Effect of nasal calcitonin on the health-related quality of life in postmenopause women affected with low bone density

الملخص EN

Background : Physical activity and mental health could be affected by osteoporosis and various therapeutic options such as calcitonin may influence Quality Of Life (QOL) of these patients with Low Bone Density (LBD).

Objectives : This study aimed to evaluate the effect of nasal calcitonin on QOL in post menopause women with LBD.

Patients and Methods : This clinical trial study was performed on one hundred and fifteen menopause women with LBD less than 1 SD in Bone Mineral Densitometry (BMD) referred to Baqiyatallah Hospital in Tehran, Iran, during 2009 - 2010.

They were assigned to receive 200 IU calcitonin nasal spray along with calcium (1000 mg) and vitamin D (400 IU) for 6 months.

Quality of life was assessed by Short-Form 36 (SF-36) questionnaire (Persian-validated version).

Results : The mean age (± SD) of the participants was 58.75 ± 8.15 years.

Intranasal spray of calcitonin increased QOL scores significantly (88.05 ± 15.63 vs.

92.15 ± 13.22, P value = 0.000).

Bone mineral density of spine was increased from 0.834 ± 0.11 to 0.12 ± 0.852 and this difference in BMD of lumbar spine was statistically significant (P value: 0.003) but not significant in femur’s BMD (P value = 0.061).

In comparison with BMD indexes, The QOL scores especially Mental Health domain changes had only a significant correlation with the changes of total T score in BMD (P = 0.031, Coefficient Correlation = 0.248).

Conclusions : It seems that nasal spray of calcitonin can effectively improve QOL of women with LBD and QOL changes were not influenced by clinical or para-clinical alteration.

Mental health domain must be more considered in further studies as a predicting domain for Health-Related Quality of Life (HR-QOL) changes.
