6 (really bothered)". A more negative mean change for each of the MENQOL domain scores indicates an improvement of these symptoms and a more positive value a worsening of symptoms.
- The Effect of Melatonin (3 mg) or Placebo on the Mean Change in Menopause-Specific Quality of Life (MENQOL) Vasomotor Domain Scores in Women After 6 Months, as Compared to Baseline. [ Time Frame: Baseline and 6 mos ]Menopause-Specific Quality of Life (MENQOL) questionnaires were administered to women at baseline and after 6 months of taking placebo or melatonin nightly. The MENQOL is a validated questionnaire that measures 4 domains of menopause quality of life in women: physical, vasomotor, psychosocial and sexual with each domain having a scale of "not bothered" (score 0) or "bothered ranging from 1(not too bothered) to 6 (really bothered)". A more negative mean change for each of the MENQOL domain scores indicates an improvement of these symptoms and a more positive value a worsening of symptoms.
- The Effect of Melatonin (3 mg) or Placebo on the Mean Change in Menopause-Specific Quality of Life (MENQOL) Psychosocial Domain Scores in Women After 6 Months, as Compared to Baseline. [ Time Frame: Baseline and 6 mos ]Menopause-Specific Quality of Life (MENQOL) questionnaires were administered to women at baseline and after 6 months of taking placebo or melatonin nightly. The MENQOL is a validated questionnaire that measures 4 domains of menopause quality of life in women: physical, vasomotor, psychosocial and sexual with each domain having a scale of "not bothered" (score 0) or "bothered ranging from 1(not too bothered) to 6 (really bothered)". A more negative mean change for each of the MENQOL domain scores indicates an improvement of these symptoms and a more positive value a worsening of symptoms.
- The Effect of Melatonin (3 mg) or Placebo on the Mean Change in Menopause-Specific Quality of Life (MENQOL) Sexual Domain Scores in Women After 6 Months, as Compared to Baseline. [ Time Frame: Baseline and 6 mos ]Menopause-Specific Quality of Life (MENQOL) questionnaires were administered to women at baseline and after 6 months of taking placebo or melatonin nightly. The MENQOL is a validated questionnaire that measures 4 domains of menopause quality of life in women: physical, vasomotor, psychosocial and sexual with each domain having a scale of "not bothered" (score 0) or "bothered ranging from 1(not too bothered) to 6 (really bothered)". A more negative mean change for each of the MENQOL domain scores indicates an improvement of these symptoms and a more positive value a worsening of symptoms.
- The Effect of Melatonin (3 mg) or Placebo on the Mean Change in the Pittsburgh Sleep Quality Index (PSQI) in Women After 6 Months, as Compared to Baseline. [ Time Frame: Baseline and 6 months ]Pittsburgh Sleep Quality Index (PSQI) Questionnaire is a validated questionnaire that assesses the quality and quantity of sleep and sleep disorders.This survey is designed to identify "good" and "poor" sleepers and has a score scale that ranges from "0-21" with "0" being good quality of sleep and "21" being poor quality of sleep and/or indicating as having a sleep disorder. A more positive mean change in the PSQI over time indicates a worsening of sleep. A more negative mean change in the PSQI over time indicates an improvement in sleep.
